Exeter Reports Progress on Development Studies at the Caspiche Gold-Copper Project, Chile

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/26/11 -- Exeter Resource Corporation (NYSE Amex: XRA)(TSX: XRC)(FRANKFURT: EXB) ('Exeter' or the 'Company') is pleased to provide a progress update on the pre-feasibility study (PFS) for its Caspiche gold-copper project in the Maricunga district, Chile.

In November, 2010 Exeter announced the appointment of Jacobs Engineering (formerly Aker Solutions) of Santiago, Chile to carry out a PFS for its Caspiche gold-copper project. The study is currently scheduled for delivery in late Q4-2011.

The study considers a number of mining and mineral processing options and treatment throughputs designed to maximize the project's profitability.

Mining alternatives include both a large open pit (Super Pit) mining operation considering a production rate on sulphide ore of 150,000 tonnes/day (approximately 54Mtpa) and a hybrid mining scenario at a production rate of 95,000 tonnes/day. The latter envisages a moderate size open pit in the first phase of the mine life, to generate early cash flow, before transitioning to an underground block cave operation to extract the higher grade ore located at depth within the deposit.

In both cases the production of heap leachable oxide ore at surface would be fast tracked to provide near term cashflow during construction of the larger project and will continue in parallel with sulphide production until this shallower material is exhausted.

In parallel to the advancement of these scenarios, a number of new initiatives have been implemented with potential to positively impact project economics. These initiatives, which include inpit crushing and conveying (IPCC) and converting some of the lower grade mineralization from 'waste' into 'ore' by enhancing recoveries through ongoing detailed metallurgical testwork, are not expected to significantly affect the report delivery date.

Jerry Perkins, Exeter's VP Development and Operations stated 'internal scoping level studies on IPCC of waste demonstrated that this would significantly reduce the mine operating costs and provide a useful buffer against potential rises in fuel prices. In addition, downhill waste conveying is expected to generate sufficient power to cover the crushing and conveying requirements. Following earlier work on the conventional trucking option, it was decided that IPCC studies would be advanced as an integral component of our PFS.

'Inpit crushing is commonly used in iron ore, bauxite and coal mining, but more recently it is being implemented for metal mining. Sandvik Mining and Construction, which has been contracted for the IPCC component of our PFS, has been responsible for the implementation and successful operation of IPCC for the Mae Moh coal mine in Thailand since 2002, and the Boliden Atik copper mine in Sweden. We are fortunate that technology has advanced beyond conventional trucking of material to allow IPCC, as the large pit at Caspiche is potentially 1 kilometre deep and 2 kilometres across, requiring considerable trucking time to dump waste rock from lower pit levels.

'Our corporate goal continues to be to enhance project value through ongoing assessment and evaluation of the PFS as they progress in order to maximize shareholder value.'

Jerry Perkins, Exeter's VP Development and Operations 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.

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.
