Lafayette Glacier

The Lafayette Glacier is a 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 (Production): Production Notes = No recorded production.

Comment (Reference): Primary Reference = Jansons and others, 1984

Comment (Workings): Workings / Exploration = There have been no placer workings or production to date and potential for mineral development is low (Jansons and others, 1984). An alluvium sample contained 0.001 oz/cubic yard Au. Two float samples contained a trace of gold and 0.03 and 0.12 oz/ton Ag.

Comment (Geology): Geologic Description = Jansons and others (1984) reported disseminated, very fine-grained gold in poorly washed fluvial glacial gravels. A large volume of gravel occurs in the stream flowing from Lafayette Glacier and large boulders are present. The bedrock in the area is metasedimentary rocks of the Late Cretaceous Valdez Group. Quartz vein material and metasedimentary float rock contain pyrite, a trace of gold, and up to 0.12 oz/ton Ag (Jansons and others, 1984).

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Quaternary
