Comments on the geologic information

  • Geologic Description = Baggage prospect was staked in the 1970's by Cities Services Mineral Corporation, and was considered a possible porphyry-Cu prospect (David Hedderly-Smith, oral communication, 1998). The regional geology of the area is mapped as Paleozoic-Precambrian biotite gneiss and amphibolite- grade schist (Foster, 1970). The prospect lies within the eastern Yukon-Tanana Y1 subterrane (Foster and Keith, 1994).
  • Age = Likely to be one of three ages of porphyry mineralization -- 90 to 100 Ma, 70 Ma, or 55 Ma -- based on dates from other porphyry prospects in the Yukon-Tanana terrane.
