+100 drill holes completed on multiple mineralized zones
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 06/21/10 -- Extorre Gold Mines Limited (TSX: XG) (FRANKFURT: E1R) (PINK SHEETS: EXGMF) ('Extorre' or the 'Company') reports that 4 drill rigs are testing new veins and/or new drill targets, as part of a program designed to meet our goal of expanding the Cerro Moro resources to 2 million ounces. Over 100 new drill holes have been drilled since the April 19, 2010 Resource Statement.
A significant assay backlog is currently affecting progress, with some 4,000 sample results awaited. Extorre will now build a dedicated on-site sample preparation facility, to be managed by an independent, accredited geochemical contractor. This is expected to significantly shorten assay turnaround times.
Fortunately many of the new exploration holes are able to be targeted and drilled on the basis of geological logging of drill core, utilizing quartz vein textures and the presence of the silver sulphide mineral acanthite as vectors to ore grade mineralization. Acanthite is clearly evident in other veins at Cerro Moro and its presence justifies drilling of targets, ahead of confirmatory assays.
The following new zones are being tested:
-- A southeastern extension of Escondida mineralization, Escondida Far
Southeast, appears to be hosted within an extensional 'jog' along the
main Escondida structure. Two rigs are drill testing a one kilometre
long target.
-- A 3rd rig is currently drilling a southeastern extension to the Gabriela
vein. The previously drilled northwestern part of the vein was reported
as an 'inferred resource' in the April resource statement. To date the
new zone has been traced by drilling over a strike length of 350 metres.
The Gabriela target remains open both along strike and down-dip.
-- A new vein, referred to as the Carolene vein, has been drill tested over
650 metres of strike length on the basis of visible encouragement. The
Carolene vein is located on the northern margin of the Escondida horst
block, in a comparable geological setting to the Escondida vein
structure. The Carolene structure is regarded to be a key exploration
target.
-- The previously known Carla vein has also been further drilled, as the
target is known to be high grade and shallow, thus amenable to providing
additional resources to Cerro Moro. Additional drilling is planned.
It is proposed that drilling with multiple rigs will be maintained for the foreseeable future through the mine permitting and development period for Cerro Moro. Drill hole assay intercepts will be reported as soon as sufficient assays are accumulated to report the potential of new discoveries and their potential impact on the project economics.
Exploration on other projects in Santa Cruz is now sufficiently advanced to enable drill testing. The first prospect to be tested is referred to as the Falcon Project, an undrilled gold target known previously as Calandria. Results should be reportable in Q3-2010.

About Extorre
Extorre is a Canadian public company listed on the Toronto Stock Exchange under the symbol 'XG'. It is the spin-out entity from Exeter Resource Corporation ('XRC' on the TSX and 'XRA' on the NYSE-Amex). Extorre's assets comprise approximately $20 million in cash, the Cerro Morro and Don Sixto projects and several other exploration properties in Santa Cruz.
On April 19, 2010, Extorre announced an updated National Instrument 43-101 compliant mineral resource estimate for Cerro Moro: Indicated Category(ii): 357,000 Oz. Gold + 15.3 Million Oz. Silver (612,000 Oz. Gold Equivalent(i)), plus Inferred Category(iii): 190,000 Oz. Gold + 12.0 Million Oz. Silver (390,000 Oz. Gold Equivalent(i))
The 612,000 ounce gold equivalent(i) indicated resource, has an average grade of 32.3 g/t gold equivalent(i), 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(i) 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.

(i)Gold equivalent grade is calculated by dividing the silver assay result by 60, adding it to the gold value and assuming 100% recovery.
(ii) Based on 590,000 tonnes at 18.9 g/t gold and 805 g/t silver, for a gold equivalent grade of 32.3 g/t.
(iii) Based on 1,970,000 tonnes at 3.0 g/t gold and 190 g/t silver, for a gold equivalent grade of 6.1 g/t.

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 U.S., 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.
