Gaining Greater Confidence in Your Block Model Estimates

By

GEOVIA GEMS™ and GEOVIA Surpac™ have been updated to include two important tools – Swath Plots and Grade Tonnage Plots supporting block model validation within the software solution.

Validation Plots

Validation plots allow geologists and engineers to quickly view charts of estimated values in their block models within the software. Charts launch in the Statistics Application are comparable to those available when evaluating point or drill hole data.

Swath Plots
The introduction of Swath Plots provides a useful and functional tool in the resource estimation workflow. This common validation  tool used amongst resource geologists and engineers alike help to provide a greater understanding of data trends in multiple orientations. Benefits include:

  • A quick method to validate the quality of an estimate by comparing the original mean sample grade to the estimated grade for a range of slices.
  • The option to apply weighted values assigned from the new declustering features.
  • The ability to view combinations of point, block or both point and block values.
  • An ability for mining geologists to quickly compare and validate the block model estimation compared to the raw sample data
  • Plots permit data to be analyzed in user-defined slices in both the Northing and Easting directions, as well as elevation, simultaneously.
  • On completion, reporting can be displayed externally in Microsoft Excel.

Grade-tonnage plots

The introduction of grade-tonnage plots strengthen the available tool set to rapidly interrogate and validate the size and grade characteristics or a mineral deposit; a common chart used by both geologists and engineers necessary for quick results and for legal reporting.

A Grade Tonnage plot displays the average grade versus rock tonnage, allowing geologists and engineers to quickly understand the effect of mining at different cut-off grades – typically, as the cut-off increases, the tonnage decreases. On completion, reporting can be displayed externally in Microsoft Excel.
