Summary

  • More subdivision of rock types – New interpretations
  • Better location and description of major structures
  • Better linkage between mineralization, geology and structure – including
          • Recognition of VMS alteration
          • 3 styles Au mineralization
          • Proterozoic Au (remobilization)
