"Juicy" mine ripe for expansion, says Sibanye

Sibanye-Stillwater CEO Richard Stewart called the Mt Lyell copper project in Australia 'juicy' with expansion potential. The R5.5bn project, approved for 2026, aims to produce 26,000 tons of copper annually by 2029, along with gold and silver by-products. The company plans to spend R3.5bn on the Burnstone gold mine in South Africa. Copper prices have risen 73% since 2023, influencing the decision. Stillwater's US operations face cost-cutting challenges.
