Minxcon (Pty) Ltd (“Minxcon”) was commissioned by Free State Development and Investment Corporation
Limited (“FSD”) to update an Independent Mineral Asset Valuation Report on the mineral assets of the Du
Preez Leger Project, located near the town of Welkom, Free State Province, South Africa. The Report is
fully compliant with the South African Code for the Reporting of Exploration Results, Mineral Resources
and Mineral Reserves (“the SAMREC Code”), the South African Code for the Reporting of Mineral Asset
Valuation (“the SAMVAL Code”) and Section 12 of the JSE listing requirements, with the exception of
sections pertaining to developed operations as this Project is still in the exploration phase. The
Competent Person of the Valuation Report deems this summary document to be a true reflection of the
content of the full Report.
The Du Preez Leger Project comprises four exploration
areas in the Free State Province; namely the Du Preez
Leger/Jonkersrust 72 (“Du Preez Leger”) area, the
Vermeulenskraal area, the Rebelkop area and the
Tweepan area. Due to the limited information
available regarding the Rebelkop area, this area has
not been evaluated for a Mineral Resource.
The areas of interest are located Free State Goldfield
of the Witwatersrand Basin, with adjacent producing
gold mines including the President Steyn Gold Mine,
Bambanani Mine, Harmony Mine, Beatrix Mine and St
Helena Mine. These mines have mainly targeted the
Basal and Leader Reefs. The A-Reef has also been
extensively mined on Brand Mine to the north of the
Project Area. The placers of primary economic
interest at the Project Area are the Basal and Leader
Reefs.
FSD has held the mineral rights pertaining to the Project Area („old order rights‟) since the early part of
the twentieth century circa 1945. These rights were converted to a New Order Prospecting Permit on 7
November 2006, under the Mineral and Petroleum Resources Development Act, 2002. The New Order
prospecting permit expires on 6 November 2011. No invasive physical exploration activities have been
conducted by FSD to date, and accordingly the environment has not been impacted.
Proposed further work on the Project will include an in-depth review of the available data by a competent
geological consulting company with the possible progression, depending upon the results of the aforesaid
review, to drilling of up to four geological boreholes as envisaged in the Prospecting works Programme.
The estimated funding requirements for exploration for the 2009-2010 combined year is ZAR 5.185 million
and for 2011 is ZAR 350,000. The Company has sufficient cash resources to fund future exploration and
environmental work.
No account of any modifying factors such as mining methods, metallurgical treatment processes and
parameters, taxation, socio-economic, marketing or political factors have been taken into account.

RESOURCE EVALUATION
The Resource evaluation was undertaken using Minxcon‟s „Mt-Estimation‟ geostatistical program which
utilizes DatamineTM as the platform software. Full reef composite mining cut values (Au content (cm.g/t))
have been interpolated into a 2D block model. The block model size of 500 X 500 m was determined from
the drill hole spacing, and the continuous nature of the ore body („stationarity‟ principal). Simple kriging
estimation technique was used, based primarily on drill hole spacing. Detailed checks were carried out to
validate kriging outputs, including input data, kriged estimates and kriging efficiency checks.
Four geostatistical domains (geozones) were modelled for the Basal Reef and eleven geozones were
modelled for the Leader Reef, based on the grade relationships and data trends of the boreholes.
The drill holes represent full reef composites, i.e. one intersection value per drill hole. The composite was
then used in the estimation process.
The November 2008 Minxcon estimated block models were depleted based on regional structure data and
the Mineral Resource was subsequently adjusted accordingly.
The table below details the Mineral Resource with regards to reef versus Resource cut (minimum stoping
width of 120cm) both at a zero cut-off and a cut-off of 250cm.g/t:-

3.1.1 Access and Infrastructure
The Project area is located south of the town of Welkom, and is approximately three hours drive from the
city of Johannesburg. Welkom is accessible by road, rail or air. The main road structure to and around the
project are in good condition; the Du Preez Leger and Vermeulenskraal deposits can be accessed via the
R34 main road through the town of Welkom.
The main electric railway line in this area is the Bloemfontein–Virginia-Johannesburg line, and an airport
and 13 airstrips are situated in the area.
Power is supplied by ESKOM, and Sedibeng Water supplies water mainly from the Vaal River. Sedibeng
Water is a state owned company which was opened in 1979. Limited mid-term power availability may
constrain development of new mining projects in the region. The location of the two deposits, as well as
the general infrastructure of the area, is illustrated in Figure 2.
3.1.2 Topography and Climate
The Free State experiences a continental climate, characterized by warm to hot summers and cool to cold
winters. Areas in the east can experience snowfalls in the winter months, whereas the western areas are
prone to extremely hot summers. The area receives summer rainfall. The climatic conditions are not
excessively extreme, and mining operations can continue throughout the year.
The surface topography of the area surrounding Welkom is characterized by gently undulating plains. The
Du Preez Leger Project is situated at an elevation between 1,300m above sea level (“asl”) and 1,340masl
(Figure 3).
3.1.3 Adjacent Properties
The mines adjacent to the Du Preez Leger Project area are predominantly owned by Harmony Gold Mines
Ltd. These include: the Bambanani Mine, the St Helena Mine and the Harmony Gold Mine as well as the

extent of 913.5028ha became known as Vermeulens Kraal (or Vermeulenskraal) 223 in the District of
Ventersburg at some time between 1924 and 1939.
3.5 Environmental Aspects
No invasive physical exploration activities have been conducted by FSD to date, and accordingly the
environment has not been impacted.
The original Environmental Management Programme (“EMP”) was approved by the Regional Manager, Free
State Region of the DME, Welkom, on 1st September 2005 as indicated in Appendix 4. The environmental
rehabilitation liabilities could include the restoration of the possible borehole sites in an estimated
amount of ZAR40,000 (forty thousand rand). Funding for such environmental rehabilitation has been
proposed in the overall project budget and a Bank Guarantee (as required by the regulations to the
MPRDA) in the amount of ZAR10,000 (ten thousand rand) has been lodged with the DME.
3.6 Agreements
An Offer to Purchase Agreement was signed on 17 February 2010 between FSD and Witwatersrand
Consolidated Gold Resources Limited (“Wits Gold”). Pursuant to this Agreement, Wits Gold holds the
option to purchase rights to the Tweepan 678 -Millo 693 property.

