Extorre Announces High Grade Drilling Results at Cerro Moro Vancouver, B.C., March 5, 2012 – Extorre Gold Mines Limited (AMEX :XG,TSX:XG, Frankfurt: E1R, "Extorre" or the "Company") is pleased to announce high grade gold-silver assays from drilling at Cerro Moro, Santa Cruz Province, Argentina.

The assays relate to 83 drill holes, 36 from in-fill and step-out drilling at Zoe and 47 from testing other veins on the property. The Zoe vein drilling is part of a program to increase the density of drill holes within the known mineralized envelope. The results include high grade mineralization in many drill holes. Assay highlights from Zoe in-fill drilling include: MD1434A intersected 2.50 metres ("m") at 41.4 grams per tonne ("g /t") gold + 2,234 g/t silver (86.1 g/t gold equivalent*), including 0.35 m at 108.1 g/t gold and 5,812 g/t silver (224.3 g /t gold equivalent*). MD1447 intersected 3.72 m at 52.8 g/t gold + 4,299 g/t silver (138.7 g/t gold equivalent*), including 1.37 m at 131.4 g/t gold + 9,521 g/t silver (321.8 g/t gold equivalent*). MD1452 intersected 4.52 m at 8.2 g/t gold + 1,819 g/t silver (44 .6 g/t gold equivalent*), including 1.18 m at 27.9 g/t gold + 5 ,794 g/t silver (143.8 g/t gold equivalent*). MD1457 intersected 1.50 m at 50.7 g/t gold + 6,426 g/t silver (179 g/t gold equivalent*), including 0.54 m at 137 g/t gold + 17 ,419 g/t silver (485 g/t gold equivalent*). MD1498 intersected 1.80 m at 13.1 g/t gold + 1,111 g/t silver (35 .4 g/t gold equivalent*), including 0.50 m at 25.1 g/t gold and 1 ,641 g/t silver (57.9 g/t gold equivalent*). *Gold equivalent grade is calculated by dividing silver grades by 50 and adding this figure to the gold grade and assuming 100% metallurgical recovery. Two of the significant intercepts at Zoe (MD1452 and MD1457) are near surface, 60 and 40 metres respectively, vertically from surface. At Zoe, 15 of the 36 holes returned significant results and are presented in the table below, the remaining holes were narrow and/or low grade. Drilling on other Targets The 47 holes drilled towards the end of 2011 tested 19 other prospects at Cerro Moro, with over 10 of these prospects requiring additional follow-up.

A total of 17 holes returned significant results with the remaining holes returning low grade , no significant results or require additional drilling to determine the significance.

Exploration activities also continue to focus on the discovery of high grade gold-silver mineralization along interpreted eastward extensions to the Zoe mineralization.

A combination of detailed geological mapping, geochemistry and ground geophysics is being utilized to prioritize target areas for drill testing. Encouraging high grade gold-silver assays have been returned from new drilling on under-explored targets such as Mosquito, Tres Lomas and Belen.

At the Mosquito prospect, located 4 kilometres north of Escondida Far West, drill holes MD1392 (0.3 m at 8 g/t gold + 1,935 g/t silver (46.7 g/t gold equivalent*)) and MD1501 (0.7 m at 1.33 g/t gold + 1,270 g/t silver (26.7 g/t gold equivalent*)) have intersected very narrow but high grade mineralization.

Follow-up drilling on the structure is in progress, with the latest drill hole MD1542 having intersected visual silver and base metal mineralization (assays awaited). Overall the Mosquito vein structure is confirmed over 600 metres in strike length and remains open to the southeast.

Quality Control and Assurance 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.

Samples were prepared at the Acme Analytical Laboratories ("Acme Labs") preparation facility on-site at Cerro Moro (managed and staffed by Acme Labs), and assayed by fire assay (50 gram charge) at the Acme Labs laboratory in Chile, an ISO-9001:2000 certified laboratory.

Acme Labs is independent of Extorre. 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. 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 500 or 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, Extorres Exploration Manager and a "qualified person" (¨QP¨) 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 that forms the basis for this news release.

Drill core samples are collected under the supervision of Company geologists in accordance with standard industry practice.

The QP regularly audits this process during site visits.

In addition yearly or every two year audits by an independent QP are conducted, which includes the collection of additional samples that are analyzed at another laboratory to ensure Acme Labs laboratory performance meets required standards.

The QP receives the raw data results directly from the independent laboratory (as do the relevant Company geologists) and significant visual checks are performed to ensure there are no data entry issues in the main database. The QP personally verifies the results of the quality assurance and quality control samples (standards and blanks).

Core recovery is also checked and if below 90% for the reported mineralized intervals this is highlighted below the tables (however at Cerro Moro there appears to be no correlation between assay results or core recovery for the majority of intervals). The QP calculates all of the weighted grade average intervals using a 1.0 g/t gold equivalent* cut-off that are presented in the tables of significant results.

The QP also prepares and validates all of the figures presented in the release. About Extorre Extorre is a Canadian public company listed on the Toronto and NYSE Amex Exchanges (symbol XG).

The Company has scheduled the release of a Preliminary Economic Assessment before March 31, 2012.

That report is expected to include mineral resources on the Escondida-Zoe, Loma Escondida, Gabriela, Nini-Esperanza, Carla and Deborah mineralized zones.

It should be noted that a Preliminary Economic Assessment is by definition preliminary in nature as it includes some mineral resources that are too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as reserves at this time.

As such there is no certainty that a preliminary assessment and project economics will be realized. Four drill rigs are currently dedicated to both new resource and mine development-related drilling at the Cerro Moro Project.

The current program includes a combination of infill drilling at Zoe , wherein the primary goal is to convert high grade Inferred Category gold-silver resources to the higher confidence level Indicated Category Resources.

Discovery stage drilling is progressing on the Zoe East, Tres Lomas, Mosquito, Alejandra, and Carlita targets.

Limited mine-development related drilling, including water and geotechnical drilling is also in progress. Drill target generation activities continue on both the Cerro Moro property and the Companys other Santa Cruz Province regional tenement holdings. You are invited to visit the Extorre web site at

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 Commissions (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 Companys 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.
