Supplement to the Integrated Annual Report 2014
INTENT
Sibanye Gold Limited’s guiding principle
is to ensure integrity and responsibility
in reporting its Mineral Resources and
Mineral Reserves, to be compliant with
public and internal regulatory codes
and to inform all stakeholders on the
status of the Group’s fundamental asset
base. Sibanye further aims to report
on information that is rated important
for disclosure to a level of detail that
ensures competency, transparency
and materiality.

commented: “It is
extremely pleasing
to see our operating
strategy taking
effect. Significant
improvements in the
quality of mining
and cost control at
our operations in the

SECTION 1 INTRODUCTION
INTRODUCTION
Sibanye Gold Limited (“Sibanye Gold”, “Sibanye”, or “the
Group”) is an unhedged producer of gold, with attributable,
annualised production of ~1.6Moz of gold from four mining
operations and a surface retreatment operation located in South
Africa. The Group is also growing its uranium portfolio, with
planned production of more than 250,000lbs in 2015.
Sibanye’s portfolio of operating assets has changed materially
in 2014, with the acquisition of the Cooke Operations from
Gold One International Limited (“Gold One”). Sibanye now
also holds a comprehensive portfolio of brownfields projects
at its operating mines, as well as greenfields projects with the
acquisition of Witwatersrand Consolidated Gold Resources
Limited (“Wits Gold”).
The geology and evaluation models of the Group’s operational
assets have been updated to reflect the latest available data,
and have proved to be stable with only minor variances in
the Mineral Resources and Mineral Reserves year-on-year.
Operational models are coupled with an integrated and
holistic mine design and schedule plan based on actual and
expected performance levels. During 2014, the geology and
evaluation models of the projects acquired from Wits Gold
have been revised and brought in line with Sibanye’s protocols
and procedures. The newly acquired Wits Gold Projects have
seen larger changes in the Mineral Resources and Mineral
Reserves year-on-year due to the more conservative protocols
that Sibanye applies to ensure compliance with the relevant
reporting codes.
At 31 December 2014, Sibanye had total managed Mineral
Resources, inclusive of projects, of 103.9 (128.7) million
ounces (Moz) of gold and 227.4 (282.3) million pounds (Mlb)
of uranium. Managed Mineral Resources (excluding projects)
were 78.7 (80.2)Moz gold and 93.4 (76.5)Mlb uranium net of
depletion. The corresponding total managed gold and uranium
Mineral Reserves inclusive of projects were 28.4 (32.7)Moz net
of 1.7Moz depletion, and 102.5 (102.8)Mlb, net of 0.2Mlb
depletion respectively.
Please note that the Mineral Resources and Mineral Reserves
stated in this supplement include the Sibanye 2014 acquisitions
as declared at 31 December 2013. All valued 31 December
2014 comparisons/reconciliations are therefore against the 31
December 2013 numbers, unless otherwise stated.
IMPORTANT NOTICES
1. The United States Securities and Exchange Commission
(SEC) permits mining companies, in their filings with
the SEC, to disclose only those mineral deposits that a
company can economically and legally extract or produce
from. Certain terms are used in this report, such as
“Mineral Resources”, that the SEC guidelines strictly
prohibit companies from including in filings. US investors
are urged to consider closely the disclosure in the Form
20-F submission.
2. Mineral Resources and Mineral Reserves reported are
managed by Sibanye unless otherwise stated, and Mineral
Resources are inclusive of Mineral Reserves.
3. Rounding-off of figures in this report may result in minor
computational discrepancies. Where this occurs it is not
deemed significant.
4. The 31 December 2014 Mineral Resources and Mineral
Reserves are net of depletion.

• Stable geology and estimation models at the historic Sibanye operations, with
planned production levels based on current and expected performance levels;
• Acquisition of Wits Gold, which included the Burnstone Project and related assets
(April 2014);
• Acquisition of the Cooke operations from Gold One (May 2014);
• The incorporation of the Wits Gold and Cooke assets resulted in a significant increase
in the C2014 gold and uranium Mineral Reserves and production, and extended the
C2014 LoM production profile of Sibanye:
• Mineral Reserves increased by 44% to 28.425Moz
(19.733Moz pre acquisitions);
• Uranium Mineral Reserves increased by 137% to 102.480Mlb (43.155Mlb pre
acquisitions);
• Cooke production has increased Sibanye’s gold production for 2014 by 12% to
1.59Moz; and
• Sibanye realised it’s first uranium shipment from the Cooke operations.
• Year-on-year the post production depleted Mineral Resources of the mature
underground operations Kloof, Driefontein, Beatrix and Cooke (KDBC) remained
virtually unchanged at 78.124Moz (79.398Moz at 31 December 2013);
• Pre-feasibility studies of the Driefontein and Kloof Drop-down Projects were
approved, and realised an additional 1.657Moz gold Mineral Reserves;
• Ongoing assessment of Secondary Reefs and White Areas at Kloof and Driefontein,
has resulted in the inclusion of 0.978Moz gold Mineral Reserves;
• The Burnstone geology model has been de-risked, and the definitive feasibility
study (DFS) is in progress. The project presents an attractive opportunity, from
both a strategic and operational perspective; and
• A phased development approach has been adopted for the West Rand Tailings
Retreatment Project (WRTRP), specifically considering how to leverage available
surface infrastructure. The WRTRP is on schedule with a DFS due for completion
during Q1 2015.

REPORTING CODE
Sibanye reports its Mineral Resources and
Mineral Reserves in accordance with the South
African Code for the Reporting of Exploration
Results, Mineral Resources and Mineral Reserves
(SAMREC Code – 2007 edition and amended
July 2009), South African Code for the reporting
of Mineral Asset Valuation (SAMVAL Code – 2008
edition amended July 2009) and other relevant
international codes such as the United States
Securities and Exchange Commission (SEC)
Industry Guide 7 for the reporting of Mineral
Reserves. The assessment and reporting criteria,
as outlined in the SAMREC Code, have been
used in the preparation of internal Competent
Persons Reports for the Mineral Resources and
Mineral Reserves for each of the operations and
projects from which the numbers stated in this
supplement are drawn.
The process followed in producing the
declaration is in alignment with the guiding
principles of the Sarbanes-Oxley Act of 2002
(SOX). Covering the entire Group’s Mineral
Resource Management (MRM) function,
SOX audits run in parallel with external Mineral
Resource and Mineral Reserve audits and
strengthens the internal control process, leading
to world class corporate governance practices.
The Sibanye operations operate under new
order mining rights in terms of the Minerals
and Petroleum Resources Development of Act
of 2002 (Act No. 28, of 2002) (MPRDA). All
required operating permits have been obtained,
and are in good standing.
The gold Mineral Reserve price used for
estimation is in accordance with the SEC
guidelines and approximate the three-year
trailing average price, as calculated on a monthly
basis based on the London afternoon gold price
fix. The Mineral Resource gold price used has
a premium of ~10% over the R/kg Mineral
Reserve gold price, representing upside potential
leverage to the spot price of gold. The uranium
Mineral Reserve price used for estimation
is based on the long-term outlook price for
uranium and is ~1% lower in South African
rand terms than the price used for the
31 December 2013 declaration.

The Group has proven expertise in exploration, resource modelling, mine planning and reconciliation
methodologies for shallow and deep to ultra-deep underground mining operations. It constantly reviews
and considers the application of international leading practices in Mineral Resource Management at all its
operations and projects.
ESTIMATION PRINCIPLES
• Mineral Resource tonnages and grades are
estimated in situ over a minimum mining width,
and include mineralisation below the selected
cut-off grade to ensure that the Mineral
Resources comprise practical mining blocks
of adequate size and continuity. Measured
and Indicated Mineral Resources are reported
inclusive of those Mineral Resources modified
to produce Mineral Reserves;
• Mineral Reserves, are that portion of the
Mineral Resources, which technical and
economic studies have demonstrated can
justify extraction at the time of disclosure (to a
minimum pre-feasibility study level). Estimates
of tonnages and grades quoted as Mineral
Reserves include allowances for all mining
dilution, all other mining factors (modifying
06
Sibanye Gold Mineral Resources and Mineral Reserves 2014
factors) and consequently are reported as net
tons and grades delivered to the mill;
• Estimation and modelling processes protocol
includes the following:
• The Mineral Resource is divided into
domains based on the geology models.
The domains may be further sub-divided
in order to ensure homogeneity, which
are used as the basis for the geostatistical
estimation. Detailed exploratory data
analyses, including
sample verification, histogram and
cumulative frequency plots for
distributional analysis, additive
constant estimates, outlier checks,
trend analyses, and de-clustering are
carried out on individual domains;
SECTION 1 CORPORATE GOVERNANCE
• The main interpolation methodology
utilised is ordinary and simple Kriging
of various block sizes including macro
Kriging. Detailed checks are carried out
on the Kriged estimates by compiling
Kriging efficiencies and Kriging slopes
of regression on an individual Kriged
block basis;
• Variography studies are carried out on
point and regularised data. Relative
and traditional variograms are used
for Kriging purposes. The Resource
block widths are projections of the
stoping width (“SW”), and are estimated
using a study of the historical CW/SW
relationship derived from the stope
sampling records, with the exception of
Cooke where a planned mining cut is
applied; and
• Historical statistics are used as the
basis of the unavoidable un-pay mined
included in the Mineral Resource. The
historical percentage un-pay is then
added to the portion of blocks above
the pay limit, while ensuring there are
sufficient Mineral Resources available.
• All operations have documented the
guidelines and modifying factors that
underpin the Life of Mine (LoM) plans,
which are supported by mine designs
and schedules;
• A detailed one year operating and capital
cost budget is produced and, where
appropriate, extended for the LoM
production schedule. The operational plan
is prepared on a monthly basis, using
zero-based costing. Of critical importance
is the utilisation of historically achieved
data to estimate planned productivity and
operating cost;
• For the 2014 declaration only Measured
and Indicated Mineral Resources have
been included in any pre-feasibility or
feasibility study. No Inferred Mineral
Resources has been included in any of the
above-mentioned studies.
• Caution should be exercised when
interpreting the grade tonnage curves
presented. The ability to high-grade
(selectively mine) the deposits may be
precluded by the deposit geometry,
mining method and the need for practical
development of the ore body;
• Gold and uranium are reported separately,
therefore no gold equivalents are stated to
avoid potential anomalies because of yearon-year metal price differentials;
• Mineral Reserves are estimated using a
total cost (excluding capital) pay limit/cutoff grade at a margin, historic cost levels
and mining efficiencies at each operation.
The conversion ratio from Mineral
Resources to Mineral Reserves is further
affected by the following key factors:
• Mining quality factors, such as Mine Call
Factor (MCF) and dilution.
• Power and utility escalation has been
factored into all financial models;
• All financial models are based on
promulgated tax laws as at
31 December 2014;
• The Sibanye operations are entitled to mine
all declared material located within their
Mining Rights and all necessary statutory
mining authorisations and permits are
in place or have reasonable expectation
of being granted. However, the duration
taken for final approval may impact the
production schedules;
• Uranium is not the commodity of primary
interest and is only exploited in areas
where the primary commodity (in this case
gold) is of economic concern, hence the
uranium Mineral Resources are a subset of
the gold Mineral Resources and only where
the grades are sufficiently high to warrant
the extraction thereof; and
• All tabulated numbers represent Sibanye’s
total managed Mineral Resources and
Mineral Reserves unless otherwise
stated and all references to tons are
metric units.
• Mining constraints applied to the
extraction, based on the geometry of
the geological structures as presently
interpreted; and

