A former Au-Ag-Pb-Bi-Cu-Sb-As occurrence/mine located in sec. 11, T1S, R12E, SBM, 3.5 km (2.2 miles) NNE of New Dale, on private (patented) and federal land. The property is comprised of 8 claims, 4 of which are patented. Operated during the period 1936-1939 by the Carlyle Mining Corporation and during the period 1940 by Camco Mining Company. Last operated in 1941. MRDS database stated accuracy for this location is 10 meters. Detailed descriptions of the workings and ore treatment in the milling plant, see Tucker and Sampson (1943).
Mineralization is hosted in granodiorite and diorite. The ore body is shoots in form, strikes N15E and dips 75W at a thickness of 1.83 meters. Controls for ore emplacement included a fault fissure. The vein is 6 to 12 feet thick along a fault. The ore shoot is 6 feet thick. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).
Workings include underground openings comprised of a 1,200 foot adit driven S along thge vein. 5 ore shoots were encountered. One is 100 feet long and 6 feet thick and was stoped to surface, a maximum height of 200 feet. Raises were also driven to surface at 480 feet and 580 feet from the adit portal. A winze was sunk 680 feet from the portal with 200 feet and 250 feet of drifts at the 30 foot and 80 foot levels, respectively.
Production data are found in: Wright (1953).
Production statistics: Year: 1939 (period = 1936-1939) ore mined: 13,046.55 metric tons. Grade (estimated): ^Au, Ag and Pb from 13,256 tons of ore. No other production record was found.
Analytical data results: average of $12 (period values) per ton in Au from an ore shoot 60 feet long and 6 feet thick. Au values on the hanging wall and high-grade Ag ore reported on the footwall. The mill was erected sometime after 1915. Values in Au, Ag & Pb by means of a jig, flotation cells and a concentrating table. Mill heads reported to carry $10-$20 (period values) Au/ton & $3-$6 (period values) Ag/ton.
