As a Geologist, you may be asked to produce a contoured gram meter plot to outline areas of the ore body that have the greatest value or potential ore shoots. This plot can also highlight areas of wider stopes, that then require more ground support during mining. This plot can also highlight areas where more drilling is required to upgrade the resource/reserve.

This is the 3rd post in the series “plotting long sections”. The files created in the 1st article, from the functions “Database>Composite>by Geological Constraints” and “Database>extract>zone thickness and depth” are required for this process.

In this second part post we continue on with the plotting of the Puncture Plot, but we will use entities to display the drillhole ID, grade and true width and how to display a legend.

As an underground geologist, one of your job’s may be to create a long section puncture plot of the ore body drill-hole intercepts displaying the grade and true width.

This plot can then be used to help monitor the grades while mining, and to assist in the design of infill drilling programs to upgrade the resource-reserves.
