Sledge Creek

The Sledge 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.

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 (Reserve-Resource): Reserves = Sledge Creek could contain a largely unmined placer deposit (C.C. Hawley, personal observation, 1994, 2000).

Comment (Workings): Workings / Exploration = Drift mining reported in 1916; small open-cut surface mining on and below U.S. Mineral Survey No. 1343 probably took place in about 1925 (Heiner and Porter, 1972).

Comment (Exploration): Status = Probably inactive

Comment (Geology): Geologic Description = Sledge Creek has been mined at the surface in a shallow deposit near where the creek emerges from the hills and enters the Snake River valley. Drift mining at two unknown locations was also reported by Mertie (1918 [B 662-I, p. 454]). Patented claim U.S. Mineral Survey No.1343 is in lower Sledge Creek, immediately above the surface placer cut, and claim U.S. Mineral Survey No. 1840 is in the south fork of Sledge Creek. Gold and tungsten were reported at the former site (Heiner and Porter, 1972, Kardex site Kx 52-259). Tungsten in scheelite was also reported by Thorne and others (1948, p. 33) in Sledge Creek. Kennecott Exploration Company found gold in two pan concentrate samples collected 1,500 and 3,000 feet below the south fork junction. The samples, contained more than 4 and more than 2 ppm gold respectively. They also contained anomalous amounts of tin, suggesting that cassiterite is present. This placer deposit is at an elevation of 150 to 175 fee, suggesting that it may have been influenced by Quaternary sea-level changes during its development. Bedrock of the Sledge Creek drainage is mostly chloritic and calcareous schist. One or more branches of the Rodine fault parallel upper Sledge Creek (Bundtzen and others, 1994). At least some of the placer gold in Sledge Creek was probably derived from erosion of the Alpha Ridge deposit (NM171).

Comment (Reference): Primary Reference = This report

Comment (Geology): Age = Quaternary.

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