Comments on the geologic information

  • Geologic Description = About 8,000 feet of placer workings have been mapped along this drainage between elevations of about 45 and 130 feet. The workings start about 5,000 feet upstream from the mouth of the creek on Taylor Lagoon. Although prospected in the 1900's (Collier and others, 1908), principal mining was by dredging in the 1930's (Cobb, 1978). Some gravels were locally-derived schist and greenstone that was coarse and not well-rounded (Smith, 1910). The gravels were about 11 feet thick on bedrock and permafrost was locally encountered (Smith, 1933). Some beach gravel was encountered and mined but the location was not reported. The paystreak was reported to have been mined out (Smith, 1939). The elevation and location of this placer indicates that it was influenced by Quaternary sea level fluctuations. Bedrock in the area is part of a pelitic schist assemblage of possible Cambrian or Precambrian age (Till and others, 1986).
  • Age = Quaternary.

Comments on the production information

  • Production Notes = The dredge operating on this creek was apparently the major producer in the area between 1932 and 1935; considering the extent of the workings the deposits may have been high grade. The paystreak was reported to have been mined out (Smith, 1939).

Comments on the workings information

  • Workings / Exploration = About 8,000 feet of placer workings have mapped along this drainage between elevations of about 45 and 130 feet. The workings start about 5,000 feet upstream from the mouth of the creek on Taylor Lagoon. Although prospected in the 1900's (Collier and others, 1908), principal mining was by dredging in the 1930's (Cobb, 1978).
