Extorre Initiates Pre-Feasibility Study at Cerro Moro

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 8, 2010) - Extorre Gold Mines Limited (TSX:XG) (FRANKFURT:E1R) (OTCQX:EXGMF) ("Extorre" or the "Company") has engaged GR Engineering Services Pty Ltd ("GRES") of Perth, Australia, an internationally recognised engineering firm, to carry out the pre-feasibility study ("PFS") on its Cerro Moro gold-silver project in Santa Cruz Province, Argentina. The PFS is expected to be completed to a standard that will allow the Extorre board to make a development decision. 

The study will consider the development of an 8 year, 750 metric tons/day mine producing 133,500 ounces gold equivalent* annually for the first 5 years. The delivery date for the study is scheduled for Q2-2011.

GRES has excellent experience in feasibility studies, detailed engineering engagements and EPC / EPCM contracts on both small and medium scale precious and base metals projects. In 2008 GRES designed, constructed and commissioned the Higginsville Gold Mine in Western Australia, a very successful on time/on budget project for Avoca Resources.

Eric Roth, Extorre's CEO said, "GRES is well suited to perform the Cerro Moro PFS, and importantly has undertaken to complete the study within 6 months. The level of engineering requested by Extorre is to a level that will enable the project to proceed directly to a construction decision and detailed engineering. As Extorre has already submitted an Environmental Impact Assessment report to Provincial authorities, the Board is optimistic that a decision to proceed with commercial development could be made by June 30, 2011. 

"The commencement of the PFS process is clearly a milestone for Extorre. Importantly however, we will maintain an aggressive discovery drilling program through 2011 and 2012. This four rig program is designed to increase the resource base and to bring such new resources into the current mining plan or such expanded plan as results dictate."

The decision to proceed to the PFS stage follows the October 19, 2010 Preliminary Economic Assessment ("PEA") which indicated potential for a very low cost combined open pit/underground gold-silver mine. This PEA has now been filed on SEDAR and is publicly available for review. The PEA was based on the following main parameters:

About Extorre

Extorre is a Canadian public company listed on the Toronto Stock Exchange (symbol XG) and on the OTCQX (symbol EXGMF). Extorre's assets comprise approximately $47 million in cash, the Cerro Morro and Don Sixto projects, and other mineral 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.

* Gold equivalent grade / resource is calculated by dividing the silver assay/ resource 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.
