A former underground Au-Ag-Cu-Pb (Th, REE) mine group located in the SE¼ sec. 23 to the NW¼ sec. 25, and SE¼ sec. 23, T4N, R21W, 8 miles W of Quartzsite. Owned at times, or in part, by Scott; and, the Scott Lode Mines, Inc.
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. Vein has cavities. In the oxidized zone, these cavities are more or less filled with iron oxide that contains visible free gold. Where oxidation has not been complete, gold-bearing pyrite is relatively abundant, particularly near the walls of the vein. Thorium and REE were noted in this shear zone.
Workings include numerous shafts and tunnels. Several shafts are inclined with interconnecting tunnels. Worked from 1860 through 1914, and intermittently through 1940. Total estimated and recorded production would be some 11,000 tons of ore averaging about 0.33 oz Au/T and 0.02 oz. Ag/T. No copper or lead recovered.