FSD has held the mineral rights pertaining to the Project area („old order rights‟) since the early part of
the twentieth century circa 1945. These rights were converted to a New Order Prospecting Permit on 7
November 2006, under the Mineral and Petroleum Resources Development Act, 2002. The New Order
prospecting permit expires on 6 November 2011.
FSD has undertaken historical exploration at the project area but no production has taken place and no
infrastructure exists.
4.1 Historical Exploration and Sampling Methods
The four prospects have different exploration histories. On Vermeulenskraal, three exploration phases
took place. During the late 1940‟s, FSD sunk a single borehole (HV1) on the boundary of Vermeulenskraal
223 and Hakkies 735 which intersected Leader Reef as well as faulted successions. Rand Mines completed
a second phase of drilling in March 1975. Six surface holes (VL1 to VL6) as well as three underground holes
were drilled from the boundary of Harmony Gold Mine. The third phase of exploration was a haulage
developed from Merriespruit 1 Shaft which exposed 422m of Leader Reef. This was the only reef exposed.
On the Du Preez Leger prospect, fourteen boreholes within or adjacent to the property have been used for
evaluation purposes of the Leader Reef. The Basal Reef has only been intersected in 3 boreholes. This is
due to most of the area being south of the Basal/Leader Reef subcrop.
There is no record of previous drilling on Tweepan or Rebelkop; thus the grades have been estimated from
mining and drilling values available on adjoining properties.
The original hard copy borehole logs for the Vermeulenskraal holes are available from FSD. The original
data was not supplied to Minxcon. Electronic information is available for the other prospects. This
information was however not validated by Minxcon against the original data as it is beyond the scope of
this resource estimation. The positions of the Leader-Basal Reef subcrop and prospects were also made
available in electronic format. The holes on Vermeulenskraal were drilled by FSD and Rand Mines, whilst
the holes on the Du Preez Leger prospect were drilled by Anglo American.
Details of historic borehole surveys, sampling methods, drilling techniques, sample recovery, logging
techniques and other sources of information were not available. No details regarding the Quality
Assurance and Quality Control (“QA/QC”) for the sampling and assays were available. Minxcon did not
receive any details regarding the assay laboratory and assaying procedure. As such, there can be no
comment on the integrity of sampling results, but this is relied upon as being accurately recorded by
current and previous Project owners for evaluation purposes.
The exploration cost to date for the Du Preez Leger Project is ZAR327,459.
4.2 Current Exploration
There is no invasive physical exploration currently being conducted at the Project area.

5.1 Regional Geology
The Witwatersrand Basin is located in the Kaapvaal Craton, South Africa. It represents a remnant of a
large Achaean sedimentary basin that hosts the world‟s largest gold reserves within a series of
conglomerate horizons. The Witwatersrand Basin comprises a 60,000km2 Northeast trending elliptical
structure, extending from the east of Johannesburg to south of the town of Welkom (Figure 4).
The basin is the largest known gold province in the world and the deposits have been exploited for in
excess of on hundred years. Gold is currently produced from seven of eight goldfields within the basin,
mainly from conglomerate horizons of the Witwatersrand, Ventersdorp and Transvaal Supergroups. The Du
Preez Leger Project is situated in the Free State Goldfield and is situated on the southern edge of the
Witwatersrand Basin.
The Witwatersrand Supergroup is underlain by an Archaean (>3.1Ga) granite-greenstone basement and the
3.086–3.074Ma Dominion Group. It is unconformably overlain by rocks of the Ventersdorp (2.7Ga),
Transvaal (2.6Ga) and Karoo (302-180Ma) Supergroups. The Witwatersrand Supergroup is divided into two
groups, the West and Central Rand Groups. The reefs that occur at the Project area are located within the
Central Rand Group (“CRG”).
The CRG unconformably overlies the West Rand Group. Lithologies in this group are characterised by
sandstone and conglomerate which dominate over shale. The CRG comprises the Turfontein and
Johannesburg Subgroups, which both contain conglomerates in their lower and upper portions. At least
ten basin wide unconformities are known, each overlain by conglomerate beds. The conglomerates of the
CRG contain a variety of pebble types. A distinctive feature of the conglomerates is an overall increase in
clast size, recorded from the base to the top of the group.

5.2 Local Geology
The Free State Goldfield lies approximately 270km from Johannesburg on the southwest rim of the
Witwatersrand Basin.
The dominant structural features of the Free State Goldfield are the north-northwest striking Ventersdorp
age normal faults, such as the De Bron fault, and the north-south trending syncline developed along the
western margin of the gold field (The Mineral Resources of South Africa, 1998). This syncline extends
across the entire North-South span of the Free State Goldfield, and is associated with several reverse
faults such as the Rheedersdam fault. Compression associated with this faulting led to the occurrence of
severely deformed, and in some places, overturned Witwatersrand sediments on the western edge of the
Free State Goldfield, and therefore complicates the exploration and/or mining of gold in this area.
The post-Witwatersrand faulting, represented by normal faults such as the De Bron and Homestead faults,
form the De Bron horst. This block of uplifted lower Witwatersrand sediments demarcate the eastern
boundary to mining in the Free State Goldfield.
The ore bodies of the Free State Goldfield occur within the CRG, and the major gold-producing unit is the
Basal (or Steyn) Reef, which together with the Leader Reef, occurs throughout the goldfield. Other
important economic horizons are the A, B and Eldorado Reefs (Figure 5).

