The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This occurrence is on the southwest flank of Granite Peak. It is at an elevation of about 6,200 feet, 1,400 feet south-southwest of Granite Peak, and 2,300 feet northeast of the center of section 36, T. 1 S., R. 8 E. of the Copper River Meridian. This is locality 178 of MacKevett (1976) and locality 3 of MacKevett and others (1978). The location is accurate to within about 100 feet.
Geology: This occurrence consists of numerous pyrite- and chalcopyrite-bearing quartz veinlets and sulfide disseminations in Jurassic granodiorite (MacKevett, 1976). Samples of the mineralization contain as much as 0.1 part per million (ppm) gold, 2 ppm silver, 5,000 ppm copper, 70 ppm molybdenum, more than 5,000 ppm barium, and 100 ppm antimony.
Workings: Only limited surface sampling.
Age: Jurassic or younger based on the age of the granodiorite host rock.
Alteration: The type of alteration is not specified.
Commodities (Major) - Cu; (Minor) - Ag, Au, Ba, Mo
Development Status: None
Deposit Model: Porphyry Cu (Cox and Singer, 1986; model 17)
