MARKET RELEASE
Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration as at 31 December 2024
Johannesburg, 19 February 2025: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to report
attributable Group Mineral Resources and Mineral Reserves as at 31 December 2024.
The declared Mineral Resources and Mineral Reserves for the Group's 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, long-life production.
CEO, Neal Froneman commented: "We continue to grow and diversify our mineral asset portfolio in our
preferred commodities. Our diversified portfolio, with its gold underpin, has demonstrated its value during these
times of lower PGM prices. This also supports the Group while we build on the company's strategy of producing
green metals that will play a critical role in future energy solutions. In this regard, the 36.6% increase in
attributable lithium Mineral Reserves at the Keliber lithium project, and the 20.8% copper Mineral Resource
growth at the Mt Lyell copper project, are particularly pleasing."
This Mineral Resources and Mineral Reserves declaration represents a condensed and consolidated summary
of the full Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration, which will be available in the
Group Mineral Resources and Mineral Reserves Report. The report will be published on 25 April 2025 at
www.sibanyestillwater.com/news-investors/reports/annual/.
1. Salient features
- Stable 4E PGM Mineral Resources of 180.8Moz (-1.1%) and Mineral Reserves of 28.1Moz (-0.2%) at our SA
PGM operations, which are positioned for profitability at current spot 4E PGM basket prices
- A highlight is the inclusion of the Siphumelele mechanised UG2 project Mineral Reserves (0.8Moz),
demonstrating the value being unlocked through the acquisition of the remaining 50% interest in the
Kroondal operations
- 2E PGM Mineral Resources of 79.1Moz (-9.9%) and Mineral Reserves of 19.0Moz (-27.8%) at our US PGM
operations
- Sustained low 2E PGM spot prices during the year has necessitated an operational restructuring as well
as a strategic shift in extraction strategy at the US PGM operations. In combination with a lower 2E LoM
basket price assumption, this has impacted the operation's Mineral Resources and Reserves
- Gold Mineral Resources of 48.8Moz (-2.2%) and Mineral Reserves of 10.0Moz (-8.0%) at our SA gold
operations and projects (including DRDGOLD)
- The reduction in Reserves is largely driven by depletion and geological changes at Driefontein
- A 36.6% increase in attributable lithium Mineral Reserves to 248kt of lithium carbonate equivalent (LCE)
- Informed by an updated Mineral Reserve estimate at the Keliber lithium project in Finland
- The new open pit LoM is now 18 years, with first lithium hydroxide production due in early 2026
- Zinc Mineral Resources of 2,570Mlb (-14.4%) and Mineral Reserves of 1,218Mlb (-29.4%)
- Informed by the depletion of the tailings Mineral Reserve at the Century operation
- Copper Mineral Resources of 17,604Mlb (+116%)
- At the Mt Lyell copper project in Tasmania, Australia, an update to the Mineral Resource estimate has
added 335Mlb of contained copper
- At the Altar project in Argentina, an update to the Mineral Resource estimate added 9,106Mlb of
attributable copper Mineral Resources
- Uranium (U3O8) Mineral Resources of 59Mlb, unchanged year-on-year
- This excludes the pending completion of the Beisa (27Mlb) sales transaction with Neo Energy Metals Ltd
(Neo), expected to close in early 2026, in exchange for R250m in cash and R250m in shares (40%) in Neo

3. About our disclosure and related assumptions
The Group reports in accordance with both the JSE and the US Securities and Exchange Commission (SEC) rules
and guidelines for the estimation of Mineral Resources and Mineral Reserves at all managed operations,
development, and exploration properties. This specific disclosure is in compliance with the JSE rules, while the
SEC compliant version can be located at https://www.sibanyestillwater.com/download/reserves-resources-
dec2024-nyse.
Forward looking prices, based on extensive market research, are used in the Mineral Resources and Mineral
Reserves estimations. Price assumptions for Mineral Resources focus on longer timeframes and are based on
moderately higher prices than for Mineral Reserves, demonstrating their reasonable prospects for economic
extraction and ore-body flexibility. The commodity prices used in the estimation of Mineral Resources and
Mineral Reserves at non-managed entities, over which we don't have control, are provided in the notes to the
relevant tables.
Given the decline in the PGM markets, we have adjusted our palladium and rhodium price outlook
downwards. We now forecast palladium at US$1,150/oz (2023: US$1,250) and rhodium at US$4,500/oz (2023:
US$6,000). The long-term outlook of US$1,250/oz for platinum is maintained based on expected mine depletion,
which will lower supply, and the expected realisation of hydrogen demand.
The ongoing global polarisation and the increased associated risk, as evidenced by the wars in Ukraine and
the Middle East, has continued to drive gold prices higher. Combined with lingering above-average inflation
levels, we have seen a new structural floor develop for gold. At our leveraged South African gold operations,
we have considered the most recent bank consensus forward-looking prices (Years 2025-2028) for Mineral
Reserves estimation before reverting to a higher but still conservative long-term outlook of US$1,750/oz (2023:
US$1,650).
Regarding base metals, we have revised our longer-term price outlooks for chrome ore and uranium. Over the
past year we have seen sustained +40% chromium oxide (Cr2O3) UG2 concentrate prices well above US$200/t
and, in line with bank consensus, we have adjusted our long-term price to US$230/tonne. The structural support
for a sustained uranium market rally continues to grow, underpinned by the growing recognition of uranium as
a source of green energy and as a crucial contributor to the global decarbonisation requirements in future. As
a result, we have adjusted our view of the long-term contract price to US$63/lb. This bodes well for the future of
the Cooke tailings storage facility (TSF) uranium project, which is undergoing a feasibility study (FS).
For the Keliber lithium project, where we have comprehensively updated the Mineral Reserve estimate via
detailed new pit designs, we have taken cognizance of the weaker current, short term outlook and have
considered a Li price of ~US$20,000/t lithium hydroxide monohydrate (LiOH.H2O).
The exchange rates applied for the South African Mineral Resources and Mineral Reserves calculations as at 31
December 2024 is ZAR18.24:US$ (up from ZAR17.00:US$ at end 2023), reflecting the continuing deteriorating
long-term ZAR:US$ outlook. Other rates applied are US$1.12:EUR, ZAR19.80:EUR and US$0.71:AUD.

