The Unnamed (south of Inland Lake) is a uranium and thorium 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 (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = The site was visited briefly and sampled by U.S. Bureau of Mines in 1984.
Comment (Geology): Age = Cretaceous.
Comment (Geology): Geologic Description = The country rocks in the area of this occurrence consist of the Cretaceous Inland Lake alkaline intrusive complex. The occurrence consists of locally abundant purple fluorite as matrix and breccia filling in syenite rubble. The fluorite is similar to that associated with the radioactive zones near VAMB Saturday at the Uranium 2 and 3 occurrences (ARDF number SE005 and SE006) (Barker, 1985). A sample of fluorite-bearing pulaskite, possibly a dike, from the Inland Lake alkaline complex contained 31 ppm U and 178 ppm Th, but no radioactive minerals or alteration zones were identified.
Comment (Reference): Primary Reference = Miller and Bunker, 1975
Comment (Deposit): Model Name = Radioactive minerals in fluorite-bearing pulaskite.
Comment (Deposit): Other Comments = the occurrence is located within the Selawik National Wildlife Refuge.
Comment (Commodity): Ore Material = Radioactive minerals
