Vancouver, B.C.: Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that the second diamond drill hole (MB002) at its Montong Botek porphyry Cu-Au target has intersected more encouraging copper--gold mineralization. The Montong Botek porphyry forms part of the Selodong Intrusive Complex (SIC), which is situated at the southeast end of a 13 km long, northwest trending structural corridor of mineralization and alteration along which also lie the Pelangan Gold Prospect and the Mencanggah Epithermal/Porphyry District, all within SA's Lombok Property.

Drill hole MB002 was completed at a total depth of 518.0 m. Following the first 18.1 metres, which was not mineralized, drilling intersected:-

384.65 m at 0.30% Cu and 0.40 g/t Au from 18.1 to 402.75 m (including 117.2 m at 0.56% Cu and 0.80 g/t Au from 118.7 to 235.90m) 

This intersection is interpreted as being an extension of the same high-grade porphyry Cu-Au mineralized zone that was intersected in drill hole MB001, which returned:-

442.2 m at 0.28% Cu and 0.42 g/t Au from 33.8 to 476.0 m (including 105.0 m at 0.60% Cu and 1.04 g/t Au from 33.8 m to 138.8 m)

Results from Drill hole MB001 were previously reported in SA news releases 07-13 and 07-14 dated May 10, 2007 and May 11, 2007, respectively.

Drill hole MB002 was drilled at an inclination of -60o in the opposite direction of drill hole MB001 to determine the south western extent of the mineralization (Figure 1).

The first 335.0 m of MB002 intersected moderate to strong stockwork porphyry veining hosted by a number of quartz diorite intrusive phases and associated brecciation zones. Around 335 m the diorites appear faulted against a chaotic, polymictic diatreme breccia, which continues to a depth of 478 m. This breccia exhibited a variety of hydrothermal textures and structures. Basement rock comprising recrystallized limestone with lesser tuffaceous horizons prograding into marbles and later garnet-epidote skarns was logged from 478 m to the end of the hole.

Drill hole MB002 further highlights the potential for extensive porphyry Cu-Au mineralization within the Selodong Intrusive Complex. 

Newmont previously explored the Selodong area during the 1990s, completing 7,956 m of diamond drilling within a 2 km by 2.5 km area. Thirty-five of 52 drill holes intersected intervals of Cu-Au mineralized diorite-porphyry and volcanics. SA has obtained the drill core and digital database from Newmont and SA geologists have fully utilized these in their drill planning.

Hole MB003 has commenced targeting eastern and southern extensions of the Cu-Au mineralization intersected in MB001 and MB002 and is expected to be completed by early June
