A geophysical investigation has been done to identify resistivity variation zone of sulfide mineralization (gold) at Arinem-Papandayan. This investigation used secondary data of Controlled Source Audio Frequency Magnetotelluric (CSAMT) method. Processing data using software CMT-Pro and Surfer-9, resulting 2D modeling resistivity section. From the analysis and interpretation of 2D modeling resistivity section obtain that sulfide mineralization zone was found low resistivity (0??m-100 ??m) and medium resistivity (100 ??m-200 ??m) identify as argilic and silification alteration zones that spread into the NorthEast of investigation area. Electrical respon of rock in CSAMT also show high resistivity more than 1000 ??m in guess as andesite intrusion
