The Imelyak River is a barium-barite, copper, lead, and zinc 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.

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 (Reference): Primary Reference = Mayfield and Grybeck, 1978
Comment (Deposit): Other Comments = Located on land within the Noatak National Preserve.
Comment (Geology): Geologic Description = Sphalerite and galena in shear zone less than 3 ft. (1 m) wide in limestone; and malachite, azurite, and barite vein less than 6 ft. (2 m) wide cutting limestone. Occurrence may be related to other sedimentary rock-hosted mineral occurrences in the Brooks Range; see for example Schmidt (1997, p.35-65) and Schmidt and Werdon (1993, p. 143).
Comment (Deposit): Model Name = Polymetallic vein? (see Schmidt and Werdon, 1993, p. 143)
Comment (Exploration): Status = Inactive
