Mineralization is a vein deposit. The vein is in the form of lenses, one 40 feet wide by 20 inches average thickness; another, 120 feet from the first lens, is 55 feet wide with a thickness of 2 feet. Both vein walls appear to be gabbro. Quartz includes minerals and brecciated country rock. Another vein to the W strikes N83E with a thickness of 1½ to 2 feet. Local rocks include Mesozoic gabbroic rocks, unit 2 (undivided).

Workings include underground openings comprised of an inclined shaft reported to extend down 220 feet with levels at 60, 120 & 220 feet. The 60 foot level is caved. The 120 foot level was extended 300 feet in 1938.

Production data are found in: Clark, Wm. B. & D.W. Carlson (1956).

A small amount of Au was produced in 1895.
