N2 - The high gold commodity as well as the Pongkor production field that has existed since decades ago made it necessary to find a new potential zone for gold mining production. To find out the zone of gold mineralization and its continuity, geophysical studies then conducted by using the methods of Time-Domain Induced Polarization (TDIP) and magnetic. TDIP data consisting of resistivity and chargeability data are interpreted to determine alteration zones and subsurface mineralization that are correlated with magnetic data that has been inversed in 3D to obtain susceptibility parameters. Based on the value of resistivity in the study area, the argillic alteration zones are thought to has a value of < 50 Ohm.m. Silicification alteration zones supposedly have the value > 50 Ohm.m. The value of the chargeability at the mineralized zone indicated has a value of 100-810 msec. Also, study in the area of the mineralized zone have a susceptibility value in the range of -0.073 to -0.021 cgs. From that parameter of the mineralized zone, it is assumed that the mineralization zone is in the eastern part of the study area and oriented North-South direction with the orientation of the main fault.
