Stillwater Mining sees 2013 capital expenditures $172.8M Stillwater Mining said its Montana mining operations as currently configured, function well at a production rate of approximately 500,000 combined ounces of palladium and platinum per year. Mine plans for 2013 once again have been structured to achieve that level of production. It is anticipated that total cash cost per ounce for the two Montana mines will average approximately $560 in 2013, 15.7% higher than the $484 per ounce averaged in 2012. Capital expenditures are budgeted to total approximately $172.8M for 2013, up from $116.6M in 2012. The increase is attributable primarily to additional capital requirements at the Marathon project, along with the acceleration of the Far West development area within the Stillwater Mine.
