Geologic information

Identification information

Deposit ID 10307909
Record type Site
Current site name Sinuk River

Geographic coordinates

Geographic coordinates: -165.856, 64.74978 (WGS84)
Relative position Sinuk River is the major drainage along the southwest flank of the Kigluaik Mountains. Collier and others (1908, plate X) show the river to be gold-bearing for several miles downstream from Rulby Creek, a small east tributary (NM016). This location is the approximate midpoint of the auriferous section that extends south into the Nome C-2 quadrangle.

Comments on the geologic information

  • Geologic Description = The Sinuk River is the major drainage along the southwest flank of the Kigluaik Mountains. Collier and others (1908, plate X) show the river to be gold-bearing for several miles downstream from Rulby Creek, a small east tributary (NM016). The placer deposits on Sinuk River itself are probably of river-bar type and transient in nature. The headward limit of the auriferous portion of the river is about where a belt of iron and lead-zinc deposits (NM014, NM014, NM017, NM018, NM019, and NM020) cross the river. Bedrock is not commonly exposed along Sinuk River, and over much of its length it reworks glacial deposits derived from the Kigluaik Mountains (Sainsbury, Hummel, and Hudson, 1972; Kaufman and others, 1989).
  • Age = Holocene.

Economic information about the deposit and operations

Development status Prospect

Comments on exploration

  • Status = Probably inactive

Mining district

District name Nome

Comments on the workings information

  • Workings / Exploration = Sinuk River was probably worked on a small scale prior to WWI. Production figures are not available, but some gold was probably produced by pan, rocker, or other small-scale operations.
