Coeur Rochester Mine (MRDS #10310354) AG, AU

In 1929 it closed down. Approximately $7 million in silver and gold was produced from veins in the Rochester District between 1912 and 1928. The veins are opened in depth by three long adit tunnels. In 1960-69, Silver State Mining Co held the property, and from 1969-1984 ASARCO owned it and drilled 485 holes totalling 160,000 feet.
