MARKET RELEASE
Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration as at 31 December 2020
Johannesburg, 15 February 2021: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to
report attributable Group Mineral Resources and Mineral Reserves as at 31 December 2020.
Salient features
•
A 40% increase in 4E Platinum group metals (PGM) Mineral Reserves at the SA PGM operations to
39.5M 4Eoz, primarily due to the inclusion of the Marikana K4 project (12.7 M 4Eoz) and the
Klipfontein opencast project (0.1M 4Eoz) following detailed feasibility studies.
•
A 7% (5.8Moz) increase in 2E PGM Mineral Resources, with additional Mineral Reserves of 0.8M 2E
PGM ounces defined at East Boulder Mine replacing combined depletion of 0.7M 2Eoz during 2020.
Combined stable Mineral Reserves of 26.9M 2Eoz at the US PGM operations.
•
Stable Mineral Reserves of 11.3Moz at the SA gold operations, with depletion of 1.0 Moz for 2020
off-set by
−
an 0.8Moz increase in attributable Mineral Reserves from DRDGOLD due to the increase in
Sibanye-Stillwater’s shareholding in DRDGOLD from 38.05 to 50.1%,
−
an additional 0.2Moz Mineral Reserves derived from secondary reef exploration programmes
at the Driefontein operation.
•
Mineral Resources at the SA gold operations decreased by 15.9Moz, primarily due to the exclusion
of Below Infrastructure Mineral Resources at Driefontein
The declared Mineral Resources and Mineral Reserves for our managed operations and projects are
the outcome of a detailed annual operational and life of mine (LoM) planning process and are
indicative of the considerable underlying mineral assets base which supports sustainable and robust
long-life production.
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 2021 and
will be available at www.sibanyestillwater.com/news-investors/reports/annual/.

Long term contract price
During the course of 2020, and continuing into 2021, the basket of precious metal prices has shown
strong appreciation, with the gold price driven in part by renewed sentiment for investment due to the
COVID-19 pandemic, but also due to PGM prices being supported by robust fundamentals and a
quicker than anticipated recovery in vehicle demand after the initial COVID-19 demand impact.
Spot rhodium and palladium prices have exceeded US$20,000/oz and US$2,400/oz respectively during
2021, resulting in a basket price in excess of R45,000/4Eoz at the SA PGM operations, and over
US$2,000/2Eoz at the US PGM operations. These basket prices represent margins in excess of 100% of
our assumed reserve prices.
The gold price averaged between US$1,800 and US$2,000 for the majority of 2020, which combined
with the ZAR/USD exchange rate which briefly peaked at around R19.00/US$ in early April 2020, resulted
in the rand gold price of around R1,000,000/kg for approximately seven months during mid-2020. The
current spot price of ~R900,000/kg compares favourably to the gold reserve price used of R720,000/kg,
representing a 25% margin. The table below illustrates the spot margins over the Mineral Reserve prices.

The growth in the Mineral Resource was driven by a combination of positive drilling results at East
Boulder; as well as a lowering of the cut-off grade at the East Boulder Mine, driven primarily by the
increase in the palladium Mineral Reserve price assumption.
Overall Mineral Reserves remained largely unchanged, with a slight decrease at the Stillwater mine
(Including the Blitz Project) of 0.8moz due to reduced Resource to Reserve definition drilling. This was
off-set by an increase at East Boulder, based on the positive drilling results. At the Blitz project, Mineral
Reserve definition drilling continues to underpin the project assumptions made.
A detailed reconciliation of 2019 to 2020 US PGM operations Mineral Reserves is shown in the table

2E PGM represented by Pt and Pd (Prill split Marathon: Pd (76%) Pt (24%), Denison: Pd (53%), Pt(47%))
The Altar and Rio Grande Mineral Resources remained unchanged, with no advance in earn-in by our
JV partner, Aldebaran Resources Inc.
The adjustment in attributable Mineral Resources at the Marathon Project, is due to ownership dilution
(From 80% to 20%) resulting from our JV partner, Generation Mining Limited (Gen Mining), meeting JV
milestone conditions.
The increase in attributable Mineral Resources at the Denison project is predominantly due to an
updated mineral resource estimate, incorporating additional mineralised zones.

