Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration as at 31
December 2019

Johannesburg, 18 February 2020: Sibanye-Stillwater (Tickers JSE: SGL and NYSE:
SBGL) is pleased to report updated Group Mineral Resources and Mineral Reserves,
as at 31 December 2019.

Salient features
-   90% increase in the total Platinum Group Metals (PGM) Mineral Resources to
    389.0Moz and a 20% increase in the Group’s PGM Mineral Reserves to 55.1Moz,
    primarily due to the inclusion of the Marikana (previously Lonmin) assets,
    acquired in June 2019
-   Ongoing successful definition drilling at the Blitz project, Stillwater Mine,
    at the United States (US) PGM operations yielded 2.0Moz of additional Mineral
    Reserves
-   Gold Mineral Resources at the South African (SA) gold operations increased by
    52% primarily due to a reduction in costs associated with the Kloof integration
    project, facilitating a decrease in cut-off grades
-   Exploration projects’ advanced through the establishment of key partnerships
    including Aldebaran Resources Inc, Generation Mining Ltd and Wallbridge Ltd

The group complies with both the JSE and the US Securities and Exchange Commission
(SEC) guidelines on commodity prices used in the estimation of Mineral Reserves at
all managed operations and projects. An average exchange rate of R14.50/US$ and
the commodity prices illustrated below were used in the estimation process:

Over the past six months, PGM prices, in particular palladium and rhodium have
increased significantly. Recent spot prices of palladium have exceeded US$2,500/oz
and rhodium US$11,000/oz, resulting in increases of more than 100% and 200% over
reported Mineral Reserve prices respectively. Both the Southern Africa (SA) and US
PGM operations are exposed to these movements, with the US PGM operations
predominantly palladium rich (78% of the 2E basket), and palladium and rhodium
constituting approximately 30% and 9% of the 4E basket at the SA PGM operations.
In addition, the Rand/US$ exchange rate, is currently trading at approximately
R14.90 further enhancing the profitability of the SA operations.

  Numbers may not appear additive due to rounding

The substantial increase in the PGM Mineral Resource and Mineral Reserve base,
largely as a result of ongoing drilling at the Blitz project at the Stillwater
Mine in the US and the acquisition of Lonmin Plc, enhances the mine to market
strategy and positions the PGM operations to continue delivering value on a
sustainable basis. The inclusion of Lonmin’s projects into the portfolio has
substantially improved both the greenfields and brownfields project pipeline,
providing the Company with significant development and growth optionality under
appropriate economic circumstances.

Subsequent to the substantial but necessary restructuring that took place in 2018
and 2019 the Mineral Reserve base at our SA gold operations has remained
relatively steady during 2019,. The significant growth in Mineral Resources, which
was largely driven by a forecast reduction in costs associated with the Kloof
integration project, is pleasing, and provides for optionality under an enhanced
metal price environment

Mineral Resources remain largely unchanged with mining depletions offset by
resource growth (+2,5Moz) at the Blitz section of the Stillwater mine. The growth
in Mineral Reserves was driven by further positive drilling results at the Blitz
section of the Stillwater Mine. Ongoing external audits by independent parties
have noted that Mineral Reserve tonnages may be marginally understated and grades
marginally overstated due to the addition of unplanned mineralised dilution during
stoping.   This is not deemed to have a material impact on estimated Mineral
Reserve ounces and further definition of unplanned dilution is currently being
investigated for inclusion in future Mineral Reserve estimates, including the
implementation of scanning technology in stoping operations.

The Altar and Rio Grande Mineral Resources remained unchanged, with no advance in
earn-in by our JV partner, Aldebaran Resources Inc. During 2019, Aldebaran
Resources Inc. drilled four holes at Altar totalling 5,416 m, discovering a new
Cu-Au-Mo porphyry directly under the QDM gold resource.

During 2019, Sibanye-Stillwater concluded an agreement with Generation Mining
Limited (Gen Mining) through which Gen Mining acquired a 51% interest in the
Marathon project and formed an unincorporated joint venture with Stillwater Canada
Inc., in exchange for a cash consideration of 3.0 million Canadian dollars (CAD)
and a 12.9% equity interest in Gen Mining. Gen Mining has an option to earn up to
an 80% interest through spending of $10 million and preparing a Preliminary
Economic Assessment within four years of the property acquisition date marked as
July 11, 2019.

Gen Mining published a revised Mineral Resource estimate for the Marathon deposit
dated 9 September 2019, and has also included additional Mineral Resources at the
Geordie and Sally deposits, which forms part of the greater Marathon Property. The
total PGM Mineral Resource of the Marathon project has increased from 4Moz to
5.5Moz. Due to the transaction with Gen Mining, the attributable reported Marathon
PGM and Cu mineral resources for Sibanye-Stillwater declined by 23% and 12%
respectively.

