Drilling has started at Southern Arc’s Sabalong project on Sumbawa Island. The company recently completed a detailed ground magnetic survey covering 15sqkm of the property to identify potential porphyry targets. 1

Magnetic anomalies identified on the western and southern margins of the Lito lithgocap were also covered by a deep-penetrating induced polarization (IP) survey. Inversion modeling and 3D visualization of this data revealed a 1.5 x 1.3km chargeable zone possibly related to buried sulphides. Southern Arc and its joint venture partner and subsidiary, Vale SA, plan to drill this target with a series of deep holes to test whether a mineralized porphyry system is present.

The Sabalong project covers 9950 hectares in the Miocene volcanic belt of the Sunda-Banda Arc, in the Nusa Tengarra Barat province about 22km south-southeast of the administrative city Sumbawa Besar. It is 30km north-northeast of Newmont’s Elang copper-gold porphyry deposit and 75km northeast of Newmont’s Batu Hijau copper-gold mine. It was previously owned by Newmont and Rio Tinto Zinc whose exploration and reconnaissance sampling confirmed gold-silver anomalous areas and base metal mineralization in the east.

Southern Arc acquired Sabalong in April 2007 and then entered into a joint venture with the world’s second largest metals and mining company, Vale SA. Vale will fully fund the advancement of Sabalong through to and including the completion of a bankable feasibility study.

The Canadian mineral exploration company has a portfolio of four projects with epithermal gold and gold-copper porphyry prospects on Indonesia’s Lombok and Sumbawa Islands.
