Theoretical aspects of grade-tonnage calculations
Conclusions A theoretical approach to grade-tonnage calculations shows that methods based on accumulations are incorrect. Strictly correct calculations must involve multiplication of the various spatial functions, rather than the multiplication of measurements made at locations. If, however, polygonal interpolation is employed to estimate the spatial functions involved, then the results of the two approaches are identical. If any other interpolation procedure is used, then differences become obvious. Where trends are present in the data being computed, accumulation methods are likely to introduce serious errors.
