Deposit ID 10307264
Record type Site
Current site name Unnamed (Kougarok River)

Geographic coordinates

Geographic coordinates: -164.8034, 65.66932 (WGS84)
Relative position This location is approximately located, probably within one mile. Smith (1908) reports it to be a lode occurrence near the mouth of Taylor Creek. Taylor Creek is a major east tributary to Kougarok River. The mouth of Taylor Creek is 1,000 feet north of the termination of the Nome-Taylor road at Taylor. This is locality 1 of Cobb (1972; MF 417; 1975; OFR 75-429).

Comments on the geologic information

  • Geologic Description = Smith (1908, p, 244) reports that copper sulfides (chalcopyrite ?)are present in metamorphosed limestone (marble) on Kougarok River somewhere near the mouth of Taylor Creek. Bedrock in the upper Kougarok River area is part of a lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1969; Till and others, 1986).
  • Age = Unknown; if epigenetic then perhaps Cretaceous. The major episode of epigenetic mineralization on Seward Peninsula accompanied higher temperature metamophism and mid- to Late Cretaceous granitic plutonism in the region.
