EXECUTIVE SUMMARY

Endeavour Mining Corporation, through its 100% owned subsidiary Avion Gold (Burkina Faso) SARL, has a 100% interest in the approximately 1,000 square kilometre Houndé Gold Project, situated in the South-western region of Burkina Faso. Ownership upon achieving production will be 90% by Endeavour and 10% by the government of Burkina Faso.

The Houndé Project feasibility study (FS) focuses on the Vindaloo group of deposits that are located approximately 250 km Southwest of Ouagadougou, the capital city of Burkina Faso. The deposits are approximately 2.7 km from a paved highway and as close as 200 metres from a 225 kV power line that extends from Cote d’Ivoire through to Ouagadougou. The nearby town of Houndé has a population of approximately 22,000. A rail line that extends to the port of Abidjan, Cote d’Ivoire lies approximately 25 km west of the deposit area.

Lycopodium Minerals Pty Ltd. was the FS study lead consultant with a focus on study coordination, metallurgy, infrastructure design and process plant design. Cube Consulting completed an updated mineral resource estimate. Knight Piésold Pty. Ltd. carried out pit and site geotechnical reviews, completed a water balance study and designed the tailings storage facility, water harvest dam and the water storage dam along with mine site drainage control elements. Orelogy completed the mine plan and mineral Reserve.

Mine environmental and social studies were completed under the lead of Genivar Inc. with SOCREGE and INGRID collecting social and environmental data, respectively. INGRID also completed an additional environmental and social study on the project’s water supply. Knight Piésold provided high level oversight over all of these studies.

Copies of the studies were presented to the government of Burkina Faso on November 7, 2013.

The following table presents the parameters used in the study.

The Vindaloo zones are hosted by Proterozoic-age, Birimian Group, intensely sericite- and silica-altered mafic intrusions and similarly-altered, strongly foliated and altered intermediate to mafic volcaniclastics and occasionally sediments. The mineralization is often quartz stockwork-style and is weakly to moderately pyritic. The Vindaloo trend has been drill tested for a distance of approximately 7.7 kilometres along strike and up to 350 metres depth. The intrusion-hosted zones range up to 70 metres in true thickness and average close to 20 metres true thickness along a 1.2 km section of the zone called Vindaloo Main. Volcanic- and sediment-hosted zones are generally less than 5 m wide. The entire mineralized package strikes north-northeast and dips steeply to the west to vertical. The mineralization remains open both along strike and to depth.

Sterilization drilling has led to the recognition of several parallel zones of gold enrichment, one of which, the Koho East zone, returned a drill intercept of 1.22 g/t Au over 21.0 metres. Several of these zones have the potential to add resources to the project.

Studies of 22 metallurgical samples from the Vindaloo and Madras NW zones indicated average assumed mill recoveries of 93.37%. Recoveries of 93.5%, for the Vindaloo Main zone fresh mineralization, were achieved by fine grinding of gravity concentrates to 80% passing 10 micron from an initial grind of 80% passing 90 micron. More than 70% of the gold is contained in the gravity concentrates.

During Q4, 2012 and Q1, 2013, Endeavour completed 40,534 metres of drilling in 358 holes with a specific goal of upgrading the Inferred in-pit mineral resources to Indicated resources and some Indicated mineral resources to Measured mineral resources. Endeavour’s drilling in conjunction with previous drilling comprises a drill database of 751 core and RC holes totalling 103,677 meters that supported the creation of an updated, in-pit mineral resources statement, which is summarized below.

The FS considered the owner operated development of five open pits over the Vindaloo and Madras NW zones over an 8.5 year time period, including 3 months of pre-strip. The Vindaloo pit would mine a series of closely spaced gold zones along an approximate 4.8 km strike length. The Madras NW pits would be mined along an approximately 900 metres long zone and would only mine saprolite and transition mineralization. Diluted proven and probable mineral reserves total 24.64 million tonnes grading 1.95 g/t Au totalling 1.55 million ounces (see table below). As well, 660,000 tonnes of inferred mineral resources grading 1.61 g/t Au lie within the pit envelope.

A water balance study indicated that a water harvest dam and separate water storage dam having combined storage of just over 3 million cubic metres would easily fill in one wet season and would contain sufficient water for plant operations demand during a 1:100 year dry season. Camp water would be sourced from nearby wells.

The processing plant consists of a 3.0 million tonne per year CIL plant with SABC milling circuit to produce an 80% passing 90 micron grind size. Ground fresh ore will feed continuous centrifugal gravity concentrators to recover free and occluded gold in heavy particles (pyrite) to a low mass gravity concentrate. This concentrate will be reground to 80% passing 10 micron grind size to feed a concentrate leach circuit. Gravity concentration tails will be thickened and feed a standard CIL circuit, with leach tails passing into a cyanide destruction process before being pumped to storage. Average production of 178,000 ozs/year over a period of 8.1 years is anticipated with a high of 215,200 ozs in year 2 and low of 136,800 ozs in year 7.

The tailings storage facility is located 4 km west of the plant in a natural valley. Studies indicate that the tailings storage does not need to be lined as the near-surface, clay-rich substrate would limit migration of tailings fluids away from the site. Decant fluids, though, are not suitable for release to the environment and will be pumped back to the plant. An impact assessment, including a dam break scenario, indicates a high consequence in the event of a wall failure and the tailings embankments were designed to reduce this risk. Closure will require covering the surface with 0.5 metres of broken rock. The facility has the potential to hold up to 100% more than is currently designed.

Power for the processing plant will come from the adjacent 225 kV power line that extends from Cote d’Ivoire to Ouagadougou. Sonabel, the state power entity, have agreed, in principle, to sell power to the project; however, the terms and conditions of this sale have not been defined.

Project staff will include approximately 470 people, not including catering and cleaning staff and miscellaneous contractors with 41 international and African expats and 430 Burkinabe employees. A camp to house 130 senior staff will be installed with the remaining employees living in the nearby communities.

An environmental and social impact and mitigation study, with a goal to be IFC complaint, was completed. The study outlines Endeavour’s responsibilities to the well being of the people and the environment during the development, operation and closure of the Houndé gold project. The project will require the acquisition of 2,096 ha of land. Several major land owners own the bulk of the land, however, numerous subsistence farmers rent portions of the land from the land owners. Compensation mechanisms for the land, buildings, trees and crops are part of the ongoing permitting process. Typical concerns, as a result of the project development include changes to quality of life, loss of livelihood, environmental degradation, potential for jobs, potential health issues, increase in traffic etc. Permitting is expected to take approximately a year to complete.

Houndé Capital Cost Estimate

The total estimated cost to bring the Houndé Gold Project into production is approximately $314.8 million, inclusive of contingency and working capital and an allowance for VAT and import duties. Additional deferred capital including closure costs, totals 87.6 million.

Houndé PEA Financial Summary

The Houndé Project generates the following financial results:

� At $1,300/oz gold price (Base Case) Post-Tax

- NPV at 5% discount rate totals $230.2 million

- IRR = 22.45%

- Payback 2.84 years from commencement of production

- Cash cost per ounce produced - $635.69/oz (excluding royalties)

- Cash cost per ounce produced - $713.65/oz (including royalties).

Conclusions and Recommendations

Independent studies of the mineral resources, metallurgy, mine plan, processing plant, capital costs, construction costs, environmental and social impact and relocation expenses have been carried out for the Houndé Project. These studies and subsequent cash flow model concluded that the project had an acceptable rate of return, even at current depressed gold prices and that Endeavour should proceed with project development. Should the project be developed, it is estimated that approximately 55% of the project’s net revenues would go to the state with a cash benefit of US$330 million over the project life.

1.2 Property, Access and History

Endeavour’s Houndé license area is situated in the southwestern region of Burkina Faso, West Africa (Figure 1.2.1). Administratively it is in the provinces of Tuy and Mouhoun.

The Houndé project Feasibility Study focuses on the Vindaloo and Madras NW group of deposits that are located approximately 250 km southwest of Ouagadougou, the capital city of Burkina Faso. The deposits are approximately 2.7 km from a paved highway and as close as 200 metres from a 225 kV power line that extends from Cote d’Ivoire through to Ouagadougou. The nearby city of Houndé contains approximately 22,000 people. A rail line that extends to the port of Abijan, Cote d’Ivoire lies approximately 25 km West of the deposit area with a rail siding at the community of Béréba.

1.4 Geology and Mineralization

The geology of West and Central Africa is dominated by Precambrian shields or cratons of Archaean and Lower Proterozoic age, Pan-African mobile zones of Upper Proterozoic age and intracratonic sedimentary basins ranging from the Proterozoic to the Quaternary.

The geology of Burkina Faso can be subdivided into three major litho-tectonic domains: (1) a Paleoproterozoic (Birimian) basement underlying most of the country, (2) a Neoproterozoic sedimentary cover developed along the western, northern, and south-eastern portions of the country, and (3) a Cenozoic mobile belt forming small inliers in the northwestern and extreme eastern regions of the country.

The Birimian crust in the project area comprises the following lithologies from bottom to top: (1) a thick sequence of mafic rocks, including basalt, locally pillowed, as well as dolerite and gabbro, all of tholeiitic composition, locally inter-layered with immature detrital sediments and limestone, (2) a detrital sedimentary pile (volcanics, turbidite, mudstone, and carbonate) including inter-bedded calc-alkaline volcanics, and (3) a coarse clastic sedimentary sequence belonging to the Tarkwaian Group. During the Eburnean orogeny, the volcanic and meta-sedimentary rocks were subjected to crustal shortening associated with greenschist facies regional metamorphism. Locally, amphibolite metamorphic facies are reached, but these occurrences are interpreted as resulting from contact metamorphism.

Rocks in the immediate Vindaloo and Madras NW zones comprises north- to northeast-trending greenschist-metamorphosed intermediate volcanics and sediments that are intruded by later gabbro sills and dykes.

The Vindaloo zones are hosted by an intensely sericite- and silica-altered mafic intrusion and similarly-altered, sheared and altered intermediate to mafic volcanoclastics. The mineralization is often quartz stockwork-style and is weakly to moderately pyritic. The entire mineralized package strikes north-northeast and dips steeply to the west to vertical. Drilling along the approximate 1.2 kilometre strike of the central core of the Vindaloo gold system has defined a coherent gold-mineralized, apparently shallow south plunging, zone that has been traced to at least 350 metres depth. Along strike, both to the north and south of the core of the Vindaloo zone, the gold mineralization can vary from weak to quite strong over relatively short, vertical or horizontal distances, leading to nodes of higher grade mineralization connected by zones of weaker gold mineralization.

The Vindaloo trend has been drill tested for a distance of approximately 7.7 kilometres along strike. The Vindaloo deposit open pit resources comprise a group of closely-spaced gold-mineralized structures that currently represent an approximate 4.8 km section of the Vindaloo Zone and a 0.9 km long section of the Madras NW zone. Modelling work has outlined 39 separate, semi-parallel lenses of mineralization, that are up to approximately 70 metres wide, that comprise the Vindaloo and Madras NW zones, of which 6 of the lenses contain the bulk of the mineral resources.

The Vindaloo zone mineralization is open along strike and to depth. Within and adjacent to the modelled area, there are indications of additional hanging wall parallel gold zones and gold-mineralized cross-structures. These areas are under-explored and need follow-up. There is a reasonable likelihood that additional drilling will result in additional mineral resources.

1.5 Exploration and Drilling

Mineral exploration in the Houndé area began in the 1939 by the Bureau de Recherches Géologiques et Minières (BRGM) and Bureau de Mines et de la Géologie du Burkina Faso (BUMIGEB) and continued to 1982. Exploration resumed in the 90’s with a group of companies that initially carried out regional geochemical surveys that were followed up by mode detailed geochemistry, prospecting, mapping and RAB to RC drilling as follow-up. Several gold zones were identified during this work, most of which still require follow-up today.

Endeavour initiated an in-fill drill program over the Vindaloo and Madras NW zones in late October 2012, with a goal to convert Inferred mineral resources to Indicated Mineral Resources and some of the Indicated mineral resources to Measured Mineral Resources. This program consisted of 358 holes totalling 40,534 metres. Including this drill program, during the period from 2007 to 2013, Endeavour, Avion Gold, Goldbelt and African Barrick completed 751 core and RC holes totalling 103,677 meters along the trend of the Vindaloo and Madras NW zones. All of this data has been digitized, incorporated into section sets, interpreted and used as the basis for this study. The data from these exploration programs is used in the current Mineral Resource estimate.

1.6 Mineral Resource

The updated Mineral Resource estimate for the Vindaloo deposits was completed by Cube in June 2013. This estimate represents an update of the Mineral Resources previously reported in the March 2013 PEA. All estimation work was carried out using SURPAC mining software and Isatis geostatistical software. Grade interpolation for gold has used Ordinary Block Kriging (OK) of downhole composite drill data.

The Vindaloo mineral resource is reported inside an optimized pit shell. The results from the optimized pit shell are used solely for the purpose of reporting mineral resources that have reasonable prospects for economic extraction, and the optimization was based on the following economic parameters:

� US$1,600/oz Au price,

� 94.7% to 97.7% saprolite recovery depending on zone,

� 88.1% to 94.1% transition zone recovery depending on zone,

� 79% to 94% fresh zone recovery depending on zone,

� $11.58 /t saprolite zone processing cost, including G&A of $0.99/t,

� $12.94 /t transition zone processing cost, including G&A of $0.99/t,

� $16.32 /t fresh zone processing cost, including G&A of $0.99/t,

� $2.11/t average mining cost,

� 31.6 to 54.0 degree pit slopes with the shallowest slopes generally in saprolite zones.

The Mineral Resource estimate was carried out using CIM guidelines (CIM 2005) by Cube Consulting and is reported at a cut-off grade of 0.35 g/t Au (Table 1.6.1), with an effective date of July 18, 2012.

Overall wall slopes were derived from the inter-ramp angles recommended by Peter O’Bryan and Associates, independent geotechnical consultants commissioned by Knight Piésold. ORELOGY utilised these parameters to develop the overall slopes for the optimisation, with the final wall slopes developed for five areas of the deposit.

Deposit characteristics and mining practices to be adopted led ORELOGY to estimate that the amount of mixing at ore / waste boundaries should be limited to a 1 m wide zone only, resulting in average values for dilution and ore loss within the Measured / Indicated orebody of 6.5% and 5.2% respectively.

The mining fleet used for developing the optimisation mining costs was based around a Caterpillar 785 140 tonne truck matched to a Caterpillar 6040 390 tonne excavator. Haulage costs were developed within the block model and flagged into a number of different zones, while drill and blast costs were developed from first principles. The optimisation cost estimate was based on ore grade control being carried out using reverse-circulation (RC) drilling in advance of mining. It was further assumed that 80% of the ore mined will be direct tipped to the crusher, and the other 20% will be stockpiled on the RoM pad and require rehandling with a loader.

The financial parameters used in optimisation process are summarised in Table 1.7.1 and a discount rate of 5% was used.

1.8 Mining

The mine design followed the concepts of the optimisation cost designs and the scheduling process aimed to achieve the following targets during each scheduling period:

� Plant feed rate of 3.0 Mtpa when the fresh rock proportion of the feed exceeds 75%.

� The mill feed is allowed to grow by a maximum of 15% in each period when the saprolite and transitional ore component exceed 25% of total. The throughput effects with varying proportions of saprolite and transition are shown in Table 1.8.1.

� A maximum plant feed grade of 4.0 g/t Au.

A groundwater investigation in the Vindaloo Pit area identified no primary aquifers in the vicinity of the Vindaloo Pit. Bulk permeability and storativity values were predicted to be low and to be largely controlled by the weathering profile and possible deeper fracturing / faulting. Based on standard analytical flow equations the estimated groundwater inflow to the pit (excluding incident rainfall and surface water runoff) is 6 L/s when the Vindaloo Pit is fully developed.

1.9 Metallurgical

1.9.1 Testwork

The metallurgical treatment route selected has been based on the results of testwork conducted on five primary ore composites and 22 individual variability samples from five mining areas and three levels of weathering. The primary ores represent approximately 82% of the deposit with saprolite and transition ores making up the remaining 18%. Primary ore from the Vindaloo pit makes up 80% of the primary ores and is the major component of the Houndé deposit.

Comminution testwork indicated that the primary ores will require moderate grinding energy and have moderate abrasivity; however, the ores are highly competent and display a high resistance to impact breakage.

Initial gravity concentrates for all ores contained an average of 60% of the feed gold in 6% of the feed mass, but subsequent tests of the primary ores indicated that greater than 70% of the gold was recovered to a 2% mass gravity concentrate. Regrinding the concentrate to 80% passing (P80)10 μm prior to leaching achieved the largest increase in extraction with the overall gold extraction increasing by up to 7%. Separate leaching of the reground concentrate prior to combined leaching with the gravity tails was beneficial.

Grind sensitivity testwork on the primary composites indicated that lower residue grades, faster leaching rates and higher gold extractions are achieved with increasing fineness of grind. Evaluating these benefits against the increased costs led to selection of an optimum residence time of 24 hours with a conservative grind size of P80 90 μm.

1.9.2 Plant Design

The process plant will be designed for a nominal 3 Mt/y (9,000 t/d) throughput on the life of mine blend ore (88% primary and 12% saprolite + transition ores), although the mine will deliver predominantly saprolite and transition ores for the first 18 months of operation. The design will allow the nominal throughput to be achieved in 8,000 operating hours per year.

The flowsheet comprises a primary jaw crusher feeding a live stockpile and then to a SABC comminution circuit with 6 MW SAG and ball mills and recycle pebble crusher, producing a target P80 90 μm grind size. With fresh ore in the feed, the cyclone product will pass through a gravity concentration circuit that will extract 2.5% of the feed as concentrate to be reground to P80 of 10 μm before intensive leaching. Saprolite ore and the gravity tails will be thickened and combined with the leached gravity concentrate as feed for a standard CIL leach circuit. A split AARL 6.5 t elution circuit will recover the gold for electrowinning and the leach tails will pass to a cyanide destruction circuit using the SO2 / air technology to ensure plant tailings comply with the Cyanide Management Code. The leach feed thickener overflow will provide cyanide free water for use in the milling circuit, while decant return from the tailings dam will supply process water.

A moderate level of automation and remote control will be provided, to ensure safe operation of the plant and to control process conditions for optimum recovery, while still requiring manual inspection of equipment before starting. Operators will also monitor the plant to ensure that spillage is detected and cleaned up quickly and that good housekeeping practices are followed in compliance with safe working practices and country regulations.

1.10 Infrastructure

1.10.1 Roads

A new intersection will be constructed on the N1 highway for the 1.5 km long sealed main access road to the plant site. The 1 km long unsealed camp access road will branch off the main road. Service roads within the plant will be laterite surface designed for the truck and crane access needed for maintenance and delivery of consumables and reagents.

Access to more remote dams (10 km) and the tailings facility (4.5 km) will be on upgraded existing laterite tracks, but the tailings dam access road will be constructed alongside the pipeline corridor to provide maintenance access to the pipeline if needed. Within the plant area, unsealed roads will provide access around the processing facilities.

1.10.2 Water Supply

A water balance model estimated the demand for raw water at 3.3 Mm3 per year. The annual water demand for the process plant amounts to 2.85 Mm3, with an additional 0.54 Mm3 for dust suppression. The demand will be met from TSF decant, pit dewatering (including precipitation on the pit area) and runoff from the ROM pad and stockpiles with the shortfall to be supplied from a water storage dam which will be fed from a water harvesting dam. Groundwater resources were considered but are expected to be very small; however, they will be sufficient for potable water use.

1.10.3 Surface Water Management

Wherever possible, run-off from undisturbed areas will be diverted around the mining and processing operations. Clean run-off that has contacted disturbed areas or dumps will be collected in sediment control structures and then discharged, while run-off that has contacted process areas or ore piles will be collected and returned to the process plant for use there.

1.10.4 Tailings Disposal (Tailings Storage Facility)

The TSF will have a capacity of approximately 25 Mt and it is estimated that the tailings surface at full capacity will cover approximately 200 ha. The selected site has the potential to provide storage for up to 50 Mt of tailings by increasing the embankment height and, if required, adding a saddle embankment to the south of the facility. It is expected that the tailings will settle to a density of approximately 1.4 t/m3 initially, increasing to 1.6 t/m3 to give an overall final density of 1.55 t/m3.

The tailings acid base accounting indicated that the tailings would be acid consuming and assay results showed that the tailings solids had a low number of elemental enrichments, with arsenic, selenium and antimony significantly enriched and chromium slightly enriched. A comparison with soil intervention guidelines indicated that a number of element concentrations will exceed the guidelines, thus requiring a cover system designed to isolate the tailings facility from the environment on closure to prevent migration of tailings.

Arsenic and antimony were present in the supernatant liquor at levels which would require dilution before releasing into aquatic systems as surface flows. It will therefore be required to store up to a 1 in 100 year wet event on the TSF without release to the environment and a suitable seepage reduction system will be required to reduce the risk of tailings supernatant affecting the groundwater. Seepage analysis site indicated that the in-situ saprolite will provide a suitably low permeability layer.

A dam break analysis of the TSF embankments resulted in the classification of the facility as a “High” consequence rating. As a result Embankment 2, which has the largest potential impact in the event of a failure, was designed to mitigate this risk by using the downstream construction method, while Embankment 1 and Embankment 3, which are lower risk, will be built downstream for Stage 1 and centreline for subsequent stages.

At closure, the embankments will be rehabilitated and revegetated and the TSF surface will be covered with a layer of waste rock and a soil layer and shaped to be free draining towards the closure spillway.

1.10.5 Dumps

Waste Storage Facility (WSF) shells have been designed with the standoff distance between the pits and the waste storage facilities determined in accordance with safety bund requirements by the Department of Industry and Resources of Western Australia.

In order to realise cost savings now, rather than a potential cost saving at some point in the future it, was decided to allow the eastern WSF to be constructed on the Koho zone. No consideration was given to stand off distances between WSFs and villages or heritage sites as none were apparent in the vicinity of the mining area.

WSFs are constructed in 20 m high lifts with 37 degree face angles and are later reworked into their final landform during the WSF rehabilitation process.

1.10.6 Power Supply and Distribution

A major 225 kV power line supplying power to Burkina Faso from Cote d’Ivoire is located adjacent to the plant site. Sonabel, the national power company, has agreed in principle to sell the project power. However, the means and final cost details have not been negotiated yet. The preferred option is to erect a sub-station on this line to provide power to the mine and processing operations at 11 kV.

The mine and processing plant installed load is estimated to be 26 MW, with an average demand of 15.5 MW, which will be supplied to the plant HV switchroom near the mills. The large loads (mill motors and elution heater) will be supplied at 11 kV, with power distributed to the remaining drives at 415 V from local switchrooms and motor control centres.

Remote loads (the camp, tailings decant pumps, water dam transfer pumps and street lighting at the highway intersection) will be supplied by 11 kV overhead lines, with pole-top transformers reducing the voltage to 415 V.

1.10.7 Accommodation Camp

It is anticipated that a significant proportion of the workforce will be recruited from Burkina Faso, with a preference to those from the Houndé area, and reside in Houndé town; however, permanent accommodation to house 130 senior operations and mining workforce personnel will be provided approximately one kilometre to the north of the process plant for expatriates and personnel from outside the local district. Blockwork construction on concrete slabs and steel trussed roofs will be used for the kitchen, dining and common facilities, as well as for the larger rooms reserved for management, whilst converted sea containers will be used for the junior staff rooms.

1.10.8 Buildings and Support Facilities

The process plant support facilities will generally be constructed of a concrete slab on ground with structural steel frame and metal cladding. Office and amenity areas associated with the main structures will generally be of blockwork construction, but other facilities such as ablutions, control room, switchrooms, etc., will be prefabricated.

The mine services facilities allowed include a heavy vehicle washdown bay with water recycle, a workshop and warehouse and an administration building with shift change facilities, including toilets and showers.

Sewage from the accommodation camp, process plant and mining services facilities will be collected and treated in two separate package treatment facilities. Treated effluent from the accommodation camp will be discharged to a leach field or a surface spray field, while the treated effluent from the plant site and mining services area will be discharged into the tails hopper.

General solid wastes will be deposited into a landfill, but dangerous materials such as cyanide packaging, will be incinerated on site to prevent unauthorised use.

The estimates have been prepared from first principles, but do not make any allowance for escalation from the date of the estimate or any variation in exchange rates. The schedule allows for $30 million of losses carried forward at the start of the operation. An allowance for Import Duties has also been made in the operating cost schedule of 7.5% on 50% of the operating costs for mining, processing and G&A. Allowance has been made in the capital costs for Import Duties at the rate of 2.5% on an amount of $180 million, representing an approximate value of the goods and services to be imported.

1.12 Project Execution

The cost estimates have been complied on the basis that Endeavour will adopt an EPCM approach, with engineering commencing after the Board has given approval to the Project, and the necessary permits are in place.

The overall duration of the project from Board Approval to first gold is estimated to be 21 months. The critical path runs from the award of the EPCM contract through the process and detailed design to mill building structural steel supply, erection of the milling building and installation of the equipment before final completion of the piping and electrical activities to allow commissioning to proceed. The schedule is based on purchase orders for the SAG ball and UFG mills being placed immediately the project is approved.

1.13 Environmental

1.13.1 Baseline Conditions

As part of this study, two ESIA studies and a RAP (Resettlement Action Plan) study were carried out by Genivar Inc., INGRID and SOCREGE under Endeavour’s supervision. Baseline studies carried out over a period of nine months showed:

� The biological environment lacked flora and fauna diversity.

� The human environment was dominated by traditional community structures and a low level of development based on a cash crop and subsistence economy.

� The ambient air quality contained high background levels of dust and the noise environment close to the highway had noise levels close to existing IFC limits.

� Water sampling showed on average the water quality is slightly acidic and pH of water at individual sites may be lower than the low limit in the WHO standards. Many of the surface water and well sites exceeded turbidity limits and a few sites had iron, chromium and manganese levels in excess of the WHO standard.

Key environmental issues identified include:

� Water supply for the mine;

� TSF location and post-closure land use;

� Transport and management of hazardous materials;

� Proximity of infrastructure (road, power line and optic fibre cable);

� Potential for in-migration and its effect on level of service in public infrastructure;

� Allowance for traditional grazing patterns; and

� Resettlement and reallocation of land.

Page 1.19

October 2013 Lycopodium Minerals Pty Ltd

1.13.2 Permitting Requirements

The key environmental permit required by the project is the environmental certificates from the Ministry of Environment and Sustainable Development (MEED) which will follow submission of the EIA and RAP. A number of secondary approvals may also be needed in relation to specific elements of the project, such as licences for dams, transport and storage of dangerous goods, highway intersection works, etc. These activities are likely to take 12 to 14 months:

Submission of the ESIA reports (Phase 2), public hearings and updates: complete by end April 2014.

Industrial Operating Permit application: estimated reception by end August 2014.

Operations Approval, signed Mining Permit: estimated reception 1 December 2014.

1.13.3 Social and Community Impact

Endeavour, through its subsidiary Avion Gold, has put in place a mechanism for gathering information and consulting the communities throughout this process, including a Stakeholder Engagement Plan (PEPP) and development of various information tools. Items of concern raised during community contacts related mainly to:

� Employment opportunities and possible influx from outside the area.

� Resettlement actions and future standard of living.

� Effect of the project on water and other local infrastructure.

� Possible health impacts and negative impacts on local moral standards and security.

� Impact of the project on current artisanal gold mining activities.

The project will also have positive impacts,

� Wages and salaries paid and spent in the region and services procured from local businesses.

� Training and skills development.

� Compensation payments for land.

� Taxes, Royalties and levies paid to the state of Burkina Faso of approximately $330 million over the project’s life.

1.13.4 Land Acquisition

The mine will need to acquire 2.096 ha for the open pit, processing plant, waste piles, TSF, water harvest dam and water storage dam, as well as the necessary roads. As well, a 250 metre wide health perimeter has been delineated around the existing infrastructure for optional compensation and relocation. A further compensation perimeter, designated as a mitigated 50 dB(A) nighttime sound perimeter has also been delineated to provide a mechanism for those impacted by the mine noise the option of being compensated and moved to another location further from the mine.

Fair baseline compensation was determined from a detailed local study by SOCREGE under the supervision of Genivar and Endeavour. The process of determining the appropriate level of compensation is still proceeding with estimates ranging from $6.2 million to $15.8 million. For the purpose of this study, an overall compensation level of $12.0 million was allowed.

1.13.5 Closure Costs

The estimate cost of closure is US$26,384,000. This cost is based on a combination of resale, reuse, recovery and rehabilitation options for the facilities. The biggest single cost will be the cost of closure of the tailings storage facilities which require covering with a layer of fresh waste rock before adding a low permeability layer and topsoil for revegetation. Mine waste dumps will be battered down and covered with topsoil. Infrastructure items of use such as dams, roads, office buildings, accommodation camp, etc, will be donated to the community, while the process plant will be demolished and the area rehabilitated.

The closure costs will be covered by a rehabilitation fund which is required to be set up upon opening of the mine. Contributions to the fund will match total material movement in the mine with $0.10 /tonne mined added to the fund annually, giving a closing balance will be $23.3 million, which will be topped up to $26.4 million (including contingency) at closure. This cost does not include provision for ongoing monitoring that may be required after closure and rehabilitation works have been completed. It is expected these could require ongoing monitoring of US$175,000/y, if required by the regulatory authorities prior to acceptance of relinquishment.

1.14 Economic Analysis

A simple cash flow model was prepared, based on the mine schedule and cost estimates. The results of the model are summarised in Table 1.14.1 and Table 1.14.2. At a gold price of $1,300 per ounce and full equity funding, the Project is estimated to have an after-tax IRR of 22.4% and a pay-back period of 2.88 years. At a discount rate of 5.0%, the after-tax NPV of this scenario is estimated at $230 million.

1.15 Recommendations and Conclusions

1.15.1 Conclusions

� Exploration drilling in the immediate Vindaloo and Madras NW pit areas indicates that there is both in-pit and near pit mineralized zones that merit follow-up in the short term, as their delineation could have a positive impact on the current mine and waste pile models.

� Exploration targets, located around the periphery of the Vindaloo and Madras NW pits, have the potential to add additional mineable resources.

� The Vindaloo mineralisation is sufficiently drilled and modelled to allow classification into a Resource Model that has been developed using generally accepted industry techniques and practices and conforms to CIM guidelines (CIM 2005). The mineral resource estimate is reported at a cut-off grade of 0.35 g/t Au with an effective date of July 18, 2012. The mine design and scheduling activities have resulted in a Reserve statement produced in accordance with Canadian National Instrument 43-101, ‘Standards of Disclosure for Mineral Projects’ of June 2011 (the Instrument) and the Definition Standards adopted by CIM Council in November 2010.

� The metallurgical testwork conducted on samples representing the bulk of the deposit to be mined has resulted in the development of a robust process flowsheet which is expected to recover in excess of 93% of the gold in the mill feed. Additional testwork on gravity concentration would improve the confidence of the design details and recovery estimates for this part of the process, and further testwork to optimise cyanide consumption may lead to reductions in overall operating costs.

� The preliminary design of the supporting infrastructure for the project has been carried out in sufficient detail to arrive at cost estimates of appropriate accuracy for study of this nature. One item still under negotiation is the connection to the HV power grid; while SONABEL has agreed in principle to supply power to the project, the details of the connection have not yet been agreed.

� Environmental studies have established the baseline conditions in the local project area and the efforts to mitigate the environmental impact of developing, operating and closure of a mine.

� A social impact assessment study has identified a number of areas of concern raised by the local community and identified appropriate mitigating actions. Overall, this study has demonstrated the economic and social benefits of the project for the area and the Country. A compensation and relocation plan has been developed for those that will be impacted by the Project.

� Based on the current reserves, production schedule, the metallurgical performance of the ore, the cost estimates, and other relevant criteria and parameters, the cash flow model indicates a robust project with an acceptable rate of return, even at current depressed gold prices.

1.15.2 Recommendation

Given the favourable economics of the project, it is recommended that Endeavour proceed with development of the project.

An exploration plan should be developed that matches the mine development schedule to ensure that any mineralized zones, that could positively impact the mine plan, are delineated in sufficient time to allow for the development of an updated mine plans.

4.3 Mineral Tenure

According to the Mining Act of Burkina Faso, exploration licenses are granted for a period of three years by the Minister of Mines, Quarries, and Energy. The Minister has the right to renew these licenses twice, for a period of three years per renewal. For each renewal, the size of each license will be generally reduced by 25%.

The exploration licenses are held by Avion Gold (Burkina Faso) SARL, (“Avion Burkina”), a company incorporated in Burkina Faso on January 29, 2010 and owned by Endeavour Mining Corporation. In a letter from legal counsel, Kere Avocats dated August 13, 2012 re: “Title Opinion on the Exploration Permits and related rights held by Avion Burkina, in Burkina Faso”, the opinion was given that all exploration permits and related rights were indeed held by Avion Burkina and were in good standing (Table 4.3.1). All new concession grants are pending since December, 2011, until the Government of Burkina Faso deals with outstanding concession applications; this includes all applied for areas indicated in Table 4.3.1. Endeavour has applied for 3 year special renewals for the concessions expiring in 2013; based on past precedents, Endeavour expects that the Bouhaoun, Kopoi and Wakui concessions will be renewed for an additional 3 years.

