Comments on the production information

  • CLARA FLOUSPAR OREBODY PRODUCES 57% OF TOTAL YEARLY OUTPUT, BARITE OREBODY THE REMAINING 43%. CHEMICAL AND DRILLING MUD GRADE BARITE ARE THE PRODUCTS OF BOTH BARITE OREBODY, AND RETREATING OF FLOUSPAR TAILINGS FOR BASO4. DAMES & MOORE REPORT A YEARLY OUTPUT OF 30,000MT OF ORDINARY GRADE BARITE. DAILY OUTPUT WAS CALCULATED AS: 30,000MT/250 YEARLY WORKING DAYS = 120MT/DAY

Comments on the reserve resource information

  • M1C1=M9C4 M2C1=M9C5. M1 = FLOUSPAR OREBODY M2 = BARITE OREBODY
  • SUBSIDIARY OF METALLGESELLSCHAFT AG ACID GRADE FLUORSPAR, 3 GRADES BASO4.

Comments on other economic factors

  • MINE + MILL COSTS BETWEEN THE FLOUSPAR AND BARITE OREBODIES, WERE NOT DIFFERENTIATED IN DAMES & MOORE REPORT. DIFFERENTIATION WAS MADE FROM THE RELATIVE PERCENT ORE OUTPUT FOR EACH OREBODY, TO THE TOTAL OUTPUT OF THE CLARA MINE.
