MARKET RELEASE

Sibanye-Stillwater progresses battery metals strategy with the exclusive put option to acquire Eramet's Sandouville nickel processing facilities

Johannesburg, 30 July 2021: Sibanye-Stillwater (Tickers JSE: SSW and NYSE: SBSW) is pleased to announce that it has entered into an exclusive put option agreement ("Put Option") with French mining group Eramet SA (Eramet) for the acquisition of 100% of the Sandouville nickel hydrometallurgical processing facility, located in Normandy, France for an effective cash cost of circa €65million*("the Transaction"). The share purchase agreement which has been agreed together with the Put Option would be entered into upon conclusion of the consultation process with the works council of Eramet Sandouville and thereafter the Transaction is expected to conclude by year end, subject to inter alia, the approval of the South African Reserve Bank and other regulatory approvals#.

The Sandouville facility is situated in the industrial heart of Europe at Le Havre, France's second largest industrial port, with strategic access to extensive logistical infrastructure including shipping, rail and key motorways, supporting any future supply into the European end user markets. The current Sandouville facilities include a hydrometallurgical nickel refinery with a production capacity of 12,000 tonnes per annum of high-purity nickel metal, 4,000 tonnes per annum of high-purity nickel salts and solutions and around 600 tonnes per annum of cobalt chloride. For more information on the transaction, please refer to https://www.sibanyestillwater.com/news-investors/news/transactions/sandouville/.

Investment rationale

The transaction is the second step in Sibanye-Stillwater's battery metals strategy, building on the investment in the Keliber lithium hydroxide project, in partnership with the State of Finland and the Finnish Minerals Group, announced in February 2021. The Sandouville site is a polyvalent facility which is already zoned for heavy industrial purposes. The site is scaleable for nickel, cobalt and lithium battery grade products, and will enable Sibanye-Stillwater to further advance its battery metals strategy and recycling activities.

Post a successful due diligence, the acquisition is seen as a low risk entry into the nickel beneficiation business and the initial focus will be on ramping up throughput as per the existing Eramet plans. As part of the due diligence Sibanye-Stillwater has completed a scoping study to in parallel with current production further upgrade the Sandouville facilities to target specific nickel battery metal products in order to unlock the full potential of these facilities and their location. A detailed investment and development plan will be provided in due course.

Neal Froneman, CEO of Sibanye-Stillwater commenting on the transaction, said: "We are delighted to progress with this second step in our battery metals strategy, which is an important step in getting further downstream exposure to the battery metals value chain. The Sandouville facility is ideally located close to the European end-user markets and well supported by significant logistical infrastructure, which will allow us to leverage our existing Platinum Group Metals relationships. We look forward to working with Eramet and the French authorities to build a leading battery metals platform in Europe."

About the Sibanye-Stillwater Group:

Sibanye-Stillwater is a leading international precious metals mining company, with a diverse portfolio of platinum group metal (PGM) operations in the United States and Southern Africa, gold operations and projects in South Africa, and copper, gold and PGM exploration properties in North and South America.

Established in 2013, the Group has grown and diversified into one of the world's largest primary producers of platinum, palladium and rhodium and is also a top tier gold producer, ranking third globally on a gold-equivalent basis. It also produces other PGMs, such as iridium and ruthenium, and chrome, copper and nickel as by- products.

Not only does the Group mine PGMs, it is also the world's leading global recycler, processor and smelter of spent PGM catalytic converter materials. In 2020, 840,000 oz of our total PGM output was recycled at our Columbus metallurgical business in Montana, in a very environmentally friendly manner.

In February 2021, Sibanye-Stillwater has advanced its global diversification strategy to encompass the battery metal space by firstly investing in a lithium hydroxide project in Finland. With the acquisition of a 30% shareholding in Keliber Oy, Sibanye-Stillwater now has a substantial interest in the Keliber lithium project currently in development phase in the Kaustinen region of Finland. The second step announced at the end of July 2021, had the Group entering into an exclusive Put option with French mining group Eramet to acquire 100% of the Sandouville nickel hydrometallurgical processing facility, located in Normandy, France.
