Comments on the geologic information

  • ACCESSORY MINERALS INCLUDE HEAZLEWOODITE AND AWARUITE.
  • PERVASIVE ALTERATION HAS FORMED THREE ZONES WITHIN THE OREBODY. THE LEAST ALTERED IS A CORE OF DUNITE. THIS IS SURROUNDED BY A ZONE THAT IS TOTALLY SERPENTINIZED. FINALLY THERE IS A MARGINAL ZONE OF TALC-CARBONATE ALTERATION.
