Identification information

Deposit ID 10001906
MRDS ID A012735
Record type Site
Current site name Kougarok River (lower)

Geographic coordinates

Geographic coordinates: -164.71532, 65.50432 (WGS84)
Relative position Sainsbury and others (1969) show that 3,000 feet of the main Kougarok River drainage has been placer mined upstream from a point 500 feet north of the Bendeleben C-6 and B-6 quadrangle boundary. The center of this mined section of the river is 1.2 miles west of the Nome-Taylor road. This locality was not included by Cobb (1972; MF 417; 1975; OFR 75-429).

Comments on the geologic information

  • 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.

Mining district

District name Kougarok

Comments on the workings information

  • 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).
