A former underground Zn-Pb-Cu-Ag-Au mine located in the center of sec. 2, T24S, R16E (protracted), on private land. Owned at times, or in part, by the Duquesne Mining & Reduction Co.; Callahan Zinc Lead Co.; Nash Mines; Amado; and, Granillo.
Mineralization is base metal sulfides in irregular deposits in Permian Naco Group limestone along a strong fault zone between limestone and Jurassic-Triassic volcanics. Pyrometasomatic mineralization.
Mineral deposits of the Washington-Duquesne area occupy a limestone-sediment belt (2.5 miles long by 1.25 miles wide) surrounded by igneous rocks which also form detached masses and dikes within the belt.
Workings include shaft operations. Mined mainly from 1940 through 1963, producing a total of some 21,000 tons of ore averaging about 9% Zn, 2% Pb, 2% Cu, 4 oz. Ag/T and minor Au.
