The Unnamed (below Shiels Glacier) is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Workings): Workings / 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).

Comment (Geology): Age = Holocene.

Comment (Reference): Primary Reference = Jansons and others, 1984

Comment (Geology): 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).

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Deposit): Other Comments = Chugach Alaska Corporation, Anchorage, Alaska has control of these lands.

Comment (Exploration): Status = Inactive
