VANCOUVER, BRITISH COLUMBIA, Jan. 11, 2011 (Marketwire) --
Southern Arc Minerals Inc. (TSX VENTURE:SA) ("Southern Arc" or the "Company") is pleased to announce results from its first two holes of the Phase 2 drilling program at the Central Raja target, Pelangan Prospect.
Drillholes PLD001 and PLD002 intersected the Central Raja gold-bearing epithermal breccia zone at depth below the earlier shallow Phase 1 drillhole RDG01. RDG01 had returned an intersection of 10.70 m (true width 6.8m) @ 2.93 g/t Au (including 4.70m (true width 2.7 m) @ 5.80 g/t Au) previously reported. These new holes targeted depths of 60 m and 120 m below the RDG01 interval.
PLD001 and PLD002 intersected the following mineralized intercepts:
PLD001 4.85 m (true width 3.3m) @ 7.11 g/t Au 18.5 g/t Ag from 56.55 m
(including 1.35 m (true width 0.9m) @ 16.67 g/t Au 17.0 g/t Ag from 56.55 m)
PLD002 17.25 m (true width 5.7m) @ 5.73 g/t Au 11.7 g/t Ag from 121.60 m
(including 8.75 m (true width 2.9m) @ 10.51 g/t Au 20.7 g/t Ag)
Results from PLD001 and PLD002 support the concept of increasing gold grade with depth in Central Raja and confirm the existence of high-grade shoots within the system. They also highlight the need for further extensive deeper drilling at Pelangan.
"These initial results of Phase 2 drilling are very encouraging and highlight the significant gold potential not only at Pelangan, but also for the Mencanggah area. There, surface mapping and sampling of similar auriferous MSBs with an aggregate strike length in excess of 15 km have already identified a number of high priority drill-ready targets..." commented CEO John Proust.
The Pelangan gold prospect is located in the northwest section of a 13 km long, northwest trending structural corridor of epithermal and porphyry mineralization. This district-scale field also includes the Company's Selodong porphyry copper/gold prospect and the Mencanggah epithermal/porphyry prospect (to view Figure 1 click on: http://media3.marketwire.com/docs/SAFig1.pdf).
Surface mapping and shallow scout drilling at Pelangan defined extensive, structurally controlled, epithermal gold-bearing breccia zones (termed Mineralized Structural Breccia or "MSB") occurring over an area of 3 by 2 km. Five major zones of mineralisation (Raja, Kayu Putih, Tanjung-Jati, Lala and Ratu) have been delineated, comprising an aggregate strike length of approximately 4.6 km.
Phase 1 scout drilling during 2006-07 (51 shallow drill holes, 3,762 m) tested an aggregate strike length of approximately 3.5 km. Results from central and southern zones of Raja (to view Table 1 click on: http://media3.marketwire.com/docs/sa111t.pdf) (to view Figure 2 click on: http://media3.marketwire.com/docs/SAFig2.pdf), southern Kayu Putih and portions of Tanjung-Jati confirmed continuous of zones of gold mineralization over strike lengths up to 900 metres.
Phase 2 of drilling commenced in August 2008. This program was designed to test for down dip continuity of mineralization, sustained vein widths and the potential for higher grades at depth, (to view Figure 3 click on: http://media3.marketwire.com/docs/SAFig3.pdf). The Company is pleased to report very encouraging results from these first two holes on all three objectives.
The positions of the intersections in drill holes PLD001 and PLD002 are shown on the map (to view Figure 2 click on: http://media3.marketwire.com/docs/SAFig2.pdf), and in the long section presented in Figure 3 (to view Figure 3 click on: http://media3.marketwire.com/docs/SAFig3.pdf). Host rocks for the gold mineralized breccias comprise chlorite altered volcanic breccias and variably altered phyric andesites.
Drilling has identified a 'bonanza' episode within the Central Raja MSBs, characterized by significantly higher gold-tenor (generally greater than 10g/t), low silver/gold ratio, and specific vein textures. Such bonanza episodes can localize within the vein zone to form high-grade 'ore-shoots' which can add significant ounces to a deposit within relatively small areas.
The importance of such ore-shoots in epithermal systems are well illustrated by such examples as the 'Crown Shoot' from the Cracow Mine (Central Queensland, Australia: Newcrest Mining) where 400,000 oz Au were inferred from an approximate 200 by 300m area; similarly the 'Royal Shoot' at Cracow added a resource of 390,000 oz Au from an irregular 100 by 470m plunging elongate-shoot. An extraordinary example is from the Kencana K1 ore-body at Gosowong (North Maluku, Indonesia: Newcrest Mining) which contained 1.8 Moz gold from a roughly ovoid shaped 260 by 500m shoot, (information from Newcrest Mining Limited website).
Early recognition of ore-shoot controls such as structural intersections, favourable host lithologies, and distribution of high-grade surface material will aid in determining the 3-dimensional geometry and hence targeting of the bonanza-event within the mineralised structural breccias. Southern Arc will use this information to aggressively target and define potential ore-shoots with the aim of quickly developing the gold resources at Pelangan.
