A former small underground Cu-Ag-Au mine located in North-central sec. 1, T.23S., R.15E. Produced 1900-1917. Owned at times, or in part, by Gray; Cooper; and, McCutchen & Hogan.
Mineralization is roughly banded, narrow quartz stringers and veinlets with pyrite and chalcopyrite, oxidized largely to covellite and chalcocite near the surface, in Jurassic granitic intrusive that is strongly silicified and pyritized.
Workings include tunnel, shaft, and adit operations. Worked intermittently from the early 1900's through 1917, producing some 100 tons of selected ore averaging about 20% Cu, 9 oz. Ag/T and 0.2 oz. Au/T.
ROUGHLY BANDED, NARROW QUARTZ STRINGER AND VEINLETS; OXIDIZED TO COVELLITE AND CHALCOCITE NEAR THE SURFACE.
