A former small Pb-Zn mine/group of claims located in sec. 23, T11S, R8E.
Mineralization is ore along fractures in granodiorite porphyry. Galena, sphalerite, chalcopyrite, and pyrite sulfides were observed in dump material. Much pyrite-limonite on surface with moderate to heavy propylitic alteration.
Workings include shafts, winzes, drifts, prospect pits, short adits, and crosscuts. Group of 2 major adits, several minor adits + prospects. The deepest adit is 300 feet (91.44 meters) long. 2 carloads of ore were shipped.
