SOUTHERN ARC DRILLS 192.25 METRE INTERCEPT GRADING 0.36% CU AND 0.74 G/T AU FROM ITS INITIAL DRILL HOLE AT BLONGAS II (SELODONG) PORPHYRY TARGET
Vancouver, B.C.: Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that drill hole SLD004 targeting the Blongas II porphyry Cu-Au target within the Selodong Intrusive Complex (SIC) on SA's Lombok property has returned:-
192.25 m at 0.36% Cu and 0.74 g/t Au from 160.25 to 352.50 m
(including 102.25 m at 0.50% Cu and 1.05 g/t Au from 176.55 to 278.80 m)
The drill hole was completed to a total depth of 605.0 metres and also intersected other mineralized intervals of:
39.90 m at 0.20% Cu and 0.29 g/t Au from 16.60 to 44.70 m
121.95 m at 0.21% Cu and 0.30 g/t Au from 399.55 to 521.50 m
The deeper intersections are included in broader zone of mineralisation which returned:
407.35 m @ 0.25% Cu and 0.45 g/t Au from 160.25 m to 567.50 m
Drill hole SLD004 (Figure 1) was drilled on a southwest azimuth at an inclination of -65o targeting extensions of Cu-Au mineralization previous intersected in drill holes SGD002 and SGD003 completed by Newmont. These returned:-
SGD002: 192.2 m at 0.25% Cu and 0.54 g/t Au from 153.3 to 345.5 m
(including 61.1 m at 0.38% Cu and 0.93 g/t Au from 202.6 m to 263.7 m)
SGD003: 285.0 m at 0.19% Cu and 0.38 g/t Au from 154.8 to 439.8 m
(including 67.1 m at 0.29% Cu and 0.71 g/t Au from 267.4 to 334.5 m)
The upper 85 m of SLD004 intersected sheared, phyllic altered dioritic intrusives, with localized stockwork veining and rare secondary copper minerals. From 85 to 160 m a post-mineralization hornblende diorite dyke was intersected. Variable secondary magnetite alteration, with associated porphyry-style stockwork and disseminated copper sulfide minerals are observed within diorite intrusives between 160 to 523 m. Post-mineralization diorite dykes cross-cut these intrusives from 352 to 390 m. Strong secondary potassic-altered feldspar porphyry intrusives were logged in the remainder of the hole.
SA's recent compilation of surface geological mapping, geochemical and geophysical results has developed 15 porphyry Cu/Au drill targets within the Selodong Intrusive Complex. Figure 2 shows the locations of porphyry drill targets developed to date.
To simplify drill hole nomenclature for such a large number of targets within the SIC, all SA diamond drill holes in this area will be given the Prefix SLD and unique numbers. Consequently, previously reported drill holes MB001, MB002 and MB003 have been renamed SLD001, SLD002 and SLD003 respectively.
Because of the strong spatial correlation of elevated Cu-Au grades and secondary magnetite alteration recognized in drill holes to date, SA has commissioned geophysical consultants GRS of Brisbane, Australia to undertake modeling of ground magnetic data from the Selondong area. All relevant surface and drilling data has been supplied to GRS, with the objective of developing 3D geological/geomagnetic models to focus ongoing drill targeting and exploration within the Selodong Intrusive Complex (SIC).
Drill hole SLD005, the second of three planned holes at Blongas II commenced on July 22, 2007 and is expected to be completed by mid August. This drill hole location is shown in Figure 1.
