Location: The Copper Creek occurrence is about 4.9 miles east-southeast of the creek mouth on the Charley River. It is in section 4, T. 1 S., R. 22 E., of the Fairbanks Meridian. The location is accurate within 1,000 feet. The Copper Creek occurrence is within the Yukon-Charley Rivers National Preserve. The Copper Creek prospect is locality 16 of Cobb (1972 [MF-393]) and locality 18 of Eberlein and others (1977).
Geology: The rocks along Copper Creek are Paleozoic schist, marble and amphibolite that are interpreted to be a roof pendant several square miles in aera on the margin of the Charley River batholith of Tertiary to Mesozoic age (Wedow and others, 1954; Foster, 1976). Quaternary terrace gravel deposits are extensive along the south side of Copper Creek. The Copper Creek occurrence was examined by the U.S. Geological Survey in 1949 during a regional reconnaissance for radioactive deposits (Wedow and others, 1954). Placer concentrates taken about 100 feet upstream of the Copper Creek lode prospect (EA002) are slightly radioactive, and contain thorium and trace monazite. Minor radioactivity is associated with copper mineralization at the Copper Creek lode prospect (EA002) (Wedow and others, 1954).
Workings: The Copper Creek occurrence was examined by the U.S. Geological Survey in 1949 during a regional reconnaissance for radioactive deposits (Wedow and others, 1954).
