Sibanye-Stillwater to acquire the Santa Rita nickel mine and the Serrote copper
mine in Brazil and a withdrawal of cautionary

Johannesburg, 26 October 2021: Sibanye-Stillwater (JSE: SSW and NYSE: SBSW) is pleased to
announce that it has signed definitive purchase and sale agreements (Transaction
Agreements) with affiliates of funds advised by Appian Capital Advisory LLP (Appian) to
purchase 100% of both the Santa Rita nickel mine (Santa Rita) and the Serrote copper mine
(Serrote), located in Brazil, for a cash consideration of US$1.0 billion and a 5.0% net
smelter return (NSR) royalty over potential future underground production at Santa Rita
(the Transaction).

Commenting on the Transaction, Neal Froneman, CEO of Sibanye-Stillwater said: “The
Transaction is a significant additional step in Sibanye-Stillwater’s ongoing strategy to
position the business for continued value creation during our transition into a climate
change resilient business, and follows and complements the Keliber, Sandouville and
Rhyolite Ridge transactions announced earlier this year1. The Transaction represents a
unique opportunity for Sibanye-Stillwater to acquire significantly pre-developed and pre-
capitalised, low-cost, producing nickel and copper assets with strong ESG credentials,
which will continue to be managed by a high-quality team with a wealth of operating
experience in Brazil.”

Transaction Rationale
In line with Sibanye-Stillwater’s strategy to build an operating portfolio of green metals
and related technologies, this Transaction is a further meaningful step - adding two low-
cost, producing assets to its green metals portfolio. Both assets have been substantially
pre-capitalised and as a result the Transaction will be immediately accretive to Sibanye-
Stillwater’s cash flow and earnings.

Santa Rita is one of the largest nickel-cobalt sulphide open pit mines in the world,
located in the State of Bahia, Brazil and includes a preliminary economic assessment (PEA)-
stage underground project. The mine produces a sulphide concentrate suitable for downstream
processing to produce battery precursors and has outstanding infrastructure resulting from
significant historical investment.

Serrote is a producing open pit copper mine, currently in ramp up, located in the State
of Alagoas, Brazil and developed at a cost of US$195 million.

Santa Rita and Serrote are both low-cost and low carbon intensity operations with strong
cultural alignment with Sibanye-Stillwater’s focus on health and safety, the environment
and local communities. In addition, each asset has a well-defined pipeline of organic
growth opportunities including mine optimisation, on site resource potential and regional
exploration opportunities.

The Transaction represents an attractive opportunity to acquire two pre-developed and cash
flow generating open pit nickel and copper mines. In addition to generating a strong return
on investment based on current operations, there is substantial long-term upside from the
potential development of the underground mine at Santa Rita, with this project to be
further studied and evaluated over the next 18 months.

The Brazilian based Santa Rita and Serrote management teams are led by CEO Paulo Castellari
(previously CEO of Mubadala’s bauxite operation in Guinea and CEO of Anglo American’s
phosphates and niobium business in Brazil). The teams, which have a well-established track
record of operating in Brazil and have been responsible for successfully developing and
optimising the assets, have committed to joining Sibanye-Stillwater ensuring continuity
of expertise, knowledge, and proven mining experience. Santa Rita and Serrote, alongside
the world-class management team, represent a strong platform for Sibanye-Stillwater to
explore further growth opportunities in Brazil and throughout the Latin America region.

The Transaction
Sibanye-Stillwater has entered into two separate inter-conditional Transaction Agreements
for the acquisition of 100% of the shares in, and Appian group loans against, the 100%
owned Appian subsidiary companies which are the sole owners of Santa Rita and Serrote,
for a purchase price to be settled as follows:
•   US$1.0 billion to be settled in cash on closing (Upfront Purchase Price). The Upfront
    Purchase Price is subject to customary adjustments for net debt and working capital on
    implementation of the Transaction
•   A life of mine 5.0% NSR which will come into effect following the cumulative production
    of 252 million pounds of nickel equivalent metal, which is only expected to be payable
    once production from the underground mine commences. The 5.0% NSR is currently valued
    at US$218 million based on a preliminary economic assessment stage underground project
    which may be advanced by Sibanye-Stillwater in the future following the completion of
    further detailed studies

4The Qualified Person for the Mineral Reserve Estimate is Kenneth Kuchling, P.Eng, of P&E
Mining Consultants Inc. The estimate has an effective date of 30 April, 2021. Mineral
reserves are defined within a mine plan and incorporate mining dilution and ore losses
that result in a reduction of 1.4% of the tonnage and a 6% reduction in the Ni contained
metal with no reduction in other contained metals. Mineral Reserves are based on Measured
and Indicated Mineral Resource classifications only. Mineral Reserves are based on metal
prices of US$6.50/lb nickel, US$3.00/lb copper, US$20.00/lb cobalt, US$1,000/oz palladium,
US$800/oz platinum and US$1,250/oz gold and are constrained within an optimized pit shell
that uses 39-46°overall wall slopes, and process recoveries of 83% nickel, 70% copper and
30% cobalt with no credit for palladium, platinum or gold. An NSR cut-off value of US$8.91/t
is estimated to differentiate ore from waste. The NSR is based on cost assumptions of
US$5.17/t processing, US$1.71/t royalties, US$1.41/t site general and administrative, and
US$0.62/t corporate G&A. The estimate of Mineral Reserves may be materially affected by
metal prices, US$/BR$ exchange rate, environmental, permitting, legal, title, taxation,
soci-political, marketing, infrastructure development or other relevant issues.
