A small outcrop, mapped by Dillon and Reifenstuhl (1995) as andesite tuff-dacite flow, is located adjacent to the conglomerate unit about 1/2 mile southeast of the Cu occurrence. This occurrence is located within Gates of the Arctic National Park.
Location: This site is at an elevation of about 4,300 feet, on a ridge south of the Hammond River, approximately 6 1/2 miles west-northwest of Sukakpak Mountain and 5 1/2 miles north of Jennie Creek Lake (SW1/4 sec. 3, T. 32 N., R. 11 W., of the Fairbanks Meridian). This site corresponds to unnamed loc. 76 in DeYoung (1978). The location is accurate within a 1-mile radius.
Geology: An occurrence of Cu sulfides and/or malachite-azurite stains is in an area mapped as Middle to Upper Devonian(?) conglomerate in a more extensive unit of black slate, phyllite, and chloritic siltstone (Dillon and Reifenstuhl, 1995). These rocks are all part of the Beaucoup Formation. No other information is available.