4E PGM Mineral Reserves at the combined Marikana, Rustenburg and Kroondal operations increased
by 12.8M 4Eoz, primarily as a result of the inclusion of the Marikana K4 project (12.7M 4Eoz) and the
Klipfontein open-cast project (0.1M 4Eoz). Both the K4 project and Klipfontein open-cast project
disclosures are underpinned by feasibility studies and will be considered for development by the Board
during Q1 2021. The K4 project formed part of historic Mineral Reserve declarations by Lonmin, prior to
the acquisition by Sibanye-Stillwater, which was previously excluded from our reporting due economic
considerations. It is anticipated that, if approved, these projects will commence during 2021.
−
K4 project highlights:
·
The K4 project is a world- class brownfields project, which requires the re-start and completion
of the shaft infrastructure and is planned to extract both the Merensky and UG2 reefs over a
50 year life. Production at steady state is expected to be approximately 2,25Mtpa RoM
(~250koz 4E) per year.

6
·
Project capital requirements are estimated at R3.9 billion over eight years, with pay-back in six
years at the Mineral Reserve price assumptions.
Depletion of 2.0M 4Eoz from mining activities during 2020 was partly off-set by a 0.8Moz increase in
Mineral Reserves due to the economic parameters applied, primarily from LoM tail-end production
which had previously been excluded, now being economic at current price assumptions.

During 2020, a revised Mineral Resource Estimate for the Blue Ridge Project was completed as part of
a re-opening feasibility study, which resulted in a 0.8M 4Eoz decrease in attributable Mineral Resources
due the exclusion of an area impacted by faulting.
The Akanani, Limpopo and Blue Ridge Mineral Resource disclosures are underpinned by detailed
mining studies displaying reasonable prospect for economic extraction. The Hoedspruit area is
contiguous on strike to our Rustenburg and Marikana mining areas, and represents an attractive
near-term mining extension, underpinned by LoM scenario analysis.

50.1% Attributable, non-managed
The decrease in SA gold Mineral Resources is primarily due to the exclusion of below infrastructure
Mineral Resources at Driefontein, as this project is uneconomic at the adopted economic parameters
and assumed productivity levels.
The decrease in gold Mineral Reserves can be attributed mainly to:
−
Depletion of 1.0Moz from mining activities during 2020
−
An increase in the attributable Mineral Reserves for DRDGOLD due largely to an increase in the
shareholding percentage from 38% to 50.1%
−
Inclusion of previously excluded areas at various operations, including at Beatrix (Vlakpan and
“white areas” project), at Driefontein No. 1 and 5 Shafts (secondary reef inclusions), at Kloof Main
Shaft (Ventersdorp Contact Reef (VCR) and secondary reefs additions), at Kloof No. 4 Shaft, and
also at Driefontein No. 4 Shaft (decreases due a change in pillar design), which sum to an
additional 0.2Moz.
−
Structural geology adjustments on the VCR at the Kloof No. 4 Shaft depth extension project, which
resulted in a decrease of 0.2Moz
−
Inclusion of lower grade ore at Beatrix No. 1 Shaft, mined on an incremental, operating cost only,
basis, and the inclusion of additional payable surface sources (Surface Rock Dumps) at all
operations resulting in an increase of 0.1Moz.
−
Updates to all modifying factors (Including the Mine Call Factors) based on recent achievements
resulting in a net decrease of 0.1Moz.

The single largest impact on the Gold Projects Mineral Resources was a geological facies boundary
update at Burnstone, resulting in a decrease of 1.9 Moz.
Mineral Reserves however increased by 6% (0.2 Moz) due to a revision of the Burnstone feasibility study,
based on a revised Mineral Resource estimation model, which led to an optimisation of the Burnstone
Project mine design and schedule. A detailed reconciliation of 2019 to 2020 SA gold project’s Mineral
Reserve is shown in the table below.

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 2021 and
will be available at www.sibanyestillwater.com/news-investors/reports/annual/.
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 operations 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(SA) PGM operations statement are reported as 3E PGM + gold, which consists of
platinum, palladium, rhodium and gold. The US operations are reported as 2E PGM, which consist of
platinum and palladium.
All financial models used to determine Mineral Reserves are based on current tax regulations at
31 December 2020. Rounding of figures may result in minor computational discrepancies. Where this
happens, it is not deemed significant.
