Comments on the reserve resource information

  • THE QUANTITY RESOURCES ARE ROUNDED DOWN FROM THE SUMMARY FILE FIGURE. Q MATRIX REFLECTS TONNAGE & GRADE DERIVED FROM THE WASHED SAMPLE REPORTED IN R MATRIX. R MATRIX: .029 CR2O3 X 43,700 TONNES SAND=1,267 TONNES CR2O3 Q MATRIX: CHROMITE ORE CONSISTS OF 43,700 TONNES SAND AND 4,400 TONNES GRAVEL WHICH CONTAIN 1,267 TONNES CR2O3. TOTAL CHROMITE ORE = 43,700 + 4,400 = 48,000 TONNES (ROUNDED TO THE NEAREST 1,000 TONNES). OVERALL GRADE = 1,267 TONNES CR2O3 / 48,000 TONNES ORE = 2.6% CR2O3 M9C4 = M1C1.
