A former lode Au mine located in sec. 17, T6N, R13E, MDM, about 4 km SW of West Point, on the divide between the Middle Fork and South Fork Mokelumne River (1½ miles NE of Glencoe). MRDS database stated accuracy for this location is 500 meters.
Mineralization is a vein deposit hosted in granodiorite and slate. The ore body strikes N20E and dips 30SE at a thickness of 0.91 meter. The vein hanging wall is granodiorite and the footwall is slate, with the vein on the contact between the two. 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 2 adits, one at 1,700 feet of altitude and 600 feet long with 540 feet of drifts and crosscuts; the other at 1,900 feet of altitude and 100 feet in length.
