The Company conducts mining operations at its Stillwater and East Boulder mines in south-central Montana. Concentrating plants are located at both mines to upgrade the ore to a concentrate. The Company also operates a smelter, refinery and laboratory at our metallurgical complex in Columbus, Montana, to further upgrade the concentrate to a PGM-rich filter cake. Another key segment of the Company’s operations is the recycling of spent catalyst material to recover PGMs.

Two major projects — Blitz and Graham Creek — were announced in 2010. The Graham Creek project at the East Boulder Mine was completed during 2014, ahead of schedule. The Blitz development project, at the Stillwater Mine, is currently in progress.

The Company owns the Marathon PGM-copper deposit in Ontario, Canada. In addition, the Company owns the Altar porphyry copper-gold deposit located in the San Juan province of Argentina.