5.3 Project Geology
The Project is located in an area which has been extensively mined for gold, and the local geology is
therefore considered to be fairly well understood and interpreted. The placers of primary economic
interest at the Project area are the Basal and Leader Reefs. Other reefs found in this area include the A
and B Reefs, BPM (Sand River Reef), Aandenk and VS5/Beatrix Reefs. The Vermeulenskraal prospect lies
just to the south of the Sand River and is to the west of Harmony Mine. The Du Preez Leger prospect lies
to the south of the Harmony Brand and St Helena mines, and to the west of the Harmony Unisel Mine.
These mines have mainly exploited the Basal and Leader Reefs. The A-Reef has also been extensively
mined on Brand Mine to the north of the Project area.
The other two prospect areas comprise Tweepan (comprising the farms Millo 693 and Tweepan 678) and
Rebelkop. Limited information is available for these two prospects.
Tweepan is located south of the Harmony Merriespruit mine, and Rebelkop is situated to the east of the
Harmony Virginia mine. Leader Reef is developed on both of these areas. The Basal Reef on Tweepan is
developed only on the farm Tweepan 678 and not on farm Millo 693. B Reef is also developed only on
Tweepan.
The sizes of the prospects as listed previously are: Vermeulenskraal: 913 Ha, Du Preez Leger/ Jonkersrust:
1,101 Ha, Millo/Tweepan: 355 Ha and Rebelkop: 689 Ha.
5.3.1 Stratigraphy
The sediments of the Central Rand Group are overlain by the Karoo and Ventersdorp Supergroup rocks in
the Project area. The Karoo sediments at the Project area varies in thickness from 550-700m. These are
underlain by the lavas and sediments of the Ventersdorp Supergroup, which are mainly comprised of
andesitic lavas of the Klipriviersberg Group. In places these have been eroded by Ventersdorp sediments
of the Klippan Formation (thick sequences of poorly sorted debris flows). Towards the south of the
Welkom Goldfield, there has been a thinning of the Central Rand Group stratigraphy and the Basal Reef
subcrops against the Leader Reef, which is developed over the entire Project area. This subcrop results in
Basal Reef only being formed on approximately 45% of Vermeulenskraal and on a little over 10% of the Du
Preez Leger prospect.
There is less information available on the overlying stratigraphy of the Central Rand Group on the
prospects south and east of the Harmony Merriespruit and Virginia mines, but these would also comprise
Karoo and Ventersdorp Supergroup rocks. Tweepan is characterised by Central Rand Group sediments
underlying the entire property and Rebelkop by Central Rand Group underlying approximately 70% of the
area.

5.3.2 Structure
The economic reefs are found at different depths below surface. On Vermeulenskraal, the Basal Reef
varies in depth from 2,100m to 2,350m to the west of the NNE-SSW trending Vermeulenskraal Fault, whilst
to the east the depth varies between 1,400m and 2,000m. The reefs dip on average approximately 15°
towards the east, but local variations have been noted. The Leader reef overlies the Basal Reef at varying
distance intervals, with the Basal Reef eventually subcropping against the Leader Reef to the south of the
property – on a roughly east-west trend. On the Du Preez Leger prospect, the Basal Reef is found at depths
of between 1,000m and 1,200m. The Leader Reef is found at depths between 1,000m and 1,900m. The
dips of the reefs are to the east on St Helena and Unisel mines, which are contiguous to the north and east
of the Du Preez Leger prospect area, and vary between 20 and 45°. On Tweepan, the Leader Reef is found
to be 1,200m to 2,300m below surface. The Basal reef on Tweepan is 1,300m to 2,300m deep, whilst the B
Reef is located at depths between 1,300 and 2,300m. On Rebelkop, the Leader Reef is present at depths
between 1,100m and 2,000m.
The general structure of the Welkom Goldfields comprises north-south normal faults which successively
displace the orebodies downwards to the west. The regional dip is 15° towards the east but variations are
caused due to local structural controls. These dips are found to be almost vertical along the western
margin to very flat-lying in the eastern parts of the goldfield. The largest of these faults is the De Bron
Fault, which transects the Tweepan prospect. The Du Preez Leger and Vermeulenskraal prospects are to
the west of this fault, whilst Rebelkop is to the east. The displacement along this fault is in the order of
1,000m. The local structural environment of the Vermeulenskraal prospect is dominated by the NNE-SSW
trending normal Vermeulenskraal Fault as well as associated sub-parallel faults. They display downward
displacements to the west. The Du Preez Leger prospect is located west of the Stuurmanspan Fault. This is
another large normal fault which displays strong dextral lateral shifts too. On Unisel and St Helena mines
large scale E-W thrusting has been noted, thus causing duplication of the ore body towards the south. The
potential for the occurrence of similar structures on the Du Preez Leger Project is great.

5.4 Mineralisation at the Project Area
The Basal Reef, which is the major ore horizon of the Free State goldfield, varies in character in different
parts of the goldfield. In general, it is thicker and more robust in the south, where it may consist of several
bands of conglomerate with interstitial quartzite layers, the total reef package being up to 1.5m thick in
the south of President Brand and President Steyn leases and up to 3m thick in the Virginia-Merriespruit
area. Gold mineralisation is often associated with fairly coarse buckshot pyrite. The reef thins towards the
north to often not more than a few centimetres and is usually a single band of conglomerate or coarse grit
with associated carbon. Scour channels, both pre- and post-Basal Reef in age, are fairly common,
especially in the eastern sector.
The Leader Reef is a persistent conglomerate, present over the entire Free State Gold Field, which usually
carries low amounts of gold. It has been mined in certain localised areas and is likely to contribute to a
portion of ore reserves in the future as it is in stratigraphic proximity to the Basal Reef and as a result does
not require significant additional underground development to explore and exploit.
The A Reef and the B Reef, both in the Kimberley Stage, are widespread but have not been extensively
mined although rich patches of B Reef have historically been exploited in the northern part of the goldfield.
The Elsburg Reefs consist of lenses of auriferous conglomerate occurring in a thick quartzite succession. The
Elsburg Reefs (or Rainbow Reefs) differ from the normal, essentially barren, Elsburg conglomerate beds
(locally referred to as zones VS 1 to VS 4) with which they are correlated; whereas the pebbly constituents
of the latter consist of a variety of rock types, those of the former are composed of quartz and chert
pebbles, or may pass into grit essentially composed of quartz and chert fragments. It is believed that older

Witwatersrand reefs, which were truncated and eroded along the western side of this goldfield,
contributed the gold in these reefs.

6.1 Density Estimation
A density of 2.7t/m3 was applied to the Mineral Resource estimates. This value is based on an average
known density for Witwatersrand ore bodies.
6.2 Grade Estimation
6.2.1 Domaining
In order to understand geostatistical estimation, the data should represent homogeneous population
distributions, which are dependent on the geological understanding of the ore body/bodies. Typically the
zones utilised in estimation (geozones) are derived from geological domains and are dependent on the
scale being estimated to, and may or may not redefine the geological domains. The domains are used to
constrain the statistical and geostatistical analysis that form the basis of the estimation process.
The Basal and the Leader reefs were reviewed with the aim of delineating broad scale gold geozones. The
gold domains were thoroughly investigated and modelled by the CPs. Each of the reefs was delineated
according to the variability of the channel width (CW), gold content and gold grade.
Four geostatistical domains (geozones) were modelled for the Basal Reef and eleven geozones were
modelled for the Leader Reef, based on the grade relationships and data trends of the boreholes (Figure
15 and Figure 16).