CODE OF PRACTICE
DISCOVERY AND EXPLORATION
The discovery of gold in quartz-pebble
conglomerates on the farm Langlaagte near
Johannesburg in March 1886 focused the
world’s attention on a sequence of rocks that was
to become the greatest source of gold on earth.
Initial activities were confined to outcrops but
prospectors quickly realised, through geological
synthesis and technological innovation, the
extension of these rocks under younger cover
rocks. Diamond drilling was used as early as
1889 and together with geophysical methods led
to the discovery of the Carletonville Goldfields
(West Wits Line) in the 1930s and the Welkom
Goldfields in 1946. After the initial discoveries,
extensive exploration, using a combination of
surface exploration drilling and geophysical
methods, led to the discovery of the Sibanye
operations (a detail history per operation is
captured on the back of the shareholders plan of
each operation which is attached as tear-outs at
the end of this document).
Exploration drilling during the discovery period
of the Sibanye operations and projects was
executed from surface, on irregular grids
of 500 to 2,000 metres depending on the
exploration strategy, depth of the mineralised
horizons and geological uncertainty. Once in
operation with underground access established,
infill grade control drilling is conducted from
access haulages and cross-cuts to provide a
30 to 100 metre grid depending on geological
requirements, evaluation and safety.
In the interests of proactive geological
understanding, Sibanye’s exploration strategy
includes the following:
i.Initial (discovery and secondary reefs) and
infill (resource definition enhancement)
exploration drilling (current and new projects);
ii.timeous prospect development;
iii.reducing localised uncertainty inherent to the
deposit at current operations;
iv.grade control drilling on current operations; and
v.exploratory visits to previously mined areas to
confirm structure and facies.

A continuous Mineral Resource definition
programme is in place at each operation
and project to facilitate better planning and
optimisation with appropriate lead time, and to
ensure robust geological and evaluation models
that will underpin the resource definition of the
of the various reefs mined. The programme
will confirm the ore body potential in all areas
of operation, including secondary reefs and
minerals such as uranium.
Sibanye Gold Mineral Resources and Mineral Reserves 2014
QUALITY ASSURANCE AND QUALITY CONTROL
Sibanye upholds rigorous Quality Assurance and
Quality Control (QA/QC) procedures on all of its
exploration drilling and sampling programmes
(including underground chip sampling). It
follows industry best practice in data acquisition,
ensuring data reliability and utilises analytical
laboratories which are frequently reviewed,
both internally and externally. Analytical QA/
QC is maintained and enforced through the
submission of blanks, certified reference
material, duplicate samples, umpire laboratory
checks and frequent density measurements.
Laboratories currently used by Sibanye and their
related SANAS facility accreditation numbers are
as follow:
• Sibanye Analytical Laboratory (Driefontein)
Reg. no 2002/031431/07 (SANAS Facility
Accreditation No: T0379);
• SGS South Africa (Pty) Ltd (Booysens)
Reg. no. 1949/032643/07 (SANAS Facility
Accreditation No: T0169);
• Performance Laboratory (Randfontein)
Reg. no. 1996/01447/07 (now part of SGS)
(SANAS Facility Accreditation No: T0265);
• Performance Laboratory (Allanridge) Reg.
no. 1996/01447/07 (now part of SGS)
(SANAS Facility Accreditation No: T0385); and
• The process to achieve SANAS accreditation
for the Beatrix Analytical Laboratory (Reg. no
2002/031431/07) has commenced in 2014.
The QA/QC of borehole data is handled through
the Sibanye Borehole Management System.
This software is developed by Century Systems
and Datamine and comprises “DH Logger”
for borehole log inputs, and the “Fusion”
database. The underground gold assay values
are kept in digital format in Sibanye Integrated
Resource and Reserve Information System
(“IRRIS”) under the MineRP Sampling System.
The database integrity is maintained by the
initial authorisation of all sampling data. Final
submission of each sample into the IRRIS
database is only completed following
a series of checks and approvals in the
Borehole Management System or the MineRP
Sampling System.
The long mining history and the quantity and
quality of the data upon which the Mineral
Resource and Mineral Reserve estimates are
based, are sufficient to support the estimates as
derived. The Borehole Management and IRRIS
Systems provide an auditable trail from sampling
through to the Mineral Resource and Mineral
Reserve estimates.
SECTION 1 CORPORATE GOVERNANCE
MINERAL RESOURCE AND
MINERAL RESERVE EVALUATION
The Mineral Resource and Mineral Reserve
evaluation is based on systematic and
sustainable mineral reporting practices
compliant with the SAMREC Code. Data from
exploration drilling, underground mapping and
prospect drilling is used to generate or update
the geological models, which in turn are used
as the basis of each declaration. At current
operations, on-going grid-based sampling of all
development and stoping provides additional
data which is incorporated into a detailed
evaluation model (discussed in detail under
Estimation Principles).
Mineral Resource categories are based upon
the quantity, distribution and quality of data
available and confidence attached to the data,
i.e. drilling, mapping (geological understanding
and interpretation), sampling, analytical data and
geostatistical relationships. Drilling, sampling and
analytical QA/QC also plays a major part in the
data confidence applied for the final classification.
Peer reviews, together with internal and external
audits, ensure consistency and compliance with
regulatory codes. Mineral Resources and Mineral
Reserves are reported within each individual
mining or prospecting right and are adjusted to
show the separation between above (AI) and
below (BI) current shaft infrastructure.
Sibanye Mineral Resources and Mineral
Reserves are reviewed and audited on an ongoing basis by internal competent persons, with
formal audits conducted as follows:
• On-going technical review of all the operations
and projects; and
• Annual executive review of all operations
and projects.
In addition to the internal audits, the December
2014 statement were reviewed and audited
by external auditors CJM Consulting (Pty)
Ltd (Mineral Resources) and by Royal
HaskoningDHV (Mineral Reserves), and was
found to comply with the relevant codes. No
material shortcomings were identified in any
of the processes by which the Sibanye Mineral
Resources and Mineral Reserves were compiled
and evaluated.
The December 2014 declaration reports
on Mineral Resource and Mineral Reserve
information that is rated important for disclosure
and reflects a level of detail required for
competency, transparency and materiality
in reporting.
COMPETENT PERSONS AND DECLARATION CONSENT
The Competent Persons designated in terms of
SAMREC that take responsibility for the reporting

Al: Above Infrastructure; Bl: Below Infrastructure. Mineral Resources are inclusive of Mineral Reserves. All tons (t) relate to metric units. Rounding-off of figures may result in minor computational
discrepancies, where this happens it is not deemed significant.
Cut-off grades have been calculated in accordance with the SEC Guidelines and approximate the historic two to three year average commodity prices. Mineral Resources were declared at a premium
of 10% over the Mineral Reserve metal price. Gold Mineral Resources were determined at R460,000/kg and the Gold Mineral Reserves at R420,000/kg.

Sibanye Gold Mineral Resources and Mineral Reserves 2014
SECTION 1 GROUP MINERAL RESOURCE AND MINERAL RESERVE DEPLETION AND GROWTH
GROUP MINERAL RESOURCE AND MINERAL RESERVE DEPLETION AND GROWTH
Key aspects that impacted the Sibanye
31 December 2014 Mineral Resource and Mineral
Reserve Statement are summarised below:
• Economically extractable gold Mineral
Reserves from current operations have
increased by 12% to 19.878Moz (net of
1.723Moz production depleted from mining in
2014). The gold Mineral Resources from the
current operations have decreased by 2% to
78.657Moz;
• Underground gold Mineral Reserves increased
by 2.308Moz, net of production depletion,
following the successful conclusion of prefeasibility studies on various organic growth
projects at the operations;
• The 12% increase in gold Mineral Reserves
is primarily a result of an additional
1.657Moz of gold Mineral Reserves
being declared at the Driefontein 5 and
Kloof 4 shafts, following the completion
of pre-feasibility studies (PFS) on below
infrastructure “Drop-down Projects”.
Development of these brownfield projects
will substantially enhance the life of these
key operations. Definitive feasibility studies
(DFS) for these projects are in progress and
will be completed during 2015; and
• An additional 0.978Moz from so-called
“secondary reefs” and white areas were
also declared. Studies to bring more of
these potential Mineral Resources to
account are on-going.
• A maiden gold Mineral Resource of 54.1Mt
at an average grade of 5.1g/t (8.890Moz) at
the recently acquired Burnstone Project has
been declared;
• The geological model at the Burnstone
Project has been significantly revised
after extensive re-logging of existing
surface boreholes, combined with
additional information from infill drilling
and a thorough review of all available
data. The revised model is consistent with
the characteristics of similar ore bodies
in the East Rand Basin, affording greater
confidence in the interpretation and
underpinning the gold Mineral
Resource estimate.
• Mineral Resources and Mineral Reserves
at the Company’s West Rand Tailings
Retreatment Project (“WRTRP”) remain
largely unchanged year-on-year. This project
is currently the subject of a DFS that will be
completed during the March 2015 quarter;
• Since acquiring Wits Gold in April 2014,
Sibanye has reviewed the geology and/or
LoM models of the De-Bron Merriespruit,
Bloemhoek, Hakkies and Robijn, as well
as the Beisa North and South Projects in
the Southern Free State Goldfields and
re-estimated the Mineral Resources in
accordance with the Group’s protocols
and procedures;
• At the De-Bron Merriespruit Project, the
application of Sibanye’s resource estimation
protocols and procedures resulted in
gold Mineral Resources declining from
10.900Moz to 4.022Moz. Gold Mineral
Reserves also declined from 3.100Moz
to 2.088Moz. The gold Mineral Reserves
for the De-Bron Merriespruit Project
were derived from the original feasibility
study previously conducted by Royal
HaskoningDHV in 2013. During 2015,
Sibanye intends undertaking a full review of
this feasibility study with a view to optimise
any potential synergies with the Beatrix
Operations; and
QUALITY MINERAL RESERVES
ARE THE FOUNDATION OF WEALTH
AND FUTURE SECURITY OF
SIBANYE, AND MINERAL RESERVE
SUSTAINABILITY IS RELIANT ON
A SOUND BROWNFIELDS AND
GROWTH PROJECT STREAM.
• New geological models, incorporating
borehole data from both Wits Gold and
Beatrix has resulted in a complete revision
of the geological model for the Bloemhoek
Project. This, together with the application of
Sibanye’s Mineral Resource
estimation protocols and higher cut-off
grades, has resulted in the gold Mineral
Resources decreasing from 14.000Moz
to 4.297Moz. The Group is reviewing the
economic viability of accessing part of the
Bloemhoek Mineral Resource by using
the existing underground infrastructure of
Beatrix 3 Shaft. No gold Mineral Reserves
will be declared on the Bloemhoek Project
until these studies have been completed.
• Uranium production from the Cooke operation
continued uninterrupted from June 2014
under Sibanye management. The additional
information derived during mining, combined
with revised uranium Mineral Resource
estimates resulted in uranium Mineral
Resources and Mineral Reserves increasing
at the Cooke 1, 2 and 3 operations. At Cooke
4, uranium Mineral Reserves were negatively
impacted due to reduced ore reserve
development during the Section 189 process.
This will be reconsidered subject to on-going
operational profitability; and
• The uranium Mineral Resources contained at
Beatrix’s Beisa Project increased marginally
to 26.968Mlb (25.658Mlb). The application
of Sibanye’s Mineral Resource estimation and
declaration protocols resulted in a decrease
in the uranium Mineral Resource at the Beisa
North Project from 47.840Mlb to 35.373Mlb.

