Silver Gold Wikipedia
Galena mine. The Galena mine has a long history dating back to 1887. However, recent mining began in 1953 by ASARCO, in an effort to explore and exploit outcrops of silverlead ore. At that time a shaft was sunk to the 3000 level (3000 feet below the shaft collar) and lateral or level drifts were excavated on the 2800 and 3000 levels.