6.2.2 Compositing
The drillholes represent full reef composites, i.e. one intersection value per drill hole. The composite was
then used in the estimation process.
Mineral Asset Valuation Report on the Du Preez Leger Project
Prepared by Minxcon (Pty) Ltd
29
6.2.3 Geostatistical Evaluation Method
The following applies to the Resource area and was undertaken using Minxcon‟s ‘Mt-Estimation’
geostatistical program which utilizes DatamineTM as the platform software. Full reef composite mining cut
values (Au content (cm.g/t)) have been interpolated into a 2D block model. The block model size of
500X500m was determined from the drill hole spacing, and the continuous nature of the ore body
(„stationarity‟ principal). Simple kriging estimation technique was used, based primarily on drill hole
spacing. Detailed checks were carried out to validate kriging outputs, including input data, kriged
estimates and kriging efficiency checks.
The following parameters were used in the kriging process for both reef horizons:
Point data – metal content (Au (cm.g/t)) and thickness (cm);
500m x 500m x 1m block size (X,Y,Z);
Subcells employed;
Parent cell estimation;
Discretisation 5 x 5 x 1 for each 500m x 500m x 1m block;
First search volume – approximately 1.5 times the variogram range (m);
o Minimum number of samples 4 in search volume one (SVOL1);
o Maximum number of samples 40 in search volume one (SVOL1);
Second search volume 1.5 times first search volume;
o Minimum number of samples: 2;
o Maximum number of samples: 40;
Third search volume was not employed due to drill hole spacing being adequate for search
volumes 1 & 2;
Interpolation method – Simple kriging; and
Metal Grade (Au g/t) was calculated from metal content and mining width.
6.2.4 Assumptions and Adjustments
The Basal Reef and Leader Reef at the Project Area are defined as consistent tabular ore bodies across the
Project Area, which allowed a 2 dimensional (“2D”) approach to the Mineral Resource estimation. Simple
kriging estimation was employed. The estimation process utilised the gold metal content (cm.g/t) and
thickness (cm). Figure 17, Figure 18 and Figure 19 illustrate drill hole positions over the Project Area.

A total of 110 accepted Basal Reef and 135 Leader Reef intersections were available for the Mineral
Resource estimation, of which 15 Basal Reef intersections fell within the Resource area, and 124 Leader
Reef intersections fell within the Resource area. The average distance between drill holes varied between
600m and over one kilometre. The gold metal grade was estimated from metal content and mining width.
No audits or reviews have been conducted on the data used in the Mineral Resource estimation. True
widths of reef intersections were used for the Mineral Resource estimation.
6.2.5 Statistical Analyses
Statistical analyses were performed on the gold content (Au cm.g/t) and mining width (cm) of each
domain within the Project Area, to develop an understanding of the statistical characteristics and sample
population distribution relationships. Descriptive statistics in the form of histograms (frequency
distributions) and probability plots (used to evaluate the normality of the distribution of a variable) were
used to develop an understanding of such statistical relationships (refer to Appendix 6). Negative values in
the tables below represent log space values.

6.2.6 Co-Efficient of Variation
The Co-efficient of Variation (“CoV”) is the ratio between the standard deviation and the mean and is a
relative measure of dispersion in a data set. Typically a CoV <1 indicates low variance within the data set.
A low variance data set demonstrates that the population distribution reflects a relatively homogenous
data set which is necessary for estimation purposes.

6.2.7 Variography
Variograms are an essential tool for investigating the spatial relationships of samples. Variograms for
metal content (Au cm.g/t) and mining width (“CW”) were modelled. Anisotropy was investigated,
although all variograms are deemed best represented by omni-directional models. The tables below
summarise the variogram model parameters for the Resource area.

Cutting/Capping
Cutting/capping of outlier data is undertaken in the variography process in order to model the population
variance which is not unduly influenced by outlier values. No Capping or cutting is undertaken during the
kriging exercise. Use of the log normal and normal probability plots aids in determining the outliers that
would be capped/cut in the variography stage. The following domains were capped/cut in the variography
process:-

6.2.8 Resource Classification
The accuracy of the Mineral Resource classification is a function of the confidence levels inherent in the
entire process comprising drilling, sampling, geological understanding and geostatistical relationships. The
following aspects or parameters were considered for Mineral Resource classification:
1. Sampling – quality assurance & quality control (QA/QC):
a. Measured: high confidence, no problem areas;
b. Indicated: high confidence, some problem areas with low risk;
c. Inferred: some aspects might be of medium to high risk.
2. Geological confidence:
a. Measured: high confidence in the understanding of geological relationships,
continuity of geological trends and sufficient data;
b. Indicated: Good understanding of geological relationships;
c. Inferred: geological continuity not established.
3. Number of samples used to estimate a specific block:
a. Measured: at least 4 boreholes within variogram range and minimum of twenty
one-metre composited samples;
b. Indicated: at least 3 boreholes within variogram range and a minimum of twelve
one-metre composite samples;
c. Inferred: less than 3 boreholes within the variogram range.
4. Kriged variance:
a. This is a relative parameter and is only an indication and used in conjunction with
the other parameters.
5. Distance to sample (variogram range):
a. Measured: at least within 60% of variogram range;
b. Indicated: within variogram range;
c. Inferred: further than variogram range.
6. Lower confidence limit (blocks):
a. Measured: less than 20% from mean (80% confidence);
b. Indicated: 20%–40% from mean (80%–60% confidence);
c. Inferred: more than 40% (less than 60% confidence).
7. Kriging efficiency:
a. Measured: more than 40%;
b. Indicated: 20–40%;
c. Inferred: less than 20%.
8. Deviation from lower 90% confidence limit (data distribution within Resource area
considered for classification):
a. Measured: less than 10% deviation from mean;
b. Indicated: 10–20%;
c. Inferred: more than 20%.

The total diluted Inferred Mineral Resource for the Du Preez Leger Project at a cut off grade of 250cm.g/t
and application of a geological loss factor of 5% is 56.91Mt at a grade of 5.02g/t.
The cut-off grade of 250 cm.g/t is derived from optimistic assumed and justifiable technical and
economical conditions, under which the Resource becomes economically extractable. In Table 12 all
assumed technical and economical parameters used in deriving the 250 cm.g/t cut-off are listed. The
calculated 232 cm.g/t cut-off grade was rounded up to 250 cm.g/t.

