Glacier Creek

The Glacier Creek is a lead, zinc, copper, silver, and 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 (Reference): Primary Reference = www.grayd.com, 1999

Comment (Workings): Workings / Exploration = At least three holes were drilled in the late 1990's, along with surface mapping and geochemical sampling.

Comment (Geology): Geologic Description = The country rocks at the Glacier Creek prospect are the Lower Mississippian to Middle Devonian Totatlanika Schist, composed predominantly of mafic and felsic metavolcanic and metavolcaniclastic rocks, minor pelitic schist, and fossiliferous marble (Wilson and others, 1998). The deposit consists of stratabound lenses of massive sulfides in strongly altered rhyolite schist (www.grayd.com, 1999). The sulfide minerals are chalcopyrite, galena, sphalerite. The hostrocks and stratabound massive sulfides indicate that the Galcier Creek prospect is a metamorphosed volcanogenic massive sulfide deposit.

Comment (Deposit): Model Name = Kuroko massive sulfide (Cox and Singer, 1986; model 28a)

Comment (Geology): Age = The sulfide minerals probably are syngenetic with their Lower Mississippian to Middle Devonian host rocks.

Comment (Commodity): Gangue = white mica

Comment (Exploration): Status = Active
