Comments on the reserve resource information

  • THE STATED RESERVES OF 12,000,000 FOR THIS MINE ARE FOR 20 YEARS OF PRODUCTION AT A 75 PERCENT CONFIDENCE LEVEL.

Comments on other economic factors

  • AS OF THE TIME OF THIS REPORT, THIS UNDERGROUND MINE OPERATES WITH A DAILY CAPACITY OF PRODUCING 2,400 METRIC TONS OF ORE, PROVIDED THAT THE MINE OPERATES 250 DAYS PER YEAR AND WORKS 3 SHIFTS PER DAY. THIS DATA IS FOR THE YEAR 1989. THE OREBODY HAS BEEN DRILLED TO A DEPTH OF 1,300 METERS, AND MINERALIZATION IS BELIEVED TO EXTEND BEYOND THIS DEPTH. THE MINE EQUIPMENT IS OLD AND POORLY MAINTAINED.
  • LEAD CONCENTRATE ASSAYS 72 PERCENT AND ZINC CONCENTRATE ASSAYS 55 PERCENT. THE MILL HAS A CAPACITY OF ONE MILLION METRIC TONS PER YEAR, BUT HAS NEVER BEEN UTILIZED. AS OF THE TIME OF THIS REPORT, THE CAPACITY OF THE MILL WAS PRODUCING 20,000 METRIC TONS OF LEAD CONCENTRATE GRADING 72 PERCENT LEAD PER YEAR AND 20,000 METRIC TONS OF ZINC CONCENTRATE GRADING 55 PERCENT ZINC PER YEAR. THESE CAPACITY MEASURMENTS ARE ACCOMPANIED BY THE ASSUMPTION THAT THE MILL OPERATES 300 DAYS PER YEAR AND WORKS 3 SHIFTS PER DAY. THE MILL EQUIPMENT IS COMPOSED OF BRITISH AND RUSSIAN ORIGIN. THIS DATA IS CURRENT AS OF THE YEAR 1989. FEED GRADES ASSAY 2.5 PERCENT LEAD AND 2.5 PERCENT ZINC.
  • THE MINE AND MILL FACILITY HAS BEEN ADVERSLY AFFECTED BY CIVIL UNREST OWING TO POLITICAL PROBLEMS AND DELAYED SALARY PAYMENTS.
