Location: This occurrence is located on a ridge about 1 mile east of Wild Lake, between the head of Surprise Creek and the north end of Wild Lake. The occurrence is at an elevation of about 3,000 feet in the NE1/4 SE1/4 section 2, T. 31 N., R. 18 W., of the Fairbanks Meridian. Several sample locations (Chipp, 1972, samples 116 and 117; Kurtak and others, 1999, samples 46, 47, and 48) were collected for about 4,000 feet northeast from this occurrence. The location is accurate.
Geology: This occurrence consists of quartz-calcite-ankerite(?) veins with varying amounts of bornite, malachite, or chalcopyrite (Chipp, 1972, sample 116 and 117; Kurtak and others, 1999, sample 46). One of Chipp's samples contains 2,700 ppm copper, 0.14 ppm gold, and 3.1 ppm silver. Sample of quartz veins collected by Kurtak and others (1999, samples 46, 47, and 48 contain copper minerals but analysis of these samples showed no significant metal values. The rocks in the area are Devonian schist and phyllite (Dillon and others, 1986). No other information is available.
Workings: Only surface sampling.
