The Rio Grande do Sul Shield has its economic importance connected to the diverse gold and base metals mineralization that occurs in that area, such as Camaqua Basin, Cacapava, Lavras do Sul and São Sepé granitite intrusions. The region has been the subject of geological studies for a long time and several papers have been published about it, but they show great complexity for both the origin and evolution of the Shield and the mineral occurrences in it. The present study used a set of multivariate analysis for airborne geophysics and remote sensing data in part of the Rio Grande do Sul Shield, to verify the contribution of these techniques for the optimization of time and financial resources for the implementation of projects of mineral exploration. The results confirm that their use contribute to the discrimination of groups related to the described lithology in the area in a more clearly way that using these methodologies individually. Although the signatures of mineral occurrences have not been revealed, they can be used for their discrimination, based on the groups resultant from the analysis.
