Comments on the geologic information

  • ORE IS TO BE TAKEN FROM 8 DIFFERENT DUMPS AND FROM THE EXISTING HIGHWALL OF THE OLD ETTA MINE. CONSEQUENTLY, OREBODY DIMENSIONS CANNOT BE GIVEN. ALL ORE IN THE DUMPS IS FROM PREVIOUS MINING OF PEGMATITES.

Comments on the production information

  • RECOVERIES HAVE BEEN ROUNDED. RECOVERIES ARE ACTUALLY 71.8% FOR TIN, 94.5% FOR TANTALUM, AND 77.9% FOR NIOBIUM. NIOBIUM.
  • PRODUCT A IS THE TANTALUM-COLUMBIUM CONCENTRATE; PRODUCT B IS A TIN CONCENTRATE; AND, PRODUCT C IS GRAVEL WHICH IS THE TAILS FROM MILLING. PRODUCT C, GRAVEL, COMES FROM THE COARSE TAILS (SEE APPENDIX B-4 OF BACK-UP DATA).

Comments on the reserve resource information

  • THERE ARE 8 ADDITIONAL DUMPS THAT HAVE NOT BEEN EVALUATED BY THE PACER CORP. RESERVES OF TANTALUM, COLUMBIUM, AND TIN ARE LIKELY TO INCREASE AFTER EVALUATION OF THESE ADDITIONAL DUMPS. SEE APPENDIX B-2 OF REPORT. THE ABOVE RESERVE DATA WAS PROVIDED BY PACER CORP. (SEE APPENDIX B-2). ALTHOUGH THE FIGURE IS BASED ON MINIMAL EXPLORATION, AND CONSEQUENTLY IN A LOWER PROBABILITY CATEGORY, THE EVALUATOR BELIEVES MOST OF THE RESERVE WILL BE CONFIRMED.
  • RESOURCES IN RECOVERABLE MT PROPOSED MINING WILL REWORK EXISTING DUMPS AND OPEN PIT MINE
