Southern Arc Drilling Confirms Blongas I and II Targets as a Single Continuous Mineralized Zone as Seventh Drill Hole Intersects 245.10 metres @ 0.18% Cu and 0.22 g/t Au
Southern Arc Minerals Inc. (TSX Venture: SA) is pleased to announce that drill hole SLD007, located at the Blongas I porphyry Cu-Au target has returned a mineralized intersection of:-
245.1 m @ 0.18% Cu and 0.22 g/t Au from 175.5 to 420.6 m
This intersection included the following higher grade intervals:-
(32.9 m @ 0.22% Cu and 0.36 g/t Au from 177.5 to 210.4 m)
and (63.05 m @ 0.26% Cu and 0.26 g/t Au from 348.75 to 411.8 m)
SLD007 has confirmed the northward extension of Cu-Au mineralization intersected in SLD004, SLD005 and SLD006, approximately 250 metres north of these drill holes. The Blongas II and Blongas I targets are regarded to form one continuous mineralized zone.
SA's three previous drill holes into Blongas II returned the following previously reported broad intersections:
SLD004: 407.25 m at 0.25% Cu and 0.45 g/t Au from 160.25 m
(including 102.25 m at 0.50% Cu and 1.05 g/t Au from 176.55 m)
SLD005: 486.15 m at 0.22% Cu and 0.26 g/t Au from 2.00 m
(including 42.50 m at 0.39% Cu and 0.57 g/t Au from 200.40 m)
SLD006: 500.20 m @ 0.17% Cu and 0.30 g/t Au from 49.80 m
(including 174.70 m @ 0.22% Cu and 0.45 g/t Au from 200.20 m)
Drill hole SLD007 (Figure 1) was collared to the southeast of mineralization previously tested by Newmont at Blongas I, into a newly defined zone of quartz stockworking. SLD007 was drilled westward at an orientation of 290 degrees and an inclination of -65 degrees to a length of 586.6 meters. SLD007 was collared at an elevation 89 metres above the collar of SLD006.
For the length of drill hole SLD007 several generations of altered diorite intrusives hosting porphyry-style quartz stockwork veining were logged. These are observed to be cut by syn- and post-mineralization dykes of dacitic and dioritic compositions. The mineralized diorite intersected between 175 and 421 metres comprises a central potassic altered zone with phyllic overprinting increasing outwards.
As was noted in previous drilling at Blongas II, the potasically altered higher grade mineralization in SLD007 has been structurally faulted into an overlying phyllic halo, which indicates the potential for preservation of higher grade mineralization at depth and along strike of the areas drilled to date.
This intersection made by drill hole SLD007 defines part of a 2.0+ kilometre long, 250 to 300 m wide, open-ended structurally controlled corridor of porphyry style alteration and mineralization, which to date has been drill-tested along 600 metres of its length.
Drill hole SLD008 (Figure 1) is located 320 m north of the SLD007 and will test this corridor at an elevation 120 metres below the collar of SLD007. SLD008 was commenced on November 9, 2007 and is expected to be completed by early December. If SLD008 successfully intersects high grade Cu-Au mineralization, drilling will continue testing further north along the Blongas corridor.
