Deposit Type Commodi ty DL vs. Kriging (Recall) Drill Outcome Chile (Candelaria– PdC) IOCG, manto Cu 1.67× improvement 7.7 kT Cu verified; 11/11 holes hit HG Western Australia Orogenic lode Au 6x improvement, reconciled in drilling between 20232024 Improved, strongest in inconsistent MZ zones Economic Au confirmed in waste-classified zones Kazakhstan Orogenic lode Au 4x improvement 35koz Au verified; 11/13 holes hit HG The pattern across sites is consistent: DL resource estimation incorporating PSA-screened geological logging outperforms conventional Kriging at all three study sites. The magnitude of outperformance is positively correlated with geological logging data quality. The methodology did not require fundamental architectural modifications between deposit types—the same framework, screening approach, and evaluation protocol was applied in each case, with the PSA adapting input selection to the signal characteristics of local data.
