A former small underground Pb-Ag-Zn-Cu-Au-Baryte mine located in the center of sec. 16, T.14S., R.4W., 16 miles SE of Ajo. Produced 1881-1965. Owned/operated at times, or in part, by the Carthage Silver Mining Co.; Fernald & Scott; the Gunsight Mining Co.; Butler; Graham & Dickey; and the Fisher Mining Co.
Mineralization is a network of lensing, quartz-calcite-baryte veins with spotty, partly oxidized lead, zinc, and copper minerals along intersecting fissure zones in Laramide granitic rock. The ore zone strikes N25E and dips 55NW.
Workings include shaft and tunnel operations. Prospected as early as the 1870's and reportedly produced some 15,000 tons of $40/T Pb-Ag ore in 1881-1884. Sporadic production of some 120 tons of ore averaging 22% Pb, 5 oz. Ag/T and some Au since 1918, and also possibly in 1936.
