A former small surface and underground Ag-Au-Cu-Pb-Zn mine located in central sec. 6, T.23S., R.11E, on National Forest land. Produced 1938-1942. Owned at times, or in part, and, Miller. Operated by G.R. Green (1938).
Mineralization is a lensing quartz-fissure vein with disseminated pyrite and minor base metal sulfides, oxidized and supergene enriched in silver and gold. Some silver chlorides. The wall rock is Jurassic volcanic tuff (Cobre Ridge Tuff).
Workings include open cut, adit and tunnel opertions. Worked sporadically from the 1890's through 1942, producing some 600 tons of ore averaging about 28 oz. Ag/T, 0.2 oz. Au/T and minor Cu & Pb.
