EXECUTIVE SUMMARY
Minxcon (Pty) Ltd (“Minxcon”) was commissioned by Xtract Resources PLC (“Xtract”, “the Company” or
“the Client”) to complete an Independent Technical Report (or the “Report”) on the Mineral Resources
of the Fair Bride Prospect, (“Fair Bride”) on the 3990C Mining Concession of the Manica Gold Project,
(“Manica” or “Project”), situated in the Odzi-Mutare-Manica Greenstone Belt of Mozambique and
Zimbabwe. This document is intended as a Mineral Resource estimation update of the Fair Bride
Prospect within the greater Manica Project. The Report has an effective date of 4 March 2016.
The Mineral Resources are considered by the Competent Person to be fully compliant with the South
African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (2008
Edition, as amended 2009) (“the SAMREC Code”) and the South African Code for the Reporting of Mineral
Asset Valuation (2008) (“the SAMVAL Code”) and Section 12 of the Johannesburg Stock Exchange listing
requirements. The Competent Person of the Report deems this summary a true reflection of the content
of the full Technical Report.
The Fair Bride Prospect, located on the 3990C Mining Concession of the Manica Gold Project, was visited
by the Competent Person, Mr Uwe Engelmann, from the 15th of March 2016 to the 17 th of March 2016.
The total area of the Mining Concession 3990C is approximately 42 km2 and the area of focus in the Fair
Bride prospect covers an area of approximately 1.53 km2. The Mining Concession 3990C is located
approximately 4 km north of the city of Manica and 52 km southwest of the city of Honde in the Manica
Province of Mozambique.
Manica is a historical gold mining area with prehistoric mining and exploration activities. Known
historical exploration activities on the Fair Bride prospect have taken place since 1964. The Brigada de
Formento Mineiro (“BFM”) first explored the area in 1964 where they conducted geological mapping of
the project area. They were followed by Lonrho in 1987, and then by Explorator Limitada who were
sponsored by Pangea.
From 2001 to 2011, Pan African Resources (“PAF”) conducted extensive exploration activities followed
by Auroch Minerals who subsequently drilling additional drillholes from 2013 to 2015, prior to the
acquisition of the property by Xtract.
The Project Area is located within the 2.6-2.7 Ga Odzi-Mutare-Manica (“OMM”) Greenstone Belt which
occurs on the eastern side of the Zimbabwe Craton, which formed the northern portion of the larger
Kalahari Craton. The OMM Greenstone Belt is predominately composed of a strong east-west trend and
locally folded ultramafic/mafic volcanics and serpentinites alongside metasediments. Tonalite
trondjhemite granodiorite (TTG) granite gneisses of the Vumba Granite Gneisses form a boundary to the
OMM Greenstone Belt to the north and south. The Messica Granite Gneisses truncate the eastern margin
of OMM Greenstone Belt and are the predominant unit making up the Kalahari Craton in the area. Slight
changes in the regional trend are thought to suggest a sinistral sense of shear along the northern craton
margin (Grieve, 2015). Beyond and including the western fraction of the Messica Granite Gneiss, the
dominant trend in the Mozambique Metamorphic Belt becomes dominantly north-south (Manhica et. al.,
2001). The contact where the Kalahari Craton terminates against the Mozambique Metamorphic Belt in
the east is a result of the Grenville Orogeny that formed the first supercontinent, Rodinia (1,000-1,200
Ma). Gneisses, migmatites, granitoids with mafic, quartzite, marble and calc-silicate intercalations are

Province, Mozambique v
the main constituent of the Mozambique Metamorphic Belt which is interpreted to have formed from a
turbidite sequence. North-south orientated mafic dykes occur in both the Kalahari Craton and
Mozambique Metamorphic Belt and are increasingly metamorphosed towards the craton boundary
(Grieve, 2015).
The eastern extension of the OMM Greenstone Belt is known as the Manica Greenstone Belt. There is a
change in the general strike of the greenstone belt which is likely to be representative of shearing,
evidence for which is found along the greenstone margins constrained by the Vumba Granite Gneisses
(Manhica et. al., 2001). This regional shear is considered to be related to the crustal scale east-
northeast to northeast trending Mutare-Masvingo-Sandawana (“MMS”) Shear Zone (Stepcich and Naidoo,
2012).
The Macequece Formation (in which the Fair Bride orebody occurs) and Vengo Formations are the most
important lithologies within the Manica area of the greenstone belt. Ultramafic/mafic metavolcanics
with intercalations of banded iron formation (“BIFs”), serpentinite and metachert are the main
constituent of the lowermost Macequece Formation. These rocks have been significantly altered by the
regional retrograde metamorphism becoming rich in talc, chlorite amphibole and tremolite. The Vengo
Formation which is interpreted to be a younger, shallow water sedimentary unit comprised of
metamorphosed shales, dolomitic limestones, siliceous volcanics, and quartzites, lies unconformably
over the Macequece Formation. The grade of metamorphism in the Odzi-Mutare-Manica Greenstone Belt
ranges from lower amphibolite facies to lower greenschist facies in the east around Manica and has
significantly altered these rocks.
There are three east-west trending synforms that have been identified, plunging 20°to 25° to the east
within the major OMM Greenstone Belt synform. Tight isoclinal antiforms, in some places, have been
truncated by thrust faults separated the synforms. Deformation is principally associated with the
Mutare-Masvingo-Sandawana (“MMS”) strike slip shear zone that extends 500 km from Eastern
Mozambique to Southern Zimbabwe (Grieve, 2015). Large (> 10 km) regional east-northeast structures
that vary in trend locally have been formed as a result of shearing.
Two adjacent regional shears which hosted the gold mineralisation within the Fair Bride project area are
located on the margins of one of the OMM Greenstone Belt synforms. The Fair Bride project is located on
the southern flanks of the syncline and strikes east-west.
The Project Area is situated on the southern part of the Mining Concession 3990C alongside a 7 km
extension of the BIF horizon.
Exploration activities conducted on Fair Bride suggested that gold occurrence or mineralisation is closely
associated with arsenopyrite and has been primarily intersected within the sedimentary units, BIF,
greywackes and phyllites. Gold mineralisation is usually controlled by quartz sulphide veins which occurs
as lenses along the shear zone.
Mineralisation is oxidised to a depth of about 50 m to 60 m below the surface. Minerals such as
magnetite, hematite, limonite, hornblende, carbonate, sericite, albite and auriferous pyrite,
arsenopyrite and pyrrhotite as well as native gold are the main constituent of the host rocks. The host
rocks lithologies contain orebodies which vary in thickness from 2 m to 30 m, are sub-vertical and with
strike lengths of several hundred metres.
A geological model of the Fair Bride orebody was constructed using the geological interpretation,
supplied by Xtract in the form of geological sections. These sections were used to create a wireframe for

