Comments

Comment (Exploration): Status = Probably inactive

Comment (Deposit): Other Comments = These occurrences are within one mile of the Alaska, Chilkat Bald Eagle Preserve.

Comment (Geology): Age = Cretaceous or younger based on age of the Klukwan ultramafic complex (MacKevett and others, 1974).

Comment (Reference): Primary Reference = Still and others, 1991

Comment (Deposit): Model Name = Only an occurrence with little information; it appears to be primary copper sulfides in the outer dioritic phase of a zoned ultramafic complex, with secondary copper minerals along joints (Cox and Singer, 1986; model 9).

Comment (Geology): Geologic Description = The following information is summarized from Gilbert and others (1991). Several float and bedrock samples at this site were collected from two steep drainages and along or near the ridgetop between the two drainages. The samples are mostly diorite, granodiorite and hornblende diorite with both primary and secondary copper minerals. The secondary copper minerals often occur as coatings along fractures. Samples contain up to 38,400 ppm copper, 18.90 ppm silver, and 2.43 ppm gold. The samples were collected about 3.4 miles southeast of the center of the Cretaceous, Klukwan zoned-ultramafic complex(SK030). The samples come from the outer dioritic phase of the zoned complex (Gilbert and others, 1987; MacKevett and others; 1974).
