ABSTRACT The combination of Self Potential (SP), Electromagnetic (EM) and Resistivity profiling methods in Gwoza has resulted in the delineation of conductive zones suspected to be sulfide mineralization in the area. Mineralization potentials of –201 mV on the profile AA’, –250.2 mV on the profile BB’ and –203 mV on the profile CC’ respectively have been observed. Correspondingly, both the vertical coil and the horizontal coil readings of the EM anomalies on the profiles AA’, BB’ and CC’ also show significant negative anomalies across the delineated conductive zones. Three resistivity profiles DD’, EE’ and KK’ have also shown very low resistivity values across the said conductive zones. These conductive zones have been established as sulfide mineralization within faults in this work. The recovery of chalcopyrite samples from a hand-dug well close to the delineated conductive zone of the profile BB’ tends to lend credence to the interpretation in this study.
