Prior to the IAGMP the only significant gravity mapping of Irian Jaya Was undertaken byb the Nederlandsche Nieuw Guinee petroleum Maatschappij(NNGPM) from 1936 to 1960 as reported by visser and Hermes 1962. This pioneering Work Was undertaken as part of a search for oil and gas Was therefore largely restricted to areas of considered hydrocarbon pote…

The Kr. Dusun basin area has been subjected to several previous investigations that have indicated the presence of porphyry-style mineralisation plus the occurrence of some lead-zinc drainage basin anomalies. In this investigation an area a altered granodiorite was surveyed by detailed drainage basin and rock sampling.

These areas-Panomon, Kebyaran and keuretu -were suggested as follow-up targets on the basis of geochemical anomalies found during the regional geochemical survey of the north Sumatra Project (NSP).
