Comments on development

  • SINCE 1970 OPEN CAST MINING IN THE WESTERN PART OF THE DEPOSIT. DESIGNED SURFACE MINING IN THE WESTERN PLUS EASTERN PART OF THE DEPOSIT, SIZE 500 M X 300 M DOWN TO 100 M. UNDERGROUND MINING WILL FOLLOW. IN 1975, THE CUTOFF GRADE WAS UPPED FROM 0.35% NI TO 0.4% NI. FOR UNDERGROUN MINING THE CUTOFF GRADE IS EXPECTED TO BE 0.7% NI.
