A former lode Au mine located in the NE¼ sec. 5, T2N, R13E, and in secs. 31 & 32, T3N, R13E, MDM, about 2.65 km (1½ miles) SW of Angels Camp, along Greenhorn Creek, on private land. MRDS database stated accuracy for this location is 100 meters.
Mineralization is a vein deposit hosted in schist and diabase. The ore body strikes NW and dips NE at a thickness of 15.24 meters. The vein is 40 to 50 feet thick and lies on the Mother Lode. The ore is comprised of veins and lenses of quartz in slaty, splintery and schistose diabase. The diabase is altered to chloritic and talcose schists. Reticulated systems of small quartz veins are quite common. Local rocks include Jurassic marine rocks, unit 1 (Western Sierra Nevada and Western Klamath Mountains).
Workings include underground openings comprised of an adit and shafts.
Production data are found in: Clark, Wm. B. & P.A. Lydon (1962).