5.0 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

5.1 Accessibility

Ouagadougou, the capital city of Burkina Faso, is connected to Europe with daily flights by Air France and twice weekly by Air Burkina to Paris, three times per week to Brussels by Brussels Airlines. To East Africa it is connected twice weekly by Kenya Airways to Nairobi and to Addis Ababa by Ethiopian Airways. There are also frequent flights within the West African region to Mali, Accra, Cote d’Ivoire, Senegal and Niger.

The Houndé permits are located in the south-western part of Burkina Faso, West Africa centred over the city of Houndé. The Property area is accessible from Ouagadougou via paved Route National 1 (N1), for around 260 km. Driving the distance between Ouagadougou and the site takes approximately three hours.

Alternatively, access to the Property can be gained from Burkina Faso's second largest city of Bobo-Dioulasso near the border with Mali. The Property can be accessed by driving on Route National 1 (N1) towards Ouagadougou for 90 km. Access to the various parts of the permit from the paved road is provided by a network of roads and trails that were locally upgraded or built by Endeavour.

5.2 Climate

The Houndé permit area lies in the savannah of the Sudanese climatic zone characterized by increased influence of the West African monsoon relative to the Sahelian Zone to the North of Burkina Faso.

The weather station of Bobo-Dioulasso, 90 km to the west, has recorded an average temperature of 27°C over a period of 22 years, with a maximum of 43°C reached in April and a minimum of 9°C in December.

A rainy season lasting from June to October is followed by a dry season for the rest of the year. Monthly and daily historic hydrologic data for two climate stations in the vicinity of the project were used to derive baseline design climatology. These stations are:

� Houndé climate station, located 6.3 km north of the project site and

� Boromo climate station, located 74.7 km northeast of the project site.

The monthly precipitation values for average, 1 in 100 year dry and 1 in 100 year wet conditions and potential evapotranspiration (PET) data derived for use in calculations for the project are summarised in Table 5.2.1.

5.3 Local Resources and Infrastructure

The Route National 1 (N1) passes through the centre of the Houndé license area. The N1 is the country’s major paved highway linking the capital with the second largest city. It is also part of the main international highway in the Sahel region linking Dakar (Senegal) with Niamey (Niger) passing through Mali and Burkina Faso.

HOUNDÉ GOLD PROJECT, BURKINA FASO FEASIBILITY STUDY NI 43-101 TECHNICAL REPORT

1813.20\25.01\1813.20-STY-001_B S5

October 2013 Lycopodium Minerals Pty Ltd

The paved highway from the region’s main port Abidjan (Côte d’Ivoire) joins the Trans-Sahel road at Bobo-Dioulasso, which is located approximately 100 km southwest of the project area. The paved highway to the Ghanaian border and onwards to Accra and the Takoradi port is currently being upgraded.

The national electric grid’s main power line runs parallel to the main highway and passes through the property. Burkina Faso’s power generation capacity is being upgraded with the installation of new power stations and feed in from new power stations in Ghana. Access to this grid is currently being negotiated with the authorities to provide a convenient source of power for the project.

A railroad, which passes through the western side of the property, coming within 25 km of the proposed mill site, has a 400 m long siding (at the town of Béréba) and has been used to offload fuel and supplies. With a minimal of upgrading, this siding could be used to bring in fuel and construction and mining supplies. Endeavour has received preliminary pricing for rail freight for unloading at both Bobo Dioulasso and Béréba.

An abundance of unskilled local workforce is available. Skilled workers, and general services and equipment can be found in Bobo-Dioulasso or in the capital city, Ouagadougou.

5.4 Physiography, Topography, Elevation and Vegetation

The project area lies approximately 320 m above sea level and is characterized by gently rolling to flat topography with occasional round to steep laterite ridges to 20 metres high that are bisected with shallow northeast- to east-trending seasonal streams. A thin cover of soil, over laterite, covers most areas, with alluvium cover proximal to streams and drainages. Basement volcanic rocks and sediments outcrop locally with the most prominent being a large northeast-trending ridge of metavolcanic rock located approximately 5 km west of the deposit area. A typical dry season view of the area is presented in Figure 5.4.1. Trees and brushes are spaced from 1 to 100 metres apart with higher densities in drainage areas. During the wet season, grass covers the non-farm area and is often burned off after the dry season.

Figure 5.4.1 Typical View of Project Area Landscape

Small farm plots are common in the deposit area with a combination of cereal crops (corn, peanuts and millet) and cotton grown. Figure 5.4.2 shows a typical cotton field over the deposit area. Local orchards (mangoes, oranges and bananas) are located near drainages where there is a more consistent water supply.

Figure 5.4.2 Cotton Field in Project Area

5.5 Water

The project site is near the top of a watershed and hence there are no large permanent rivers in the vicinity. The nearest large surface body of water is the barrage at Pa, approximately 35 km to the northeast of the project site or the Bougiriba River about 40 km to the south of the project. With the short wet season and long dry season, surface water sources are intermittent; coupled with the flat topography, surface water storages are relatively inefficient, requiring a large area to store appreciable volumes. The high evaporation rates then cause appreciable water loss from such storages. A stream passing through the north east of the project area has the capacity to provide the bulk of the project’s water requirements, but suitable storage facilities are needed to ensure this water is used efficiently.

A barrage similar to that proposed for the project serves the local Houndé town; a photo of the resource taken in March 2013 (near the end of the dry season) (Figure 5.5.1) indicates that water can be stored successfully in the area.

Figure 5.5.1 Houndé Community Barrage

To the southeast of the mining area is a small formation of low hills which provides a convenient location for the construction of a more efficient water storage facility, although the catchment is too small to provide sufficient water. The project will therefore construct a water harvest barrage on the larger stream passing through the north east of the project area and water captured there will be pumped to the more efficient water storage barrage, from which the processing plant will draw water.

A hydrogeotechnical investigation was conducted at the project site in order to estimate open pit dewatering requirements and to identify potential sources of groundwater. The investigation concluded that the geology is “tight” and that groundwater sources will not supply appreciable volumes of water (see Section 18).

5.6 Waste Disposal Sites

5.6.1 Waste Rock

The mine design indicates that with a strip ratio close to 8.5, a total of approximately 210 Mt of waste rock will be produced from the open pits. The mineralisation of the project area comprises a series of SW – NE trending zones of which the Vindaloo is the main zone proposed to be mined. Waste rock dumps will be positioned to avoid the other mineralised zones identified on the site where practical, while keeping haul distances and costs to a minimum.

5.6.2 Tailings

Approximately 4 km to the north west of the process plant, a number of low hills provide a convenient location for a tailings storage facility capable of storing the approximately 25 Mt of tailings to be produced over the life of the mine, with potential to expand to a total capacity of 50 Mt. The topography will allow four small embankments constructed from local materials to contain the tailings in a footprint area of about 200 ha as shown in Drawing 100-G-001 in Appendix 18.1. See also Figure 5.6.1 and Figure 5.6.2.

Another location considered as a potential site for the tailings storage facility was the area to the south east of the project area now proposed as the location for the water storage barrage. While this area could also have accommodated the tailings, the presence of some mineralisation in the vicinity mitigated against this site being used to store a large mass of tailings.

5.7 Process Plant Site

The national highway, the 225 kV grid power line and the Vindaloo deposit mineralisation all tend to run parallel to one another in a SW – NE direction. A convenient location for the process plant exists between the power line and the open pit approximately halfway along the planned pit development, representing near-optimum haul distances for ore and easy access to the project infrastructure.

5.8 Flora and Fauna

Parkland and farm land occupies 85% of the zone's total surface area. Wooded savannah occupies 2% of the area. Shrub savannah represents 13%.

The geomorphology of the sites is characterized by plateaus (87%), upper slopes (6%) and lowlands (7%). The types of soil encountered are the gravelly (34%), clayey (60%) and hydromorphic (6%) types.

The forest inventory identified 68 species representing 24 families. The density of measurable trees (C1.30 �10cm) is 7 trees per hectare. The total number of trees is approximately 20,300. Density is relatively low due to the strong human presence and artisanal gold mining. For natural regeneration, density is 22 trees per hectare, i.e. about 63,778 trees.

Despite the rules of direct and indirect protection, wildlife habitat is severely degraded and no mammals have been observed.

The avifauna species found are present in types of preferential habitats: agricultural areas, relics of savannah shrub lands, hills and wetlands.

Fish fauna is limited by the ephemeral nature of the streams and local ponds in the project area. However, it is expected that fish species will increase with the emplacement of the water dam and water storage dam.

Bees are common during certain times of the year and caution must be taken to not disturb the nests as the bees can be quite aggressive. The bee species that is colonizing natural habitats or hives in Burkina Faso is Apis milifica adansonii a subspecies found in West Africa.

Two major groups of herpetological species have been identified including Colubridae and Viperidae. A survey of the area also reveals the presence of the spitting snake (Naja nigricollis).

6.0 HISTORY

Mineral exploration in the Houndé area began in the 1990’s. Previously, the Bureau de Recherches Géologiques et Minières (BRGM) and Bureau de Mines et de la Géologie du Burkina Faso (BUMIGEB) worked in the area intermittently from 1939 to 1982.

6.1 Ownership History

Following positive results from the UNDP regional geochemical surveys, Oxford Resources Inc. optioned the Kari Nord permit in 1998 and began an exploration program which, from 1998 to 2000, gained financial support from Avgold Ltd. of South Africa. Their program consisted of regional soil sampling (1,000 m by 250 m) and geophysical interpretation. Apparently, the soil survey indicated low gold values in the Vindaloo and Kari areas. A lack of funds stopped work in 2000.

The Kari Nord and Kari Sud permits were granted to Pyramide-M in 2004. Barrick Africa Exploration Ltd. Burkina (Barrick) acquired them in 2005. Then the permits passed into the hands of Goldbelt Resources West Africa SARL (Goldbelt) at the end of 2007. The Karba permit was initially held by Resolute West Africa (Resolute) from 2003 to 2006. In 2006, Goldbelt acquired the permit.

Wakui, Kopoi and Bouhaoun permits were initially held by Resolute in 2004, then by Goldbelt in 2006.

In late 2007 Goldbelt was purchased by Wega Mining (Wega), which was in turn purchased by Avocet Mining (Avocet) in June 2009. In October 2010, Avion Gold Corporation acquired Avion Gold (Burkina Faso) SARL, the subsidiary that was created to hold the Houndé permits (Kari Nord, Kari Sud, Karba, Wakui, Kopoi and Bouhaoun), from Avocet Mining. In October 2012, Endeavour Mining Corporation acquired Avion Gold Corporation and now owns a 100% interest in the Houndé Property (see Figure 6.1.1) through its 100% ownership of Avion Gold (Burkina Faso) SARL. Note that the original size of the permits has changed over time to reflect the permit renewal process and that the current map displays the current permit outlines.

6.2 Exploration History

Some of the first recorded work on the permits was a 1980’s regional scale UNDP soil survey where 28,300 samples were collected from a grid with spacings of 500 metres to 1,000 metres by 300 metres. These samples indicated several areas of gold enrichment in soil on the Houndé property. Regional magnetic surveys were also carried out over the same area by UNDP at the same time. Since the magnetic data indicated that the regional geology appeared to follow the trend of the artisanal workings the UNDP decided to carry out additional exploration in the Kari Nord permit area and specifically in the Kari Zone. Their initial follow-up work consisted of a soil grid with lines every 100 to 200 metres with samples collected every 50 metre along with lithogeochemical and geophysical surveys (magnetic and Max-min electromagnetic) and geological mapping. From this first pass, in 1997 the UNDP decided to drill 23 reverse circulation holes followed by twelve diamond drill holes in the Kari area. Five of these holes were reported to contain significant amounts of gold both visually and by assay.

From 2005 - 2007, Barrick conducted regional soil surveys (collecting a total of 912 samples), carried out geological mapping, completed 8,263 m of CBI drilling (cover-bedrock interface) in 544 holes, 9,264 m of RAB drilling in 279 holes, 70 m of RC drilling in one hole and 4 hole core holes totalling 625 metres on the Kari Nord permit. The core holes tested the centre of the Vindaloo Main zone with one of the holes returning 4.45 g/t Au over 34.0 m. After optioning the property from Barrick, Goldbelt in 2007 - 2009, conducted a detailed soil survey collecting 4,476 samples, carried out 1,344 m of RAB drilling in 92 holes, 9,483 m of RC drilling in 98 holes and 885 m of core drilling in 6 holes. In addition, they conducted a gradient IP survey at Vindaloo and Kari Pump for a total of 13.4 km². The best hole from this program returned 8.90 g/t Au over 29.0 m on section 49650N from the Vindaloo zone. Note that all Barrick and Goldbelt holes in the Vindaloo and Madras areas are part of the drill hole database that was evaluated and incorporated into the current Mineral Resource estimate.

From 2005 - 2007, Barrick conducted a regional soil survey collecting 949 samples, performed geological mapping, carried out 2,108 m of CBI drilling (cover-bedrock interface) in 153 holes and 4,656 m of RC drilling in 129 holes on the Kari Sud permit. Following up on this work, in 2007 - 2009, Goldbelt conducted detailed soil surveys collecting 382 samples and carried out 4,700 m of RAB drilling in 94 holes. The best hole from these two programs returned 3.47 g/t Au over 18.0 m from an area referred to as Vindaloo SE located approximately 4.4 km southeast of the Vindaloo Main zone. An evaluation of this area is still required.

The Karba permit was held by Resolute from 2003 – 2006. Resolute carried out 6,047 m of RC drilling in 130 holes. Interesting intercepts were returned from the Grand Espoir Zone: 2.65 g/t Au over 12.0 metres and the east end of the Kari area, 31.92 g/t Au over 3.0 metres. Goldbelt acquired the permit in 2006 and from 2006 to 2009, conducted regional and semi-detailed soil surveys collecting a total of 10,904 samples.

The Wakui permit was initially held by Resolute who conducted a regional soil survey collecting 3,718 samples in 2004 to 2005. From 2006 to 2007, Goldbelt conducted regional and semi-detailed soil surveys collecting a total of 2,996 samples. Subsequently they carried out 8,875 m of rotary airblast (RAB) drilling in 264 holes. Several holes drilled near the southern boundary of the concession in the Grand Espoir showing area returned anomalous results with hole WKRA009 returning the best intercepts of 2.26 g/t Au over 12.0 metres and 2.22 g/t Au over 8.0 metres. More work is required in this area.

Resolute conducted regional soil surveys on the Kopoi permit, collecting 3,599 samples during the period from 2004 to 2006. Kopoi was next held by Goldbelt from 2006 to 2007. During this period they conducted a regional soil survey collecting a total of 2,658 samples and carried out 3,850 m of RAB drilling in 77 holes.

The Bouhaoun permit was initially held by Resolute, who collected 3,270 regional scale soil samples, from 2004 to 2005. From 2006 – 2007, Goldbelt conducted regional and semi-detailed soil surveys collecting a total of 2,956 samples and carried out 4,988 m of RAB drilling in 215 holes.

After Avocet acquired the Houndé property in 2009, through its purchase of Wega, it completed 24 RC drill holes totaling 2,395 metres, carried out surface mapping and collected 243 rock samples and 49 soil samples. Avocet’s work focused on the western and northern parts of the property where assessment work was required. Drilling at the Douhoun occurrence returned a best intercept of 5.69 g/t Au over 14.0 metres core length at a vertical depth of 63.0 metres. This drill program also resulted in the discovery of the Kopoi occurrence where drilling return 3.43 g/t Au over 4.0 metres.

Avion commenced work over the Houndé property in early 2010, prior to the completion of the deal to acquire the Property. Initial work comprised a detailed airborne magnetic and radiometric survey, prospect review, soil sampling (2,808 samples collected on the Bouhaoun permit), chip and core re-logging and the completion of 34 drill holes totalling 5,515 metres mainly over the Vindaloo, Bouéré and Dohoun prospects. Upon completion of the drilling, Avion announced the first Mineral Resource estimate for the Vindaloo zone in late October 2010.

In 2011, Avion continued with the exploration program with 584 line km of IP gradient surveys over the Grand Espoir, Bouéré, Kari and Vindaloo areas, the collection of 324 soil samples over the Bouere and Vindaloo areas and the completion of 182 holes totalling 35,033 metres over the Vindaloo, Kari and Bouéré areas. Upon completion of this program, an updated Mineral Resource estimate was completed for the Vindaloo area. Anomalous drill results were returned from the Grand Espoir, Bouéré and Kari areas with holes returning best intercepts of 0.55 g/t Au over 34.0 metres, 24.18 g/t Au over 17.8 metres and 7.80 over 3.4 metres, respectively, at these zones; additional work is warranted over these areas.

In the first half of 2012, Avion continued the drill and geophysical program over the Vindaloo area completing 151 holes totalling 23,707 metres, 211 km of IP gradient surveys and initiated baseline environmental studies. As well, Avion commissioned an updated Mineral Resource estimate and a Preliminary Economic Assessment study (PEA), both of which were completed in early 2013.

Immediately upon Endeavour acquiring Avion in late October 2012, drilling resumed over the Vindaloo zone with a goal to convert Inferred Mineral Resources to Indicated Mineral Resources and some of the Indicated Mineral Resources to Measured Mineral Resources. This program consisted of 369 holes totalling 41,365 metres. In conjunction with this drill program base line environmental monitoring commenced and additional community consultations were carried out. Once the results of the PEA indicated a positive financial return, 22 composite core samples were collected for metallurgical studies with SGS Laboratories in Perth, a thin section report was prepared and feasibility level engineering studies were contracted. ESIA and RAP (Resettlement Action Plan) studies commenced in April, 2013 with the selection of consulting firms, and delivery of the Terms of Reference (TOR) to the government.

6.3 Resource History

Three previous resource estimates were calculated for the Vindaloo zone on the Houndé Property reflecting drill programs in each of 2010, 2011 and 2012. In each case, the overall resources increased each year.

6.3.1 2010 Resource Estimate

P&E Mining Consultants Inc. (P&E) completed the initial resource estimate carried out on the Houndé Property. Highlights of the Vindaloo initial resource estimate, at a 1.0 g/t Au cut-off grade, defined within an optimized pit shell as a constraint, are as follows:

� 883,000 tonnes Indicated Mineral Resources at 2.23 g/t Au totaling 63,000 Ounces 1, 2, 3, 4,

5, 6, 7

� 5,725,000 tonnes Inferred Mineral Resources at 2.97 g/t Au totaling 547,000 Ounces 1, 2, 3,

4, 5, 6, 7

1. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues and are subject to the findings of a feasibility study.

2. The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an Indicated or Measured Mineral Resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured Mineral Resource category.

3. The Vindaloo Zone Resource Estimates were prepared by Eugene Puritch, P. Eng. and Antoine Yassa, P. Geo. from P&E Mining Consultants Inc., Qualified Persons under NI 43-101 who are independent of the Company.

4. The Mineral Resources were estimated using the CIM Definition Standards - For Mineral Resources and Mineral Reserves, Prepared by the CIM Standing Committee on Reserve Definitions, Adopted by CIM Council on November 27, 2010.

5. The gold price used in this estimate was the June 30, 2010 two year trailing average of US$1,027/oz. Au recovery was 92% and mining costs were US$2.75/tonne of ore and US$1.50/tonne of waste. Processing and G&A costs combined were US$30/tonne. Pit optimization slopes were 50 degrees.

6. Effective date of June 30, 2010.

7. This resource is no longer current as it has been superseded by the resource estimate used in this feasibility study.

6.3.2 2011 Resource Estimate

P&E completed an updated resource estimate based on the additional drilling carried out in 2011. The 2011 Mineral Resource estimate within an open pit constraint at Vindaloo showed:

� Indicated Mineral Resources of 13.41 million tonnes at 2.07 g/t Au for a total of 893,000 ounces of gold at a 0.5 g/t Au cut-off 1, 2, 3, 4, 5, 6, 7, 8.

� Inferred Mineral Resources of 10.71 million tonnes at 2.07 g/t Au for a total of 712,000 ounces of gold of gold at a 0.5 g/t Au cut-off 1, 2, 3, 4, 5, 6, 7, 8.

This Mineral Resource estimate for the Vindaloo zone represented a 1,400% increase in Indicated Mineral Resources from 883,000 tonnes Indicated Mineral Resources at 2.23 g/t Au totalling 63,000 ounces of gold (Avion news release October 25, 2010) to 13.41 million tonnes at 2.07 g/t Au for a total of 893,000 ounces of gold.

In addition, there was also a 30% increase in Inferred Mineral Resource from 5.73 million tonnes Inferred Mineral Resources at 2.97 g/t Au totalling 547,000 ounces of gold to 10.71 million tonnes at 2.07 g/t Au for a total of 712,000 ounces of gold.

1. Resource estimates based on a gold price of US$1,350 per ounce, a 90% process recovery, mining costs of US$1.50/ tonne, process costs of US$15/tonne and General and Administrative costs of US$4.00/tonne were used to determine the 0.5 g/t Open Pit cut-off grade.

2. Gold grades were estimated in a 5 m x 5 m x 5 m block model from capped 1.5 m composites utilizing inverse distance cubed interpolation. Composites were capped up to 30 g/t depending on the individual mineralized domain.

3. Eugene Puritch, P.Eng. and Antoine Yassa, P.Geo. from P&E Mining Consultants Inc., Qualified Persons under NI 43-101 who are independent of the Company, are responsible for these Mineral Resource estimates.

4. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

5. The quantity and grade of reported inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred Mineral Resources as Indicated or Measured Mineral Resources and it is uncertain if further exploration will result in upgrading them to Indicated or Measured Mineral Resource categories.

6. The Mineral Resources were estimated using the CIM Definition Standards - For Mineral Resources and Mineral Reserves, Prepared by the CIM Standing Committee on Reserve Definitions, Adopted by CIM Council on November 27, 2010.

7. The Mineral Resource estimate is as of the effective date of December 21, 2011.

8. This resource is no longer current as it has been superseded by the resource estimate used in this feasibility study.

6.3.3 2012 Resource Estimate

The 2012 Mineral Resource estimate was prepared by Eugene Puritch, P.Eng, Fred Brown, P.Geo. and Antoine Yassa, P.Geo. of P&E and was reported within a PEA study report titled “Technical Report and Preliminary Economic Assessment of the Houndé Gold Project, Burkina Faso, West Africa” prepared by SRK consulting of Vancouver, B.C., Canada.

The 2012 resource estimate for the Vindaloo zone at the Houndé Project represented an 80.2% increase in Indicated Mineral Resources to 23,708,000 tonnes at 1.91 g/t Au for a total of 1,456,000 ounces of gold. In addition, there is also a modest 18.6% increase in Inferred Mineral Resource to 12,210,000 tonnes at 1.91 g/t Au for a total of 752,000 ounces of gold.

The Mineral Resource estimate in Table 6.3.1 for the Vindaloo deposits is reported at a cut-off grade of 0.35 g/t Au, is contained within a conceptual open pit shell and has an effective date of October 31, 2012.

7.0 GEOLOGICAL SETTING, MINERALIZATION AND ALTERATION

7.1 Regional Geology

The geology of West and Central Africa is dominated by Precambrian shields or cratons of Archaean and Lower Proterozoic age, Pan-African mobile zones of Upper Proterozoic age and intracratonic sedimentary basins ranging from the Proterozoic to the Quaternary (Figure 7.1.1).

The Precambrian history of this part of Africa is commonly described as a process of progressive accretion of a series of successively younger mobile or orogenic zones or belts to the old crustal nuclei of early Archaean age. Occasionally, subsequent orogenic belts develop inside existing cratons, but more commonly they add to the size of older cratons by the addition of new crustal material along their margins.

Most of the cratonic nuclei in the area under discussion stabilized during the Archaean after the accretion of Archaean mobile zones subsequent to earlier orogenic events. The North Gabon Archaean nucleus for example, stabilized around 2.7 Ga. An exception is the West African craton, which stabilized much later at about 1.99 Ga after the accretion of vast areas of Lower Proterozoic (or Birimian) formations at the end of the Eburnean orogenic event. This fact has led to much confusion as to the use of the word craton in regard to West Africa in recent years.

The Man Craton is considered to be a remnant of a much larger craton that included the present day Guyana Craton of South America. This former craton was split by continental breakup in the Jurassic and the two segments have since drifted apart.

The Lower Archaean-Proterozoic shields consist essentially of granitic-gneissic terrains and of isoclinally folded volcano-sedimentary and sedimentary greenstone belts, which can be of either Lower Archaean or Proterozoic age. Both ages of greenstone belts are host to significant precious metal, base metal, and bulk mineral deposits in Africa and worldwide. Archaean greenstone belts exist within the Man Craton and host banded iron formation (BIF) deposits, Archaean mafic cumulate deposits and Mesozoic supergene nickel deposits and so are compositionally different from their later equivalents.

The Proterozoic greenstone belts of West Africa are also known as Birimian greenstone belts, named after the Birim River Valley in Ghana, where both gold and diamonds occur. They encompass a vast area of approximately 350,000 km² covering parts of Niger, Burkina Faso, Benin, Togo, Ghana, Ivory Coast, Mali, Guinea, Liberia, and Sénégal. In general the Birimian rocks lie outside of the cratonic Archaean areas and are sometimes thought of as mobile belts. Birimian rocks are locally unconformably overlain by Lower Proterozoic-age Tarkwaian Group conglomerates and volcanic. Tarkwaian rocks have been identified in Ghana and Burkina Faso and likely occur in Cote d’Ivoire as well.

The Proterozoic Birimian greenstone rocks have undergone orogeny in Eburnean times, which dates roughly from 1.99–2.19 Ga. The last orogenic event in West and Central Africa was the Pan-African of Upper Proterozoic to Lower Paleozoic age (600–450 Ma). This event completed the addition of new crustal material to the older shield areas composed of Archaean cratons and Proterozoic mobile belts.

The Pan-African also overprinted and partially obliterated older pre-existing sequences of Archaean to Proterozoic age. Pan-African mobile belts rim the western margins of the West African and Congo shields: Mauritanides, Rokelides, and West Congo fold belt. The Pan-African belt of Central Africa, also known as the Trans-Saharan mobile belt, occupies a vast area along the eastern margin of the West African and the northwestern margin of the Congo Craton. This zone, which is thought to have resulted from the collision between the West African Craton and an ill-defined continent to the east, comprises the Adrar des Iforas and Aïr stockworks in Mali and Niger, and large parts of Benin, Niger, Nigeria, and Cameroon.

The end of the Pan-African orogeny welded the various cratons and shields of all of Africa together to form the approximate shape of the continent of Africa. It is unclear to what extent older (Archaean-Lower Proterozoic) crustal material has been preserved within the Pan-African belts, without having been subjected to intense metamorphic reactivation.

Due to extensive cover by intracratonic basins and deep crustal reactivation during the Pan-African orogenic event, only segments of the original Archaean-Lower Proterozoic cratons are recognizable today in West Africa. The principal remaining segments of the West African shield are the Man Craton in Guinea / Sierra Leone, Reguibate in Mauritania, Kayes Inlier in Mali, and the Kedougou-Kéniéba Inlier in Sénégal and Mali. The vast Man-Leo Shield terrains, which extend from Guinea in the west to Benin and Niger in the east, make up the balance of the West African Shield.

The Archaean-Lower Proterozoic shields consist essentially of granitic-gneissic terrains and of isoclinally folded volcano-sedimentary and sedimentary greenstone belts, which can be of either Archaean or Lower Proterozoic age. Both ages of greenstone belts are host to significant precious metal, base metal, and bulk mineral deposits in Africa and worldwide. Archaean greenstone belts exist within the Man Craton and host BIF deposits, Archaean mafic cumulate deposits and Mesozoic supergene nickel deposits and so are compositionally different from their later equivalents.

Intracratonic sedimentary basins, which are virtually unaffected by any orogenic event, cover extensive parts of the region. They range from Upper Proterozoic to Quaternary age. Coastal basins of Cretaceous to Quaternary age occur along sections of the Atlantic coast. The majority of known diamond productive kimberlite and related rocks in West Africa have been discovered primarily within the Man Craton, which underlies Sierra Leone, Guinea, Liberia, and western Côte d’Ivoire. Kimberlite in these areas is either of Jurassic or Neoproterozoic age.

7.2 Local Geology

The geology of Burkina Faso can be subdivided into three major litho-tectonic domains: (1) a Paleoproterozoic (Birimian) basement underlying most of the country, (2) a Neoproterozoic sedimentary cover developed along the western, northern, and south-eastern portions of the country, and (3) a Cenozoic mobile belt forming small inliers in the northwestern and extreme eastern regions of the country (Figure 7.2.1).

The Birimian crust comprises the following lithologies from bottom to top: (1) a thick sequence of mafic rocks, including basalt, locally pillowed, as well as dolerite and gabbro, all of tholeiitic composition, locally inter layered with immature detrital sediments and limestone, (2) a detrital sedimentary pile (volcanics, turbidite, mudstone, and carbonate) including inter bedded calc-alkaline volcanics, and (3) a coarse clastic sedimentary sequence belonging to the Tarkwaian Group. During the Eburnean orogeny, the volcanic and meta-sedimentary rocks were subjected to crustal shortening associated with greenschist facies regional metamorphism. Locally, amphibolite metamorphic facies are reached, but these occurrences are interpreted as resulting from contact metamorphism.

The Houndé greenstone belt consists of NNE-SSW oriented volcano-sedimentary rocks that are roughly 330 km long by 60 km wide.

The Houndé greenstone belt is made up of andesites, subordinate amphibolitized basalts with intercalations of minor acidic volcanic, gabbroic bodies, greywacke to argillaceous sediments and banded chert. All these rocks are intruded by plutonic bodies consisting of granodiorite, tonalite and quartz diorite batholiths, then by granitic, granodioritic and tonalitic stocks and some small leucogranite intrusions.

The above assemblage is unconformably overlain by Tarkwaian Group pebbly sandstone which lies in thrust contact with the Birimian rocks along the eastern side of the belt of the property.

Many late, magnetic, dolerite dykes intrude the greenstone belt at different trends with northwest-trending dykes most common. Other dyke trends observed are east-southeast- and northeast-trending.

One prominent northeast-trending dolerite dyke divides the geology of Hounde into two major litho-tectonic domains that are evident on the airborne geophysics: (1) northwest of the dike, units trend northeast; and (2) southeast of the dike, units trend north to northeast. This major dyke appears to occupy a northeast-trending ductile shear zone.

7.3 Deposit Scale Geology

Rocks in the immediate Vindaloo and Madras NW zones comprise north- to northeast- trending greenschist-metamorphosed intermediate volcanics and sediment that are intruded by later gabbro sills and dykes (Figure 7.3.1). The intermediate composition units comprise, in order of abundance, coarse polymictic andesitic debris flows (Figure 7.3.1), ash to lapilli tuffs and massive flows. The sediments are well banded and comprise greywacke with subordinate sheared graphic argillite sections (Figure 7.3.2). Banded chert / siliceous horizons and massive pyrolusite rock lie near the eastern edge of the Koho zone, which is approximately 300 metres to the east of the Vindaloo zone. These rocks are conformably intruded by locally to pervasively altered gabbro (Figure 7.3.3). Gabbro sills are preferentially hosted by the coarse andesitic units and along the contact between the sediment and volcanic units.

Figure 7.3.4 Propylitically Altered Gabbro

The Vindaloo zones are hosted by intensely sericite- and silica-altered mafic intrusions and similarly-altered, strongly foliated and altered intermediate to mafic volcaniclastics and occasionally sediments. The mineralization is often quartz stockwork-style and is weakly to moderately pyritic. The Vindaloo trend has been drill tested for a distance of approximately 7.7 kilometres along strike and up to 350 metres depth. The intrusion-hosted zones range up to 70 metres in true thickness and average close to 20 metres true thickness along a 1.2 km section of the zone called Vindaloo Main. Volcanic- and sediment-hosted zones are generally less than 5 m wide. The entire mineralized package strikes north-northeast and dips steeply to the west to vertical. The mineralization remains open both along strike and to depth..

The Vindaloo deposit open pit resources comprise a group of closely-spaced gold-mineralized structures that currently represent an approximate 4.8 km section of the Vindaloo Zone and a 0.9 km long section of the Madras NW zone. A simplified section of the Vindaloo deposit is presented in Figure 7.3.5.

7.4 Structure

In the property area, the Houndé volcanic belt is bound to the east and west by thrust faults. The thrust faults form clear magnetic discontinuities with a northeast-trending thrust contact along the western edge and a north-trending thrust contact along the eastern edge of the belt.

A strong, northeast-trending, dextral shear zone cuts through the centre of the property. This shear zone, which lies approximately 3 km west of the Vindaloo zone, has a very sharp western edge, as defined by the magnetic data. The eastern edge of the structure is not well defined; however, magnetic data suggests that the shear zone may be 4 to 6 kilometers wide. To the east of this strong structure, shearing is focused along unit contacts with preference along the sediment-volcanic, volcanic-gabbro and sediment-gabbro contacts. Sediment units are often strongly deformed and display local graphitic shear zones, gouge and healed breccias.

Rocks in the deposit area generally dip steeply west and occasionally steeply to the east. There is also a suggestion that local z-folds create shallow to flat dipping sections. Plunge directions are not clear, however, the mineralization appears to plunge both shallowly to the south and steeply to the northeast.

Gabbro units appear to be boudined both along strike and to depth. The gold zones usually weaken or die out where the gabbro is absent.

