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): Age = Devonian

Comment (Exploration): Status = Active

Comment (Geology): Geologic Description = The bedrock in this area is mapped as Devonian Skajit limestone, dolomite and marble with gray phyllite (Schmidt and Allegro, 1988). This occurrence consists of chalcocite and malachite in bleached limestone. The bedrock is cut by small quartz stringers.

Comment (Reference): Primary Reference = Grybeck, 1977

Comment (Workings): Workings / Exploration = Twenty-five claims were staked in the area in 1966. There was renewed activity in the area in the 1990's by local prospectors who have been mapping and sampling the area (Roy Barr, personal communication, 1997).

Comment (Deposit): Other Comments = Located within the Noatak National Preserve.

Comment (Deposit): Model Name = Sulfide-bearing quartz stringers in Paleozoic limestone.
