A former small underground Ag-Au-Cu-Pb-Zn mine located in North-central (NE¼NW¼) sec. 8 T.22S., R.10E., 3 miles S of Arivaca. Produced 1928-1937. Operated by M.T. Edwards.
Mineralization is oxidized and weathered quartz lenses with free gold and silver chlorides (?) near the surface, and spotty base metal sulfides in depth, along fracture zones in metamorphosed Cretaceous sedimentary formations.
Workings include shaft and tunnel operations. Worked prior to 1900 and intermittently from 1928 to 1940. It produced over 100 tons of ore averaging 4 oz. Au/T, 14 oz. Ag/T, 1.6% Cu and 0.6% Pb.