7.5 Mineralization and Alteration

The Vindaloo and Madras zones are predominantly hosted by altered magnetite-bearing gabbro and to a lesser extent andesitic volcanic rocks and sediments. The gabbro-hosted zones range up to 70 metres in true thickness and average close to 20 metres true thickness in a section of the zone called Vindaloo Main. Volcanic- and sediment-hosted zones are generally less than 5 m wide.

The mineralized system is zoned with initial propylitic-style alteration along the outer edges of the system with the addition of chlorite and calcite stringers concurrent with the destruction of pyroxene, amphibole and plagioclase. In a poorly defined area, located to the west of the Vindaloo Main zone, the propyltic alteration is overprinted by a reddish hematitic alteration comprising disseminated hematite and hematite veinlets. As the mineralized zones are approached propylitic alteration gives way to increasingly intense, yellowish-colored, sericite-epidote-ankerite+-fucshite alteration of the fragmental andesites (Figure 7.5.1). In the strongly altered sections, especially near the gabbro contacts, the fragments are flattened with stretching ratios to 20:1. Occasional quartz-veined zones, with associated trace to 5% finely disseminated to locally crystalline pyrite, occurs in the altered andesites, especially in the hanging wall to the Vindaloo Main zone and in areas along strike of the gabbro-hosted zones where the gabbro is absent. These quartz veins are generally oriented parallel to foliation and shearing.

Figure 7.5.1 Sericite-, Epidote-, Carbonate-, Fuschite-Altered Intermediate Fragmental

The gabbro units display a similar alteration pattern as the andesite units with widespread propyltic alteration of ferro-magnesium minerals to complete destruction of the ferro-magnesium minerals at the expense of a medium grey mixture of sericite, ankeritic carbonate and quartz. Locally the sericite-carbonate alteration gives way to stockwork-type quartz veining with local silica-enriched rims (Figure 7.5.2) to the quartz veins and selective silica replacement of feldspar grains, with a focus near unit contacts. At least three directions of quartz veins have been noted (Figure 7.5.3). Fine grained to mm-size pyrite crystals are associated with; trace to 10%, up to 2 cm wide, quartz veins (trace to 2% overall in mineralized zones); pyrite-enriched haloes to the quartz veins and; occasionally as disseminations within the host gabbro. Locally fine pyrite crystals are aligned to form poorly defined veinlets. Generally, disseminated sulphide mineralization, returns low gold grades; however, in the Vindaloo NE area, good gold grades are associated with both pyritic quartz veined areas and in areas with disseminated pyrite.

Trace amounts to 1% arsenopyrite occurs as finely disseminated grains in some of the well mineralized areas. As well, trace amounts of chalcopyrite, sphalerite and rare native gold, tetrahedrite, electrum, Altaite (PbTe), galena and scheelite were observed. Native gold and electrum occurs along grain boundaries and locally within pyrite grains (Figure 7.5.3).

Figure 7.5.3 Pyrite Crystal with Fine Gold Grain Inclusion (Kjarsgaard, 2013)

Mineralogy has been defined both from observations during core logging and three sets of thin section evaluations. Thin section reports were prepared by Lester, 2010 (10 thin sections), Sawadogo, 2011 (34 thin sections),and Kjarsgaard, 2013 (25 thin sections). An excerpt from Kjarsgaard’s report is included below:

“The protolith was probably a leucocratic hypabyssal monzonite to monzodiorite with abundant euhedral to subhedral tabular plagioclase, lesser amounts of perthitic alkalifeldspar and minor to very little primary quartz and no trace of primary MgFe-silicates. [Kjarsgaard was provided with strongly altered gabbro and intermediate volcanic samples where the primary mineralogy was partially to totally altered.] Primary Ti-magnetite has been completely altered and only the octahedral exsolution lamellae remain as deformed lattices or fuzzy aggregates, now replaced by rutile. The original plagioclase feldspar and probably also the fine-grained interstitial matrix have been replaced by albite and variably sericitized to the extent that in some samples only pseudomorphs remain. The entire assemblage has also been extensively overprinted by fine-grained euhedral to anhedral poikilitic carbonate (mostly ankerite with an earlier low Fe-ankerite overgrown by later very Fe-rich ankerite). Only in the last five samples (no. 34 to 39) does green Fe-rich chlorite become a major component of the alteration assemblage probably indicating more mafic protoliths. Late veins of coarse albite and carbonate ± quartz are common and cross-cut earlier, thinner and more diffuse veinlets of quartz-carbonate-plagioclase or carbonate-sericite. Mineralization occurs in the form of very fine-grained euhedral to subhedral pyrite that is either disseminated or follows earlier quartz-carbonate ± sericite vein systems. Trace chalcopyrite occurs together with pyrite in most samples and in a few is accompanied by very fine-grained gold, tetrahedrite and/or sphalerite. Gold and tetrahedrite occur interstitial to and as inclusions in pyrite. Scheelite was found in a carbonate vein in sample no. 33.” Kjarsgaard, 2013.

Lester (2010) suggested two stages of mineralization as indicated below (Figure 7.5.4). Note that Lester’s paragenetic table was edited to reflect subsequent mineralogical observations. Kjarsgaard (2013) suggests that the bulk of the pyrite was emplaced early in the development of the system and field observation suggest that magnetite was primary and destroyed / replaced during the mineralization event.

7.6 Veining

Quartz+-albite+-carbonate+-pyrite veins, associated with the Vindaloo and Madras zones, range from 0.5 to 2 cm thick with the rare vein to a metre wide. During the period from 2011 to 2013 oriented core quartz vein data and other structural data was collected to support interpretation of the geology and mineralized zones. This data indicates that there are three main vein trends in the Vindaloo Main zone area, in order of importance, trending at 030 to 045 degrees, 060 to 070 degrees and 130 to 149 degrees (Figures 7.6.1 to 7.6.3). Veins that trend these three dominant directions vary significantly in dip, supporting the interpretation that most of the veining is stockwork-type in character.

8.0 DEPOSIT TYPES

8.1 Introduction

The West African Lower Proterozoic greenstone belts have produced world-class gold deposits, such as the Obuasi mines of Anglo-Ashanti Corp. in Ghana that have been in continuous production since 1897.

The gold deposits in West Africa have been classified into the following types:

1. Structurally-controlled, epigenetic lode or stockwork mineralization related to major shear zones with native gold (Poura, Burkina Faso; Kalana, Mali),

2. Structurally-controlled, epigenetic lode or stockwork mineralization related to major shear zones and characterized by the inclusion of gold in the crystal structure of the sulphides, often locked in arsenopyrite (Ashanti type: Obuasi, Ghana),

3. Stratiform deposits hosted in tourmalinized turbidites (Gara Deposit Loulo, Mali),

4. Disseminated sulphides hosted in volcanic or plutonic rocks (Syama, Mali; Yaouré, Ivory Coast; granitoid-hosted, Ayanfuri, Ghana),

5. Paleo-placer deposits: auriferous quartz-pebble conglomerates (Tarkwa, Ghana); modern placers (eluvial, alluvial).

The classic structurally-controlled or shear-hosted quartz, sericite schist gold mineralization model with alteration halo (Type 1) matches that of the Vindaloo and Madras NW deposits.

9.0 EXPLORATION

9.1 Introduction

Endeavour acquired Avion Gold Corporation in late October 2012, which included the wholly owned subsidiary, Avion Gold (Burkina Faso) SARL, which owns the rights to the Houndé Exploration Permits. Exploration that was carried out prior to the acquisition by Endeavour, has been presented in previous reports and most recently in the Preliminary Economic Assessment (PEA) report by Rykaart, et. al, 2013. Immediately after Endeavour acquired the right to the property, drilling resumed with a goal to convert Inferred Mineral Resources to Indicated Mineral Resources and to convert some of the near-surface Indicated Mineral Resources to Measured Mineral Resources. This drilling and a summary of the historic drill programs carried out over the Vindaloo zone, will be presented in Section 10, Drilling.

Upon reception of the PEA, which indicated a potential economically viable project, a 1 metre contour map was created, developed from a satellite image collected in January 2013, additional metallurgical samples were collected and sent to SGS Perth for processing, additional thin section work was contracted, an auger drilling program as part of a sterilization program, was completed, additional IP surveys were carried out, a sterilization drilling program was carried out, and feasibility, ESIA and Resettlement Action Plan (RAP) studies were initiated. With the exception of the auger drilling program, IP survey and a summary of near-by exploration opportunities, the rest of the exploration and technical study results will be presented in other sections of this report.

9.2 Auger Drilling Program

An auger drilling program was initiated over those areas likely to be impacted by mine infrastructure including the potential tailings pond sites, mine and camp sites, waste dump sites and water dam site (Figure 9.2.1). Auger holes were designed to drill through the overlying laterite and alluvium so that the upper metre or so, of saprolite could be sampled and sent to the laboratory for analysis. Auger holes were drilled 25 metres apart on lines spaced every 200 metres. In total 1,977 auger holes totalling 13,760 metres of drilling, were completed as summarized below in Table 9.2.1.

Samples, representing one metre of drilling, were collected in rice bags under the supervision of a geologist. Prior to splitting (to reduce sample size), the contents of the rice sack were stirred to produce a uniform mixture. The sample was then reduced to 2 kg using a coning and quartering procedure with the sample transferred into a numbered plastic sample bag with a corresponding sample tag, sealed and dispatched twice a day to the Houndé exploration camp. Note that all sample equipment (sample bowls and scoops) were bristle brush cleaned before collecting the assay sample and that the drill rods were metal brushed to remove any material sticking to the rods.

Figure 9.2.1 Summary of Auger Drilling Sampling Results

All assay samples were sent to SGS Laboratories in Ouagadougou where they were first crushed to 75% passing 2 mm with the sample passed over a riffle splitter with up to 1.5 kg of 2 mm material pulverized to 85% passing 75 microns with a ring and puck pulveriser to create a pulp. The pulp was then analysed for gold by fire assay method FAE505 with aqua regia digestion extracted into a DIBK (336-diisobutylketone) solution with AAS (atomic absorption spectroscopy) finish and a gold detection limit of 2 ppb. SGS operates a Quality System, which accords to ISO 17025 standards. The Quality Control systems in place are such that analysis of blanks, standard reference material, repeats and re-splits account for up to 25% of all determinations conducted. As part of the international group of SGS laboratories, the laboratory takes part in a regular Round Robin sample analysis to check for bias or systematic error. All the above include 5% random repeats for all routine mineral analysis, as well as confirmation of anomalous results.

Basic geological information, including laterite thickness and type and depth to saprolite, was collected for each hole.

The auger program was successful in defining several gold enriched trends that were either obscured by younger cover or not covered by previous soil sample surveys. Only the mine site and waste pile areas returned significant anomalous gold values from the auger drill program which aided in the definition of 11 anomalous zones that are indicated in Figure 9.2.2. As well, the auger drill data supports the northern extension of the Nema and Koho zones with the strongest Au anomaly identified near the likely northern extensions of the Koho zone.

9.3 Induced Polarization Sterilization Survey

Induced polarization (IP) gradient surveys were completed over three areas that might have been covered by mine infrastructure including the tailings pond, water dam and waste pile areas between February 14 and 28, 2013 by Sagax Afrique based in Ouagadougou. A total of 57.0 line km of IP survey was completed on lines spaced 400 metres apart (Figure 9.3.1) over the water dam and tailings sites and 200 metres apart over the waste dump site. IP gradient readings were taken every 25 metres. The IP data trends in conjunction with the auger survey Au results and geological information allowed for the development of targets and subsequent drill testing. Follow-up targets were only identified in the waste pile area with drill results presented in report Section 10. The results of the IP surveys are presented in Figures 9.3.2 to 9.3.4. Figure 9.3.2 also includes the interpreted gold mineralization trends from the auger drill survey.

A summary of the surveys over each area is presented in Table 9.3.1.

9.4 Exploration Targets

This section will present exploration targets proximal to the Vindaloo zone that were identified during the drill programs carried out over the Houndé property by Avion Burkina from 2010 to the end of the current in-fill and sterilization drilling program. In summary six mineralization trends, Vindaloo, Madras, Madras NW, Koho East, Nema and Yabiro, were identified. The Koho East, Nema and Yabiro trends will be discussed in section 10 with recent drilling. Each of the remaining areas will be presented separately below. Section references are based on detailed drill section sets (Figure 10.2.2), which will not be part of this report and can be accessed, with permission, from Endeavour.

9.4.1 Vindaloo Trend

Drilling along, and proximal to, the Vindaloo trend has intersected both mineralized zones and sericite-carbonate-epidote altered zones, without mineralization. As a general statement, the Vindaloo zones are open both along strike and to depth. The general location of most of the various target areas can be discerned from Figure 10.2.1.

Vindaloo South Target Area

Significant opportunities to extend the zone both to depth and along strike have been identified at the southern end of the deposit where the deepest holes along a 500 metres strike length showed either the best intercept on that section, below the 200 metre elevation or a significant increase in the width of the altered gabbro host for the mineralization. A section by section description, where there is drill information, follows:

� On section 48350N, the deepest hole, HE-12-01 returned 2.47 g/t Au over 5.7 metres and intersected a 25 metre wide alteration zone compared to hole HA-12-92, located 25 metres above which intersected 10 metres of altered gabbro.

� On section 48375N the alteration zone in hole HE-12-07, the deepest hole, is approximately 100 metres wide compared to hole HE-12-03, located 50 metres above, which has two, approximately 15 metre wide alteration zones. As well, hole HE-12-07 returned three high grade intercepts, located up to 75 metres below the pit floor which included 16.00 g/t Au over 8.1 metres, 9.57 g/t Au over 7.2 metres and 28.25 g/t Au over 6.8 metres. These intercepts are open to the north.

� The next set of holes to the north lie on section 48450N. The alteration zone on this section is approximately 100 metres wide and the deepest hole on the section, HA-12-41 returned intercepts of 1.38 g/t Au over 48.1 metres including 1.86 g/t Au over 10.1 metres located 10 to 50 metres below the pit floor.

� Another 50 metres to the north, on section 48500N, the deepest hole returned 6.27 g/t Au over 43.2 metres that lies within the pit envelope and an intercept of 3.07 g/t Au over 9.5 metres, below the pit floor.

� On section 48550N, hole H-11-18 intersected 2.84 g/t Au over 4.1 metres, at about 85 metres below the surface, which appears to be close to the upper extension of the high grade zone in this area. It is likely that there is better mineralization to depth.

� This concept that the zone significantly improves with depth is supported by an intercept on hole HE-12-08, of 4.18 g/t Au over 24.4 metres on section 48700N; this intercept is just below 200 metres elevation and just over 125 metres from surface. Between this hole and the high grade intercept in hole HE-12-06, there are no holes below the 200 metre elevation.

� More support for this concept comes from an intercept of 2.57 g/t Au over 26.3 metres in hole HE-12-09 on section 48750N. This hole intersects near the base of the planned pit, below 200 metres elevation and is the deepest hole on the section.

� Section 48775N deepest hole, HE-12-10, below the 200 metre elevation, returned 4.25 g/t Au over 10.0 metres.

� On section 48800N, the deepest hole, HE-12-11 returned a strong intercept of 10.63 g/t Au over 28.2 metres.

� The final section, 48850N, of this apparent high grade, apparently elevation-controlled trend, returned 4.68 g/t Au over 38.4 metres in hole H-11-77.

Vindaloo Far South Target

Vindaloo SW target area lies approximately 1,000 metres south of the proposed Vindaloo pit. This area lies along the strike extension of the Vindaloo pit and became an area of interest when a 2011 core hole returned 10.17 g/t Au over 8.0 metres core length (Table 9.4.1). In total, 11 holes totalling 2,343.5 metres were drilled along a 550 metre strike, in this area (Figure 9.4.1). The mineralized zone appears to be generally quite narrow with potentially economic values along an approximate 100 metre strike length. The generally low grade of the assay values is in contrast with logging observations which indicated strong alteration and quartz veining.

Soukou

The Soukou area lies approximately 2 km southwest of the Vindaloo Far South zone along the Vindaloo trend. This area is an artisanal mining area, that when last reviewed in Q2, 2012, encompassed an area approximately 200 metres wide by about 500 metres long. This area has not been sampled or drill tested.

Section 49000N Area

In this area, the holes HE-12-14 and HD-12-30 were not drilled far enough to either intersect the zone or entire zone. Holes on sections 25 and 50 metres to the south returned intercepts of 5.34 g/t Au over 7.2 metres and 5.99 g/t Au over 12.7 metres, respectively in this area. Hole HE-12-14 was not drilled far enough east to intersect the zone and hole HD-12-30 returned a partial intercept of 1.86 g/t Au over 1.0 metres.

Area North of Section 50600N near 50200E

In this area, the mineralized zone appears to jog to the west. Geologically, this mineralization correlates better with the Vindaloo West zone, that was intersected approximately 60 to 70 metres west of the Vindaloo Main zone, some 600 metres to the south. IP geophysical chargeability, indicates that the Vindaloo Main zone may extend further to the north than tested by drilling, as it is not uncommon for the mineralization to disappear when the gabbro unit is absent.

Section 51100N

On this section, the deepest hole, H-11-40, right at the pit base, returned 2.55 g/t Au over 37.0 metres. This intercept correlates with strongly altered gabbro and may indicate a steep northerly plunge to the mineralization in this area. The adjacent holes that test this vertical elevation lie 25 metres to the south and 75 metres to the north.

Zone Trend from 52000N to 52450N

In this section of the trend, the altered gabbro appears to increase in width to depth and attain down hole thicknesses of up of 150 metres (with subordinate unaltered gabbro). In other areas, where the altered gabbro increased in width, economic grade zones were intersected nearby.

Section 126475N (Rotated Grid)

The pit is being pulled down in the area by a hole, H-11-100, that returned 51.63 g/t Au over 8.0 metres. Holes in this area are spaced approximately every 50 metres. It would be prudent to better define this high grade area before mining.

9.4.2 Madras Zone

The Madras zone lies immediately north of the Vindaloo Trend pits, immediately east of the power line and the Madras NW pits. The Madras zone likely represents the northern continuation of the Vindaloo trend of mineralization. Previous work in the area included 13 holes totalling 1,725 metres with the most recent drilling being carried out in the first half of 2012. Best intercepts include 4.1 g/t Au over 8.0 metres in hole H-10-24 and 2.78 g/t Au over 22.0 metres in KNRC-032 (Table 9.4.2). This zone has not seen sufficient drilling to define mineral resources and until recently, the strike of the zones was not known. In Q1 and Q2 of 2013, artisanal activity increased dramatically to close to 1000 people and then declined to a handful by the end of the period. Their excavation activity indicated that the Madras zone comprises two en-echelon, northerly trending zones that have been traced for approximately 100 and 70 metres (Figure 9.4.2).

9.4.3 Koho

The Koho zone lies approximately 300 to 350 metres to the east of the Vindaloo Main zone. Drilling has traced the zone for 3.6 km along strike and auger drilling data indicates it will likely extend for another 900 metres further north for a total strike length of 4.5 km (Figure 9.4.4). Drilling has returned wide zones of low grade gold with intercepts of up to 112 metres grading 0.46 g/t Au and 27.2 g/t Au over 2.0 metres (Table 9.4.3). Avion Gold completed 11 holes totalling 1,855 metres. Goldbelt had previously completed 13 holes totalling 1,263 metres. The zone is hosted by strongly altered gabbro, similar in character to that which hosts the Vindaloo zone. Since this zone lies just outside of the pit area, locally displays economic grade and widths, and based on experience at the Vindaloo zone where strongly mineralized zones are often dependent on vertical elevation, additional drill testing is warranted.

9.4.4 Induced Polarization Survey Anomalies

Induced polarization geophysical surveys have been completed and compiled along approximately 18 km of the Vindaloo Trend (Figure 9.4.5) by Sagax Afrique during a period from 2010 to 2013. With the focus on the Vindaloo zones and Madras NW, there has been limited follow-up of this data. As a result, a substantial amount of the IP survey results, still require follow-up.

10.0 DRILLING

10.1 Introduction

Endeavour initiated an in-fill drill program over the Vindaloo and Madras NW zones in late October 2012, with a goal to convert Inferred Mineral Resources to Indicated Mineral Resources and some of the Indicated Mineral Resources to Measured Mineral Resources. This program consisted of 358 holes totalling 40,534 metres (Table 10.1.1). Including this drill program, during the period from 2007 to 2013, Endeavour, Avion Gold, Goldbelt and African Barrick completed 751 core and RC holes totalling 103,677 meters along the Vindaloo and Madras NW zones (Table 10.1.2). All of this data has been digitized, incorporated into section sets, interpreted and used as the basis for this study. The data from these exploration programs is used in the current mineral resource estimate and is described in in greater detail in Sections 11, 12 and 14 of this report: Sample Preparation; Analysis and Security; Data Verification and; Mineral Resource Estimate, respectively. As well, a PEA report titled Technical Report and Preliminary Economic Assessment of the Houndé Gold Project, Burkina Faso, West Africa by Rykaart et. al., 2013 and filed in Sedar under Endeavour’s name and a report titled Technical Report and Resource Estimate on the Houndé Property, Burkina Faso, Africa by Kappenschneider et. al., 2012, filed in Sedar under Avion Gold Corporation, present the pre-Endeavour drill programs in more detail.

In addition, during 2013, Endeavour completed 10 geotechnical holes, 12 holes to test substrate for infrastructure, 8 water test boreholes and 35 RC sterilization holes (Table 10.1.1). With the exception of the sterilization hole results which will be described in this section, the other drill holes will be described in other parts of the report.

10.2 In-Fill Drill Program

During the period from late October, 2012 to end of March, 2013, Endeavour completed 358 in-fill holes totalling 40,534 metres of which 39% of the holes were core holes (Figure 10.2.1) and the remainder were reverse circulation holes. These holes were drilled with a goal of converting Inferred Mineral Resources to Indicated Mineral Resources and converting some of the near-surface Indicated Mineral Resources to Measured Mineral Resources, within the PEA pit limits. According to the previous resource study (Rykart et. al., 2013), this objective of defining Indicated Mineral Resources could be achieved by designing and completing a drill program, with hole pierce points on the mineralized zones, every 50 metres; similarly, the objective of defining Measured Mineral Resources could be achieved with hole pierce points on the mineralized zones, every 25 metres.

In order to facilitate the drill testing of the Vindaloo zone, a false grid, oriented parallel to the bulk of the Vindaloo zone mineralization, was created. The false grid is anchored at UTM coordinates 441,600N and 1,261,900E with initial coordinates of 50,000 N and 50,000 E (Figure 10.2.2). This section set follows the zone trend for 4.35 km from section 48,125N to 52,475N at an azimuth of 035 degrees. At the northern end of the section set (52,475N), the Vindaloo zone trends more northerly. At this point, the Vindaloo section set is rotated back to UTM grid coordinates from 1,203,925N to 1,204,525N for an additional 600 metres. Sections that display down-hole geology, summarized geology, alteration, color-coded individual assays, assay composites, mineralization wire frames and potential pit outline, have been produced for every 25 metres along strike.

Modelling work has outlined 39 separate, semi-parallel lenses of mineralization that comprise the Vindaloo and Madras NW zones, of which 6 of the lenses contain the bulk of the mineral resources. The Vindaloo deposit, which includes Madras NW consists of a group of open-ended, closely-spaced gold-mineralized structures that can be traced for approximately 5.6 kilometres. The Vindaloo zone has been tested to a maximum depth of approximately 350 meters with individual lenses of gold mineralization up to approximately 70 meters wide. Open pit resources were modelled to a maximum of 300 meters depth. The Vindaloo zone mineralization is open along strike and to depth. Within and adjacent to the modelled area, there are indications of additional hanging wall parallel zones and mineralized cross-structures. These areas are under- explored and need follow-up. There is a reasonable likelihood that additional drilling will result in additional mineral resources.

The mineralization along the Vindaloo trend is subdivided into six general areas as shown in Figure 10.2.3. Typical sections through the better parts of Vindaloo South (Vindaloo section 48450N, Figure 10.2.4), Vindaloo Main (Vindaloo section 49750N, Figure 10.2.5), Vindaloo Northeast (Vindaloo section 51000N, Figure 10.2.6), Vindaloo 2 (Vindaloo North section 1264150 N, Figure 10.2.7) and Madras NW (section 14 of 42, Figure 10.2.8) zones are inserted for reference. Vindaloo West lies to the west of the Vindaloo Main zone and is presented on Figure 10.2.5. The mineralized zones generally dip steeply to the west and are generally hosted by altered gabbro intrusions. The Vindaloo 2 and Madras NW zones, located at the northern end of the deposit trend, dip moderately to steeply to the west.

10.3.2 RC Sterilization Drill Results

Of the 35 sterilization holes that were drilled, 16 holes returned intercepts of greater than 1 g/t Au over 1.0 metres, with 2 holes returning multiple drill intercepts. A summary of the significant results is presented in the following table. This program was successful in extending the Nema zone to the north, extending the Yabiro zone along strike and the discovery of the Koho East zone. The best intercepts of the sterilization program were returned from the Koho East zone with 2.65 g/t Au over 8.0 metres (Figure 10.3.2).

Figure 10.3.2 Significant RC Sterilization Results

The Nema trend returned a best hole of 1.15 g/t Au over 7.5 metres (Figure 10.3.2). This trend can be traced for approximately 3 km through a combination of anomalous Au values in auger samples and from drilling. At one point the Nema trend passes under a major power line.

The Yabiro trend was first intersected with drill holes designed to test induced polarization highs during the Vindaloo area drill program where an exploration hole returned 1.7 g/t Au over 4.0 metres. Subsequent drilling indicated that the Yabiro zone is likely two en-echelon mineralized structures (Figure 10.3.2) with a best drill intercept of 3.26 g/t Au over 3.0 metres. The remainder of the intercepts are less than 1 metre wide, true width. The Yabiro zone lies up slope from an up to 500 metre by 300 metre area of shallow, generally less than 1 metre deep, artisanal workings. The zone appears to be hosted by altered gabbro, which is similar in character to the host of the Vindaloo zone. One deeper hole on this zone (HD-13-157) indicated that the width of the altered gabbro increases to 25 metres wide at depth of 110 metres from surface. This zone is open along strike and to depth.

The Koho East zone discovery seems to be the most interesting zone that resulted from the RC sterilization program with intercepts to 2.65 g/t Au over 8.0 metres (Figure 10.3.2). This zone is hosted by quartz-veined and pyritic iron carbonatized massive mafic volcanic rocks. The quartz veins appear to be oriented as left stepping, en-echelon veins, trending N045, within a N025-trending corridor based on the small occurrence located 320 m south of HD-13-147. Visible gold in quartz veining was discovered during a site visit at the occurrence. The Koho East Zone pinches and swells, with the assay results demonstrating that there is gold enrichment (>100 ppb) over 3 to 23 metres even though, locally, the grades are not economic. From drilling and auger drilling results, the zone can be traced for approximately 1,000 metres. The northern part of Koho East Zone appears potentially economic over a strike length of 470 metres. It is open to the north along one of the intermittent creeks, and at depth. The southern part, however, appears limited both along strike and to depth, although the zone might pass to the west of holes HD-13-175 and HD-13-176 as there are no auger samples south of these two holes.

11.0 SAMPLE PREPARATION, ANALYSES AND SECURITY

From 2010 to June 2013 sample preparation, analysis and security have been under the supervision of at least two and up to six contract geologists employed on site at any given time. All samples collected by Endeavour, or by third parties contracted by Endeavour, were subject to quality control procedures that ensured that industry best practice was utilised for the handling, sampling, transport, analysis, storage and documentation of sample material and analytical results.

For sample preparation and analysis, Endeavour has used the services of SGS Bureau de Liaison (“SGS”) laboratories at Ouagadougou, Burkina Faso and Morila, Mali. SGS is also a global independent provider of assaying and analytical testing services for the mining and mineral exploration industry with consistent quality standards implemented across all regions. Whilst they are not formally accredited, the SGS laboratories at Ouagadougou and Morila operate to ISO 17025 standards. As part of the international group of SGS laboratories, all laboratories take part in regular Round Robin sample analysis to check for bias or systematic error.

11.1 Historical Sampling (Goldbelt Resources, Avocet)

Endeavour / Avion carried out drilling and sampling campaigns during 2010 to 2013. Prior to this, Rotary Air Blast (RAB), Reverse Circulation (RC) and diamond (core) drilling was carried out by Barrick, Goldbelt Resources and Avocet Mining.

The samples were analyzed by Abilabs (Mali) and SGS Ouagadougou. Blanks, standards and duplicates were used to test the accuracy of the respective labs. Generally, every 10th sample was a control sample for QA/QC purposes. Blanks, standards and duplicates were used in equal numbers.

11.2 Sample Submission

A sample submission form detailing the sample number sequences and laboratory instructions accompanied every sample dispatch. On arrival at the laboratory, the samples are checked by SGS against the submission to ensure all samples were received. At completion of assaying and once results have been delivered by SGS, Endeavour geological staff confirms that all the submitted samples were analyzed by the methods requested by the client.

11.3 Sample Preparation and Analysis

11.3.1 RC Drilling Samples

RC samples were collected as 1 m sample lengths in bags directly from the cyclone discharge at the drill rig. The sample was then riffle split into a numbered sample bag with the corresponding sample tag to produce a sample of approximately 2 kg in size. The riffle splitters, plates, tubs and working areas were cleaned with compressed air after each sample was processed. The remaining reject sample was returned to the bulk plastic bag and remained at the drill site. Representative drill chips are collected from each 1 m sample reject and glued to a sample board for future reference.

1813.20\25.01\1813.20-STY-001_B S11

Page 11.2

October 2013 Lycopodium Minerals Pty Ltd

Approximately 30 assay samples were placed in large polyweave bags and transported to the Endeavour exploration camp at Houndé. The samples were then transported to the laboratory by Endeavour personal or collected by SGS. All RC samples were sent to the SGS laboratory in Ouagadougou where they were logged into the laboratory information management system (“LIMS”), weighed and dried. The submitted samples were crushed and pulverised to 85% passing 75 micron using an LM2 pulveriser. The pulveriser was flushed with barren material after each sample. A nominal 50 g pulp aliquot was analysed for gold by lead collection fire assay with AAS instrumentation.

11.3.2 Diamond Drilling Samples

Diamond core was placed in steel core boxes holding either four metres of HQ size or five metres of NQ size core. Core trays were marked with the drill hole number and downhole distance for the start and finish of the core in the tray. Core orientation was undertaken in competent fresh rock and completed at the drill site. The core trays are transported from the drilling site to the Endeavour exploration camp at Houndé where the core is laid out for geological logging, photographing and other data collection.

Specific intervals for sampling based on lithology were identified during the logging process and the core was cut in half along its longitudinal axis with a purpose-built diamond-blade core saw. After the core was cut, the right hand side of the cut core (looking down hole) was placed in plastic sample bags and sealed with the remaining core left in the core box. The sample bags were then picked up by a representative of SGS when a sufficient number of samples were collected and transported to either SGS Ouagadougou, Burkina Faso or Morila, Mali.

On arrival at the laboratory, the samples were logged into LIMS, weighed, dried and finely crushed. Samples were crushed to a nominal 2 mm diameter using a jaw crusher, with a sub-sample of <1.5 kg taken using a Jones-type riffle splitter. Reject material was retained in the original bag and stored. The sub-sample was pulverised to 85% passing 75 micron using an LM2 pulveriser. Approximately 200 g was taken for assay and the remainder placed in a plastic bag. The pulveriser was flushed with barren material after each sample. A nominal 50 g pulp aliquot was analysed for gold by lead collection fire assay with AAS instrumentation.

11.4 Quality Assurance and Quality Control Programmes

A program of quality control (QC) and quality assurance (QA) has been undertaken by Endeavour to check for contamination, accuracy and precision within the drill sampling and assaying process. The types of check samples that have been introduced into the sample stream include blank samples (“blanks”), certified reference materials (“standards”), and field duplicate samples.

A total of 5,326 records for client introduced blanks, standards, and field duplicates with Au values were in the database of 77,054 Au records. This equates to a total insertion rate of control samples of approximately 7%. A more detailed breakdown is 2,071 standard samples (2.6%); 2,152 blank samples (2.8%) and 1,103 field duplicates (1.4%). In addition, 3,196 internal laboratory standard results (4.1%); 2,899 internal laboratory blank samples (3.8%) and 169 pulp duplicates were also produced and analysed during the time period.

In addition, the SGS laboratories have their own internal quality performance processes which follow best practice guidelines required for qualification under International Organisation for Standardisation (“ISO”) standards. The standard QA/QC protocols for the laboratories include the insertion of CRMs, blanks, duplicates and repeat assaying to monitor the quality of the preparation and analytical processes of the laboratory.

Overall, the QAQC samples have performed satisfactorily and indicate the sample data is suitable for mineral resource estimation.

11.4.1 Standards

A number of standards were used to verify the ability of the laboratory to accurately determine the gold values. For DDH and RC drill samples, one certified reference standard was typically inserted into the sample stream for each group of 20 samples (5.0%).

Fifty three different standards were utilised as control samples and are detailed in Table 11.4.1 below and Appendix 11.1. The G* series of standards used by Endeavour were obtained from Geostats Pty Ltd based in Australia. All others were internal lab standards from various sources. AMIS series was obtained from AMIS in South Africa. The AU* series was obtained from Data Analysis Australia, OX* and S* series from Rocklabs New Zealand, and ST* series being internal SGS standards.

