%X The Curaçá River Valley is economically important due to occurrences of mafic-ultramafic bodies containing cooper sulphide mineralization. The mineralization consists of copper sulphides with predominance of chalcopyrite and bornite. The sulphides shows unusual characteristics, as the high percentage of iron oxides associated, therefore the mapping of iron oxides can help to identify new copper mineralization targets. The integration of geophysical and remote sensing data supports a geological knowledge by analysis of physical properties of rocks, being used as a tool for mining exploration. Band ratio were achieved on RapidEye imagery, allowing the recognition of iron oxides index and has been integrated with airborne geophysical data, as magnetometry and gamma-ray spectrometry. The integration proved to be an adequate alternative for mapping iron oxides and recognize mineralized areas.
