Comments on the reserve resource information

  • M1C1=N/CUM (MATRIX 1 COLUMN 1 IS NONCUMULATIVE). MATRIX 1 CONSIDERS ONLY ORE FOUND IN ORE ZONE NO. 1.
  • LOW GRADE, LOW TONNAGE, HIGH COST OPERATION; BARRING ANY NEW FINDINGS OR RADICAL CHANGE IN WORLD TIN INDUSTRY, THIS DEPOSIT HAS A SMALL CHANCE OF BEING DEVELOPED.
