The math is deterministic; the ore is not. Statistics bridges that gap. Statistical Methods For Mineral Engineers

Amaya also insisted they look beyond grade. Bulk density varied with lithology. Recovery rates depended on mineral liberation characteristics the assays didn’t capture. She introduced multivariate techniques: principal component analysis to summarize correlated geochemical indicators and co-kriging to incorporate secondary variables where appropriate. For zones with scarce sample density, they used indicator kriging to estimate the probability of crossing critical thresholds rather than trying to estimate a precise mean.

Leveraging multivariogram and variographic analysis to filter noise and summarize essential variability information. Bulk density varied with lithology

: It provides tools to determine if process changes (e.g., new collectors or cyclone configurations) actually improve performance or if the observed variations are just "noise".
