A small former surface and underground Pb-Ag-Zn-Au-Fe mine located in the NE¼ sec. 31, T4S, R22W, a short distance N of the Colorado River, on federal land. Started about 1875. Owned at times, or in part, by Selby; Ferguson; Sentenac Mines Co.; Riverview Mines Co.; and, Rocher.
Mineralization is pockety ore shoots of lead and zinc carbonates with scattered bunches and narrow veins of galena and iron-rich sphalerite in a gangue of iron oxides, manganiferous to ferruginous calcite, brecciated wall rock, and gouge in lensing fault zone veins cutting metamorphic Mesozoic schist. The ore zone strikes N70E and dips 40NW. Vein walls show pyrite metacrysts and pronounced silicification and chloritization. An associated rock unit is granite.
Workings include shaft, several hundred feet of tunnels, a few shallow winzes, small stopes, and numerous open cuts operations. This mine was worked intermittently since about 1875. Total estimated and recorded production would be some 150 tons of ore averaging about 14% Pb, 6 oz. Ag/T, 8% Zn, and 0.2 oz. Au/T.
