Vancouver, B.C.: Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that drillhole SLD005, SA's second drillhole into the Blongas II porphyry Cu-Au target, has returned mineralized intersections of:-

486.15 m at 0.22% Cu and 0.26 g/t Au from 2.00 to 488.15 m

This interval included the following higher grade intersections:

72.10 m at 0.38% Cu and 0.30 g/t Au from 97.70 to 169.80 m

42.50 m at 0.39% Cu and 0.57 g/t Au from 200.40 to 242.90 m

80.00 m at 0.19% Cu and 0.42 g/t Au from 334.60 to 414.60 m

Blongas II is the second of fifteen porphyry copper-gold targets within the Selodong Intrusive Complex to be drill tested. The Selodong Intrusive Complex occupies an area exceeding 20 sq km located within the western part of SA's Lombok property.

SA's first drillhole into Blongas II (SLD004) returned the following, previously reported intersection:

407.25 m at 0.25% Cu and 0.45 g/t Au from 160.25 to 567.50 m

Drill hole SLD005 (Figure 1) was drilled eastward at an inclination of -65o to a length of 565.6 metres. SLD005 proved lateral and depth extensions of Cu-Au mineralization previously intersected in Newmont's drillholes SGD002, PSG002 and PSG002A.

The upper 241 m of SLD005 intersected a series of altered diorite intrusives hosting porphyry-style quartz stockwork veining and secondary magnetite. From 172 to 200 m a post-mineralization hornblende diorite dyke was intersected. A fault-sliver of volcanic country rock, with metasediment equivalents, was logged from 241 to 252 m. Intrusive rocks logged between 252 and 540 m show variable secondary magnetite alteration and porphyry stockworking, overprinted by phyllic alteration. Intense phyllic alteration of intrusive units is prevalent for the remainder of the hole. Shear/fault zones often tens of metres wide were intersected throughout the majority of the hole, confirmingthe dominant regional N to NW trending structural regime. 
Results from drillholes SLD004 and SLD005, earlier Newmont drillholes, and detailed geological mapping recently completed by SA's geologists indicates that a N to NW trending structural corridor through Blongas I and II is host to a zone of porphyry copper-gold mineralization approximately 280 m wide and 1000 m in length. This zone coincides well with mapped surface exposures of porphyry-style stockworking, Cu-Au-Mo soil geochemistry and linear magnetic highs associated with secondary magnetite alteration. A number of future drill holes will test the depth extent and grade of mineralization along the strike length of this newly identified zone.

Drill hole SLD006 located 200 m north of the outcrop of the Blongas II intrusive was commenced on August 22, 2007 and is expected to be completed by mid-September. This drillhole location is shown in Figure 1.
