Abstract: The aeromagnetic survey of Isi-Uzo was conducted by Nigeria Geological Survey Agency. 305,669 numeric data points make up the entire amount of Isi-Uzo data points. These data points were digitally captured (X, Y, Z text file) following the removal of the geomagnetic slope from the initial data set using the International Geomagnetic Reference Field (IGRF). Through the use of source parameter imaging, that was examined using Oasis montaj software, the depths of the magnetic source body were determined. The research area’s magnetic intensity varies between -74.72 to 147.24 nT, at its lowest and maximum levels, respectively. There could be a dip or plunge, change in lithology, change in depth, variation in magnetic susceptibility, or angle of strike causing this fluctuation in magnetic strength. The SPI depth value varies with a minimum of 151.6 m for shallow depth magnetic bodies to a maximum of 3082.7 m for deep lying magnetic things. Thick sedimentation for hydrocarbon formation and mineral deposit is seen at depths ranging from 1200 m to 3082.7 m whereas shallow depths of 35 m to 150 m which are evident of excellent prospective sources of water. This work gives information that will be very important in mineral exploration and management for economic growth in the area.
