HISTORY
Mineral activity in the Coeur d’Alene district began in the mid-1800’s with the discovery of placer gold. Activity was sporadic until 1883, when larger placers were developed and intensive prospecting for lodes began. Lode mining for silver began in 1884. The nucleus of what is now the Galena mine was first developed in 1887. This nuclear holding was gradually expanded by acquisition of several adjacent properties. The mine was successively operated by the Wm. Clark interests from Butte (1887-1916), the Day interests (1917-1920), the Callahan interests (1920-47), ASARCO (1947-1995), Silver Valley Resources, a joint venture of ASARCO and Coeur d’Alene Mines Corporation (1995-1999), Coeur d’Alene Mines Corporation (1999-2006), and U.S. Silver (from June 1, 2006). From 1999 until May 2006, the operating company for the Galena and adjacent properties was named Coeur Silver Valley, Inc.
