Johannesburg-based precious metals group built through a run of acquisitions after Gold Fields spun off its older South African gold mines in the early 2010s. It is one of the world's largest primary producers of platinum, palladium and rhodium and a major gold producer.

Its South African PGM mines sit on the western and eastern limbs of the Bushveld Complex, and its South African gold operations include Driefontein, Kloof and Beatrix; it also holds half of the Mimosa PGM mine in Zimbabwe. Outside Africa it runs the Stillwater and East Boulder PGM mines in Montana, the Century zinc tailings operation in Australia and the Keliber lithium project in Finland. The shares also trade in New York as SBSW.
Neal Froneman — Independent Non-executive Chair, Copper 360
Former Sibanye-Stillwater chief executive Neal Froneman became independent non-executive chair of Copper 360, replacing long-serving chair Rupert Smith, who retired from the board. The appointment of one of South Africa's best-known mining executives lifted the shares of the JSE's only pure copper play, which has been through heavy losses and repeated leadership changes.
Richard Stewart — Chief Executive Officer
Sibanye-Stillwater named long-serving executive Richard Stewart as CEO-designate from 1 March 2025, with a view to him taking over as chief executive when founding CEO Neal Froneman retired at the end of September 2025. Stewart, who had previously served as the group's chief operating officer, formally took the top job on 1 October 2025, ending Froneman's 12-year tenure at the gold, PGM and battery-metals producer.
