Comments on the geologic information

  • Geologic Description = The only information available on this prospect is that 34 lode claims were staked in 1973 (DeYoung, 1978). Its location just south of the Chandalar District gold lodes makes it of some interest.
  • Age = Middle Cretaceous based on arguments by Dillon (1982) that the age of emplacement of the gold-bearing quartz veins of the Koyukuk and Chandalar districts was between the Neocomian metamorphism of the Devonian host rocks and their erosional unroofing and cooling in Albian time.
