Stillwater Mining Company is the only U.S. miner of platinum group metals (PGMs) and the largest primary producer of PGMs outside of South Africa and the Russian Federation. PGMs are rare precious metals used in a wide variety of applications, including automobile catalysts, fuel cells, hydrogen purification, electronics, jewelry, dentistry, medicine and coinage. The Company is engaged in the development, extraction and processing of PGMs from a geological formation in south-central Montana recognized as the J-M Reef. The Company also recycles PGMs from spent catalytic converters and other industrial sources. The J-M Reef is the only known significant source of PGMs in the United States and the highest-grade PGM deposit known in the world.
The Company conducts mining operations at its Stillwater and East Boulder mines. Concentrating plants located at both mines upgrade extracted ore to concentrate. The Company operates a smelter, refinery and laboratory at its metallurgical complex in Columbus, Montana, to further upgrade the concentrate to a PGM-rich filter cake. Another key segment of the Company’s operations conducted at the complex is recycling of spent catalyst material to recover PGMs
