Uncertainty isn’t the enemy — it’s something to quantify and manage.
Kriging variance, conditional simulation, and data spacing all reveal where uncertainty lives.
This image visualizes the Kriging variance across a deposit, which is a measure of the uncertainty in the estimated value at unsampled locations. In the context of a geological deposit, areas of:
- Low Variance (often represented by cooler colors like blue) indicate a higher confidence in the estimated mineral concentration or thickness, typically close to sampling points.
- High Variance (often represented by warmer colors like red) indicate lower confidence or greater uncertainty in the estimated value, usually in areas far from sample data or where the geological variability is high.
This map is a critical tool in geostatistics and mine planning as it helps engineers and geologists decide where to place additional exploratory drill holes to reduce estimation risk and improve the overall resource model.
A good geologist doesn’t hide it — they map it.
