Itkillik River West

The Itkillik River West is a zinc, silver, barium-barite, and lead 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 (Deposit): Model Name = Pb-Zn quartz veins

Comment (Geology): Geologic Description = Bedrock in the area consists of folded and faulted Hunt Fork Shale that is locally cut by quartz and sulfide-bearing quartz-carbonate veins and veinlets. Cobble-sized pieces of rounded massive white barite, containing streaks and blebs of galena were found as float. The source of the float is unknown. In another gully 800 m to the northeast, lense-like quartz-calcite-siderite veins are confined to a 50 cm-wide zone that trends northwest. The veins contain minor chalcopyrite and trace galena. No zinc minerals were observed.

Comment (Workings): Workings / Exploration = Float of barite-galena cobbles contain up to 62% Ba, 0.67% Pb,and 25 g/tonne Ag. Veins from outcrop contain 735 ppm Cu and 3,900 ppm Zn.

Comment (Reference): Primary Reference = Kurtak and others, 1995, USBM OFR 8-95.

Comment (Exploration): Status = Inactive
