Mineralization is a vein deposit hosted in amphibolite and schist. The ore body strikes N35W and dips 55NE. A small vein is cut by a N-striking fault dipping 80E, with reverse movement of a few feet. Pyrite was deposited on the fault plane subsequent to movement. Quartz stringers outcrop. Local rocks include undivided pre-Cenozoic metavolcanic rocks, unit 2 (undivided).
Workings include surface & underground openings comprised of a short adit and an open cut.
