Comments on the production information

  • LEAD CONCENTRATE CONTAINS 73 PERCENT LEAD AND 650 GRAMS PER METRIC TONS OF SILVER. ZINC CONCENTRATE CONTAINS 52 PERCENT ZINC.

Comments on the reserve resource information

  • RESOURCE IS BASED ON 15 YEARS OF STATED PROVEN RESERVES. GRADES WERE CALCULATED FROM HEAD GRADES AND 30 PERCENT ESTIMATED DILUTION. TONNAGE ESTIMATES WERE BASED ON 15 YEARS OF PRODUCTION AND ADJUSTED FOR 30 PERCENT DILUTION. ORE GRADES ARE EXPECTED TO DECLINE OVER TIME.
