Crowe and others (1992; 1993) and Sainsbury (1993) discuss the genesis of the volcanogenic massive sulfide deposits in this area. The prospect is in the Chugach National Forest.
Location: This prospect is at an elevation of about 900 feet about 1.5 miles east-southeast of the head of Whalen Bay. It is in the SE1/4 sec. 20, T. 12 S., R. 5 W., of the Copper River Meridian. The location is accurate within 1000 ft. This prospect is site C-59 in Jansons and others (1984) and #22 in Cobb (1972: MF-392).
Geology: The country rock at this prospect is graywacke and slate of the Tertiary Orca Group (Nelson and others, 1985). Grant and Higgins (1909) reported a resistant band of nonslaty rock containing irregular stringers and disseminated grains of chalcopyrite and pyrrhotite. The band is up to 12 ft. wide, averages 2-4 feet wide, and is traceable for a 'considerable' distance.
Workings: One adit and surface stripping reported by Grant and Higgins (1909). Site could not be found in the 1980s (Jansons and others, 1984).
Age: Probably Tertiary based on the age of the host rocks.
Commodities (Major) - Cu
Development Status: None
Deposit Model: Besshi massive sulfide (?) (Cox and Singer, 1986; model 24b)
