Unnamed

The Unnamed is a silver and 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 (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Extent of exploration is apparently only the collection of a surface grab sample. Analysis of the float sample yielded up to 7 ppm Ag, 0.9 ppm Au, and 5,000 ppm Cu (Miller and others, 1978).

Comment (Geology): Geologic Description = Float sample of vein quartz contained pyrite, chalcopyrite, and possibly pyrrhotite. Prospect is located at, or near to, a shear zone (possible thrust fault) between upper Paleozoic metavolcaniclastic rocks and Jurassic plutonic and metamorphic rocks. Analysis of the float sample yielded up to 7 ppm Ag, 0.9 ppm Au, and 5,000 ppm Cu (Miller and others, 1978).

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