The kr. Dusun area of Aceh Tengah has been the subject of several previous mineral investigations that have indicated the presence of mineralisation, possibly in the form of a molybdenum prophyry copper with associated lead-zinc mineralisation. This investigation has shown the Dusunintrusive complex is more extensively hydrothermally altered and tha…

A hydrothermally altered granodiorite containing molybdenite and chalcopyrte, dicovered by AMAX mineral exploration, has been investigated by rock and detailed drainage basin sampling. This well-exposed mineralisation is found in the Alue Moli, a small tributary of the Kr. Ise-ise, not far from the Takengon-Blangkejeren track, some 108 km south of T…
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.
