| Stillwater Mining Company is engaged in the development, extraction, processing, refining and marketing of palladium, platinum and associated metals (platinum group metals or PGMs) from a geological formation in south central Montana known as the J-M Reef and from the recycling of spent catalytic converters. Associated by-product metals at the Company's operations include significant amounts of nickel and copper and minor amounts of gold, silver and rhodium. The J-M Reef is a mineralized zone containing PGMs, which has been traced over a strike length of approximately 28 miles. The Company conducts mining operations at the Stillwater Mine near Nye, Montana and at the East Boulder Mine near Big Timber, Montana. Both mines are located on the J-M Reef. It operates concentrating plants at each mining operation to upgrade mined production to a concentrate form. |
