Quartz King Mine; Copper Top Mine
A former surface and/or underground Cu-Au-Ag mine located in the SE¼ sec. 26 , T10N, R19W, on land of unknown status. Owned at times, or in part, by the Quartz King Gold Mining Co.; Rio Vista Mines; and Osborne & Botsum. Owned and operated by Mr. Huffman (1956). NOTE: Widely varying alternate coordinates provided: 34.1775N, 114.1997W.
Mineralization is spotty ore shoots of copper carbonates and silicate with hematite in a brecciated rock and quartz gangue along parallel, vein-like bodies in a nearly vertical, wide shear zone in folded, metamorphosed Paleozoic-Mesozoic sediments, along an anticline close to a thrust fault zone. Some diabase dike intrusions are present.
Workings include shaft and tunnel openings. This mine was prospected and worked intermittently from the early 1900's to the 1950's, producing some 100 or more tons of ore averaging about 8% Cu, 0.4 ounce Au/ton and 0.1 ounce Ag/ton.
