Comments on the production information

  • AS OF 1990, ALL BULK CONCENTRATE IS SHIPPED TO COPSA MICA FOR SMELTING AND REFINING.
  • FOR YEARS 1984-1986, THE MINE PRODUCED APPROXIMATELY 750,000 METRIC TONS OF ORE THROUGHPUT. FOR YEARS 1987-1990, THE ORE THROUGHPUT WAS ESTIMATED TO BE APPROXIMATELY 1,000,000 METRIC TONS. THE AVERAGE HEAD GRADE FOR THE ORE WAS .20%-.30% LEAD AND .40%-.60% ZINC. BULK LEAD/ZINC CONCENTRATE PRODUCTION FOR YEARS 1984-1986 WAS ESTIMATED TO BE 7,000 METRIC TONS WHILE YEARS 1987-1990 PRODUCED AN ESTIMATED 10,000 METRIC TONS. PYRITE CONCENTRATE WAS ESTIMATED TO BE 75,000 METRIC TONS PER YEAR FOR YEARS 1984-1986 AND 100,000 METRIC TONS PER YEAR FOR YEARS 1987-1990. THE AVERAGE GRADE FOR THE BULK CONCENTRATE IN 1990 AVERAGED 12%-14% LEAD, 30%-33% ZINC, AND 1%-1.5% COPPER. AS OF 1990, THE CORANDA CERTEJ MINE WAS RESPONSIBLE FOR APPROXIMATELY .58% LEAD AND .99% ZINC PRODUCTION FOR ALL EASTERN EUROPEAN MINING PRODUCTIONS. ALL PRODUCTION COMPLETED AT THE CORANDA CERTEJ MINE AS OF 1990 WAS 80% FROM OPEN PIT MINING AND 20% FROM COMBINED UNDERGROUND METHODS.

Comments on the reserve resource information

  • THE CORANDA CERTEJ MINE HAS MINABLE RESERVES OF APPROXIMATELY 20 MILLION METRIC TONS. NO INFORMATION IS AVAILABLE CONCERNING THE METAL CONTENT OR THE STATUS OF THESE RESERVES. THESE RESERVES ARE BELIEVED TO BE ENOUGH TO LAST APPROXIMATELY AN ADDITIONAL 20 YEARS.
