Delineation of mineralization zone using Aeromagnetic data, sheet 125 (Dutsen -Wai) of NE part of Kaduna state. The result was delineated tom identify areas with high potential for cassiterite deposits by locating potential host structures, lithological contacts, and magnetic susceptibility contrast that give inside on the distribution of this mineral in prospect. It was obtained using quantitative techniques such as Euler Deconvolution and spectral analysis, the Euler deconvolution with a structural index of 1 and 0 for dyke mapping and contact respectively. The spectral analysis was used for the depth to the magnetic sources model for both regional and the residual anomaly sources, and all the results were incorporated with the geologic map of the area to map out the prominent structures and determine their depth and tend of those potential structures found within the host rock which is identified as the biotite granite. Three potential areas were identified from the interpretation and are mapped out on the geologic map around the host rock which is of Biotite granite component of the area.
