Future-Facing Metals Projects

Since 2022 the Group has continued its expansion into the future-facing metals and recycling space with a number of strategic acquisitions and

investments in the United States and Europe. The transactions completed during the last three financial years are summarised below:

*Keliber: Following on from its initial investment in the Keliber lithium project in 2021, between 2022 and 2023, Sibanye-Stillwater has

completed several transactions to augment its ownership in the project. In 2022, Sibanye-Stillwater increased its total shareholding in

Keliber to 85.9% at a total cost of EUR338 million. In 2023 the Finnish Minerals Group increased its holding in Keliber from 14% to 20% by

subscribing for EUR53.9 million of a EUR104 million rights issue. The Group's portion of the subscription (through wholly-owned subsidiary,

Keliber Lithium Proprietary Limited) amounted to EUR50.2 million. In addition to the rights issue, other minority shareholders in Keliber

(which held 0.79% of the total Keliber shareholding) for which the Group previously recognised an accelerated put option liability at 31

December 2022, received and accepted voluntary offers at the same share price (EUR157.28 per share) as the voluntary offer that

concluded in 2022. A total payment of EUR5.2 million was made by the Group to all the shareholders who accepted the voluntary

offers during June 2023. Following these transactions, the Finnish Minerals Group holds 20% in Keliber, the Group retained 79.82%, while

ix
