Economic information

Comments on the geologic information

  • Geologic Description = Hoare and Cobb (1977, p. 35) reported that core samples of unconsolidated deposits in Goodnews Bay, apparently collected by a private company, contained detectable amounts of platinum. The platinum is said to have been concentrated in clay layers. Most samples also contained cinnabar and native mercury. One tiny diamond is also said to have been found. The highest concentrations were in the north part of the bay, south of Beluga Hill.
  • Age = Holocene.

Mining district

District name Goodnews Bay

Comments on the workings information

  • Workings / Exploration = A core sampling program was apparently completed in Goodnews Bay in 1969. A followup sampling and aeromagnetic survey was apparently completed in 1970 with unknown results (Hoare and Cobb, 1977, p. 35).
