6. VALIDATION STRATEGY Model validation was conducted using 60 known porphyry deposits in the eastern sector, excluded from the signature extraction to provide an unbiased test of spatial generalization. 6.1 Detection Criterion A deposit was considered detected if its location in the prospectivity map showed similarity ≥ 0.80, defining high-confidence anomalies resembling the learned porphyry signature. 6.2 Validation Results Using this criterion, 49 out of 60 deposits were successfully identified (82%). 7. RESULTS Figure 19 – Prospectivity map generated from similarity analysis between the porphyry latent signature and the study area.
