Our PGM operations in South Africa and Zimbabwe primarily produce platinum, palladium and rhodium which, together with the gold occurring as a co-product, are referred to as 4E PGMs (by ratio approximately 58% platinum, 32% palladium, 8% rhodium and 2% gold). Significant by-products produced from these operations include chrome, copper, nickel and the secondary PGMs iridium and ruthenium.
The PGM-bearing concentrate is processed by third parties or at our precious metals refinery located in Brakpan, east of Johannesburg.
Our gold operations produce a beneficiated doré, which is then further refined at the Rand Refinery Pty. Sibanye-Stillwater has a 44% equity interest in Rand Refinery, one of the largest refiners of gold globally.
Our South African operations mine from both the UG2 and the Merensky reefs of the Bushveld complex.
Our gold operations consist of underground mining and surface treatment facilities in the Witwatersrand Basin.
