The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This prospect is at the head of Dan Creek (MacKevett and Smith, 1972). It is at an elevation of about 4,000 feet, 5,100 feet west-northwest of Joshua Green Peak, and 4,000 feet east-southeast of Nikolai Butte. The site is in the SW1/4 of section 6, T. 6 S., R. 17 E. of the Copper River Meridian. This is locality 54 of MacKevett (1976); the location is accurate to within a few hundred feet.
Geology: The deposit at this prospect consists of scattered veins up to 5 centimeters wide that contain chalcocite, pyrrhotite, covellite and malachite along joints in Triassic Nikolai Greenstone (MacKevett, 1976). A sample of the veins contained 30 parts per million (ppm) silver and more than 20,000 ppm copper (MacKevett and Smith, 1968, sample 53). The deposit was explored by a 15-foot-long adit (MacKevett, 1976). Copper mineralization is 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).
