Three drill rigs are currently dedicated to expanding the near-mine gold-silver resources at Cerro Moro. The Escondida vein in particular, has significant potential for expansion both along strike and at depth. In addition, other veins on the property with high gold-silver grades have only been partially evaluated to date. Outside of the Cerro Moro project area, Extorre will also initiate exploration to realize the discovery potential of other properties in its portfolio.

About Extorre

Extorre Gold Mines Limited is a Canadian public company listed on the Toronto Stock Exchange under the symbol "XG". It is a spin-out entity from Exeter Resource Corporation ("Exeter"). Extorre's assets comprise approximately $22 million in cash, the Cerro Morro and Don Sixto projects, and other exploration properties in Argentina.

On April 19, 2010, Extorre announced an updated National Instrument 43-101 compliant mineral resource estimate for Cerro Moro:

Indicated Category: 357,000 Oz. Gold + 15.3 Million Oz. Silver (612,000 Oz. Gold Equivalent*), plus

Inferred Category: 190,000 Oz. Gold + 12.0 Million Oz. Silver (390,000 Oz. Gold Equivalent*)

The 612,000 ounce gold equivalent* indicated resource, has an average grade of 32.3 g/t gold equivalent*, a grade considered exceptional by industry standards. The silver contribution is high, accounting for over 40% of the metal value. Additional inferred resources of 390,000 ounces gold equivalent* are also reported from Cerro Moro.

The updated resource model for the Escondida vein has been delivered to Extorre's consultants, Santiago-based NCL Ingenieria y Construccion, for mine design and ore scheduling. The results will be used in a Preliminary Economic Assessment (PEA) for the project which is scheduled to be complete in Q3-2010. The PEA will provide estimated mine operating and capital costs for a potential 100,000 ounce gold equivalent per annum mine. The submission of an Environmental Impact Assessment to Provincial authorities for permitting is also scheduled for Q3-2010.

Matthew Williams, Extorre's Exploration Manager considered a "qualified person" within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has supervised the preparation of the technical information contained in this news release.

* Gold equivalent grade is calculated by dividing the silver assay result by 60, adding it to the gold value and assuming
100% metallurgical recovery

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
