Tamarack Creek

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

Comment (Commodity): Ore Material = Silver (native)

Comment (Workings): Workings / Exploration = Mertie (1936) reports that a paystreak yielding good returns was being mined in 1934.

Comment (Production): Production Notes = Production from Tamarack Creek probably is combined with production for Spruce Creek (OP026).

Comment (Reference): Primary Reference = Mertie, 1936

Comment (Geology): Geologic Description = The rocks in the vicinity of Tamarack creek are shale and siltstone. The creek probably also drains Cretaceous or Tertiary monzonite plutons, and dikes of various compositions (Chapman and others, 1985). These intrusive rocks probably are the source of the placer gold in Tamarack Creek (Bundtzen and others, 1987).? Heavy minerals in pan concentrates from Tamarack Creek include magnetite, ilmenite, pyrite, pyroxene, amphibole, and several grains of native silver (Bundtzen and others, 1987). Mertie (1936) reports that a paystreak yielding good returns was being mined in 1934.? Production from Tamarack Creek probably is combined with production figures for Spruce Creek (OP026).

Comment (Geology): Age = Quaternary.
