Glacier Creek

The Glacier 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 (Reference): Primary Reference = Hoekzema and others, 1986

Comment (Geology): Age = Probably no placer in Quaternary gravels.

Comment (Deposit): Model Name = Probably no placer but if so a placer Au deposit (Cox and Singer, 1986; model 39a).

Comment (Production): Production Notes = Probably little or no production.

Comment (Geology): Geologic Description = According to Hoekzema and others (1986), there was prospecting and placer mining on the lower parts of Glacier Creek from 1899 to 1918. As much as a quarter of million dollars was spent developing a placer mine that was probably based on salted samples. No significant production was reported. Glacier Creek is less steep than most of the creeks in the area. Reconnaissance sampling by the U.S. Bureau of Mines found no significant recoverable gold values. Pan concentrate samples contained up to 70% sulfides, mostly pyrite, 10% magnetite, and minor garnet and zircon.

Comment (Workings): Workings / Exploration = Claims were staked on Glacier Creek in 1899 and 1900 but were not developed at that time due to the depth to the pay gravels and the low ore grades (Hoekzema and others, 1986). According to Eakins (1919) the creek was drilled at close intervals for over a mile upstream from the margin of the Klehini River valley and preparations were made to work a 4,200 long section of the lower valley. Dams, flumes, pipelines, giants and hydraulic elevator were installed by midsummer 1915 but operation was prevented by floods that year. There was little production in 1916 due to flooding in late June, 1916 . Hoekzema and others (1986) report that operations continued into 1918 but recovery was poor and the operation closed down after working a quarter mile of stream channel. They also cite a report by Beatty (1937) that indicates that a quarter of million dollars were spent on development that was based on drilling results which later proved to have been salted.

Comment (Exploration): Status = Inactive
