Kings River

The Kings River 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 = Jasper, 1965

Comment (Workings): Workings / Exploration = The extent of mineralization is not known (Jasper, 1965).

Comment (Geology): Age = Late Triassic or younger; the mineralization is in limestones within the Early Jurassic to Late Triassic Talkeetna Formation.

Comment (Geology): Geologic Description = Jasper (1965) reports that a prospector noted occasional blebs of malachite and chalcopyrite in and above a Late Triassic(?) unfossiliferous and massive to poorly bedded limestone. Locally the limestone occurs as lenses as much as 30 m thick in shear zones within the Early Jurassic to Late Triassic(?) Talkeetna Formation. The extent of mineralization is not known. When Brooks (1918) first reported this occurrence he reported, based on vague data, that the deposit was similar to the occurrence on Moose Creek (ARDF number AN066).

Comment (Deposit): Other Comments = Location and geologic descriptions in reports are vague.
