This paper discusses a Personal Computer (PC) software package that reduces the time required to evaluate a mineral reserve. It provides for: •Entry of borehole data onto PC diskettes and the creation of a borehole database; •Capture of map data using an attached X-Y digitizer; •Calculation of uniform square grids for thickness, mineral qualities, overburden ratio, etc., •Compilation of multiple such grids into a digital model, and iterative evaluation of the model with the user applying constraints and cut-off values; and • Graphic display of grid cells (blocks) showing which cells failed, and on which constraint(s), and a complete reserve report showing tonnages, averages, histograms, and quality arrays.
