A former Pb-Ag-Zn occurrence/mine located in sec. 21, T10N, R14E, SBM, 0.5 km (0.3 mile) SE of Fountain Peak (coordinates of record, on federal reservation land (Mojave National Preserve/East Mojave National Scenic Area). MRDS database stated accuracy for this location is 500 meters.
Mineralization is hosted in limestone. The ore body strikes N30W and dips 70E at a thickness of 1.83 meters and a width of 15.24 meters. Controls for ore emplacement included fissures. The country rock is limestone from the Birds Spring Formation, comprising thin to thick bedded, gray limestone that forms a long ridge to the N. The W side of the limestone belt is a ridge of Tertiary age dacite. Associated rocks include Late Permian dacite. Local rocks include Permian marine sedimentary rocks, unit 1 (Death Valley and Mojave Desert) and/or Tertiary intrusive rocks (hypabyssal), unit 7 (Northern Mojave Desert).
Workings include surface openings comprised of several shallow, open crosscuts (??). 150 feet below the surface outcrop, a crosscut adit was driven 250 feet W.
Production data are found in: Goodwin, J. G. (1957).
Production information: 250 tons of 15% Pb ore were reported on the dump. The Ag content is about 5 ounces/ton.
