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)