The Mineral Resources for the Denison PGM exploration project is included for the
first time. Denison project is a PGM exploration project on the Sudbury Igneous
Complex (SIC), approximately 30km to the west southwest of the town of Sudbury.
During 2019, Sibanye-Stillwater acquired the entire shareholding in Lonmin PLC,
including the Denison project, which was 100% held by Loncan, a subsidiary of
Lonmin. During 2019, Loncan entered into a binding agreement with Wallbridge
Mining whereby Loncan has appointed Wallbridge as the operator of the Revised
Denison Property to raise the necessary funding, implement the business plan and
manage the daily operations of Loncan.    Loncan has at the end of October 2019
issued Wallbridge with 20% of Loncan (Current Loncan shareholding is currently 80%
Lonmin and 20% Wallbridge).

The large increase in 4E PGM Mineral Resources was primarily due to the inclusion
of the Marikana assets (124.3Moz), which were acquired through the Lonmin
acquisition. 4E PGM Mineral Reserves at the Rustenburg, Kroondal and Mimosa
operations decreased by 1.4Moz, primarily as a result of depletion of 1.6Moz from
mining activities during 2019, partly off-set by 0.2Moz increase due to the latest
life of mine scheduling.

A thorough review of the historic (Sept 2018) 4E PGM Mineral Reserves at the
Marikana Operations, post the takeover of these assets by Sibanye-Stillwater in
June 2019, resulted in a decrease of 22.1Moz primarily due to:
   - Depletion of 1.2Moz from mining activities during 2019 (15 months Oct 2018 to
     Dec 2019)
   - Reduction of 1.1Moz due to an updated geological interpretation influencing
     design and scheduling.
   - Reduction of 1.5Moz due to the application of the economic evaluation
     process.
   - Removal of Mineral Reserves of 11.7Moz from operations on Care and
     Maintenance without the requisite feasibility studies in line with Sibanye-
     Stillwater’s policy.
   - Removal of Mineral Reserves of 11.8Moz from projects below infrastructure
     which are not included in the life of mine.
   - Feasibility studies are currently being conducted on selected projects to
     confirm economic viability at current economic parameters which may
     positively impact future mineral reserve estimations.

-   The decrease was partially offset by:

    -   An addition of 0.3Moz included under the Marikana Mineral Reserves identified
        as a synergistic benefit.
    -   Sibanye-Stillwater has reported reserves on an attributable basis of 95.25%,
        increasing the total reported Mineral attributable Reserves by 4.9Moz in line
        with Group policy.

The inclusion of Akanani and the larger Limpopo project have dramatically enhanced
the Group’s project pipeline. These projects provide the company with significant
short-term and longer-term growth options, with Akanani being a high-quality
resource on the Plat Reef, amenable to bulk mining methods, and Limpopo being a
well maintained operation under care and maintenance.

The increase in SA Gold Mineral Resources is primarily due to the use of lower
cut-off grades at the Kloof operation. The planned pay-limits at this operation
reduced due to cost savings realised from the Kloof integration project.    This
project is designed to close the unprofitable Kloof 3 and Kloof 7 shafts, and to
increase production at Kloof 8 and Kloof Main Shafts, which will result in
increased volumes and lower fixed costs.

The decrease in Gold Mineral Reserves can largely be attributed to:
   - Depletion of 0.8Moz from mining activities during 2019
   - Changes in the Mineral Resource model for the Ventersdorp Contact Reef (VCR)
     at Kloof 4 Shaft, which contributed to an overall decrease for Kloof of
     0.3Moz
   - Structural geology adjustments on the Carbon Leader Reef (CLR) at Driefontein
     5 Shaft, which resulted in geotechnical pillar adjustments and which
     contributed to an overall decrease at Driefontein of 0.5Moz
   - These decreases were offset by an extension of the Beatrix 4 Shaft Life of
     Mine (0.5Moz), where the operation has shown continued profitability
     following rationalisation in 2018.

The single largest impact on the Gold Projects Mineral Resources was the exclusion
of the attributable portion of the DRDGOLD underground resource at ERPM, following
the flooding of the underground workings, resulting in a decrease of 14.8Moz. In
January 2020, Sibanye-Stillwater exercised its option to increase its shareholding
in DRDGold to 50.1%.    This increase in shareholding will positively impact the
Company’s attributable Gold Mineral Resources and Mineral Reserves in future
reporting periods. The other material impact was at the Kloof Below Infrastructure
(BI) Mineral Resources, which decreased by 4Moz due to an update in the estimation
model.   The estimation domains were adjusted in line with changes in the facies
for the EBA area, as well as constraining the estimate in the areas with a lack of
borehole information by using the Global Mean for simple kriging.

Mineral Reserves remained unchanged.

