Mineral Products

Pb, Ag, Cu-, Au-, Zn-, U-.5


Geology

Irregular, narrow, shear zones containing spotty argentiferous, oxidized, lead mineralization, largely cerrusite, pyrite, and minor copper, zinc, and gold, cutting Cretaceous quartz latite volcanics. Mineralization fills fissures and partially replaces gouge and breccia. Spotty kasolite, uranophane, autunite, and uranium-bearing pyromorphite recognized. Pyrite gossan5.


Type of Operation and Production

Shaft, adit, and open cut operations. Worked for high silver values prior to 1900 and sporadically from 1925 through 1958. Total production probably some 500 or more tons of ore averaging about 15% Pb, 6 oz. Ag/T and minor Cu and Au. A small amount of picked uranium ore reportedly shipped5.
