Identification information

Deposit ID 10307710
Record type Site
Current site name Ninilchik

Geographic coordinates

Geographic coordinates: -151.5626, 60.11948 (WGS84)
Relative position Cobb (1972, MF-377) located this occurrence on the shores of Cook Inlet about six miles northeast of the town of Ninilchik. However, small amounts of gold are probably present in small amounts along the entire beach at this vicinity. This is Cobb's (1972, MF-377) location 5 and is accurate to within a half a mile.

Economic information

Comments on the geologic information

  • Geologic Description = Gold has been found along the shoreline in a thin gravel layer about 2 feet below the surface. The area was mined intermittently from 1889 to 1911, mostly by rocker and small sluice boxes. The gold is probably derived from the Kenai Formation; the lode source was far to the east (Martin and others, 1915).
  • Age = Recent.

Comments on the workings information
