Geographic coordinates

Geographic coordinates: -164.30027, 64.67831 (WGS84)
Relative position The part of Solomon River included here has been continuously placer mined from an elevation of about 100 feet upstream to an elevation of about 175 feet. It extends for 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. This part of the Solomon River was included in localities 99 and 101 of Cobb (1972, MF 445; 1978, OF 78-181).

Comments on the geologic information

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

District name Nome

Comments on the production information

  • 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.

Comments on the workings information

  • 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.
