Comments on the reserve resource information

  • GRADE-APPROX 300,000,000 SQ. FT. MINERALIZED ROCK. ASSUME 2.67 SG THEN TONNAGE FACTOR IS 2000LBS/(62.4LBS /CU.FT.X2.67)=12.000CU.FT.PER TON. TONS ORE PER VERTICLE FT. =SQ.FT ORE/TONNAGE FACTOR=25,000,000TONS/FT. HORIZON IS APPROX 40FT.THICK,TOTAL TONS=25,000,000X40=1 BILLION. GROSS APPROXIMATION AND ERRORS ARE MUCH GREATER THAN THAT TONNAGE DIFFERENCE OBTAINED BY CONVERTING TO METRIC TONS. THE VALUE 1 BILLION METRIC TONS IS ADDED AT THE 50% PROBABILITY LEVEL. ERROR IS PROBABLY + OR - 30%.
