Abstract: Due to non-availability of records of essential pre-drilling investigations and drilling data of Boreholes’ installations at Igboora Town and its environs, it is difficult to manage and develop the groundwater resource which is the main water supply for the entire inhabitants. The present investigation used the conventional electrical resistivity geophysical method to characterise the weathering and bedrock fracturing, and to reveal the water conductance potential of the Basement crust of Igboora areas of southwestern Nigeria.
