A former small underground Cu-Pb-Zn-Ag-Au mine located in the corner intersection of secs. 16, 17, 20 & 21, T.23S., R.20E. (Miller Peak 7.5 minute topo map), in upper Ramsey Canyon, where Pat Scott and Wisconsin Canyon enter Ramsey Canyon, on National Forest land. Produced 1913-1950. Owned at times, or in part, by the Arizona Copper Mining Co.; the Hartford Arizona Copper Mining Co.; and, the Butte & Arizona Mining Co. Operated by the Butte & Arizona Mining Co.; and, the Coronado Investment Co.

Mineralization is a contact metamorphic deposit with irregular veinlets, pods, and disseminations of sulfides in pyrometasomatic tactite in deformed Permian Concha Limestone along a strong fault and intruded by Jurassic quartz monzonite.

Workings include a 200 foot long tunnel driven in the early 1900'S; Three principal adits, including this tunnel, pits, and small prospect drifts. Up to 100 tons of ore were produced intermittently in the early 1900's.
