Stewart River (above Mountain Creek)

The Stewart River (above Mountain Creek) 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.

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 (Reference): Primary Reference = Smith, 1909

Comment (Workings): Workings / Exploration = Placer gold mining above Mountain Creek on Stewart River was reported in the early years of the Nome district. Smith (1909, p. 280) noted mining, almost certainly small scale, at 'two or three camps' along Stewart River above Mountain Creek.

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

Comment (Geology): Geologic Description = Placer gold mining above Mountain Creek on Stewart River was reported in the early years of the Nome district. Smith (1909, p. 280) noted mining, almost certainly small scale, at 'two or three camps' along Stewart River above Mountain Creek.? Stewart River and its tributary Mountain Creek have floodplains of Holocene alluvium as much as about 0.2 mile wide that are developed on modified drift of the Nome River glaciation. The downstream limit of the slightly modified drift of the Stewart River glaciation is about 1 mile above the confluence of Mountain Creek and Stewart River (Bundtzen and others, 1994). Some placer gold could, therefore, have been derived by reworking slightly auriferous glacial drift derived ultimately from the Kigluaik Mountains and closer gold lodes, as in the Divide Creek area (NM057, NM058, NM111, NM118). Some gold was probably derived from Fred Creek, the next upstream southern tributary,which is known to be auriferous (NM064). Also, the divide between upper Mountain and upper Goldbottom Creeks has little relief, and gold in this area could have been derived from the major fault system that hosts the California lode in upper Goldbottom Creek (NM062). As mapped by Hummel (1962 [MF 242]) and one of the compilers (C.C. Hawley), this fault projects north into lower Fred Creek and the Stewart River valley; it could contain other lode gold deposits like the California lode.

Comment (Geology): Age = In large part Holocene, with gold derived from reworking of Pleistocene drift or fed by Fred and Mountain Creeks.

Comment (Exploration): Status = Inactive
