A former small underground Pb-Ag-Au-Cu mine group located in the NW ¼ sec. 28, and the SE¼NE¼ sec. 29, T.23S., R.14E, 1/2 mile NW of Mt. Benedict (elevation 4565 feet), on private land. Produced 1928-1941. Owned at times, or in part, by Wolfe & Farmer; and, Rawson. Owned and operated by Mr. H.J. Farmer (1939).
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. An associated rock unit is the quartz monzonite of Mount Benedict. Ore concentration was secondary enrichment. Alteration is minor.
Local structures include numerous N-trending aplite dikes with a major fault trending N-S.
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.
