                         and the gold mineralization context of the Tapaj{\'o}s Mineral 
                         Province northwestern portion (Par{\'a} and Amazon states - 
                         Brazil).  Two regions were selected: areas of the Seta de Ouro and 
                         Chico Torres shear zones. Based on TM sensor, drainages were 
                         interpreted, beyond main lineaments. Using analytic signal 
                         amplitude and first vertical derivative images, magnetic 
                         lineaments and units were identified, like mafic dike swarms (~ 
                         180 Ma) characterized by NNE-SSW direction. The images of K, eTh, 
                         eU, K/eTh, K/eU, F parameter and of radioelement normalization 
                         were producing, beyond the color compositions. These products 
                         allowed the visual interpretation of the gamma-ray spectrometric 
                         units characterized by possible hydrothermal origin, and 
                         correlated with interpretation of structures identified by remote 
                         sensing. Other step utilized consisted in the gamma-ray 
                         spectrometric signatures extraction of the gold occurrences mapped 
                         by CPRM, and the application of the Principal Component Analysis 
                         to the enhancement of potential hydrothermalized areas. It was 
                         possible to enhance targets associated with the Seta de Ouro and 
                         Chico Torres shear zones, and characterized by N30W and N40W