The lower grade Leader Reef‟s average stopping width of 130 cm was used in the calculation. The minor
geological losses used in the Resource table as well as in the above calculation, was benchmarked from
the surrounding mines in the Welkom and Virginia areas. The factors used in above calculation are in line
with industry accepted standards for a Resource of this nature.
The Metal price and exchange rate calculation are based on historical trends for both parameters.
Historical gold prices are recalculated in today‟s terms and a 95% percentile is used to derive a USD gold
price. The same statistical applications are used in the calculation of the ZAR/USD exchange rate, but the
ZAR is not inflation adjusted in the case for gold.
Considering the Du Preez Leger‟s Basal Reef as a new standalone shaft and infrastructure complex, it
would be seen as a marginal economically extractable Resource. However, the Du Preez Leger Resource

area is surrounded by current mining activities which make it possible to gain access from a variety of
current infrastructure, resulting in a possible economically extractable Resource.
6.3.2 Basis of Classification of Mineral Resources
All the aspects of the Project Mineral Resource estimate are compliant with the specifications embodied
in the SAMREC Code. The Mineral Resource pertains to Au grades (g/t) at a cut-off of 250cm.g/t. All
Mineral Resource estimation carried out by Minxcon adheres to the guidelines stipulated in the SAMREC
Code.
Only Mineral Resources have been estimated for this report. All Mineral Resources have been classified as
Inferred Mineral Resources, according to the specifications of the SAMREC Code, and as such are exclusive
of Mineral Reserves.
Based on the drill hole spacing and kriging efficiencies of the estimates, and a number of other
parameters, the Mineral Resource estimate was deemed to fulfil the requirements of being an Inferred
Mineral Resource.
6.3.3 Relationship of the QP to the Issuer
Apart from having been contracted to compile this report, the QP‟s have no commercial or other
relationship with FSD. The QP who undertook the Mineral Resource estimation and compilation of this
Technical Report was Mr C J Muller (B.Sc. (Geol.) Rand Afrikaanse University, Pr. Sci. Nat. (400201/04)).
6.4 Further Work
Proposed further work on the Project will include an in-depth review of the available data by a competent
geological consulting company with the possible progression, depending upon the results of the aforesaid
review, to drilling of up to four geological boreholes as envisaged in the Prospecting works Programme.
The estimated funding requirements for exploration for 2009 and 2010 is ZAR5.185 million, and the
Company has sufficient cash resources to fund future exploration and environmental work.

The methodologies used in valuing a mineral asset differ depending on the developmental stage of the
project i.e. exploration, development and production properties.
The following three valuation approaches are internationally accepted methods of valuing mineral
projects, as illustrated in Table 13 and summarised below:-
Cost Approach: used to value early stage exploration properties and which relies on the historical and future exploration expenditure;
Market Approach: used to value exploration and development properties and which is based on the relative comparisons of similar properties for which a transaction is available in the public domain. The market approach relies on the principle of “willing buyer, willing seller” and requires that the amount obtainable from the sale of the mineral asset is determined as if in an arm‟s length transaction; and
Cash Flow Approach: used to value development and production properties and relies on the “value in use” principle and requires determination of the present value of future cash flows over the useful life of the mineral asset.

The selection of an appropriate valuation approach is dependent on the availability of information on the
property. Minxcon used the two approaches that are applied primarily to exploration properties, namely
the Market and Cost Approach.
8.1 Market Approach
The market approach relies on the principle of “willing buyer, willing seller” and requires that the amount
obtainable from the sale of the asset is determined as if in an arm‟s length transaction.
The valuation method requires comparison with relatively recent transactions of assets that have similar
characteristics to those of the asset being valued. It is generally based upon a monetary value per unit of
resource (where available) or per unit of defined mineralisation. The comparable transaction method uses
the transaction price of comparable assets to establish a value for the specific asset to be valued. The
difficulty of this approach in the mining industry is that there are no true comparables, since each asset is
unique with respect to key factors such as geology, mineralisation, costs, stage of exploration and
infrastructure. In addition, there are normally relatively few transactions for mineral assets. The
movements in the mineral price and the USD/ZAR exchange rate are also reflected in the range of values.
When transactions of mineral assets do occur, they rarely involve strictly cash, leaving the valuator the
task of converting blocks of shares, royalties or option terms into present day monetary equivalents.

Minxcon has plotted the total values of 27 historical gold transactions of properties of a similar nature,
which took place on an arm‟s length basis, in relation to their specific stage of exploration. This
methodology, when applied to exploration transactions provides guidance in terms of a range of
transaction values. The transactions used to construct the valuation curve occurred at a specific point in
time and therefore at a specific ZAR denominated gold price, which have been adjusted to current gold
prices and exchange rates. This current price adjustment was made using the average gold price and
USD/ZAR exchange rate for the three months preceding the effective date of this report, together with
the twelve month forecast, to calculate an appropriate price level. An alternative market approach is to
determine the monetary value per hectare (MVH) using relatively recent transactions of assets that have
similar characteristics to those assets being valued.
8.1.1 Price Adjustment
In order to report historic transaction in today terms and compare all transaction on the same economic
level, economic parameters (SA Rand and USD Gold Price) were determined for each historic transaction
at the time when the historic transaction took place. Historic transaction prices were then adjusted to
current day terms by determining the difference of parameters at the time of historic transactions to the
current day parameters. Parameters were calculated on a 3 month historic average preceding the
calculation date. The following gold prices and exchange rates were used in the price adjustment:-
Table 14: Economic Parameters used in the Comparative Analysis

2010 7.68 1137 280746
Average 7.59 1132 276002
This principle is used to reflect the current market expectation that is likely to drive the fair market
value.
8.1.2 Project Specific Valuation Parameters
There are specific project valuation parameters associated with each stage of project development.
Initially, risk associated with the physical characteristics of an ore body is high. As a project moves past
the feasibility stage and into detailed design, construction, start-up, and full operation, the uncertainty
associated with the risk components is reduced. Uncertainty with regard to the Mineral Resources, LoM
and grade continues until well into the operational life. Because of the inherent unknowns in geology,
some uncertainty normally persists until the end of the LoM. The Canadian Institute of Mining have derived
from industry, a valuation parameter matrix, for determining mining project risk, weighting different
criteria such as depth, mining process, geology and legal tenure. Minxcon adopted this matrix and
incorporated a single additional category, namely the Social and Environmental factor, and applied values
applicable to the South African industry as summarised in Table 15. These parameters were used to
determine a risk associated index for a project relative to that of the gold industry:-

8.2 Cost Approach
The cost approach relies on historical and/or future expenditure on the property and involves estimation
of the depreciated cost of reproducing or replacing the asset and improvements. Reproduction cost refers
to the cost at a given point in time of reproducing a replica asset; whereas replacement cost refers to the
cost of reproducing improvements of equal utility. In the case where insufficient confidence exists in the
technical parameters of the mineral asset, valuation methods rely almost entirely on the principle of
historical cost, implying that an asset‟s value is correlated to the money spent on its acquisition, plus a
multiple of expenditures. A prospectively enhancement multiplier (PEM) is a factor applied to the total
cost of exploration, the magnitude of which is determined by the level of sophistication of the exploration
for which positive exploration results have been obtained, and the prospectivity of the project (see Table
16):-

The Martix is calculated by using a formula based on the exploration phase (70% weighting) and
prospectivity rating (30% weighting) a subjective number provided by the exploration geologist to the
project multiplied by a constant which is adjusted by market sentiment. The PEM factor for gold which
currently ranges from 0 to 6.50 is then multiplied by the historical cost.

