Location and accuracy This occurrence is apparently in bottom sediments of Goodnews Bay. The map site on a mud flat at shallow depth in Goodnews Bay, about 1.5 miles south of Beluga Hill. It is included in Hoare and Cobb (1977) under the name 'Goodnews Bay'.

Geologic setting

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.

Production and reserves

Workings or 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).
