A former Au-Cu-Ag-Pb + (Hg - ?) mine located in secs. 21 & 22, T4S, R31E, MDM, 0.5 km (1,700 feet) NNW of Casa Diablo Mountain (coordinates of record), on National Forest land. MRDS database stated accuracy for this location is 10 meters.
Mineralization is hosted in granite. The ore body strikes N55E and dips 65 NW at a thickness of 0.91 meters. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include underground openings comprised of a number of tunnels at different elevations. The main tunnel was driven as a crosscut S30E for 1,000 feet, intersecting the veins. The May Brooks vein was cut 300 feet from the portal. Drifts run 300 feet SW and 75 feet NE. 250 feet of its length was stoped to surface in the SW drift. The Don of Hope vein was encountered 390 feet from the portal and was drifted 300 feet NE, and was stoped for 100 feet. A winze was sunk 250 feet deep on the Don of Hope vein.
Production data are found in: Goodwin (1957).
Production information: The May Brook was the most productive vein. Total production through 1910 was estimated at $50,000 (period values). Work continued through 1922. No other production rrecords were found.
The ore was reported to average $12/ton of Au (period values). 70% of the values reported to be free milling. The remainder of the ore in sulfides (3% of ore).
