The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This prospect is on the east valley wall of the Kuskulana River between MacDougal and Berg Creeks. It is at an elevation of about 3,300 feet, 5,100 feet northwest of elevation 5710 and 2,400 feet south-southwest of the center of section 34, T. 3 S., R. 9 E. of the Copper River Meridian. This is locality 131 of MacKevett (1976) and locality 31 of MacKevett and others (1978). It is located to within about 100 feet. Cobb and MacKevett (1980) included this prospect under the name 'Copper Queen'.
Geology: This deposits consists of veinlets and small irregular bodies of magnetite, pyrrhotite, pyrite, and chalcopyrite in faulted, silicified, and garnetized Triassic Chitistone Limestone adjacent to Jurassic granitic rocks (Moffit and Mertie, 1923; MacKevett, 1976). The deposit shows iron-staining and minor copper-staining over a width of 100 feet. It was explored with a 433-foot-long adit and a 50-foot-long crosscut (Moffit and Mertie, 1923; Van Alstine and Black, 1946). Near the portal, the marble contains diopside, garnet, and chlorite.
Workings: The deposit was explored with a 433-foot-long adit and a 50-foot-long crosscut.
Age: The skarn is probably related to a nearby Late Jurassic intrusive body.
Alteration: Calc-silicate replacement of limestone. Oxidation.
Commodities (Major) - Cu; (Minor) - Fe
Development Status: None
Deposit Model: Fe skarn (Cox and Singer, 1986; model 18d)