GOLD MINERAL RESERVE SENSITIVITY
The sensitivity of Mineral Reserve ounces at all the operations is shown in the accompanying chart at
-10%, -5%, Base (R420 00), +5% and +10%, and are derived from a factored application of the base
case scheduled Mineral Reserve, reflecting the impact of a changing gold price on the prevailing cut-offs.
The Mineral Reserve sensitivities are not based on detailed depletion schedules and should be
considered on a relative and indicative basis only. WRTRP included across the range at the base
declaration price and growth projects (Beisa North, Beatrix Beisa, Bloemhoek and Burnstone) brought
in at 10% increase in Mineral Reserve price.

OVERVIEW
Sibanye’s portfolio of operating
assets includes the Beatrix,
Driefontein and Kloof
Operations and the Cooke
Operation acquired from
Gold One in May 2014. The
Cooke Operation consists of
the Cooke 1, 2 & 3 Shafts
underground operation (Cooke
123), the Cooke 4 or Ezulwini
Shaft underground operation
(Cooke 4) and the Randfontein
Surface Operation that reclaims
sand and slime tailings in the
Randfontein area (RSO).
Gold Mineral Reserves
at the Group operations
increased by 2.097Moz or
12% to 19.878Moz, from
the 17.780Moz declared at
31 December 2013, despite
a production depletion of
1.723Moz in 2014. The historic
Kloof, Driefontein and Beatrix
Operations produced 45,127kg
(1.45Moz) of gold during the
year, which was just over
1% higher than in 2013. The
Cooke Operation contributed
4,305kg (138,400 ounces)
during the seven months
of incorporation in Sibanye.
Uranium production from the
Cooke Operation continued
uninterrupted from May 2014,
resulting in a stockpile of
approximately 180,000
pounds uranium at year-end.

GEOLOGICAL SETTING AND MINERALISATION
Gold was first discovered near Johannesburg
in March 1886 with the recognition of gold
in quartz-pebble conglomerates (traditionally
termed “reefs”) contained in a ~6,000 metre
thick succession of principally argillaceous and
arenaceous sediments in a sedimentary basin
called the Witwatersrand Basin.
The Basin is geographically located in the central
north to north-eastern part of South Africa and
extends from Johannesburg in the north to some
40 kilometres south of Welkom, and covers an
area of approximately 70,000 square kilometres.
More than 150 mines have operated in the
Basin since gold was first discovered, producing
primarily gold, but since the early 1950s,
uranium as well. Together, these mines have
produced approximately 150,000 tons of uranium
and more than 46,000 tons of gold, amounting
to no less than 39% of all gold ever mined in the
world (in excess of 4.5 billion tons of ore, with
an average grade of 9 g/t – after Handley, 1990,
1995). The Sibanye operations are hosted in this
unique and renowned basin, which remains the
world’s largest gold producing region.
The Sibanye operations and projects are
located in three geographical regions of the
Witwatersrand Basin, namely the Far West
Rand Goldfield (West Rand and West Wits Line),
some 30 to 80 kilometres west to southwest of
Johannesburg, the Free State Goldfield, 240
kilometres southwest of Johannesburg and
the South Rand Goldfield, some 75 kilometres
south-east of Johannesburg. The operations of
the Far West Rand Goldfield are the Driefontein,
Kloof and Cooke Operations between the
towns of Carletonville and Randfontein, in the
Free State Goldfield, the Beatrix Operation
near Virginia and in the South Rand Goldfield,
the Burnstone Project near Balfour some 30
kilometres east of Heidelberg.
The basin is overlain by outliers of Karoo
Supergroup shales and sandstones at the
surface, followed by Pretoria Group sediments
and the Chuniespoort Group dolomites.
The dolomite overlies the Klipriviersberg
Group volcanic rocks, which in turn cap the
Ventersdorp Contact Reef (VCR) and sediments
of the Central Rand Group that host the other
gold bearing reefs exploited.
Image
Cooke A1 Reef
24
The reefs, which are generally less than
2 metres thick, are widely considered to
represent extensive fluvial deposits into a yoked
basin. The gold is mainly of detrital origin,
deposited syngenetically with the conglomerates
Sibanye Gold Mineral Resources and Mineral Reserves 2014
interrelated with sedimentary features such as
unconformities and fluvial channels. Deposition
took place along the interface between a fluvial
system that brought the sediments and heavy
minerals from an elevated source-area, and
a lacustrine littoral system that reworked the
material and redistributed the finer sediments
along the shoreline of an intra-cratonic lake or
shallow inland sea.
Although the gold generally occurs in native form
and is usually associated with pyrite, carbon
and uranium, most of it has been subsequently
modified and remobilised during secondary
hydrothermalism. This has informed the use
of the Modified Palaeo-placer Model, which
emphasises a control on the occurrence of ore
minerals by placer-forming mechanisms, while
accepting some modification by metamorphism.
It is the generally accepted model for the origin
of gold and uranium mineralisation of the
Witwatersrand Basin.
For several decades, models using
sedimentological principles have been
successfully used to define gold distribution
on mine properties. The most fundamental
control to the gold distribution remains the
association with quartz-pebble conglomerates
on intra-basinal unconformities. The reefs are
continuous, as a consequence of the regional
nature of the erosional surfaces. Bedrock
(footwall) controls govern the distribution
of many of the reefs. Consequently, the
identification and modelling of erosional/
sedimentary features is the key to in situ
resource estimation.
As early as 1923, the presence of uranium was
noted in the Witwatersrand conglomerates. The
changing economics regarding uranium near
the end of World War II prompted a second look
at the Witwatersrand conglomerates as a source
of supply. It was found that on average the
conglomerates contain about 0.03% uranium
and as a by-product of gold relatively low
uranium grades can be recovered.
Notwithstanding different opinions as to the
origin of the uranium in the conglomerates
of the Witwatersrand Basin, most theories
accept localisation of both gold and uranium
as a function of sedimentary textures. Metal
concentrations are directly related to the
conglomerates and exploration programmes and
eventual evaluation of uranium according to a
placer philosophy, prove to be highly successful.

OVERVIEW
Beatrix is a large, established, shallow to deep
level gold mine, operating under a Mining Right
[DMR Ref. FS30/5/1/2/2(81)MR] valid from
07 February 2007 to 06 February 2019, covering
a total area of 16,835 hectares. The Beatrix
Mining Right was amended during the year,
with the exchange of ground along the common
boundary between Beatrix and Joel [ARMgold/
Harmony Freegold Joint Venture Company
(Proprietary) Limited]. The current LoM plan of
Beatrix continues beyond 2019, however, Beatrix
in the near future, intends to apply for a Mining
Right renewal in terms of Section 24 of the
Mineral and Petroleum Resources Development
Act, 2002 (Act No. 28 of 2002).
Geographically Beatrix is located in the southern
portion of the Free State Goldfields of the
Witwatersrand Basin near the towns of Welkom
0
5km
Gauss Conform Projection

and Virginia, approximately 240km southwest of
Johannesburg in the Free State Province of South
Africa. The topography of the area is relatively
flat, situated in a semi-arid region. Pre-mining
conditions were generally that of farmlands, where
the natural vegetation had been removed and
replaced with cultivated crops.
The current mine infrastructure consists of
three producing shaft complexes that mine
open ground and pillars (white areas), with the
deepest operating level some 2,055 metres
below surface (22 Level at 4 Shaft), and two
gold processing plants. The principal mining
takes place on the Beatrix Reef (BXR and local
facies variations thereof, which includes the VS5
and Aandenk Reefs), which constitutes almost
69% of the Mineral Reserve ounces and the
Kalkoenkrans Reef (KKR) 29%. The remaining
2% is derived from surface sources.

SECTION 2 THE BEATRIX OPERATION
Competent Person(s)
The Competent Persons per mining unit (MU) designated in terms of SAMREC, that take responsibility for the
consolidation, reporting and overall compliance of Beatrix’s 2014 Mineral Resources and Mineral Reserves are
the respective Mineral Resource Managers:
MU1: North Section (3 Shaft)
Mr SG Becker [BEng. Mining Engineering, Mine Manager’s Certificate] is a registered ECSA member
(No. H875564) and has 32 years’ experience;
MU2: South Section (1 Shaft)
Mr C Opperman [ND Mine Surveying, LDP (UNISA), MAP] is a registered SAIMM member (No. 706906) and
has 33 years’ experience; and
MU3: West Section (4 Shaft)
Mr D Oosthuizen [MSCC] is a registered SAIMM member (No. 706910) and has 26 years’ experience.
Internal technical reviews have been conducted by the Competent Persons who gave their consent for the
disclosure of the C2015 Mineral Resource and Mineral Reserve Statement. All have sufficient experience relative
to the type and style of mineral deposit under consideration and are full-time employees of Sibanye.
REVIEW
Gold Mineral Resources at Beatrix increased
by approximately 0.548Moz (6%) to 9.859Moz
(inclusive of Beisa at 1.194Moz). Gold Mineral
Reserves increased by 1% to 3.669Moz, mainly
due to an increase in value at North and West
Sections, and the inclusion of additional white
areas and tail-end management at West Section.
Structural changes in the area east of the North
Section (Vlakpan) and in the syncline area at
West Section, negatively impacted on the total
Mineral Resources declared by 0.318Moz.
Beisa mine optimisation studies are currently
in progress and consequently only a gold and
uranium Mineral Resource has been declared
for the Beisa Reef (above current infrastructure
and confined to the Beatrix Mining Right). The
uranium Mineral Resource declared for the
Beisa Reef is marginally higher than last year
at 26.968Mlb (C2013 at 25.658Mlb) following
additional Mineral Resource conversion drilling.
Mineral Reserve development will remain a key
performance indicator for C2015. The following
table details the development advanced for the
last 12 months to December 2014 (C2012 and
C2013 numbers added for comparison). A total
of 19.7km was developed in C2014 of which
6.1km was on-reef.
Beatrix concluded a pre-feasibility study on
the re-opening of the old Beisa Mine at 4 Shaft
(West Section), with the intent of mining and
processing the uraniferous and auriferous
Beisa Reef for gold and uranium respectively.