Ninety five samples representing about 4.5% of the 2,071 client field inserted standard samples included in the database exceeded two standard deviations (SD) from the expected value for gold (Table 11.4.2 and Table 11.4.3). Two SD is considered to be the acceptable variance limit above which follow up of the associated sample assay batch is recommended. Additionally there were 50 samples representing 1.5% of the 3,196 internal laboratory inserted standards which exceeded two standard deviations.

The Houndé site technical department advised that 1,169 samples were re-assayed when a review of the sample results indicated that the standards returned assay values greater than 3 SD off the accepted data value. In addition, standards that returned assays values greater than 2 SD from the norm, in mineralized sections, were also re-run.

Some of the large deviations from the certified standard value can be attributed to sample handling errors, involving accidental switching of standards in the sample stream. The identified cases of sample switching and mislabelling of the standards represent about 1% of the data and were not accounted for among the failed samples in the final statistics. See Appendix 11.4 for further details regarding these samples.

There are 7 internal laboratory inserted standards which could not be analysed as there were not enough samples (4 or less).

There are biases both positive and negative, observed in most of the results from the field inserted standard. These biases were observed throughout the period being analysed affecting the SGS_MORILA laboratory, even though this laboratory analysed samples only during the 2012 period. The main standards involved were G907-7; at SGS_OUA and G301-3; G907-7 and G907-2; at SGS_MORILA.

There are 4 samples that could not be associated with a known standard. Their values could not be associated with any expected value as a possible misclassified standard ID. This may indicate possible sample swaps and should be investigated. See Appendix 11.4 for further details on these samples.

Although most of the assay biases are small (�5%) and can be attributed to expected instrument drift within the laboratories, some of the laboratory inserted standards also show positive and negative biases. The main standards affected are: AUOJ-6; SG56; SH55. A possible recalibration of OXK94 between December 2012 and January 2013 can be observed.

11.4.2 Blanks

Assay blanks are used to check the possibility of contamination during the sampling or analytical procedure and are inserted into the sample stream at a nominal frequency of 1 blank sample for each group of 20 samples (5%) submitted to the assay laboratory.

Two types of blank material have been included in the database. The first one has been field inserted and is made out of building sand prepared on-site. This material does not have a certified assay value; however, it is assumed to have a very low Au value (<0.01 ppm) which is well below the threshold for the mineralised zone. The second type of blank material is an internal control sample used by both SGS laboratories Ouagadougou and Morila. As no certified assay values are available for these blank materials, expected values of 0.01 ppm Au have been assumed which corresponds to 10 times the assay detection limit (0.001 ppm Au). Greater than five times the expected value (0.05 ppm Au) was considered an acceptable upper limit to assess for contamination.

A review of the data has shown that of the 2,152 field inserted blank samples contained in the database, 2 returned a gold value outside of the accepted limits, which is considered an excellent result. However, of the lab inserted blank samples 44 SGS_MORILA and 12 SGS-OUA, a total of 56 samples were outside of the accepted limits representing 2.6% of the total blanks inserted by the labs. See Appendices 11.2 and 11.4 for further information regarding these samples.

11.4.3 Duplicate Samples

The term duplicate is a generic name for a repeat measure of the original sample. Duplicates are used to verify the repeatability and degree of precision of the analyses. They can also be used to verify the quality of the sample preparation process. In addition, when duplicates are sent to a secondary laboratory, they can also be utilized to verify the accuracy of the results of the primary laboratory.

The results for pairs of duplicate samples (original and duplicate) are plotted as X/Y scatter plots, Q-Q plot, and relative paired difference plots (RPD). Scatter plots allow comparison of the data pairs and assessing general dispersion as well as the data regression and the presence of any outliers. Comparison of the duplicate pairs in a Q-Q plot will show if any bias exists within a particular grade range. Finally, RPD plots evaluate the relative differences in per cent between pairs and allow the relative precision of samples to be determined through the calculation of the average coefficient of variation (ACV). The calculation of the ACV was set to consider only values >0.01 ppm Au, which is considered the threshold for mineralised material. This type of chart also allows for the visualization of any bias or trend that may occur. The results of the analysis of these samples are outlined below in Table 11.4.6 and Appendix 11.3.

Field Duplicates

A total of 1,103 field duplicate samples were submitted to SGS_OUA and SGS_MORILA. All samples submitted, were RC field duplicates. There were no diamond field duplicates submitted.

In the analysis of the scatter plots, correlation coefficients were 0.673 at SGS_OUA and 0.907 at SGS_MORILA, with both datasets containing extreme outliers which were biasing the data. When the outliers were removed this improved the correlation coefficients to an acceptable level of 0.965 and 0.97 respectively.

Q-Q plots show poor precision at both laboratories particularly for values close to the detection limit. This was the case when a filter of 0.25 ppm Au was applied to both sets of data, in conjunction with the removal of the extreme outliers in both datasets. SGS_OUA also showed poor precision and repeatability for assay values >5.0 ppm Au.

The analysis of RPD plots show values of ACV of 34% for SGS_OUA and 50% for SGS_MORILA. This lower than expected level of precision improves to 32% and 26% after the removal of extreme outliers in conjunction with a filter of 0.25 ppm Au for both datasets was applied. This level of precision is just inside the recommended acceptable range for Au.

The field duplicate assays show acceptable precision at both laboratories after removal of outliers, however, it is recommended that the presence of these outliers be investigated as it could indicate:

� Sampling procedure / issues associated with low homogeneity of the pulp samples; and

� Poor precision of the assay laboratory.

Coarse Duplicates (Rejects)

There were no coarse duplicates available for analysis for this project.

Pulp Duplicates

There were no client initiated pulp duplicates available for analysis for this project.

A total of 169 internal laboratory pulp duplicate samples were analysed by SGS_OUA on approximately 1:20 samples per batch from 2012 onwards.

The scatter plot shows a correlation coefficient of 1.0 and an ACV of 7% which is an excellent result.

Umpire Duplicates

There were no umpire duplicate samples available for analysis for this project.

11.4.4 Recommendations

It is recommended for future drilling campaigns, that a smaller selection of certified standards be used, in order to have a more meaningful number of results for analysis.

Although the performance of the blank assay samples is very good, the natural variability in the assays for the BLANK (internal material) makes the determination of possible contamination issues difficult. A certified blank assay sample should be sourced to ensure a more homogenous and predictable assay result.

The levels of precision observed in field duplicates are considered acceptable. However, the presence of outliers creating bias in the datasets at both laboratories should be investigated as it may indicate underlying issues with laboratory procedures.

For diamond drill samples, the recommended standard practise is that one field duplicate is nominally inserted into the sample stream for each 30 samples (3.3%). The duplicate is generally a quarter cut core sample obtained from the remaining half core assay sample. When RC drilling, the supervising geologist should select one or two “mineralised” metre samples to be re-split and submitted as field duplicates.

It is recommended that a duplicate pulp sample be taken and analysed at the minimum rate of 1:40 at the same time as the original pulp sample is taken. This ensures that errors due to sampling procedure and analytical method are removed. In addition, when the samples are pulverised regular routine wet screening should be done in order to check that the grind size of the pulp is to contract specifications.

It is recommended that coarse duplicates be taken and analysed at the same lab at a minimum rate of 1:40 samples per batch.

It is recommended that 50 to 100 pulp samples per month from mineralised zones be submitted to a second independent laboratory selected by client as an umpire check of the assay grade.

In order to sufficiently explain likely causes for the data biases, datasets containing all available information should be presented in a standard format containing crucial information such as Date Labjob Received, Labjobno and LaboratoryID for Original and/or Duplicate datasets. In addition, access to a selection of the raw data files from each laboratory would enable a more accurate analysis of the data over time.

11.5 ICP Analysis

A total of 2,429 core samples were also tested for whole rock analysis and additional elements. 35 elements were analyzed, i.e. Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, S, Sb, Sc, Sn, Sr, Ti, V, W, Y, Zn, Zr.

The sample preparation was carried out by SGS Ouagadougou. The lab then sent the pulps to SGS Canada for ICP analysis. The method to arrive at pulps was the same as for Au testing.

11.6 Density Analysis

More than 2,000 density measurements were taken by Endeavour in 2012 and 2013. The samples were prepared and measured at site at Houndé by technicians under the supervision of geologists. The rock type and weathering (oxide, transition, fresh) was recorded.

Competent core was sawn to pieces of approximately 300 grams. In cases of highly oxidized rock, pieces of appropriate length were chosen. The samples were sun dried for two days before preparation. The density was then determined by the following procedure:

a) The dry sample was weighed and the weight was recorded in a spreadsheet.

b) The sample was covered with a thin wax film.

c) The wax covered sample was weighed and the weight was recorded.

d) The sample was put in water, weighed and the weight was recorded.

e) The density of the sample was calculated using the following formula:

SG= Specific Gravity A= mass of dry sample B= mass of waxed sample out of water C= mass of waxed sample in water D= density of paraffin (0.9)

11.7 Sample Security

All diamond core and split RC samples were trucked to Endeavour’s secure (walled and lockable) central exploration camp at Houndé. Once the diamond core was sampled, both RC and diamond samples have the QA/QC samples inserted into the sample stream. Assay samples were placed in sealed and numbered polyweave or plastic bags for transport. The samples are delivered by batch to the laboratory either by Endeavour personnel or collected by SGS. Upon receipt, the laboratory personnel signed off on the secure receipt of all the samples.

All aspects of the RC and diamond sample collection were conducted by personnel under the supervision of Endeavour’s experienced geological staff.

11.8 Author’s Comments

The Author witnessed all aspects of the collection, preparation and dispatch of drill samples carried out by Endeavour. The sample collection and preparation, analytical techniques, security and QA/QC protocols implemented for the Vindaloo Gold Project are consistent with standard industry practice and are suitable for the reporting of exploration results and for use in mineral resource estimation. The sampling procedures are adequate for and consistent with the style of gold mineralisation under consideration.

Table 12.1.1 summarises the main tables and fields in the database used for the Mineral Resource estimation. Three fields were introduced into the database as part of the audit completed by Cube. “Cube_dip” was included in the “SURVEY” table to remove inconsistencies with the recording of the down hole survey declination. “Use_in_resource” was included in the “density” table to identify the measurements considered by Cube as acceptable for use in the resource estimation. “CubeAu1_ppm” was included in the NewASSAY table and represents the validated Au field used for grade estimation.

Electronic laboratory certificate files supplied by SGS allowed 43% of the entire Au assay data to be validated. The 43% of records verified represent 65% of the assays used directly for the compositing and estimation process.

Subsequent to the completion of the Mineral Resource estimate, an additional drill hole database was supplied to Cube on the 31st July 2013. This database included corrections made to the azimuth of some drill holes which were not adjusted for the magnetic declination (-3.6 degrees). This error only materially affects holes with intersections below 300 m drill length. At this depth the error begins to exceed 10 metres and is present in approximately 5 drill holes. Given the error only effects the drill hole azimuth and the resulting correction is along strike of the mineralisation, the net effect is not considered material.

12.2 QAQC Analysis

A program of quality control (QC) and quality assurance (QA) has been undertaken by Endeavour to check for contamination, accuracy and precision within the drill sampling and assaying process. The types of check samples that have been introduced into the sample stream include blank samples (“blanks”), certified reference materials (“standards”), and field duplicate samples.

Overall, the QAQC samples have performed satisfactorily and indicate the sample data is suitable for mineral resource estimation.

12.3 Independent Verification Samples

During the author’s site visit, a total of 31 independent samples from 2 RC holes were collected. The holes were selected at random and the sample intervals were chosen to include a range of gold grades. The samples were split from the remaining coarse reject sample bag. For the sample submission, 2 standards and 1 blank sample were included in the sample sequence. The author personally transported the samples to the SGS laboratory in Ouagadougou. The sample submission requested analysis for gold using 50 g Fire Assay with AAS finish as this was the same technique employed for all resource sampling. The results were emailed electronically from the laboratory to the author. The results are tabulated in Table 12.3.1 and also presented graphically in Figure 12.3.1.

There is generally a good correlation between the original and independently taken samples and the results are considered by the author to be acceptable.

13.0 MINERAL PROCESSING AND METALLURGICAL TESTING

13.1 Introduction

Several comminution and metallurgical extraction testwork programmes have been performed on ore samples from the Houndé deposit. Two preliminary testwork programmes were completed on samples from the Houndé deposit under the supervision of Endeavour. The first programme was completed in 2010 at SGS Laboratory, Burkina Faso and the second programme was completed in 2011 at the Endeavour Mining Tabakoto Plant metallurgical laboratory, Mali. These programmes showed that the Houndé ores contain a significant amount of gravity gold and that high gold extraction by conventional cyanidation is achievable. Review of this testwork is not included in this section.

A third Houndé metallurgical testwork programme has been completed during 2013 at SGS Lakefield laboratory in Perth, Western Australia. This detailed testwork programme was developed and supervised by Endeavour with results interpreted by Lycopodium for use in the feasibility study. The results of the detailed programme are presented in this section of the report.

13.2 Metallurgical Summary

The metallurgical treatment route selected has been based on the results of the current testwork programme. Full testwork details and testwork results of the SGS testwork programme, conducted on the 5 primary ore composites and the 22 individual variability samples, are included in the SGS report available on request from Endeavour.

The Houndé project consists of 5 mining areas; Vindaloo, Vindaloo West, Vindaloo NE, Vindaloo 2 and Madras, and three levels of weathering; primary, transition and saprolite. The primary ores represent approximately 88% of the ore body with saprolite and transition ores making up the remaining 12%. Primary ore from the Vindaloo pit makes up 80% of the primary ores and is the major component of the Houndé deposit.

Comminution testwork indicated that the primary ores will require moderate grinding energy and have moderate abrasivity; however, the ores are highly competent and display a high resistance to impact breakage.

Gravity concentrates for all ores contained an average of 60% of the feed gold in 6% of the feed mass. Inclusion of a gravity concentration stage in the testwork procedure increased the leaching rate but had no impact on final overall gold extraction. A gravity stage was included in the testwork and in the plant design.

Grind sensitivity testwork on the primary composites indicated that lower residue grades, faster leaching rates and higher gold extractions are achieved with increasing fineness of grind. Whilst gold leaching continued to occur through to 48 hours, an optimum residence time of 24 hours was selected for the design and further testwork. The grind optimisation analysis indicated that similar net revenues at grinds of P80 106 and 75 μm were achieved. Evaluating the benefits against the increased costs led to selection of a conservative grind size of P80 90 μm for the design and for further testwork.

Gold extractions after 24 hours using gravity concentration and conventional cyanidation averaged 89% for the primary (excluding the low tonnage Vindaloo 2 ore), 93% for the transition and 95% for the saprolite ores.

Testwork to investigate regrinding of the gravity concentrate was conducted on all primary composites. The Vindaloo Main primary composite contained 46% free gold and 35% occluded gold in the 7% mass gravity concentrate. The relationship between mass pull to gravity concentrate and contained gold was investigated and showed that greater than 70% of the gold was recovered to a 2% mass gravity concentrate. Concentrate regrind and leaching testwork was completed at P80 25 μm, 15 μm and 10 μm with regrind improving gold extraction through liberation of occluded gold in the gravity concentrate. The finest concentrate regrind of P80 10 μm prior to leaching achieved the largest increase in extraction with the overall gold extraction increased by up to 7%. Separate leaching of the reground concentrate prior to combined leaching with the gravity tails is beneficial. Cyanide levels of 0.2 % w/v in the concentrate leach and 0.035% w/v in the combined leach were utilised.

High graphitic material from the western resource boundary that has potential for ore dilution was also tested. This graphitic material appears to have no preg-robbing characteristics and can be treated by conventional cyanidation.

Endeavour provided variability samples representative of the gold grades, lithologies and spatial distribution of the Houndé ore body. Variability testwork on the individual samples was completed to determine the level of variability within the Houndé ores and included a gravity concentration step but excluded the concentrate regrind step. While there is considerable variation in gold extraction throughout the ores, the variation for the same oxidation level within the same mining area is minor.

Ancillary testwork for plant design was conducted and indicates that the slurry rheology will not impact on processing, conventional aeration in the CIL is suitable and typical carbon loadings are achievable. Thickening testwork indicated that the primary ores will thicken with acceptable underflow densities. Cyanide destruction testwork showed that the air / SO2 process can be successfully employed to treat the CIL tailings stream to achieve CNWAD concentrations of less than 5 mg/L if required.

13.3 Metallurgical Sampling

The Houndé project consists of 4 deposit areas; Vindaloo, Vindaloo NE, Vindaloo 2 and Madras. Houndé ore mineralisation has been classified into three main types based on rock alteration and degree of weathering:

� Saprolite for strongly oxidised material found near the topographic surface

� Transition for weakly oxidised material, and

� Primary for unoxidised material located beneath the zone of weathering.

Drill core samples for the detailed testwork programme were selected by Endeavour personnel on the following basis:

� Representative of the Houndé ore types.

� Spatial location across the orebody.

� Obtaining samples with the expected range of gold head grades to determine the effect of head grade on overall gold extraction.

The drill core was combined to provide 22 samples (4 saprolite, 3 transition and 15 primary samples). Testwork was completed on the individual samples and on 5 primary composites made up from the 15 primary samples. Drill hole locations are shown in Figure 13.3.1 and sample and composite details are shown in Table 13.3.1 and Table 13.3.2.

The primary ores represent approximately 88% of the ore body with saprolite and transition ores making up the remaining 12%. Primary ore from the Vindaloo pit makes up 80% of the primary ores (or 70% of the life of mine blend) and is the major component of the Houndé deposit.

13.4 Metallurgical Testing

13.4.1 Head Analysis

Full elemental analyses were conducted on the 22 individual samples and 5 primary composite samples. The analyses are summarised in Table 13.4.1 and Table 13.4.2. The duplicate gold assays varied significantly for some samples and indicate the presence of free gold or gold nuggets. The mercury head grade was generally low; however, some Vindaloo primary samples assayed over 1 ppm Hg which is considered high. Endeavour advised that this may be due to contamination from artisanal mining activities and that mercury levels will continue to be monitored. If mercury levels are found to be elevated, a suitable mercury capture system will be allowed for in the plant design.

13.4.2 Comminution Testwork

Comminution testwork was conducted on the 15 individual primary samples to determine the variability of comminution parameters throughout the orebody and determine parameters for comminution circuit design. The results from the SAG Mill Comminution (SMC) tests were interpreted and ranked by JKTech. A single Bond ball work index test was completed on a composite of the 7 saprolite / transition samples. SMC testwork was not completed on this sample as the ore was too soft.

The comminution testwork results are summarised in Table 13.4.3. The primary ores have average Bond rod and ball mill work indices indicating moderate grinding energy requirement and moderate abrasion indices. The JK breakage parameters indicate the ores are highly competent and display a high resistance to impact breakage.

The comminution results were utilised by Orway Mineral Consultants (OMC) for comminution circuit selection and mill sizing. The OMC comminution report is available on request from Endeavour.

13.4.3 Variability Testwork

Variability testwork was conducted on the 22 individual variability samples at the beginning of the testwork programme to determine the metallurgical performance of the Houndé ores and the variability within them. All testwork was conducted at a grind size of P80 75 μm and included a gravity concentration step. The results are summarised in Table 13.4.4 and Figure 13.4.1 to Figure 13.4.3. There is considerable variation in gold extraction throughout the Vindaloo ores, although the variation for the same oxidation level within the same mining area is minor.

Overall 24 hour primary ore gold extractions varied between 57% and 92% with an average of 85%. The average gold extraction for Vindaloo 2 primary ores was significantly lower at 57% while the other primary ore were less variable (average 89%, range 83% to 95%). The gold extraction for the 8 Vindaloo primary samples varied between 85% and 92% and averaged 89%.

Overall 24 hour gold extraction for the saprolite ores averaged 95% with a range of 92% to 97%. The 4 saprolite samples showed minor variation in gold extraction despite originating from 4 separate mining areas.

Overall 24 hour gold extractions for the transition ores averaged 93% with a range of 89% to 95%. The 3 transition samples represented 2 mining areas with the 2 Vindaloo transition samples showing no variation in gold extraction.

Diagnostic leach testwork was completed on the 2 Vindaloo 2 primary samples which achieved the lowest gold extractions. The results are summarised in Table 13.4.5 and show that the samples had 22% to 35% of the gold occluded in sulphides and silicates and not readily amenable to cyanidation.

The gravity concentrate for all samples contained an average 60% of the gold in 6% mass. The Vindaloo 2 samples (saprolite, transition and primary) had lower gold distributions in the gravity concentrate and the primary samples had poor concentrate intensive leach extractions (average 24%). The primary samples, excluding the Vindaloo 2 samples, had high gravity concentrate gold distributions (average 69%) with an average intensive leach extraction of 90%. The saprolite and transition samples had high intensive leach extractions (average 99%).

13.4.5 Direct Cyanidation and Gravity / Cyanidation Testwork

Direct cyanidation tests with and without gravity concentration were conducted on the 5 primary composites and on the 7 saprolite / transition samples to determine the effect of a gravity stage on gold extraction and leach kinetics.

The effect of gravity on gold extraction and extraction rates for Vindaloo primary, transition and saprolite ores is shown in Figure 13.4.4. This effect was typical for the majority of samples and shows that inclusion of a gravity stage increased the leach kinetics but did not increase the overall 24 hour gold extraction.

All further testwork was completed using a gravity concentration stage based on the improved leach kinetics.

13.4.6 Grind / Extraction Testwork

Grind / extraction tests were performed on the primary composites at grinds of P80 150 μm, 125 μm, 106 μm and 75 μm to determine the effect of grind on gold extraction. The gold extraction results for the gravity concentrate intensive leach and overall 24 and 48 hour leaches for all primary composites are summarised in Table 13.4.7 with results for the Vindaloo Main composite illustrated graphically in Figure 13.4.5. The results typically indicate that lower residue grades and higher gravity leach and overall gold extractions are achieved with increasing fineness of grind; however, similar extractions were typically achieved typically for the P80 106 and 75 μm grinds. Leaching kinetics also increased as the grind size decreased.

Note: Overall leach results include gravity concentrate intensive leach and combined leachof gravity concentrate leach tails and gravity tails

The average amount of gravity gold in each primary composite over the 4 grind sizes and the extraction of that gold by intensive leaching is summarised in Table 13.4.8. Gold reporting to the gravity concentrate was highest in the Vindaloo Main primary composite (73%) and lowest in the Vindaloo NE2 primary composite (33%). Extraction of that gravity concentrate gold by intensive leaching varied between 78% and 93% over the 5 composites indicating that some of the gold is locked in the gangue and could be liberated by further grinding prior to leaching.

A test on the Vindaloo NE2 primary composite using lead nitrate addition as a leaching activator showed no improvement in gold extraction.

Additional work to increase the recovery of occluded gold from the gravity concentrate was completed and is discussed in Section 13.4.8.

13.4.7 Grind Optimisation and Residence Time Analysis

A grind optimisation and residence time analysis was completed to evaluate the effect of grind size and leach residence time on project economics. The analysis compared gold revenue against operating and capital expenditure for the grind sizes considered and for 24 and 48 hour leach times.

The analysis showed similar net revenues at grinds of P80 106 and 75 μm with the increase in gold revenue (recovery) at P80 75 μm offset by the increase in operating cost. A conservative grind size of P80 90 μm was selected for the design and for further testwork.

October 2013 Lycopodium Minerals Pty Ltd

Although gold leaching continued to occur through to 48 hours, the increased costs (leach reagents and CIL power and tankage) associated with the longer residence time were similar to the increased gold revenue. A residence time of 24 hours was selected for the design and further testwork.

The gravity concentrate intensive leach gold extractions for the primary samples and composites ranged from 16% to 96% with an average extraction of 85%. Further testwork was conducted on the five primary composites to investigate the effect on gold extraction of regrinding the 7% mass gravity concentrate prior to leaching. Gravity concentrate regrind sizes of P80 25 μm and 10 μm were tested with concentrate gold extractions increasing as the regrind size decreased. The results are summarised in Table 13.4.9.

Additional optimisation testwork was completed on a second Vindaloo Main primary composite (representing 70% of the Houndé ore) to investigate gravity concentrate treatment:

The amount of free gold in the gravity concentrate was determined using mercury amalgamation. The gravity concentrate contained 46% free gold and 35% locked gold with the remaining 19% of gold in the gravity tails.

The relationship between mass pull to gravity concentrate and contained gold was investigated with results presented in Figure 13.4.6. For the Vindaloo Main primary composite, greater than 70% of the gold was recovered to a 2% mass gravity concentrate. A target mass pull of 2.5% to gravity concentrate was selected for the plant design based on the results of this testwork.

Gravity concentrate regrind testwork was conducted at regrind sizes of P80 15 μm and 10 μm to confirm previous results and to determine whether a coarser regrind size was suitable. This repeat testwork was completed at a lower gravity concentrate mass of 3.4% in line with the mass pull selected for the plant design.

The primary composites showed a range of 24 hour overall gold extraction increases of 2% to 6% with a P80 10 μm regrind of the gravity concentrate prior to leaching (1% to 4% at a P80 25 μm regrind), based on a gravity concentrate mass pull of 6% to 7%. This increase is due to the liberation of the finer gold particles locked within the coarser sulphide and silicate particles that are reporting to the gravity concentrate. The repeat testwork on the Vindaloo Main primary composite confirmed the previous results (7% gold extraction increase to 95% overall gold extraction at P80 10 μm) at a lower 3.4% mass pull to gravity concentrate. The P80 15 μm regrind achieved a lower 4% gold extraction increase.

The additional testwork on the Vindaloo Main primary composite also investigated the effect of leaching cyanide levels, combined leaching of the reground gravity concentrate and the gravity tails (in comparison to the standard test of separate leaching of the reground gravity concentrate prior to a combined leach of the concentrate leach tails and the gravity tails) and oxygen sparging.

A higher cyanide concentration in the concentrate leach (1.0% w/v NaCN versus 0.2% w/v NaCN) increased the gold leaching rate but had no impact on the final 24 hour gold extraction. Gold extraction was essentially complete in 2 hours at the higher cyanide concentration compared to 4 to 8 hours at the lower cyanide level.

A range of cyanide concentrations in the combined leach of the concentrate leach tails and the gravity tails was trialled (0.05%, 0.035% and 0.025% w/v NaCN) with equivalent 24 hour gold extractions achieved at all cyanide levels.

The combined leach of the reground gravity concentrate and the gravity tails achieved a lower gold extraction (1%) at a lower overall cyanide addition and consumption than the separate concentrate leach tests.

The use of oxygen in the combined leach increased the leach kinetics but had no impact on the final 24 hour gold extraction.

The leaching reagent regimes and consumptions for the primary composites, including the concentrate regrind and separate leach stages, are summarised in Table 13.4.10.

13.4.9 Preg-Robbing Test

Endeavour identified the presence of high graphitic material on the western resource boundary that has potential for ore dilution. A preg-robbing test was carried out on a sample of the Vindaloo Main primary composite combined with 10% of the graphitic ore and indicated the graphitic material has no preg-robbing characteristics and could be treated by conventional cyanidation.

13.4.10 Bulk Leach Testwork

Bulk leach tests were completed on the Vindaloo Main primary composite to provide leached slurry samples for subsequent testwork. All bulk leaches achieved similar gold extractions and reagents consumption to the lower mass tests.

13.4.11 Ancillary Testwork

Rheology

Viscosity testwork was conducted over a range of slurry densities (40% to 65% w/w solids) on a Vindaloo Main primary composite and a saprolite / transition composite, each ground to P80 90 μm and adjusted to pH10.5. The saprolite / transition composite is more viscous than the primary composite; however, the apparent viscosities for both composites are within acceptable limits at the CIL design conditions of 50% w/w solids and viscosity modification is not required.

Oxygen Uptake Test

An oxygen uptake test was conducted on the Vindaloo Main primary composite to determine the change in the rate of oxygen consumption of the slurry. The results were typically below 0.05 mg/L/min, indicating that the ore has a moderate to low oxygen uptake rate and normal slurry aeration in plant practice should provide adequate dissolved oxygen concentrations in the leach solution for gold dissolution.

Carbon Loading Kinetic and Equilibrium Carbon Loading Testwork

A triple contact sequential carbon loading test and equilibrium carbon loading testwork were completed on samples prepared from bulk leaches of the Vindaloo Main primary composite with the results indicating that high carbon loadings are achievable. The modelling of the adsorption circuit for the process plant has been based on typical design values.

Thickening

Thickening testwork was completed by Outotec on a slurry sample prepared from bulk leaches of the Vindaloo Main primary composite. The testwork included flocculant screening, dynamic thickening and basic rheology tests. The ore settled well under conventional high rate thickening conditions.

Outotec calculated a thickening flux rate of 1.2 t/m2.h with a high rate thickener achieving an underflow density of 58 to 61% w/w solids. Outotec have indicated that densities 2 to 3% higher than those achieved in testwork should be achievable in a full scale thickener.

Cyanide Destruction – Air / SO2 Process

A series of batch cyanide destruction tests using the air / SO2 process were conducted on a Vindaloo Main primary composite bulk leach tails. A range of reagent addition rates were trialled and showed that the air / SO2 process can be successfully employed to treat the CIL tailings stream to decrease weak acid dissociable cyanide (CNWAD) concentrations to less than 5 mg/L if required. The CNWAD level in the test solution before commencement of tests was 150 mg/L and a batch residence time of 120 minutes (equivalent to 60 minutes in a plant continuous reactor) was sufficient to achieve acceptable tails CNWAD concentration. The results are presented in Table 13.4.11.

Tailings

Sample for tailings testwork was prepared from the tailings from bulk leaches of the Vindaloo Main primary composite. The tailings testwork evaluated the tailings settling characteristics and beaching properties and was completed by Knight Piésold. Details and results of the tailings testwork are summarised in Section 18.6.

13.4.12 Metallurgical Recoveries and Reagent Consumptions

The average results of the metallurgical testwork programme on the individual samples and primary composites are summarised by weathering, mining area and rock type in Table 13.4.12.

It is recommended that a constant recovery approach be assigned to each ore type group based on average testwork results. The testwork gold extraction has been discounted to estimate the anticipated plant recovery. This gives consideration to tailings soluble losses, potential for short circuiting in the leach circuit and other associated plant problems that may impact on the overall plant gold recovery. A 0.010 mg/L soluble gold loss has been allowed which is equivalent to a solid loss of 0.011 g/t Au at the expected CIL tailings slurry density of 48% w/w solids. The calculation of the anticipated Houndé Plant gold recoveries is summarised in Table 13.4.13.

The reagent consumptions from the testwork have been used to anticipate the plant leach reagent consumptions. Overall cyanide consumption was calculated based on the concentrate leach consumption at 0.2% w/v NaCN concentration and the average of the bottle roll leach testwork cyanide consumptions. A CIL tails allowance of 100 mg/L NaCN has been allowed which is equivalent to an additional 0.11 kg/t NaCN at the expected CIL tailings slurry density of 48% w/w solids. The average lime consumption in the testwork adjusted for the difference between 60% available lime used in the testwork and 90% available lime for the plant supply. The average sodium hydroxide consumption in the concentrate leach testwork was used.

The anticipated Houndé Plant gold recoveries and leach reagent consumptions are summarised in Table 13.4.14 and are based on:

� Saprolite ores - whole ore leach (no gravity concentration or concentrate treatment).

� Transition ores – gravity concentration and intensive leaching of concentrate and leaching of gravity tails.

� Primary ores - gravity concentration (mass pulls as achieved in the testwork programme), concentrate regrind to P80 10μm, intensive leaching of the concentrate and leaching of gravity tails.

Recoveries and reagent consumptions have also been nominated for two ore types not included in the testwork programme, Vindaloo NE1 and Madras NW transition, and are summarised in Table 13.4.13 and Table 13.4.10. Vindaloo NE1 ore has similar mineralogy and stratigraphic position to Vindaloo West and Vindaloo Mafic Volcanic and therefore a similar recovery and reagent consumption has been nominated. The testwork gold extraction for Madras NW saprolite was higher than that achieved for Vindaloo Main saprolite so a recovery and reagent consumption similar to Vindaloo Main transition has been allocated to Madras NW transition.

13.4.13 Technical Risks and Opportunities

A number of technical risk and opportunity areas have been identified during the testwork programme and subsequent process design.

Gravity Concentration

Two continuous centrifugal gravity concentrators have been selected in the plant design to recover a 2 to 3% mass gravity concentrate from the cyclone overflow stream. A grade recovery relationship was established in the current test programme using a multiple pass approach on a batch basis. The relationship was very clear and indicates a mass pull of 2.5% would result in a gold recovery of approximately 75%. A conservative approach has been taken in sizing the gravity concentrators and subsequent fine grinding equipment. Additional testwork will provide an opportunity to further optimise these selections. In particular this may result in the inclusion of a small secondary concentrator operating in a cleaner mode, while reducing the fine grinding requirements with a smaller, higher grade concentrate.

Gravity Concentrate Comminution

Testwork to determine the gravity concentrate milling specific energy has not been completed due to time and sample limitations. A conservative milling specific energy has been assumed for the purposes of the design. If the specific energy requirement is less than the conservative estimate, there is opportunity to reduce the project capital and operating cost. Alternatively a larger gravity concentrate mass could be collected with an opportunity for increased plant gold recoveries for some ores. Fine grinding mill vendor testwork on a gravity concentrate sample to provide this data is likely to improve project economics.

