SUMMARY

A scope of work was initiated and approved in January-February 2014 to undertake a spinner logging (Hydrogeology) and core drilling (Delineation) program. The former aimed to supplement or update previous Victor hydrogeological information necessary to develop a new regional groundwater flow model for the Victor Mine Extension Project while the latter aimed to test for flaring in the shallow portion of the Tango Extension pipe and geotechnically investigate the overburden in the area for a future trench/pit. During the months of March and April 2014, the following holes were drilled: two monitoring wells, a pump test well, two delineation holes, and one overburden hole. Collectively, a total of 809.74 meters were drilled within CLM 456 and 109496 claims. The hydrogeology holes were completed utilizing a Foremost dual rotary drill rig (DR-24HD) while the delineation holes were accomplished by employing De Beers’ owned Zinex A5-2 drill rig. Hydrogeology drilling was carried out by LBM (Les Forages LBM, Victoriaville QC) while Foraco (Foraco Canada, North Bay, ON) undertook delineation drilling. Project supervision and field geological logging for all holes were performed by De Beers’ staff. Golder Associates undertook overburden logging/sampling for geotechnical analysis. Ice thickness assessment necessary for access and drill pad preparation were contracted to Ausenco while hydrogeological drilling result interpretation was made by Itasca Consultants. The total project expenditure was CAD $1,546,475.00. The drilling program was completed with 0 LTI (Lost Time to Injury), 0 First Aid case, 0 incident requiring medical treatment, 0 incident causing damage to equipment, and 3 minor environmental incidents which were all reported and cleaned up.

Assessment Report 2014 CLM 436, 109496 De Beers – Mining Canada

1.0 INTRODUCTION This assessment report discusses the work undertaken by De Beers Canada Inc. on the Tango Extension Kimberlite and vicinity, specifically, within CLM 436 and 109496 leases for the period January to April 2014. The objectives of the program were:

a. To conduct spinner log testing of two drillholes, North and South of the kimberlite as well as completion of a pilot hole to the east of the kimberlite for a future large diameter pump test well or permanent pump installation; and

b. Core drilling aimed at testing pipe margins for flaring, determine the kimberlite unit to be sampled by future trenching, and establish the exact depth to kimberlite in the trench location. In addition, it was aimed to investigate (geotechnical) the overburden in the area of the proposed trench.1

1.1 Location and Access

Tango Extension kimberlite forms part of the Attawapiskat Kimberlite Province located 90 km west of the community of Attawapiskat, Ontario, which sits on the western coast of James Bay. It is situated approximately 6.5 km north-northwest of the De Beers’ Victor mine, and at its closest, approximately 2 kilometers west of the Attawapiskat River.

All of the claims are 100% owned by De Beers Canada Inc.

1.3 Topography and Drainage

The Tango Extension work area is situated within the Attawapiskat Watershed and is defined by a gently sloping topography that drains northwards into the Attawapiskat River, which ends at James Bay. The terrain is poorly drained due to the very low permeability of the marine silts and clays, and this same characteristic has allowed for the creation of aquifers at depth within the limestone sediments. Most of the small creeks barely dissect the terrain and are therefore isolated from the deeper groundwater aquifer.2

1.4 Climate and Vegetation

The James Bay lowlands have a subarctic to humid continental climate with long, cold winters and short, warm summers with low annual precipitation (Rameseder, 2007). Weather data (i.e. average daily temperatures recorded during the program) as obtained from Victor’s Mine Environmental Group is presented in Table 2 and Figure 5. The vegetation is mostly coniferous with typical sub-arctic and boreal plants.

1.5 Planning, Permits and Environmental Management

The 2014 winter drilling program at Tango Extension was initiated, with approval, late in January 2014 following discussion with DBC Global Mining. Initial scope was to proceed with a three hole spinner logging program, however, in February additional scope was requested to consider to undertake limited core drilling as a test for flaring in the shallow portion of the pipe and also to geotechnically investigate the overburden in the area of the proposed trench, while also assessing the geotechnical aspect of the mudstone unit to the SW of the pipe for geotechnical characteristics and pit slope estimation3.

Permits and notices to drill were obtained prior to the program’s commencement and extended across the entire duration of the drilling activities. Notices include - Notice of Operation of a Core Drill and Notice of Project and Extended hours. Permits to take water and to discharge water were applied and subsequently granted by the Ministry of Environment on March 14, 2014. As an additional permit compliance item, an Operating Manual was developed and implemented for the pumping and discharge operation.