Province, Mozambique vi
the orebody or mineralised portion. The sections represent a geological interpretation based on the
lithology and mineralisation which was correlated with physical characteristics in the core. The main
mineralisation occurs predominantly in the metasediments (BIF) and rhyolites. This lithological /
geological model was also tested against a grade shell halo which provided a good correlation. The
wireframe surfaces were also divided into an oxide, transition and sulphide zone based on the
weathering limits.
Historical exploration included surface mapping, soil geochemical surveys, trenching, magnetic and
induced polarity (“IP”) surveys. These all contributed to the target generation for the exploration
drilling. This drilling included diamond drilling and reverse circulation (“RC”) drilling.
A total of 113 RC drillholes totalling 9,265.97 m were completed on the Fair Bride prospect. RC drillholes
were drilled using a 120 mm bit using a face sampling hammer.
116 diamond drillholes, totalling 22,396.82 m, were completed on the Fair Bride prospect. All diamond
drillholes drilled prior to 2013 were drilled using HQ sized bits (63.50 mm) within the weathered zone
while the NQ sized bits (47.60 mm) were used to drill in more competent material (fresh rock). Those
drillholes drilled in 2012 and 2013 were drilled using PQ (85 mm) sized bits before casing off to HQ sized
bits.
During the various drilling campaigns, quality assurance and quality control (“QA/QC”) measures were
implemented, resulting in a reliable database. The database utilised for the Mineral Resource estimation
was deemed to be reliable and represent the geology of the Project which was confirmed during the site
inspection in March 2016.
94 diamond drillholes and 43 RC holes were utilised in the Mineral Resource estimation. Ordinary kriging
was used for the estimation methodology. Only samples falling within the ore boundary wireframe were
used for the estimation, and a capping regime was used where sample values exceeding 20 g/t over a 1
m composite were capped at 20 g/t (99th percentile). Soft boundaries were included to estimate the
oxide zone where data points were included from the transitional zone to inform the oxide zone. A
variogram range of 198 m in the long range and 149 m in the short range was used. The variogram was
also constrained in the Y range to 11 m to prevent overestimation across the width of the mineralised
zone. The final block estimate utilises a 5 m X 5 m X 5 m block size with sub cell splitting.
The Mineral Resource was classified into Measured, Indicated and Inferred categories as defined in the
SAMREC Code based on the kriging efficiency, number of samples and search radii.
The resultant Mineral Resource estimation, for the open pit and underground, for Fair Bride is shown in
the two tables below.

Conclusions
The database is a reliable database for Mineral Resource Estimation;
After discussions with the project geologist, no fault was interpreted between the eastern and
western portions of the main (higher grade) Fair Bride orebody – this area potentially requires
further investigation;
Downhole surveys were not conducted on all the holes and this might influence the local
accuracy of the mineralised zone, as the two long holes ANDD039 and ANDD037 show significant
deviation;
The mineralised strike of the ore body is approximately 1,040 m;
Open pit resource has been declared to a depth of 280 m (which is the average depth of the two
modelled pits) – resource cut-off of 0.5 g/t;
The open pit is predominantly Measured and Indicated Mineral Resource;
The depth extension (underground resource) is predominantly in the Inferred Mineral Resource
category and is to a depth of approximately 530 m;
Currently the densities utilised are based on the oxide, transition and sulphide zones. There is
no split in the densities on lithology type – especially the BIFs and rhyolites which comprise the
majority of the orebody;
The 2016 Mineral Resource has a grade similar to that of the 2010 Mineral Resource estimation
but is lower than the 2014 Mineral Resource estimation. This is due to the fact that the 2014
estimation utilised local uniform conditioning (“LUC”) and the 2010 and 2016 estimation utilised
ordinary kriging;
It is Minxcon’s opinion that the ordinary kriging will deliver a more realistic mining grade for
mine design purposes; and
The 2016 Mineral Resource estimation honours the geology / lithology of the Fair Bride orebody.
Recommendations
The underground Mineral Resource, which is predominantly in the inferred category, requires
infill drilling to improve the confidence levels;
The additional drilling for the depth extension should be surveyed down the hole as the previous
long holes show significant deviations;
Additional drilling is required at the western portion of the strike to investigate if the depth
extension is also low grade;
The difference in the densities of the lithologies should be investigated to assess the impact;
and
It is the authors’ opinion that the ordinary kriged model should be utilised for mine design as it
gives a more realistic mining grade model.

1.3 COMPETENT PERSONS’ PERSONAL INSPECTION OF THE PROPERTY
The Fair Bride Prospect, located on the 3990C Mining Concession of the Manica Gold Project, was
visited by the Mr Uwe Engelmann, the Competent Person of this Report, from the 15th of March
2016 to the 17th of March 2016. During this site visit the following was inspected:-
Infrastructure;
Location of the historical mining pits;
Surface geology in the pits; and
Drillhole core with associated logs.
The figure below shows one of the historical pits related to the Fair Bride prospect. These pits have
been delineated by a LIDAR survey and have been depleted from the Mineral Resource.

Figure 2 below shows the mineralised metasediments, banded iron formation (“BIF”), that comprise
the majority of the Fair Bride orebody. This is also illustrated in the Fair Bride sections (Figure 10)
in section 6 of the document.

Mineralised BIF in the Fair Bride Main Pit (Looking West) March 2016
Figure 3 below portrays a photo of a well mineralised intersection within the BIF in drillhole
ANDD093. This particular intersection had a high gold grade and was associated with the
arsenopyrite in a highly altered, deformed and silicified lithology. In general the more abundant
the quartz veining stock work is the higher the sulphide mineralisation and gold grades are. This
will help during the visual identification of the orebody during the mining operations. A second
lithology often associated with higher gold grades is the type 2, characterised by highly altered
chlorite schist or rhyolite which also exhibits high degrees of deformation, alteration with sulphides
(predominantly arsenopyrite) and quartz/carbonate veining.

3 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE
AND PHYSIOGRAPHY
3.1 ACCESSIBILITY
SAMREC T1.2 (i)
The Fair Bride prospect is accessible by dirt road from Manica city. Manica can be reached by tar
road from Johannesburg via Beitbridge, Mutare (approximately 1,239 km) or from Harare in
Zimbabwe via Mutare (approximately 409 km). Air services link major regional centres of
Johannesburg, Maputo, Harare and Chimoio (located 70 km from the Project Area).
3.2 CLIMATE
SAMREC T1.6 (i)
In general, the tropical climate of Mozambique is characterised by warm to hot and wet summer
and mild, dry winter seasons. An annual rainfall of 1,000 mm to 1,500 mm occurs during the rainy
season in summer (November to March). In summer, the maximum average temperature is around
23°C and in winter the temperature is approximately 7°C.
Minxcon is of the opinion that the climate will not affect exploration or future mining activities.
Rainfall may hinder access and transport at the site, as roads are currently gravel-clay.

4.2 HISTORICAL EXPLORATION AND DEVELOPMENT
Manica is an historical gold mining area. Prehistoric mining and exploration activities started during
the time of the Monomotapa Empire, after which it was continued by the Portuguese and other
Europeans from the 1800s to about the 1970s.
Documented historical exploration activities on the Fair Bride prospect took place since 1964. The
Brigada de Formento Mineiro (“BFM”) first explored the area in 1964 where they conducted
geological mapping of the Project Area. They were followed by Lonrho in 1987, and then by
Explorator Limitada who were sponsored by Pangea.
From 2001 to 2011, Pan African Resources (“PAF”) conducted extensive exploration activities which
included: detailed geological mapping of the project area, a magnetic field intensity (“TMI”) survey
and a gradient array induced polarisation (“IP”) survey, drilling of 79 RC drillholes and 100 diamond
drillholes. Auroch Minerals subsequently drilled 9 reverse circulation (“RC”) drillholes and 11
diamond drillholes from 2013 to 2015, prior to the acquisition of the property by Xtract. Table 2
below summarises historical exploration activities which were completed on the Fair Bride area.

4.3 HISTORICAL MINERAL RESOURCE ESTIMATES
In February 2006 and February 2008, an independent Mineral Resource specialist and director of
GeoLogix Mineral Resource Consultants (Pty) Ltd, Mr. Deon van der Heever, completed a Mineral
Resource estimation on the Project Area. Table 3 and Table 4 below summarise the Mineral
Resource estimation results completed by Mr van der Heever in 2006 and 2008, respectively. In
2010, ExplorMine Consultants was commissioned by PAF to complete an Independent Competent
Person Report and a Mineral Resource statement was declared as indicated in Table 5. In 2014,
Auroch Minerals (“Auroch”) geologist in collaboration with CSA Global declared Mineral Resource
statement as indicated in Table 6. The grade variation between the two estimations is due to the
estimation methodology. The 2010 Mineral Resource Estimation utilised ordinary kriging whereas
the Auroch estimate utilised local uniform conditioning (“LUC”) for the final estimation
methodology.

