An efficient method in exploration of sulfide minerals (i.e. Cu Skarn and Porphyry deposits) is the application of geoelectrical techniques including the induced polarization (IP) and the electrical resistivity (Rs). As 2D electrical modelling presents an image of anomalies in depth, but for detail imaging of anomalies it is not as efficient as 3D modelling. 3D modelling of IP-Rs surveys results accurate view of anomalies which borehole suggestion for detail exploration would be easier. In this paper, three-dimensional modeling of Ghalandar Cu-Fe deposit has been prepared. According to skarn type of Ghalandar deposit and paragenesis of copper and iron, after different exploration studies such as, geochemistry, geology, and magnetometery, 10 IP-Rs profiles have been survived in north – south direction, then their 3D modelling result have been compared with 3D grade estimation modelling from16 boreholes results.