KEY DEVELOPMENTS AND BROWNFIELD PROJECTS
(ON-MINE)
• Beatrix is accessing the Vlakpan area over
the LoM, as part of the strategy of optimising
the Mineral Resource to Mineral Reserve
conversion. The Vlakpan Project comprises
ground between 16 and 22 Level to the west
of the Beatrix North and South Sections.
Access to the area is by means of twin
haulages, and a winze from South Section.
A detailed mine design and schedule, based
on the current geological interpretation,
evaluation and economic parameters, coupled
with a detailed engineering layout, cost and
cash flow models, have been completed for
the Project, and as a consequence has been
incorporated into the current LoM plan;
• The Operation has concluded a PFS on the
re-opening of the old Beisa Mine at 4 Shaft.
The intent is to advance this study to a DFS
during 2015; and
• Further studies are required to assess the
potential below current infrastructure at 3 Shaft
to access part of the Bloemhoek area to the
north of 3 Shaft (outside the current Beatrix
Mining Right).

Geographically Cooke is located along the
western limb of the West Rand Goldfields of
the Witwatersrand Basin near the towns of
Randfontein and Westonaria, approximately
30 kilometres west of Johannesburg in the
Gauteng province of South Africa. The site is
accessed via the local R28 highway between
Randfontein and Westonaria or via the N12
national road between Johannesburg
and Potchefstroom.

The surface topography over the area is
characterised by moderately undulating
plains, with savannah grassland being
the natural vegetation in the area. Premining conditions were generally that of
farmlands, which is now largely built-up and
industrialised. The area is characterised
by a mild climate, with warm to hot, moist
summers and cool dry winters.
Cooke 123 in its current form dates
from 22 April 2010 with the cession
of Randfontein Estate Limited to Rand
Uranium Pty Ltd (inclusive of RSO) and
Cooke 4 dates from 20 April 2010 with the
cession of Simmer and Jack Mines Ltd to
Ezulwini Mining Company (Pty) Limited
(Ezulwini). In-turn Gold One acquired
Rand Uranium and Ezulwini in August
2012 followed by the transaction between
Sibanye and Gold One when Sibanye
acquired Rand Uranium Pty Ltd and
Ezulwini in May 2014.
The current mine infrastructure consists
of four producing shaft complexes that
mine open ground and pillars (white
areas), with the deepest operating level some
1,634 metres below surface (58 level at
Cooke 4 SV Shaft). The production from the
four Cooke shafts is being hoisted to surface
individually. Underground material from
Cooke 123 is processed at the Doornkop
Plant, operated by Harmony Gold Mining
Company Ltd, on a toll treatment basis and
from Cooke 4, at the Ezulwini gold-uranium
Plant situated near the Cooke 4 Shaft.
Ore from the uranium section at Cooke 3
is hoisted separately and trucked to the
Ezulwini gold-uranium Plant for treatment.
The principal mining takes place on the
UE1A Reef, which constitutes 48% of the
underground Mineral Reserve ounces, the
Upper Elsburg Reefs (25%), the Middle
Elsburg Reefs (12%), various secondary
reefs of the Elsburg and Kimberley
Formations (4%) and the VCR (11%).

Shallow to intermediate-depth gold mine exploiting the UE1A Reef, various secondary reefs of the Elsburg and
Kimberley Conglomerate Formations and the Ventersdorp Contact Reef (VCR).
Licence status and holdings
The Cooke Operation has a new order mining right in terms of the Minerals and Petroleum Resources
Development Act, 2002 (Act No. 28 of 2002), separated into three individual rights with granted durations
as follow:
1. Cooke 123 from 18 December 2007 to 17 December 2037 in respect of a mining area totalling
7,875 hectares;
2. Cooke 4 from 20 November 2006 to 19 November 2036 covering a total area of 3,718 hectares; and
3. RSO from 07 May 2009 to 06 May 2039 covering a total area of 3,130 hectares.
All required operating permits have been obtained, and are in good standing. Cooke 4 also holds a prospecting
right [DMR Ref. GP(10151)PR] in respect of an area (6,843 ha) contiguous to the east of Cooke 123 and Cooke 4,
which is valid until October 2016. Cooke 4 is in the process of finalising a Section 102 application to amend
Cooke 4’ mining right through the inclusion of the prospecting right (Zuurbekom).
Infrastructure
Four shaft complexes and a surface mining operation.
Mining method(s)
Cooke 123: Conventional breast mining, scattered mining and pillar mining;
Cooke 4: Conventional breast mining, drift and benching, scattered mining and pillar mining; and
RSO: Hydraulic reclamation (water jets), gravity feed to sump pump station and pumped via pipeline to
processing plant.
Mineral processing
Three processing plants (one external):
i. Harmony Doornkop Plant – Processing Cooke 123 underground ore on a toll treatment basis for gold;
ii. Ezulwini Plant – Processing Cooke 123 No. 3 Shaft and Cooke 4 underground ore for gold and uranium; and
iii. Cooke Plant – Processing RSO tailings material for gold.

SECTION 2 THE COOKE OPERATION
Tailings disposal
One tailing storage facility (Ezulwini) with LoM deposition estimated at 7.6Mt against a capacity of 17.1Mt
(surplus of 9.5Mt).
Cooke 123 tailing via the Doornkop Plant is deposited on the Doornkop tailings facility.
Currently RSO tailings are deposited down old defunct open cast mine workings estimated to accept all planned
residue over the LoM.
Climate
No extreme climate conditions are experienced that may affect mining operations.
Environmental/Health and
Safety
Cooke systems, procedures and training are on a par with international best practice.
Life of Mine (LoM)
It is estimated that the current Mineral Reserves will sustain the operation until 2025 (based on Cooke LoM).

REVIEW
Gold Mineral Resources at Cooke decreased
by approximately 2.681Moz (-13.9%) to
16.589Moz mainly due to losses as a result
of geology models (-3,432Moz) and the pay
limit (-5,093Moz). These losses were however
largely offset by a comprehensive review of the
Mineral Resource classification and estimation
across all shafts, ensuring compliance with the
SAMREC Code in accordance with Sibanye’s
protocols and procedures (+6,789Moz) and
new areas added (+3,998Moz).
Uranium Mineral Resources at Cooke
increased by approximately 15.525Mlb
(+30.5%) to 66.385Mlb, notwithstanding
a decrease of 10.337Mlb declared for
Cooke 3 Shaft and is mainly due to the
inclusion of new ground (43.984Mlb).
white areas, the displacement of Middle
Elsburg (ME) mining areas with Upper
Elsburg (UE) areas and reduced ore reserve
development during the Section 189 at Cooke
4 (-1.794Mlb), led to an overall decrease in
Mineral Reserves.
Gold Mineral Reserves decreased by
5.5% to 1.955Moz, mainly due to depletion
(-0.226Moz). Decreasing working costs
and improvement in technical factors
led to an overall increase post depletion
(+0.112Moz). Uranium Mineral Reserves
show an overall decrease of 1.589Mlb
(29.3%) to 3.827Mlb. Despite the increase
at Cooke 3 (+0.151Mlb) due to additional
Mineral Reserve development will remain a key
performance indicator for C2015. The following
tables summarise the development advances
for Cooke 123 and Cooke 4 respectively over
the last 12 months to December 2014.

OVERVIEW
Driefontein is a large, established, shallow to ultradeep level gold mine, operating under a Mining
Right [DMR Ref. GP30/5/1/2/2(51)MR] valid from
30 January 2007 to 29 January 2037 covering a
total area of 8,561 hectares.
Geographically Driefontein is located in the West
Wits Line Goldfield of the Witwatersrand Basin,
near Carletonville, approximately 75 kilometres
west of Johannesburg in the Gauteng Province
of South Africa. Topography is characterised
by moderately undulating plains, classified as
Bankenveld consisting of grassland with livestock
farming widespread in the surrounding areas.
The current mine infrastructure consists of six
producing shaft complexes that mine open
ground and pillars (white areas), with the deepest
operating level currently some 3,420 metres
below surface (50 Level at 5 Shaft), and three
gold processing plants. The principal mining takes
place on the Carbon Leader Reef (CL), which
constitutes almost 65% of the Mineral Reserves,
the Ventersdorp Contact Reef (VCR) 31%, the
Middelvlei Reef (MR) 2% and the remaining 2%
from surface sources (SRD).

ii. Laterally continuous with relatively long-range predictability; and
iii. Clear patterns of mineralisation governed by sedimentary characteristics.
Deposit type
Shallow to ultra-deep gold mine exploiting various auriferous and uraniferous quartz pebble conglomerates
hosted by the Ventersdorp Contact Reef (VCR) and Main Conglomerate Formation [Carbon Leader Reef (CL) and
Middelvlei Reef (MR)] of the Central Rand Group.
Licence status and holdings
Driefontein has a new order mining right in terms of the Minerals and Petroleum Resources Development Act,
No 28, 2002 (MPRDA), valid from 30 January 2007 to 29 January 2037 in respect of a mining area totalling
8,561 hectares. All required operating permits have been obtained, and are in good standing.
Infrastructure
Six shaft complexes (five sub-shafts and one tertiary shaft).

Scattered stoping, mini longwall stoping with closely spaced dip pillars (140 x 40 m and 130 x 30 m regional
pillars) and surface rock dump mining.
Mineral processing
Three gold processing plants and a centralised elution and carbon treatment facility at the No 1 Plant:
i. No 1 CIP Plant – Processing underground ore and low-grade surface rock dump material;
ii. No 2 CIP Plant – Processing only low-grade surface rock dump material; and
iii. No 3 CIL Plant – Processing only low-grade surface rock dump material.
Tailings disposal
Three tailing storage facilities with LoM deposition estimated at 34.9Mt against a combined capacity of 85.2Mt
(surplus 49.7Mt).
Climate
No extreme climate conditions are experienced that may affect mining operations.
Environmental/Health
and Safety
Driefontein’s systems, procedures and training are on par with international best practice.
Life of Mine (LoM)
It is estimated that the current Mineral Reserves will sustain the operation until 2033 (for 19 years).

