A Pb-Ag-Au-Cu mine group located in the NW ¼ sec. 28, T.23S., R.14E. Owned at times, or in part, by Wolfe & Farmer; and, Rawson.
Mineralization is irregular shear zones containing banded lenses of quartz and crushed, sheared, and altered Jurassic quartz monzonite showing partly oxidized and spotty galena, pyrite, and chalcopyrite. Associated with dark lamprophyre dikes.
Workings are shaft, tunnel, adit, pit and open cut operations. Worked sporadically from prior to 1900 to 1941. The group produced some 100 tons of ore averaging about 5% Pb, 5 oz. Ag/T, 0.5 oz. Au/T, and up to 0.9% Cu.
