A Geovariances Case Study
Geovariances worked with a top-ten aluminum producing company that needed to determine how many drill holes were necessary to support reliable resource classification at different confidence levels. The company wanted a way to optimize its drilling pattern while maintaining confidence in measured and indicated resource estimates, and Geovariances used conditional simulations in Isatis to address this challenge.
Using Geovariances’ simulation-based methodology, the company evaluated uncertainty across different drill hole spacings and production volumes. The study showed that a 150x150m pattern was sufficient for Measured classification and 250x250m for Indicated, meaning the company could achieve reliable classification with only 75% of the holes it had typically drilled, reducing drilling campaign costs by 25%.
