The structural depth interpretation of magnetic sources associate with gold and its proxy minerals was carry out in the western parts of Zamfara, Nigeria, using aeromagnetic data. The research area has been formerly explored for solid minerals using assortments of anaylsis, however there was no focus on the influence of enhancement filters such as the CET Porphyry on the depth and structures (Euler 3D) that houses gold and its proxy. This research subject the total magnetic intensity grid to produce Reduce to equator, residual grid, Tilt derivative, Lineament, Porphyry CET, Euler deconvolution and Source Parameter imaging. The Tilt derivative Map revealed the linear features (faults, fractures and shear zones) trending NS, NE and WE of the study area. The geological features that supports the existence of gold and associate minerals has been outlined clearly in all the maps. There are good similarities in term of geology, lineament and porphyry deposit maps of gold mines site and gold prospect zones. The result revealed six (6) prospect zones which are sunke of Anka area, Surimi of Bukkuyum, Mai iwa of Dangulbi, Birnin Magaji, Leshi and Gayawa of Gummi area. The Euler depth solution for contact/step models (Structural Index = 0) show the contact zone around Northern parts of Gummi, Anka and western part of Talata Mafara area between basement complex and sedimentary basin with an average depth estimated from 100m -700m. For the dyke and sill model of structural index 1, for Pipe and cylinder model of structural index 2 and sphere model of structural index 3 has shown a positive correlation with geology, lineament and porphyry maps of the study area. The solutions have clustered at places with major faults and fractures with an estimated average depth 100m – 700m that coincide with gold and associate minerals deposits.