5 GEOLOGICAL SETTING AND MINERALISATION
SAMREC T1.2 (i)
5.1 REGIONAL GEOLOGY
SAMREC T4.1 (i)
The Project Area is located within the 2.6-2.7 Ga OMM Greenstone Belt which occurs on the eastern
side of the Zimbabwe Craton, and formed the northern portion of the larger Kalahari Craton. The
Vumba Granite Gneiss, the OMM Greenstone Belt, the Messica Granite Gneiss, the Frontier
Formation, the Tchinhadzandze Granodiorite Gneiss and mafic intrusives are the main lithological
groups of the Kalahari Craton.
The OMM Greenstone Belt is predominately composed of a strong east-west trend and locally folded
ultramafic/mafic volcanics and serpentinites alongside metasediments. Tonalite trondjhemite
granodiorite (TTG) granite gneisses of the Vumba Granite Gneisses forms a boundary to the OMM
Greenstone Belt to the north and south. The Messica Granite Gneisses truncate the eastern margin
of OMM Greenstone Belt and are the predominant unit making up the Kalahari Craton in the area.
The Messica Granite Gneisses become increasingly foliated towards this boundary (Manhica et. al.,
2001) and are characterized by leucocratic granite composed of biotite, muscovite and garnet
(Manhica et. al., 2001). Figure 6 below shows the regional geology.

An Independent Technical Report on the Mineral Resources of the Fair Bride Gold Deposit on the 3990C Mining Concession,
Manica Province, Mozambique 12
The Frontier Formation occurs as outliers within the Messica Granite Gneiss, found as tight north-
south orientated synclines composed of quartzites and mica schists, a characteristically different
trend to the dominant east-west trend of the OMM Greenstone Belt (Grieve, 2015). The OMM
Greenstone Belt is underlain by one outlier of the Frontier Formation and this suggest that the
outlier is tectonically emplaced under the overlying sequence. The east-west to east-northeast to
west-southwest strike with a north-south dipping plane, is the dominant trend encountered within
the OMM Greenstone Belt and Vumba Granite Gneisses. The trend becomes progressively east-
northeast to west-southwest further eastwards until truncation against the Messica Granite
Gneisses occurs. This is thought to suggest a sinistral sense of shear along the northern craton
margin (Grieve, 2015). The undeformed or foliated Messica Granite Gneisses suggests the fabric
developed in the OMM Greenstone Belt and that the Vumba Granite Gneisses preceded
emplacement of the Messica Granite Gneiss. Beyond and including the western fraction of the
Messica Granite Gneiss, the dominant trend in the Mozambique Metamorphic Belt and Frontier
Formation becomes dominantly north-south (Manhica et. al., 2001). The contact where the Kalahari
Craton terminates against the Mozambique Metamorphic Belt in the east is a result of the Grenville
Orogeny that formed the first supercontinent, Rodinia (1,000-1,200 Ma). The Mozambique
Metamorphic Belt is considered to have formed during the collision of the continents leading to an
accretion of sediments onto the eastern margin of the Kalahari Craton (Grieve, 2015).
Gneisses, migmatites, granitoids with mafic, quartzite, marble and calc-silicate intercalations are
the main constituent of the Mozambique Metamorphic Belt which is interpreted to have formed
from a turbidite sequence. North-south orientated mafic dykes occur in both the Kalahari Craton
and Mozambique Metamorphic Belt and are increasingly metamorphosed towards the craton
boundary (Grieve, 2015).
5.2 LOCAL AND PROPERTY GEOLOGY
The OMM Greenstone Belt extends 25 km eastwards into Mozambique and lies within the intact
Zimbabwe craton. The eastern extension of the OMM Greenstone Belt is known as the Manica
Greenstone Belt. The OMM Greenstone Belt extends approximately 115 km westwards, where the
dominant trend is east-northeast, arcing into an east-west trend through the Manica area before
swinging back east-northeast to west-southwest were it terminates against the Messica Granite
Gneisses (Koll, 2014; Lord et. al., 2012; Manhica et. al., 2001). The change in strike of the
greenstone belt is likely to be representative of shearing, evidence for which is found along the
greenstone margins constrained by the Vumba Granite Gneisses (Manhica et. al., 2001). This
regional shear is considered to be related to the crustal scale east-northeast to northeast trending
Mutare-Masvingo-Sandawana (“MMS”) Shear Zone (Stepcich and Naidoo, 2012).
The Macequece Formation (in which the Fair Bride orebody occurs) and Vengo Formations are the
most important lithologies within the Manica area of the greenstone belt. The Macequece and
Vengo Formations are known to correlate to the Upper Bulawayan and Shamvaian Supergroups in
the Central Zimbabwe Craton. Ultramafic/mafic metavolcanics with intercalations of BIF,
serpentinite and metachert are the main constituent of the lowermost Macequece Formation.
These rocks have been significantly altered by the regional retrograde metamorphism becoming
rich in talc, chlorite amphibole and tremolite. The Vengo Formation which is interpreted to be a
younger, shallow water sedimentary unit comprised of metamorphosed shales, dolomitic
limestones, siliceous volcanics, and quartzites, lies unconformably over the Macequece Formation.
The grade of metamorphism in the OMM Greenstone Belt ranges from lower amphibolite facies to
lower greenschist facies in the east around Manica and has significantly altered these rocks. Figure
7 below shows different lithologies within the OMM Greenstone Belt.

Figure 7: Lithology within the Odzi-Mutare-Manica Greenstone Belt
Lithology within the Odzi-Mutare-Manica Greenstone Belt March 2016
The OMM Greenstone Belt is a complex Archaean terrane that is largely classified as synformal. The
synform consists of mafic to ultramafic volcanics (Macequece Formation) on the margins of the
fold, with coarse clastic sediments (Vengo Formation) in the core of the fold (Grieve, 2015). There
are three other east-west trending synforms that have been identified, plunging 20°to 25° to the
east within the major synform. Tight isoclinal antiforms, in some places, have been truncated by
thrust faults separated the synforms. Deformation is principally associated with the MMS strike slip
shear zone that extends 500 km from Eastern Mozambique to Southern Zimbabwe (Grieve, 2015).
Large (>10 km) regional east-northeast structures that vary in trend locally have been formed as a
result of shearing.
Late post-kinematic north-northeast to north-south brittle-ductile faults that have displaced
laterally trending units have cut and offset the east-west folded trend of the OMM Greenstone Belt.
These faults are believed to have played an important role in the formation of the late diabase (ca.
1820 Ma) and dolerite dykes (ca. 800-570 Ma) which cut across both the OMM Greenstone Belt and
the surrounding units (Grieve, 2015).

5.3 MINERALISATION
SAMREC T1.4 (i)
Two adjacent regional shears which hosted the gold mineralisation within the Fair Bride Project
Area are located on the margins of one of the OMM Greenstone Belt synforms. The Fair Bride
Project is located on the southern flanks of the syncline and strikes east-west.
The Project Area is situated on the southern part of the 3990C Mining Concession alongside a 7 km
extension of the BIF horizon on which the Rezende Mine is situated in Zimbabwe. The BIF horizon
with a strike length of approximately 7 km extends from the old mine at Dot’s Luck Project to the
centre of Fair Bride. Gravels and alluvium covers most of the ground.
Historical and current exploration activities conducted on Fair Bride Project which includes surface
geological mapping, geochemical and geophysical survey, RC and diamond drilling suggested that
gold occurrence or mineralisation is closely associated with arsenopyrite and has been primarily
intersected within the sedimentary units, BIF, greywackes and phyllites. Gold mineralisation is
usually controlled by quartz sulphide veins which occurs as lenses along the shear zone. These
lenses have been observed to be associated with structural jogs or inflections within the shear zone
(ExplorMine, 2008). Figure 9 shows the project geology.

