Comments on the geologic information

  • SHAPE OF ORE BODY: OREBODY APPEARS TO BE A NEARLY HORIZONTAL TABULAR MASS EHICH IS BOUNDED LATERALLY BY FAULTS AND WHICH IS BROKEN INTO A COMPLEX SERIES OF BLOCKS WHICH RISE LIKE STEPS IN A NORTHWARD DIRECTION. TYPE OF WALLROCK ALTERATION: SERPENTINIZATION. STRIKE AND DIP OF MINERALIZED ZONE: MINERALIZED TREND IS ABOUT N12E. THE ZONE IS BASICALLY HORIZONTAL.
  • CHROMIUM PICOTITE INDIVIDUAL GRAIN SIZE AVERAGES 0.2-0.5MM IN DIAMETER. CHROME TO IRON RATION IS 1.55 TO 1. CHROMITE OCCURRENCE IS BOTH MASSIVE AND DISSEMINATED WITHIN THE OREBODY.
