VANCOUVER, BRITISH
COLUMBIA--(Marketwire - July 10, 2008) - Southern Arc Minerals Inc. (TSX
VENTURE:SA) announces the results of drill hole SLD023 at the Montong
Botek target, drill hole SLD022 at the Blongas II target, and SLD021 at
the Lapangan Geres target, all located at the Selodong porphyry Cu-Au
prospect on west Lombok Island, Indonesia.
SLD023, drilling the northern extension of the Montong Botek porphyry
target, has returned the longest mineralized drill intercept on the
property to date with:
855.10 m at 0.10% Cu and 0.22 g/t Au from 0.00 m to 855.10 m
including: 242.00 m
at 0.18% Cu and 0.41 g/t Au from 210.00 m to 452.00 m
and: 100.00 m
at 0.26% Cu and 0.70 g/t Au from 278.00 m to 378.00 m
Montong Botek
The SLD023 broad intercept confirms continuity of Cu-Au grades at depth
and indicates the mineralized strike potential further north. Drill
hole SLD023, the second of two deep holes completed at Montong Botek,
was located at the previous SLD013 drill pad to test an inferred
northerly plunge of Cu-Au mineralization, as suggested from previous
drill intercepts in holes SLD001, SLD002, SLD011, SLD013, SLD017 and
SGD001 (Figure 1).
SA and historical Newmont drilling has partially defined an open-ended
north-south elongate Cu-Au mineralized zone of 450 m long by up to 200 m wide at Montong
Botek. This north-south trending mineralized zone lies within an area
defined by SA drill holes SLD011, SLD013, and SLD023 in the north and
shallow Newmont drill holes PSG012 to PSG014 and PSG017 to the south.
SLD023 was drilled eastward at an inclination of -70 degrees to a depth
of 871.0 m.
From surface to a depth of 592.0 m polymictic breccia comprising
mineralized quartz-diorite (QD1) and altered diorite clasts were
logged. Narrow diorite dykes intrude the breccia between 364.0 to 366.0 m and 529.0
to 561.0 m.
From 592.0 m
until the end of hole altered volcanic and volcanic-derived sediments
were encountered.
Blongas II
SLD022 was drilled 150
m south of SLD005 at Blongas II to test for
potential southwest extensions of high grade mineralization previously
intersected in SLD004: 407.25
m @ 0.25% Cu and 0.45 g/t Au, including 192.25 m @ 0.36%
Cu and 0.74 g/t Au (Figure 1). The drill hole
rationale was based on elevated Cu-Au soil geochemistry at this
locality. However, no significant mineralization was intersected in the
drill hole.
Lepangan Geres
SLD021 was drilled at Lepangan Geres, the most northerly porphyry
target within the Selodong Intrusive Complex, approximately 7.5 km along strike
of the same N-NW structure that hosts the Montong Botek and Blongas
I-Blongas II porphyry targets. It comprises a north-trending,
open-ended 600+ m long by up to 300 m wide zone of discontinuously
exposed porphyry stockwork and sheeted vein zones hosted within altered
diorite porphyry intrusives and altered volcanics. The area is on the
edge of a large circular magnetic "high" and at the
intersection of regional N-S and E-W fault structures. Surface sampling
has returned intersections including 80 m @ 0.22 g/t Au
(incl. 20 m @ 0.11% Cu/0.30 g/t Au), 55 m @ 0.31 g/t Au and
20 m
@ 0.33 g/t Au respectively.
SLD021 returned a low tenor Cu-Au intersection
of:
142.55 m at 0.07% Cu and 0.14 g/t Au from 0.00 m to 142.55 m
SLD021 (Figure 2) was sited in the centre of the main diorite porphyry
body to test shallow to moderate depth extensions of surface porphyry
Cu-Au mineralization within the inferred north-south structural
corridor.
SLD021 was drilled eastward at an inclination of -70 degrees to a depth
of 521.00 m.
From surface to 198.0
m intensely sheared, phyllic altered diorite
porphyry intrusive hosting weak to moderate amounts of quartz-sulfide
stockworking (QD2 phase) were logged. For the remainder of the hole (198.0 to 521.0 m) sheared
volcanics and volcanic sediments were intersected. A late-stage diorite
porphyry dyke was noted in core from 466.5 to 478.2 m. Overall, the drill core is highly sheared and
fractured, typical of drilling across the structural grain of a major
fault or fracture zone.
