Grade Tonnage Curves and Tables

This tool calculates grade-tonnage curves and tables - that is, tonnage, metal quantity, mean grade, volume and conventional benefit, above or between chosen grade cutoffs. These may be calculated from:

• a grade variable, such as an estimate on a grid. A macro variable may also be used as input (e.g. this could store conditional simulations), in which case the curves are calculated for each realization of the macro variable before being averaged;
• tonnage and metal quantity variables, as may be calculated by Uniform Conditioning;
• an anamorphosis model, which can be created in Exploratory Data Analysis by saving a geostatistical set with a Gaussian variogram.

The region over which the calculations are done may optionally be restricted according to surfaces, closed meshes, or polygons.
