|Location and accuracy||This prospect is located on lower Copper Creek, about 2,000 feet upstream of its mouth on the Kotsina River. The map site is at an elevation of about 2,250 feet in the S1/2 section 12, T. 2 S., R. 7 E., of the Copper River Meridian. The prospect is approximately located, to about one-half mile. It is locality 110 of Winkler, Miller, and others (1981[OFR 80-892-B]).|
Geologic descriptionPlacer and lode claims are reported along Copper Creek (U.S. Bureau of Mines 1980; Winkler, Miller, and others, 1981 [OFR 80-892-B]). Several prospects (for example, VA040, VA042, VA043, VA044, and VA045) in the headwaters of Copper Creek are located in proximity to the contact between Triassic Nikolai Greenstone and overlying carbonate rocks (Winkler and others, 1981 [OFR 80-892-A]). The nature of the placers or lodes in lower Copper Creek is not known.