Plant Recoveries

Plant recoveries for the transition ores do not include fine grinding of the gravity concentrate prior to leaching as this flowsheet was not trialled on the transition ores due to the typically high recoveries achieved without further grinding. There is an opportunity that the plant recovery for the moderately oxidised transition ores will increase when processed with the selected flowsheet.

The plant recoveries estimated for the minority Houndé primary ores (i.e. other than Vindaloo) have been based on higher mass pull gravity concentrates. There is a risk that the recoveries may be reduced at the lower plant design gravity mass pulls, although this risk is minimised by the minor proportion that these ores constitute and the possibility that a higher concentrate mass pull may be able to be treated as a conservative concentrate milling specific energy has been selected.

The plant recoveries have been estimated based on the leaching testwork 24 hour extractions. The plant CIL design allows for 36 hours leaching residence time and there is opportunity for higher plant gold recoveries than nominated.

Reagent Optimisation

The concentrate leach cyanide consumption was based on a high leaching concentration of 0.2% NaCN w/w (2000 ppm). There is an opportunity to optimise the plant concentrate leach cyanide concentration, thereby reducing the overall cyanide consumption and operating cost.

14.0 MINERAL RESOURCE ESTIMATE

14.1 Introduction

The updated Mineral Resource estimate for the Vindaloo deposits was completed by Cube in June 2013. This estimate represents an update of the Mineral Resources previously reported in the March 2013 PEA.

The work was completed under the supervision of Mark Zammit BSc(Hons) GradCertGeostats GradDipBus MAIG.

The aims of the June 2013 resource estimation were:

� Update the gold mineralisation interpretation for the Vindaloo deposits;

� Update the estimation of the gold grade within the Vindaloo deposits; and

� Update the Mineral Resource classification.

All estimation work was carried out using SURPAC mining software and Isatis geostatistical software. Grade interpolation for gold has used Ordinary Block Kriging (OK) of downhole composite drill data.

14.2 Previous Resource Estimate

The previous Mineral Resource estimate for the Vindaloo deposits reported in the March 2013 PEA contained 1,456,000 oz. Au in the Indicted category and 752,000 oz. Au in the Inferred category. This Mineral Resource was reported inside an optimised pit shell and above a cut-off of 0.35 g/t Au.

14.4 Geological Interpretation and Modelling

14.4.1 Lithology

The local lithological interpretation was provided by Endeavour geological staff based on geological logging and validated by Cube. The interpretation polylines were based mainly on 25 m spaced sections and included some 50 m spaced sections at the northern end of the project area. The polylines were snapped to drilling in most instances and creation of valid 3 dimensional solids (3DM’s) was not possible. Cube modified the interpretation by removing the snapped interpretation in the majority of instances by translating the polyline interpretation points onto section lines. This method honours the initial Endeavour interpretation but also enabled the creation of valid 3DM’s. The final lithology 3DM’s were used for direct assignment of lithology into the block model. The lithological interpretation, 3DM files and block model assignment is summarised in Table 14.4.1.

14.4.2 Weathering Domains

The weathering interpretation was provided by Endeavour geological staff based on geological logging, reviewed on site by Cube and accepted by Cube. One file was provided that included 3 surfaces to represent the overburden, saprolite, transition and fresh weathering domains. Cube split the single file containing the 3 surfaces into 3 individual files and expanded the perimeter of each to cover the block model area.

The final weathering interpretation files and method for block model assignment is summarised in Table 14.4.2.

14.4.3 Mineralisation Domains

The initial mineralisation domains were provided to Cube by Endeavour geological staff and subsequently modified by Cube in order to complete the mineral resource estimate. The interpretations were completed on 25 m spaced sections south of 1262950N and 50 m spaced sections north of 1262950N. The interpretations were based on local geological knowledge and typically were focussed on grades greater than 0.5 g/t Au.

Cube modified the interpretations mainly by allowing the interpretation to include mineralisation greater than 0.3 g/t Au rather than 0.5 g/t Au. This cut-off grade change resulted in a more robust interpretation with better domain continuity down dip and along strike, with some lower grade material being included as internal dilution to preserve overall continuity of the mineralised zones. The original Endeavour interpretation for the mineralisation was therefore based on grade and geological continuity within or parallel to steeply dipping gabbro intrusions. The interpretation updated by Cube was an attempt to encompass a greater part of the mineralised distribution and produce a model that reduces the risk of conditional bias that could be introduced where the constraining interpretation and data selection is based on a significantly higher grade than the natural geological lower cut-off. The revised interpretation was reviewed by Endeavour with a goal of keeping the focus on modelling mineralisation that has a better chance of being economic. The final modification to the interpretation was the inclusion of some minor flatter west dipping domains that are likely to represent linking structures.

Cube completed a boundary analysis for the larger domains and graphs for domains 2 and 17 are shown in Figure 14.4.1 and Figure 14.4.2 respectively. Both graphs clearly show an abrupt grade change at the interpreted boundary position (position 0 on the horizontal axis) with average grades inside the domain boundary significantly higher than the average grades outside. This suggests the absence of any obvious diffuse grade boundary and confirms the interpreted boundary position as appropriate.

On each section, the interpreted polylines were snapped to the drill hole sample positions. A minimum down-hole length of 1 m was used with the interpreted domains rarely less than 2 m down-hole. For each section the interpretation was not typically extended more than 50 m along strike or down-dip past the last drill hole. However, sectional interpretations were extended further than 50 m on some sections in some sparsely sampled areas of the better defined and continuous domains.

The final interpretation that included 39 domains was reviewed by Endeavour geological staff. The 39 domains which collectively make up Vindaloo deposits have been grouped into 4 main areas which include Vindaloo Main, Vindaloo North-East, Vindaloo 2 and Madras North-West and are summarised below in Table 14.4.3.

14.4.4 Bulk Density

All available bulk density data was supplied to Cube by Endeavour and included a total of 2,785 determinations. Cube reviewed the determinations and methodology used for specific gravity. The determinations that were deemed acceptable were limited to measurements undertaken on diamond drill core which had been wax coated and measured using a standard water displacement method. This resulted in a total of 2,241 determinations available for inclusion in the resource estimation. The remaining 544 density determinations were measured by pychnometer or by unknown means and not considered appropriate or reliable and therefore excluded from the final data set. The determinations that were accepted were imported into the database “HoundeUpdate_20130507.mdb” and an additional field called “use_in_resource” was created. The determinations deemed by Cube as appropriate for use in the resource were flagged as “Y”.

All of the bulk density determinations suitable for resource estimation were exported from the database. They were grouped according to the logged lithology type and oxidation state to form the basis for assignment of in-situ bulk density to the Vindaloo deposits. Table 14.4.4 summarises the mean of the density determinations by weathering and lithology. The number of determinations for each lithology is shown in brackets.

Table 14.4.5 summarises the values used to assign bulk densities to the block model based on “weathering” and “lithology”. For the overburden and saprolite, the mean density values have been discounted slightly to allow for sampling bias often encountered in determination data populations for more friable and unconsolidated material.

Fresh 2.74 2.78 2.67 2.67 2.74

14.5 Compositing

In the drill hole database, a unique code for drill intercepts within each of the mineralised domains was added to the database table called ZONECODE. The process of coding the database was carried out by manually identifying the appropriate down hole interval to be coded and assigning a unique code according to the enclosing domain wireframe. This coded interval was used to control the compositing process.

Assay sample lengths varied from 0.19 metres to 9.00 metres with the mean length of 1.06 metres and median of 1.00 metre. To ensure equal sample support, Cube decided that 1 metre downhole composites were appropriate for all compositing within the mineralised domains. The downhole compositing process used a ‘best fit’ approach which results in composites of slightly variable length but of equal length within a contiguous drill hole intersection, ensuring the composite length is as close as possible to the nominated 1 metre composite length.

Variography has been used to analyse the spatial continuity within the mineralised zones and to determine appropriate estimation inputs to the interpolation process. The variogram modelling process followed by Cube involves the following steps:

� Calculate and model the omni-directional or down hole variogram to characterise the Nugget Effect;

� Systematically calculate orientated variograms in 3 dimensions to identify the plane of greatest continuity; and

� Calculate a fan of variograms within the plane of greatest continuity to identify the direction of maximum continuity within the plane. Model the variogram in the direction of maximum continuity and the orthogonal directions.

Variography was undertaken on Gaussian transformed 1 metre down hole high cut composite data. The Gaussian transformation was modelled in Isatis on the declustered 1 m composite data. The Gaussian variogram model was back transformed and modelled to obtain the appropriate variogram model for interpolation of raw composite data.

Variogram parameters were derived for the two most sampled mineralisation domains (2 and 17) within project area. Variogram modelling for the more sparsely sampled domains was difficult and not considered appropriate for use as the number of composite samples was limited. The modelled variograms for domains 2 and 17 showed very similar characteristics and therefore Cube decided to adopt the variogram parameters for domain 2 to all other mineralised domains within the project area. Where variogram parameters have been adopted to adjacent mineralised domains, directions and anisotropy ratios have been modified to best suit the geometry of the domain under consideration. Cube believes that this is a reasonable approach and open to update when the drilling density is sufficient for robust individual variogram parameters to be established.

Variogram relative nugget effects were typically in the range of 50 - 60% indicating a moderate to high degree of short scale variability as would be expected in gold deposits. Variogram ranges were typically in the order of 50 - 60 metres indicating maximum spatial continuity is greater than the average drill hole spacing.

No plunge component was evident during the variogram modelling process.

Table 14.6.4 below summarises the raw variogram parameters and Table 14.6.5 summarises the relative variogram parameters used in the mineral resource estimation. Figure 14.6.7 and Figure 14.6.8 represent the Gaussian transformed and back transformed variogram models respectively for Domain 2.

14.7 Evaluation of Outliers

Cube reviewed the statistics of the composites to check for outlier composite grades prior to estimation. The composite data was reviewed using histograms, log-histograms, log-probability plots, high grade sensitivity analysis and graphical inspection of the spatial grade distribution. The composite data was reviewed for each individual domain and by weathering. The results showed that there was no requirement to separate the composite assay population treatment by weathering and a top cut of 40 g/t Au was determined to be appropriate for the total composite population. Log probability and histogram plots for the combined 1m composites are shown in Figure 14.7.1 and Figure 14.7.2 and separated by weathering in Figure 14.7.3.

Basic statistics for the cut gold composites were calculated for each of the 39 domains. The basic statistics for each domain is shown below in Table 14.7.1 to Table 14.7.3. Included in the summary statistics for the top cut composites is the declustered mean based on a 50(N) x 10(X) x 50(Z) cell size.

14.8 Block Model Set Up

A number of criteria were considered when setting up the block model. Given the overall trend of mineralisation is striking toward 0310, it was decided a rotated block model oriented parallel to the strike direction would be most appropriate. Data spacing was a primary consideration taken into account when selecting the appropriate estimation block size. The drill hole spacing within the mineralised zones was reasonably regular and dominated by drilling on 25 m and 50 m spaced sections with 25 m and 50 m spaced holes on section. Cube considers it good geostatistical practice to use an estimation parent cell size that approaches the data spacing where possible, while at the same time being mindful of potential mine design and selectivity implications. Cube reviewed the ‘physical’ data spacing relative to the mineralised zones to be estimated when deciding on the appropriate estimation block size. Cube decided that an estimation parent block size smaller than 10m(Y) x 5m(X) x 10m(Z) would result in excessive smoothing of the estimate which is symptomatic of extreme conditional bias. A smaller block size would result in increased kriging variance and potentially reduce the quality of the mineral resource estimation. Sub-blocking to 2.5m(Y) x 1.25m(X) x 2.5m(Z), has been used to improve the volume representation of the block model.

Two 3D block models were created using Surpac 6.3 software. The first was used for grade estimation with the model architecture described above and summarised in Table 14.8.1. The second and final block model was created with a smaller parent cell in the “Z” direction. This resulted in a smaller model file size that was easier to manipulate. The grade estimate was exported from the initial estimation model and imported into the final model called “hounde_june2013.mdl” which summarised in Table 14.8.2. The block model attributes and descriptions are summarised in Table 14.8.3.

14.9 Block Model Grade Estimation

Grade interpolation was carried out using Ordinary Kriging (OK) for each mineralised domain using the uniquely coded 1 metre down hole composite data specific to that domain. All block estimates were based on grade interpolation into parent cells of 10m(Y) x 5m(X) x 10m(Z). Block discretisation points were set to 4(Y) x 2(X) x 2(Z).

Cube has attempted to characterise the spatial relationship of the data using variography and has sought to implement search strategies aimed at producing a robust block estimate whilst at the same time minimising estimation error and conditional biases. Cube routinely tests several search iterations before determining the most appropriate search strategy. Fundamental to the search strategy is the determination of appropriate minimum and maximum numbers of composites for estimation. The minimum number of composites has been considered by Cube as a key component of the criteria applied in determining the appropriate resource classification.

Cube initially bases search distances for the first search iteration on the analysis of the theoretical kriging weight charts. An examination of these kriging weight charts provides a good starting point for testing a search strategy as they provide a guide as to the distribution of kriging weights for a given variogram with respect to distance along the major axis of the search volume. Of particular interest is the approximate distance that kriging weights tend towards zero. Cube believes that it good estimation practice to use a search distance that ensures that kriging weights allocated to composites tend toward zero or slightly negative on the periphery of the search.

Cube generally extends the search where there are large positive weights at the periphery and reduces the search where there are a large proportion of negative kriging weights involved. A limitation of these charts is that they are based on an assumption that each block is directly informed by a composite at the block centroid and they will, therefore generally understate the required search with respect to actual data spacing to achieve a robust block estimate.

A Quantitative Kriging Neighbourhood Analysis (QKNA) was undertaken to assist in optimising the search parameters.

The procedure for search optimisation adopted by Cube involves selecting several individual blocks representing data configurations ranging from poorly to well informed. The aim of these tests is to optimise the kriging search neighbourhood and maximise the quality of the kriging when dealing with a non-exhaustive data set. A number of key criteria were captured for each selected block as follows:

� Block coordinates and dimensions;

� Estimated grade;

� Kriging variance;

� Block Dispersion variance;

� Slope of Regression of estimated blocks z*(v) and theoretical true blocks z(v);

� A listing of the actual informing composites within the search volume of the block including coordinates, grades, distance from block and kriging weight; and

� Statistics of the informing composites including number of composites, minimum, maximum, mean, standard deviation, variance and coefficient of variation.

An important feature of Ordinary Kriging is its inherent property to minimise estimation error. The estimation error will increase substantially as the amount of informing data decreases.

Based on the QKNA and visual analysis of the samples selected under OK, appropriate search parameters were chosen and are detailed below in Table 14.9.1. Search ellipse orientations for each domain interpolation were orientated to follow the direction of the mineralised domain. A two pass search strategy was used for grade estimation. The first pass search used a search radius of 75 m and this was doubled for the second search pass to 150 m. The same minimum (6) and maximum (40) number of samples were used for both search passes. Appendix 14.1 tabulates the complete estimation parameters used for each domain.

14.9.1 Treatment for Un-estimated Blocks

A small proportion of blocks for Domain 18 only did not satisfy the minimum criteria for grade estimation. The volume of these blocks represented 3.3% of that domain and less than 0.1% of the total volume. These blocks remained un-estimated and not included with the Mineral Resource.

14.10 Model Validation

Modelled estimates within the domains have been compared with the down hole composite grades in a number of ways. Initially a visual validation was undertaken on screen comparing the block estimates with the composite data in cross section. The estimates honoured the composite data well with some degree of grade smoothing of the block estimates as would be expected from Ordinary Kriging.

The mean block estimate for each domain was also compared to the mean composite grade of the corresponding domain (Table 14.10.1). Although these two parameters are not strictly comparable due to data clustering and volume influences, they do provide a useful validation tool in detecting any major biases and allow the comparison between input composite grade and the estimated block grade. The global comparisons for gold indicate good agreement between composites and estimates throughout the majority of the project. Locally areas of deviation occur but these are generally the result of data clustering.

Swath plots (grade trend profiles) showing the estimated tonnes, estimated grade, number of composites and mean cut composite grade (tabulated by northing and RL) were created for the largest 20 interpolated mineralisation domains (Appendix 14.2). The limitations of this comparison should be kept in mind when drawing conclusions; however there is generally good agreement between the block estimate and declustered composite mean for all domains. As expected, the estimated grade is more smoothed compared to the often variable composite mean grades. Figure 14.10.1 shows a swath plot for Domain 2 by 100 m northing intervals. The grade estimate appears to be lower compared to the composite means for the volume between 1261150N and 12611850N which corresponds with the largest tonnage proportions for that domain. The difference is explained by comparing 25 m RL interval data in a swath plot between 1261150N and 12611850N. The corresponding swath plot is displayed below in Figure 14.10.2 which shows a very close correlation between composite and estimate mean grades. Clustered high grade samples above 250 m RL are responsible for the discrepancy when comparing by northing.

A final validation involved a comparison of the OK estimate for both cut and uncut Au against two other estimation techniques being Inverse Distance Cubed (IDW3) and Nearest Neighbour (NN). Above a zero g/t Au cut-off, there is very good agreement between the three estimation techniques for both cut and uncut Au and this is summarised in Table 14.10.2.

14.11 Mineral Resource Classification

It is Cube’s opinion that the Vindaloo mineralisation is sufficiently drilled to allow classification in accordance with the CIM guidelines (CIM 2005). As with any non-rigidly defined classification there will always be some blocks within categories that depart from defined criteria. It is Cube’s view that the final outcome must reflect a practical combination of geological knowledge and estimation quality parameters that may be more numerical in nature. This approach to classification aims to avoid creating a complex numerically based ‘mosaic’. Cube has considered all criteria and has classified the resource accordingly. The classification supports the recommendations made in the PEA March 2013 which states “nominal 50 m x 50 m drill spacing for Indicated Mineral Resources and approximately 25 m x 25 m spacing for Measured Mineral Resource”.

The primary criterion for Measured Mineral Resources is defined by a drill spacing of at least 25 m x 25 m. In addition, Measured Mineral Resources were confined to the largest interpreted mineralisation domains that had the least amount of risk associated with geological interpretation and continuity. The only domains to include Measured Mineral Resources are 2, 3, 15, 17, 18 and 19.

A basic Conditional Simulation study was undertaken to provide supporting evidence for classification of the Measured Mineral Resources. Domain 2 was chosen for the study as it represents the largest and most continuous mineralised domain at Vindaloo. The results suggested that on a mining production quarterly basis the grade variance was within ±10% at a 90% confidence limit.

Indicated Mineral Resources are defined as areas outside the Measured Mineral Resource and defined by 50 m x 50 m drill spacing. As mentioned in Section 14.9, a 2 pass search strategy was used for grade estimation and the Indicated Mineral Resource is confined to blocks estimated within the first pass search.

Inferred Mineral Resources include all remaining estimated mineralisation defined either by a drill spacing greater than 50 m x 50 m or estimated within the second pass search .

14.12 Mineral Resource Statement

For the purpose of public reporting, the Vindaloo Mineral Resource is reported inside an optimised pit shell. Reporting within an optimised pit shell satisfies the requirement for the Mineral Resource to have reasonable prospects for future economic extraction. The pit optimisation was undertaken by Orelogy and assumed a US$1,600/oz Au price and an average mining cost of US$2.107/tonne; note that Orelogy estimated a higher mining cost per tonne than estimated in the PEA, resulting in the development of a shallower optimized open pit than was envisioned in the PEA. Table 14.12.1 to Table 14.12.3 summarise the economic parameters used.

15.0 MINERAL RESERVE ESTIMATES

15.1 Mining and Mineral Reserves Estimation Approach

Following the completion of the Preliminary Economic Assessment in March 2013 and subsequent studies and testwork, the Houndé open pit gold project development is proposed with:

� Construction of a new nominal 3.0 Mtpa process plant.

� Conventional mining methods utilising drilling, blasting, trucks and shovels.

� A general site layout as highlighted in Figure 15.1.1.

This section of the report includes discussion on the open pit optimization and practical pit design. The mineral reserves and the results of the mine design process are presented. Other items such as the scheduling process and equipment considerations are presented in the following section “Mining Methods” (Section 16) and mining cost estimates are included in the “Capital and Operating Costs” (Section 21).

The mine planning process for the reserve estimation comprised the following components:

� Whittle-4X pit optimisation software was used to identify the optimum pit shell in terms of value and tonnage using the parameters outlined below in this section.

� MineSight general mine planning software was used to develop practical stage designs to access the orebody.

� EVORELUTION scheduling software was used to develop strategic level schedules to determine a practical starting sequence that maximised net present value (NPV). This was then used as a guide to the subsequent detailed life-of-mine (LOM) schedule.

� Mining costs for the project, to be incorporated in the project financial cash flow model, were estimated based on the final design and associated LOM schedule.

The mining components of the study are based on the geological Mineral Resource block model generated by Cube Consulting Pty Ltd which encompasses the Vindaloo and Madras deposits. Mineral Reserves have been modified from Mineral Resources by taking into account geological, geotechnical, mining, processing, economic parameters and permitting requirements and therefore are classified in accordance with the Joint Ore Reserve Committee (JORC) 2012 standards and/or CIM Definition Standards for Mineral Resources and Mineral Reserves.

15.2 Pit Optimisation Key Assumptions / Basis of Estimate

Mineral Reserves for Vindaloo and Madras are supported by a LOM plan, which was developed using the following information and key parameters in the pit optimisation process.

15.2.1 Resource Model

The resource model is an Ordinary Kriged (OK) model developed by Cube Consulting and has a total of 39.6 Mt at 1.91 g/t Au at a 0 g/t Au cut-off grade. Over 87% of the resource is classified as Measured or Indicated with the remaining 13% classified as Inferred. Earlier sections of this report provide more background and detail on this resource estimate.

Throughout the mine planning process, only Measured and Indicated Mineral Resources are eligible to qualify as ore, all other mineralization, including Inferred Mineral Resources, have been classified as waste.

15.2.2 Geotechnical Considerations

Overall slopes were derived from the inter-ramp angles recommended by Peter O’Bryan and Associates, independent geotechnical consultants commissioned by Knight Piésold. These inter-ramp angles, and the associated wall design criteria, are detailed in Table 15.2.1.

ORELOGY utilised these parameters to develop the overall slopes for the optimisation. A first pass optimisation and design was undertaken to fully evaluate the combined effects of ramps, stack berms and shear zone double berms. The final wall slopes were developed for five areas of the deposit. The final slopes used are detailed in Table 15.2.2 and the associated areas shown in Figure 15.2.1.

15.2.3 Ore Loss and Dilution

The approach to determine ore loss and dilution is based on the following deposit characteristics and mining practices:

� The sub-vertical nature of the mineralised zones.

� The ability to visually distinguish between mineralised and barren materials when defining and subsequently excavating the ore / waste boundaries.

� Adherence to the correct blasting free face orientation, perpendicular to the strike of the mineralisation.

� Adoption of 5 metre high benches, with the option to excavate 2½ metre high flitches if required.

Due to these control mechanisms ORELOGY estimates that the amount of mixing at ore waste boundaries should be limited to a 1 m wide zone only. This approach has been applied to the Resource Model to produce a Diluted Mining Model incorporating dilution and ore losses. This results in average values for dilution and ore loss within the Measured / Indicated orebody of 6.5% and 5.2% respectively.

The resulting model incorporating dilution and ore loss is referred to as the Mining Model, as opposed to the Resource Model.

15.2.4 Optimisation Mining Costs

Table 15.2.3 details the general material properties used in the development of the first principle mining costs. The densities were obtained from the resource model default settings, the moisture contents were adopted in consultation with Endeavour and the swell factors are engineering estimates based on ORELOGY experience. The swell factors were used for calculating equipment capacity limits.

The fleet that was used for developing the optimisation mining costs was based around a Caterpillar 785 140 tonne truck matched to a Caterpillar 6040 390 tonne excavator. This equipment was selected on the basis that these machines are:

� Fit for purpose (i.e. capable of mining both the 5 metre bench height and the 2½ metre flitch height.

� Able to deliver the dilution and ore loss outcomes in accordance with the modelling described above without any significant loss of productivity assumptions.

It is acknowledged that the Caterpillar 6040 is, in reality, a larger machine than would be suitable. At the cost estimation phase of the study this unit was replaced with a smaller 6030 290 tonne unit. The net result of this selection was actually a reduction in loading costs as the 6040 had been de-rated to match the 140 tonne trucks (refer to the shovel productivity calculations detailed in Table 15.2.4). Consequently the optimisation costs can be considered conservative.

For the purposes of generating a realistic LOM mining cost, haulage costs were developed within the block model and flagged into a number of different zones as highlighted in Figure 15.2.2 for the application of the loading and hauling costs. Regressions were then developed and used to code the block model with these costs on a bench by bench as well as pit by pit basis.

Drill and blast costs were developed from first principles. The key underlying assumptions are:

� 2 x 5 metre high bench height to give a total bench height of 10 metres for drill and blast purposes.

� Powder factors for the different material types are ORELOGY engineering estimates.

� Drill penetration rates are ORELOGY engineering estimates incorporating Endeavour actual drilling rate feedback.

Bench height and powder factors drive the drilling and blasting design parameters such as burden and spacing. The drill penetration rate together with the burden, spacing and bench height yield the drilling productivity. This is summarised in Table 15.2.5.

The other key assumptions are:

� Any hard, lateritic overburden or “caprock” does not require blasting and can be “ripped” by a dozer if required.

� 80% of saprolitic clays will not require blasting and can be mined by “free digging”.

Table 15.2.6 below shows the resulting production drill and blast costs developed from first principle calculations. Note that the pre-splitting cost has only been applied to the fresh waste.

It has been assumed 0.3 metres of topsoil covers the entire site. All pit, waste storage facility (WSF), haul road and infrastructure areas will require clearing of vegetation and stripping of topsoil. The topsoil requires storage and subsequent rehandle for rehabilitation of all disturbed areas. In reality there will probably be little, if any, revegetation of the pits. However some costs will be incurred to leave the site in a safe state when operations cease and the pits are abandoned. The material stripped from the pits will most likely be utilised in the final WSF landforms.

Activity Unit Rate

Total Clearing and Rehabilitation $/Ha $6,750

Topsoil replacement and spreading $/Ha $7,400 Rehabilitation and Land forming (WSF) $/Ha $1,500

The cost per tonne for WSF clearing and rehabilitation was based on the tonnes of placed material per square metre over a WSF height of 50 metres. The resulting costs per tonne are detailed in Table15.2.8.

For the purposes of the optimisation cost estimate, it was assumed ore grade control would be carried out using reverse-circulation (RC) drilling in advance of mining. It was based on a drill pattern of 25 m x 25 m and the waste was drilled at the ratio of 1 tonne of waste per tonne of ore drilled. Hole inclination was 50° over 4 x 5 m benches (i.e. 20 m vertically giving a 32 m hole length). An inclusive contract drilling rate of $45/m drilled was assumed and that sampling was carried out every two metres. A $/t cost as detailed in Table 15.2.9 was then generated.

It has been assumed that 80% of the ore mined will be direct tipped to the crusher. The other 20% will be stockpiled on the RoM pad at the primary crusher and require rehandling with a loader. Productivity and costs are detailed in Table 15.2.10 on the basis of a Caterpillar 992K FEL tramming an average of 100 m one way.

All Endeavour fixed costs are summarised in Table 15.2.11.

Total $6,221,500

All Endeavour variable personnel costs (i.e. operators and maintenance personnel) are allocated as part of the hourly cost of operating the equipment.

All costs outlined above were allocated to the mining block model. To provide a sense of the magnitude of the ore and waste mining costs for fresh, transition, saprolite and overburden materials Figure 15.2.3 and Figure 15.2.4 show the weighted average across all pits varying with RL.

In general as the pit depth increases, mining costs rise because of longer haulage distances and higher drill and blasting costs associated with fresh rock below the transition and saprolite materials.

The ore mining costs are higher than the waste mining costs because:

� Drilling and blasting costs of ore are higher (Table 15.2.6).

� Grade control costs (Table 15.2.9) are allocated to ore only.

� Only ore attracts rehandling costs (Table 15.2.10).

� Fixed costs (Table 15.2.11) are allocated to ore.

Shell 30 was selected for subsequent pit designs and scheduling as it provided an acceptable balance between minelife and costs in line with Endeavour’s objectives to establish a profitable, low cost, operation. A longer minelife provides for more revenue but it also results in higher stripping ratios and hence higher costs, and vice versa. The cashflow of Shell 30 at $900M is 0.5% lower than that of Shell 36, the shell with the highest cashflow, while the mining and processing costs at $882.7M are 7.1% lower.

Shell 30, having a revenue factor of 0.88, provides for a minelife of 8.3 years, including pre-strip, and a stripping ratio of 8.5. The inventory of Shell 30 is summarised in Table 15.3.2.

15.3.2 Optimisation Sensitivity

A sensitivity analysis was undertaken to determine the sensitivity of the project to changes in the optimisation inputs. The figures below display the % variation in a number of Key Sensitivity Outputs (KSOs) for a variation in an Optimisation Input Parameter (OIP). The Ore Tonnage KSO sensitivity shown in Figure 15.3.2 indicates the robustness of the shell, and hence the pit design. The sensitivity of the Project Discounted Cashflow KSO is highlighted in Figure 15.3.2. It shows sensitivity to both wall slope angle and grade, and a high sensitivity to gold price. This is not an uncommon result for an open pit gold project as gold price and grade directly affect revenue.

Ore tonnes sensitivity:

� The project is highly sensitive to a reduction in price but only slightly sensitive to an increase in price. This indicates that the pit shell and therefore associated pit design will not increase significantly should price increase and that the ultimate pit extent will be relatively robust.

� Variations in grade and process recovery are effectively equivalent. As with price, the shell is more sensitive to reductions in grade / recovery than increases.

� The shell is insensitive to variations in processing cost, slightly sensitive to variations in mining cost, and sensitive to variations in the combined costs.

� It is sensitive to variations in slope angles.

� A sensitivity analysis was also run on applying a global 15% dilution and 0% ore loss. As expected, this indicated that ore tonnes were sensitive to this parameter combination, and therefore dilution should be accepted in order to minimise ore loss.

Cashflow sensitivity:

� The project value is highly sensitive to parameters that directly affect revenue (i.e. price / grade / recovery).

� Project value shows the same sensitivity to the other parameters as the ore tonnes displays.

� The 15% dilution / 0% ore loss sensitivity has a marginal positive impact on DCF.

� Overall this indicates the Houndé Project is sensitive to optimisation parameters, with price / grade / recovery being the main major sensitivities.

15.3.3 Risk Management

As with most gold projects, the Houndé Project is most sensitive to those parameters that directly affect revenue, in particular, the gold price, processing recovery and the grade of the ore. Therefore any practices that can result in fixing these parameters at a feasible level (e.g. gold hedging) should be investigated to determine if, where necessary, project risk can be reduced.

There will be a degree of flexibility built into both the pit designs and schedules based around Shell 30 to mitigate against any future variations in economic parameters. For example:

� The main Vindaloo pit will be developed as smaller, interim stage designs that focus on the high value ends of the pits. This will defer the establishment of the more sensitive areas of final pit wall so that economic parameters can be re-assessed and the final wall adjusted if necessary.

� The small northern pits are relatively marginal and generate little significant value. Therefore they will be scheduled late in the mine life such that they can be “dropped off” should conditions deteriorate or more attractive deposits be identified.

The sensitivity study results also indicate that while there are the usual cashflow benefits associated with decreasing costs, the project is more susceptible to the adverse effects of increasing costs than any benefit of equivalent cost reductions. Therefore robust cost estimation and rigorous operating practices are required in order to maintain an on-going cost regime driving low cost outcomes.

15.4 Mine Design Process

Pits were designed using MineSight mine planning software, and utilised the MiningModel, the pit optimisation results (Shell 30) and application of the pit design criteria outlined in Sections 15.5.1 as guides. The results of the pit design process were then exported to EVORELUTION, the ORELOGY proprietary mine scheduling software, for scheduling and reporting of the mineral reserves.

Global “waste storage shells” were developed in MineSight at the waste storage facility locations shown in Figure 15.1 1. A waste storage shell is a space to which waste may be allocated in the mine scheduling process, and is designed in accordance with waste storage facility design criteria provided in Section 15.7. These shells were then also exported to EVORELUTION where they are used to develop a waste storage facility model. Determination of the waste haulage is calculated on the basis of minimising haulage costs as each block is mined from the pit and then “placed” within the waste storage model. Hence the final waste storage facility geometry is optimised by the EVORELUTION scheduling software, while remaining faithful to the dump design guidelines.

The results of this process are provided below.

15.5 Pit Design

15.5.1 Design Criteria

Slope design criteria, as summarised in Table 15.2.2 Final Optimisation – Overall Slope Angles were supplied by Peter O’Bryan and Associates.

The ramp design criteria, summarised in Table 15.5.1, are based on the 143 tonne payload Caterpillar 785D dump truck. The 785D has a total operating width of 7.1 metres and has a machine clearance turning diameter of approximately 33 metres.

It is common industry practice to design the width of the main ramps at 3.5 times truck width and adopting a 10% gradient. This allows for safe passing of trucks inclusive of wall side drainage and pit side bunding. The two-way ramp width used for the designs in Vindaloo Main was 25 metres, which equates to 3.5 times the 785D operating width. 15 metre wide single lane ramps (approximately 2 times the truck width) were used in Vindaloo 1, Vindaloo 2 and the Madras pits from the surface all the way to the bottom of the pit in order to minimise waste mining and hence costs.

