Comments on the geologic information

  • THE GENERAL STRUCTURE IN THE AREA IS A BROAD S-W PLUNGING ANTICLINE. THE MAPULA/MASARA MINE AREA IS CROSSCUT BY TWO MAFOR NW-SE TRENDING FAULTS. THE ORE TYPICALLY OCCURS AT THE ANDESITE-DIORITE CONTACT, BUT IS MORE PROMINANT ON THE FOOTWALL SIDE OF THE ANDESITE.