Competent Person(s)
The Competent Persons per mining unit (MU) designated in terms of SAMREC, that take responsibility for the
consolidation, reporting and overall compliance of Driefontein’s Mineral Resources and Mineral Reserves are the
respective Mineral Resource Managers:
MU1: 1 Shaft
Mr M Tandree [ND Mine Surveying; MSCC; GDE Mining] is a registered SAIMM member (No. 706330) and has
17 years’ experience;
MU2: 2 & 4 Shafts
Mr D Foley [GDE Mining Engineering] is a registered SAIMM member (No. 703902) and has 36 years’ experience;
MU3: 6 & 8 Shafts
Mr C Dewey [ND Mine Survey, MSCC, GDE (Mining Engineering), MSc. Eng (Mining Engineering)] is a registered
PLATO member (PMS0234) and has 40 years’ experience; and
MU4: 5 Shaft
Mr J du Plessis [MSc. (Mining Engineering), GDE Mining Engineering NHD Mine Surveying, MSCC] is a registered
PLATO member (PMS0145) and has 35 years’ experience.
Internal technical reviews have been conducted by the Competent Persons who gave their consent for the
disclosure of the C2015 Mineral Resource and Mineral Reserve Statement. All have sufficient experience relative
to the type and style of mineral deposit under consideration and are full-time employees of Sibanye.
REVIEW
The Mineral Resources at Driefontein increased
by approximately 1.627Moz (7.7%) post
production depletion to 22.880Moz, mainly as a
result of geology structure changes.
Mineral Reserves increased by 1.296Moz
(21.4%) to 7.354Moz, primarily due to the
inclusion of the 5 Shaft Drop-down Project
ounces (1.126Moz) and as a result of a detailed
investigation into the economic potential of white
areas, which were previously not considered in
the LoM plan (0.491Moz). General exclusions
amounts to 0.308Moz and are related to areas
stopped due to grade and tail managed changes
at 4, 6 and 8 Shafts.
Mineral Reserve development will remain a key
performance indicator for C2014. The following
table details the development advanced for the
last 12 months to December 2014 (C2012 and
C2013 added for comparison). A total of 17.4km
was developed in C2014 of which 3.9km was
on-reef.

OVERVIEW
Kloof is a large, established, shallow to ultra-deep
level gold mine, operating under a Mining Right
[DMR Ref. GP30/5/1/2/2(66)MR] valid from 30
January 2007 to 29 January 2027 covering a
total area of 20,087 hectares. Geographically
Kloof is located in the West Wits Line Goldfield of
the Witwatersrand Basin, near Westonaria in the
Gauteng Province of South Africa. The topography
is characterised by moderately undulating plains,
consisting mainly of grassland with livestock
farming widespread in the surrounding areas.
Kloof in its current form dates from April 2000
when the Venterspost (1939), Libanon (1945),
Kloof (1968) and Leeudoorn (1993) Mines were
amalgamated. The current mine infrastructure
consists of five producing shaft complexes that
mine open ground and pillars (white areas), with
the deepest operating level some 3,347 metres
below surface (45 Level at 4 Shaft), and two gold
processing plants. The principal mining takes
place on the Ventersdorp Contact Reef (VCR),
which constitutes almost 86% of the underground
Mineral Reserve ounces, the Middelvlei Reef
(MR) 8% and the remaining 7% comprising
mainly the Kloof Reef (KR) at 6% and the Libanon
Reef (LR) at 1%.

REVIEW
Mineral Resources at Kloof decreased by
approximately 1.049Moz (-3.5%) to 29.329Moz
post a production depletion of 0.587Moz. The
year-on-year change is mainly due to geology
structure changes (-0.899Moz) and modelling
(-0.354Moz), offset by estimation gains
(+0.787Moz).
Mineral Reserves increased by 0.877Moz
(14.6%) to 6.900Moz post a production
depletion of 0.553Moz. This increase is mainly
as a result of the 4 Shaft Drop-down Project
estimated to add an additional 0.532Moz to the
LoM. Continued investigations into the economic
potential of white areas and secondary reefs
realised an additional 0.611Moz.
Mineral Reserve development will remain a key
performance indicator for C2015. The following
table details the development advanced for the
last 12 months to December 2014 (C2012 and
C2013 numbers added for comparison). A total
of 18.7km was developed in C2014 of which
4.0km was on-reef.

KEY DEVELOPMENTS AND BROWNFIELD PROJECTS (ON-MINE)
The following projects have been included in the Kloof LoM:
• Kloof concluded a PFS on the mining of the area below 45 Level at Kloof 4 Shaft, resulting in additional Mineral Reserves of 0.532Moz
• A major exploration programme, targeted the Kloof and Middelvlei Reefs at Main and 8 Shafts, has resulted in additional Mineral Reserves
of 0.156Moz.
• The Eastern Boundary Area (EBA) Project, included in the Mineral Resources, embodies a significant high grade opportunity in the
area below 7 Shaft. Various studies conducted since the 1990s indicated that the EBA Project can be economically viable, and requires
further study.

PROJECTS OVERVIEW
Growing Sibanye’s Mineral Resources
and Mineral Reserves, ensuring a premier
All-in Cost margin, maximising earnings
and returns to shareholders requires a
fundamental understanding of the potential
of each project to extract optimal value.
Following the 2014 acquisitions, Sibanye
now has a large endowment of brownfields
projects that are at various stages of
evaluation, from early stage scoping studies
to feasibility studies that can be underpinned
by leveraging synergies off existing
infrastructure. Project evaluation criteria
have been developed to guide the Mineral
Resource and Mineral Reserve estimations.
Current delivery on major advanced and
growth projects and steps to improve the
quality of the assets, in line with Sibanye’s
strategy, includes the following:
• Project appraisal is underpinned by a
focus on value creation and dividend yield
rather than driven by growth;
• In-house project assessment capacity has
been established; and
• Each project is assessed for risk, returns
and the impact of financing on returns.

OVERVIEW
The Burnstone Project (Burnstone) is a new
gold mining operation currently under care
and maintenance, subject to the outcome of a
DFS currently in progress. The operation has
a Mining Right [DMR Ref. MP30/5/1/2/2(248)
MR] to mine and process gold, silver and
aggregate, covering a total area of 13,135
hectares, and is valid from 17 February 2009
to 16 February 2027.
Geographically Burnstone is in the South
Rand Goldfields of the Witwatersrand Basin
next to the town of Balfour, approximately
75 kilometres east of Johannesburg in the
Mpumalanga Province of South Africa.
Burnstone is accessed from the main
Johannesburg to Durban N3 highway via
the Heidelberg South R23 road at the
Balfour exit. The town of Balfour is located
Image
Exploration drilling
approximately 18 kilometres east of the N3.
The Burnstone property is accessible via a
network of unpaved roads, approximately 6.5
kilometres east of Balfour.
The Burnstone area forms part of a
physiographic region known as the South
African Highveld, lying at an altitude of
1,670 m (5,480 feet). Topographic relief
in the area is primarily a gently rolling
grassland terrain that is now intensively
farmed for maize, fodder and livestock, with
very little indigenous vegetation remaining
in the area. The climate is characterised as
mild, with warm to hot, moist summers and
cool dry winters.
Burnstone in its current form dates from
14 April 2014 when Sibanye purchased
Witwatersrand Consolidated Gold Resources
Limited and exercised the option to purchase
Southgold Exploration (Pty) Limited, the
sole owner of the Burnstone assets. The
current infrastructure consists of two shaft
complexes; a 3-leg decline and vertical shaft
(shaft bottom at 495 metres below surface),
a 125,000 tpm gold processing plant,
tailings storage facility and all the necessary
equipment and services of a producing
operation. The infrastructure for a fully
operational gold mine is largely complete.
Burnstone, under previous ownership,
produced approximately 38 koz of gold before
being put under care and maintenance in
mid-2012.
The ore body consists of the UK9 Reef of
the Kimberley Formation which constitutes
100% of the shallow underground Mineral
Resource ounces.

PROJECT FUNDAMENTALS
The Burnstone Project is situated in the South
Rand Goldfields, which is an arcuate basin
bounded by a major fault (Sugarbush Fault) to
the north, and outcropping or sub-cropping to
the south, east and west. It is separated from
the Evander Basin (which lies to the north) by
the Devon Dome. Predominantly, the major
structure is a northeast-plunging syncline, cut
by east-west striking faults. The northern limb of
this syncline is deformed by a west-northwest to
east-southeast plunging anticline, resting in the
Central Rand Group, which includes the target
Kimberley Reef (UK9). The UK9 Reef occurs at
its shallowest depth along the axis of the anticline
and consequently the Burnstone mining right is
positioned mainly along and across the anticlinal
structure where the UK9 occurs on average
between 350 and 1,300 metres below surface.
The UK9 Reef is stratigraphically split into the
UK9a and UK9b members, while the UK9a is
further laterally subdivided into either channel or
inter-channel facies. The UK9a Channel Facies
represents the primary mining horizon, while the
UK9a Inter-channel Facies and UK9b offer only
local upside potential.
Outcropping Kimberley Reef in the South Rand
Goldfields was first discovered in 1887 and
soon led to the establishment of a few small

operations that operated sporadically between
1892 and 1962 and collectively produced only
0.05Moz of gold at an average of 5.3g/t. A lack
in continuity of grade and tonnage as well as
structural complexity is commonly posed as the
reason for the demise of these operations.
In the seventies, a steep rise in the gold
price sparked renewed interest in the South
Rand Goldfields and various major mining
houses conducting fairly extensive exploration
programmes between 1974 and 1993, but
general low grades, notwithstanding at shallow
depths, resulted in a poor ranking against rival
projects elsewhere in the Wits Basin.
As a consequence, none of these projects were
advanced past the exploration phase.
Southgold Exploration (Pty) Ltd (Southgold),
incorporated in 2000, drilled an additional
18 boreholes to 2002. These were primarily
within the current Burnstone mining right area
and intermittently intersected higher grade
Kimberley Reef. In November 2002 Great Basin
Gold (GBG) acquired 100% of Southgold and
immediately embarked on an extensive surface
diamond drilling programme. Until September
2012, a further 374 boreholes were drilled,
either within, or in close proximity to the current
Burnstone mining right. Based on this drilling
programme, GBG declared a large Measured
and Indicated Gold Mineral Resource upon
which the Burnstone operation was initiated in
June 2006.

