Unnamed (northeast of Solsmunket Lake)

The Unnamed (northeast of Solsmunket Lake) 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 (Reference): Primary Reference = Miller and Ferrians, 1968

Comment (Workings): Workings / Exploration = Site visited and sampled by U.S. Geological Survey (Miller and Ferrians, 1968).

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = This occurrence consists of a tungsten-bearing quartz vein, and of radioactive minerals, in monzonite (Miller and Ferrians, 1968). The quartz vein is 1 to 3 feet wide. It assayed 7,000 ppm W, but no tungsten mineral was noted. Samples of monzonite from the border facies of the Cretaceous Zane Hills pluton, which is mainly granodiorite, contained 14 to 33 ppm U and 75 to 199 ppm Th. The radioactivity apparently is mainly in uranothorianite, thorite, betafite, allanite, zircon and sphene.

Comment (Commodity): Ore Material = uranothorianite

Comment (Deposit): Model Name = Tungsten-bearing quartz vein and disseminated radioactive minerals in monzonite.

Comment (Geology): Age = Cretaceous.
