Kivivik

The Kivivik 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 (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Schmidt and Allegro, 1988

Comment (Geology): Age = Jurassic

Comment (Commodity): Gangue = iron oxides

Comment (Geology): Geologic Description = At the occurrence, basalts of probable Jurassic age contain both disseminated chalcopyrite and pyrite, and pyrite and epidote in vesicles. A 30- by 40-meter area of red-orange-stained, pillow basalt contains pyrite, minor chalcopyrite and ochre. Magnetite occurs in the sediment of the stream draining this occurrence. A sample of pyrite contained 120 ppm Zn, 1 ppm Ag, 50 ppm Co, 300 ppm Cu, and 1000 ppm Mn. A sample from a heavily stained area contained 150 ppm Cu and 1000 ppm Mn. An ochre sample contained 110 ppm Zn and 200 ppm Cu. A sample of pyrite and epidote in vesicles contained 20 ppm As, 0.5 ppm Ag, and 1500 ppm Mn. A sample of chalcopyrite and pyrite in basalt contained 2 ppm Ag, 50 ppm Co and 500 ppm Cu (Schmidt and Allegro, 1988).

Comment (Deposit): Model Name = Basaltic copper (Cox and Singer, 1986; model 23).

Comment (Deposit): Other Comments = Located in the Noatak Wilderness.

Comment (Workings): Workings / Exploration = Area was visited and sampled by the U.S. Geological Survey (Schmidt and Allegro, 1988).
