A former lode Au mine located in secs. 12 & 14, T6S, R17E, MDM, 3.1 km (2.0 miles) ESE of Catheys Valley. Operated by Bobbie Mining Co. (1922-1923). MRDS database stated accuracy for this location is 1,000 meters.
Mineralization is a vein deposit with 3 parallel veins, hosted in diorite. The principal vein was reported to contain an ore shoot about 9 feet wide and 200 feet long. The ore is a heavy sulphide. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include underground openings with a length of 365.76 meters, and comprised of a 1,200 foot tunnel, which gave no great depth on the vein.
The principal vein has an average of $12.00 per ton (period values). Mill operations ceased in 1923 and has since been removed. Idle.
