Location and accuracy This occurrence is near the crest of the mountains between Cooper Creek and the Nabesna River. It is at an elevation of about 6,000 feet, 3,000 feet southwest of peak 7390 and 4,500 feet northwest of peak 7895. The occurrence is about 0.2 mile southeast of the center of section 36, T. 7 N., R. 14 E. of the Copper River Meridian. This is locality 15 of Richter and others (1975) and National Park Service locality WRST-18 (unpublished data). Cobb and Richter (1980) included this occurrence under the name 'Camp Cr.'. It is located to within a few hundred feet.

Geologic setting

Geologic description

A chalcocite vein, 6 inches to 2 feet wide, cuts amygdaloidal basalt of the Triassic, Nikolai Greenstone here; a sample assayed 61 percent copper (Mendenhall and Schrader, 1903). Nikolai Greenstone makes up most of the bedrock in the headwaters of Camp Creek (Richter, 1971 [I-656], 1976). Copper mineralization is locally common in Nikolai Greenstone and is thought to have accompanied regional deformation and low-grade metamorphism in the Late Jurassic to Early Cretaceous (MacKevett and others, 1997).

Age of mineralization Cretaceous? Alteration and copper mineralization in the Nikolai Greenstone is thought to have accompanied regional deformation and low-grade metamorphism in the Late Jurassic to Early Cretaceous (MacKevett and others, 1997).
