Comments on the production information

  • ORE PRODUCED BY THE KAEFERSTEIGE MINE SUPPLIES 66% OF ORE TREATED AT KARLSUHE MILL. MAJORITY OF REMAINING ORE TREATED AT MILL IS PURCHASED. PURCHASED ORE GRADE TYPICALLY RUNS 50.00% CAF2 TO AS HIGH AS 70.00% CAF2, WITH AN AVER. OF 55.80%, AS REPORTED BY DAMES & MOORE PRODUCT DESIGNED CAPACITY AS CALCULATED BY: ((DESIGNED MINE PRODUCTION/ANNUAL WORKING DAYS)/PERCENT ORE TREATED AT MILL AS PRODUCED BY KAEFERSTEIGE MINE.) CAPACITY OF THE PLANT AT THE KARLSRUHE PORT IS AROUND 50,000 DRY TPA.

Comments on other economic factors

  • THE COMPANY EXPLOITS THE DEPOSIT OVER A LENGTH OF 1KM BY SUBLEVEL CAVING. DRILLING IS CARRIED OUT BY ELECTRO-HYDRAULIC JUMBES, AND THE ORE LOADED BY LHDS. CRUSHING IS CARRIED OUT UNDERGROUND, AND A MODERN RAMP SYSTEM ENABLES TRUCKS TO TRANSPORT CURSHED ORE TO THE SURFACE.
  • MINING IS BY SUBLEVEL CAVING TECH. MINE SUPPORT IS BY CEMENTED BACKFILL
