The Granite 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 (Reference): Primary Reference = Hoare and Cobb, 1977

Comment (Workings): Workings / Exploration = Placer mine tailings from open-cut operations are present along about 3/4 mile of lower Granite Creek.

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

Comment (Geology): Geologic Description = About 3/4 mile of lower Granite Creek has been placer mined for gold. Most of the Granite Creek drainage is within a mid-Cretaceous granitic pluton but the lower part crosses the contact with hornfels in Jurassic volcanic rocks (Box and others, 1993). Mining took place in 1938-1940 and in 1946 but additional information about the placer deposit is not available (Hoare and Cobb, 1977).

Comment (Geology): Age = Quaternary.
