A Brief mineral investigation was carried out in the Tinjoan area, Sumatra Utara. This took the form of a drainage basin survey which was conducted at a time when the main target area (the Hatapang Granite( was being investigated by the project. No significant mineralisation was seen in the field or is indicated by the drainage basin survey

The survey area lies 90 Km northwest of Tapaktuan on the west coast of Sumatra in Aceh Province. A regional geological and mineralisation. The Susoh instrusion (late cretaceous to palaeocene in age)intrudes volcanics and limestones presenting the possibility of skarn-type mineralisation. Also the drainage basin survey had indicated copper anomalies …

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. In this investigation an area a altered granodiorite was surveyed by detailed drainage basin and rock sampling.
