The Kizhuyak Lode, North is a copper, gold, and silver 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 (Reference): Primary Reference = Rose and Richter, 1967

Comment (Workings): Workings / Exploration = One sample assayed 0.10 ounce per ton gold and 1.10 ounce per ton silver.

Comment (Deposit): Model Name = Chugach-type low-sulfide gold-quartz veins (Bliss, 1992; model 36a.1).

Comment (Deposit): Other Comments = Site is on land conveyed to the Koniag Corporation.

Comment (Geology): Geologic Description = This occurrence represents the northern end of the Kizhuyak lode. Here the granodiorite on the beach is cut by numerous quartz veins striking N. 15 W. and containing local lenses of pyrrhotite. A sample collected by Rose and Richter assayed 0.10 ounce per ton gold, 1.10 ounce per ton silver, 0.15 percent copper, and trace arsenic. A few hundred feet to the south an area of graywacke inclusions is cut by numerous quartz veins containing minor pyrrhotite and traces of chalcopyrite.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Tertiary
