About Extorre

Extorre is a Canadian public company listed on the Toronto and NYSE Amex Exchanges (symbol XG). The assets of the Company comprise CDN $27 million in cash, the Cerro Moro, Puntudo and Don Sixto projects, and other mineral exploration properties in Argentina.

On August 4, 2011 Extorre announced the results of the second Preliminary Economic Assessment ("PEA-2") for a potential mine development at Cerro Moro. The study was based on the interim (April, 2011) NI 43-101 compliant mineral resource estimate which did not include any resources from the Zoe discovery, as it was still being drilled at that time. In PEA-2 production was based on an 8.25 year, 1,000 tonnes per day mining and processing operation producing a total of 494,700 ounces of gold and 26.6 million ounces of silver. The proposed mine would produce an average of 206,300 ounces gold equivalent* per year for the first 3 years at a cash cost of US $236/ounce gold equivalent*.

* Gold equivalent ounces are calculated by dividing silver ounces by 50 and adding this figure to gold ounces.

Cautionary Note to United States Investors - The information contained herein and incorporated by reference herein has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. In particular, the term "resource" does not equate to the term "reserve". The Securities Exchange Commission's (the "SEC") disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by SEC standards, unless such information is required to be disclosed by the law of the Company's jurisdiction of incorporation or of a jurisdiction in which its securities are traded. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.
