A manganese mine located in central sec. 15, T3N, R21W. Owned by Sandoval & Associates.
Mineralization is irregular, lensing pods and stringers of pyrolusite with unreplaced wall rock and calcite in Mesozoic limestone along a bedding plane fracture.
Workings are comprised of an open pit operation. This mine produced some 150 tons of 44% Mn ore in the mid-1950's.
Mineralization is spotty free gold and auriferous pyrite, with some copper and lead, in a lensing massive quartz vein with iron oxide in a long shear zone cutting Mesozoic quartz-epidote schist. Thorium and REE were noted in this shear zone.
Workings include numerous shafts and tunnels worked from 1860 through 1914, and intermittently through 1940. Total estimated and recorded production for the group would be some 11,000 tons of ore averaging about 0.33 oz Au/T and 0.02 oz. Ag/T.