-   Corporate Governance

Sibanye-Stillwater reports its Mineral Resources and Mineral Reserves in
accordance with the SAMREC Code, the updated Section 12 of the JSE Listings
Requirements; and in consideration of the SEC Industry Guide 7, which is aligned
with the guiding principles of SOX. Recent amendments adopted by the SEC to
modernise the property disclosure requirements for mining registrations, which has
not come into effect fully yet, aligns closely with the requirements under the JSE
and SAMREC, and any non-compliance to SEC Industry Guide 7 is therefore considered
immaterial. The Altar, Marathon and Rio Grande Mineral Resources were originally
compiled under NI 43-101 guidelines but are deemed to be SAMREC compliant.

This Mineral Reserve and Mineral              Resource declaration represents a condensed and
consolidated summary of the full              Sibanye-Stillwater Mineral Resource and Mineral
Reserve declaration available in              the Group Mineral Resource and Mineral Reserve
Report, which will be published                on 22 April    2020 and will be available at
www.sibanyestillwater.com


Guided by a commitment to best practice corporate governance, the statement has
been reviewed and confirmed by each segment’s Technical Services.

The Mineral Resources and Mineral Reserves are estimates at a particular date, and
are affected by fluctuations in mineral prices, the ZAR/US$ exchange rate,
operating costs, mining permits, changes in legislation and operating factors.
Although all permits may not be finalised and in place at the time of reporting,
there is no reason to expect that these will not be granted.

All statement figures are managed by Sibanye-Stillwater with the exception of
those for Mimosa, the attributable portion for DRDGOLD and the US Projects.
Mineral Resources are reported inclusive of Mineral Reserves, and production
volumes are reported in metric tonnes (t).

Gold and Uranium estimates are reported separately from each other; therefore, no
Gold equivalents are stated to avoid potential anomalies as a result of year-on-
year metal price differentials.

The Southern African PGM Operations statement are reported as 3E PGM + Au, which
consists of platinum, palladium, rhodium and gold. The US operations are reported
as 2E PGM, which consist of platinum and palladium.

The individual proportions of the reported PGM’s are provided in the tables below.

FORWARD LOOKING STATEMENTS

The information in this announcement may contain forward-looking statements within the meaning of the “safe

All statements other than statements of historical facts included in this announcement may be forward-looking
statements. Forward-looking statements also often use words such as “will”, “forecast”, “potential”, “estimate”,
“expect” and words of similar meaning. By their nature, forward-looking statements involve risk and uncertainty

factors, including those set forth in this disclaimer and in the Group’s Annual Integrated Report and Annual
Financial Report, published on 29 March 2019, and the Group’s Annual Report on Form 20-F filed by Sibanye-
Stillwater with the Securities and Exchange Commission on 5 April 2019 (SEC File no. 001-35785), and the Form F-4

The important factors that could cause Sibanye-Stillwater’s actual results, performance or achievements to differ
materially from those in the forward-looking statements include, among others, our future business prospects;
financial positions; debt position and our ability to reduce debt leverage; business, political and social
conditions in the United States, United Kingdom, South Africa, Zimbabwe and elsewhere; plans and objectives of
management for future operations; our ability to obtain the benefits of any streaming arrangements or pipeline
financing; our ability to service our bond Instruments (High Yield Bonds and Convertible Bonds); changes in
assumptions underlying Sibanye-Stillwater’s estimation of their current mineral reserves and resources; the
ability to achieve anticipated efficiencies and other cost savings in connection with past, ongoing and future

ability of Sibanye-Stillwater to comply with requirements that they operate in a sustainable manner; changes in
the market price of gold, PGMs and/or uranium; the occurrence of hazards associated with underground and surface
gold, PGMs and uranium mining; the occurrence of labour disruptions and industrial action; the availability,
terms and deployment of capital or credit; changes in relevant government regulations, particularly
environmental, tax, health and safety regulations and new legislation affecting water, mining, mineral rights and
business ownership, including any interpretations thereof which may be subject to dispute; the outcome and
consequence of any potential or pending litigation or regulatory proceedings or other environmental, health and
safety issues; power disruptions, constraints and cost increases; supply chain shortages and increases in the
price of production inputs; fluctuations in exchange rates, currency devaluations, inflation and other macro-
economic monetary policies; the occurrence of temporary stoppages of mines for safety incidents and unplanned
maintenance; the ability to hire and retain senior management or sufficient technically skilled employees, as
well as their ability to achieve sufficient representation of historically disadvantaged South Africans’ in
management positions; failure of information technology and communications systems; the adequacy of insurance
coverage; any social unrest, sickness or natural or man-made disaster at informal settlements in the vicinity of
some of Sibanye-Stillwater’s operations; and the impact of HIV, tuberculosis and other contagious diseases. These
