MARKET RELEASE

**Sibanye-Stillwater Mineral Resources and Mineral Reserves declaration as at 31 December 2025**

**Johannesburg, 17 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 2025.

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. In addition,

attributable Mineral Resources and Mineral Reserves are also declared based on our legal interest in non-

managed mineral properties.

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 24 April 2026 at

www.sibanyestillwater.com/news-investors/reports/annual/.

**1. Salient features**

• 4E PGM Mineral Resources of 138.2Moz (-4.5%) and Mineral Reserves of 29.4Moz (+4.7%) at our SA PGM

operations

–The inclusion of the Marikana E4 mechanised UG2 project Mineral Reserves added +2.9Moz to Mineral

Reserves following the completion of a feasibility study

• 2E PGM Mineral Resources of 57.5Moz (+2.8%) and Mineral Reserves of 19.4Moz (+2.1%) at our US PGM

operations

• Gold Mineral Resources of 25.2Moz (-31.7%) and Mineral Reserves of 9.4Moz (-6.3%) at our SA gold

operations (including DRDGOLD) and development projects (including Burnstone)

–At the Kloof operation, production constraints, including geotechnical considerations which led to the

removal of isolated blocks of ground, have impacted the economic viability of the operation, leading

to a writedown of the majority of the Mineral Reserves (-1.4Moz)

• Uranium Oxide (U3O8) Mineral Resources of 33.1Mlb (-44.1%) and Mineral Reserves of 25.2Mlb at our SA gold

operations

–The maiden uranium Mineral Reserve is based on the completion of the Cooke TSF feasibility study

–The reduction in Mineral Resources is informed by the conversion to Mineral Reserves

• Lithium Mineral Resources of 263kt lithium carbonate equivalent (LCE) (-38.0%) and Mineral Reserves of

248kt (unchanged)

–The change in Mineral Resource is informed by the disposal of our interest in Ioneer Ltd (-201kt) and an

updated Mineral Resource estimate at the Keliber lithium project (+40kt) in Finland following successful

exploration

• Zinc Mineral Resources of 568kt (unchanged year-on-year) and Mineral Reserves of 308kt (-44.2%)

–Informed by the ongoing depletion of the tailings Mineral Reserve at the Century operation, which now

has ~18 months of reserve life left

• Copper Mineral Resources of 5,006kt (-37.3%) and Mineral Reserves of 478kt

–At the Mt Lyell copper project in Tasmania, Australia, the completion of the feasibility study has resulted

in a maiden Mineral Reserve under Sibanye-Stillwater. This also informed a reduction in Mineral

Resources at Mt Lyell

–At the Altar project in Argentina, a reduction in project ownership (40% to 20%) following a further earn-

in by Aldebaran Resources, has resulted in an attributable Mineral Resource reduction (-2,478kt)

The Mineral Resources were largely stable, only

impacted by mining depletion and conversion to

Mineral Reserves at KTD1 TSF and the Marikana E4

project. Noteworthy is that the Kroondal and SRPM

Mineral Resources and Mineral Reserves have been

consolidated under SRPM due to the

amalgamation of the operations.

A detailed reconciliation of the 2024 to 2025 SA

PGM operations Mineral Reserves is shown in the

table below.

For the Mineral Reserves, apart from depletion

(-1.8Moz), the following aspects informed the

changes:

• Marikana operation, where the E4 Mechanised

UG2 project, for which a feasibility study has

been completed, has been included in the

Mineral Reserves for the first time (+2.9Moz). This

project is a capital efficient, high margin,

shallow, mechanised room and pillar,

brownfields opportunity

• The inclusion of the Marikana KTD1 TSF (+0.6Moz)

• Minor adjustments due to geological

interpretation, estimation methodology,

economic valuation and a change in modifying

The change in the Mineral Resources, apart from

mining depletion, were principally driven by:

• Kloof operation, due to the exclusion of Mineral

Resources below 35 level (due to 7 shaft closure)

and the exclusion of the majority of high-grade

VCR Resources due to rock engineering

constraints

• Driefontein operation, due to the exclusion of

inaccessible areas relating to infrastructure

constraints at 8 shaft

• DRDGOLD, with the removal of the

Daggafontein TSF due to being reclassified as a

depositional site; and the Grootvlei TSF due to

regulatory and legal considerations

A detailed reconciliation of the 2024 to 2025 SA

Gold operations Mineral Reserves is shown in the

below table.

