A Pb-Ag-Cu-Zn-Au mine located in T.21S., R.15E. Owned at times, or in part, by Mansfield & Ryan; the Gunsight Mining Co.; Powers; Mansfield Mining & Smelting Co.; Pierce; Laycock; and, Bradsher.
Mineralization is a cluster of roughly parallel quartz-fissure veins containing sulfides and sulfosalts in a quartz-calcite & barite and manganese gangue. The wall rocks are strongly altered Triassic dacitic and latitic flows and Cretaceous andesite breccia intruded by Laramide quartz latite dikes, stocks, sills, and breccia.
Workings include tunnel and shaft operations. Worked intermittently from 1879 through 1951. The group produced some 370 tons of ore averaging about 19% Pb, 22 oz. Ag/T, 2% Cu, and 0.1 oz. Au/T.
