Location: This placer is in the main drainage from Shiels Glacier. The map site is at the midpoint of the placer, which extends for about 2 miles upstream from Nels Miller Slough. It is in the SE1/4 sec. 28, T. 11 S., R. 4 E., of the Copper River Meridian. The location of the site is accurate to within 2000 ft. The occurrence is shown as site P-3 in Jansons and others (1984).
Geology: This occurrence consists of small amounts of placer gold in alluvial and colluvial gravels derived from underlying metasedimentary rocks of the Upper Cretaceous Valdez Group (Nelson and others, 1985). A 0.1-cubic-yard sample assayed 0.0007 oz. Au/cubic yard (Jansons and others, 1984).
Workings: Exploration by industry in 1988 concluded that recent deglaciation and the steep gradient along Shiels Creek preclude the existence of a significant gold placer deposit (Kodosky and Teller, 1989).
Age: Holocene.
Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
