Southern Arc Commences Drilling of Selodong CU-AU Porphyries
NOT FOR DISTRIBUTION TO US NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.
Vancouver, B.C.: Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce commencement of diamond drilling at the Selodong Porphyry Cu-Au Prospect located within its West Lombok Property, Indonesia. Several deep drill holes are planned to test lateral and depth extensions of previous Newmont drill intercepts within the Montong Botek and Blongas II porphyries, which are mineralised intermediate intrusions forming part of the Selodong Intrusive Complex.
The Selodong Intrusive Complex lies at the southeast end of a 13 km long, northwest trending structural corridor of mineralisation and alteration along which also lie the Pelangan Gold Prospect (see previous SA News Release 07-05) and the Mencanggah Epithermal/Porphyry District both also within SA's Property.
Newmont explored the Selodong area during the 1990s completing 7,956 m of diamond drilling within a 2 by 2.5 km area (Figure 1). Thirty-five of 52 drill holes intersected intervals of Cu-Au mineralised diorite-porphyry and volcanics. SA has obtained the drill core and digital database from Newmont and SA geologists have fully utilised these in their drill planning. (Summary intersections of the Newmont drilling are posted on the SA website)
Montong Botek and Blongas II are regarded as the best porphyry targets at this point and will be the focus of the initial drilling program. At Montong Botek 8 out of 13 drill holes were stopped in Cu-Au mineralisation (due to drilling limitations) and several intersected long intervals of significant Cu-Au grades. For example:
SGD001 366.2 m @ 0.24% Cu, 0.37 g/t Au from 2.0 m (composite of 3 mineralised intervals) PSG004 82.0 m @ 0.49% Cu, 0.73 g/t Au from 0.0 m PSG028 150.6 m @ 0.21% Cu, 0.42 g/t Au from 0.0 m and 3 of the drill holes exhibited increasing gold grade with depth:
PSG015B 75.8 m @ 0.40% Cu, 0.38 g/t Au from 75.0 m (inc. 15.8 m @ 0.64% Cu, 0.72 g/t Au from 135.0 m to end of hole) PSG018 141.5 m @ 0.37% Cu, 0.63 g/t Au from 14.0 m (inc. 52.3 m @ 0.58% Cu, 1.1 g/t Au from 103.2 m to end of hole) PSG018B 140.6 m @ 0.31% Cu, 0.51 g/t Au from 10.6 m (inc. 76.2 m @ 0.34% Cu, 0.70 g/t Au from 75.0 m to end of hole) At Blongas II 6 out of 10 drill holes ended in mineralisation and two deeper holes recorded long intervals of Cu-Au mineralisation containing high Au intervals:
SGD002 192.2 m @ 0.25% Cu, 0.54 g/t Au from 153.3 m (inc. 61.1 m @ 0.38% Cu, 0.93 g/t Au from 202.6 m) SGD003 285.0 m @ 0.19% Cu, 0.38 g/t Au from 154.8 m (inc. 67.1 m @ 0.29% Cu, 0.71 g/t Au from 267.4 m) Based on interpretation of geology and alteration mineralogies, the Montong Botek and Blongas II porphyries would appear to have suffered little erosion, hence there is good potential for preservation of the full mineralised system at depth.
Three other areas hosting porphyry style mineralisation (Blongas I, Kekalik, and Belikat) were also identified.
SA geologists have recently located three new areas hosting porphyry style mineralisation with supporting geochemical, alteration and ground geophysical anomalies within the western and northern parts of the prospect, and at least 7 other coincident geophysical/geochemical anomalies are currently being followed up within the Selodong Complex.
The Selodong Intrusive Complex possesses significant potential to host more porphyries and will be a major focus of exploration for the future.
