Comments on the geologic information

  • Geologic Description = Berg and Cobb (1967, p. 7) report that in 1920 samples were collected from chalcopyrite lenses which could be traced for 1 mile. Two samples assayed up to 0.31 ounce per ton gold, 8.1 ounces per ton silver, and 24.4 percent copper. Bedrock in this area consists of Upper Jurassic to Lower Cretaceous sedimentary units of the Naknek formation. The deposit type is unknown but may be a polymetallic vein controlled by a contact zone of an unmapped dike or sill.
