Cleary Creek

The Cleary 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 = From 1903 through 1924 production was about 1,129,650 fine ounces (Cobb, 1976; OFR 76-633). Production amounts have not been reported for recent mining activites.

Comment (Reference): Primary Reference = Prindle, 1905

Comment (Geology): Geologic Description = Cleary Creek is a highly productive placer gold creek that has been mined over its entire length of over 5 miles. Gold production began as early as 1903 and production continues today from fresh placer cuts near the mouth of Chatham Creek. In the early 1900's, reports about Cleary Creek describe the depth to bedrock schist as being from 14 to more than 135 feet (Prindle and Katz, 1913, p. 107). Gravel is a variety of schist, some hornblende-garnet rock and boulders of vein quartz. These early reports also describe the gold occurring in the basal 1 to 7 feet of gravel and the top 1.5 to 4 feet of bedrock, with a paystreak of 35 to 150 feet wide; the average value of the paystreak was 0.566 ounces of gold per cubic yard (Prindle, 1905). Concentrates contained gold, stibnite, cassiterite, scheelite, pyrite, garnet, and rutile (Prindle, 1905). From 1903 through 1924 production was about 1,129,650 fine ounces (Cobb, 1976; OFR 76-633). The largest nugget reported weighed 13.51 ounces. Most production was from drift mines working a pay streak 150 feet wide with an average thickness of 5 feet. In 1915, most mining in the Chatanika flats was on benches on the south side of the Chatanika valley (Eakin, 1915). U.S.S.R. & M. Dredge no. 3 worked on lower Cleary Creek and near Chatanika from 1928 to 1942 and from 1946 to 1963. Dredge no. 5 worked on upper Cleary Creek from 1929 to 1942 (R.M. Chapman, 1978, U.S.G.S. memorandum). In 1996 and 1997, Alf Hopen leased placer ground from the Alaska Gold Co. on Upper Cleary Creek (Swainbank and others, 1997). In 1999, fresh placer cuts on Cleary Creek were observed at the mouth of Chatham Creek (J. Schaefer, field observation, 1999).
