Southern Andes Energy discovers additional high grade uranium mineralization on its Tupuramani project, Peru

“These new results significantly expand the exploration potential at Tupuramani by adding almost 4 kilometres of strike potential in five targets and all within 3 kilometres of our main Tupuramani discovery,” Nick Tintor, President and CEO of Southern Andes commented.

Highlights from reconnaissance trenching, channel sampling and pitting from these previously untested targets include:

• Pit K-10 on the Micha Michani #2 anomaly assayed 3,118 parts per million (“ppm”) (0.32%) U3O8 or 6.24 lbs U3O8 per ton. 
• Channel C-9 on the Condorillo #2 anomaly assayed 5,900 ppm (0.59%) U3O8 or 11.8 lbs U3O8 per ton across 1 metre. 
• A high of 1.68% U3O8 or 33.6 lbs U3O8 per ton across 0.6 metres in trench T-35 on the Condorillo #1 anomaly.

See the attached map for anomaly locations and the complete set of results in the tables below.

This year’s program was designed to follow up the 2010 reconnaissance work which outlined significant high grade uranium mineralization on the main Tupuramani anomaly which is believed to represent the westerly extension of the anomaly underlying the Colibri II-III uranium deposit owned by Macusani Yellowcake Inc. The Colibri II-III deposit has been reported to host NI 43-101 an indicated resource of 5.4 million lbs U3O8 grading 0.027% U3O8 and an inferred resource of 15.1 million lbs U3O8 grading 0.02% U3O8 at a 75 ppm U3O8 cut-off grade, according to information published by Macusani Yellowcake Inc. (See Southern Andes Press Release dated January 20, 2011).

The current program identified widespread uranium mineralization in all five target areas which correlate positively with high surface radiometric anomalies. Uranium mineralization occurs as fine disseminations of autonite and meta-autonite filling randomly oriented sub-vertical fractures and sub- horizontal fractures and disseminated in between fractures in flat lying ash crystal tuffs of the Quenamari Formation.

Results from the program are listed below.

Community, Social Relations and Drilling Plans

The Puno District in Southern Peru experienced a series of major protests last May and June which led to a disruption of services and exploration activities in the region. Despite the seriousness of the protests, Southern Andes Energy has always maintained positive relationships with the communities in our work areas and is pleased to report that the Company has signed Community Agreements with most of the communities in our operating areas. This also includes agreements with local private landowners.

With the signing of all relevant community agreements, the Company has submitted its Declaracion de Impacto Ambiental (“DIA”) with the Ministry of Energy and Mines and anticipates beginning a drill program in November. The DIA will allow the Company to construct up to 20 drill platforms with an initial 2,000-metre program designed to test all six targets in the Turpuramani project area.

QC/QA Protocols

Sampling consists of rock chip samples taken over lengths varying from 0.5 metres to 2.0 metres with each sample weighing approximately 1.5 to 3 kilograms. Assays were performed by CIMM in Lima, Peru, an ISO/IEC 17025 accredited laboratory, using a multi-acid digestion process. Sample preparation was completed by CIMM in Juliaca, Peru. A comprehensive Quality Control and Quality Assurance protocol has been implemented including the insertion of two blanks, two standards and three duplicates for each 100 samples processed.