For the benches at the pit base (i.e. the bottom 30 – 40 vertical metres), a single lane ramp width of 15 m with a maximum gradient of 12.5% was allowed. This reflects the lower traffic intensity on this section of the ramp and allows waste development to be minimised.

Table 15.5.1 Ramp Design Criteria

Pit Lanes Width (m)

Maximum Grade (%)

Vindaloo Main Dual 25 10 Vindaloo 1 & 2 and Madras Single 15 10 All pits – Bottom Section Single 15 12.5

Switchbacks are to be located on flat sections of ramp. The switchback centreline turning diameter equals 39 metres which equates to 1.5 times the truck centreline turning diameter.

Pit designs, whether they are final or interim stage designs, need to provide sufficient space to undertake mining activities in an efficient and safe manner. This applies to the bottom of each stage / ultimate pit design and also to pushbacks. Providing sufficient space is achieved by adopting a minimum mining width in the design criteria.

A minimum mining width of 55 m has been adopted. This distance is based on loading machine clearance turning diameter of 20 m, plus 15 m clearance on both sides plus a 5 m windrow. This will allow a truck to turn around on the bench with ease, provide sufficient space at the truck loading areas, space for jump up access for drilling and blasting activities and space for bunding and drainage.

A narrower width of 14 m has been allowed for the final “goodbye” drop cut at the very base of the pits. Goodbye cuts, targeting ore material only, are mined from a pit floor with permanent ramp access and a minimum mining width of approximately 20 m to 25 m. Goodbye cuts are excavated with a backhoe and there is no access to the bottom of these cuts.

The location of the pit exits is important to minimise the ore and waste haulage costs. The overall stripping ratio from the pit optimisation process equals 8.5, this means the waste volume is much larger than the ore volume and hence the pit exits need to be located such that the waste haulage is minimised.

The design of the Vindaloo and Madras pits are shown in Figure 15.5.1 to Figure 15.5.15. Also shown in these figures are the diluted ore grades of the measured and indicated materials, the optimisation shell, surface topography, bottom of the oxidation (BOCO), top of fresh rock (TOFR) and locations of the shear zone.

15.5.2 Vindaloo Main Ultimate Pit Designs

Due to the presence of a shear in the western wall of the Vindaloo Main South pit and because the relative long period of time over which this pit is being mined, the ramp was located in the eastern wall to avoid any pit access interruptions.

15.6 Houndé Mineral Reserves Calculation

Mineral Reserves are quoted within specific pit designs based on Measured and Indicated Mineral Resources only and take into consideration the mining, processing, metallurgical, economic and infrastructure modifying factors. Preparations to submit information for environmental approvals and mining lease applications have commenced.

This reserve estimate has been determined and reported in accordance with Canadian National Instrument 43-101, ‘Standards of Disclosure for Mineral Projects’ of June 2011 (the Instrument) and the Definition Standards adopted by CIM Council in November 2010.

At a net gold price of $1218.24 per ounce (Table 15.2.14), the cut-off grade for the mineral reserves varies by location on the basis of the processing costs detailed in Table 15.2.12, the processing recoveries detailed in Table 15.2.13, and the ore related mining costs which vary block by block. Therefore the global weighted cut-off grades by pit are shown in Table 15.6.1 as an indication of the cut-off grades used for reporting.

15.7 Stage Designs

Stage designs were generated for Vindaloo Main in order to enhance the scheduling process aiming to delay waste mining as much as practically possible and to bring forward higher grade ore; and/or ore with lower mining costs due to shorter haulage distances; and more weathered ore with lower processing costs.

Multiple stages were designed for Vindaloo Main. The other deposits are too small for more than a single stage. The Vindaloo Main stage designs are shown in Figure 15.7.1 to Figure 15.7.5.

The mineral reserves in each of the stages is summarised in Table 15.7.1.

Vindaloo Main stages 11, 12 and 15 can be mined independently and are good starter pits with favourable stripping ratios and with average grade or better. For this reason it is better to mine Stage 13 after Stages 11 and 12. Stage 14 must be mined in conjunction with Stage 13 in order to maintain ramp access; it can lag behind Stage 13 by no more than 4 benches.

Stage 16 can be mined after Stage 15 or in conjunction with it. Stage 16 is a better stage than the Stage 13 and Stage 14 combination because it has a higher grade and lower stripping ratio.

The other pits can be mined independently but Vindaloo 1 and the Madras pits have relatively low stripping ratios but also below average gold grade. Vindaloo 2 has a high gold grade but also has a high stripping ratio.

The stripping ratio and grade trade-offs are determined in the scheduling process described in Section 16 of this report.

15.8 Waste Storage Facility Designs

Waste storage facility shells have been designed with the following design criteria:

� The standoff distance between the pits and the waste storage facilities has been determined in accordance with safety bund requirements by the Department of Industry and Resources of Western Australia as illustrated in Figure 15.8.1. The position of the WSF toe is located at the toe of the safety bund.

Figure 15.8.1 WSF Standoff Distance from Pit Crest

� In order to realise cost savings now, rather than a potential cost saving at some point in the future it, was decided to allow the eastern WSF to be constructed on the Koho mineralisation zone.

� There was no maximum height limit for waste storage facilities.

� The swell factor utilised to calculate the placed material in the waste storage facility was 25%.

� The overall final landform angles are 20 degrees.

� No consideration was given to stand off distances between WSFs and villages or heritage sites as there do not appear to be any villages or heritage sites in the vicinity of the mining.

The shells were exported to EVORELUTION scheduling software. As the schedule progresses, the shells are filled with waste. The waste destination is determined by the lowest cost haulage option available. Hence the volumes and the final shapes of the waste WSFs are determined and optimised during the scheduling process.

In reality WSFs are constructed in 20 m high lifts with 37 degree face angles and are later reworked into their final landform during the WSF rehabilitation process. This is illustrated in Figure 15.8.2.

16.0 MINING METHODS

16.1 Mining Method

16.1.1 General Description Mining Methods

The PEA demonstrated that the Vindaloo and Madras deposits are suitable to conventional open pit mining methods adopting drilling, blasting, trucks and shovels in order to supply ore to a 3 Mtpa treatment plant.

The optimisation process described in Section 15 validates adopting these conventional open pit mining methods for the development of the Houndé project. This study has adopted 5 m high benches in ore and 10 m high benches in bulk waste in order to avoid, as much as practical, ore loss and dilution during the mining process. The optimisation process described in Section 15 also highlights the importance of adopting grade control methods that minimise the effect of ore loss and dilution during the mining process.

After initial detailed cost comparisons between submissions from mining contractors and first principle owner / operator mining costs, the “Owner Operator” option approach was used as the go-forward option in this study. Only two mining service contracts are anticipated:

1. The supply of “down the hole” blasting service which includes both the delivery of bulk explosive “down the hole” and the supply of blasting accessories.

2. RC drilling for grade control.

16.1.2 Mining Equipment

The equipment planned for the Houndé project is summarised in Table 16.1.1 and Table 16.1.2.

The fleet was based around a 140 tonne capacity Caterpillar 785 rigid bodied dump truck matched to a Caterpillar 6030 excavator (290 tonne). This equipment was selected on the basis that these machines are:

� Fit for purpose (i.e. capable of mining both the 5 metre bench height and the 2.5 metre flitch height).

� Able to deliver the estimated dilution and ore loss without any significant loss of productivity.

16.1.3 Blasting

Blasting will be undertaken utilising industry standard storage, transport and charging practices for a modern mining operation, subject to all local and national statutory and regulatory requirements.

Mining operations are not adjacent to villages or public roads. With exception of the Madras pits the processing plant and other infrastructure associated with the project are at a distance in excess of 500 m from the pits. The crest of the Madras South pit is at a distance of 260 m from the 225 kV Cote d’Ivoire – Burkina Faso power line. Blasting is not currently required at Madras Pit. However should blasting be required in the future it needs to be executed carefully to avoid interference with the operation of this power line.

1813.20\25.01\1813.20-STY-001_B S16

Page 16.3

October 2013 Orelogy Pty Ltd

At the start of blasting operations it is planned to measure the blasting induced vibration levels at the power line to confirm that these levels are negligible and will not interfere with the operation of this line.

16.1.4 Mine Dewatering

Water inflows resulting from rainfall and from ground water into the pits will be collected in pit sumps. Sump pumps will transfer this water into water carts being used for dust suppression or into the “Turkeys Nest” pond on the surface if there is more water than needed for dust suppression. The Turkeys Nest is connected to the water management system of the processing plant and excess mine water will be absorbed by this system.

The general drainage in the project area is towards the south east. It has been indicated that the catchment areas are relatively small and the average rainfall is also relatively low at 226 mm for August, the wettest month.

None of the pits are immune to the surface water inflow without the protection of a small cut-off bund around the pit crest. These bunds are also needed to prevent people inadvertently gaining access to the pit crest with vehicles. Construction of bunds with waste material is addressed during the mining phase without incurring extra costs (i.e. instead of this material being dumped on the waste storage facility it is placed around the pit edge at no additional cost).

The Vindaloo 2 pit intersects one of the natural drainage channels running north of this pit and an engineered diversion has been generated to avoid flooding of this pit. This civil engineering solution is not part of the mining scope and this work was undertaken by Knight Piésold.

16.1.5 Dust Suppression

Dust suppression will be undertaken by water carts fitted with spray bars. Water for dust suppression will be available from sumps in the pits in first instance and from the Turkeys Nest on the surface if the pit sumps run dry.

16.1.6 Grade Control

The grade control approach during optimisation was based on blast holes. However, this has changed as it is intended to adopt RC drilling techniques as the basis for grade control in order to provide better coverage of the ore zones. Samples are planned to be taken every 2 metres over a 32 metre deep inclined (50°) hole. The grade control pattern across the ore is factored by 100% to account for the drilling of the surrounding waste (i.e. a ratio of 1 waste tonne for every ore tonne drilled). A pattern size of 25 metres along strike and 15 metres across strike is planned. It is intended to undertake this activity using contract drilling.

The samples will be collected by geology personnel and delivered to the site lab. Assay results will be used for grade control modelling and reconciliation, eventually feeding back into the resource modelling and mine planning.

16.1.7 Mining Schedule

Aim of the Schedule

The aim was to generate a practical, realistically achievable schedule which maximises value within the constraints.

A practical, realistically achievable schedule is one that:

� Meets mill feed requirements.

� Includes ramp-up considerations for mine operations as well as the processing plant.

� Avoids vertical advance rates of >100 m per annum.

� Is centred around a stable fleet size that does not vary too much between periods and is sufficient to undertake the work without unnecessary excess capacity.

� Avoids congestion on benches and ramps.

Maximum value is achieved by:

� Bringing forward higher grade, lower cost ore as much as possible.

� Delaying waste mining as much as possible. This includes keeping the pre-stripping period as short as possible.

� Avoiding rehandling and avoiding stockpiles larger than necessary.

In order to obtain sufficient resolution of material movement and hence mill feed during the early years of the operation, and to raise the confidence in the achievability of the schedule, the first 4 years (including the pre-stripping period) of the Life of Mine (LOM) schedule were undertaken in monthly periods with quarterly increments thereafter.

Scheduling Targets and Constraints

The processing plant feed schedule aims to meet the following criteria during each scheduling period:

� Plant feed rate of 3.0 Mtpa when the fresh rock proportion of the feed is greater than 75%.

In addition, it is preferred to have a stockpile size of approximately 2 weeks capacity, i.e. 115,000 t.

Scheduling Process

All mining schedules were generated in EVORELUTION, a sophisticated block-by-block scheduling software. The scheduling is undertaken on all materials within the stages presented in Table 15.7.1. The stages enhance the ability of the scheduling software to target the mining of better parts of the pits and to delay the mining of other, less favourable, parts in order to maximise the Project value.

The scheduling process has adopted a Truck Based (TB) scheduling approach. This is a true 3D, block by block, method where the ore and waste quantities are dictated by the available truck fleet capacity and the haulage requirements during any period. The objective of the scheduler is to keep the fleet as small as possible and avoid fleet size fluctuations.

TB scheduling also minimises the waste haulage distance in any scheduling period. For any waste materials mined, the shortest possible haul route is selected to the nearest Waste Storage Facility (WSF). A Waste Storage Envelope, with geometry based on the design criteria outlined in Section 15.8, is developed for all available WSF locations. As the schedule progresses, the WSFs are constructed block by block, gradually filling the WSF envelope which generates the lowest cost at that point in time. Hence waste haulage distances increase over time as the WSFs are constructed.

A spreadsheet solution was used to apply a direct tip / stockpile reclaim strategy on the final mining schedule and determine the actual processing plant feed.

Scheduling Results

Annualised scheduling results are shown in Figure 16.1.1 to Figure 16.1 5 and Table 16.1.2. The vertical advance rate for each of the stages is summarised in Table 16.1.3.

The key aspects of the schedule are:

� The processing plant is supplied with ore at a rate of 3 Mtpa or higher.

� The feed grade is less than 4 g/t Au at all times.

� The stockpile varies from a high of 0.5 Mt at the end of Year 4 to a low of 40 kt in Years 5 and 6 with an average of 0.23 Mt over the life.

� The duration of the pre-strip period during Year -1 was contained to 3 months and a total quantity of 3.22 Mt.

� The annual vertical advance rates of maximum of 90 m are acceptable.

� During Years 5 and 6 there are only 2 active work areas and all trucks utilise a single ramp. This may introduce inefficiencies which can be avoided by bringing forward one of the other stages.

16.2 Hydrogeology

A groundwater investigation in the Vindaloo Pit area was described in the Groundwater Investigation Report by Knight Piésold (KP ref PE401-00067_02, May 2013, available on request). No primary aquifers were identified in the vicinity of the Vindaloo Pit. Bulk permeability and storativity values were predicted to be low and to be largely controlled by the weathering profile and possible deeper fracturing / faulting.

16.2.1 Groundwater Levels

Groundwater levels along the centre line of Vindaloo Pit (recorded in February 2013 at the end of the dry season) ranged between 2 and 26 metres below ground level (mbgl) with an average value of 14 mbgl. A seasonal variation of less than one metre is expected. The groundwater flow direction is likely to reflect the general topography and flow from the higher elevation ground to the northwest of the pit towards the valley to the southeast.

16.2.2 Permeability Values

Falling head tests were undertaken in 14 monitor bores installed along the centre line of the Vindaloo Pit. Permeability values derived from the falling head tests were very low (2.7 x 10-8 m/s to 1.3 x 10-10 m/s, average 1.8 x 10-9 m/s). Based on the falling head test results the rock mass at depth is likely to have a very low permeability value. A single constant rate pumping test was also undertaken on the existing bore located mid-way along the Vindaloo Pit north wall, which gave a higher permeability value of 1.3 X 10-3 m/s. Higher permeability typically occurs at the base of the weathered zone (possibly the source of permeability in the pumping well) and in association with faults / fractures where present.

October 2013 Orelogy Pty Ltd

16.2.3 Predicted Groundwater Inflows

Groundwater inflow to the pit is expected to be low based on the geology and the predominantly low permeability values encountered. Based on standard analytical flow equations the estimated groundwater inflow to the pit (excluding incident rainfall and surface water runoff) is 6 L/s when the Vindaloo Pit is fully developed. It is anticipated that groundwater seepages may take place at the base of the weathered zone and possibly in association with deeper fracturing / faulting that will be controlled by in-pit sumps. Abstraction from the existing bore located mid-way along the Vindaloo Pit north wall will also assist with pit dewatering as well as provide a water supply for construction and dust suppression purposes. It is noted that the presence of water bearing structures such as faults / fractures or shear zones cannot be ruled out.

16.2.4 Baseline Water Chemistry

Water samples collected from dams, surface water, drill holes and wells in the vicinity of the Houndé project (50 samples) were very fresh (total dissolved solids (TDS) 14 to 451 mg/L, average TDS 114 mg/L), slightly acidic (pH 5 to 7.9, average pH 6.3), and bicarbonate dominated water typical of rainwater or recently recharged groundwater. Chromium (in three samples) and arsenic (one sample) occurs above the 2011 WHO Drinking Water Quality Guideline Values.

16.3 Fleet Size and Personnel Numbers

Fleet productivity was developed on the basis of a Caterpillar 6030 290 tonne excavator matched to a Caterpillar 785D 140 tonne dump truck. The shovel productivity and truck payload were calculated as shown in Table 16.3.1.

Details of mining capital and operating costs are provided in Section 21.1 Mining Cost Estimates.

16.5 Technical Risks and Opportunities

16.5.1 Open Pit Optimisation

1 The open pit optimisation process highlighted the sensitivity of the project value to changes in price / processing recoveries / grade, which are the usual triumvirate of parameters as they all directly affect revenue. The use of a Revenue Factor of 0.88 for the final shell selection, which effectively equates to a base gold price of $1,144/oz represents a relatively conservative approach and provides some mitigation against variations in these modifying factors.

2 As indicated by P O’Bryan & Associates, the slope design parameters for the final pit optimisation analysis were based largely on “what is thought to be reasonable upside for the project”. To mitigate the potential risk to production delays, ongoing geotechnical assessments will need to be undertaken during the life of the operation, particularly on the impact of the shear zones.

16.5.2 Mine Design

1 The impact of further development drilling in and around the main orebody has the potential to impact on both the final pit design and the layout of the surrounding infrastructure (i.e. waste storage facilities, haul roads etc.). Drilling of any prospective mineralisation close by the orebody should be prioritised such that any requirements to modify the site layout can be made before mining is too far advanced.

2 The pit designs include 0.66 Mt of Inferred Mineral Resources at a diluted grade of 1.61 g/t Au (variable cut-off applied). This material is currently reported as waste. This material is distributed through a number of the pits and does not present as one cohesive drilling target. It is recommended that an evaluation is undertaken to determine whether more resource drilling is warranted to increase the geological confidence levels of these Inferred Mineral Resources.

16.5.3 Mine Scheduling

1 Re-optimise the waste development sequence to align with the mine lease boundaries.

2 Conduct sterilisation drilling of the Koho mineralisation on the east side of Vindaloo Main before the 2nd quarter of Year 2; prior to commencing waste dump construction of the Vindaloo Main East WSF.

3 Bring a minimal amount of waste forward in Years 1 to 3 in order to:

a. Reduce the vertical advance rate in Year 7 in the Vindaloo 2 pit.

b. Reduce the TMM to within the capacity of the primary loading fleet over the Year 4 to Year 5 period when the 992 FEL is required to undertake some primary loading of pit waste.

4 Conduct evaluation into the effect of the single lane ramps on traffic congestion.

16.5.4 Cost Estimation

1 More detailed due diligence of competitive mining equipment should be undertaken and more detailed budget estimates obtained before a final OEM is selected. The decision should not be based on cost alone but should include assessment of:

a. In-country track record and support personnel / facilities.

b. Number of units in operation in Burkina Faso, Africa and world-wide.

c. Performance guarantees and availability of spares.

2 The potential to purchase second-hand equipment, particularly for the trucks that are required mid-life, should be investigated.

3 A 51 minute working hour has been selected for cost estimation purposes. This is on the basis that Endeavour will be able to source and train a competent and skilled workforce from start-up. Additional funds were specifically allocated to training to improve mine team safety and efficiencies.

4 As owner / operator, securing a long term supply for fuel and tires is of critical importance.

5 Personnel costs currently constitute an extremely low proportion of the overall mining costs (<9%). Should the mining industry in Burkina Faso expand over the next few years, as is predicted, then the associated competiveness for skilled staff may well increase this cost.

17.0 RECOVERY METHODS

17.1 Process Selection

The process plant design will reflect a robust metallurgical flowsheet designed for optimum recovery with minimum operating costs and utilising unit operations that are well proven in industry. The key criteria for equipment selection are suitability for duty, reliability and ease of maintenance. The plant layout provides ease of access to all equipment for operating and maintenance requirements whilst maintaining a compact footprint that will minimise construction costs.

The key project and ore specific criteria for the plant design are:

� 3,000,000 t/y (9,000 t/d) throughput of the life of mine (LOM) blend ore, 88% Primary and 12% Saprolite / Transition.

� Mechanical availability of 91.3% supported by crushed ore storage and standby equipment in critical areas.

� Sufficient instrumentation and automation to achieve design production rates, to enable stable process operations and to facilitate safe operation.

The Houndé Plant has been designed to treat the range of ore types and blends that will be mined over the life of the project.

17.1.1 Selected Process Flowsheet

The treatment plant design incorporates the following unit process operations:

� Primary crushing with a single toggle jaw crusher to produce a coarse crushed product.

� A live stockpile from which ore will be reclaimed to feed the milling circuit.

� A SABC milling circuit comprising a SAG mill in closed circuit with a pebble crusher and a ball mill in closed circuit with hydrocyclones to produce an 80% passing 90 micron grind size.

� A gravity circuit utilizing continuous centrifugal gravity concentrators to recover free gold and occluded gold in coarse or heavy particles (pyrite) from the milled slurry to a low mass gravity concentrate. The design mass pull of 2.5% to gravity concentrate was nominated based on recovery data and the installed power for the selected fine grinding mill and a typical fine grind specific energy requirement.

� A gravity concentrate regrind and leach circuit comprising an ultra fine grind (UFG) mill in closed circuit with cyclones to produce an 80% passing 10 micron grind size followed by a concentrate leach circuit providing a total of 4 hours leach time.

� Pre-leach thickening of the gravity tails to increase the slurry density feeding the carbon in leach (CIL) circuit to minimise CIL tankage, improve slurry mixing characteristics and reduce overall reagent consumption.

17.2 Process and Plant Description

17.2.1 ROM Pad

The Run of Mine (ROM) pad will be used to provide a buffer between the mine and the plant. The ROM stockpile will allow blending of ore feed stocks, and will ensure a consistent feed type and feed rate to the plant. ROM ore will be loaded into the crushing circuit feed bin (ROM bin) by direct tipping from the mining haul trucks or by front end loader (FEL).

17.2.2 Crushing and Grinding Circuit

ROM ore will be drawn from the ROM bin at a controlled rate by an apron feeder and discharged onto a vibrating grizzly. The grizzly oversize will report to the jaw crusher for primary crushing. The jaw crusher product together with grizzly undersize will report to the primary crusher discharge conveyor feeding directly to the crushed ore stockpile.

Ore will be withdrawn from the coarse ore stockpile and fed via the mill feed conveyor to the SAG mill. Lime and SAG mill grinding media will be added to the mill feed conveyor as required.

The grinding circuit will consist of a SAG mill in open circuit, a pebble crusher and a ball mill in closed circuit with hydrocyclones.

The SAG mill will discharge via a pebble dewatering screen, and oversize consisting of pebbles and worn steel grinding media, will discharge onto the pebble transfer conveyor. Worn media will be removed by a magnet and pebbles will be crushed in the pebble crusher and will report back to the SAG mill conveyor. The screen undersize will gravitate to the mill discharge hopper and will be pumped to the hydrocyclone cluster for size classification.

The cyclone underflow (coarse material) will report to the ball mill feed chute for further grinding. The cyclone overflow (product size material) will gravitate to the trash screens prior to gravity concentration and leaching.

17.2.3 Trash Screening

Cyclone overflow will gravitate to two trash screen located in the CIL area for removal of trash material and coarse particles. The underflow of the trash screens will gravitate to the gravity circuit for gravity concentration.

17.2.4 Gravity Circuit

Milled and screened slurry will report to the gravity circuit where it will be treated by centrifugal gravity concentrators to recover the free coarse gold and gold associated with coarse sulphide and silicate particles. The low mass gravity concentrate (2 to 3% of feed tonnage) will report to the concentrate UFG circuit and the gravity tails will report to pre-leach thickening.

17.2.5 Gravity Concentrate Treatment

The gravity concentrate treatment circuit will consist of a UFG mill in closed circuit with hydrocyclones and a concentrate leach circuit.

The gravity concentrate will gravitate to the concentrate storage tank which will provide a buffer for the UFG circuit. Provision will be made to add peroxide solution to the concentrate storage tank. UFG feed slurry will be pumped to the UFG mill for fine grinding. The ground slurry will be diluted and pumped to the UFG cyclones for classification. The UFG cyclone underflow (material requiring further grinding) will report to the concentrate storage tank for further grinding. The UFG cyclone overflow (reground concentrate size material) will gravitate to the concentrate leach tanks.

The concentrate leach circuit will consist of two leach tanks providing 4 hours residence time. Caustic and peroxide solutions will be added to ensure that the slurry pH (caustic) and dissolved oxygen level (peroxide) is suitable for cyanidation. Sodium cyanide solution will be metered into the leach circuit and air from dedicated blowers will be sparged down the shafts of the leach agitators to provide oxygen to the leach slurry.

Leached concentrate will be pumped to the CIL circuit for gold adsorption as well as using any residual sodium cyanide in the concentrate slurry.

17.2.6 Pre-leach Thickening

Tails from the gravity circuit will be thickened in a high rate thickener prior to CIL. The thickener feed slurry will be mixed with flocculant and will report to the pre-leach thickener.

The thickened slurry (thickener underflow) will be pumped to CIL and the thickener overflow will gravitate to the adjacent mill water tank and will be distributed as dilution water to the milling and UFG circuits. Process water from the process water pond will be added to the mill water tank to balance mill water requirements.

17.2.7 Leach and Adsorption Circuit

The adsorption circuit will consist of six CIL adsorption tanks providing 36 hours residence time (the minimum 24 hours required by the testwork can still be achieved if the thickener is by-passed). The tanks will be interconnected with launders and slurry will flow by gravity through the tank train.

Pre-leach thickener underflow and leached concentrate will be combined as CIL feed. Quicklime added to the mill feed conveyor will ensure that the slurry pH is suitable for cyanidation and sodium cyanide solution will be metered into the CIL circuit. Air from dedicated blowers will be sparged down the shafts of the CIL agitators to provide oxygen to the leach slurry.

Barren activated carbon will be added to the last tank and advanced counter current to the slurry flow. The leached gold will adsorb onto the carbon and be removed from the CIL slurry. Carbon loaded with gold (loaded carbon) will be recovered from the CIL slurry via the loaded carbon recovery screen and will report to the elution circuit.

Slurry from the last CIL tank (CIL tails) will gravitate via the carbon safety screen to the cyanide destruction circuit.

17.2.8 Elution and Gold Recovery

The following operations will be carried out in the elution and goldroom areas:

� Acid washing of loaded carbon.

� Stripping (elution) of gold from loaded carbon using the split AARL method.

� Electrowinning of gold from pregnant solution.

� Smelting of electrowinning products.

� Regeneration of barren carbon.

Loaded carbon will be washed with a dilute acid solution to remove contaminants prior to being rinsed with water. The loaded carbon will be eluted with a hot dilute cyanide / caustic solution which will recover the gold from the carbon into the solution. The gold solution (pregnant solution) will be pumped through electrowinning cells and the gold will be recovered onto the cell cathodes. The gold will be removed from the cathodes by high pressure water jets with the gold sludge being filtered and dried prior to smelting with fluxes in a furnace to produce doré bars.

Eluted carbon (barren carbon) will be transferred to the carbon regeneration kiln for reactivation prior to re-use in the CIL circuit.

17.2.9 Cyanide Destruction

Endeavour Mining Corporation is committed to meeting or exceeding the ICMC requirements. An SO2 / air cyanide destruction circuit will be utilised to meet this requirement. The SO2 / air destruction circuit will reduce the weak acid dissociable cyanide (CNWAD) in the slurry discharged from the CIL circuit to less than 50 mg/L prior to pumping to the TSF.

The cyanide destruction circuit will consist of two tanks providing one hour residence time. The tanks will be interconnected with launders to allow the circuit to be run in parallel or series.

Underflow from the CIL circuit carbon safety screen will gravitate to the cyanide destruction circuit. Copper sulphate and sodium metabisulphite (SMBS) solutions will be added to provide the required copper and sulphur dioxide for the cyanide destruction process. Air from dedicated blowers will be sparged down the shafts of the cyanide destruction agitators to provide oxygen to the slurry. Provision will be made for caustic solution to be added to maintain a slurry pH 8.0 to 9.0.

Treated tailings will gravitate to the tailings tank and will be pumped to the TSF.

Plant and Instrument Air Supply - Plant and instrument air will be supplied from air compressors and will be filtered and dried before distribution with separate plant and instrument air receivers.

17.3 Control Philosophy

The general control philosophy for the plant is to provide a moderate level of automation and remote control facilities. Instrumentation will be provided within the plant to measure and control key process parameters, while still requiring manual inspection of equipment before starting.

The main control room will house two PC based operator interface terminals (OIT). Both of the OITs will act as the control system supervisory control and data acquisition (SCADA) servers as well as configuration / operator stations. The control room is intended to provide a central area from where the plant is operated and monitored and from which the regulatory control loops can be monitored and adjusted. All key process and maintenance parameters will be available for trending and alarming on the process control system (PCS).

The process control system that will be used for the plant will be a programmable logic controller (PLC) based SCADA system. The PCS will control the process interlocks and PID control loops for non-packaged equipment. Control loop set-point changes for non-packaged equipment will be made at the OIT.

In general, the plant process drives will report their ready, run and start pushbutton status to the PCS and will be displayed on the OIT. Local control stations will be located in the field in proximity to the relevant drives. These will, as a minimum, contain start and latch-off-stop (LOS) push-buttons which will be hard-wired to the drive starter. Plant drives will predominantly be started by an operator in the field after inspecting the local equipment.

The OITs will allow drives to be selected to Local or Remote or Maintenance modes via the drive control popup. Statutory interlocks such as emergency stops and thermal protection will be hardwired and will apply in all three modes of operation. All PLC generated process interlocks will apply in Local and Remote modes. Process interlocks will be disabled or bypassed in Maintenance mode with the exception of critical interlocks such as lubrication systems on the mill.

Local selection will allow each drive to be operated by the operator in the field via the local start pushbutton which is connected to a PLC input. Remote selection will allow the equipment to be started from the control room via the drive control popup. Maintenance selection will allow each drive to be operated by maintenance personnel in the field via the local start push-button which is connected to a PLC input. A PLC output will be wired to each drive starter circuit for starting and stopping drives. Status indication of process interlocks as well as the selected mode of operation will be displayed on the OIT.

Vendor supplied packages will use vendor standard control systems throughout the project. Vendor packages will generally be operated locally with limited control or set-point changes from the PCS system. General equipment fault alarms from each vendor package will be monitored by the PCS system and displayed on the OIT. Fault diagnostics and troubleshooting of vendor packages will be performed locally.

18.2 Roads

18.2.1 Road Types

A range of road types will be required to and within the Project site to meet a wide range of duties. The hierarchy of road types includes dedicated mine haul roads, main access roads, general access roads and minor use roads and tracks. Some of the roads will border service corridors, e.g. raw water supply pipe lines, or tailing pump line access. Hence, road alignments also need to consider service routes in addition to transport requirements.

The road widths and construction details have been selected to match the required duties. The respective details are described below. The total lengths of the main road types are:

� Mine haul roads Approximately 8.5 km.

� Main access roads Approximately 3.0 km.

� Plant roads Approximately 2.7 km.

� Access tracks Approximately 19 km.

Roads will generally follow existing tracks or contours where no direct route can be achieved with the aim to minimise disruption to local villages and crop fields.

Interpretation of the geotechnical test results and ground conditions suggests that the local soils are typically clayey / gravely silt with low plasticity and less than ideal for road pavement construction.

Laterite gravel material, to form the base course for minor roads and the sub-base for heavy use roads, will be sourced from borrow pits along the main roads within the purchased property area or within the open pit mine footprint. Suitable gravel borrow areas will be identified during the next phase of the Project.

18.2.2 Access to Site

Current road access to the plant site from the N1 Highway is on an unsealed track for 1.5 km – this will be upgraded, to a sealed, 9 m wide road. The proposed camp will be approximately 1 km from the main access road and will be a 7 m wide unsealed road.

18.2.3 Project Site Roads

Mine Haul Roads

Mine haul roads will be designed and constructed by the mining department to access the pits, waste dumps and ROM pad. The mining services facilities will be designed and built by the EPCM contractor.

HOUNDÉ GOLD PROJECT, BURKINA FASO FEASIBILITY STUDY NI 43-101 TECHNICAL REPORT

1813.20\25.01\1813.20-STY-001_B S18

Page 18.4

October 2013 Lycopodium Minerals Pty Ltd

Main Access Road

The 1.5 km section of access track will be reconstructed, widened, and sealed to form the main access road. The road will have a width of 9 m with two 3.5 m wide sealed lanes and 1 m shoulders. The road will follow the natural grade of the ground and designated crossing points for farm machinery, herding or walking will be provided near where current, well used trails exist.

The proposed road alignment passes under the 225 kV power line near to a cable tower in order to provide a clearance envelope of 10 to 12 m under the minimum 5.5 m clearance to the lowest power cable. A berm of waste rock will be placed to protect the tower base.

The intersection of the main access road with the N1 Highway, has been designed for a speed limit of 60 km/h, and will include a centre island with dedicated turning lanes for vehicles entering the main access road. Street lighting will be installed at the junction approaches to improve visibility and safety during night time.

Camp Access Road

The camp access road will be 7 m wide and will be constructed as an unsealed all-weather road with appropriate drainage provisions where necessary.

Plant Roads

Plant site internal roads will be 7 m wide and will be constructed flush with the bulk earthworks pad to ensure that storm water sheet flow is achieved across the site, avoiding the need for deep surface drains and culvert crossings within this area.

