A former Pb-Ag-Au-Cu occurrence/mine located in the N½NE¼ sec. 17, T6N, R4W, SBM, 1.7 km (1.1 miles) NE of Oro Grande. MRDS database stated accuracy for this location is 1,000 meters.
NOTE: USGS MRDS database file #10034026 presents MRDS file #10116561 as a related file. This latter file pertains to another "Carbonate" mine.
Mineralization is a vein deposit hosted in limestone. The ore body is irregular in form at a thickness of 0.61 meter. Controls for ore emplacement included a shear zone. The formation that encloses the veins trends NE and dips not exceeding 20 degrees (at the main workings). The 2 veins are formed at the contact between massive blue limestone and mica schist, in a shear zone ½ mile long. The schist is 1 to 4 feet thick. At various points along the workings is a light-colored, decomposed rock resembling a felsite. Associated rocks include felsic volcanic rocks. Local rocks include Carboniferous marine rocks, unit 1 (Western Mojave Desert).
Local structures include a fault.
Workings include underground openings with an overall depth of 30.48 meters and comprised of a 225 foot shaft plus several shallow shafts.
Production data are found in: Goodwin, J.G. (1957): 622.
Recorded production during the period 1891 to 1940 was intermittent. Substantial amounts of Cu and Au were recovered in addition to Pb and Ag.