As part of De Beers’ ISO 14001 Environmental Management System (EMS) all work programs are required to adhere to all regulatory Acts, legislation and guidelines as they apply to waste management, storage and disposal. An Emergency Response Plan specifically for the 2014 program was developed. During the drill program, a SHE coordinator was engaged to supervise and support SHE programs of De Beers. Specifically, the following activities were carried out: a) Developed Safe Work Plans (SWP) b) Daily and weekly site inspections; c) Daily toolbox and weekly SHE meetings; d) Environmental site inspection and sign-off on all drill sites; e) Fire extinguishers, first aid kits, spill kits and eye wash stations were made available

at the drill sites and are regularly inspected; and

f) Submitted daily reports on fuel consumption and water take records by drilling crew to Environment Department.

In addition, all personnel working on the program have undergone the following training (as required):

1. WHMIS 2. TDG – if working with or Transporting Dangerous Goods 3. Chainsaw license (only for personnel using chainsaws) 4. Spills containment and response (orientation/environment training modules) 5. Common Core – drillers and supervisors 6. Exposure to Exploration operating procedures relating to job activities (read/sign-off)

As a result, the drilling program was completed with 0 First Aid cases, 0 Medical Aid, 0 incident causing damage to equipment/property, and 3 minor environmental incidents which were all cleaned up and reported.

2.0 GEOLOGY 2.1 Previous Mapping

The Tango Extension kimberlite is within the so-called Attawapiskat kimberlite cluster (a cluster of 22 kimberlites) discovered in the late 1980’s. Eighteen (18) of which fall under the De Beers held claims and 4 lie within the KWG Resources held claims. All 18 kimberlites held by De Beers are diamondiferous, but little exploration work has been carried out on most, especially due to their small surface areas. The Attawapiskat kimberlites appear to cluster in a north-northwest elongated trend approaching 36 kilometers in length. Kimberlites discovered within the De Beers claims (refer to Figure 5) are: Alpha-1, Alpha-1 North, Bravo-1, Charlie-1, Delta-1, Golf-1, Golf Extension, India-1, Logan, Tango, Tango Extension, Uniform, Victor, Whiskey, X-Ray, X-Ray-1, Yankee and Zulu. The Victor kimberlite, currently under production and with reserves expected to have a mine life until the year 2018, has the largest surface area within the cluster at approximately 15 hectares.

The 4 remaining kimberlites fall under the KWG Resources. tenements and are: Good Friday, MacFayden 1, MacFayden 2, and MacFayden 2 south. Additional kimberlite bodies have been discovered by Navigator Resources on claims contiguous to De Beers (AT-56), but have been relinquished due to very small surface areas.

2.2 Regional Geology and Tectonic Setting

The Attawapiskat Kimberlite Province lies within the Western Superior Structural Province of the Canadian Shield. The Superior Province forms the core of the North American continent and is bound on all sides by cratons of Paleoproterozoic and Mesoproterozoic ages (Percival, Sanborn-Barrie, Stott, Helmsteadt, & Skulski, 2005). Current investigations indicate that the Superior Province is made up of a collage of tiny continental fragments of Mesoarchean age and Neoarchean oceanic plates with a complex history of aggregation between 2.72 and 2.68 Ga (Percival, Bleeker, Cook, Rivers, Ross, & Van Staal, 2004). The Superior Province is one of several Provinces that accreted and stabilized during the Wilson Cycle of “ocean closure” during the late Archean. These Archean Provinces are bound along their margins by structural

11 | P a g e

Assessment Report 2014 CLM 436, 109496 De Beers – Mining Canada

“orogenic belts” of varying ages and distinct geological and structural characteristics (Card & Ciesielski, 1986). The Superior Province is further divided into linearly fault-bounded sub-provinces each with their own distinct geological characteristics, age and metamorphic conditions. These sub-provinces host a variety of viable economic deposits in gold, diamonds, potash, copper, zinc, coal and other deposits. Most of these sub-provinces are contiguous to the Moose River Basin comprising Paleozoic and Mesozoic sedimentary cover, predominantly limestone and dolostone that have been intruded by kimberlites.

