Comments
Comment (Geology): Geologic Description = Float prospecting led to the discovery of a 6- to 8-foot thick siliceous bed containing disseminated scheelite. A sample of this material assayed 3.45 percent tungsten oxide over 27 inches (Jasper, 1955). Kodiak Exploration Company sent a sample of mineralized rock from this prospect or from their Chalet Mountain property (KD025) to Wah Chang Corporation for assay and examination. They identified the so-called siliceous material as tactite or skarn (Jasper, 1955).
Comment (Workings): Workings / Exploration = Sample collected across 27 inches contained 3.45 percent tungsten oxide.
Comment (Deposit): Model Name = W skarn? (Cox and Singer, 1986; model 14a)
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Rose and Richter, 1967
Comment (Geology): Age = Cretaceous or younger
