Resource/Reserve Classification

The Resource/Reserve Classification command provides a report based on the area of each zone. The tonnage associated with each zone (Measured, Indicated, Inferred, and Hypothetical) can then be calculated using the Surface Mine Reserves command (found in either the Geology or Surface Mining module). The four classification zones have traditionally been based off of the following distances from a drillhole, but you can modify these distances to your liking.

The next step is to 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. The command uses property lines, or at the least, an inclusion polyline, to define the extent of the area of reserve. Nothing will be calculated if there is no property line or standard inclusion perimeter selected, and the following error will appear.

After selecting drillholes and a boundary line, the below dialog will appear. Here you can add a new strata layer to analyze with the Add button.

When adding a new strata to the list, the below dialog will appear.

Strata: This sets the name of the strata to analyze. Note that this must perfectly match the strata/bed name in the drillhole. When using bed names, it is important to include the Bed Name and the grouping suffix. For example, the above example shows the name that must be entered for the Key portion of the C1 bed (C1_KEY).
Quality: This is the quality attribute to analyze, such as thickness, BTU, etc. It is not required to enter a value for this field.
Grid: This is the grid name that has been created from the drillholes. It will compare these modeled values with the occurrences and spacing in the drilling.
Match Both Strata and Quality: This will make sure that the quality and strata name both are defined in a drillhole. If just the strata name is there, but no quality sample, then it will not be used as a sample point that is measured.
Inc/Excl Layer: These are the layers that the perimeters are drawn in.
Result Layer Prefix: This is a prefix it will put in front of the output layer names. The program will create layer names such as "_A_MEASURED" and "_B_INDICATED". If the prefix is set to "RSV", then the resulting layers would be "RSV_A_MEASURED" and "RSV_B_INDICATED".
Draw Polylines: This will draw the perimeter polylines that contain the hatching for the four classifications.
Draw Hatch: This will draw the hatching inside the perimeters and boundaries of classifications.
Skip Report: This option just does the CAD graphics and mapping only, not generating the report.
Assign Pit Names: This option will give a Pit Name to each perimeter, so it may be used for other volume calculations with commands such as Surface Mine Reserves.
Save Cut Set: This option will create a named cut set for the boundaries, which may be used with Surface Mine Reserves or the Timing commands to further divide volumes/tonnage into relevant categories. Note that when using Surface Mine Reserves or the Timing commands, you must enable the options to report by Property Boundaries to also use the cut set.

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