The research was carried out in Novo Mundo municipal, Mato Grosso State, Brazil, to mapping sulfate occurrence, using electrical sounding, induced polarization and magnetic methods . The results shows that only in the C profile the resistivity anomalies zones 1, 2 and 3 coincides with the apparent carbability anomalies zones, indicating greater probability of occurrence of sulfates. In the CD profile were evidenced anomalies zones of apparent cargability, however it does not exist resistivity anomalies zones in this profile, indicating lower probability of occurrence of sulfates . The magnetic method showed the existence of one anomaly, probably due of magnetic mineral. Considering the Induced Polarization and electrical sounding results the more probable locals to occur sulfate are in the C profile, in the zones anomalies 1, 2 and 3. Keywords: Mineral prospecting, magnetic, IP and electric sounding methods.
