A surface Au-Cu prospect located in the center NΒ½ sec. 33, T2S, R15W, on federal land. (Engesser Pass 15 minute topo map), 2 miles E of the Engessor Mine, in the NW Tank Mountains.
Mineralization is a small area of fissured granitic rock that emerges from beneath the lavas that make up the surrounding, rugged mass of the range. Ore is in narrow quartz-carbonate veins/stringers. Vein walls somewhat sericitized and silicified. The ore zone is 1.22 meters wide. Ore control was quartz-carbonate stringers in fine-grained granite. Tectonic influences include block faulting. Associated rock unit is the Kofa volcanics.
The granite has been deeply decayed so that its exposures now consist of quartz, chlorite, and kaolinized feldspar. The quartz, which is of yellowish-white colour, is locally honeycombed and contains many small bunches of brown to black iron oxide.
Workings comprise two shafts at 15 and 30 feet (9.14 meters) deep; and a shallow cut. No production record.
