FIFTEEN PORPHYRY CU-AU DRILL TARGETS IDENTIFIED WITHIN SOUTHERN ARC'S SELODONG PROSPECT
Vancouver, B.C.: Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that detailed geological mapping, geochemical sampling, scout drilling and newly completed studies by independent geophysical consultants, have defined 15 porphyry Cu-Au drill target areas within SA's Selodong Intrusive Complex (SIC). The Selodong Intrusive Complex covering an area of approximately 7 by 3 kilometres, is situated at the southern end of a 13 km long, northwest trending structural corridor of mineralization and alteration on SA's Lombok property.
Since April 2007, SA has completed four drill holes (SLD001 to SLD004) totaling 2,242.5 metres in the SIC area, with the fifth, SLD005 currently in progress. These holes have tested two of the 15 porphyry Cu-Au targets and all have intersected broad zones (363.5 to 442.2 metres) of significant Cu-Au mineralization. Within these intervals significant widths of high grade Cu-Au values were intersected and as such the SIC porphyry system would be classified in the "Gold-Rich" category of porphyry Cu mineralization. Details of holes drilled by SA in the SIC area are detailed in Table 1 below:

Due to the strong spatial correlation of elevated Cu-Au grades and secondary magnetite alteration recognized in drill holes, SA has commissioned geophysical consultants GRS of Brisbane, Australia to undertake modeling of ground magnetic data from the SIC area. Preliminary images from 3D geological/geomagnetic models by GRS confirm the potential for significant depth and size of the 15 targets.
These 15 distinct porphyry Cu-Au drill targets are located over an aerial extent in excess of 20 square kilometers. They show coincident magnetic highs associated with secondary magnetite alteration, elevated surface Cu-Au-Mo geochemistry and associated intense fracturing and vein stockworks typical of porphyry Cu-Au deposits. Six of these targets were scout drilled by the previous operator Newmont and this drilling has confirmed the model. The remaining nine target areas have yet to be drill tested. Details of each of these drill targets are shown in Table 2, whilst locations are shown in Figure 1.
Based on the encouraging drilling results to date and the large number of porphyry Cu-Au drill targets as detailed in Table 2, Management intends to drill test each target to better understand the geometry, grade, and size potential with the objective of prioritizing the targets for future work.
