Abstract : The study area spans from 4°30' E to 5°00' E in longitude and from 11°00' N to 11°30' N in latitude. A total of four profiles 400m long were surveyed using Wenner array configuration with minimal electrode spacing of 3m and repeated with integer multiple of 3 that explored up to 18m during which apparent resistivity values were found. Electrical resistivity tomography has emerged as a powerful geophysical technique for investigating subsurface structures, particularly in mineral exploration. This research explores the application of resistivity tomography in delineating basement structures associated with mineralization. Two-dimensional models were analyzed with the RES2DINV inversion software to achieve precise interpretations. The results revealed a range of geological features and variations at different depths. High resistivity zones indicated the presence of schist and moderately weathered gneiss with quartz veins, which are structurally controlled and oriented North- West and Northeast-Southwest. This technique proved effective in identifying potential mineral deposits, aiming to provide a comprehensive overview of the study area and improve mineral exploration strategies through resistivity tomography.