Mineralisation is oxidised to a depth of about 50 m to 60 m below the surface. Minerals such as
magnetite, hematite, limonite, hornblende, carbonate, sericite, albite and auriferous pyrite,
arsenopyrite and pyrrhotite as well as native gold are the main constituent of the host rocks. The
host rocks lithologies contain orebodies which vary in thickness from 2 m to 30 m, are sub-vertical
and with strike lengths of several hundred metres.

6 DEPOSIT TYPES
6.1 MINERAL DEPOSITS BEING INVESTIGATED
SAMREC T1.2 (i)
The Fair Bride deposit is an Archean Greenstone Belt Orogenic Gold deposit. The deposit occurs in
the eastern part of the 2.6-2.7 Ga OMM Greenstone Belt and is hosted within the sedimentary units
that have been metamorphosed to upper greenschist to lower amphibolite facies to form a
metamorphosed sequence of low-MgO ultramafic to mafic rocks. The orebody occurs along a shear
zone which strikes east-west and is steeply dipping at approximately 75°. Mineralisation occurs in a
retrograde multiply-deformed vein stock work within a surrounding alteration halo. The gold
mineralisation is believed to be associated with syn- to post-kinematic arsenopyrite (up to 5%)
within a silica + chlorite + albite + biotite + Illite ± carbonate ± pyrite + alteration halo.
6.2 GEOLOGICAL MODEL
SAMREC T2.1 (i), T4.1 (I, ii, iii), T4.2 (iv, v)
Data obtained from geological surface mapping, trenching, RC drilling and diamond drilling were
used to generate the 3D geological model of the Fair Bride prospect area.
A geological model of the Fair Bride orebody was constructed using the geological interpretation,
supplied by Xtract in the form of geological sections (Figure 10). These sections were a result of
sections created in Surpac (by the project geologist) which were then remodelled in Datamine
Studio™ (by Minxcon and the Xtract geologists). The sections represent a geological interpretation
based on the lithology, which was correlated by the onsite geologist using core drilling data.
The main mineralisation occurs within the rhyolite (brown crosses) and metasediments (purple
dashed lines, Figure 10). These units were used for the geological model (Figure 11). This
lithological/geological model was also tested against a grade shell halo by Minxcon (using Leapfrog
Geo™ software) and a good correlation was found. The resultant geological wireframe model was
reviewed by the resident Xtract geologist. Upon review, the geological wireframe model (Figure 12)
was utilised as a physical constraint or orebody limit during Mineral Resource estimation. The
wireframe surfaces for the base of oxide and top of the sulphide zones were created from the point
data from the log files, where weathering was recorded and were utilised in defining these
geological weathering limits in resultant Mineral Resource block model.

7 EXPLORATION
SAMREC T2.3 (i)
7.1 SURVEY PROCEDURES AND PARAMETERS
SAMREC T2.2 (i)
Drillhole collar positions were surveyed by a qualified surveyor. Downhole surveys were carried out
on 14 diamond drillholes. All drillholes drilled post 2011 were surveyed by a qualified surveyor using
a DGPS to centimetre accuracy. Collar positions of drillholes were randomly checked in the field by
a geologist using a global positioning system (“GPS”), and historical drillholes were re-surveyed by a
qualified surveyor to warrant centimetre accuracy in 2007. Prior to 2007 no downhole surveys were
completed, and post 2007 downhole survey was carried out by the Geosearch South Africa (Pty) Ltd
on drillholes ANDD037 and ANDD039 using Reflex gyro downhole tool and all those drilled since June
2013 were surveyed by WeatherfordWireline Services, Tete, using a downhole gyro.
7.2 SAMPLING METHODS AND SAMPLE QUALITY
7.2.1 Gold in Soil Geochemical Survey
In 2001, bulk leach extractable gold in soil geochemical survey was completed on the southern
portion of Mining Concession 3990C by Explorator Limitada. This survey covered an area of 9.9 km
by 1.5 km. The survey was completed using a 50 m X 100 m soil sampling grid.
7.2.2 Arsenic in Soil Geochemical Survey
In 2003 to 2004, an initial orientation arsenic (As)-in-soil geochemical survey was conducted in the
vicinity of the Fair Bride workings to ascertain the validity of the method. Soil samples were
collected from a depth of 40 cm on a 10 m X 50 m grid along a limited strike length and along lines
of 350 m.
7.2.3 Trenching
A total of twelve trenches totalling 3,357.50 m were dug to a 5 m depth and samples were
collected as continuous 1 m channel samples from between 4 m and 5 m depths (Table 7). The
table below summarises the trenching that was completed on the Fair Bride prospect area.

7.3 SAMPLE DATA
7.3.1 Gold in Soil Geochemical Survey
The 500 g samples were analysed by a bottle-roll in cyanide solution with an atomic absorption
spectrometer (“AAS”) finish with a 3 ppb detection limit. The laboratory that analysed the samples
is unknown to Minxcon.
7.3.2 Arsenic in Soil Geochemical Survey
Samples collected were prepared and sent for analyses to Antech Laboratories in Kwekwe,
Zimbabwe (SANAS accredited laboratory No. T0194). The sample analysis was carried out by total
mixed acid digestion of 5 g and finished using an AAS finish. The method was shown to be valid and
the survey area was extended for 1.2 km east of Fair Bride. A 20 m X 100 m grid was used along 840
m lines.
7.3.3 Trenching
The strategy used for compositing and assaying trench samples was adopted from RC sampling,
however the gold grade assays for trench samples were generally lower than the RC chip samples
and diamond drill core samples. It was concluded that the lower gold grade assay might have been
due to shallow dispersion processes in the supergene. It was decided to exclude the trench assay
data due to mixing of samples and poor performance to the certified reference material (“CRM”)
and other reference material.
7.4 RESULTS AND INTERPRETATION OF EXPLORATION INFORMATION

Soil Geochemical Surveys
Figure 17 and Figure 18 below show gold and arsenic in soil geochemical surveys carried out in 2001
and 2003 – 2004 respectively. Note that the data collected from the area underlain by the alluvium
is not to be taken into account as it does not reflect the Archean substrate with the target
lithologies. Both element surveys are to some extent efficacious in representing the southern (and
upslope) limit of the deposit.

8 DRILLING
SAMREC T2.3 (i)
8.1 TYPE AND EXTENT OF DRILLING
A total of 113 RC drillholes totalling 9,265.97 m were completed on the Fair Bride prospect. RC
drillholes were drilled using a 120 mm bit using a face sampling hammer.
A total of 116 diamond drillholes totalling some 22,396.82 m was completed on the Fair Bride
prospect. All diamond drillholes drilled prior to 2013 were drilled using HQ sized bits (63.50 mm)
within the weathered zone while the NQ sized bits (47.60 mm) were used to drill in more
competent material (fresh rock). Those drillholes drilled in 2012 and 2013 were drilled using PQ (85
mm) sized bits before casing off to HQ sized bits.
8.2 FACTORS INFLUENCING THE ACCURACY OF RESULTS
SAMREC T3.2 (iii)
The Fair Bride orebody shear zone strikes east-west and is dipping approximately 75°. All drillholes
were inclined with a -50° to -60°dip and oriented in a north-south direction so as to minimise any
bias between drilling orientation and mineralisation structure. All the intersections are reported as
apparent (downhole) widths.
Sample recoveries for both RC chip samples and diamond drill samples were recorded. RC chip
sample recoveries were measured by weighing each 1 m sample and recording the sample mass
recovered. Scatter plots of assay gold grade vs recorded sample per metre and histograms of the
recorded sample per metre mass did not indicate any systematic bias of these data sets.
Standard logging techniques were used for recording diamond drill core recoveries where the
recovered core was measured and compared to the depth block inserted by the drilling contractor
during drilling. Diamond drill core recoveries were reasonably good with a mean of 88 % and a
median of 99 %.
8.3 EXPLORATION PROPERTIES – DRILLHOLE DETAILS
Table 8 and Table 9 below summarise RC and diamond drilling that was undertaken on the Project
Area. Drillholes ANDGT1 to ANDGT6 are geotechnical holes and MDD001 to MDD007 are

