This zone with a somewhat circular shape is aligned in the NW-SE direction and is approximately 100 meters long. The inversion models show a low resistivity area in a depth of 60 m that can be related to a sulphidation zone. The geophysical survey in this work consisted of 6 lines of electric resistivity tomography in Wenner-Schlumberger array, of 520 m long and 10 m of space between the electrodes, arranged in a regular grid according to structural criteria previously established. The copper mineralization is housted in a metamorphosed, silicified and fractured sandstone with abundant presence of malachite and azurite in the fractured planes of the rock. In this paper are presented the results of the combination between a resistivity method and geological surface mapping, applied to the study of an area with potential mineralization of copper sulfides sited on the northern edge of the Camaquã sedimentary basin, Brazilian southern.
