VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/25/13 -- Southern Arc Minerals (TSX VENTURE: SA)(OTCQX: SOACF) ("Southern Arc" or "the Company") is pleased to report encouraging drilling results from the Tibu Serai target at Mencanggah on Southern Arc's West Lombok property, as well as the commencement of a further phase of drill holes testing both epithermal gold and porphyry copper-gold targets on the property.
Seven shallow drill holes have been completed (1,124.2 m) at Tibu Serai to test down dip from high-grade surface channel samples (Figure 1 and Table 1). Highlight intercepts include:
MCG055 24.8 m @ 4.27 g/t gold and 0.6 g/t silver from 48.6 m including 0.5 m @ 71.0 g/t gold and 1.9 g/t silver from 49.4 m and 5.4 m @ 9.44 g/t gold and 1.3 g/t silver from 67.2 m including 0.55 m @ 71.0 g/t gold and 6.8 g/t silver from 71.75 mMCG050 10.77 m @ 1.01 g/t gold and 4.0 g/t silver from 100.23 m including 2.15 m @ 3.87 g/t gold and 17.0 g/t silver from 108.85 m including 0.5 m @ 15.0 g/t gold and 67.4 g/t silver from 110.5 mMCG051 8.7 m @ 1.56 g/t gold and 0.71 g/t silver from 114.7 m including 3.5 m @ 3.33 g/t gold and 1.0 g/t silver from 119.9 m 8.85 m @ 0.74 g/t gold and 0.4 g/t silver from 136.45 mMCG049 12.1 m @ 1.07 g/t gold and 1.2 g/t silver from 31.3 m including 4.2 m @ 2.17 g/t gold and 1.7 g/t silver from 34.65 m 3.3 m @ 1.21 g/t gold and 1.2 g/t silver from 78.7 m
These results confirm the down dip continuity of mineralization below surface at Tibu Serai. The seven widely spaced drill holes have tested only a fraction of the strike of the mineralized breccias at Tibu Serai and many zones of highly anomalous surface sampling remain to be tested.
Drillhole MCG055 is particularly encouraging as this mineralization lies adjacent to an inferred major cross-cutting structural break evidenced from the magnetic survey data and mapped outcrop patterns. Southern Arc's exploration team believes this major structural break may be influencing higher gold grades in its proximity. Several other anomalous vein targets lie adjacent to this feature and represent encouraging targets for future exploration.
Tibu Serai comprises a 2 km by 2 km area at the northern end of the Mencanggah prospect and hosts numerous northwest and north-northwest trending linear gold mineralized structures. The majority of these well-exposed mineralized zones have been systematically channel sampled and have returned numerous highly gold-anomalous intervals. Highlight channel samples include 7.1 m @ 53.53 g/t gold, 2.25 m @ 12.13 g/t gold, 0.6 m @ 69.0 g/t gold and 2.0 m @ 9.8 g/t gold.

A review of drill results from the Bising and Tibu Serai targets has indicated that additional drilling is warranted in both these areas.
A further three drill holes are planned at Tibu Serai to test extensions of the high-grade intercept observed in MCG055. Two holes will step out 40 meters either side of MCG055 to test mineralization along strike, and one hole will drill below MCG055 to test whether mineralization continues at depth. These holes will allow for interpretation of potential high-grade shoot geometry and help to determine the role of proximal cross-cutting structures in controlling such shoots.