9 SAMPLE PREPARATION, ANALYSES AND SECURITY
9.1 SAMPLE HANDLING PRIOR TO DISPATCH
SAMREC T3.2 (I, v)
A qualified geologist logged both RC and diamond drillholes at the time of drilling. In 2014, Auroch
Minerals’ geologist re-logged previous diamond drillholes to standardise historical codes and
verification of weathering or oxidation boundaries.
Sampling of diamond drill core was conducted at 1 m intervals, but was constrained by the
geological contacts. The diamond drill core was not orientated during drilling, however the centre
line was drawn using the foliation plane for reference. Drill core was sawn and then split into two
halves, of which one was then marked, sampled and dispatched to a variety of accredited
laboratories by a qualified geologist. The remaining split half core was stored in a standard core
tray onsite in a covered core shed.
RC samples were collected at 1 m intervals. The samples were weighed and a rifle splitter was used
to split samples down to 6 kg. 200 g sub-samples were then scooped from each 6 kg sample and
used to make up a 3 m composite sample. The remaining 5.8 kg of the 6 kg sample was stored in a
secure core yard at Cacarue. The 3 m composites samples were assayed. Samples were sent to
variety of accredited laboratories.
9.2 SAMPLE PREPARATION AND ANALYSIS PROCEDURES
SAMREC T3.3, T3.4
This section was adopted from the 2010 Independent Competent Persons Report for the Manica
Assets, of Pan African Resources PLC which was compiled by ExplorMine Consultants. No current
sampling was available to assess the preparation or analysis procedures at the time of the
generation of this Report.
Prior to 2006, the site geologist personally transported each batch of samples from Manica to
Mutare in Zimbabwe for analysis by Antech Laboratories. Any sample packets opened for inspection
by customs officials were re-sealed by the site geologist. After inspection by customs, all sample
packets were sealed in polyweave sacks and delivered to Swift Transport (in Mutare) for shipment
to Antech Laboratories in Kwekwe, Zimbabwe.
The Antech Laboratory did not report any damaged consignments. It was considered by ExplorMine
Consultants that the chain of custody was adequate.
Antech Laboratory in Kwekwe, Zimbabwe, which was SANAS accredited (testing laboratory No.
T0194) at the time of the Manica exploration-drilling programmes carried out all sample analyses
prior 2006. Each sample was dried, crushed and pulverised. A quartz wash was used to clean
equipment between individual samples. A 50 g aliquot was taken for analysis. Gold analysis was
conducted by means of fusion of the 50 g aliquot, followed by AAS determination to a detection
limit of 0.01 ppm.
A rigorous quality assurance and quality control (“QA/QC”) system was put in place whereby every
tenth sample submitted to the laboratory consisted of a standard, blank or a duplicate control
sample.
All pulps were retained at the Antech laboratory, however Minxcon is not aware of how long the
pulps were retained at the laboratory. Duplicate sample pulps were also submitted to Genalysis
Xtract Resources PLC
An Independent Technical Report on the Mineral Resources of the Fair Bride Gold Deposit on the 3990C Mining Concession,
Manica Province, Mozambique 32
Laboratories (Accredited by the National Association of Testing Authorities, Australia, of Perth,
Australia for comparative purposes).
From 2006 to 2008 samples were submitted to SGS Lakefield’s Johannesburg-based analytical
laboratory or on some occasions to SGS Lakefield’s Barberton laboratory for analysis. The SGS
Lakefield laboratories are SANAS accredited (testing laboratory No. T0169). Analysis was by fire
assay with fusion of a 50 g aliquot followed by AAS to a limit of 0.01 ppm. This was a total assay.
In terms of the sample preparation for geological samples, at SGS’s laboratories, the following
sample preparation procedure was followed:-
Samples were removed from the shipping container or plastic bags. Samples were dried
overnight at 110°C as required.
The entire sample was passed through a jaw crusher. The jaw crusher product was
randomly monitored by means of sieving. Crusher product specification was ~80% -2 mm. A
silica rock sample was crushed between each sample and the resultant product discarded in
order to prevent cross-contamination of samples. The jaw crusher was cleaned by means of
compressed air between samples. In addition, a silica blank was processed with each batch
of samples and was taken through the entire process including analysis. This sample is
identified as “Waste Rock” and was used to monitor possible sample preparation
contamination.
A riffle splitter was utilised to riffle out 150-250 g of RC samples. The reject sample
material was stored and labelled in plastic bags and placed into storage.
A sub-sample was then pulverised for ~6 minutes in a Labotec LM2 mill. The barrels were
cleaned with crushed silica rock between samples. The mill product was randomly checked
using a 75 µm screen. The minimum target for the mill product was 90% -75 µm.
The sample was then labelled for analysis and submitted to the analytical laboratory.
The SGS analytical procedure is summarised as follows:-
The sample was matted if required, and was then weighed.
The appropriate amount of the appropriate flux was added and then mixed with the
sample. If required, the reducing power was determined, and then the appropriate
amounts of flour, nitre and silver were added.
The sample was then fused, poured and then cooled. The button was then deslagged. It was
then pounded into a cube and then cupelled until the Doré bead formed.
For Atomic Absorption or ICP-OES analysis the bead was dissolved in aqua regia (3:1
hydrochloric acid to nitric acid). This was then diluted if deemed necessary.
For gravimetric determinations, the bead was parted in a 50% nitric acid solution to remove
the silver.
Data reduction by: Computer, on line, data was fed to the laboratory information
management system with a secure audit trail.
Quality control: Two weighed duplicates, standard reference material and blank for every
furnace batch of 21 samples was automatically assigned by the LIMS system for the full Fire
Assay batch.
Precision: 5% relative precision for samples with Au values greater than 1 g/t was required.
The precision was expected to increase, as the detection level was approached. The
inhomogeneity of some samples might have increased this value.
The laboratories were not audited.

9.3 QUALITY ASSURANCE AND QUALITY CONTROL
SAMREC T3.1 (i), T3.2 (ii), T3.3 (iv)
Blanks, field duplicates and CRMs were allocated to the sampling sequence. From 2006 to 2010, a
duplicate assay was submitted every 10th sample for diamond drilling, or at every 30 m for the RC
drilling, however from the information Minxcon has, it is not clear if there was consistency in the
placement of other control materials. 10% of the total samples consisted of a combination of
duplicates, blanks and CRMs.
The QA/QC summary report, the content of which is reflected in this section of the Report, was
prepared on 07th July 2014 by Mr David Muir of CSA (UK). The QA/QC summary report includes
samples collected from 1st January 1998 to 2nd July 2014. The QA/QC summary report was reviewed
by CSA Global (UK) when they compiled a Technical Report on Fair Bride Mineral Resource Estimate
in 2014. Table 10, Table 11 and Table 12 below shows summaries of samples collected and QA/QC
reference materials that were taken during the project and sent the laboratories, however Minxcon
did not review the QA/QC, but did review the CSA QA/QC report and concur with their findings.