On Vermeulenskraal, the Basal Reef varies in depth from 2,100m to 2,350m to the west of the NNE-SSW trending Vermeulenskraal Fault, whilst to the east the depth varies between 1,400m and 2,000m. On the Du Preez Leger prospect, the Basal Reef is found at depths of between 1,000m and 1,200m. The Leader Reef is found at depths between 1,000m and 1,900m. On Tweepan, the Leader Reef is found to be 1,200m to 2,300m below surface. The Basal reef on Tweepan is 1,300m to 2,300m deep, whilst the B Reef is located at depths between 1,300 and 2,300m. On Rebelkop, the Leader Reef is present at depths between 1,100m and 2,000m.
Scale of Project (Resource) Medium Sized Deposit
Mining/ Process Method Underground Conventional
Infrastructure
The main road structure to and around the project are in good condition; the Du Preez Leger and Vermeulenskraal deposits can be accessed via the R34 main road through the town of Welkom. Power is supplied by ESKOM, and Sedibeng Water supplies water mainly from the Vaal River. Limited mid-term power availability may constrain development of new mining projects in the region. No current mining infrastructure exists, and no previous mining activity has taken place
Data Quality
Details of historic borehole surveys, sampling methods, drilling techniques, sample recovery, logging techniques and other sources of information were not available. No details regarding the Quality Assurance and Quality Control (“QA/QC”) for the sampling and assays were available. Minxcon did not receive any details regarding the assay laboratory and assaying procedure. As such, there can be no comment on the integrity of sampling results, but this is relied upon as being accurately recorded by current and previous Project owners for evaluation purposes.
Title/Ownership
Free State Development and Investment Corporation Limited has an approved prospecting right FS30/5/1/1/2/252PR for Gold ore and Silver ore. And will expire on 6 November 2011
Geological Complexity
The general structure of the Welkom Goldfields comprises north-south normal faults which successively displace the orebodies downwards to the west. The regional dip is 15° towards the east but variations are caused due to local structural controls. These dips are found to be almost vertical along the western margin to very flat-lying in the eastern parts of the goldfield. The largest of these faults is the De Bron Fault, which transects the Tweepan prospect. The Du Preez Leger and Vermeulenskraal prospects are to the west of this fault, whilst Rebelkop is to the east. The displacement along this fault is in the order of 1,000m. The local structural environment of the Vermeulenskraal prospect is dominated by the NNE-SSW trending normal Vermeulenskraal Fault as well as associated sub-parallel faults. They display downward displacements to the west. The Du Preez Leger prospect is located west of the Stuurmanspan Fault. This is another large normal fault which displays strong dextral lateral shifts too. On Unisel and St Helena mines large scale E-W thrusting has been noted, thus causing duplication of the ore body towards the south. The potential for the occurrence of similar structures on the Du Preez Leger Project is great.

10.2 Valuations of farms Du Preez Leger, Vermeulenskraal, Millo/Tweepan and
Rebelkop
10.2.1 Market Approach
The valuation of the project areas were based on the market approach for which Minxcon used their
valuation curve, constructed from historical transactions of properties of a similar nature. The
methodology was as follows:-
The Industry Valuation standards illustrated in Table 15 were used to estimate the project specific
risk of the areas for which resources exists. The Project principle risk criteria (Table 17) were
measured against the Industry Valuation standards in the decision making process to determine a
project valuation index;
a comparison of the project valuation indices which ranged between 28.50 (Millo/Tweepan) and
34.50 (Du Preez Leger and Vermeulenskraal) for the Inferred categories respectively, to that of
the South African gold industry (48), indicates that the project risk profile is higher, than the
South African gold industry average (Table 18);
Considering the deviation of the project valuation indices above, from the industry mean of 48,
the USD/oz industry value of USD19/oz for the Inferred Mineral Resources, was adjusted
downwards to between USD4.67/oz (Millo/Tweepan) to USD5.65/oz (Du Preez Leger and
Vermeulenskraal) which is within the boundaries set by the standard deviation for the population
of transactions analysed;
Measuring the market approach based on historic transactions above, Minxcon found that the unit
value was still above Market Related Values Per Ounce based on EV/oz as illustrated in Table 19.
The value was further adjusted to establish a value of USD2.68/oz to USD3.25/oz;
For the value calculation, the sum of the individual products of the USD/oz x Moz x ZAR7.59/USD
for the Mineral Resource of each of the respective areas were determined (Table 20); and
and compared to the South African Gold industry as shown in Figure 20.

As part of the valuation methodology, similar JSE listed gold companies were assessed and their enterprise
value (“EV”) was calculated. From these, their average market related dollar per ounce of resource value
was calculated:-
Table 19: Market Related Values Per Ounce of Mineral Resource
Company EV/oz
Gold 1 $22.07
Central Rand Gold $1.59
DRD Gold $4.19
Simmer and Jack Mines $3.26
Witsgold $1.22
Note: 1.Includes Measured, Indicated and Inferred
2.As at February 2010
Other factors taken into account include the aquisitions of the Orkney and President Steyn Mine
operations by Pamodzi Gold. Minxcon calculated that the Orkney operation was aquired at $2.78/oz and
the President Steyn Mine was aquired for $2.47/oz. It must be kept in mind that these operations are very
mature, with limited resource and substantial associated environmental liabilities, which impact
dramatically on the price received.
A sample of inferred values of typical Witwatersrand transactions which range from USD1.30/oz to
USD12.60/oz was taken from the bigger population of historical transactions. The lower 25% and upper
25% extreme values were eliminated to establish a value range for the properties within the 25th and 75th
quarter percentiles.

