Rare earth deposit mapping: Kriging vs machine learning 2026 false-positive drill targets

Spatially leaked ML validation, not kriging smoothing, drives most 2026 REE false-positive drill targets; require blocked CV and kriging variance checks.

Abstract

Spatially leaked ML validation, not kriging smoothing, drives most 2026 REE false-positive drill targets; require blocked CV and kriging variance checks. Independent technical note mirroring the canonical version: https://skymineral.com/blog/rare-earth-deposit-mapping-kriging-vs-machine-learning-2026-false-positive-drill-targets.php Sources consulted: https://www.bluusun.com/
