Southern Arc Update on Drilling Activity at Mencanggah Prospect
November 30, 2011 – Vancouver, BC – Southern Arc Minerals (TSX-V: SA) (“Southern Arc” or “the Company”) is pleased to provide an update on drilling at the Mencanggah Prospect on Southern Arc’s West Lombok Property, Indonesia.
Assay results have been received for drill holes MCG003 to MCG011, as summarized in Table 1 and Figure 1.
All intersections are reported as down-hole lengths. Assay results are pending for completed drill holes
MCG012 to MCG019, and six drill holes are currently in progress (MCG020 to MCG025).
At the Waterfall target, outcrops of banded and brecciated, epithermal chalcedonic-quartz veins have been tested with the objective of intersecting high-grade “boiling zones” at depth. Mineralization intercepted to date includes multiple vein zones with encouraging grades of up to 1.6 m @ 11.0 g/t gold and 2.6 g/t silver. The structural model for the area has been updated and drill holes currently underway are targeting favourable vein intersection zones.
Seven drill rigs are now operational at Waterfall with a total of 5,395 metres of drilling completed at Mencanggah to date. Three more rigs are expected to arrive on site this week. Upon completion of holes currently underway, the drill rigs will move north to the Bising and Tibu Serai targets. Surface channel sampling along the extensive strike lengths at Bising and Tibu Serai has returned high grade intervals up to 7.1 m @ 53.5 g/t gold and 5.0 m @ 12.2 g/t gold, as well as some very wide intervals of lower-grade gold mineralization up to 66 m @ 1.1 g/t gold.
Since re-commencing drilling at Mencanggah in October, Southern Arc has confined its drilling activities to the Waterfall target. Operational procedures have now been developed that will allow the Company to spread its drilling operations onto multiple targets as it advances toward its objective of completing National Instrument 43-101 compliant resource estimates for both the Mencanggah and Pelangan prospects in the first half of 2012.

The technical information in this document has been reviewed by Southern Arc’s Chief Geologist, Andrew Rowe, B. App. Sc. Geology, MAusIMM. Mr. Rowe has over 18 years of international mineral exploration experience throughout Southeast and Central Asia and Australia. During this time he has held such positions as Chief Geologist – Feasibility Studies, Senior Geologist and Consulting Geologist. The technical information in this document has also been reviewed by Southern Arc’s President & Chief Operating Officer, Dr. Mike Andrews, PhD, FAusIMM, who has sufficient experience relevant to the style of mineralization under consideration and qualifies as a Qualified Person as defined by National Instrument 43-101.
The drill program and sampling protocol is managed by Southern Arc under the supervision of Andrew Rowe. The diamond drill holes are drilled at PQ, HQ and NQ sizes depending on hole depth and core recovery to date has averaged 98.0%. Half core is cut by rock saw and is generally sampled using nominal 1 -metre intervals; however, sample intervals are varied according to geological contacts and have ranged between 0.2 to 2.5 metres in length. Three quality control samples (one blank and two standards) are inserted into each batch of 40 samples. The half core samples are securely transported from the project site to the Intertek Testing Services (“ITS”) sample preparation laboratory in Sumbawa Besar via private truck hired by Southern Arc. Sample pulps are then sent to the ITS Jakarta laboratory by ITS. Gold is analysed by fire assay with AAS finish and a four-acid digestion with ICP-MS finish is used to analyse a full suite of elements including silver and base metals. ITS is one of the world’s largest product and commodity testing, inspection and certification organizations. The Jakarta laboratory is ISO 17025 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.