The Group has an agreement with Ioneer Limited to establish a 50:50 JV with respect to the Rhyolite Ridge
project in Nevada, subject to the satisfaction of all conditions precedent. On 25 October 2024, a positive
Record of Decision (ROD) was issued by the US Bureau of Land Management, completing a major US Federal
permitting step and advancing the project toward a construction decision. The Group is currently reviewing
Ioneer's updated studies, one of several outstanding conditions precedent, in order to inform a final investment
decision.
During April 2024, Ioneer announced an updated Mineral Resource estimate for the South Basin at the project,
showing a slight reduction in total content, but a significant improvement in the proportion of Measured and
Indicated Resources. Accordingly, the Group's attributable Mineral Resources have been adjusted based on its
6.19% listed-level investment in Ioneer.

After successful exploration drilling, Aldebaran Resources, the project manager, published an updated Mineral
Resource estimate on 25 November 2024. The new estimate totals Measured & Indicated Mineral Resources of
2.40 billion tonnes, with grades of 0.42% copper, 0.07 g/t gold, 1.22 g/t silver, and 42 g/t molybdenum.
As at 31 December 2024, Aldebaran has given notice that they have crossed the threshold to acquire an 80%
interest in the Altar project from Sibanye-Stillwater (up from 60% as at 31 December 2023), pending final
audited financials. This is expected to become official during early 2025, and until such time the attributable
reporting remains based on a 40% project level interest and a 14.34% direct corporate level interest for a
combined 48.61% attributable interest.

5. Corporate governance
This Mineral Reserves and Mineral Resources declaration represents a condensed and consolidated summary
of the full Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration, available in the Group
Mineral Resources and Mineral Reserves Report. The report will be published on 25 April 2025 and will be
available at www.sibanyestillwater.com/news-investors/reports/annual/.
The Mineral Resources and Mineral Reserves are estimates at a particular date, and are affected by
fluctuations in mineral prices, exchange rates, operating costs, mining permits, changes in legislation and
operating factors.
Sibanye-Stillwater prepares and reports its Mineral Resources and Mineral Reserves in accordance with the
SAMREC Code, the updated Section 12 of the JSE Listings Requirements, and the SEC regulation S-K Sub-part
1300. For non-managed mineral properties, Mineral Resources and Mineral Reserves are in certain cases
prepared under different codes, such as JORC and NI-43-101. These codes are closely aligned with SAMREC,
and form part of CRIRSCO (Committee for Mineral Reserves International Reporting Standards). Therefore, the
estimates are deemed to be consistent with SAMREC and S-K1300.
Production volumes are reported in metric tonnes (t). By-product metals that do not constitute material
contribution to potential revenue flows are typically excluded from the estimates, but are included in the
economic assessments.
All financial models used to determine the managed Mineral Reserves are based on current tax regulations as
at 31 December 2024. Rounding of figures may result in minor computational discrepancies. Where this
happens, it is not deemed significant.
There are Competent Persons (CPs), designated in terms of the respective national reporting codes, who take
responsibility for the reporting of Mineral Resources and Mineral Reserves at the respective operations and
projects. Corporate governance on the overall compliance of the Group's figures and responsibility for the
generation of a Group consolidated statement has been overseen by the Group's lead CP, included below.
The Group has the written confirmation of the lead CP that the information, as disclosed in this report, is
compliant with the relevant security exchanges' listing requirements (Section 12 of the JSE listing requirements,
SAMREC Table 1 and the US SEC SK1300), and that it may be published in the form and context in which it was
intended.
For the managed operations, Stephan Stander is the Group Lead CP for Mineral Resources and Mineral
Reserves. Stephan is a registered member of the South African Council for Natural Scientific Professions
(SACNASP 400089/96).
