Coeur Mine
The Coeur Mine is an underground silver mine located adjacent to the Galena Mine. The Coeur Mine operated until mid-1998 when the property was placed on care and maintenance. There has been no mining activity at the Coeur mine since that time. The Coeur Mine is connected to the Galena Mine, which allows future discoveries at either mine to be developed and processed at either facility. This connection is currently being utilized to provide ventilation and secondary access to the Galena Mine.
The Coeur mine produced continuously from 1969 through 1991 and again from 1996 through 1997. The total production was 39 million ounces of silver and 33 million pounds of copper from 2.4 million tons of ore. Average ore grades were 16.0 ounces per ton silver and 0.68% copper.
This mine is serviced by an operational three compartment shaft with a double drum hoist that goes to 4,000 feet (1,200 m) below the surface. The Coeur mine also has a 600 ton per day flotation mill, maintenance shop, office and dry facility. The Coeur Mill was put back into production in October, 2007 to process lead-silver ores from the Galena Mine. The concentrates produced are shipped to Trail, British Columbia and processed by Teck-Cominco.
