Mineralization is a Mn deposit. The ore body is 0.61 meters wide and 15.24 meters long. Disseminated Mn oxide in white chert is exposed for 50 feet, with a maximum width of 2 feet. It is displaced by several faults. On the N side, the ore body lies almost parallel to the ground, dipping 15N, but on the S side it is folded into a sharp anticline. The footwall is shaly chert and the hanging wall is thin-bedded brown chert. The footwall exposure contains 4 feet of low-grade ore. Local rocks include the Franciscan melange.
Workings include surface operations.
Analytical data: Average grade 35% Mn.
