Unnamed (Muck Creek)

The Unnamed (Muck Creek) is a tungsten 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): Geologic Description = The Muck Creek area is underlain by Upper Cretaceous granitic rocks that may contain uranium-bearing minerals (Gault and others, 1953). Two pan-concentrate samples of stream gravels contained 0.125% and 0.16% equivalent uranium. Heavy minerals from the concentrate include garnet, hornblende, augite, sphene, zircon, epidote, apatite, schleeite, powellite, ilmenite, hematite, limonite, magnetite, uranothorianite, and pyrite.

Comment (Geology): Age = Late Cretaceous; Quaternary.

Comment (Commodity): Ore Material = uranothorianite

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

Comment (Deposit): Other Comments = Stream gradient approximately 150 feet per mile.

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Two pan-concentrate samples were collected and analyzed for uranium content by the U.S. Geological Survey (Gault and others, 1953).
