Exeter Acquires Water Exploration Concession for the Caspiche Project, Chile

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 09/13/11 -- Exeter Resource Corporation (TSX: XRC) (NYSE Amex: XRA) (FRANKFURT: EXB) ('Exeter' or the 'Company') is pleased to report that the Chilean government has granted the Company a 10,726 hectare water exploration concession. The concession provides a second potential water source for the Caspiche gold-copper project. The concession is located approximately 100 kilometres (60 miles) north of Caspiche, at an elevation of 4,700 metres above sea level.

The aquifer is within the same high altitude region of the Andes where other mining companies hold granted water rights. The source of the water is seasonal snowmelt trapped by volcanic barriers and which is considered unlikely to make its way to the coastal plains. Water harvesting from such a basin would not be considered to have a negative impact on present and future supplies relied upon by coastal communities.

The Company expects to initiate a water exploration program comprising field mapping, geophysics, drilling and pump testing during Q4 2011, weather permitting.

Applications for two additional water exploration concessions in the area are still being processed by the relevant government authorities. Following approval, exploration programs will be extended to cover these concessions.

A mine at Caspiche is estimated to require less than 100 litres/second for the initial heap leach gold phase of the mine, rising to as much as 1,000 litres/second for a full scale sulfide mining operation.

In addition to the water exploration rights reported in this release, on February 8, 2011 (http://exeterresource.com/pdf/2011_news/Exeter_news_110208.pdf) Exeter reported an option over water rights of 300 litres/second from local owners. The seasonal thaw in October will allow us to continue with the baseline water flow program covering these water rights started earlier this year.

Exeter has retained specialist consultants to develop a water balance in the area with the objective of demonstrating that the use of these water rights for a mine at Caspiche will be sustainable over the project life. This will provide a technical basis for an application to the relevant authorities for permission to proceed with the installation of the necessary pumping and delivery infrastructure.

Exeter is continuing to study the availability of water in the region and to negotiate with other parties for the purchase or rental of water rights. The Company and its consultants are taking a constructive approach to Caspiche's water needs and the overall sustainability of the water resources needed by the mining industry.

In addition, the Company is pleased to report that the Pre-feasibility Study for the Caspiche Project, including in-pit crushing and conveying of waste rock remains on schedule for completion before the end of 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 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.
