The Ilesha and Ado-Ekiti areas are characterized by extensive mineral potentials, including both metallic and non-metallic resources. To detect the probable zones of mineralization, airborne magnetic and radiometric data were applied to map lineaments and lithological components. o generate comprehensive structural maps, the Centre for Exploration Targeting (CET) grid analysis tool was applied to total magnetic intensity data upward continued to 100 m, First Vertical Derivative (FVD), Second Vertical Derivative (SVD), Analytic Signal (ASIG), Tilt Angle Derivative (TAD), and Total Horizontal Derivative (THD) grids. The structural maps strongly correlated with each other were observed to be characterized by polyphase deformations, and oriented in the NE–SW, N–S, and E–W directions. The dominant NE–SW trend is related to the Ifewara-Zungeru zone caused by the Pan-African Orogeny and other tectonic events. Distinct lithological areas were mapped using radiometric anomalies. A major lineament that falls within the potassium-rich and magnetically concentrated zone indicated possible igneous related gold site. In general, the lineaments that have been detected are probable hosts for metallogenic minerals. Furthermore, the depth estimate involving the Source Parameter Imaging (SPI) and Standard Euler Deconvolution (SED) detected thin sedimentation (≤ 482 m).
