Southern Arc Commences Airborne Geophysical Survey at West Lombok

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 6, 2011) - Southern Arc Minerals Inc. (TSX VENTURE:SA) is pleased to announce the commencement of a helicopter magnetic and radiometric survey over its entire West Lombok property. The survey plans to define both near-surface and buried copper-gold porphyry targets within the 13km by 7km Selodong-Mencanngah-Pelangan mineralized structural corridor. The detailed geophysical survey is being flown by GPX Surveys and will total some 2,420 line kilometres, with North/South oriented flight lines flown at 50m spacings over the entire property.

Newmont Mining, the previous tenement holder, flew regional airborne magnetic and radiometric surveys with line spacings ranging from 200m to 1000m. Southern Arc's magnetic inversion modeling of the Newmont data identified a number of near-surface magnetic anomaly targets. These magnetic anomalies coincide with structural intersections, locally elevated gold-copper-molybdenum soil geochemistry, and porphyry lithocap-related alteration assemblages that have been confirmed by clay spectral analysis. Geological mapping has also identified associated porphyry-style quartz stockwork veining at some of these localities. The combination of these features are interpreted as being related to both near-surface and deeper intrusive stocks with related porphyry-style alteration and mineralization. The detailed geophysical survey is expected to further refine these targets for drilling while identifying additional targets in the area.

The data acquisition phase of the survey is expected to be completed within the next 7 to 10 days and the new geophysical data will then be modeled and interpreted by leading geophysical consultants using state of the art processing methods. Southern Arc will also undertake Induced Polarization (IP) and resistivity ground geophysical surveys to further refine selected porphyry copper-gold targets that are to be drill tested in late Q4-2011, following the current drill campaign that is testing the strike length of gold-bearing epithermal mineralized structural breccia bodies at the Mencanggah prospect.