Access Tracks

A number of tracks will be constructed to access infrastructure such as the water storage facility, bore pumps and tailings dam which are remote from the plant site. These access tracks will generally follow the alignment of existing tracks and will be cleared and graded natural earth tracks. Pipeline routes will generally follow the access tracks.

18.3 Rail Connections

The main railway line between Abidjan, the chief port in Cote d’Ivoire, and Ouagadougou passes approximately 28 km to the north of the project site along the D40 main road heading north west from Houndé town. The station at Béréba services the local cotton producers, and with minor modifications would be suitable as a terminal to receive construction materials and equipment and ongoing operational supplies, especially those that can be containerized for security of shipment and ease of handling.

18.4 Port Facilities

The main ports serving project are Abidjan, in Cote d’Ivoire and Tema in Ghana. Both ports are connected to Burkina Faso by main roads and provide the prime entry point for importation of equipment and fabrications. Both ports are able to handle all types of cargo required for the project.

18.5 Water Supply

18.5.1 Water Demand

A water balance model was prepared to estimate the demand for raw water on site, considering the process water demand, losses and gains from the tailings storage facility, pit dewatering and dust suppression and runoff from the ROM pad and plant site. Utilization of ground water resources from boreholes was incorporated into the model. Any potential shortfall was modeled to be supplied from a water storage dam which will be fed from a water harvesting dam.

The total water demand for the site was estimated at 3.3 Mm3 per year. The water demand for the process plant amounts to 2.85 Mm3, which includes the minimum raw water requirement of 0.49 Mm3 but excludes water in ore. Other water demands include a provision of 0.54 Mm3 for dust suppression. The demand will be met from TSF decant, pit dewatering (including precipitation on the pit area), runoff from the ROM pad and sub-ore stockpiles.

Potable water demand for the project has been estimated from the number of persons expected to be working and living on site, and the per capita daily demand estimated from similar projects in the region.

18.5.2 Decant From Tailings Storage Facility

The water balance modelling indicated that for tailings pumped to the TSF at 50% solids, the pond on the TSF would increase during the wet season and reduce to the minimum pre-set level during the following dry season. Recovery from the TSF decant would gradually increase to supply up to 79% of the process water demand, or up to 2.3 Mm3 per year, in the later years of operation. The water balance modelling is described in the Site Water Management Report prepared by Knight Piésold (Report PE401-00067_05, July 2013, available on request).

18.5.3 Groundwater Investigation

Knight Piésold carried out an investigation into groundwater sources in the project area with the aims of estimating the likely volumes of water arising from open pit mine dewatering and the availability of water to meet the project demand. Details of the investigation are available on request in Knight Piésold’s Groundwater Investigation Report PE401-00067_02 Rev B, May 2013. The report concludes that the contribution from pit dewatering, including external groundwater sources of 8 L/s and precipitation on the pit surface is estimated to be up to 1.5 Mm3 per year, depending on the extent of the pit development.

18.5.4 Surface Water

The water balance model assumes that any water demand which could not be met from the tailings storage facility, pit dewatering or groundwater sources, will be met from surface water sources. The models were run on a monthly basis for the life of mine for average climatic conditions and tested for a 1 in 100 year dry event and 1 in 100 year wet event occurring when each would have the greatest impact on operations. Under average climatic conditions, the water demand from surface water sources decreases as the tailings beach in the tailings storage facility increases, resulting in higher recovery of precipitation on the tailings storage facility. The recovery from pit dewatering also increases as the pit surface increases.

The demand from surface water sources is highest in the year when the process plant is commissioned, when under average climatic conditions 1.75 Mm3 is required from the water storage dam. The demand for surface water decreases to 1.2 Mm3 in the 9th year of operation.

Water Harvest Dam

A water harvest dam will be constructed east of the pit. The mean annual runoff at the dam site is estimated to be 4.8 Mm3 from a catchment area of 21,850 Ha. The required earth fill embankment will be 8 m high and 760 m long to create a storage capacity of 1.8 Mm3. The surface area of the dam at full supply will be 120 Ha. A spillway will be provided to safely pass a 1 in 100 year peak flood. The embankment will be constructed from material excavated from the basin. The embankment will consist of several zones, including a low permeability core, a chimney drain, a structural layer and, on the upstream face, a layer of non-dispersive material covered by an erosion protection layer. The embankment slopes will be 2.5H:1V on both upstream and downstream faces.

Due to the flat topography at the dam site, the proposed water harvesting facility on its own would not meet the project water demand on a sustainable basis; therefore a supplementary water storage dam was identified.

Water Storage Dam

A more favourable storage site was identified approximately 5 km west of the water harvest dam site. This storage dam would have a catchment area of only 400 Ha and so could not replace the harvest dam, but due to its more efficient storage characteristics and relatively small embankment, it was selected as a storage facility to be supplied from the harvest dam during the wet season. The water storage dam will have a capacity of 1.5 Mm3 and will have a surface area of 58 Ha at full capacity. The required earth fill embankment will be 10 m high and 130 m long. The embankment construction will be similar to that described for the water harvest dam.

Water will be pumped from a decant structure in the water harvest dam to the water storage dam at a rate of 600 m3/h to build up storage capacity for use during the dry season, when the water harvest dam could be empty. The demand from the water harvest dam is highest in the first year of operation, when the process plant will have to be supplied and storage built up in the storage dam. The peak annual demand for surface water was projected to be 2.4 Mm3 (Note: The mean annual runoff at the harvest dam site is >4.8 Mm3. Therefore, if water is pumped at a high enough rate, water could be harvested and pumped to the storage facility during the rainy season when the dam will mostly be at full capacity or spilling).

18.6 Tailings Storage Facility (TSF)

18.6.1 Capacity and Location

A tailings storage facility (TSF) with a capacity of approximately 25 Mt will be required to store the tailings generated by the process plant over a period of about 8 to 9 years, at a rate of 3 Mtpa. The TSF was designed to international standards to provide a facility to safely contain the tailings and reduce the potential effect thereof on the environment in the form of dusting, seepage or runoff from the tailings surface during operation and post closure. The design complies with the guidelines proposed by the International Committee on Large Dams (ICOLD) and Guidelines on Tailings Dams: Planning, Design, Construction, Operation and Closure (ANCOLD 2012). Provision was made for the effects of seismic events and probable maximum precipitation events during operation and post closure. To support the design and improve the safety of the facility, a dam break analysis, seepage analysis and stability analysis were performed on the embankments. A water balance model was prepared to determine the impact of extreme rainfall events on the TSF pond. If built and operated in accordance with the principles and design concepts outlined in this document, this facility would contain the tailings generated from the project and the effects on the environment would be within acceptable limits as defined by international standards.

Seven locations were evaluated as potential sites for the TSF. The selected site, a valley storage facility approximately 5 km to the west of the proposed process plant site will require a main embankment 668 m long and 23 m high and three smaller saddle embankments respectively 130 m long and 10 m high, 755 m long and 15.5 m high, 1,116 m long and 7 m high. It is estimated that the tailings surface at full capacity will cover approximately 200 ha. It is noted that the selected site has the potential to provide storage in excess of the required 25 Mt of tailings by increasing the embankment height and, if required, adding a saddle embankment to the south of the facility. Initial estimates indicate that by increasing the embankment height by 9 m, the storage capacity of the TSF could potentially double.

18.6.2 Design Considerations

Tailings will be pumped to the TSF as a slurry at 48% to 50% solids and will be deposited sub-aerially to facilitate drying and consolidation of the tailings mass. It is expected that in the TSF a density of approximately 1.4 t/m3 will be achieved initially, increasing to 1.6 t/m3 to give an overall final density of 1.55 t/m3.

The tailings acid base accounting indicated that the tailings would be acid consuming. The assay results showed that the tailings solids had a low number of elemental enrichments, with arsenic, selenium and antimony significantly enriched and chromium slightly enriched. Note that elemental enrichment is expected in any mineralogical deposit. A comparison with soil intervention guidelines indicated that the element concentrations for chromium, manganese, nickel, sulfur, sulfate and vanadium significantly exceed the soil intervention guidelines. The sample also marginally exceeded the guidelines for arsenic and copper. The results of this comparison indicate that a cover system designed to isolate the tailings facility from the environment will be required on closure to prevent migration of tailings. The cost of an appropriate cover system has been included in the design and closure costs.

The tailings supernatant was tested against reference water quality standards for release of water from mining operations and livestock drinking water. Endeavour intends to install a cyanide destruction unit as part of the process, which will reduce the WAD cyanide to below 50 ppm at the spigot discharge into the dam, as recommended by the ICMC. Arsenic and antimony were present at levels which would require dilution before releasing into aquatic systems as surface flows. It will therefore be required to store a minimum of a 1 in 100 year wet event on the TSF without release to the environment (this minimum only occurs in the dry season when the tailings are at the maximum level prior to the next embankment lift being constructed). It is estimated that the concentration of substances in the tailings water will be diluted more than 50 times for a 1 in 100 year event. When compared with background groundwater quality, the tailings supernatant contained arsenic at levels higher than the groundwater and the release standards. A suitable seepage reduction system will therefore be installed for the TSF to reduce the risk of tailings supernatant affecting the groundwater.

18.6.3 Geotechnical

A geotechnical investigation on the tailings site indicated that the laterite was on average 1 m thick, followed by more than 5 m of saprolite, overlying the saprock or transition material. Seepage analysis undertaken for the TSF site indicated that the saprolite provided a low permeability layer with an effective permeability which varied between 2.0 x 10-10 m/s for Stage 1 to 4.6 x 10-11 m/s for the final stage. The unit seepage rate was calculated at 0.17 kL/ha/day for Stage 1 and 0.07 kL/ha/day for the final stage. These rates are lower than the Australian guideline value of <1 kL/ha/day, which is currently the most stringent guideline (a seepage rate of 1 kL/ha/day is equivalent to a base permeability of 1 x 10-9 m/s with 1 m of water head). The seepage analysis further indicated that due to the low effective permeability of the layer of saprolite below the facility there would be minimal benefit to installing drains other than toe-drains at the embankments.

A seismic analysis was done for the site, which indicated that the maximum credible earthquake would be a M5.8 shallow crustal earthquake occurring within 53 km of the site, causing peak ground acceleration (PGA) of 0.10 g. Comparison with the probabilistic analysis results indicates this acceleration to be similar to the PGA calculated for the 1 in 20,000 year return interval. The site is considered to have a low seismic hazard rating.

A dam break analysis was carried out on the TSF embankments, (see Figure 18.5.1) which resulted in the classification of the facility as a “High” consequence rating. Embankment 2, which has the largest potential impact in the event of a failure, will be built using the downstream construction method to mitigate the ‘high’ consequence rating, while Embankment 1 and Embankment 3 will be built downstream for Stage 1 and centreline for subsequent stages. The earthfill embankments will be constructed with engineered zones, comprising a low permeability upstream face with a cut-off trench extending through the laterite into the underlying saprolite, followed by a downstream structural zone. For embankments of downstream geometry the upstream slopes will be 2H:1V, an operating downstream slope of 3H:1V and a crest width of 6 m. The final downstream embankment profile will consist of 3H:1V slopes with 5 m wide benches at 10 m height intervals, producing an overall slope of 3.5H:1V for ease of rehabilitation.

18.6.4 Operation

Tailings will be deposited off the embankments and the north-western ridge to form a decant pond away from the embankments, against the ridge forming the western limit of the TSF.

The tailings settling performance will be monitored regularly from density and flow measurements, and piezometers will be installed to measure the phreatic surface in the embankment to ensure the stability is not compromised. Survey pins will be installed to detect potential movement of the embankment. Six boreholes will be installed downstream of the embankments to monitor seepage from the facility (see Figure 18.5.2).

The TSF site has a catchment area of 320 ha, which includes the tailings surface of 200 ha at full capacity. Emergency spillways will be constructed for each construction stage to provide for events exceeding the designed storage capacity. (If such a release occurs, the concentration of metals in the supernatant liquor will be diluted to such an extent as to be safe for release – see Section 18.5.2 above). The spillway for the final stage will also be used as the post-closure spillway for the facility and will be designed to safely discharge the Probable Maximum Flood.

At closure, the embankments will be rehabilitated and revegetated and the TSF surface will be covered with a layer of waste rock to prevent root growth into the tailings and finished with a soil layer, shaped to be free draining towards the closure spillway.

18.7 Surface Water Management

18.7.1 Design Objectives

The surface water management at the site will incorporate control measures in order to reduce impacts to downstream environments for all aspects of the Project, from initial development through to completion of rehabilitation.

The main objectives of the management of surface water on the site are summarised as follows:

� Maximising the internal recycle of contact and process waters in ore processing and thereby minimising the use of external water sources.

� Minimise the impact of the proposed mining activities on the quality and quantity of surface water. This is achieved by routing clean surface water runoff around disturbed areas and minimising sediment discharge from the site to the environment by entrapping and retaining eroded sediment as close as possible to disturbed areas.

� Protect internal infrastructure and personnel from the uncontrolled effects of surface water runoff during storm events, thereby enhancing the safety of project personnel and reducing maintenance costs.

� Provide long-term post-mining erosion and sediment control measures, including where practical the establishment of fully stabilised and protected final reclaimed surfaces that require minimal maintenance.

The following four categories of water were identified on the site:

� Undisturbed water (U) Runoff from undisturbed catchments.

� Contact clean water (CC) Runoff from disturbed catchment areas with some sediment pickup.

� Contact dirty water (CD) Runoff from disturbed catchment areas with potential for contamination; sources include runoff from sub-ore stockpiles, ROM pad and plant site.

� Process water (P) Water that has passed through the process or come into contact with process water.

Based on the above classifications, the following main components are required:

18.7.2 Diversion Structures

It will be necessary to alter the current flow path of surface water flows to reduce the potential for harm to people or infrastructure or to minimise the potential for mixing clean water with runoff from disturbed sites. The following structures are envisaged.

HOUNDÉ GOLD PROJECT, BURKINA FASO FEASIBILITY STUDY NI 43-101 TECHNICAL REPORT

1813.20\25.01\1813.20-STY-001_B S18

Page 18.13

October 2013 Lycopodium Minerals Pty Ltd

Stream Diversions

The Vindaloo North pit will extend across one of the drainage channels feeding the water harvest dam. A stream diversion will be installed to divert the flow of Undisturbed water around the northern tip of the pit to reduce the risk of flooding of the pit when runoff occurs. The diversion has been designed to safely pass a 1 in 100 year storm event.

Diversion Berms / Channels

A series of diversion berms and/or channels will need to be constructed over the life of the mine, as development progresses, to separate Undisturbed water from other water categories at the plant site, ROM pad, sub-ore stockpiles, pit and waste rock dumps.

18.7.3 Collection and Control Structures

Runoff from areas designated as Contact Clean (CC) water and Contact Dirty (CD) water will be directed to Sediment Control Structures and Collection Structures, respectively. The sediment control structures will provide adequate retention to allow settling of medium sized silt, but will have spillways to pass flows larger than 1 in 10 year recurrence interval.

Collection Structures

Runoff from the ROM pad and sub-ore stockpiles will be directed to a Collection Structure downstream of the stockpiles. The quality of the water collected from these areas will be tested and the water either released to the environment after providing time for solids to settle, or pumped to the process plant as process water.

Sediment Control Structures

Runoff from CC disturbed areas such as the waste rock dumps will be collected and directed to one of eight proposed Sediment Control Structures to provide retention time for sediment to settle, before water is released to the environment.

It is noted that the water harvest dam is situated downstream of the site in such a position that it will capture sediment not settled in other structures upstream thereof. The dimensions of the water harvest dam are such that it would provide adequate retention time for medium sized silt (>20 μm) to settle.

The position of the surface water management structures at Houndé in relation to the mining areas is described in the Site Water Management Report prepared by Knight Piésold (Report PE401-00067_05, July 2013), available on request.

18.8 Power Supply

The National Electricity Company of Burkina Faso (SONABEL) has confirmed that the Houndé Gold Project demand can be met by the existing power generation and transmission network and SONABEL has agreed in principle to sell the project power. However, negotiation of the means and final cost details has not been completed yet.

HOUNDÉ GOLD PROJECT, BURKINA FASO FEASIBILITY STUDY NI 43-101 TECHNICAL REPORT

The preferred option for the high voltage supply for the Houndé Project will be a tap off from the existing 225 kV line interconnecting between the Kodeni and Pa substations. Two tension towers will be erected at close proximity to the 225 kV line tap off point, allowing 225 kV supply to be fed to the Houndé switchyard. This switchyard will be located about 70 m from the process plant HV switchroom. Refer to the high voltage supply option drawing 330-E-301. (Note that while the preferred option of the above 225 kV connection has been used as the basis for the study, negotiations are continuing with SONABEL to confirm this power supply arrangement, rather than installing a 90 kV feeder line from the Pa substation back to the Houndé project. Should the lower voltage supply from Pa be stipulated by SONABEL, then a Static VAR Compensation facility will be required to ensure that the mill motors can be started without adversely affecting system voltages.) The grid network stability analysis revealed the 225 kV supply will provide more stable operation for the mill drives, with only infrequent to rare power outages likely to be experienced.

18.9 Power Distribution

The main distribution voltages are 11 kV and 415 V for the process plant. Refer to the power distribution overall plant single line drawings 330-E-302 and 330-E-303.

The 225 kV supply will be stepped down to 11 kV via a single 225 / 11 kV, 25 / 35 MVA, ONAF main transformer, feeding the plant 11 kV main switchboard. A standby transformer will be installed in the switchyard and put on ‘soak’ via the 11 kV supply. In case of a failure of the duty unit, the standby unit will be relocated to the duty position to replace the defective unit during a relatively short outage for the transformer replacement work to be carried out. The 11 kV supply will be distributed to various process plant load centres, support facilities, remote facilities and accommodation camp.

A 415 V, 2.5 MVA diesel emergency generator supply with a step-up transformer has been allowed for the essential loads of the process plant during grid power outages. The change over from the grid to the emergency power supply will be effected manually.

The process plant load includes a SAG mill of 6 MW, a ball mill of 6 MW and an 800 kW UFG mill. These mills will be fed at 11 kV. The mill drives include:

� WRIM (Wound Rotor Induction Motors).

� LRS (Liquid Resistor Starters) for starting.

� Heat exchanger for speed control, in the range of 65% - 75% mill critical speed for the SAG mill only.

The 415 V supply to the plant MCCs, plant buildings and remote MCCs will be fed from the plant 11 kV main switchboard via separate 11 kV / 433 V distribution or “transformer kiosks” (HV / LV outdoor prefabricated substations).

Page 18.15

October 2013 Lycopodium Minerals Pty Ltd

The supply to the remote electrical loads such as the water harvest barrage, water storage barrage, accommodation camp site, boreholes and tailings dam will be taken from the mining services kiosk transformer via 11 kV overhead power lines constructed using steel or concrete poles, steel cross arms and earth shield wire, acceptable to the Local Power Authority’s requirements / standards. No overhead power lines will be installed within the plant perimeter area, and insulated cables will be installed on above ground cable ladders.

18.9.1 Total Installed Load and Maximum Demand

The estimated maximum power demand of the process plant is approximately 18.3 MW with a total connected load of 26.5 MW. Refer to the Electrical Load List (1813.20-LST-002) for details.

18.9.2 Electrical Substation Buildings

The three plant electrical substation buildings will be prefabricated flat pack type construction on concrete columns for bottom entry cables. The buildings will be insulated, furnished with air-conditioners, fire detection and alarm systems, lighting and small power.

The remote MCCs / control panels at the water storage barrage, water harvest barrage, boreholes and tailings dam will be installed in outdoor substations with roof covers.

18.9.3 11 kV Switchboard

The plant main switchboard will be metal-clad type with fully withdrawable circuit breakers complete with protection, metering and earthing facilities. Protection will be provided by microprocessor based protection relays.

18.9.4 Power Factor Correction Capacitor

One unit of 11 kV power factor correction capacitor bank will be installed at the plant 11 kV main switchboard to correct the power factor to 0.9 or better as required by the power supply authority.

18.9.5 Internet Fibre Optic Line

The Project will connect to the internet via a fibre optic line from a local carrier. The same fibre optic cable will be used for telephone connections, using Voice Over Internet Protocol (VOIP) for fixed telephone connections. Mobile telephone services are also available in the area.

18.10 Pipelines

18.10.1 Tailings and Decant Return Pipelines

The tailings pipeline will be above ground and follow the alignment of the access road to the TSF in a bunded zone towards the tailings storage facility to the north. This will act as a barrier to movement of stormwater so there will be a need for culvert crossings under the pipeline and road.

The pipelines will pass under the N1 Highway through dedicated culverts.

October 2013 Lycopodium Minerals Pty Ltd

18.10.2 Water Supply Pipelines

The HDPE pipelines from the water dams to the process plant will be laid on surface, running alongside the access track. Where necessary, crossings will be provided for pedestrian, light vehicle traffic and livestock.

18.11 Fuel Supply

The largest user by far of diesel fuel will be the mining fleet, which will consume approximately 1.5 ML/ month in the early years, rising to 1.8 ML/ month later in the mine life. A contract will be entered into with a local fuel supply company for them to supply diesel fuel on a consignment basis and establish their own, 1 million litre storage tank on site.

18.12 General Site Development

18.12.1 Site Topography and Ground Conditions

Geotechnical investigations to determine ground conditions and material properties for the various components of the proposed infrastructure were carried out by Knight Piésold. The investigation results and geotechnical design parameters for use in design and construction of the foundations and earthworks are provided in the Knight Piésold Site Infrastructure Report PE13-00463 available on request. The report concluded that at the tailings dam site, the ground conditions encountered typically comprised a shallow depth of laterite (gravel or silt) overlying saprolite (silt). The materials are initially considered suitable for the construction of embankments if the design incorporates measures to mitigate against the dispersive nature of the soils. Sand for drainage layers will need to be trucked in from local quarries or screened.

The report also considered that the strength and stiffness characteristics of the ground are sufficient for the majority of the plant site’s structures to be founded on shallow spread foundations.

The topography at the Project site is generally open and undulating with the main process plant and mine services facilities located on ground with a gradual natural slope towards the south. The plant will be inset into a cut surface with a 3 metre high western wall; this will help to reduce ground level noise from the plant to the community located 1 km west of the plant area.

There are no major watercourses in the vicinity of the proposed plant site area and the surface water drains naturally toward the valley south east of the site.

18.13 Sewage and Solid Waste Management

18.13.1 Sewage Treatment

Sewage from the accommodation camp, process plant and mining services areas will be collected and treated in two package sewage treatment plants. Sludge will be suitable for direct landfill burial in unlined pits. Treated effluent from the accommodation camp will be discharged to a leach field or a surface spray field at a location to be agreed, while the treated effluent from the plant site and mining services area will be discharged into the tails hopper.

October 2013 Lycopodium Minerals Pty Ltd

18.13.2 Solid Wastes

General solid wastes will be deposited into a landfill, in accordance with local regulations, but dangerous materials such as cyanide packaging, will be incinerated on site to prevent unauthorised use. Other materials unsuited to landfill will be stored on site for later disposal.

18.14 Explosive Storage and Handling

A contract will be entered into with a recognised supplier of mining explosives, to establish his own facilities in the southern end of the eastern waste dump, well away from the local population and mine activities, and to supply emulsion as needed.

18.15 Accommodation Camp

It is anticipated that a significant proportion of the workforce will be recruited from and continue to reside in Houndé town; however, permanent accommodation to house 130 senior operations and mining workforce personnel will be provided approximately one kilometre to the north of the process plant for expatriates and personnel from outside the local district. The camp will be accessed from a new road that links to the mine access road.

The village will have a mix of building types with blockwork construction on concrete slabs and steel trussed roofs for the larger rooms reserved for management, whilst converted sea containers will be used for the junior staff rooms. All buildings will be single storey.

For fit-out and finishes within buildings, preference will be given to locally available equipment and materials subject to availability and quality constraints.

18.16 Process Plant Facilities

18.16.1 General

The process plant support facilities will generally be industrial type structures constructed of a concrete slab on ground with structural steel frame and metal cladding. Office and amenity areas associated with the main structures will generally be of blockwork construction.

The process plant and its support facilities are shown in Figure 18.16.1.

19.0 MARKET STUDIES AND CONTRACTS

19.1 Market Studies

No project-specific marketing studies were undertaken for the Feasibility Study. The planned CIL processing will produce gold doré bullion that is a fungible commodity for which an efficient global market exists. It is of high value density meaning that the realised price of the contained gold is insensitive to the ultimate location of the customer and refinery as freight costs are negligible in comparison to contained value.

Refinery terms of 99.5% payable gold in doré bullion and a refining charge of $3.35 per ounce that were used are typical of current terms being offered for CIL produced gold doré bullion.

19.2 Pricing

Based on review, the long term gold pricing forecast used for the design of the mining project at $1,300 per ounce is consistent with gold prices being used in similar publicly released studies. A common standard is to use the three year-trailing average of the gold price, which in this case is approximately $1,450 per ounce.

The pricing for sensitivity options and economic evaluation utilized $1,000, $1,200 and $1,400 per ounce to be consistent with recent market fluctuations (Figure 19.2.1). In addition, the mining pit optimisation process considered the case for $1,600 per ounce.

19.3 Contracts

No contracts for the sale of the production have been entered into.

20.0 REQUIRED PERMITS AND ENVIRONMENTAL CONSIDERATIONS

Concurrent with this feasibility report, two ESIA studies and a RAP (Resettlement Action Plan) study were carried out by Genivar Inc., INGRID and SOCREGE. This section of the report summarizes the key elements of these studies and cost details. Copies of these supporting reports will be available on request.

Endeavour’s goal is to adhere to both Burkina Faso and IFC standards for the Social and Environmental activities and reporting associated with the Houndé Project.

20.1 Environmental Studies and Permitting

Baseline studies were carried out over a period of nine months to prepare an inventory of data on the physical, biological and socio-economic environments prior to the development of the project. Where seasonal variation was expected, multiple sampling of the environmental feature was undertaken.

The biological environment lacked flora and fauna diversity as a consequence of existing activities including agriculture, grazing of livestock and artisanal gold mining in the area.

The human environment was dominated by traditional community structures and a low level of development based on a cash crop and subsistence economy. The presence of a highway (RN1) adjacent to the site resulted in a number of houses being located in close proximity to the mine site. A trunk line for electricity distribution is also located parallel to the highway alignment.

Studies were also completed to establish the effects of noise and vibration arising from the project on the local communities as well as the quality of the air in the locality of the site. These suggested that the ambient air quality contained high background levels of dust and the noise environment, particularly in areas close to RN1, was quite noisy with noise levels close to existing IFC limits in a number of locations.

Water sampling was carried out on a number of local streams, wells and boreholes to identify the overall quality of water. On average the water quality is slightly acidic and pH of water at individual sites may be lower than the low limit in the WHO standards. Many of the surface water and well sites exceeded turbidity limits and a few sites had iron, chromium and manganese levels in excess of the WHO standard.

To date, there have been no environmental issues that would materially impact the ability of Avion Gold being able to extract the mineral reserves in the area, once the environmental permit has been granted.

The key environmental issues identified include:

� Water supply for the mine;

� TSF location and post-closure land use;

� Transport and management of hazardous materials;

� Proximity of infrastructure (road, power line and optic fibre cable);

� Potential for in-migration and its effect on level of service in public infrastructure;

� Allowance for traditional grazing patterns; and

� Resettlement and reallocation of land.

The key environmental permit required by the project is the environmental certificates from the Ministry of Environment and Sustainable Development (MEED) which will follow submission of the EIA and RAP.

Following receipt of the environmental certificate it is expected that a number of secondary approvals may need to be sought in relation to specific elements of the project:

� Dam licences for the operation of the water dams as described in Decree No. 2005-193/PRES/PM/MAHRH/MFB of 4 April 2005 and the tailings storage facility;

� Licences to store hazardous materials as described in Decree No. 98-322/PRES/PM/MEE/MCIA/MEM/MS/MATS/METSS/MEF of 28 July 1998 including:

- Fuel

- Explosives

- Cyanide and

- Lime.

� Licences for importation of cyanide and ammonium nitrate;

� Licence or approval to remove materials from stream beds as described in Decree No. 2006-588 / PRES / PM / MAHRH / MECV / MPAD / MFB / MS of 6 December 2006;

� Approval of land use and water management plans as described in Decree No. 2005-192/PRES/PM/MAHRH/MFB of 4 April 2005;

� Approval for widening of the RN1 and development of the rural roads from the Ministry of Infrastructure Road Development and Transport;

� Approval to operate the mine under the Mining Code and Decree No. 2007-853/PRES/PM/MCE/MECV/MATD of 26 December 2007; and

� Approval to discharge any effluent as described in Decree No. 2001-185/PRES/PM/MEE of 7 May 2001.

The schedule in Figure 20.1.1 for permitting is the current estimate to enable all approvals to be obtained.

20.2 Anticipated Environmental Costs – Operations

The anticipated operational costs would normally comprise four components:

� Costs associated with maintaining compliance of the operation with environmental legislation, regulations and licenses;

� Costs associated with monitoring according to international codes;

� This costs associated with management of incidental factors; and

� Costs associated with community and social development and accommodation of loss of amenity to the community.

Costs associated with re-vegetation and site rehabilitation are not included as, given the short mine life, it is proposed that these are included in closure costs.

The costs are developed on the following basis:

� The site will retain three full-time environmental and social professionals and one environmental technician, including an expatriate lead;

� Those personnel will be responsible for undertaking all monitoring associated with implementation of the ESMP during the operational life of the mine;

� All sample testing would be undertaken off-site;

� Field monitoring equipment would be acquired as part of the capital expenditure for the project;

� Any works associated with mitigation of amenity loss to the community would be undertaken by local community members as part of a community development project; and

� Costs associated with community development would not exceed 2% of the net profit of the mine.

The overall costs associated with environmental management during the operational phase are estimated to be US$485,000/year, dependent on yearly operational budgets, based on the following:

� Staffing costs of $175,000.

� Water quality testing = $43,000 based on quarterly monitoring of surface water.

� Noise / vibration / air quality monitoring = $13,500 based on one site visit for monitoring.

� TSF monitoring = $13,500 based on monthly surface water sampling.

October 2013 Knight Piésold Pty Ltd

� Biological monitoring = $36,000 per year for 2 seasonal surveys.

� Social monitoring = $54,000 based on one annual survey to monitor social change and impact of community development expenditure.

� Community development = $150,000 for community donations with money spent where a local committee of consisting of an Endeavour representative, community leaders and regional government representatives decide.

Of these costs, the Community Development and Staffing costs (total $325,000) have been included in the General and Administration charges as described in Section 21, while the remaining monitoring costs (total $160,000) have been allowed in the cash flow model in Section 22.

Trialling and monitoring of closure and rehabilitation methods to ensure the efficacy of the methods prior to implementation of closure works, will be carried on over the life of the mine.

20.3 Social and Community Impact

The information and stakeholder consultation process was an integral part of the EIA process. In this regard, since the start of the study, Avion Gold has put in place a mechanism for gathering information and consulting the communities, throughout this process. The information gathered was used to better identify and target issues, to minimize the negative impacts and enhance the positive. A Stakeholder Engagement Plan (PEPP) and various information tools have also been developed for this purpose. A list of stakeholders was also developed and updated throughout the information and consultation process. Information about the project was disseminated through radio and a bilingual information leaflet (French and Dioula) has been given to administrative, technical services and representatives of the affected villages.

As part of this information and consultation process, numerous meetings were held with stakeholders. The main concerns raised during the information and consultation activities were as follows:

� Youth employment at the mine;

� The process of resettlement of affected populations so that they regain their previous standard of living;

� Security issues related to mining operations;

� The water supply of the mine (and its potential impact on watersheds and water supply to nearby villages);

� The rehabilitation of the site following the eventual closure of the mine;

� The Project's impacts on infrastructure and administrative buildings;

� Concerns about the presence of the 225 kV high voltage power line between Kadéni and Pa which is located near the site, in addition to the RN1 and a fibre optic line;

� The impact of the Project on the classified area Houndé forests;

� The impact of mining activities on the health of workers and local communities;

� The impact of mining activities on the artisanal gold mining activities;

� The occurrence of certain health problems; and

� The disturbance / degradation of morals.

Social and community impacts will arise in a number of key areas including:

� Loss of land;

� Loss of access to grazing;

� Inability to work on the mine site due to demographic, social and cultural restrictions;

� In-migration of skilled labour; and

� Development of local enterprises servicing the mine.

The most significant impact is likely to be the increased levels of income that arise from sources such as:

� Wages and salaries earned;

� Compensation received from loss of land; and

� Payments for services from local small businesses.

The increased levels of income will advantage those in receipt of the payments but adversely affect those who have not had the advantage, directly or indirectly of those increases in income.

The key offsets available will be those arising from training of people who cannot immediately seek or gain employment on the mine to give them skills required to gain benefit from the mine indirectly, through service supply.

The community development programme will also contribute to reduction of the social impact.

20.4 Anticipated Land Acquisition and Relocation Costs

The mine will need to acquire 2,096 ha to provide space for the open pit, processing plant, waste piles, TSF, water harvest dam and water storage dam, as well as the necessary roads. However, most access roads will use existing pathways and upgrade them as necessary. As well, a 250 metre wide health perimeter around the existing infrastructure has been delineated to ensure that those that may be impacted by the mine the most (dust, noise etc.), have the option of receiving compensation and moving to another area. A further compensation perimeter, designated as a mitigated 50 dB(A) night time sound perimeter has also been delineated to provide a mechanism for those impacted by the mine noise the option of being compensated and moved to another location further from the mine.

