A former Cr-asbestos-Fe mine located in sec. 3, T19S, R13E, MDM, 1.3 km (4,100 feet) NNE of Archer Camp, on private land. First produced in 1951. Owned by Mareco Mining Division of Marmac Resources Co., Los Angeles, California. Operated by Keith Jones and John Russell. MRDS database stated accuracy for this location is not stated.
Mineralization is hosted in rocks of the Calaveras Formation, Amador Group (dunite, serpentinite). The ore body is irregular in form with dimensions of 10 meters x 10 meters by 5 meters, and was large enough to account for the mine's total production. The ore body was assumed to have a vertical, pipe-like geometry. Serpentine, in fault contact with surrounding rocks, strikes N72E and dips 60S. The mine is on the SE border of a NW-trending, elliptically-shaped serpentine mass, 19 km by 4 km, along the crest of the Diablo Range. Local alteration was serpentinization. Local rocks include ultramafic rocks, chiefly Mesozoic, unit 3 (Coast Ranges and Western Klamath Mountains).
Workings include surface and underground openings with an overall depth of 25 meters and an overall length of 68.58 meters.
Analytical data results: Lump ore averages 44.5% Cr2O3, 9.1% Fe, Cr:Fe = 3.4. Concentrates average 46.9% Cr2O3, 12.4% Fe, Cr:Fe = 2.6. Milling ore is 11% Cr2O3.
