Abstract

By combining the results of the two geophysical techniques in parts of Gidan Waya Kafancha Kaduna State, numerous linear structures, possibly veins harbouring ore mineralisation, were discovered. These veins have varying electrical characteristics, some being conductive and others being non-conductive. Furthermore, certain veins are conductors within a resistive host, whereas others are located within a conductive host. The research region had approximately 30 conductive bodies(veins), most of which trended north-south direction and ranged in length from less than 25 meters to more than 150 meters. These discovered veins were shown on mineral prospecting maps. After careful consideration, 30 locations were chosen for the prospective ERT/IP survey generated from the EM-VLF, and 25 drilling points were derived from the ERT/IP dataset obtained from the inversion model, which is the priority drilling point.