The Rebelkop area does not have any estimated Mineral Resources, and as the Rebelkop area has been
held by FSD since the early twentieth century, no information is available which could be used to apply
the historical cost method of valuation. Hence the Project was valued using a value per hectare.
A sample of Witwatersrand gold transactions that took place in South Africa was taken from the bigger
population of transactions and analysed. The upper value of these transaction included project with
infrastructure. Minxcon derived a R/ha value closer to the lower end of the spectrum as illustrated in

Two valuation approaches have been employed in the valuation of the Du pReez Leger Project. Minxcon‟s
extensive database provides a comprehensive and reliable benchmark for the market approach. Minxcon‟s
confidence in the market approach, leads the competent valuator to prefer the results of the market
approach versus the cost approach. However there is a strong correlation between the historical cost spend
and sequential upgrade in resources and hence provide a good range to the valuator.
A range of values was provided together with a fair value.
The upper and lower valuation range was established at between ZAR 153.988 million and ZAR 252.003 million
respectively; with a “fair” value of ZAR 240.684 million.The above valuation represents a total value for the
Du Preez Leger Project.

Following a period of high demand in 2008, the volume of total identifiable gold demand in the second
quarter of 2009 saw a significant drop with demand subsiding (World Gold Council Website, March 2009).
While the USD gold price in Q2 2009 was only 3% higher than in Q2 2008, consumers in several key markets
experienced significant price gains. Over the same period, the gold price rose 20 % in Indian rupee terms, 28
% in Turkish lira terms, 31 % in pound sterling terms, and 18 % in euro terms.
The decline in tonnage relative to Q2 2008 was attributable to weakness in jewellery and industrial demand,
offset to a considerable extent by a significant increase in investment demand. Identifiable investment
demand in Q2 totalled 222.4 t, up 46 % on year-earlier levels. Net investment demand eased significantly
relative to the highs seen during the previous three quarters when the level of uncertainty surrounding the
economy and financial sector was at extreme levels, but remained very healthy on a historical basis.
Official coin demand was up 62 % on year-earlier levels. ETF demand, at 56.7 t in Q2 2009, was robust on a
historical basis but nevertheless marked a significant reduction on the 465.1 t experienced in Q1 2009.
Jewellery demand in Q2 2009 was 22 % below year-earlier levels. The weakness was widespread, with
western countries experiencing the ongoing effects of economic hardship and non-western countries suffering
primarily from a high gold price. The exception to this trend was mainland China, where jewellery demand
rose 6 % in tonnage terms relative to year-earlier levels.
Industrial demand continued to suffer from the effects of weak economic conditions, falling 21 % relative to
year-earlier levels. The sector experienced an 18 % quarter-on-quarter gain, reflecting a significant
improvement in the other industrial and decorative and electronics components.
The USD gold price has steadily been increasing, reaching a high of USD 1,043/oz in October 2009, which is
the highest gold price ever recorded. For the 2008 year as a whole, the gold price averaged USD871.96, up 25
% from USD695.39 in 2007. The price for 2009 is expected to average USD950/oz, which is 9 % higher than
2008.
The biggest source of growth in demand for gold during the year was investment. Identifiable investment
demand reached 399.0 t in Q4 of 2008, up from 141.4 t in Q4 2007, a rise of 182 %. Demand in 2008 was 64%
higher than in 2007, equivalent to an additional inflow of USD15.2 billion. Taking into account implied
investment, which includes the more speculative side of the gold market, total investment was USD10.1
billion higher than in 2007.

For now, the outlook for gold remains buoyant. Historically drivers for gold creating market uncertainty and
prompting investors to opt for gold as alternative investment were:-
Political uncertainty;
Currency fluctuation;
Stock market uncertainty; and
High inflation and low real interest rates.

Although the gold market has never again experienced hyperinflation like was seen in the early 1980s, it still
has an impact as illustrated in the figure below, effectively lowering the real interest rate in the US.
The real rate of short term interest is currently following a downward trend and approaching negative
territory, therefore forcing investors to find alternative investments. In addition to this, the continued credit
crisis and depreciation of the USD has led to increased gold purchases as a safe haven asset and dollar hedge.
These factors underpinned the gold price reaching levels above USD1,000/oz in 2008 and 2009 with the rand
gold price trading above ZAR350,000/kg.

Term Definition
Adit An opening driven horizontally into the side of a mountain or hill for providing access to a
mineral deposit.
Acid Rock Drainage The exposure, usually as a result of mining, of sulphide-bearing minerals to air and water,
forming sulfuric acid. This acid dissolves metals such as lead, zinc, copper, arsenic,
selenium, mercury, and cadmium, into ground and surface water. Acid rock/mine
drainage can poison ground and drinking water and destroy aquatic life and habitat.
Commonly mined ore bodies that pose the risk of acid rock drainage include gold, silver,
copper, iron, zinc, and lead.
Alluvial Deposited by running water.
Amsl Above mean sea level
Achaean A period of time between 4,000Ma and 2,500Ma.
Assay Process to determine the proportions of metal in an ore.
Assay laboratory A facility in which the proportions of metal in ores or concentrates are determined using
analytical techniques.

Black Economic
Empowerment (“BEE”)
company
The following recommendations have been made to the South African government by the
Black Economic Empowerment Commission regarding the definitions of different levels of
company ownership by Black people that qualify for BEE status:
A „Black company‟ is one that is 50.1% owned and managed by Black people;
A „Black empowerment company‟ is one that is at least 25.1% owned and
managed by Black people; and
A „Black influenced company‟ is one that is 5% -25% owned and managed by
Black people.
Blank Samples that contain no mineral content that are sent to the assay laboratory for quality
control.
Block model Technique of modelling which divides the resources into mineable blocks.
Borehole
A hole drilled usually drilled from surface but also from underground, in which core of the
rock strata is cut by a diamond-impregnated bit or crown as the cutting edge. This core
can be studied and split with one half being sent for the determination of any contained
metals (called assaying).
Bulk sample Large sample which is processed through a small-scale plant and not a laboratory.
Buckshot Pyrite Pyrite that has crystallised in a cubic shape.
Carbon-In-Pulp (CIP) A common process used to extract gold from cyanide leach slurries. The process consists
of carbon granules suspended in the slurry and flowing counter-current to the process
slurry in multiple-staged agitated tanks. The process slurry, which has been leached with
cyanide prior to the CIP process, contains solubilised gold. The solubilised gold is
absorbed onto the carbon granules, which are subsequently separated from the slurry by
screening. The gold is then recovered from the carbon by electrowinning onto steel wool
cathodes or by a similar process.
Chip Sample Sample of ore chipped out of a rock face.
Clastic A sediment or rock composed chiefly of fragments derived from pre-existing rocks or
minerals.

