Location: This occurrence is about 2.5 miles west-northwest of the outlet at the south end of Wild Lake. The occurrence is at an elevation of 3,650 feet, about 0.3 mile south-southeast of the center of section 25, T. 31 N., R. 19 W., of the Fairbanks Meridian. The occurrence is the site of sample 130 of Chipp (1972). The location is accurate.
Geology: This occurrence consists of locally mineralized quartz veins in dolomite (Chipp, 1972). A selected sample of quartz with unspecified sulfides and malachite contains 2,100 ppm copper and 2.4 ppm, silver. A second sample of vein quartz, taken approximately 0.2 miles to the north, contains malachite but no elevated metal values. The rocks in the vicinity are Devonian schist and phyllite (Chipp, 1972). No other information is available.
Workings: Only surface sampling.
Alteration: Oxidation of copper mineral(s).
Commodities (Major) - Ag, Cu
