A former underground Cu-W-Ag-Au-Pb-Zn-Fe-As mine located in the NW¼ sec. 20, T.11N., R.1E. (Battle Flat 7.5 minute topo map), 2 miles NE of the Peck Mine, about 4 miles South of Mayer, at an approximate altitude of 5,800 feet. Ultimately closed in 1922. Owned by the Southwest Metals Co. (1926). Discovered 1890. Produced 1890-1972. Claims extend into the center of the S½ of sec. 20; NE¼, W½W½NW¼, and NE¼NE¼SW¼ of sec. 19; the S½SE¼ of sec. 18; and, the SW¼SW¼ of sec. 17.

Mineralization is a pyritic schist deposit with 7 overlapping lenses of tapering form, most coming to a point 900 feet down from the outcrop. Yavapai chloritic schists strike N.23ºE. at the mine and dip 70ºNW. Orebodies contained in the Yavapai Schist-Taconite and the Iron King Volcanics. Ore control was stratigraphy and igneous activity. Concentration was oxidation at near surface. Alteration included chloritization and sericitization. Gangue is fine-grained quartz.

Workings include a main tunnel 600 feet below the outcrop; a total of 4 tunnels (1928). Production was 180,000 tons of ore averaging 3.75% Cu & 1 oz. Ag/T plus 0.02 oz. Au/T.
