Unnamed

The Unnamed is a copper 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 = Extent of exploration is apparently only the collection of a surface grab sample. Analysis of the float sample yielded 1,500 ppm Cu and less than 10 ppm Sn (Miller and others, 1978).

Comment (Geology): Geologic Description = Float sample of vein quartz contained pyrite and malachite staining. Bedrock is Tertiary volcanic rocks, felsic and mafic subaerial volcanic rocks and related shallow intrusions. Nearby, at a lower elevation, is a Jurassic plutonic and metamorphic unit consisting of mainly quartz diorite, granodiorite, amphibolite, and greenschist. Analysis of the float sample yielded 1,500 ppm Cu and less than 10 ppm Sn (Miller and others, 1978).

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Probably Tertiary or younger, quartz vein cuts Tertiary volcanic rocks .

Comment (Reference): Primary Reference = Miller and others, 1978
