Kougarok River (lower)

The Kougarok River (lower) 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 (Workings): Workings / Exploration = Placer mine tailings from surface operations (probably dredge or dragline) are present along at least 3,000 feet of the main Kougarok River drainage (Sainsbury and others, 1969). Sainsbury and others (1969) note that placer mining for gold occurred at many places along the Kougarok River from this location north to near Taylor (see Kougarok River, BN035).

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Sainsbury and others, 1969

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

Comment (Geology): Geologic Description = At least 3,000 feet of the Kougarok River has been placer mined for gold here. This mining was probably by dredge and/or dragline. Information about the nature of the paystreak or production is not available. Bedrock in nearby uplands is part of an Ordovician mafic metavolcanic assemblage (Sainsbury and others. 1969; Till and others, 1986) but the gold in this part of the stream may not be locally derived. The Kougarok River drainage has been locally placer mined over most of its length upstream from this locality (Sainsbury and others, 1969; Cobb, 1972, MF 417; 1975, OFR 75-429). Placer mining in this drainage has also recovered significant gold from bench gravels; the placers in this part of the stream are probably the result of at least two major cycles of erosion and alluvial placer development.

Comment (Geology): Age = Quaternary