The results of the QA/QC review done by Mr Muir is summarised as follows:-
Laboratory Blanks:-
o No issues for Setpoint and SGS;
o No blank results available for Antech;
Laboratory CRMs:-
o Antech – Acceptable accuracy and precision;
o Setpoint – Acceptable accuracy and precision;
o SGS Barberton – No expected values available;
o SGS Lakefield – Some precision and accuracy issues. CRM SN26 under reporting with
multiple failures;
Client Blanks - Some failures but overall acceptable results. Failures could be mislabelled or
misidentified CRMs;
Xtract Resources PLC
An Independent Technical Report on the Mineral Resources of the Fair Bride Gold Deposit on the 3990C Mining Concession,
Manica Province, Mozambique 34
Client CRMs - Poor precision and accuracy exhibited in most CRMs with multiple failures.
Numerous significant failures which could possibly be attributed to mislabelling of blanks
and CRMs; and
Field Duplicates - Poor correlation but no significant bias. Slight bias to the original samples
at lower grades.
Lab Pulp Checks - No significant bias.
9.4 ADEQUACY OF SAMPLE PREPARATION
SAMREC T3.1 (ii)
Statistical analysis of the results shows no systematic variation between the original and field
duplicate and standards and blanks performed within standard tolerances. If any of the standards or
blanks assayed outside standard tolerances the entire batch was re-submitted for re-assay.
Field duplicates were within the acceptable standard tolerance, which means that the sample
preparation was acceptable. However, no historical information is available on the QA/QC of sub-
sampling preparation and or sample representivity.
No bias with respect to core recoveries was noted. However, in cases where there was excessive
core loss and no representative sample was possible, that particular sample was marked as an
absent value in the modelling process so that there would be no negative bias. In addition to this
the areas that were not sampled as a result of low or no mineralisation were given a value 0.01 g/t
(half the detection limit) so that the neighbouring samples with grade were not smeared into low
grade areas causing a positive bias.
9.5 AUDITS, REVIEWS AND MATERIAL RISKS
SAMREC T3.1 (ii), T3.2 (vi), T3.3 (v)
Minxcon is not aware of any audits that were carried out on the sampling processes and procedures
during the drilling and exploration campaigns. The QA/QC data was however reviewed during the
previous CPRs and found to be acceptable. Minxcon also did not detect any anomalies in this
respect during its validation process of the data. Therefore, Minxcon has not identified any material
risk in the sampling preparation and analysis of the Project.

10 DATA VERIFICATION
SAMREC T3.2 (iv)
10.1 DATA VERIFICATION PROCEDURES
As part of the 2014 Mineral Resource Estimation, Mr Malcolm Titley, Principal Consultant, CSA
Global (UK) Ltd, visited the property following the 2013 drilling campaign on two of the other
deposits which were drilled in the same campaign within the mining concession. After Mr Titley
reviewed the drilling and sampling methodology, he concluded that the drilling and sampling data
was satisfactory for the purposes of Mineral Resource estimation.
Data verification processes completed by Minxcon includes checking of overlapping intervals,
missing and repeat data on geological logs, assay, collar survey, downhole survey.
Mr Uwe Engelmann, Competent Person for this Report, also inspected the Fair Bride Project in
March 2016. During this site visit he verified that the drill core does correlate with the drillhole logs
and sections which form the basis of the geological model as well as the estimation model.
Therefore, the database used for the estimation was deemed appropriate and reliable for the
purpose of the estimation.
10.2 LIMITATIONS ON/FAILURE TO CONDUCT DATA VERIFICATION
No limitation on/failure to conduct data verification process.
10.3 ADEQUACY OF DATA
All the data verified and viewed by Minxcon were considered to be satisfactory for the purposes of
Mineral Resource estimation and adequate for the purposes of Mineral Resource Classification in
accordance with the guidance provided by the SAMREC Code.

11 MINERAL RESOURCE ESTIMATES
11.1 DATA
SAMREC T4.1 (ii, iii, iv), T4.2 (i, ii, vi)
11.1.1 Data Density, Distribution and Reliability
The database supplied by Xtract included historic diamond drilling, RC holes and trench sampling.
The drillhole spacing was found to be approximately at a 25 m spacing across the ore body. The
number of holes and the number of holes utilised in the Mineral Resource estimation is listed in
Table 13. From this set of ds only 94 diamond ds were used with 43 RC holes in the estimation. The
trench sampling was excluded from the evaluation as there was concern with respect to the QA/QC
of these samples due to possible mixing of samples and poor standard performance, perceived poor
reliability. The exclusion of the 123 trench samples from the total of 6,887 samples are viewed as
being minimal and are considered to not have an adverse effect on the estimation. In Table 13 it
shows that from a total of 229 drillholes only 137 were used for the evaluation, as these were the
only holes falling within the mineralised envelope. In Figure 19 the distribution of drillholes around
the Fair Bride orebody can be seen.

QA/QC was performed by CSA (Muir, 2014) and the results and report are tabled in the Technical
Report by Auroch Minerals 2014, the findings of which are discussed in the section 9.3. The results
were reviewed by Minxcon in 2015 and the recommendations with regards the estimation were

observed and implemented. These included the exclusion of the trench sampling from the
estimation due to possible mixing of samples and poor standard performance.
11.1.2 Estimation Techniques
Estimation of the block model utilised Ordinary Kriging to estimate the Mineral Resource. Only
samples falling within the ore boundary wireframe were used for the estimation, and a capping
regime was used where sample values exceeding 20 g/t over a 1 m composite were capped at 20
g/t. Soft boundaries were included to estimate the oxide zone where data points were included
from the transitional zone to inform the oxide zone. A variogram range of 198 m in the long range
and 149 m in the short range was used. The variogram was constrained in the Y range to 11 m to
prevent overestimation across the width of the mineralised zone. The final block estimate utilises a
5 m X 5 m X 5 m block size with sub cell splitting.
11.1.3 Basic Statistics
The data used for the statistics and later estimation only includes samples from within the ore
boundary wireframe. Where sample intervals were included but not sampled, these sample
intervals were assigned a trace value (0.01 g/t). Where samples were captured as core loss these
samples were marked as absent. The basic statistics indicated a mean value of 0.39 g/t and a
histogram distribution to be log-normal for the Au values (Figure 21). The statistics for the length
of the samples indicated that the mean value for these was 1.15 m with a geometric mean of 0.96
m (Figure 20).

11.1.4 Data Capping
Capping statistics was conducted on the data falling within the mineralised ore zone and a range of
0.001 to 47.53 g/t was observed. From the cumulative coefficient of variation plot a discontinuity
was seen to exist at 20 g/t (Figure 22). This was viewed as being the upper limit of the data set and
falls into the 99th percentile and accounts for only eight samples points of the total (Figure 23).

11.1.5 Drillhole Assay Compositing
An analysis of the sample lengths for the drilling falling within the mineralised zone that had been
sampled was conducted, and a mean value of 1.18 m with a geometric mean of 0.99 m was
observed (Figure 24). The compositing interval utilised for the estimation was thus selected to be

at a 1 m interval. In Figure 24 below the 3 m samples represent the 3 m composited samples used
from the RC drilling.
Figure 24: Drillhole Sampling Length Histogram; 1m Composites were Selected
11.1.6 Variogram Analysis
Variography was conducted on the 1 m samples and a 3 structure variogram was produced. This
variogram presented a range of 198 m, 146 m and 11 m in the x,y and z axis directions respectively.

Three weathering domains were logged in the drilling and wireframes were created to separate
these domains. The weathering domains were defined as Oxide, Transitional and Sulphide, where
the sulphide zone showed no weathering and the oxide zone had a high level of weathering, with
the transitional exhibiting gradational weathering between the two extremes.
The oxidised zone estimation was restricted to samples within the oxidised zone and samples falling
midway into the transitional zone due to the gradational nature of the contact, resulting in a soft
boundary estimate. The transitional zone was defined in the drilling and has a global average
thickness of approximately 23 m resulting in a soft boundary limit of 11.5 m for the oxide zone.
The sulphide and transition zones were estimated as a unit due the soft boundary between the
zones. In Figure 28 the boundaries are defined by the drillhole logs for the oxide, transitional and
sulphide are depicted as blue, green and brown. The soft boundary for data selection is defined as
the blue line midway between the oxide and the sulphide zones. All samples for the transitional
and sulphide zones were used for the estimation for the transitional zone and the sulphide zones
respectively.

