Stillwater Canada, Inc. Announces Voluntary Agreement to Harmonize Environmental Assessment Process

THUNDER BAY, ON--(Marketwire - Apr 15, 2011) - Stillwater Canada, Inc., a wholly-owned subsidiary of Stillwater Mining Company ("Stillwater") (NYSE: SWC), announced today that it has entered into a voluntary agreement (the "Voluntary Agreement") with the Ontario Ministry of Environment to have the Marathon PGM-Copper Project be subject to the Ontario Environmental Assessment Act (EAA).


In the Province of Ontario, ancillary activities associated with the development of a mine, such as establishment of transmission corridors and disposition of Crown lands, are subject to the provincial Environmental Assessment Act (EAA), while private mining development projects that trigger the Federal Environmental Assessment Act are reviewed by the Canadian government. In October 2010, Canada's Environment Minister made the decision to refer assessment of Stillwater's proposed Marathon PGM-Copper Project to an independent Federal Review Panel. Following that decision, Stillwater requested that consideration be given to establishing a joint federal/provincial review panel in order to ensure the continuity and coordination of all assessment activities related to the Marathon project. In moving forward with a voluntary harmonization agreement, Stillwater is hopeful that the harmonized review will reduce duplication and permitting delays while improving the overall process from a consultation and disclosure perspective. This is in keeping with Stillwater's corporate culture of transparency and its proactive approach to environmentally and socially responsible development.

In preparation for the environmental assessment, Stillwater Canada Inc. and its predecessors have gathered extensive baseline information dealing with the natural environment and social and cultural background around the project area. These baseline studies have been underway since 2001 and supplemented and updated further starting in 2007. The baseline program includes research related to climate and meteorology, air quality, noise, geology, soils, wildlife, vegetation, groundwater, surface water, fish and fish habitat, socioeconomics, land use, and cultural and traditional knowledge. Analysis and computer modeling by environmental, engineering and consulting firms are currently underway to assess the cultural and environmental effects of all phases of the mine's life cycle from construction through operation and closure. Additionally, Stillwater Canada Inc. is committed to consulting and working with aboriginal groups, local communities, federal and provincial government representatives and the public-at-large in order to move the project forward in a constructive and proactive manner.
