Abstarct: Recognition of target zones is one of most important stages in exploration of the deposits. Induced polarization and resistivity methods are useful methods in order to prospecting and exploring the sulfide mineralization. Dareh-Ashki area as study area, is one of nine known ore deposits of mouteh area of 150 kilometers. By considering sulphide mineralization evidences in Dareh-Ashki area, geophysics surveys were doing by four rectangular profiles with profile spacing of 50 meter and station spacing of 20 meter In order to survey hopeful anomalies in rectangular maps, four dipole – dipole profiles were designed; to investigate possible anomalies at depth. In order to survey hopeful areas in rectangular maps, four dipole-dipole profiles were designed to investigate possible anomalies at depth. Interpretation of dipole–dipole profiles data was done by RES2DINV software. Although Voxler software was used for 3D displays of IP and resistivity data. By comparing the results of rectangular profiles and dipole-dipole profiles interpretations, sulphide mineralization zones and therefore, possible auriferous zones were detected in area and according to these results, three appropriate locations for drilling were recommended. One drilling point on D01 profile with depth of 30 meter and two points on D02 profile with depth of 60 and 70 meter were suggested.
