A former underground Zn-Pb-Cu-Ag-Au-Mn mine located in East-central sec. 3 & West-central sec. 2, T24S, R16E (protracted). Owned at times, or in part, by the Duquesne Mining & Reduction Co.; Callahan Zinc Lead Co.; Nash Mines; and Marland.
Mineralization is bunchy and disseminated sulfides in pyrometasomatized lenses in Permian Naco Group limestone along a nose of strong garnetization. Mineralization is controlled by bedding and faulting.
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. This mine was worked sporadically in the 1940's & 1950's. It produced some 20,000 tons of ore averaging about 8% Zn, 3% Pb, 1.5% Cu, 5 oz. Ag/T and minor Au.
