Survay IP methods to detect mangan mineral’s ditribution carried out at 3 location in Lombok, West Nusa Tenggara. Data acquisition of the IP survey use Scintrex that consist of Motor Generator TSQ-4, Transmitter Control TSQ-3 and Receiver Time Domain IPR-12. Survay at 3 location during 12 days, at November 18 to 29, 2006. First, the IP data processed with moving average , result resistivity and chargeability curves at the lines, to find initial position of mangan deposit. The furthermore steps is modelling with RES2DINV programs, to find true resistivity and chargeability at the line and pseudosection contour’s. Interpretation from true resistivity and chargeability pseudosection contour combine with geologic information at the area, distribution of mangan deposit at various shape. Some is the big deposits and the other at many small deposit. The deposit calculation all lines at the area base on the IP interpretation. The mangan deposit at Location I is 176.450 ton, Location II is 63.500 ton and Location III is 44.700 ton. Keywords : metode IP, mangan, chargeabilitas, resistivitas