THE BURNSTONE PROJECT
CONTINUED
REVIEW
A maiden gold Mineral Resource of 54.1Mt at an
average grade of 5.1g/t for 8.890Moz has been
declared for the Burnstone Project.
KEY DEVELOPMENTS DURING 2014:
1.Initiation of an in-house pre-feasibility study
shortly after Sibanye acquired Wits Gold in
April 2014;
2.The geology models for the project have been
significantly revised after extensive re-logging
of the existing surface boreholes and detailed
underground geological mapping of accessible
development haulages and existing stopes;
3.Data gaps for meaningful Mineral Resource
evaluation and classification have been
addressed with additional infill exploration
drilling. Five surface boreholes were drilled
some distance west-northwest of the previous
mine workings;
4.The review included an updated structure model
and a detailed sedimentological study of the
UK9 Reef led to an updated facies model and
related geo-domains and trends for evaluation;
5.A thorough review and QA/QC of all the data in
line with Sibanye’s standards and procedures.
The revised model is consistent with the
characteristics of similar ore bodies in the East
Rand Basin, affording greater confidence in the
interpretation and supporting the gold Mineral
Resource estimate;
6.A maiden gold Mineral Resource estimation; and
7.DFS scheduled for completion in Q1 2015.

• Building Sibanye’s “sixth”
Operation;
• The strategic phasing of capital in
order to generate cash flow and
enhanced value;
• Considering utilisation of existing

OVERVIEW
Historically, Witwatersrand gold mine tailings
have been treated very successfully for gold
and uranium. Sibanye currently operates in a
region with a long history of gold and uranium
mining, which contains numerous old tailings
storage facilities, that contains recoverable
grades of gold and uranium.
The West Rand Tailings Retreatment Project
(WRTRP) incorporates all Sibanye’s current
and dormant tailing storage facilities (TSF)
on the West Rand, all of which form part of
new order mining rights as well as several
prospecting rights, collectively valid from
2007 to 2027 (earliest expiry date of a valid
mining right). The WRTRP assets stretch
from Randfontein to Carletonville and is

RANDFONTEIN
accessed via the local R28 highway between
Randfontein and Westonaria, or via the N12
national road between Johannesburg and
Potchefstroom.
The surface topography over the area is
characterised by moderately undulating
plains, with savannah grassland being
the natural vegetation in the area. Premining conditions were generally that of
farmlands, which is now largely built-up and
industrialised. The area is characterised
by a mild climate, with warm to hot, moist
summers and cool dry winters.
The WRTRP in its current form dates from May
2014 when Sibanye acquired the Cooke assets
from Gold One, merging the Cooke TSF assets
with that of the historic Kloof and Driefontein
WRTRP TSF assets.
PROJECT FUNDAMENTALS
The WRTRP is key to the Sibanye surface
operation’s strategy, which involves leveraging
existing surface operations and infrastructure
and developing a strong, long-life surface
business, by exploiting the low-risk and
relatively high-margin characteristics of the
surface resources located on the West Rand.
The WRTRP is well positioned to become
Sibanye’s sixth mine and also presents a
valuable environmental solution for existing
and future surface tailings, promoting socially
and environmentally responsible deposition of
tailings in a centrally managed area.
Prior to a WRTRP pre-feasibility study
a number of other studies have been
Sibanye Gold Mineral Resources and Mineral Reserves 2014

Gauss Conform Projection
Central Meridian 27°
conducted including the Gold Fields Limited
Tailings Treatment Project (DFS accuracy),
Cooke Uranium Project (DFS accuracy and
70% engineering), Gold Fields/Senet Kloof
Driefontein Complex Study (PFS accuracy)
and the West Rand Surface Optimisation
Scoping Study.
The business rationale leading to the current
Sibanye status of the WRTRP is based on the
following:
• Value accretive (NPV and IRR positive
project);
• Regional synergies add potential upside
to current value
• Remediation solution for existing and future
surface tailings;
• Extracting residual gold and uranium
unlocks value
• Leverages existing metallurgical capacity
and extends operational life
• Reduces future environmental liability
• Releases land for development
• A modular and phased design to get into
business; and
• Utilising capacity at existing
infrastructure (lower upfront capital)
• Phased and flexible capital scheduling
• Early phases partially fund later capex
• Flexibility and leverage to future
commodity prices
• Significant investment into the declining
West Rand.
• Direct and indirect job creation
SECTION 2 THE WEST RAND TAILINGS RETREATMENT PROJECT
REVIEW
The WRTRP pre-feasibility study (assessing
the potential for extraction of gold and
uranium from Sibanye’s West Wits Line and
the adjacent Cooke TSF’s), was successfully
concluded and is currently the subject of
a definitive feasibility study. The Sibanye
gold and uranium Mineral Resource and
Mineral Reserve estimate for the WRTRP are
tabulated below and are compliant in respect
of the SAMREC Code.
The gold and uranium Mineral Resources
and Mineral Reserves year-on-year remain
largely unchanged with only a small increase
in Mineral Reserves due to deposition on
active TSFs during 2014 (Gold 0.037Moz and
Uranium 1.242Mlb).
KEY DEVELOPMENTS
Studies to date confirmed the economic
viability of the WRTRP, which involves
the construction of a large-scale Central
Processing Plant for the extraction of gold and
uranium from the re-treatment of historic and
current tailings. A further objective remains
the re-deposition of the residue in accordance
with modern sustainable deposition practices,
reducing future environmental liabilities.
Sibanye’s revised strategy is to develop
the WRTRP in phases. The DSF will be
concluded during Q1 2015 and following a
successful outcome may move into a Front
End Engineering Design phase together with
the roll out of a pilot plant.

OVERVIEW
The Southern Orange Free State (SOFS)
Projects include Sibanye’s Wits Gold mining
and prospecting right holdings in the
Free State Goldfields of the Witwatersrand
Basin. The mining right consolidating
the De-Bron Merriespruit, Bloemhoek,
Hakkies and Robijn Projects into DMR
Ref. FS30/5/1/2/2(10005)MR mining right,
has been approved for a period of 23 years
and is in the process of being executed.
Geographically the mining right is situated
contiguous to the east of the Beatrix mining
right some 5km south of Virginia. The
prospecting rights are for the Beisa North
[DMR Ref. FS30/5/1/1/2(486)PR] and Beisa
South [DMR Ref. FS30/5/1/1/2(487)PR]
Projects, which are respectively contiguous to
the north and south of the Beatrix (Beisa) 4
Shaft ground. The prospecting rights
are valid until April 2016 and February
2016 respectively.
The topography of the area is relatively flat,
situated in a semi-arid region. Conditions are
generally that of farmlands, where the natural
vegetation has been removed and replaced
with cultivated crops. No extreme weather
conditions are experienced that may affect
exploration or mining operations.

The SOFS in its current form dates from
April 2014 when Sibanye acquired Wits
Gold. Sibanye is in the process of finalising a
Section 102 application seeking consent from
the Minister of Mineral Resources to amend
the Beatrix mining right by consolidating the
Beatrix mining right and the SOFS mining and
prospecting righs.
SOFS REGIONAL GEOLOGY
A three dimensional reconstruction of the
Central Rand Group stratigraphy in the
Free State Goldfield indicates a progressive
southerly thinning of the sequence, south of
the Sand River, into the SOFS mining and
prospecting right areas. This attenuation of
the Central Rand Group is related to uplift
during the latter phase of deposition in the
Basin, causing erosion by superimposed,
on-lapping unconformities. These erosional
relationships particularly affected the Basal
Reef (main economic horizon of the historic
gold mines around Welkom) that subcrops
and does not extend to the south of the Sand
River. However, four other Reefs, prospective
for gold and uranium, have been intersected
in the Central Rand Group in the area south of
the Sand River and include the Leader Reef,
the B Reef, the Aandenk/Kalkoenkrans Reef
and the Beatrix/VS5 Reef. The Beisa Reef has
also been extensively explored, as a potential
SECTION 2 THE SOUTHERN ORANGE FREE STATE PROJECTS
uranium resource, along the over-folded western
margin of the Southern Free State Goldfields.
The Beatrix/VS5 unconformity at the base of the
Eldorado Formation (Eldorado Unconformity)
is developed across the entire SOFS area and
therefore represents a reference surface for the
construction of a structural map of the area.
The resultant structure contours indicate that
the Central Rand Group is deformed in a broad
syncline, with smaller parasitic folds marking the
southern limit of the prospective Witwatersrand
Basin. This compression was responsible for
active uplift towards the southern margin of the
Free State Goldfield that resulted in a complex
interplay between a series of superimposed
unconformity surfaces. Repeated erosion of the
footwall sequences caused the incorporation and
winnowing of auriferous and uraniferous detritus
into the reefs overlying the unconformities.
The north-easterly-plunging fold has been
off-set by a series of later normal faults related
to the regional Platberg extensional event. The
normal faults generally strike north-south, the
most significant being the De-Bron Fault, which
has a relative down-throw of more than 1,000
metres towards the west. A structure of greater
magnitude, the Virginia Fault, strikes northnortheast and with a down throw to the east is
responsible for the preservation of the Central
Rand Group stratigraphy in the Robijn outlier.
The Merriespruit Thrust Fault is a southerlyverging compressional structure that has an
effective vertical displacement of 50 to 100
metre to the east of the De-Bron Fault. These
structures divide the SOFS area into four discrete
domains or project areas in which the depth of
the prospective reefs below surface will have a
profound effect on any plan to exploit
these resources.