11.1.8 Density
SAMREC T2.4
Extensive density analysis was conducted but CSA and results may be viewed in the appendix of the
Auroch report. Most of the density determinations were conducted using the
Archimedes/displacement principle on lengths of dry core (whole or half) between 15 cm and 30 cm
in length. Where the core was weathered or porous samples were sealed with wax to ensure that
the measurements reflect dry densities. It is the author’s opinion that the densities assigned to the
zones would be applicable to this study and were therefore used as such. The density assignment
for the different zones were as follows:-
Oxide Zone: 2.57 kg/m3,
Transitional Zone: 2.68 kg/m3; and
Sulphide Zone: 2.79 kg/m3.
These values were then assigned to the block model to determine the bulk dry tonnages for the
block model.
11.1.9 Block Estimation and Block Size
SAMREC T4.2 (iii)
The orebody wireframe was filled with cells of dimensions: 5 m X 5 m X 5 m with sub cell splitting.
The cell size was selected due to the smallest mining unit (“SMU”) size and the kriging efficiency. A
cell size of 15 m X 5 m X 15 m produced a better kriging efficiency yet the degrees on efficiency did
not significantly change with the change in the block size, therefore for later reserving purposes
the 5 m X 5 m X 5 m cell size was selected.
Xtract Resources PLC

Manica Province, Mozambique 44
A number of estimations were conducted including: ordinary kriging, inverse distance and nearest
neighbour. Ordinary kriging was selected as the preferred estimation method as a robust variogram
could be generated and the kriging efficiency was observed as being satisfactory to ensure a robust
estimation. Estimation was done on the parent cells and these values were assigned to the relevant
sub cells.
In Figure 29 the total resource model (in g/t) is shown with the high grade area to the west of the
orebody. A section (Figure 30) through the resource model shows how the estimation is honouring
the narrow zones of mineralization. In the horizontal section of elevation 500 m (Figure 31) the
western high grade are is clearly seen as compared to the eastern limb of the orebody.

11.1.10 Checking and Validation
SAMREC T4.2 (iv, v)
Swath plots across the orebody from east to west (Figure 32) as well as sections (Figure 33) at
different elevations through the orebody were generated in order to compare the estimated values
to the original assay values. These indicated a good correlation with regards the estimation and the
raw assay values. Visual cross section of the drilling and resource block model was done to ensure
the estimation honoured the drillhole sampling.
This was viewed as presenting acceptable variation making the estimation acceptable for the type
of deposit and the sample spacing encountered in the deposit. It is apparent however that the
estimate consistently slightly under-evaluates orebody due to the smoothing effect of the kriging
estimate.

11.1.11 Classification Criteria
SAMREC T7 (i, iii)
Classification for the estimation was based on the following criteria (Table 15):-
Kriging efficiency;
Number of samples; and
Search range of the variogram.
Table 15: Classification Criteria
Item Mineral Resource Category
Measured Indicated Inferred
Kriging Efficiency >0.5 >0.3 <0.3
Minimum No Samples 20 10 10
Search Radii 1 1 2
Where the criteria were met the model was flagged and coded. The coding was then used to inform
a classification halo wireframe that was created to ensure that no erroneous blocks were classified
as Measured, although they may have satisfied the coding criteria in Table 15. These wireframes in
Figure 34 were then used as the final classification of the Fair Bride Mineral Resource estimation
block model. Any resource block that falls within the Measured wireframe was classified as
Measured and blocks falling outside of the Measured but within the Indicated wireframe is classified
as Indicated. Resource blocks falling outside of these classification wireframes are classed as
Inferred. The Inferred Resources was stopped at twice the search radii and any Mineral Resource
estimation beyond this was unclassified. The final classification model is shown in Figure 35. This
classification criteria extends the resource model to a depth of approximately the 200 m amsl
elevation, which is approximately 530 m below surface.

A minimum of at least two drillholes per estimation was incorporated in the estimation to prevent a
single drillhole having undue weight on the estimation.

The above classification criteria have taken into consideration the accuracy of the tonnage by
means of the lithological wireframes (volume) and the density for the various zones (oxide,

transition and sulphide). The quality of the data is deemed to be sufficient based on the QA/QC
procedures incorporated into the exploration programme and finally the confidence of the
estimation by considering the kriging efficiencies of the model. The continuity of the orebody is
based on the Inferred Mineral Resource being based on twice the semi variogram range, which is an
acceptable practice, and this type of orebody is known to have depth extension.
11.2 DISCLOSURE REQUIREMENTS FOR MINERAL RESOURCES
SAMREC T8 (i)
All Mineral Resources have been categorised and reported in compliance with the definitions
embodied in the SAMREC Code on the reporting of Mineral Resources and Mineral Reserves. Mineral
Resources have been reported separately in the Measured, Indicated and Inferred Mineral Resource
categories. Inferred Mineral Resources have been reported separately and have not been
incorporated with the Measured and Indicated Mineral Resources.
The Mineral Resources are exclusive of Mineral Reserves.
11.3 INDIVIDUAL GRADE OF METALS
SAMREC T4.2 (vi)
The only metal considered in this Mineral Resource estimate for Fair Bride is gold. No other metals
or metal equivalents were estimated or calculated. However, the presence of arsenopyrite was
utilised for the delineation of the orebody lithological wireframes.
11.4 MINERAL RESOURCE TABULATIONS
SAMREC T4.1 (iv), T7 (v), T8 (ii)
The Mineral Resource for Fair Bride for 2016 is tabled below in Table 16 to Table 18. The Mineral
Resource is based on a total resource stated at a cut-off of 0.5 g/t. The Mineral Resources are
further sub-divided into a Surface Minable Mineral Resource and an Underground Mineable Mineral
Resource. Two cut-offs were used for this classification. The results provided below appropriately
reflect the Competent Person’s view of the Fair Bride orebody.

The surface resource is based on a NPV scheduler optimisation run of an open pit design. This
optimisation run resulted in two pits, one to a depth of 220 m and the second to a depth of 350 m
(Figure 36). Therefore, an average of 280 m was used to limit the surface resource for declaration
purposes.

In addition to the depth cut-off, the grade cut-off used was 0.5 g/t. This is based on a gold price of
USD1,466/oz, which is the 90th percentile of the historical real term commodity prices since 1980,
and a mining cost and processing cost of USD1.76/t and USD22.5/t respectively. The recoveries
used in the Mineral Resource cut-off were 95.6% for the oxides and 90% for the transition and
sulphide zones. The underground Mineral Resource is based on a 1.5 g/t cut-off which used the
same gold price and recoveries but is based on a mining cost of USD27.12/t and USD22.07/t
processing cost.

11.5 FACTORS AFFECTING MINERAL RESOURCE ESTIMATES
SAMREC T8 (iii)
Downhole surveys were not conducted on all the holes and this might influence the local accuracy
of the mineralised zone, as the two long holes ANDD039 and ANDD037 show significant deviation.
An extensive density analysis was conducted but CSA and results are in the appendix of the Auroch
report. It is the opinion of the authors of this Report that the densities assigned to the zones would
be applicable to this study and therefore used as such. The density assignments for the different
zones are thus Oxide Zone 2.57 kg/m3, Transitional Zone 2.68 kg/m3 and Sulphide Zone 2.79 kg/m3.
These values were then assigned to the block model to determine the bulk dry tonnages for the
block model.
The historical pits and underground development voids have been removed from the Mineral
Resource estimation. Underground mining is very limited and consists of minor adits and drives and
therefore no pillars due to historical mining have been demarcated or removed from the resource.
No geological fault loss factor has been applied to the Mineral Resource estimation at this stage.
11.6 MINERAL RESOURCE RECONCILIATION 2014-2016
SAMREC T8 (iv)
Table 23 shows the reconciliation between the Auroch Mineral Resource estimate for Fair Bride in
2014 and the 2016 Mineral Resource estimate. The reasons for the changes for the Mineral Resource
estimation included:-
The change in the estimation method from Local Uniform Conditioning to Ordinary Kriging;
Depth change of the resource declaration from 350 m to approximately 530 m below surface;
Change of resource wireframe to honour geological interpolation; and
Revised variogram and statistics.

