Location and accuracy 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).

Geologic setting

Geologic description

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).
Geologic map unit (-144.692016512746, 60.8795038108489)
Mineral deposit model Placer Au (Cox and Singer, 1986; model 39a)
Mineral deposit model number 39a
Age of mineralization Holocene.

Production and reserves

Workings or exploration 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).
Indication of production None