Figure 7. Regional Geological Setting (McCrae, 2003)

The kimberlite bodies are located on the southeast flank of the Cape Henrietta Maria arch that roughly divides the Hudson Bay platform rocks into the Hudson Bay basin to the northwest and the Moose River basin to the southeast. The arch has affected the distribution of ancient sediments and the trend of reefs on its flank. Current investigations indicate that in Paleozoic times the Hudson and Moose River systems were connected with those of the great lakes area to the south. The sediment rocks range in age from Ordovician at their western limit to Jurassic in the center of the basin. The basin consists predominantly of limestone and dolostone with

12 | P a g e

Assessment Report 2014 CLM 436, 109496 De Beers – Mining Canada

intercalations of shale, siltstone and sandstone. The sedimentary sequence in the area of interest indicates that the surface is underlain by four sedimentary sequences of Lower Silurian Formations overlying an Upper Ordovician sequence, which rests on basement rocks. The sedimentary rock package of the Attawapiskat area is approximately 250 m thick (Winzar, 2001). The uppermost limestone sediments are Silurian reef and bioherm deposits of the Attawapiskat Formation that have been severely faulted and uplifted in the immediate area of the Attawapiskat kimberlites. The major tectonic structure in proximity to the study area is the Winisk River Fault system which is clearly visible on the Canadian Geological Survey map of regional airborne magnetic data. Minor faults striking northwest-southeast and northeast-southwest transect the Attawapiskat area. Two sets of dykes are also visible on the magnetic data; dykes that strike northwest to southeast and the Matchewan/Hearst dykes that trend north-south (Winzar, 2001) (Kong, 1990).

The competent Precambrian bedrock is covered by frost heaved brecciated carbonate units overlain by thin Pleistocene till sheets and finally by thin marine and coastal Holocene deposits. Till and coastal Holocene deposits overlying the Attawapiskat kimberlites vary in thickness from 0 to 60 m.

3.0 ECONOMIC GEOLOGY

3.1 Previous Investigations Undertaken in the Tango Extension Kimberlite Bodies 4

Tango Extension kimberlite was discovered through BQ core drilling in 1988, and then mini-bulk sampled for MaDA in the winter of 2001. The results from the 2001 program helped identify Tango Extension as a potentially economic resource. Tango Extension The Tango Extension (TE) kimberlite lies approximately 7 km NNW of the Victor pit. Core drilling campaigns in 2002 and 2003, and an LDD program in 2003 followed the positive results obtained in the 2001 mini-bulk sample and began to properly

delineate the body. A heli-portable LF-70 drill rig was utilized for the 2002 and 2003 core drilling, while the LDD drilling was completed using a Foremost CT550 rig that drilled three 24” diameter holes. A total of 193,650 kg of wet material (504.44 m of kimberlite) was shipped to Grande Prairie for processing, returning a grade of 18 cpht. The TE pipe model featuring the kimberlite’s internal geology was created after this drilling, and was later updated in 2009 by re-logging of existing 2003 cores. In 2010, another drill program consisting of four LDD holes (not including one LDD hole that was abandoned) and 18 HQ core holes was completed, adding further confidence to the kimberlite’s model and grade. The 18 core holes were drilled in clusters of 2, 3 or 4 in and around the body. Each cluster was planned with a vertical hole and 1, 2 or 3 angled holes drilled away from the center of the kimberlite pipe for modeling purposes. This core drilling was conducted with two Zinex A5 drill machines, designated A5-1 and A5-2, and it was during this program that the Tango Extension Deep structure was first encountered in hole TE-10-055C. Unfortunately, the hole intersected a large floating reef and was unable to prove the existence of undiluted kimberlite at depth, therefore generating the need for the VicREP 2013 program at Tango Extension Deep.

Tango Extension is currently undergoing a conceptual phase of engineering design in order to determine whether or not the body can economically produce material that will add to Victor’s life of mine.

3.2 Geology of the Tango Extension Kimberlite

The Tango Extension pipe has a surface area of approximately 7 ha, while the Tango Extension Deep structure’s gravity anomaly indicates a surface size of 17 hectares. Tango Extension is an amoeboid-shaped body showing no obvious trend, and the Tango Extension Deep structure is a NE-SW trending oval. The body outline was postulated from the interpretation of Geophysical surveys which cover Tango Extension.

4.0 INVESTIGATIONS5 4.1 Ground Preparation

Prior to drilling, Ausenco Sandwell was requested by De Beers to determine the required frozen ground thickness to support the drilling equipment transport and positioning. The assessment resulted in the following recommendations6:

Required frozen ground thickness for initial roadway opening using a CAT D5 (20,434 lbs.) is 14” (36cm);

Required frozen ground thickness for mobilizing the drill rig (72,000 lbs.) is 20 inches;

Required frozen ground thickness for the drill sites is 31” and 35” when using top drive and bottom drive pullback, respectively.

Once the recommended ice thickness was known, MKS Construction was contracted for actual ground works i.e. frost thickening and access pad preparation.