SOFS PROJECT REVIEW
Since acquiring Wits Gold in April 2014, Sibanye has thoroughly reviewed the geological and LoM models of the De-Bron Merriespruit, Bloemhoek,
Hakkies and Robijn, and Beisa North and Beisa South Projects in the SOFS, and re-estimated the respective Mineral Resources in accordance with
the Group’s protocols and procedures and benchmark pay limits from the Beatrix Operation. Sibanye is satisfied that the potential exploitable reefs
identified and evaluated have been interpreted with a high degree of diligence with respect to their stratigraphic continuity and geology structure.
Following is a short synopsis of each project.
1. DE-BRON MERRIESPRUIT PROJECT
The De-Bron Merriespruit (DBM) Project is
located between the De-Bron Fault, which
marks the western boundary of the project,
and the Virginia Fault in the east. The
northern boundary includes the southern
extent of the old Merriespruit gold mine
obtained from Harmony, while the southern
boundary extends past the subcrop position
of the potential ore bodies (reefs). The DBM
Project is the only SOFS project that was
subjected to a feasibility study.
PROJECT FUNDAMENTALS
Four primary reef horizons containing
gold and uranium are developed on welldefined regional unconformities in the DBM
Project area. These include the Beatrix/
VS5, Aandenk, B and Leader Reefs, all of
which have been mined extensively in the
southern Free State Goldfields. The four
reefs are developed within a 20 to 40 metre
stratigraphic interval on the DBM property
and are preserved at depths of between
70
500 and 1,200 metres below surface. The,
Beatrix/VS5 and Aandenk Reefs constitute
the principal economic orebody, while the less
extensive Leader and B Reefs are regarded
as up-side potential for the Project. The reefs
are generally characterised by shallow dips of
between 10 and 25 degrees and a thickness
of 60 to 210 cm that make them suitable
for exploitation by means of typical narrow
stoping techniques similar as conducted at
the Beatrix operation.
The Leader, B and Aandenk Reefs all
subcrop against the Beatrix/VS5 unconformity
across the project area. This unconformity is
undulating to mild channel forming, causing
complex subcrop patterns.
The erosion and reworking of underlying reefs
is believed to play a strong role in controlling
the gold and uranium mineralisation in the
VS5 Reef. Consequently, gold mineralisation
increases south of the respective subcrops,
as the VS5 Reef becomes more oligomictic
Sibanye Gold Mineral Resources and Mineral Reserves 2014
due to the re-working of the underlying
material. This coincides with the development
of “Transitional Facies” of the VS5 and
eventually the Beatrix Reef facies. All four of
the above reefs contain uranium, although
the quantities are regarded as uneconomic
at current price levels and therefore has not
been included in the valuation models.
Historically a total of 72 boreholes (31
surface and 41 underground) were drilled
in the DBM Project area and immediate
surrounds. Wits Gold has drilled an additional
27 boreholes within the project area between
2006 and 2012. General consensus is that
adequate quality assurance and quality
control has been applied for the data to be
used for evaluation. Royal HaskoningDHV
subsequently completed a feasibility study
for the DBM Project in 2013, which led to a
SAMREC Code compliant Mineral Reserve
declaration by Wits Gold.

Licence status and holdings
De-Bron Merriespruit Project forms part of a mining right in terms of the Minerals and Petroleum Resources
Development Act, 2002 (Act No. 28 of 2002), in respect of an area totalling 13,135 hectares. Although the
mining right [DMR Ref. FS30/5/1/2/2(10005)MR] has been granted (25 February 2014) it still has to be
executed. The DBM portion of the mining right totals approximately 4,344 hectares.
All required permits relative to the status of the project have been obtained, and are in good standing.
Infrastructure
Exploration project of which a feasibility study has been completed in 2013. No mining activities have been
initiated yet.
Mining method
A provisional mine design caters for a standard Witwatersrand gold mine design accessing underground ore
body via a vertical and decline shaft system and utilising conventional scattered breast mining methods .
Climate
The area is characterised by a mild climate, with warm to hot, moist summers and cool dry winters. No
extreme climate conditions are experienced that may affect mining operations.
Life of Mine (LoM)
2013 feasibility study indicated an estimated LoM of 23 years (to be reviewed by Sibanye during 2015).
REVIEW
At the DBM, the application of Sibanye’s Mineral Resources estimation protocols, procedures and benchmarked pay limits, resulted in the gold
Mineral Resource declining from 10.900Moz to 4.022Moz. Subsequent updates to the economic inputs by Sibanye resulted in the uranium
Mineral Resources being omitted from the December 2014 Statement. The gold Mineral Reserves were derived from the latest revised geology and
estimation models, with the mine design and capital based on that of the original feasibility study conducted by Royal HaskoningDHV in 2013. The
gold Mineral Reserves also declined from 3.100Moz to 2.088Moz.
During 2015, Sibanye intends undertaking a full review of this feasibility study with a view to optimising any potential synergies with the Beatrix
Operation, and to optimise the mining plan in line with the restated estimation models.

SECTION 2 THE SOUTHERN ORANGE FREE STATE PROJECTS
2. BLOEMHOEK PROJECT
The Bloemhoek Project constitutes the western
extent of the SOFS mining right, covering
an area of approximately 4,060 hectares.
The southern boundary of the Bloemhoek
Project is situated a few hundred metres
north of Beatrix 3 Shaft and is enclosed to
the north by the Beatrix mining right and
bounded to the east along the De-Bron Fault.
The Bloemhoek Project was the subject of a
pre-feasibility study in 2009 conducted by
Turnberry Projects (Pty) Ltd, with subsequent
updates to the economic inputs undertaken
by Wits Gold in 2013.
in the Bloemhoek Project area, namely the
Beatrix/VS5, Aandenk, B and Leader Reefs.
Geology fundamentals described for the four
reefs at DBM are similar for the Bloemhoek
Project where the four reefs are preserved at
depths of between 1,300 metres and 2,400
metres below surface, are between 100 to
250 cm thick and generally characterised by
shallow dips of between 10 and 20 degrees.
From 1947 to 2004, a total of 28 surface
boreholes were drilled in the Bloemhoek
Project. Most of this drilling was completed by
Anglo American during the 1980s. Wits Gold
acquired the property and data in 2004 and
subsequently drilled a further four boreholes
which culminated in a pre-feasibility study,
completed in 2009 with a SAMREC Code
compliant Mineral Resource and Mineral
Reserve Statement.
PROJECT FUNDAMENTALS
Situated west of the De-Bron Fault that
separates the DBM and Bloemhoek
Projects, the same four primary reef horizons
encountered in the DBM Project are developed
REVIEW
New geological models, incorporating
borehole data from both Wits Gold and
Beatrix has resulted in a comprehensive
revision of the geology models for the
Bloemhoek Project. A combination of the
application of Sibanye’s improved Mineral
Resource estimation protocol and higher cutoff grades, has resulted in the gold Mineral
Resources decreasing from 14.000Moz
to 4.297Moz and the uranium Mineral
Resources revoked from the December
2014 declaration. The Group is reviewing
the economic viability of accessing part of
the Bloemhoek Mineral Resources from the
existing Beatrix underground infrastructure.
As a consequence, no gold Mineral Reserves
will be declared on the Bloemhoek Project
until these studies have been completed.

3. HAKKIES AND ROBIJN PROJECTS
The Hakkies Project, approximately 1,686
hectares in size, extends over an L-shaped
area due south of the Sand River, west of
the De-Bron Fault and directly north of the
Bloemhoek Project. Of all the project areas of
the SOFS mining right, the Hakkies Project,
has the most northerly location where the
thickest stratigraphic sequence, containing
the various target reefs, is preserved.
PROJECT FUNDAMENTALS
As a consequence of the Hakkies Project
location, all four of the principle reefs of the
SOFS mining right are extensively preserved
within the area. While the Beatrix/VS5 and
Aandenk Reefs are ubiquitously present,
the B and Leader Reefs subcrop against the
Eldorado Unconformity in the extreme south.
The reef facies on the Eldorado Unconformity
is dominated by the polymictic VS5 Reef,
which covers most of the Hakkies Project area.
The Robijn Project is also a subset of
the SOFS mining right with a size of
approximately 6,870 hectares and occupies
the eastern portion of the right where the
potential economic horizons are located east
of the Virginia Fault. The fault displaces the
potential economic horizons that subcrop in
the De-Bron Merriespruit Project downwards
to the east, preserving a wedge (or half
graben) of the relevant Central Rand Group
stratigraphy in the Robijn Project area.
The Eldorado Unconformity (Beatrix/VS5
basal contact) is also extensively preserved
in the Robijn Project area and is overlain by
a polymictic VS5 Reef in the north and an
oligomictic Beatrix Reef in the south of the
property. From its eastern subcrop against the
Karoo Supergroup at a depth of approximately
550 metres below surface, the Beatrix/VS5
Reef zone dips westwards to reach a depth
of 2,200 metres below surface at the Virginia
Fault. Only relatively small remnants of the
Aandenk and Leader Reefs are preserved
below the Eldorado Unconformity.
REVIEW
Sibanye has thoroughly reviewed the geology
and LoM models of the acquired Wits Gold
Hakkies & Robijn Projects and re-estimated
their gold and uranium Mineral Resources,
in accordance with the Group’s protocols and
procedures.
Subsequent updates to the economic
inputs by Sibanye resulted in the gold and
uranium Mineral Resources revoked from the
December 2014 Statement.
Sibanye intends to review the full strategic
importance of the two projects, seeking
optimisation of any potential synergies with
the Beatrix Operation, while ensuring optimal
capital employment and sustainability of the
Group’s dividend profile. No exploration is
planned for the projects in 2015.

SECTION 2 THE SOUTHERN ORANGE FREE STATE PROJECTS
4. BEISA NORTH AND BEISA SOUTH PROJECTS
The Beisa North (1,470 ha) and Beisa South
(2,580 ha) Projects are located respectively
contiguous to the north and south of the West
Section (4 Shaft) of the Beatrix Operation, some
20km west of Virginia. The economic potential
of the two prospecting rights are centred on the
uraniferous and auriferous Beisa Reef, which is
the same reef exploited by the old Beisa uranium
mine located within the Beatrix mining right.
PROJECT FUNDAMENTALS
Structurally, the Free State Goldfield lies within a
north-south trending syncline that forms an apex
in the south-western corner of the Witwatersrand
Basin. The Beisa North and South Project areas
are structurally dominated by a major overfold
structure, which is a large north trending synclinal
fold associated with the western margin of the
Witwatersrand Basin.
The plane of the Beisa Reef occurs in an inverted
sequence of overturned strata (upside down)
along the upper limits of the overfold in the target
area. The Beisa Reef dips at generally moderate
angles to the west from its eastern north south
trending subcrop against the Ventersdorp and/
or Karoo Supergroups. However, further west,
the dip of the Beisa Reef steepens to vertical in
the overfold, overturning to a normal stratigraphic
succession and dipping towards the east. The
depth below surface of the Beisa Reef is thus
structural bound and occurs from approximately
450 metres below surface, at its subcrop to
>3,000 metres below surface and the overturn.
The reef in general can be described as an
oligomictic grit to small pebble conglomerate,
5 to 50 centimetres thick consisting of well to
sub-rounded quartz pebbles set in a dark grey to
slight yellowish grey sub-siliceous quartzitic matrix
containing disseminated pyrite and carbon, with
the carbon nearly always a carbon seam (bed) of
between 1 to 15 mm thick at the base of the reef.
information on the two projects and also
concluded an initial exploration programme
comprising of three surface boreholes, drilled
between December 2009 and March 2010;
two boreholes were drilled on the Beisa North
prospecting right and one on the Beisa South
prospecting right. The exploration programme
concluded in a technical report on the Mineral
Resources of Beisa North in 2009. Sibanye has
verified the Beisa North and South Project data
and is satisfied that the data acquisition, QA/
QC and interpretation followed industry best
practices, especially the consolidation and
interpretation of historic data (surface boreholes,
company in-house technical reports, etc.).
Information pertaining to Beisa South however,
was considered inadequate for the construction
of meaningful geology models (borehole spacing
and information) and for evaluation purposes.
REVIEW
Sibanye has thoroughly reviewed the geology
and LoM models of the acquired Wits Gold Beisa
North and Beisa South Projects and re-estimated
their Mineral Resources, in accordance with the
Group’s protocols and procedures. Based on
Sibanye’s Mineral Resources estimation protocol,
under current procedures scoped in line with
the SAMREC Code, the Beisa South Project
Mineral Resources cannot be classified and was
therefore omitted from the Sibanye December
2014 Statement. The Beisa North Project gold
and uranium Mineral Resources were also
re-estimated based on the same principles
and as a result increased by approximately
5% to 1.619 Moz, while the uranium Mineral
Resources decreased by 26% to 35.373Mlb.
During 2015 Sibanye intends carrying out further
studies related to the two projects with a view
of optimising any potential synergies with the
Beatrix Operation.

