A total of 663 rock geochemical samples were analyzed using Centered Log-Ratio (CLR) transformation, factor analysis (FA), and fractal modeling (C-A and LSA). Using remote sensing data, the indices Porphyry_Index and Epithermal_Index were generated and subsequently evaluated through fractal analysis. Structural features were analyzed using fractal dimension (D), allowing the inference of tectonic controls on mineralization. A total of 27 polygons were delineated, validating 13 previously proposed by Ingemmet and proposing 14 new ones (an increase of 107.7%). All polygons were cross-checked with Ingemmet field descriptions, which report the presence of ore minerals such as chalcopyrite, bornite, and native gold. Targets TRG_27 and TRG_18 stand out due to their high grades, reaching up to 3222 ppb Au and 8264 ppm Cu. The proposed approach is replicable and provides strategic value for modern mineral exploration.
