Abstarct: Today, the use of geophysical methods for the exploration of mextallic and non-mextallic deposits is common. Inductive polarization (IP) and electrical resistivity (RS) methods have a special place in order to identify and explore areas of dispersed mextal and sulfide mineralization. Geophysical surveys using special strength and IP methods in this study were conducted in Navid region of Yazd province. These withdrawals were made to identify and explore copper in the area. In some parts of the study area, the effects of copper and iron mineralization as a result of the effect of hydrothermal solutions on dacite rocks of the studied unit and their alteration can be seen. Extensive outcrops of chalcocite, chalcopyrite, colitis and burnite can also indicate significant mineralization in the region. In order to identify promising areas, geophysical operations were performed by IP method and electrical resistivity in the study area. In this regard, three diagonal profiles (northwest - southeast) with an electrode distance of 20 meters with a dipole-dipole array were designed and implemented. Then two-dimensional inverse modeling of resistivity and IP data was performed by RES2DINV and ZONDRES2D software. Using geological information, the sections obtained from inverse modeling were interpreted on the resistivity and IP data by the mentioned software. According to the obtained results, copper mineralization zones have high load capacity and high to medium specific strength. Finally, by identifying the promising areas of the area for further studies, suitable locations for drilling exploratory boreholes were introduced and suggested.
