    A conventional D.C VES Survey was carried out in Government Day Secondary School Site, Maikunkele, Minna, Niger State, Nigeria. It lies between 09⁰40’37.17” to 09⁰41’37.15”N latitudes and 06⁰29’51.66” to 06⁰30’51.55”E longitudes in the basement complex region of Nigeria. The survey was carried out with the aim of evaluating the groundwater potential of the surveyed region and to locate suitable site for productive borehole development in the study are. The technique used in this research is the Vertical Electrical Sounding using Schlumberger configuration. A total of 30 VES points were located on grid profiles separated at 100 m interval between profiles. The data acquired from the survey were subjected to geophysical interpretation with the help of a computer based program called WinResist. The result acquired from the 5 profiles were analysed and contoured to produce the resistivity contour maps and iso-resistivity contour maps for the surface and the basement. The interpreted layered-earth model suggests the existence of two geo-electric regions. The weathered basement is considered as the bearing zone (aquifer) and is generally characterized by relative resistivity values of 100 Ωm to about 485 Ωm and aquifer thickness ranging between 3 m to 20 m. The Southern and Northern part of the study area are the most promising regions for sinking boreholes to derive underground water. The high resistivity distribution at the Southern to North central parts of the study area could be attributed to laterite deposit at the surface of the region where00as the Northeast and North-western corresponds to area delineated as having shallow basement.
