A former underground W-Pb-Mo-Au-Ag-Cu mine group located on 6 unpatented lode claims in sec. 11, T7S, R14E, about 1¼ miles (½ mile per MRDS ? - not supported by coordinates) SSW of Antelope Peak, and about 3¼ miles due E of Barkerville, and about 11½ miles SW of Winkleman, on private land. Discovered in 1925 by C.B. Upshaw, G.E. Upshaw, and Robert Gill.
Mineralization is a tabular ore body comprised of quartz veins which contain sporadic ore minerals, hosted in granite. The ore zone is 76.2 meters long and 0.41 meters thick, strikes N70E, and dips vertically. Ore control was quartz veinlets. Associated rock unit is the Ruin (Oracle) Granite. Area structures include NNW-trending block faulting.
Workings include a 75 foot (22.86 meters) inclined shaft, 25 and 18 foot vertical shafts, a 25 foot adit, 50 feet of drifting, and 10 shallow open cuts.
