The mineral exploration is a complex activity that should involve a combination of direct and indirect techniques of geological investigation. The growing demand for base metals in the national and international market provides the revaluation of mineral occurrences that can become deposits and mines. This paper presents the results of the electrical resistivity and induced polarization geophysical methods in azimuthal arrangement, applied in a mineral occurrence of disseminated copper sulfides, previously studied through trenches and core drilling, located in the Camaquã Sedimentary Basin, Rio Grande do Sul State, Brazil. The inversion models indicate the coincidence of high chargeability and low resistivity values. The  integration of geophysical data permitted the elaboration of 3D attributes visualization models for the mineralization enclosed in volcanic tuffs. The integrated geophysical and geological analysis indicates the potential of a new mineralized area.

ABSTRACT. This paper discusses the results of the combined application of Electric resistivity and Induced Polarization methods into a mineral occurrence of manganese of supergenic origin, characterized by oxides of manganese and iron with terrain to powdery texture, arising from weathering of spessartite contained in metasediments.Keywords: mineral exploration, oxide, resistivity, chargeability, 3D modeling. RESUMO. Este trabalho discute os resultados de uso combinado dos métodos da Eletrorresistividade e Polarização Induzida numa ocorrência mineral de manganês de origem supergênica, caracterizada por óxidos de...Palavras-chave: exploração mineral, óxido, resistividade, cargabilidade, modelamento 3D.
