Sierra Inesperada is located approximately seven kilometers southwest of the
A mineralised structural corridor was identified, which is oriented N60 W / 85 SW, with a thickness that varies between 5 and 40 meters and an interpreted depth greater than 150 meters and strike of 200 meters. The structures have brecciated textures with fragments of gray quartz, vuggy silica and lithics. The wall rock is affected by an advanced argillic alteration with moderate to intense silicification and a strong presence of alunite.
The oxidation zone is recognized by the presence of iron oxides that mostly correspond to hematite-jarosite and traces of copper oxides. The sulphide zone is clearly represented by the weak to high presence of disseminated pyrite in irregular veinlets. Gray sulphides are observed as enargite and traces of chalcocite, which are arranged as a very thin patina in the pyrite.
The host rock of the mineralization corresponds to a pyroclastic sequence formed by layers of tuffs and lithic tuffs of andesitic-dacitic composition, defined as Inesperada Hydro-magmatic Sequence. It covers a unit of green porphyric andesites with medium-sized plagioclase phenocrystals.
The gold grades observed varied mostly in a range between 0.5 gr/t and 3 gr/t Au, with a maximum gold grade of 19.17 gr/t Au. The Company assumes that the geological characteristics and orientation of the structural patterns observed in the veins will provide an important exploration guide to recognize the mineral potential of the Sierra Inesperada.

Forward Looking Statements
Statements in this news release that are not historical facts are forward-looking statements. Forwardlooking statements are statements that are not historical, and consist primarily of projections - statements regarding future plans, expectations and developments. Words such as 'expects', 'intends', 'plans', 'may', 'could', 'potential', 'should', 'anticipates', 'likely', 'believes' and words of similar import tend to identify forward-looking statements. Forward-looking statements in this news release include the Company's plan to review and analyze the results as it plans its next drill program, metallurgical testing, a geophysics campaign at Sierra Inesperada, and the Company's anticipation that the geological characteristics and orientation of the structural patterns will provide an important exploration guide to the geological potential at Sierra Inesperada.
All of these forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual events or results to differ from those expressed or implied, including, without limitation, business integration risks; uncertainty of production, development plans and cost estimates, commodity price fluctuations; political or economic instability and regulatory changes; currency fluctuations, the state of the capital markets, uncertainty in the measurement of mineral reserves and resource estimates, Austral's ability to attract and retain qualified personnel and management, potential labour unrest, reclamation and closure requirements for mineral properties; unpredictable risks and hazards related to the development and operation of a mine or mineral property that are beyond the Company's control, the availability of capital to fund all of the Company's projects and other risks and uncertainties identified under the heading 'Risk Factors' in the Company's continuous disclosure documents filed on the ASX and on SEDAR. You are cautioned that the foregoing list is not exhaustive of all factors and assumptions which may have been used. Austral cannot assure you that actual events, performance or results will be consistent with these forward-looking statements, and management's assumptions may prove to be incorrect. Austral's forward-looking statements reflect current expectations regarding future events and operating performance and speak only as of the date hereof and Austral does not assume any obligation to update forward-looking statements if circumstances or management's beliefs, expectations or opinions should change other than as required by applicable law. For the reasons set forth above, you should not place undue reliance on forward-looking statements.