Inferred Mineral Resource An „Inferred Mineral Resource‟ is that part of a Mineral Resource for which tonnage,
grade and mineral content can be estimated with a low level of confidence. It is inferred
from geological evidence and assumed but not verified geological and/or grade continuity.
It is based on information gathered through appropriate techniques from locations such as
outcrops, trenches, pits, workings and drill holes that may be limited or of uncertain
quality and reliability. An Inferred Mineral Resource has a lower level of confidence than
that applying to an Indicated Mineral Resource.
In situ In place, i.e. within unbroken rock.
Indicated Mineral Resource That part of a mineral resource for which tonnage, densities, shape, physical
characteristics, grade and mineral content can be estimated with a reasonable level of
confidence. It is based on exploration, sampling and testing information gathered through
appropriate techniques from locations such as outcrops, trenches, pits, workings and drill
holes. The locations are too widely or inappropriately spaced to confirm geological and/or
grade continuity but are spaced closely enough for continuity to be assumed (SAMREC
definition).
Interburden A layer of rock that lies in-between two layers of mineralised rock.

Lenticular Resembling in shape, the cross-section of a lens.
Level The workings or tunnels of an underground mine which are on the same horizontal plane.
Lithology The general compositional characteristics of sedimentary rocks.
Logging Method of obtaining a continuous record of the lithology, stratigraphy and structure of the
core obtained from a diamond-drill hole.
Lognormal Distribution A probability distribution in which the log of the random variable is normally distributed,
meaning it conforms to a bell curve.
Longitude The angular distance north or south of the earth‟s equator, measured in degrees along a
meridian, as on a map or globe.
Mean Average.
Measured Resource That part of a mineral resource for which tonnage, densities, shape, physical
characteristics, grade and mineral content can be estimated with a high level of
confidence. It is based on detailed and reliable exploration, sampling and testing
information gathered through appropriate techniques from locations such as outcrops,

Term Definition
trenches, pits, workings and drill holes. The locations are spaced closely enough to
confirm geological and grade continuity (SAMREC definition).
Metamorphic Rock Rocks that result from partial or complete recrystallization in the solid state of pre-existing
rocks under conditions of temperature and pressure.
Metaquartzite A quartzite formed by metamorphic recrystallization.
Mineable That portion of a resource for which extraction is technically and economically feasible.
Mineral Reserve The economically mineable material derived from a Measured and/or Indicated mineral
Resource. It is inclusive of diluting materials and allows for losses that may occur when
the material is mined. Appropriate assessments, which may include feasibility studies,
have been carried out, including consideration of, and modification by, realistically
assumed mining, metallurgical, economic, marketing, legal, environmental, social and
governmental factors. These assessments demonstrate at the time of reporting that
extraction is reasonably justified. Mineral Reserves are sub-divided in order of increasing
confidence into Probable Mineral Reserves and Proved Mineral Reserves (SAMREC
definition).
Mineral Resource A concentration (or occurrence) of material of economic interest in or on the earth‟s crust
in such form, quality and quantity that there are reasonable and realistic prospects for
eventual economic extraction. The location, quantity, grade, continuity and other
geological characteristics of a mineral resource are known, estimated from specific
geological evidence and knowledge, or interpreted from a well-constrained and portrayed
geological model. Mineral Resources are subdivided, in order of increasing confidence in
respect of geoscientific evidence, into Inferred, Indicated and Measured categories
(SAMREC definition).
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.
National Instrument 43 101 The Canadian Code for reporting of Mineral Resources and Ore Reserves.
Oligomictic Composed almost entirely of a single type of fragment.
Ordinary Kriging A variety of kriging which assumes that local means are not necessarily closely related to
the population mean, and which therefore uses only the samples in the local
neighborhood for the estimate. Ordinary kriging is the most commonly used method for
environmental situations.
Opencast Opencast mining is a type of surface excavation which often takes the shape of an
inverted cone; the shape of the mine opening varies with the shape of the mineral
deposit.
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.
Orebody A continuous well defined mass of material of sufficient ore content to make extraction
economically feasible.
Outcrop The area over which a particular rock unit occurs at the Earth‟s surface.
Overburden The alluvium and rock that must be removed in order to expose an ore deposit.
Palaeochannel An ancient trough or channel-like feature that was formed by river or similar stream
current action during deposition of sediment at some period of geological time.
Pay limit The breakeven grade at which the ore-body can be mined without profit or loss and is
calculated using the gold price, the working cost and recovery factors.
Payshoot High trending grade area.
Placer A sedimentary deposit containing economic quantities of valuable minerals mainly formed
in alluvial and eluvial environments.

concentrates of gold and uranium.
Refining The final stage of metal production in which final impurities are removed from the molten
metal by introducing air and fluxes. The impurities are removed as gases or slag.
Rehabilitation The process of restoring mined land to a condition approximating to a greater or lesser
degree its original state. Reclamation standards are determined by the South African
Department of Mineral and Energy Affairs and address ground and surface water, topsoil,
final slope gradients, waste handling and re-vegetation issues.
Relative Density Relative density (also known as specific gravity) is a measure of the density of a material.
It is dimensionless, equal to the density of the material divided by some reference density
(most often the density of water, but sometimes the air when comparing to gases)
Reverse Fault A dip-slip fault marked by a hanging wall that has moved upward relative to the footwall.
Riffler Ore splitter.
Royalty A payment made for a concession of commercial value.
Sampling Taking small pieces of rock at intervals along exposed mineralisation for assay (to
determine the mineral content).
SAMREC Code The South African Code for the reporting of Exploration Results, Mineral Resources and
Mineral Reserves.
Sandstone A sedimentary rock formed by the consolidation and compaction of sand and held
together by a natural cement, such as silica.
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.
Shaft Vertical or inclined passageway to access the underground mining areas.
Shale A fine grained sedimentary rock formed by the compaction of silt, clay or sand that
accumulates in deltas and on lake and ocean bottoms.
Simple Kriging A variety of kriging, which assumes that local means are relatively constant and equal to
the population mean, which is well known. The population mean is used as a factor in
each local estimate, along with the samples in the local neighborhood. This is not usually
the most appropriate method for environmental situations.
Skewness A measure of the asymmetry of the probability distribution of a real-valued random
variable.
Specific Gravity The ratio of the weight of a given volume of a substance to the weight of an equal volume
of water. (Also referred to as relative density)
