In the Americas, our two PGM operations, Stillwater and East Boulder, are located in Montana, in the United States (US). These operations extract and process PGM ore from the J-M Reef, the only known significant source of PGMs in the US and the highest grade PGM deposit in the world. They produce primarily palladium and platinum (78% Pd and 22% Pt), which are referred to as 2E PGMs. We also own and operate the Columbus Metallurgical Complex, situated in the town of Colombus, Montana, which smelts material mined to produce PGM-rich filter cake and recycles autocatalysts to recover PGMs.
Sibanye-Stillwater also has non-managed interests in a PGM exploration project – Marathon (18.19%) in Canada – and two copper-gold exploration projects in Argentina, Altar (100%) and Rio Grande (17.56%).
