The Galena mine has a history dating back to 1887, but modern history and mining commenced in 1953 under the management of ASARCO. Total production has exceeded 160 million ounces of silver, 116 million pounds of copper, and 22 million pounds of lead from 7 million tons of ore. In 1946 ASARCO began work deepening the Galena shaft to the 3000 level, which lead to the discovery of the Silver Vein on the 3000 level and the Galena shaft was extended to its current depth of over 5,500 feet. Over the past 60 years, the Silver vein alone has produced in excess of 100 million ounces of silver and is still in production today. The No. 3 shaft was sunk in the 1960's and is now the principal shaft on the property, operating to a depth of 5800 feet. In 1995, a new joint-venture company was created between ASARCO and Coeur D'Alene Mines Corporation called Silver Valley Resources. This JV included the Coeur and the Caladay Mines. In 1999 Coeur d'Alene Mines Corporation purchased 100% of the assets of Silver Valley Resources and named the operation Coeur Silver Valley. This wholly owned subsidiary was purchased 100% by U.S. Silver Corporation in June 2006, for US $15 million.
