A former small surface and underground Au-Pb-Ag-Cu mine located in East-central sec. 29, T.23S., R.14E, 4 miles N of Nogales, on private land. Produced 1880-1915. Owned by the Old Dominion Mining & Reduction Co.
Mineralization is irregular shear veins containing spotty, largely oxidized, auriferous and argentiferous lead and minor copper mineralization in roughly banded quartz and brecciated Jurassic quartz monzonite wall rock. Associated lamprophyre and diorite dikes.
Workings include shallow shaft and tunnel operations. Worked sporadically from the mid-1800's to 1915. The production would be some 100 tons of ore averaging about 0.8 oz. Au/T, 4% Pb, 4 oz. Ag/T and minor Cu.
