Gilmore Creek

The Gilmore 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 (Production): Production Notes = No quantitative information is available, but there was obviously production during the more than 90 years the creek has been placer mined.

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

Comment (Geology): Geologic Description = Gold, some with intergrown native bismuth, was found before 1906 on bedrock. The gravel was a few feet thick near the head of the creek and as much as 60 feet thick near the mouth. Gravel in the creek is mainly schist, quartz, and granite (Prindle, 1906, 1908). Placer scheelite is common (Joesting, 1942 [ATDM Pamph. 1]). The creek was mined from 1905 to 1940 and mining has been active in recent years as well (Cobb, 1976 [OFR 76-662]). Don Stein and Goldstream Valley Exploration worked a paystreak on Gilmore Creek in 1993 and 1994 (Bundtzen and others, 1994; Swainbank and others, 1995). The gold varies from 808 to 936 fine (Glover, 1950).

Comment (Workings): Workings / Exploration = The creek was mined from 1905 to 1940 and in recent years as well (Cobb, 1976 [OFR 76-662]). In 1922, a crew of twelve operated a Bagley scraper plant, an old surface cut was completed, and a new, 300 foot by 400 foot, surface cut was opened (Wimmler, 1922, p. 17). Two hydraulic plants were in operation in 1925 (Wimmler, 1925 [ATDM MR 195-8, p. 52]). In 1926, Tom Gilmore mined on a small scale by hand and by ground sluicing (Wimmler, 1926 [ATDM MR 195-11, p. 58]). In 1929, Steve Liedy mined by open cut and by drifting in the winter on upper Gilmore Creek (Wimmler, 1929, p. 166). Don Stein and Goldstream Valley Exploration worked a paystreak on Gilmore Creek in 1993 and 1994 (Bundtzen and others, 1994; Swainbank and others, 1995).

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Cobb, 1976 (OFR 76-662)

Comment (Geology): Age = Quaternary placer.