For the Mineral Reserves, apart from depletion

(-0.6Moz), the following aspects informed the

changes:

• Kloof operation, where production constraints,

including geotechnical considerations which led

to the removal of isolated blocks of ground,

have impacted the economic viability of the

operation, leading to a writedown of the

majority of the Mineral Reserves (1.4Moz)

• Driefontein operation, where the depletion

(0.2Moz) was offset by one year life extensions at

4 shaft and 5 shaft (0.3Moz)

• Beatrix operation, where the LoM was extended

by three years through the inclusion of below

infrastructure mining, an extension into the

Vlakpan area and a reduced production rate

• Cooke operation, where the gold content from

the Cooke TSF uranium project is included for

the first time following the successful feasibility

study

• DRDGOLD, where the Daggafontein TSF

(0.7Moz) was excluded, and the Crown

Complex (1.1Moz) was added

**4.1.2.2. SA gold - Burnstone development project**

• Total gold Mineral Resources of 5.5Moz, a year-on-year decrease of -0.3%

• Total gold Mineral Reserves of 2.7Moz, a year-on-year increase of +7.2%

A feasibility study into the re-commencement of

construction at the Burnstone project is ongoing,

with a decision expected during 2026. As part of

this work, the Mineral Resource and Mineral Reserve

estimates were revisited, leading to minor

adjustments, largely relating to a change in

geological domaining and mine design and

scheduling.

The feasibility study into the exploitation of the Cooke TSF (gold and uranium) was completed, leading to a

maiden uranium Mineral Reserve. This informed the decrease in Mineral Resources. The gold Mineral Resources

and Mineral Reserves within the TSF is reported within the SA gold tables.

The Beisa Mineral Resource, previously reported as subject to a pending transaction with Neo Energy Metals,

expected to close in 2026, is still included.

*2E PGM = Pt (22%) + Pd (78%)*

The year-on-year change in Mineral Resources,

apart from mining depletion and conversion to

Mineral Reserves, were primarily driven by an

adjustment in estimation methodology and an

update to the geological loss calculation.

A detailed reconciliation of the 2024 to 2025 US

PGM operations Mineral Reserves is shown in the

below table.

Aldebaran Resources Ltd (Aldebaran), the operator of the project, has acquired an additional 20% interest in

the Altar project, after satisfying the requisite earn-in expenditure threshold, bringing its total interest to 80% (up

from 60% as at 31 December 2024). Following this, the Group's combined attributable interest of 31.47% (48.61%

in 2024) derives from a 14.34% equity interest in Aldebaran and a direct 20% (40% in 2024) project level interest.

This has led to a reduction in attributable Group Mineral Resources.

Noteworthy is that Aldebaran has completed a Preliminary Economic Assessment (PEA) during the year for an

open pit mining operation of what is one of the largest undeveloped copper Mineral Resources worldwide.

The increase in Mineral Resource is due to ongoing,

successful exploration activities which led to the

identification of further mineralisation at the

Leviäkangas and Tuoreetsaaret deposits. This

prompted a Mineral Resource estimate update

(+40kt). In parallel, adjustments have also been

made to our Mineral Resource cut-off grade

(reduced to 0.18% Li2O), to bring it in line with the

latest estimated mining cut-off grades.

The Mineral Reserves at the Syväjärvi and Rapasaari

open pit mines for the first 18 years of the

production are unchanged.

The year-on-year change in Mineral Reserves were driven solely by mining depletion of the finite TSF Mineral

Reserves. The TSF will be depleted by mid-2027, and the Group is studying commercial options (regional

phosphate mining partnerships) to extend the life of the significant fixed infrastructure which includes a

processing plant, pipeline, port facility and maritime shipping vessel.

The Class 2 feasibility study into the reopening of the historic Mt Lyell mine in Tasmania has been concluded,

leading to a maiden copper-gold Mineral Reserve. The project envisages a 3Mtpa operation, with an initial 23

year LoM, producing approximately 26ktpa of copper and 16kozpa of gold in concentrate. This also informed

the reduction of the Mineral Resources.

**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 24 April 2026 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 2025. 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 14 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, full-time employee of Sibanye-Stillwater 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).
