See also Hogan Hill (GU008).
Location: This occurrence (Cobb, 1979 [OF 79-1247]) is east of the Richardson Highway on the upper reaches of Haggard Creek, about 2.0 miles north-northeast of Hogan Hill (GU008). It is the same locality reported as number 2 by Rose and Sanders (1965, p.14), Mulligan (1974), Richter and Matson (1972), and MacKevett and Holloway (1977). The occurrence is in the SW1/4SE1/4, section 32, T. 11 N., R. 1 W., Copper River Meridian.
Geology: Pyrite and traces of chalcopyrite occur on fracture surfaces in a late Jurassic(?) granodiorite pluton which is part of the Gulkana River metamorphic complex (Rose and Saunders, 1965; Berg and Cobb, 1967; and Nokleberg and others, 1994).
Workings: There are old gold prospect pits in the general area but no data on the actual presence of gold (Mulligan, 1974).
Age: Mineralization is related to granodiorite which is probably Late Jurassic.
Alteration: K-feldspar and propylitic (chlorite) alteration of granodiorite adjacent to mineralized fractures (Rose and Saunders, 1965).
