The property was sold to Callahan Mining Company who began milling gold from the Ropes Gold Mine in 1985. Callahan used the pit to dispose of tailings underwater until operations ceased in the early 1990's. The last company to use the Mill was Mineral Processing Corporation, and for over a decade, the Mill sat idle, falling to disrepair.
