Solomon River

The Solomon 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 (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a).

Comment (Reference): Primary Reference = Cobb, 1978 (OF 78-181)

Comment (Production): Production Notes = Placer gold was discovered in 1899 and mining started in 1900 when about $10,000 (or 485 fine ounces) were produced (Brooks and others, 1901). Lu and others (1968) compiled reported production and determined that more than about $2,500,000 dollars, or 125,000 ounces at $20 per ounce, had been produced from the general Solomon River area. This is a minimum estimate of production.

Comment (Geology): Geologic Description = The active drainage of the Solomon River has been continuously placer mined mined, mostly by dredging, from an elevation of about 100 feet upstream to an elevation of about 175 feet. This is a distance of about 5 miles starting 0.7 miles downstream from Quigleys Camp and continuing upstream to the mouth of Winston Creek, 1 mile above East Fork. Also see SO015 (lower Solomon River ). Bedrock here is part of a lower Paleozoic metasedimentary assemblage (Sainsbury and others, 1972, OFR 511; Till and others, 1986).

Comment (Geology): Age = Quaternary; the location and elevation (100 to 170 feet) of this area indicate that it was affected by Quaternary sea level fluctuations.

Comment (Exploration): Status = Active?

Comment (Workings): Workings / Exploration = About 5 miles of dredge and open-cut placer workings are present along this part of the Solomon River, primarily along the active drainage.
