A former Pb-Ag-Zn-Au-Cu mine located in secs. 11, 12, 13 & 14, T16S, R38E, MDM, 0.2 km (0.1 miles) ENE of Cerro Gordo (8 miles E of Keeler). Operated during the period 1909 to 1937. MRDS database stated accuracy for this location is 10 meters.
Mineralization is a vein deposit with 3 parallel veins 1 to 3 feet thick, hosted in limestone. The ore body strikes N30W and dips 70W at a thickness of 0.91 meters. Limestone with a belt of slates occurs on the W slope of the ridge. Diorite porphyry intrusions occur in the limestone, trending NW on the Lead King and Lead Prince claims. The E slope of the ridge is a belt of white marble 300 feet wide. Associated rocks include the diorite. Local rocks include Paleozoic marine rocks, undivided, unit 1 (Mojave Desert and Death Valley area) and/or Carboniferous marine rocks, unit 3 (SE California Clastic Assemblage).
Local geologic structures include: a fault which strikes N and dips 70W.
Workings include underground openings with a length of 320.04 meters and an overall depth of 60.96 meters, and comprised of a 200 foot shaft, 800 feet of drifts and a 50 foot winze on the 200 level.
Total production: $30,000 in Pb, Zn, Ag, Au & Cu (period values). The Pb ore shipped carried 20 to 29% Pb and 26 ounces Ag/ton. It was stated that 46,000 pounds of Zn ore was shipped, averaging 39.2% Zn.
