Mineralization is spotty secondary copper minerals in veinlets and coatings, in lensing and banded, coarsely crystalline, quartz-hematite-sericite veins along a fissure zone in Mesozoic granite. Quartz cut by calcite veins and wall rocks silicified and sericitized.
Workings include a shaft(s) and tunnel operations. They were worked intermittently from the early 1910's through 1939. They produced some 145 tons of ore averaging about 2% Cu, 0.3 oz. Au/T and 1.4 oz. Ag/T.
