VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 6, 2010) - Extorre Gold Mines Limited (TSX:XG) (FRANKFURT:E1R) (OTCQX:EXGMF) ("Extorre" or the "Company") is pleased to report assay results from the first six diamond drill holes completed on the new, silver rich, Lucia vein at Cerro Moro in Santa Cruz Province, Argentina. The vein is a new discovery located approximately 10 kilometres (6.2 miles) northeast of the high grade Escondida zone. The target structure at Lucia is over 2.5 kilometres (1.6 miles) long on the basis of geophysical (ground magnetic) data. At surface it consists of a poorly outcropping, quartz-adularia vein/stockworks zone that strikes northwest-southeast, a trend common to the majority of the high grade veins on the property.
The initial drill holes at Lucia were targeted on a 250 metre ("m'), (820 feet) long section of the vein, below a high grade surface outcrop. Highlights from two of the six diamond drill holes follow:
MD998 intersected 5.15m at 5.9 g/t gold + 1,083 g/t silver (23.9 g/t gold equivalent*)
MD1003 intersected 0.4m at 5.1 g/t gold + 1,247 g/t silver (25.9 g/t gold equivalent*)
Extorre´s Co-Chairman, Bryce Roxburgh stated, "The discovery of a second silver dominant vein in the northern sector of the Cerro Moro vein field (Gabriela was the first) has significant implications for the project. Historically, 40% of the project value lies with silver, yet with increasing silver prices and the identification of additional silver dominant veins, Cerro Moro has the potential to transition to a silver dominant deposit. The intersection of bonanza silver and gold values within the intercept quoted above for the first hole, MD998, of 0.45m at 51.8 g/t gold and 10,987 g/t silver (234.9 g/t gold equivalent*) clearly supports drill testing the entire length of the Lucia target to test for Escondida-style bonanza shoots. In a separate news release, we will provide an update on drill results from the other veins being drilled on the property."
The Lucia vein occupies an interpreted boundary fault that separates a block of volcanic rocks from a sedimentary sequence. Lucia appears to be a similar structure with a like geological setting to the Escondida vein, 10 kilometres (6.2 miles) to the southwest, which hosts 60% of the total currently reported Cerro Moro resource. Results presented also suggest that the Lucia mineralization may occur in irregular shaped shoots similar to those at Escondida.
Northwestern and southeastern extensions to the Lucia structural zone are clearly evident in our geophysical data. These extensions are currently being evaluated with widely spaced (160m (525 feet) apart) diamond drill holes over a 2.5 km (1.6 mile) distance.
Pre-feasibility study infill drilling, with the aim of converting existing Inferred resource category mineralization to higher confidence categories at both the Gabriela Central and Loma Escondida zones, is now essentially complete. The Company will now deploy three of the four diamond drill rigs currently on site to defining new gold and silver resources on the property. Priority targets for new resource drilling include the Lucia, Gabriela extensions, Esperanza, Carla and Martina zones. Extorre remains on track to release a new resource estimate in Q2-2011.
For consistency in reporting the Company will continue to report gold equivalent grades. The results below from the six holes at Lucia use a 1.0 g/t gold equivalent* cut-off grade:

Quality Control and Assurance
Drill widths presented above are drill intersection widths and may not represent the true widths of mineralization.
Gold assay results presented above are preliminary with no cutting of high grades. All diamond drill core samples are split on regular metre intervals or on geological contacts and represent sawn half HQ-size core. Reverse circulation drill samples are collected using a cyclone in one metre intervals. Samples were prepared at the Acme Analytical Laboratories ("AcmeLabs") preparation facility in Mendoza, Argentina and assayed by fire assay (50 gram charge) at the AcmeLabs laboratory in Chile, both ISO-9001:2000 certified laboratories.
Check assaying of all samples assaying greater than 1.0 g/t gold is completed by Acme Labs. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses. Standard and blank samples are used throughout the sample sequence as checks for the diamond drilling reported in this release. Standard, blank and duplicate samples are used throughout the sample sequence as checks for RC percussion drilling.
Assaying by the screen fire assay method has been implemented in conjunction with standard 50 gram fire assaying, for diamond drill cores that contain visible gold. The procedure for screen fire assaying involves crushing and sieving of a nominal 1,000 gram sample to a particle size of 100 microns. All material which does not pass through the 100 micron sieve is then assayed. Two fire assays are undertaken on the undersize material as a check on homogeneity. The total gold content is then calculated.
Matthew Williams, Extorre's Exploration Manager and 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.
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 $47 million in cash, the Cerro Morro and Don Sixto projects, and other mineral exploration properties in Argentina.
On April 19, 2010, Extorre announced an updated National Instrument 43-101 compliant mineral resource estimate for Cerro Moro:
Indicated Category: 357,000 oz. gold + 15.3 million oz. silver (612,000 oz. gold equivalent*), plus
Inferred Category: 190,000 oz. gold + 12.0 million oz. silver (390,000 oz. gold equivalent*)
The 612,000 ounce gold equivalent* indicated resource, has an average grade of 32.3 g/t gold equivalent*, a grade considered exceptional by industry standards. The silver contribution is high, accounting for over 40% of the metal value. Additional inferred resources of 390,000 ounces gold equivalent* are also reported from Cerro Moro.
Extorre released the results of a Preliminary Economic Assessment (PEA) of the Cerro Moro Project on October 19, 2010. The PEA highlighted the robust economics of the future Cerro Moro mine, in which an average of 133,500 gold equivalent* ounces would be produced during the first 5 years of operation at a cash cost of US$ 201 per ounce (net of silver credits). Project CAPEX has been estimated at US$ 131 million (of which 21% is tax that is refundable after production commences), with a payback period of 1.8 years. The project economics were calculated using gold and silver prices of US$ 950/ounce and US$ 16/ounce, respectively.
Extorre also submitted its Environmental Impact Assessment for the Cerro Moro mine development to Santa Cruz Authorities on September 16, 2010. Mining permits and approvals for the Cerro Moro mine are expected to be received by the end of Q1-2011.

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.