4.2 Hydrogeology7

The main component of the program was the spinner log testing of two drillholes north (TE-3) and south (TE-4) of Tango Extension kimberlite as well as completion of a pilot hole to the east (TE-P) of the kimberlite for a future large diameter pump test well or permanent pump installation. In a broader perspective, this drilling will provide additional information in the development of a new regional groundwater flow model for the Victor Mine Extension Project. An illustration of the spinner log is shown below:

The hydrogeology drilling was commissioned to LBM of Victoriaville, QC employing a Foremost Dual Rotary Drilling Rig (DR-24HD). Drilling began in March 16 with downhole geophysical surveys being undertaken in conjunction with drilling until the permits for water taking and discharge were received allowing the spinner log testing (and associated pumping) to proceed. Permits to take and discharge water were issued on March 14, 2014.

The drilling sequence started with TE-14-060C, then TE-14-061C and finally, TE-14-062C. Shorter, one day pumping tests were run at each well after geophysical logging to obtain transmissivity values. The drillhole depths and construction of the piezometers (standpipe and Solinst transducers at TE-14-060C and grouted-in multilevel vibrating wire transducers at TE-14-061C) were defined. As the preliminary stratigraphic information from TE-14-060C suggested the blue green claystone at Tango Extension to be +/-20m shallower than at Victor, some adjustments were made to the planned drill depths (e.g. TE-14-062C was drilled to 175m vs 200m so as to avoid penetration of the lower, pressurized Severn River aquifer). The planned layout for the three (3) wells is illustrated below:

The hydrogeology program concluded with a three day pump test in early April. The last downhole survey was concluded on April 10, by which time all survey, geophysical and downhole transducer data had been passed to the Hydrological consultant (Itasca) for review and interpretation.

4.3 Core Drilling (Delineation)8 Two delineation core holes were planned, one in the west and another in the northeast to better constrain the shallow kimberlite contacts within Tango Extension. One additional vertical core hole was planned in the center of the pipe to determine overburden thickness and to provide samples for geotechnical characterization of the material.

Figure 12. Outline of Tango Extension Kimberlite with Location of Core Holes Planned

Note: UTM Projection & Datum NAD83 Canada Mean, Zone 17N.

There was a plan to drill a deeper geotechnical core hole to the SW of Tango Extension, but due to the slower than expected startup to the core drilling program, which was in part due to water supply pump delays, the originally planned deeper geotechnical hole could no longer be completed within the original budget and was not executed.

Core drilling was manned by Foraco Drilling Company using De Beers’ owned A5-2 drill rig. Drilling started on the western delineation core hole TE-14-63C on March 16, 2014 on a double shift basis. The trench overburden geotechnical hole was drilled between March 21-25 on a single shift basis as a Geotechnical Engineer from Golder Associates had been brought to site to supervise the overburden drilling, Shelby Tube sampling, and Shear Vane testing. The northeasterly delineation hole TE-14-65C was completed from March 25-29.

As part of the hydrogeological characterization at Victor Mine, borehole logging consisting of the following was conducted in TE-14-061C, TE-14-060C and TE-14-062C:

Caliper logs to assess borehole diameter and the locations of fractured zones in the bores;

Groundwater production (spinner) logs to assess the locations of groundwater inflow zones;

Groundwater electrical conductivity logs to assess groundwater characteristics in the various geologic formations penetrated by the bores; and

Natural gamma logs to locate stratigraphic marker horizons including overburden, the blue-green claystone, and the Attawapiskat–Ekwan River Formation contact.

Correspondingly, Itasca made the following interpretations based on the information collected: Characteristics identifiable on the three boreholes based on caliper logs are increased fracturing (or possibly solution cavity development) to a depth of at least 50 mbgs. This zone extends to approximately to 60mbgs in TE-14-060C and TE-14-061C and corresponds to the Upper Attawapiskat Unit. Fracturing is also observed in all three bores from approximately 120 to 130 mbgs, which corresponds to the Attawapiskat–Ekwan River Formation contact. The natural gamma logs are very similar for all three boreholes and clearly delineate geologic formation contacts. The logs indicate that the overburden extends to variable

