Alaska Chief

The Alaska Chief is a 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 (Exploration): Status = Inactive

Comment (Geology): Age = Assumed to be related to the development of tin systems in the Lost River area and therefore Late Cretaceous, the age of the tin-mineralizing granites there (Hudson and Arth, 1983).

Comment (Workings): Workings / Exploration = A 35-foot shaft and two exploratory adits were completed early in the century (Knopf, 1908, p. 58-59). One 143-foot long adit intersected 7 feet of low grade galena mineralization 50 feet below the bottom of the shaft. The second adit was 600 feet long and appears to have been driven along a fault zone in limestone without success.

Comment (Reference): Primary Reference = Knopf, 1908 (USGS B 358)

Comment (Deposit): Model Name = Sulfide vein or replacement in limestone. Model not clear; possibly a polymetallic replacement (Cox and Singer, 1986, model 19a)

Comment (Geology): Geologic Description = Gossan with galena remnants in Ordovician limestone; unoxidized character and controls on mineralization are not known.
