Both MRDS files place this mine in sec. 30, T3N, R13E, MDM, but the coordinates in file #10114558 place it in the W½ sec. 31.
Mineralization is a vein deposit hosted in greenstone, phyllite and schist. The ore body strikes NW and dips NE, on the Mother Lode. The hanging wall is greenstone and the footwall is phyllite. There are 3 parallel zones of gold-bearing rock. The ore is comprised of veins and lenses of quartz in slaty, splintery & schistose diabase altered to chloritic and talcose schist. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Workings include underground openings comprised of a shaft and adit. The surface of the property was intermittently prospected.
Production data are found in: Clark, Wm. B. & P.A. Lydon (1962).
No production record was found.
