Stillwater Mining Company is engaged in the development, extraction, processing, smelting, refining and marketing of palladium, platinum and associated metals from a geological formation in southern Montana known as the J-M Reef. This is the only known significant source of platinum group metals (PGMs) in the United States and one of the significant resources outside of the Russian Federation and South Africa. Platinum group metals are rare precious metals used in diverse applications for auto catalysts, fuel cells, hydrogen purification, electronics, jewelry, dentistry, medicine, coinage and other uses.
The Company owns the Marathon PGM-copper deposit in Ontario, Canada. This project is presently in the permitting stage. In addition, the Company owns the Altar porphyry copper-gold deposit located in the San Juan province of Argentina. The Company is currently advancing the delineation of this resource.
The Company conducts mining operations at its Stillwater and East Boulder mines in south-central Montana. The primary product produced at the Company’s mines is palladium. Concentrating plants are located at both mines to upgrade ore to a concentrate. The Company operates a smelter, refinery and laboratory at Columbus, Montana to further upgrade the concentrate to a PGM-rich filter cake. The Company also processes spent catalyst material through its recycling facility to recover PGMs.
Stillwater Mining Company’s corporate office is located in Billings, Montana.
