In the Americas, our operations consist of the Stillwater and East Boulder mines in Montana, where we extract ores from the J-M Reef. The J-M Reef is a geological formation which is the only known significant source of PGMs in the US and the highest grade PGM deposit known in the world. We also own and operate smelting and refining facilities in Columbus, Montana.

In addition, we own the PGM-copper exploration Marathon project near the town of Marathon, Ontario, and maintain an interest in the Altar and Rio Grande copper/gold projects in San Juan Province in northwest Argentina.

Our US PGM operations primarily produce palladium and platinum (78% Pd and 22% Pt), which are referred to as 2E PGMs. The mined PGM-bearing ore is processed, smelted and refined to produce a PGM-rich filter cake; a third party further refines the filter cake to produce refined PGM metals.