12 CONCLUSIONS
Minxcon has the following conclusions regarding the Mineral Resources of the Fair Bride Project:-
The database is a reliable database for Mineral Resource Estimation;
After discussions with the project geologist no fault was interpreted between the eastern
and western portions of the main (higher grade) Fair Bride orebody – this area potentially
requires further investigation;
Downhole surveys were not conducted on all the holes and this might influence the local
accuracy of the mineralized zone, as the two long holes ANDD039 and ANDD037 show
significant deviation;
The mineralised strike of the ore body is approximately 1,040 m;
Open pit resource has been declared to a depth of 280 m (which is the average depth of the
two modelled pits) – resource cut-off of 0.5 g/t;
The open pit is predominantly Measured and Indicated Mineral Resource;
The depth extension (underground resource) is predominantly in the Inferred Mineral
Resource category and is to a depth of approximately 530 m;
Currently the densities utilised are based on the oxide, transition and sulphide zones. There
is no split in the densities on lithology type – especially the BIFs and rhyolites that make up
the majority of the orebody;
The 2016 Mineral Resource has a grade similar to that of the 2010 resource estimation but
is lower than the 2014 Mineral Resource estimation. This is due to the fact that the 2014

13 RECOMMENDATIONS
SAMREC T10 (i)
The following recommendations are made:-
The underground resource, which is predominantly in the Inferred Mineral Resource
category, requires infill drilling to improve the confidence levels;
The additional drilling for the depth extension should be surveyed down the hole as the
previous long holes show significant deviations;
Additional drilling is required at the western portion of the strike to investigate if the depth
extension is also low grade;
The difference in the densities of the lithologies should be investigated to assess the
impact;
It is the author’s opinion that the ordinary kriged model should be utilised for mine design
as it gives a more realistic mining grade model.

The following terms are used in this Report:-
SAMREC T10 (ii)
Term Definition
Alluvial The product of sedimentary processes in rivers, resulting in the deposition of alluvium (soil deposited by a river).
Arenite A sedimentary rock composed mainly of quartz minerals.
Argillite A sedimentary rock composed mainly of clay minerals.
Assay laboratory A facility in which the proportions of metal in ores or concentrates are determined using analytical techniques.
Auriferous A synonym for gold-bearing.
Conglomerate A sedimentary rock containing rounded fragments (clasts) derived from the erosion and abrasion of older rocks. Conglomerates are usually formed through the action of water in rivers and beaches. The interstitial spaces between the clasts are filled with finer grained sediment.
Cut-off grade Cut-off grade is any grade that, for any specific reason, is used to separate two courses of action, e.g. to mine or to leave, to mill or to dump.
Development Activities related to preparation for mining activities to take place and reach the required level of production.
Diamond drilling An exploration drilling method, where the rock is cut with a diamond drilling bit, usually to extract core samples.
Dilution Waste which is mixed with ore in the mining process.
Dip The angle that a structural surface, i.e. a bedding or fault plane, makes with the horizontal. It is measured perpendicular to the strike of the structure.
Exploration Prospecting, sampling, mapping, diamond drilling and other work involved in the search for mineralisation.
Facies The features that characterise rock as being emplaced, metamorphosed or deposited in a sedimentary fashion, under specific condition. In the case of sediment host deposits, this infers deposition within a particular depositional environment.
Faulting The process of fracturing that produces a displacement within, of across lithologies.
Grade The quantity of metal per unit mass of ore expressed as a percentage or, for gold, as grams per tonne of ore.
In situ In place, i.e. within unbroken rock.
Indicated Mineral Resource
An “Indicated Mineral Resource” is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and ds that are spaced closely enough for geological and grade continuity to be reasonably assumed (NI 43-101 definition).
Inferred Mineral Resource
An “Inferred Mineral Resource‟ is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and ds.
Internal Rate of Return (IRR)
The internal rate of return on an investment or project is the "annualised effective compounded return rate" or "rate of return" that makes the net present value of all cash flows (both positive and negative) from a particular investment equal to zero. It can also be defined as the discount rate at which the present value of all future cash flow is equal to the initial investment or in other words the rate at which an investment breaks even.
Kriging An estimation method that minimises the estimation error between data points in determining mineral resources. Kriging is the best linear unbiased estimator of a mineral resource.
Level The workings or tunnels of an underground mine which are on the same horizontal plane.
Lithology The general compositional characteristics of rocks.
Measured mineral resource
“Measured Mineral Resource‟ is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and ds that are spaced closely enough to confirm both geological and grade continuity.
Mineable That portion of a mineral resource for which extraction is technically and economically feasible.
Mineral Reserve A Mineral Reserve is the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. Adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. (NI43-101
Xtract Resources PLC

Manica Province, Mozambique 63
Term Definition
definition). Mineral reserves are reported as general indicators of the life of mineral deposits. Changes in reserves generally reflect:
i. development of additional reserves; ii. depletion of existing reserves through production; iii. actual mining experience; and iv. price forecasts.
Grades of mineral reserve actually processed from time to time may be different from stated reserve grades because of geologic variation in different areas mined, mining dilution, losses in processing and other factors. Neither reserves nor projections of future operations should be interpreted as assurances of the economic life of mineral deposits or of the profitability of future operations.
Mineral Resource A Mineral Resource is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilised organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge.
Mineralisation The presence of a target mineral in a mass of host rock.
Mineralised area Any mass of host rock in which minerals of potential commercial value occur.
Ore A mixture of valuable and worthless minerals from which at least one of the minerals can be mined and processed at an economic profit.
Mineral Deposit A continuous well defined mass of material of sufficient ore content to make extraction economically feasible.
Outcrop The exposure of rock on surface.
Reef A narrow gold-bearing lithology, normally a conglomerate in the Witwatersrand Basin that may contain economic concentrates of gold and uranium.
Sampling Taking small pieces of rock at intervals along exposed mineralisation for assay (to determine the mineral content).
Sedimentary Formed by the deposition of solid fragmental material that originates from weathering of rocks and is transported from a source to a site of deposition.
Semi-variogram A graph that describes the expected difference in value between pairs of samples as a function of sample spacing.
Stratigraphic A term describing the chronological sequence in which bedded rocks occur that can usually be correlated between different localities.
Strike length Horizontal distance along the direction that a structural surface takes as it intersects the horizontal.
Sulphide A mineral characterised by the linkages of sulphur with a metal or semi-metal, such as pyrite (iron sulphide). Also a zone in which sulphide minerals occur.
Syncline A basin shaped fold.
Syndepositional A process that took place at the same time as sedimentary deposition.
Tonnage Quantities where the tonne is an appropriate unit of measure. Typically used to measure reserves of gold-bearing material in situ or quantities of ore and waste material mined, transported or milled.
Total cost per ounce
A measure of the average cost of producing an ounce of gold, calculated by dividing the total operating costs in a period by the total gold production over the same period.
Transgress Systematic inundation of an erosional surface by sedimentary deposition.
Unconformity A surface within a package of sedimentary rocks which may be parallel to or at an angle with overlying or underlying rocks, and which represents a period of erosion or non-deposition, or both.
Waste rock Rock with an insufficient gold content to justify processing.
