This was predominantly a Zinc Mine and is now the home of the World Museum of Mining. The mine opened in 1875 and was abandoned in 1956. At one time it was one of the largest zinc producers in the NW and was shipping 600 tons of ore daily. The original shaft was an incline, and the current shaft accessed by the museum was sunk in 1922.
