Extorre Comments on YPF Developments in Argentina

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 19, 2012) - Extorre Gold Mines Limited (TSX:XG.TO) (NYSE Amex:XG) (FRANKFURT:E1R.F) ("Extorre" or the "Company) wishes to provide its insight on the proposed acquisition by the Argentine Federal Government of 51% of the Argentine oil company, Yacimientos Petroliferos Fiscales (YPF), from Spanish Oil Company Repsol.

It is important to note that there are significant differences in regulations, tradition, public importance and internal use of products between the oil & gas sector and the mining industry in Argentina. Public policy in one sector is not connected with the other.

Furthermore, the Argentinean Government initiative currently under discussion before Congress has been enacted only in connection with YPF which has a long Argentinean history. Extorre notes that YPF was State owned from its inception in the early 1920's until the late 1990's, when it was privatized and a majority stake sold to Repsol. The current re-nationalization process of YPF has not been extended to other oil & gas companies operating in Argentina.

There is no reported agenda in the popular press or, to Extorre's knowledge, to extend the nationalization process to any other company in the oil and gas sector in Argentina or to any other sector of the economy. Additionally, recently, several mining Provinces have joined an alliance in support of mining with the acknowledgment of the Argentinean Government and none of the objectives of that alliance relate to any action or policy similar to the one taken in connection with YPF. The mining sector has also received explicit public support from the Provinces and the Federal Government.

Several other mining companies operating in Argentina have publicly commented on this situation in terms similar to Extorre's view.

Very recent discussions with potential financiers to provide capital for the potential development of Cerro Moro have indicated that the YPF action has not materially affected the finance ability of the project.

About Extorre

Extorre is a Canadian public company listed on the Toronto and NYSE Amex Exchanges (symbol XG). The principal assets of the Company comprise CDN $35 million in cash and the Cerro Moro, Puntudo and Don Sixto projects in Argentina.

On April 2, 2012 Extorre announced the results of a Preliminary Economic Assessment ("PEA-3") for a potential mine development at Cerro Moro. The study was based on the November 2011, NI 43-101 mineral resource estimate. That study modelled a nine year mine to produce 850,000 ounces gold and 47 million ounces silver. The proposed mine would produce an average of 248,000 ounces gold equivalent(i) per year for the first 5 years at a cash cost of US $303/ounce gold equivalent(i).

Exploration with four drills continues at Cerro Moro, a program designed to increase the total resources on the property and to in-fill drill certain areas for mine planning purposes. Results from current drilling will be released when available.

It should be noted that PEA-3 is preliminary in nature as it includes inferred mineral resources which are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that PEA-3 will be realized.

(i)Gold equivalent ounces are calculated by dividing the silver ounces by 50 and adding it to the gold value.

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.

NEITHER THE TSX NOR ITS REGULATION SERVICES PROVIDER (AS THAT TERM IS DEFINED IN THE POLICIES OF THE TSX EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS NEWS RELEASE
