Comments on the production information

  • PERCENT RECOVERY FOR P2O5 IN RECORD A IS ACTUALLY 69.4.
  • DIFFERENCE IN OUTPUT FIGURE FROM CALCULATED NUMBER IS DUE TO NUMERICAL ROUNDING. PHOSPHATE ROCK PRODUCT IN RECORD A IS THE COMBINED PEBBLE AND FLOTATION-CONCENTRATE PRODUCTS.

Comments on the reserve resource information

  • MATRIX QUANTITY IS AN ESTIMATE--CURRENT PUBLISHED RESERVES FOR THE CLEAR SPRINGS MINE ARE NOT AVAILABLE. ACTUAL MATRIX QUANTITY FIGURE IS 115,310,800 METRIC TONS OF ORE. PEBBLE = 12% OF ORE. MINE RECOVERY = 85%. CURRENT ASSAY GRADES FOR F, U3O8, FE2O3, AL203, AND MGO IN MATRICES 1 AND 9 ARE NOT AVAILABLE; ASSAY GRADES SHOWN ARE THOSE THAT WERE DETERMINED FOR THE SEPTEMBER 1979 EVALUATION OF THIS PROPERTY. M9C4=M1C1 MATRIX 9, COLUMN 4 EQUALS MATRIX 1, COLUMN 1. Q-MATRIX 2 COL 1 REPRESENTS RESERVES ESTIMATED FOR THE 1993 ADIT UPDATE.
  • ADIT UPDATE 1994: THIS PROPERTY REOPENED IN 1994.
