The Slope Creek is a gold 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 (Workings): Workings / Exploration = Type of workings: surface

Comment (Reference): Primary Reference = Moffit, 1944, USGS B 943-B

Comment (Deposit): Model Name = Placer

Comment (Deposit): Other Comments = Some confusion exists in the literature in distinguishing between Slope Cr. and Boulder Cr. It is likely that most data probably refers to both. The mine symbol for Boulder Cr. on fig. 5 of ADGGS GR 21 is in the Gulkana quad.

Comment (Geology): Geologic Description = No data on size or grade of deposit, but it was probably very small; placer deposits probably associated with mafic diorite-quartz diorite complex

Comment (Commodity): Ore Material = unknown Bi mineral)

Comment (Commodity): Gangue = In concentrates: magnetite

Comment (Commodity): Ore Material = unknown Bi mineral

Comment (Exploration): Status = Inactive
