Sinuk River

The Sinuk River 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 (Geology): Age = Holocene.

Comment (Reference): Primary Reference = Collier and others, 1908

Comment (Workings): 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.

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

Comment (Exploration): Status = Probably inactive

Comment (Geology): 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).
