A former small surface Au-Ag-Pb-Zn-Cu-Graphite mine located in South-central sec. 21, T.14S., R.27E, approximately 2 miles NE of Dos Cabezas, on private land.
Mineralization is auriferous pyrite and minor base metal sulfides in a quartz vein in a fault fissure cutting graphitic Cretaceous shale. Deposit is close to contact of slate with Precambrian quartz monzonite.
Workings are surface openings. Some 600 to 1,000 tons of ore were reportedly produced in the 1880's.
