Comments on the geologic information

  • Geologic Description = The lower mile of Ridgeway Creek carries gold, including small nuggets (Smith, 1910), but mining has not been reported (Cobb, 1978, 78-191). The regional contact between pelitic schist of possible Cambrian or Precambrian age and a lower Paleozoic metasedimentary assemblage passes through the headwaters of Ridgeway Creek (Till and others, 1986).
  • Age = Quaternary; the numerous incised terraces along the Casadepaga River and its major tributaries (including Lower Willow Creek) indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Council

Comments on the workings information

  • Workings / Exploration = Prospecting was done on Ridgeway Creek prior to WW I but the unavailability of water was a handicap to early mining and none has been reported.
