Sibanye’s diversification into platinum-group metals — from its original dependence on aging South African gold mines — yielded bumper profits in the early years of this decade. Now slumping prices are forcing the company to slash costs and reduce its workforce both at home and in the US.

Sibanye rose as much as 9.2% in Johannesburg trading.

The restructuring is likely to result in platinum and palladium production from the Stillwater assets being reduced by approximately 200 000 ounces in 2025. Sibanye is forecasting output of 440 000-460 000 ounces this year.

The Johannesburg-listed company posted a first-half loss of R7.1 billion ($396 million).
