A former underground Ag-Cu-Pb-Cd mine located in sec. 6, T6S, R20E, 1.6 miles SE of Aravaipa on the flank of Imperial Mountain.

Mineralization is a replacement deposit hosted in Horse Mountain volcanics (silicic lava and tuff), and the Bolsa Quartzite. The ore zone strikes NW and dips steeply SW. Small pods of ore occur along a fault zone; mineralized breccia along the Grand Reef Fault. Ore control was fault breccia and the concentration process was replacement.

Area structures include block faulting trending NNW. Regional trends: minor Pre-Cretaceous E- and NE-trending folds and major Post-Cretaceous NNW-trending faults.

Workings are 335.28 meters long and 57.91 meters deep and are comprised of several shafts and adits. No production is recorded. An assay from Ross, 1925, shows Pb from tenths of a percent to 9%; Ag less than 15 oz/ton; Cu 0.14%; in a drift farther south, Ag 0.94-2.42 oz/ton.
