The research work investigated the Hydro-geological and mineral potentials of an area of 1.0 by 1.2 kilometers. A reconnaissance survey of the area was carried out using anomalous field of the aero-magnetic intensity data covering the area. The second vertical derivative reveals structures trending in the NE – SW direction, major magnetic distortions where observed within the North-eastern and Southwestern corner of the study area. Features that could be interpreted as fractures and fault-line pre-dominate these regions, this result was used as a guide in determining the trend for the profile in other geophysical methods, which are seismic reflection, Vertical Electrical Survey, and VLF Six profiles was employed for seismic tomography with shot point intervals of 250 m. using the equipment, 36 shot points was investigated using RAS 24 seismograph equipment, at a separation of five (5 m) and an offset distance of 5 m, in a forward and reversed directions along each profile line. The result show that the area is generally underlain by two geologic formations, that is, over-burden and basement formations. With average over-burden layer velocity of 879.99 m/s, with highest value of 2578.87 m/s at B6 and lowest value of 256.89 m/s at E3. Second or refractor layer having average velocity value of 2792.12 m/s with highest value of 8160.17 m/s (B6) and lowest value of 651.26 m/s (B1). Finally the area has average over-burden thickness of 22.41 m, with highest value of 36.57 D3 and lowest value of 12.94 m C2.
