Comments on the reserve resource information

  • RECORDS 2, 3, & 4 ARE BASED ON DEPOSITS >50 FEET BUT <100 FE WIDE AND ARE CALCULATED TO A DEPTH OF 100 FEET. RECORDS 5, 6, & 7 ARE BASED ON DEPOSITS >100 FEET WIDE AND A CALCULATED TO A DEPTH OF 200 FEET. ALTHOUGH OTHER MANGANESE DEPOSITS MAY EXTEND DEEPER, CALCULATIONS WERE NOT MADE ASSUMING THE EXPENSE OF MINING THIS DEEP ORE BY SURFACE METHODS WOULD BE TOO COSTLY. MILLER, 1947 ESTIMATES IRON IN THESE DISTRICTS TO BE NEARLY TWICE THAT OF MANGANESE.
  • RESOURCES AND GRADES BASED ON MILLER(1947) AND ADJUSTED TO AGREE WITH TOTAL DISTRICT VALUE REPORTED BY N.M.A.B. (REF. 066-067) GRADES ARE AVERAGED GRADES OF P-50 RESERVES; P-75 AVERAGE RESERVE GRADE IS 8.7%; P-90 RESERVE GRADE IS 7.1%.
