Location: Site is at an elevation of about 5,000 ft. on a ridge approximately 1 1/2 mile west of upper Beaucoup Creek and 6 miles north-northeast of the mouth of Beaucoup Creek (SE1/4 sec. 16, T. 14 S., R. 19 E., of the Umiat Meridian). Location accurate within 1-mile radius
Geology: Visible chalcopyrite and malachite in the remnants of a leached quartz vein in limestone within the Beaucoup Formation (Barker, 1978). Geochemical analysis of a sample of a mineralized quartz-calcite vein crosscutting siltstone and shale of Beaucoup Formation shows anomalous Ag (7 ppm) and Sn (10 ppm) (Cathrall and others, 1977b, sample 75 RR 120). No other descriptive information is available.
Workings: Eight claims located in 1971 by Placid Oil, and exploration was said to be continuing in 1978 (Barker, 1978; Menzie and others, 1985).
