Abstract

Gold mines in Indonesia are mostly still below the surface. Pacitan and the surrounding area is the part of Eastern Southern Mountain Range that has a lot of zones of alteration which appears on the surface, with some precious metal minerals were found. Ore minerals are found disseminated sulfide ore pyrite, arseno pyrite, chalcopyrite, enargite and malachite. From measurements of geomagnetic found high magnetic anomaly less than 700 nT surrounded by a low magnetic values and form a circular pattern, it is an indication of the pattern of anomalies of the porphyry system that is closed by the argillic. Based on data integration of geological and geophysical the mineralization in the Pacitan area in the interpretation were in the proximal part of the high sulfide and suspicion leads to the porphyry deposits are still covered by the lithocaps.
