Geometallurgical Block Model: IDW Ore-Grade Estimation (2D)

2D block-model estimator: sparse drill-hole assays are spread across a grade grid with real inverse-distance-weighted interpolation, then classified ore vs. waste against an adjustable cutoff grade with a live tonnage and average-grade readout.

This 2D companion to the block-model plant walkthrough puts the actual geostatistics in front of you: a sparse set of randomly placed drill-hole assays feeds a real inverse-distance-weighted interpolation across a grid of ore blocks, a cutoff-grade slider reclassifies every block as economic ore or waste as you drag it, and the panel reports live tonnage and average grade for whatever gets called "ore" at the current settings — the same estimation math and cutoff economics that drive real open-pit mine planning, not a decorative color gradient.
