Mint

The Mint is a copper, gold, silver, 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 = Porphyry Cu-Au or polymetallic vein? (Cox and Singer, 1986; model 20c, or 22c?)

Comment (Geology): Geologic Description = Host rocks are andesite, argillite, and graywacke. Age of sedimentary host rock is Cretaceous-Tertiary, age of associated igneous rock is Tertiary. Mineralization consists of quartz-sulfide veinlets and stockworks in brecciated argillite and graywacke that are cut by altered andesite dike; veinlets also in dike.

Comment (Reference): Primary Reference = Richter, 1963

Comment (Workings): Workings / Exploration = Two short tunnels and an open cut yielded up to 270 ppm Ag, 3 ppm Au in rock analyses (Kurtak and others, 1992)

Comment (Exploration): Status = Inactive
