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 = Sphalerite-bearing concretions contain up to 200 ppm As, more than 20 % Fe, and 500 ppm Zn.
Comment (Reference): Primary Reference = Kelley and Mull, 1995, MF-2225-A;
Comment (Deposit): Model Name = Sediment-hosted Pb-Zn
Comment (Geology): Geologic Description = Pyrite nodules up to 10 cm in diameter with cores of sphalerite occur as float in stream. Outcrops south of the Ivotuk Hills near this site consist of shale and chert of Permian to Jurassic age.
