Cub Creek

The Cub Creek 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 = Some prospecting cuts were made in 1964, but there was no mining at that time.

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = Bedrock in the general area of the Cub Creek mine includes syenite of the Late Cretaceous Granite Mountain pluton, and, in the lower portion of the creek, Jurassic-Cretaceous andesite and greenstone. Creek boulders are largely syenite, monzonite, or diorite. The deposit is a gold placer; gold is distributed through 2 feet of gravel overlying bedrock. The gold is fine and flaky and assays $19.20 per ounce (gold at $20.67/ounce) (Harrington, 1919). Concentrates contain a little pyrite and abundant magnetite (Moffit, 1905). Gault and others (1953) found uranothorianite in the placer concentrates on Cub Creek and its headwaters.

Comment (Reference): Primary Reference = Harrington, 1919; Gault and others, 1953

Comment (Commodity): Ore Material = uranothorianite

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

Comment (Deposit): Other Comments = Stream gradient 50 to 75 feet per mile.

Comment (Geology): Age = Quaternary.
