    The depth to magnetic sources has been estimated from gradient inversion analysis of the acquired aeromagnetic magnetic data of Binji, north-western Nigeria. The study area is bounded by Longitude 4° 30’ E and 5° E and Latitude 13° N and 13°30’ N. The total magnetic field was separated into regional and residual fields using least squares polynomial fit, while twenty two (22) profiles of the residual magnetic fields were subsequently used to determine depth to magnetic sources. The depths vary from 0.22 km to 2.19 km with an average of 1.26 km. Since estimation of depth to magnetic sources is also regarded as a proxy for sedimentary thickness; the results showed that the sedimentary layer is not thick enough for hydrocarbon prospect and therefore confirm that petroleum exploration may not be plausible in the study area.
