General comments

Subject category Comment text
Deposit LITTLE GEOLOGIC MAPPING AND THIN - AND POLISHED - SECTION WORK HAS YET BEEN UNDERTAKEN SO ROCKS AND RELATIONS ARE LITTLE UNDERSTOOD. DENSE TROPICAL VEGETATION AND DEEP WEATHERING AND LEACHING INHIBIT SURFACE OBSERVATIONS.
Deposit DIMENSIONS REFER TO ANOMALOUS AREA ONLY. FUTURE DRILLING MAY REVISE AREA OF SUPPOSED MINERALIZATION.
