A Au-Ag-Cu-Pb (Th, REE) mine located in sec. 24, T4N, R21W, about 5 miles W of Parker Valley in the Dome Rock Mountains. Operated by Haber Inc. (1986).
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. Source mineralization is believed to be Tertiary Au-Quartz-Calcite veins in igneous rocks. The gold in the veins is thought to be very fine and easily transported downstream.
Workings include numerous shafts and tunnels worked from 1860 through 1914, and intermittently through 1940. The placers were worked by dry washing. 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. During the 1984-1986 period, Haber drilled a water well at this site and conducted a limited underground sampling program.