Competency
The Public Report is based on work that is the responsibility of suitably qualified and experienced persons
who are subject to an enforceable Professional Code of Ethics.
Competent Person
A ‘Competent Person’ is a person who is registered with SACNASP, ECSA or PLATO, or is a Member
or Fellow of the SAIMM, the GSSA or a Recognised Overseas Professional Organisation (ROPO). The
Competent Person must comply with the provisions of the relevant promulgated Acts, have a minimum
of five years experience relevant to the style of mineralisation and type of deposit or class of deposit
under consideration and to the activity he or she is undertaking. Persons being called upon to sign as a
Competent Person must be clearly satisfied in their own minds that they are able to face their peers and
demonstrate competence in the commodity, type of deposit and the situation under consideration.
Deposit
A concentration (or occurrence) of material of possible economic interest, in or on the earth crust, that
may include mineralised material that cannot be estimated with sufficient confidence to be classified
in the Inferred category. Portions of a deposit that do not have reasonable and realistic prospects for
eventual economic extraction are not included in a Mineral Resource.
Materiality
A Public Report contains all the relevant information that investors and their professional advisors would
reasonably require, and expect to find, for the purpose of making a reasoned and balanced judgement
regarding the Exploration Results, Mineral Resources and Mineral Reserves reported on.
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, or estimated from specific geological evidence, sampling and knowledge interpreted from an
appropriately constrained and portrayed geological model. Mineral Resources are subdivided, and must
be so reported, in order of increasing confidence in respect of geoscientific evidence, into Inferred,
Indicated and Measured categories.
Measured Mineral 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
information from exploration, sampling and testing of material from locations such as outcrops, trenches,
pits, workings and drill holes. The locations are spaced closely enough to confirm geological and grade
continuity.
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 information from
exploration, sampling and testing of material gathered 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.

Inferred Mineral Resource
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 sampling and assumed but not
verified geologically or through analysis of 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.
Mineral Reserve
The economically mineable material derived from a Measured and/or Indicated Mineral Resource. It is
inclusive of diluting and contaminating materials and allows for losses that are expected to occur when
the material is mined. Appropriate assessments to a minimum of a pre-feasibility study for a project and
a LoM Plan for an operation must have been completed, including consideration of, and modification
by, realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and
governmental factors (the modifying factors). Such modifying factors must be disclosed.
Probable Mineral Reserve
Economically mineable material derived from a Measured or Indicated Mineral Resource or both. It
is estimated with a lower level of confidence than a Proved Mineral Reserve. It includes diluting and
contaminating materials and allows for losses that are expected to occur when the material is mined.
Appropriate assessments to a minimum of a pre-feasibility study for a project or a LoM Plan for an
operation must have been carried out, including consideration of, and modification by, realistic assumed
mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. Such
modifying factors must be disclosed.
Proved Mineral Reserve
Economically mineable material derived from a Measured Mineral Resource. It is estimated with a
high level of confidence. It includes diluting and contaminating materials and allows for losses that are
expected to occur when the material is mined. Appropriate assessments to a minimum of a pre-feasibility
study for a project or a LoM Plan for an operation must have been carried out, including consideration of,
and modification by, realistic assumed mining, metallurgical, economic, marketing, legal, environmental,
social and governmental factors. Such modifying factors must be disclosed.
Transparency
The reader of a Public Report must be provided with sufficient information, the presentation of which is
clear and unambiguous, to understand the report and not to be mislead.
Glossary of Terms
Term
Definition
Above Infrastructure (AI)
That part of the Mineral Resources and/or Mineral Reserves, which are above the lowest mining level and
can be accessed via the current mine infrastructure (shafts and underground haulages).
Below Infrastructure (BI)
That part of the Mineral Resources and/or Mineral Reserves which are below the lowest mining level and
that can only be accessed following approved capital expenditure.
Block Width
The average width at which it is estimated a block of ore will be mined.
Carbon-in-leach (CIL)
Gold is leached from a gold ore slurry with cyanide in agitation tanks and absorbed onto carbon granules
in the same circuit. The carbon granules are separated from the slurry and treated in an elution circuit to
extract the gold.
Carbon-in-pulp (CIP)
Gold is leached conventionally from a gold ore slurry with cyanide in agitation tanks. The leached slurry
then passes into the CIP circuit where carbon granules are mixed with the slurry and gold is absorbed
onto the carbon. The carbon granules are separated from the slurry and treated in an elution circuit to
extract the gold.
Concept Study
A study of the viability of a range of major options designed to determine the potential value of the
opportunity and confirm alignment with the business strategy. The study describes the work that needs to
be conducted to fully define the opportunity, and comprises a number of economically attractive options
that warrant further investigation.
Cut-off Grade
The lowest grade of mineralised rock, which determines as to whether or not it is economic to recover its
gold content by further concentration.
Depletion
The decrease in the quantity of ore in a deposit or property (mining right) resulting from extraction or
production.
Dilution
Waste or material below the cut-off grade that contaminates the ore during the course of mining
operations and thereby reduces the average grade mined.
Elution
Recovery of gold from the activated carbon into solution before zinc precipitation or electro-winning

Feasibility Study
A comprehensive design and costing study of the selected option for the development of a mineral
project in which appropriate assessments have been made of realistically assumed geological, mining,
metallurgical, economic, marketing, legal, environmental, social, governmental, engineering, operational
and all other modifying factors, which are considered in sufficient detail to demonstrate at the time of
reporting that extraction is reasonably justified (economically mineable) and the factors reasonably serve
as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the
development of the project. The overall confidence of the study should be stated.
Grade
The quantity of gold contained within a unit weight of gold-bearing material, generally expressed in grams
per metric ton (g/t).
Life of Mine (LoM)
Number of years that an operation is currently planning to mine and treat ore and is derived from the
current mining plan.
Mill Width
Calculated width expressing the relationship between the total reef area excavated and the total mill tons
milled from underground sources.
Mine Call Factor
The ratio expressed as a percentage which the specific product accounted for in “recovery plus residue”
bears to the corresponding product “called for” by the mine’s measuring and evaluation methods.
Pay Limit
The value at which it is estimated that ore can be mined at break-even.
Pillars
Pillars comprise of:
• Dip and strike stability pillars
• Water and ventilation pillars
• Regional stability pillars as defined by Rock Engineering
• Bracket pillars adjacent to seismically active areas or large structures
• Boundary and remnant pillars
• Abandoned pillars
Inter alia, some pillars may become available to mine once appropriate investigations and rehabilitation
have taken place.
Plant Recovery Factor
The ratio expressed as a percentage, of the mass of the specific mineral product actually recovered from
ore treated at the plant to its total specific mineral content before treatment.
Pre-feasibility Study
A comprehensive study of the viability of a range of options for a mineral project that has advanced to a
stage at which the preferred mining method in the case of underground mining or the pit configuration
in the case of an open pit has been established and an effective method of mineral processing has been
determined. It includes a financial analysis based on realistic assumptions of technical, engineering,
operating, economic factors and the evaluation of other relevant factors that are sufficient for a Competent
Person, acting reasonably, to determine if all or part of the Mineral Resource may be classified as a
Mineral Reserve. The overall confidence of the study should be stated. A pre-feasibility study is at a lower
confidence level than a feasibility study.
Reef
A gold-bearing sedimentary horizon, normally a conglomerate that may contain economic levels of gold.
SAMREC

Cecil Rhodes and
Charles Rudd, as joint
Managing Directors, are
co-founders of ‘The Gold
Fields of South Africa
Limited’ in 1887.
The Gold Fields of
South Africa Limited is
renamed Consolidated
Gold Fields of South
Africa to mine the
deep-level gold deposits
of the Witwatersrand.
Using a magnetometer,
Dr Rudolf Krahman
discovered the vast
gold deposits of the
West Wits Line near
Carletonville, including
the mines known today
as Driefontein and
Kloof.
On 12 November 1932,
West Witwatersrand
Areas Limited is formed
to take over the Gold
Fields Mineral Rights
and to continue
exploration work.
Exploration activities
between 1933 and
1939 culminate in the
registration of West
Driefontein Mining
Company on March
07, 1945. Sinking of
the No’s 1 and 2 Shafts
commences (now the
No’s 11 and 12 Shafts).
West Driefontein starts
milling in 1952.
Located on the Far West Rand, in the mining district of Oberholzer, some 70km south-west of Johannesburg in the province of
Gauteng, South Africa, Driefontein operates under new order mining rights covering a total of 8,561ha. It is an underground
mine with surface reserves represented by rock dumps and tailings storage facilities that have accumulated throughout the
operating history of the mine.

Ltd but still manages its
own lease area.
West Driefontein
succeeds Crown Mines
as the largest gold
producer ever.
East Driefontein starts
production in 1972,
with an expected life
of 52 years, and is
immediately among the
lowest cost producers in
South Africa.
Disaster strikes again in
October 1968 when a
stope in the 8 Shaft area
is flooded. It floods the
entire East Driefontein
development area and
threatens the whole of
West Driefontein. Only a
tremendous effort saves
the mines without loss
of life.
Intensive drilling carried
out between 1962
and 1963 indicates
the viability of an
area adjoining West
Driefontein mine and
the East Driefontein
Gold Mining Company
Limited is registered on
May 03, 1968.
Disaster strikes in
1962 when 29 people
tragically lose their
lives when a severe
subsidence results
in the collapse of the
entire sorting and
crushing plant on West
Driefontein.

abandoned.
Dr Krahmann used
geophysical techniques
to delineate the extent
of the reefs underlying
the dolomite.
Shaft sinking
commenced at
Venterspost using
the newly developed
cementation process.
Shaft sinking
commenced at
Libanon.
Crushing of ore began
and first gold from
