Availability of high resolution data is adequate in mapping subtler and low amplitude anomalies mapped in this study. Nine sheets of Aeromagnetic data was evaluated in order to estimate the depth to basement and to delineate lithological boundaries and structures responsible for hosting mineral resources. Depth slicing techniques were used to delineate the lithological boundaries and structures in the study area. Depth to basement estimation of the area for Standard Euler deconvolution ranges from 619.3m to 1748.9m for structural index (SI) of 0.5, for SI = 1, depth ranges between 719.8m and 1719.2m, for SI = 2, depth ranges between 416.9m and 1640.3m, for SI =3, the depth ranges from 623.0m to 1688.9m. The SPI depth result ranges from 351.1m (0.351.1km) for the shallow magnetic sources to 2207.2m (2.2072km) for the deep magnetic sources. Hydrocarbon may be recommended in some of the area since some of the area has appreciable thickness of sediments on the average. The geological structures in form of lineaments delineated serve as host to mineral deposit.
