SA Southern Arc Minerals Inc

Southern Arc Minerals (TSX VENTURE:SA)(OTCQX:SOACF) ("Southern Arc" or "the
Company") is pleased to announce the completion of a prospectivity study for
porphyry exploration targets on its West Lombok project. The study identified 17
new porphyry exploration targets throughout the property (Figure 1). Southern
Arc has commenced drill testing and will continue evaluating these targets with
detailed ground work.


Based on previous drilling conducted by the Company, Southern Arc considers the
West Lombok property to be highly prospective for mineralized porphyries.
Drilling during 2007 and 2008 on the Selodong prospect in the southern part of
the property returned significant porphyry-grade intersections including 363.50m
@ 0.3% copper and 0.5 g/t gold, and 102.25m @ 0.5% copper and 1.05 g/t gold
(Figure 2, Table 1) (refer to Southern Arc news releases dated June 28 and July
31, 2007). At Selodong, relatively deeper erosion has exposed mineralized
porphyries and it is inferred that at higher elevations northwest along the
mineralized corridor, advanced argillic alteration zones in the Mencanggah and
Pelangan prospects represent potential lithocaps to concealed porphyry systems.

Targets with moderate to high porphyry prospectivity occur in Montong Botek,
Blongas, Mahoni, Belikat and Makam Kedaro in the Selodong prospect; Bising,
Lendak Bare and Telekur in the Mencanggah prospect; and Batu Sendi and Lala in
the Pelangan prospect. A number of the targets have already had a limited amount
of drill testing (marked with black rings in Figure 1) and include the Montong
Botek and Blongas targets, which host zones of high-grade gold-rich porphyry
copper mineralization, supporting the outcome of the prospectivity analysis.


"The prospectivity study has identified valid porphyry exploration targets on
the West Lombok property based on conventional and contemporary wisdom on
porphyry / lithocap models," said Dr. Mike Andrews, Chief Operating Officer of
Southern Arc. "Southern Arc has a two-pronged exploration strategy at West
Lombok: to drill the more than 26-kilometer cumulative strike length of
epithermal-gold mineralization identified on the property, while exploring for
copper-gold porphyry systems related to the epithermal mineralization. While
Southern Arc awaits receipt of its Ministry of Forestry permit, the Company will
prioritize the porphyry targets to the southeast and northeast of the property
that are located in areas without forestry designation." 


The porphyry prospectivity study was completed by Dr. Steve Garwin, Southern
Arc's Senior Technical Advisor, with the objective of recommending new porphyry
copper-gold exploration targets within the West Lombok property. The study
followed 3D inversion modeling of results from a high-definition airborne
magnetic and radiometric survey completed in September 2011. The primary
objectives of the study were to review and interpret the results of the ongoing
regional geological mapping program; integrate geology and geochemical results
with the results of the recently completed airborne magnetics/radiometric
survey; and undertake a prospectivity analysis to generate porphyry exploration
targets. 


The prospectivity analysis was intended to determine primary pathway and focus
elements for hydrothermal fluid flow and ascending porphyry intrusions. Pathways
or inferred deep-seated structures were determined from coincident deep linear
features expressed in local geology, topography and the processed results of the
airborne magnetic survey images. Zones of increased structure abundance are
supported by a positive correlation with the major alteration zones, gold
fertile silica-ledges, quartz diorite porphyries and the margins of equigranular
diorite plutons. 


Elements indicating a primary focus for porphyry-intrusions are: 1) mapped
quartz diorites and dacitic porphyries; 2) the margins of pre-mineralization
equigranular diorite plutons; 3) potassium-deleted silica-clay alteration zones;
and 4) high-level magnetic bodies (potential mineralized porphyry stocks) that
occur along the margins of, or above, deep-level magnetic highs (potential
feeder plutons) (Figure 1). Pathway and focus elements were superimposed to
indicate the high probability target zones for ascending magma and developing
porphyry systems. 


Based on the results of the study, Southern Arc has initiated a program to drill
test the priority porphyry copper-gold targets.

prospects on the Lombok and Sumbawa islands in Indonesia, three of which are
being advanced in partnership with major mining companies Vale and Newcrest. The
Company's key exploration property is its West Lombok project, with several
gold-rich copper porphyry and epithermal gold vein prospects. Southern Arc is

Qualified Person 

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
Principal 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 98.6%. Half
core is cut by rock saw and is generally sampled using nominal 2 metre
intervals; however, sample intervals are varied according to geological contacts
and have ranged between 1.0 to 3.0 metres in length. Four quality control
samples (two blanks 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 AAS 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.
