By 1918 the mine had developed into one of the richest mineral deposits in B.C.. In 1928, a devastating fire nearly closed the mine. Low base metal prices forced a closure in 1953 and although production resumed in 1955 it was sporadic. The property sat idle from 1967-1988 until it was reopened as an open pit mine in 1989 by Westmin Resources.
