September 13, 2011 – Vancouver, BC – Southern Arc Minerals Inc. (TSX-V: SA) (“Southern Arc”) is pleased to report exploration progress at its Sabalong Project on Sumbawa Island, Indonesia. Under the option and joint venture agreement with a wholly- owned subsidiary of Vale S.A. (“Vale”) announced on October 4, 2010, Vale is solely responsible for funding all project expenditures and has funded approximately US$785,000 since December 2010 to complete mapping and surveying activities at the project. Vale must fund an additional approximately US$215,000 to complete Phase 1 funding requirements, and drilling is scheduled to begin in early Q4-2011.

The 9,950 hectare Sabalong Project is located in the Miocene volcanic belt of the Sunda-Banda Arc, 30km north-northeast of Newmont’s Elang copper-gold porphyry deposit, a “consolidated 25 Moz gold and 16 Blb copper target” (Newmont Mining Corporation News Release, February 24, 2011) and 75km northeast of Newmont’s Batu Hijau copper-gold mine. Geologic mapping at Sabalong has defined two main prospects. The Lito Prospect consists of massive vuggy silica outcrops enclosed by a 1.5km-diameter overprint of intense advanced argillic alteration in rhyo-dacitic pyroclastics (Figure 1). This is interpreted to represent a “lithocap” possibly indicative of a buried porphyry copper-gold system. Adjacent to Lito, the Toyang Prospect comprises a 2km by 4km northeast elongate area of hydrothermal alteration hosting epithermal veins.

During 2011 Southern Arc completed a detailed ground magnetic survey covering a 15.5 square km area over the Lito and Toyang prospects to identify potential buried porphyry targets. Magnetic anomalies identified on the western and southern margins of the Lito lithocap were recently covered by a deep- penetrating induced polarisation (IP) survey, which covered an 8.2 square km area. Inversion modeling and 3D visualization of the magnetic and IP data has revealed a chargeable zone over a 1.3km by 1.5km area possibly related to buried sulphides.

Southern Arc and Vale plan to drill this target with a series of deep holes to test for the presence of a mineralized porphyry system. The first three planned drill hole locations are shown in Figure 1. Southern Arc’s exploration team has issued a drilling tender and begun logistical planning activities at site in anticipation of an early Q4-2011 start date.

Southern Arc and Vale are exploring the Sabalong Project under an option and joint venture agreement whereby Vale can earn a 75% interest (Southern Arc retaining 25%) by funding project expenditures through to completion of a bankable feasibility study. To exercise its option, Vale must fully fund the advancement of either the Sabalong or East Elang projects (adjacent to Newmont’s Elang deposit) through to completion of a bankable feasibility study. Should Vale choose not to exercise its option, Southern Arc will retain its 100% ownership of both projects at no cost. Upon completion of Phase 1 expenditures at Sabalong, Vale may elect to solely fund a Phase 2 Minimum Program, involving at least US$2.0 million in exploration expenditures within two years. Additional details about the option and joint venture agreement are available on SEDAR at and on Southern Arc’s website at
