Reserve Classification

Function

This command is a one step reserve classification analysis. The purpose of the analysis is to estimate quantities and qualities of the mine reserve, dividing it into various zones based on the distance to the closest drillhole. The reserve estimation is less reliable when the closest drillhole is farther away. Typically the following zones are defined:

Measured <1320ft
Indicated >1320ft, <3960ft
Inferred >3960ft, <15840ft
Hypothetical >15840ft


You define a strata name to search for in the drillholes selected along with the quality name and name of the grid file to use. The program processes each line in the list, taking into account only drillholes which have strata specified and calculating from the grid quality values for each zone. There is the option to draw the polylines, draw the hatch and skip the volume calculations. 

The command uses property lines to define the extent of the area of reserve. Nothing will be calculated if there is no property line present. The owner name associated with the property line will also be reported, making estimation of royalties an easy task. Optionally, the inclusion perimeter may be specified to limit area of calculations.

The results are shown as colored maps layerized by quality studied, with color changing based on the corresponding reserve class.