In order to evaluate what fair compensation entails, a detailed study of the local inhabitants, cultural property, land use, land productivity, trees, replacement land, local businesses and replacement structures was carried out by SOCREGE under the supervision of Genivar. In conjunction with this study, Endeavour also reviewed land productivity, crop selection, yearly crop prices and crop selection. This work then provided a range of compensation options dependent on the individual compensation circumstances. For this study, fair baseline compensation was determined for the following major items:

� For farm land

- a combination of cash and crop compensation that totals up to 5 years crop value at Houndé regional productivity for a particular farm plot

- access to replacement land if desired.

� For habitations and out buildings

- replacement with same or better homes in an area of their choosing with a study bias toward the nearby community of Houndé

- cash or in-kind compensation for out buildings that would not be used any more.

� Cultural property (graves, ceremonial sites, archaeological sites and household fetishes)

- mixture of ceremony fees and direct cash compensation.

� Re-establishment costs.

� Cash compensation or re-planting for crop trees and other trees.

� Cash compensation for small businesses in the impact zone.

The process of determining the appropriate level of compensation is still proceeding with total compensation levels ranging from $6.2 million to $15.8 million. For the purpose of this study, an overall compensation level of $12.0 million was chosen. Details for the various compensatory items are contained in the Resettlement Action Plan study.

20.5 Anticipated Cost – Closure

The estimate cost of closure is US$26,384,000 (see Table 21.3.7, including Contingency). This cost is based on a combination of resale, reuse, recovery and rehabilitation options for the facilities as described in earlier Sections. The biggest single cost will be the cost of closure of the tailings storage facilities. This cost does not include provision for ongoing monitoring that may be required after closure and rehabilitation works have been completed. It is expected these could require ongoing monitoring of US$175,000/y, if required by the regulatory authorities prior to acceptance of relinquishment.

The objective of the mine closure will be to provide landforms that can be utilized by the community without liability to the community to generate an ecologically sustainable landscape post-mining. The present dependence of the community on cash crops and subsistence farming suggests that the closed mine should provide landforms which are capable of being grazed by animals or supporting annual or perennial crops. Given the sensitivity to water availability in the area, any water dams should be retained for use by the community and any water management structures that can increase water storage capacity for the community would be seriously considered.

Any saleable items will be recovered from the site. Buildings and infrastructure will be offered to the community for use and any materials suitable for recycling will be sold.

All contaminated land will be remediated either by placement of a soil / rock cover system over the area (such as with the TSF) or through removal of the contaminated material to a designated landfill area and replacement of the soil with rock waste and a topsoil cover.

Provision has been made to batter down waste rock dumps and cover their surfaces with topsoil collected during the construction and operations phase. Waste dumps will then be reseeded with local plant species to provide both a vegetated cover to control wind and water erosion and support any beneficial uses identified by the local community.

The pit voids will be left open but surrounded by a protective bund, outside the zone of instability, to ensure entry by vehicles will be hindered.

A rehabilitation fund is required to be set up upon opening of the mine. The funding for the rehabilitation fund will be set up to match total material movement in the mine with $0.10 /tonne mined added to the fund annually. Using this methodology, the closing balance will be $23.3 million, which will be topped up to $26.4 million (includes contingency) at closure. The details of the rehabilitation costs are as follows:

� Tailings - $ 14,505,000 (see table 20.5.1).

� Water pipeline removal - $60,300.

� Mining Services – wash bay demolition = $13,440.

� Process Plant demolition - $4,953,000

- demolish and sell steelwork structure

21.0 CAPITAL AND OPERATING COSTS

21.1 Mining Cost Estimates

Orelogy has estimated mining costs for the project on an Owner operated basis as summarised in Table 21.1.1.

Costs were built up from first principles in a detailed cost model utilising:

1. Heavy equipment capital and operating costs sourced from the relevant Original Equipment Supplier (OEM) during 3rd quarter 2013.

2. Productivity and equipment hours generated by EVORELUTION mine scheduling and haulage optimisation software, based on reasonable working productivity assumptions.

3. Personnel, fuel and power costs in line with those utilised by Lycopodium for the processing cost estimation.

21.1.1 Estimate Basis and Qualifications

The various cost items were then applied to the physicals of the LoM schedule to develop a mining cashflow schedule over the life of the operation. Mine scheduling work has been based on 300 tonne excavators loading 140 tonne trucks supported by a medium sized ancillary fleet.

The capital cost provided by the OEM is inclusive of sea freight and delivery to the Houndé site. Additional allowances for the following have been included:

� Additional equipment (e.g. water tanks for water truck).

� First fill spares component at 1% of F.O.B cost.

� Initial truck tires are included in the capital expenditure, and the costs of subsequent tires are allocated to the operating cost.

A fuel price of $1.312/L was used for pre-production and this was increased to $1.40/L for LoM.

21.2 Process Plant and Administration

21.2.1 Summary

Process plant and administration operating costs have been developed by Lycopodium and Endeavour based on a design treatment rate of 3.0 Mt/y of ore with the plant operating 24 hours per day, 365 days per year with a 91.3% plant utilisation (nominal 8,000 hours per year) and a P80

grind size of 90 μm.

The operating cost estimate has been compiled from a variety of sources and is based on the Life of Mine (LOM) blend of 82% primary, 11% transition and 7% saprolite ores and a head grade of 2.0 g/t Au ore.

Operating costs are presented in United States dollars (US$) and are based on prices obtained during the third quarter of 2013, to an accuracy of ±15%. The process plant operating costs for the

21.3 Capital Cost Estimate

21.3.1 Summary

Lycopodium has prepared capital cost estimates for the project which are summarised as shown in Table 21.3.2. Mining costs were supplied by Orelogy, while Lycopodium compiled the remainder of the estimate, with quantities for infrastructure earthworks (TSF, water dams, surface water management structures) provided by Knight Piésold.

The exchange rates shown in Table 21.3.1 have been used in the preparation of the estimates. The table also shows the proportion of each currency used in the estimate.

The estimate accuracy is considered to be ±15%, as at 3Q2013.

Mining capital costs include the procurement and assembly of the mining fleet, detailed mine planning and prestripping operations needed to open up sufficient ore to be able to meet the mill demand once processing commences. The mining schedule indicates that three months of prestripping will be required.

21.3.2 Estimating Methodology

General arrangement drawings and a layout 3D model have been produced with sufficient detail to permit the assessment of the engineering quantities for earthworks, concrete, steelwork, mechanical and electrical for the crushing plant, processing plant, conveying systems and infrastructure. The layouts and model have been based on recently completed facility designs, modified construction and as-built drawings of past project facilities, as well as initial concept drawings and computer modelling.

Unit rates that reflect the current market conditions have been established for bulk materials, capital equipment and labour via an extensive Budget Quotation Request (BQR) process. Labour rates from the market have been benchmarked against in-house labour gang rates and indirect cost modelling to ensure adherence suitability to the current projects market. The rates used in the estimate have been reviewed and deemed to reflect the current market conditions. Budget pricing for equipment and infrastructure facilities was obtained from suitable suppliers and contractors.

The derivation of quantities is provided in Table 21.3.3, weighted by value of the direct permanent works (i.e. excluding temporary works, construction services, commissioning assistance, EPCM costs, escalation and contingency).

� Database – Historical database pricing that is less than 6 months old.

� Estimated – Historical database pricing older than 6 months, escalated to the current estimate base date.

� Factored – Factored from costs with a basis.

The source of pricing by major commodity is summarised in Table 21.3.4, weighted by value of the direct permanent works (excluding temporary works, construction services, commissioning assistance, EPCM costs and contingency), including supply and installation.

Pricing has been categorised by the following cost elements, as applicable, for the development of each estimate item.

Bulk Materials

This component covers all other materials, normally purchased in bulk form, for installation on the project. Costs include the purchase price ex-works, any off-site fabrication, and transport to site (unless otherwise stated), and over-supply for anticipated wastage.

Plant Equipment

This component represents prefabricated, pre-assembled, off-the-shelf types of mechanical or electrical equipment item. Pricing is inclusive of all costs necessary to purchase the goods ex-works; generally excluding delivery to site (unless otherwise stated) but including operating and maintenance manuals. Vendor representation and commissioning spares have been allowed for separately in the estimate.

Installation

This component represents the cost to install the plant equipment and bulk materials on site or to perform site activities. Installation costs are further divided between direct labour, equipment and contractors’ indirect costs.

The labour component reflects the cost of the direct workforce required to construct the Project scope. The labour cost is the product of the estimated work hours spent on site multiplied by the cost of labour to the contractor inclusive of overtime premiums, statutory overheads, payroll burden and contractor margin.

The equipment component reflects the cost of the construction equipment and running costs required to construct the Project. The equipment cost also includes cranes, vehicles, small tools, consumables, PPE and the applicable contractor’s margin.

Contractors’ indirect costs encompass the remaining cost of installation and include items such as offsite management, onsite staff and supervision above trade level, crane drivers, mobilisation and demobilisation, Rest and Recreation (R&R), meals and accommodation costs, and the applicable contractors’ margin.

The labour gang rates, equipment and contractor’s indirect costs estimated for each major trade commodity are shown in Table 21.3.5.

Table 21.3.5 Standard Direct Labour Gang Rates

Item Direct Labour $ Equipment $ Total Hourly Rate $

Concrete Installation 5.00 2.00 7.00SMP 15.00 8.00 23.00 Field Erected Tanks 15.00 8.00 23.00 Building Installation 12.50 5.00 17.50 Electrical & Instrumentation 8.20 12.00 20.20

Generally, for bulk commodities the lowest cost vendor and contractor rates were used in the estimate.

Freight

The freight estimate was derived:

� from the assessment of freight tonnes or bulk volume and number of containers from the quantities derived in the capital cost estimate and vendor supplied shipping lists and advice

� from the most likely country of origin

� from the application of rates used for recent similar projects for pre-shipment, ocean freight and post-shipment overland freight.

21.3.3 Field Indirect Costs

Project construction offices and establishment, communications, computers, IT services, servers and telephones are included in the capital estimate. Construction services such as power, water, fuel, consumables and personal protection equipment (PPE) are included.

The estimate includes costs for meals and accommodation for senior staff over the construction duration.

The capital estimate includes the cost of local indirect labour for installation support.

Contractor indirect costs for all direct labour is included in the installation rates for all works in the capital estimate. This is inclusive of meals, accommodation, PPE, flights and clothing. Earthworks rates are inclusive of fuel, maintenance and running costs of machinery also.

Construction fuel facilities will be provided by the individual construction contractors.

Construction equipment and project cranes (excluding heavy lift craneage) are included in the capital cost estimate.

21.3.4 EPCM Services

The estimate for Engineering Procurement and Construction Management (EPCM) services costs has been based on a preliminary manning schedule for the anticipated project deliverables and project schedule. The resulting EPCM cost estimate is consistent with other projects of this nature in terms of the percentage of the direct costs.

The engineering design component of the EPCM estimate for the home office is based on a calculation of required manning levels to complete the Project and benchmarked against previous Lycopodium experience on similar projects.

21.3.5 Owner’s Costs

As part of the construction, Endeavour will provide a Project management team.

The Owner’s construction team will interact closely with operations management personnel recruited during the construction phase of the Project.

Endeavour has successfully developed several projects in the West African region and has elected to procure the mills and free-issue these to the EPCM contractor, as well as supervising much of the earthworks and infrastructure works to the EPCM contractor’s design. Because of this approach, the Owners’ cost allowances in the above estimates are relatively high compared with a “pure” EPCM approach.

In addition to the above, the following allowances have been made in the estimate.

� Owners project expenses.

� Pre-production costs.

� First fills (grinding media, lubricants, fuel, and reagents).

� Opening stocks.

� Plant mobile equipment.

� Project spares.

� Vendor representative and training costs for the process plant.

� Asset management system implementation, training and software.

� Crop compensation and resettlement costs for the first year of construction.

� Connection to the power grid and associated engineering costs.

� Environmental cost allowance.

� Working capital.

Spares and Insurances

An agreed allowance has been included for spares. Project insurances have been included, based on advice from Endeavour.

21.3.6 Contingency

An amount of contingency has been provided in the estimate to cover anticipated variances between the specific items allowed in the estimate and the final total installed project cost. The contingency does not cover scope changes, design growth, etc., or the listed qualifications and exclusions.

Contingency has been applied to the estimate on a line-by-line basis as a deterministic allowance by assessing the level of confidence in each of the defining inputs to the item cost, these being engineering, estimate basis and vendor or contractor information, and then applying an appropriate weighting to each of the three inputs. It should be noted that contingency is not a function of the specified estimate accuracy and should be measured against the project total that includes contingency.

A summary of contingency percentage for the major horizontal packages is provided in Table 21.3.6.

Page 21.18

October 2013 Lycopodium Minerals Pty Ltd

� The bulk commodity rates that include for imported material are based on the assumption that suitable construction / fill materials will be available from borrow pits within 2,000 m of the work fronts.

� The estimate includes for the placement and compaction of fill material to the crushing chamber wall to a horizontal distance of 3 metres only. ROM pad earthworks construction costs have been allowed in the mining cost estimate.

� The estimate allows for all reinforced bar and mesh for construction to be provided by the concrete contractor. Free issue of materials would be a project capital opportunity and has not been allowed at this time.

� There is no allowance for unforeseen blasting in the bulk earthworks cost estimates, given the results of the site geotechnical investigation. There is an allowance for part of the bulk earthworks balance to be imported fill in the unforeseen event that the in-place material is unsuitable.

� Mobilisation / demobilisation of a roadworks contractor has not been allowed as it is assumed the plant earthworks contractor can complete the works. Duration costs have been included.

� The estimate allows for supply of structural steel and minor platework from South East Asia. The rates for structural steel supply are based on recent project costs.

� The estimate allows for one piece tanks and large platework items to be fabricated in country as the freight cost for these items from South East Asia makes this option uneconomical.

� Supply and installation of field erected tanks will be by a suitable in-country contractor. There is no allowance for free issue of strakes and materials to the installation contractor. This is a project capital opportunity and has not been included at this time.

� Supply of construction and potable water prior to completion of the water harvest dam will be from the existing site supply. The capital includes for the mechanical costs and installation of one additional bore pump at the location of the permanent village; however, there is no allowance to drill and case a bore in the estimate. The locations of the additional bores have not been defined at this time and the cost of establishing further water sources is not included.

� The supply of the SAG and Ball mills has been included in Owner’s costs.

� The estimate excludes for a construction camp. The permanent camp will be constructed as early as practical and until such time as it is available for use, construction personnel will be accommodated in Houndé town.

� Owner’s mobile equipment for construction and operations is included.

� Asset management software for operations is allowed for in the capital estimate. Software implementation and training costs are included.

� There is an allowance for surveying to be performed by the Owner’s team.

� Mining contractor facilities are included in the capital costs.

21.3.9 Exclusions

The following items are specifically excluded from the capital cost estimate:

� Permits and licences (except as listed).

� Project sunk costs (these are addressed in the financial model.

� Government and import taxes and duties (these are addressed in the financial model).

� Exchange rate variations.

� Escalation.

21.4 Project Implementation

21.4.1 Implementation Strategy

The cost estimates have been complied on the basis that Endeavour will adopt an EPCM approach, in which a small Owner’s team will manage several specialist engineers and consultants, who will carry out the detailed engineering, procure the equipment and fabricated items and manage the installation contracts. The EPCM engineer will be appointed on a schedule of rates basis, this arrangement permitting Endeavour to have maximum input to the quality of engineering and equipment procured for the project with a minimum Owner’s team and securing the services of specialist designers and project management expertise.

21.4.2 Implementation Schedule

The project implementation schedule has been developed on the basis that no early procurement works will be conducted – i.e., that engineering will only commence after full project approval has been secured from the Board. A high level schedule has been prepared on this basis and is shown in Figure 21.4.1. The overall duration of the project from Board Approval to first gold is estimated to be 21 months.

1813.20\25.01\1813.20-STY-001_B S21

Page 21.20

October 2013 Lycopodium Minerals Pty Ltd

The project critical path shown in Figure 21.4.2 runs from the award of the EPCM contract through the process and detailed design to mill building structural steel supply, erection of the milling building and installation of the equipment before final completion of the piping and electrical activities to allow commissioning to proceed. The schedule is based on purchase orders for the SAG, ball and UFG mills being placed immediately the project is approved; if these orders are delayed, the critical path then shifts to the mills procurement and delivery. The mining fleet and HV power equipment also require engineering and procurement activities to commence immediately on project approval in order to meet the overall schedule of 21 months.

21.4.3 HSEC Management

The management of health and safety as well as the environment and local community (HSEC) are critical for any successful project development. The EPCM Engineer will develop a project management plan to address these issues, based on their standard procedures, project construction experience and the risks and hazards identified during the feasibility and design stages, all through the project construction to commissioning and hand-over.

21.4.4 Logistics

Equipment will be sourced from vendors on the basis of price and delivery; such vendors typically fabricate components in many different countries. Fabricated steelwork and platework will be sourced from Africa or SE Asia, again on the basis of price, delivery and quality. The EPCM engineer will engage a logistics and transport coordinator to consolidate freight items where possible and facilitate clearance through customs and transport to site. Where practical, containerised items will be transported by rail, with the remainder transported to site by truck. Oversize loads will receive special attention and escorts as applicable.

21.4.5 Training

Endeavour is an operating company with well-established training procedures. The EPCM engineer will assist Endeavour to train its operations staff during the commissioning period and thereafter as needed, to ensure a smooth transition from construction to operations.

22.3 Principal Assumptions

The cash flow analysis is based on the following:

Basis of Estimate

� Annual tonnage, strip ratio and head grade have been based on the mining schedule as discussed in Section 16.

� The mining, processing and administration costs are based on the operating cost estimate discussed in Section 21.

� The overall recovery figures are based on testwork. Metallurgical recovery is discussed in Section 17.

� The capital cost estimate used as basis for the cash flow model is discussed in Section 21.

� The treatment of depreciation and company taxes are based on the understanding of current Burkinian tax law.

Depreciation

� Provision has been made for depreciation using a straight line method for a period of 4 years.

� The schedule allows for $30 million of losses carried forward at the start of the operation.

� In the final year of operation, the residual capital allowance outstanding is depreciated against the salvage value of the plant.

Company Tax

� Provision has been made for company tax at 17.5% of gross profit. This is the rate of corporate tax in Burkina Faso.

� Tax losses that can be carried forward have been ignored

Gold Price

� A gold price of $1,300 per ounce is assumed based on advice from Endeavour.

� A refinery gold payable rate of 99.95% is assumed.

� The refining charge of $3.35 per ounce of gold was advised by Endeavour to include the cost of transport and insurance of the gold from site to the refinery.

1813.20\25.01\1813.20-STY-001_B S22

Page 22.5

October 2013 Lycopodium Minerals Pty Ltd

Royalties

� Royalties are allowed at 4.0% of revenue for the Burkina Faso Government and 2.0% for African Barrick.

General

� The cash flow model assumes full equity funding.

� No provision has been made for interest or cost of capital.

� No provision has been made for escalation or inflation, other than to allow for labour costs to increase by 3% as from Year 4, which represents an apprentice surcharge levied by the government of Burkina Faso at the mid-point of the mine life.

� Closure and reclamation costs have been allowed as an annual contribution to a Trust Fund of $0.10 per tonne of material mined over the life of the mine, with a top-up payment at the end to cover the estimate total costs of rehabilitation.

� No provision has been made for additional taxation or costs related to the repatriation of funds from Burkina Faso.

� The NPV calculation is based on payments occurring at the end of each period. The cost of the first year is discounted, based on the assumption that there will be some delay in spending the capital from present.

� Working capital has been included in the capital cost estimate.

� Allowance has been made in the capital costs for Import Duties at the rate of 2.5% on an amount of $180 million, representing an approximate value of the goods and services to be imported.

� An allowance for Import Duties has also been made in the operating cost schedule of 7.5% on 50% of the operating costs for mining, processing and G&A.

� The cash flow calculations have been prepared on an annual basis; where shorter periods have been used in the mining schedules, these have been totalised to annual costs based on Project years.

22.4 Processing Costs and Production Schedules

22.4.1 Mine Production Schedule

Annual tonnage, strip ratio and head grade is based on the mining schedule developed by Orelogy (refer to Section 16).

HOUNDÉ GOLD PROJECT, BURKINA FASO FEASIBILITY STUDY NI 43-101 TECHNICAL REPORT

1813.20\25.01\1813.20-STY-001_B S22

Page 22.6

October 2013 Lycopodium Minerals Pty Ltd

The mining schedule assumes three months of pre-strip prior to the start of production. The schedule allows for mining and stockpiling of ore to provide more consistent mill feed. The stockpile varies from a high of 0.5 Mt at the end of Year 4 to a low of 40 kt in Years 5 and 6 with an average of 0.23 Mt. During the last years of production, stockpiled low grade material will be treated, allowing for just over 9 years of mill production. Figure 22.4.1 shows the mining schedule upon which the cash flow model is based, while the processing plant feed tonnages are indicated in Figure 22.4.2.

22.4.2 Operating Cost

Figure 22.4.3 presents the contribution of mining cost, processing cost, general and administration cost. This does not include smelting and refining costs, rehabilitation and closure costs which are incurred at the end of production or royalties.

Figure 22.4.3 Operating Cost Contribution (US$/oz Recovered & %)

Capital Cost

The capital estimates are detailed in Section 21. Table 22.4.1 shows the annual capital cost schedule used as the basis for the cash flow model.

Owner’s Cost

The Owner’s project cost includes the cost of procuring the mills as well as the costs for carrying out the earthworks contracts, land acquisition and resettlement costs.

Deferred Capital Cost

Deferred and sustaining capital costs cover the requirements for mining fleet expansion and equipment replacement over the life of the mine, as well as development costs for new pits.

The TSF embankments will need to be raised regularly over the life of the mine and costs are allowed for these raisings; at the end of the mine life, the TSF must be rehabilitated and costs are allowed for this action, which is described in Section 18.

Sustaining capital has also been allowed to replace mobile equipment and IT systems needed for the processing plant and administrative services and final rehabilitation of the processing facilities at the end of the mine life.

Page 22.8

October 2013 Lycopodium Minerals Pty Ltd

Working Capital

The Owner’s Operations Costs cover the working capital requirements for four weeks until revenue is received from the first bullion shipment. No allowance has been made to recover the working capital at the end of the mine life.

Plant Salvage

An allowance has been made for salvage of the mining equipment and process plant, for a nominal value of $5 million.

22.5 Outcomes

22.5.1 Base Case

At a gold price of $1,300 per ounce and full equity funding, the Project is estimated to have an after-tax IRR of 22.45% and a pay-back period of 2.84 years. At a discount rate of 5.0%, the after-tax NPV of this scenario is estimated at $230.2 million.

Cash Flow Analysis

The undiscounted annual cash flow is summarised in Table 22.5.1. This shows that the project is expected to be cash flow positive from the first year of operation, while project payback is achieved at the end of year 2. The undiscounted net present value of the project (after tax) is $364.2 million.

23.2 Yaramoko – Roxgold Inc.

The Yaramoko property is controlled by Canadian listed Roxgold Inc. The property lies approximately 40 km northeast of the Vindaloo zone, along the eastern edge of the Houndé volcanic belt. The deposit is structurally controlled and hosted by a mixture of granite and volcanic rock. According to a presentation from April, 2013 the property hosts 639,951 ounces Indicated Mineral Resources at 19.3 g/t Au and 183,894 ounces Inferred Mineral Resources at 11.5 g/t Au at a 5 g/t Au cut-off. This Mineral Resource estimate is based on 216 holes to a depth of 800 metres. A PEA is due in Q3, 2013.

23.3 Houndé South – Savory Capital Corp.

The Houndé South property is controlled by Canadian-listed Savory Capital Corp. (Savory). This property is optioned from Endeavour Mining. In order to earn a 100% interest in the property, Savory needs to spend $3 million on exploration by mid May, 2014 and give Endeavour shares totalling up to an interest of 19.9% of the company. The property is located approximately 45 km southwest of Endeavour’s Houndé property.

‘The Houndé South concessions are underlain by a northerly-trending package of mafic to intermediate composition volcanics and sediments that are intruded by a mix of early to late felsic to mafic intrusions. These rocks have been deformed and subjected to local shearing and faulting. Property-scale airborne magnetic data indicate strong, north-trending lineaments that are interpreted to represent shear zones or large fault zones, lie to the east and west of the known zones of gold mineralization. Less well defined magnetic lineament correlate well with the gold occurrences and gold-in-soil anomalies.’ excerpt from Savory’s 43-101 report, Armstrong et. al., 2012.

Savory has carried out two drill programs since acquiring the property option. The drilling has confirmed the existence of some of the historic gold mineralization and resulted in the discovery of two new zones, one of which returned an intercept of 11.16 g/t Au over 9.0 metres (news release May 9, 2013).

23.4 MM Prospect – Sarama Resources Ltd.

The MM prospect, which is located on the Tankoro property, is owned by Canadian-listed Sarama Resources Ltd. The property is located approximately 60 km south of Endeavour’s Houndé property.

During 2012, Sarama completed 80,000 metres of RC, diamond and RAB / air core drilling and outlined a 30 km long mineralized structural corridor. Within this corridor, two 2 km long mineralized zones were discovered in the MM and Phantom zone areas. Gold mineralization in these areas is mainly associated with strongly altered feldspar porphyry dykes. Significant results include 10.2 metres at 14.85 g/t Au, 15.50 metres at 6.61 g/t Au, 11.8 metres at 8.06 g/t Au, 13.9 metres at 14.47 g/t Au, 18.3 metres at 7.09 g/t Au and 13.9 metres at 5.90 g/t Au. A maiden Mineral Resource estimate is expected in Q3, 2013.

23.5 Bondigui – Orezone Gold Corporation

The Bondigui Property is owned by Orezone Gold Corporation. It is located approximately 30 km due south of Endeavour’s Houndé property within the Houndé greenstone belt.

The gold mineralization at Bondigui is chiefly associated with a north to north-northeast striking, sub-vertical shear zone array, accompanied with discrete shears splaying off along 330/60°E, 000/90°, and 035/80°E. The system has been interpreted as a dextral shear zone with second and third-order shears. The individual shear corridors are 5 to 50 m wide.

The mineralization lies in a shear zone cutting across the eastern contact of the Tarkwa sedimentary trough within the eastern volcanic domain and is in close spatial association with mafic and intrusive bodies.

Mineralization is characterized by alteration that manifests itself by silicification, sericite, carbonate (ankerite), and hematite, with occurrences of finely disseminated pyrite. The sulphide abundance amounts to 1 to 2% (locally 5 to 10%) and is dominantly represented by pyrite, with subordinate arsenopyrite and chalcopyrite.

Veins and veinlets ranging from 0.1 – 1.0 m found with the alteration in the shear zone form mineralized bodies up to 24 m wide.

A NI 43-101 compliant report titled ‘Technical Report on the Mineral Resource of the Bondigui Gold Project’ was published in February 2009 on SEDAR. The deposits hosts Measured and Indicated Mineral Resources totalling 4,140,000 t at 2.12 g/t Au (282,000 oz Au), whereas the Inferred Mineral Resources were 2,536,000 t at 1.84 g/t Au (149,700 oz Au).

23.6 Dossi – ACC Resources

The Dossi property is owned by ACC Resources. It is situated immediately east of Endeavour’s Houndé licenses (Figure 23.1) within the Houndé greenstone belt. ACC carried out several exploration campaigns, including the following:

� 227 RC drill holes (27,827 m),

� 31 Core holes (4,676 m) in Zone 1,

� 800 RAB drill holes (20,910 m),

� 2,827 soil geochemistry samples,

� Four ground geophysical programs (IP), and

� High resolution aeromag and radiometry (Fugro Airborne Surveys, MIDAS) completed in November 2010.

The company has not publically reported a mineral resource estimate.

23.7 Mana Mine – Semafo SARL

The Mana mine is operated by SEMAFO SARL. It is situated approximately 40 km North of Endeavour’s Houndé licenses.

The Mana property is mostly covered by Houndé greenstone belt sedimentary, volcano-sedimentary, and volcanic rocks of Birimian age.

SEMAFO has discovered seven areas of gold mineralization within 20 km of the mill including Wona, Nyafe, Filion 67, Fofina, Yaho, Fobiri and the newest, Siou. Six of these zones have reported mineral resources.

The Wona deposit is hosted in a series of highly deformed sedimentary (black pelites), volcano-sedimentary, and meta-volcanic rocks. The gold mineralization developed along a major northeast-trending sub-vertical fault zone of regional extent. The zone is up to 200 metres wide in the Wona pit sector. The original stratigraphic sequence is a succession of pelitic sediments with graphitic horizons and volcaniclastics. The rocks have been affected by a pervasive S1 schistosity, which would be associated to vertical movements along the fault (i.e., the east block rising with respect to the west one) as well as sinistral lateral movements. These foliated rocks are cut by mafic to intermediate dikes, themselves foliated (i.e., S2 schistosity parallel to S1).

The mineralization itself would be associated to a posterior lateral movement along the fault with hydrothermal fluid circulation and intense silicification.

The Nyafé deposit is hosted in a purely volcanic sequence with basalt and mafic to intermediate tuffs and flows. Pillows display a dark ferrous chloritic border suggesting some hydrothermal alteration of volcanogenic origin. Several sub-vertical decametric dikes cross the volcanic sequence, in particular a N-S felsic quartz porphyritic dike and two mafic dikes on both sides of the pit parallel to the mineralization.

The Filon 67 deposit, next to Nyafé is comprised of greenschist-hosted quartz veins that are associated with shear zones with dextral movement. These composite veins demonstrate multiple episodes of crack and fill textures.

As is the case for outcropping mineral deposits in tropical climate zones, in western Africa in particular, the rock package hosting both Wona and Nyafé deposits has been subjected to intense meteoritic alteration with the development of a saprolitic zone near the surface.

The Wona deposit has been traced over a distance of 4.7 km along an azimuth of 46°. The Nyafé deposit extends for 2.4 km along a N-S direction.

The Filon 67 or F67 ore body lies almost parallel to the Nyafé ore body, about 300 m to the east. It strikes almost NS over a length of about 500 m.

Siou is hosted by a shear zone that lies along the contact between granodiorite and sediments.

24.0 OTHER RELEVANT DATA AND INFORMATION

24.1 Risks and Opportunities

In addition to the risks and opportunities outlined in the sections above, a workshop was conducted to identify high level sources of uncertainty that could influence the Project outcome. The workshop was attended by representatives of the organisations contributing to the Report and was facilitated by an experienced person independent of the study teams. The workshop identified both risks and opportunities, evaluated likely scenarios and rated these in terms of likelihood of occurrence and severity of consequences. The resulting level of risk for each item was then evaluated and a decision made to accept the risk or implement additional mitigating measures. The Risk Register arising from the workshop is attached in Appendix 24.1.

24.2 Other Relevant Data

There is no other data relevant to the Houndé Project that has not already been discussed in this report.

25.0 CONCLUSIONS

Detailed conclusions arising out of the performance of this Study have been utilised in the development of the relevant sections of this report. This section considers more general aspects of the study.

25.1 Conclusions

� Exploration drilling in the immediate Vindaloo and Madras NW pit areas indicates that there are both in-pit and near pit mineralized zones that merit follow-up in the short term, as their delineation could have a positive impact on the current mine and waste pile models.

� Exploration targets, located around the periphery of the Vindaloo and Madras NW pits, have the potential to add additional reserves.

� The Vindaloo mineralisation is sufficiently drilled and modelled to allow classification into a Resource Model that has been developed using generally accepted industry techniques and practices and conforms to CIM guidelines (CIM 2005). The Mineral Resource estimate is reported at a cut-off grade of 0.35 g/t Au with an effective date of July 18, 2012.

� The metallurgical testwork conducted on samples representing the bulk of the deposit to be mined has resulted in the development of a robust process flowsheet which is expected to recover in excess of 93% of the gold in the mill feed. Additional testwork on gravity concentration would improve the confidence of the design details and recovery estimates for this part of the process, and further testwork to optimise cyanide consumption may lead to reductions in overall operating costs.

� The mine design and scheduling activities have resulted in a Reserve statement produced in accordance with Canadian National Instrument 43-101, ‘Standards of Disclosure for Mineral Projects’ of June 2011 (the Instrument) and the Definition Standards adopted by CIM Council in November 2010.

� The preliminary design of the supporting infrastructure for the project has been carried out in sufficient detail to arrive at cost estimates of appropriate accuracy for study of this nature. One item still under negotiation is the connection to the HV power grid; while SONABEL has agreed in principle to supply power to the project, the details of the connection have not yet been agreed.

� Environmental studies have established the baseline conditions in the local project area and the efforts to mitigate the environmental impact of developing, operating and closure of a mine. The ESIA Reports have been completed and the Resettlement Action Plan is nearing completion to support the application for permits.

26.0 RECOMMENDATIONS

Specific recommendations arising out of the performance of this Feasibility Study have been identified and recorded in the relevant sections of this report. This section considers more general aspects of the study.

Given the favourable economics of the project, it is recommended that Endeavour proceed with development of the project.

An exploration plan should be developed that matches the mine development schedule to ensure that any mineralized zones that could positively impact the mine plan, are delineated in sufficient time to allow for the development of an updated mine plan.
