Denali Bench

The Denali Bench 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 (Geology): Age = Quaternary.

Comment (Exploration): Status = Inactive

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

Comment (Reference): Primary Reference = Smith, 1971

Comment (Reserve-Resource): Reserves = There is a large resource of sub-economic gold-bearing gravels.

Comment (Workings): Workings / Exploration = Small-scale mechanical and hydraulic operations have tested the tenor of the exposed gravels. Some drilling has been completed on portions of the bench gravels.

Comment (Geology): Geologic Description = The Denali Bench gravels, as defined by Smith (1971), are on the south side of Valdez Creek upstream from the Dry Creek Cut (HE195). The gravels occur both on the bedrock bench and in a paleochannel. The paleochannel contains large, rounded boulders; it grades upwards into well-bedded fluvial gravels. All lithologies in the gravels appear to have been derived from within the Valdez Creek valley.
