Comments on the geologic information

  • THE CHROME BEARING SAND HAD ITS ORIGIN IN AN AREA OF SER- PENTINE. SUBSEQUENT WEATHERING AND EROSION FREED FINELY DIVIDED CHROMITE PARTICLES. THE CHROMITE ACCUM- ULATED AS A MINABLE SAND AND GRAVEL PLACER ALONG A SMALL TRIBUTARY OF DEER CREEK. CHROMITE GRAINS AVERAGE 1/25 INCH IN DIAMETER

Comments on the reserve resource information

  • Q MATRIX REFLECTS TONNAGE & GRADE DERIVED FROM THE WASHED SAMPLE REPORTED IN R MATRIX. R MATRIX: .036 CR2O3 X 11,400 TONNES SAND = 410 TONNES CR2O3 Q MATRIX: CHROMITE ORE CONSISTS OF 11,400 TONNES SAND AND 6,700 TONNES GRAVEL WHICH CONTAIN 410 TONNES CR2O3. TOTAL CHROMITE ORE = 11,400 + 6,700 = 18,000 TONNES (ROUNDED TO THE NEAREST 1,000 TONNES). OVERALL GRADE = 410 TONNES CR2O3 / 18,000 TONNES ORE = 2.3% CR2O3 M9C4 = M1C1.
