| “Proven (Measured) Reserves” are reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes, and the grade is computed from the results of detailed sampling, and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is so well defined that the size, shape, depth and mineral content of the reserves are well established. |