depths of approximately 30 mbgs at TE-14-061C, 20 mbgs at TE-14-060C, and 13 mbgs at TE-14-062C. The Upper Attawapiskat Unit extends from the bottom of the overburden to the top of the blue-green claystone at depths of approximately 45 to 50 mbgs. The Lower Attawapiskat Unit extends to the top of the Ekwan River Formation, which is clearly marked by gamma spikes at depths of approximately 125, 120, and 130 mbgs for TE-14-061C, TE-14-060C and TE-14-062C, respectively. This formation stratigraphy is exactly analogous to the stratigraphy at Victor Mine—which has similar overburden thicknesses, depth to the blue-green claystone, and depth to the Ekwan River Formation. The production logs were obtained by lowering the so-called “spinner” tool through the water column in the bore while pumping groundwater from the bore at a rate of 350 U.S. gallons per minute (gpm). An electrical submersible pump was set inside the surface casing at the top of each bore and the spinner tool was lowered at a constant rate from a depth just below the pump intake to the bottom of the bore. The production log indicates where groundwater production is occurring, as a percentage of total production over the length of the bore. The production log for TE-14-061C shows slightly increasing production up through the Ekwan River Formation, but this formation only accounts for approximately 18% of total flow. In the upper and Lower Attawapiskat Unit, production zones occur from 100 to 120 mbgs and from 65 to 40 mbgs. The Attawapiskat Formation produces approximately 82% of the flow in this bore. The production log for TE-14-060C shows very little production from the Ekwan River Formation, which accounts for less than 10% of borehole inflow. Production increases throughout the lower and Upper Attawapiskat Unit with marked increases in flow at 93 mbgs and between approximately 30 and 53 mbgs. The production log for TE-14-062C could only be run to a depth of 125 mbgs because of an obstruction in the borehole. The log shows steadily increasing production up through the Lower Attawapiskat Unit with an abrupt increase at 93 mbgs and another at approximately 63 mbgs from an interval located just below the blue-green claystone. Production is limited from approximately 40 to 61 mbgs but steadily increases between 40 and 20 mbgs. The logs for boreholes TE-14-061C and TE-14-060C are similar in form, showing conductivity increases at depths of about 110 to 120 mbgs. These depths correspond to the contact of the Lower Attawapiskat Unit with the Ekwan River Formation and indicate that higher conductivity groundwater is present in the Ekwan River Formation. The log for TE-14-062C does not indicate a conductivity increase at the lower Attawapiskat–Ekwan River contact as observed at TE-14-061C and TE-14-060C. As indicated by the associated natural gamma log, it does show conductivity increases associated with the interbedded fine-grained strata of the Ekwan River Formation. With the additional observations noted above and previous studies, a draft regional groundwater flow model for the Victor Mine Extension Project was generated.

Overburden drilling in TE-14-064C was conducted by advancing HW casing and obtaining Shelby tube samples coupled with in-situ vane testing performed approximately 1m intervals for the first 10m and 2.5m intervals thereafter through the clay / till until bedrock was encountered, to delineate the overburden bedrock contact. Approximately 10.5m of HQ core was obtained to characterize the upper kimberlite zone prior to borehole completion. Total depth of the drilling was 31.1m, consisting of 19.7m of overburden and 10.5m of bedrock. It should be noted that the borehole was located overtop a small frozen pond with a depth of about 0.9m. The bedrock encountered is kimberlite which appears to be slightly-moderately to highly weathered towards the end of hole. Total Core Recovery ranged from 27-100% with an average of 73%. The Solid Core Recovery is from 0-65%, average 28% while RQD range from 0-75% and 32% average. Six (6) overburden samples were submitted to laboratory for testing of the following: moisture content, grain size distribution, Atterberg limits, specific gravity and consolidated undrained triaxial testing. Sampling results have led the Geotechnical consultants to come up with recommendations regarding future overburden slope design and excavation considerations.10 For the two holes drilled in pipe margins, TE-14-063C intersected kimberlite from 37 to 86m while TE-14-065C crossed kimberlite from 28.5 to 105m. Both characterize a weathered kimberlite near surface and brecciated kimberlite at depth. Kimberlite intersections for the three holes are listed in Table 7. A section of the holes in plan view is shown in Figure 13.

6.0 CONCLUSION

The 2014 hydrogeology and delineation program was completed as per the scope of work.

The three hole spinner logging test was accomplished from two additional monitoring wells and a production well in the vicinity of the Tango Extension kimberlite body. The additional information obtained from this test and previous studies resulted in the development of a new regional groundwater flow model for the Victor Mine Extension Project (draft).

The Tango Extension kimberlite shallow contacts have been identified based on the kimberlite intersections drilled. The depth of overburden at the center of Tango Extension kimberlite is 19.7m (18.8m corrected for ice depth). Overburden samples tested for geotechnical characterization resulted in the recommendation of best slope/bench configurations to the proposed Tango Extension trench/pit. 7.0 PERSONNEL A RACI (Responsible, Accountable, Consulted, Informed) Matrix is attached (Appendix 3) to list all the personnel and external contractors involved in the 2014 drilling program. A contract Geologist was hired by De Beers to conduct core logging, core shipment and data entry. The program also have utilized personnel from various departments of Victor mine for logistical assistance and support.
