Vancouver, B.C., December 22nd, 2014 Exeter Resource Corporation (NYSE-MKT:XRA, TSX:XRC, Frankfurt:EXB – “Exeter” or the “Company”) is pleased to announce the expanded water drilling program (announced on October 7, 2014) for its Caspiche gold-copper project in northern Chile continues to provide encouraging results. Progress to date includes completion of two additional large diameter water bore holes (LV-05 and LV-06) and two smaller diameter water monitoring holes. As expected significant water (as determined by preliminary air lift tests) has been encountered in all drill holes. Down hole pump tests, a definitive measurement technique to quantify water flow rates and the recharge rate of an aquifer, have recently commenced. The Company expects to have pump tests completed on all remaining large diameter drill holes in January, 2015.

The water drilling program continues to support Exeter’s belief that the Peñas Blancas (option for 90% interest)¹ aquifer has the potential to provide sustainable water flows of over 200 litres per second (“L/s”). Such flow rates, if confirmed, should be adequate for any of the mining options outlined in its Amended NI 43-101 Technical Report on the Caspiche Project (“2014 PEA”). See the Exeter web site or Sedar for the details regarding the 2014 PEA.

The 2014 PEA identified three new low capex, potential development options, all of which required modest quantities of water compared with the requirements of a large scale open pit. The 2014 PEA calculated that the 30,000 tonne per day (“tpd”) standalone oxide operation would require a peak water supply of less than 50 L/s. This option produces an estimated average of 122,000 gold equivalent* ounces annually over a projected ten year mine life, including 148,000 ounces annually in the first five years.

The standalone oxide open pit mine plan benefits from lower up front capital requirements and sequenced higher start up grades in the initial part of the mine life. In addition, a very low life-of-mine strip ratio (0.27:1) and favorable leach kinetics are positive contributors to the project economics. At US$1,300/oz gold pre-tax net present value (“NPV”) is US$355 million, generating an internal rate of return (“IRR”) of 34.7%, and a payback period of 3.4 years from initial construction (after-tax 27% NPV 5% US$252 million, IRR 28.5%).

The other two potential development options considered the phased treatment of both oxides and sulphides at 60,000 tpd and 27,000 tpd respectively. One option looked at mining both gold in oxides and gold-copper in sulphides by open pit only. This option required a peak water supply of about 190 L/s. The other option looked at open pit mining of gold in oxides followed by selective high grade underground mining of gold-copper sulphide mineralization, an option that required a peak supply of 150 L/s.

Andinor Limitada, a specialist Chilean water drilling company, is the principal contractor for the water program. Supervision of the program by Exeter and JV personnel is augmented by expert, independent, external consultants. These consultants will also review and compile the water data which will form the basis of water applications to the Chilean water authorities.

Jerry Perkins, Exeter ́s VP Development and Operations and a “qualified person” (“QP”) within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has reviewed and approved the technical information in this news release.

The economic analysis contained in the PEA is considered preliminary in nature. No inferred mineral resources form part of the PEA studies and no mineral reserves for the PEA have been established. Mineral resources are not mineral reserves and have no demonstrated economic viability. There is no certainty that economic forecasts outlined in the PEA will be realized. The PEA and the April 2012 Mineral Resource (as defined) may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant factors.

¹ Exeter’s Chilean subsidiary, Minera Eton (“Eton”) and the Chilean subsidiary of Canadian company Atacama Pacific Gold Corporation (TSX-V : ATM) are jointly exploring for water in Northern Chile where Eton is earning an aggregate 90% interest in the Peñas Blancas concession and other water concessions. See Exeter news release NR 14-02 dated February 27th, 2014.

* Gold equivalent oz (AuEq) value is based on gold and silver revenues (prices and recoveries involved). AuEq oz [troy oz] = [Au g/t * Rec Au * tonnes]/31.1 + [Ag g/t * Rec Ag * tonnes]/31.1* silver price troy oz/ gold price troy oz. Recoveries are adjusted based on metallurgical characteristic of the resource.

About Exeter
Exeter Resource Corporation is a Canadian mineral exploration company focused on the exploration and development of the Caspiche project in Chile. The project is situated in the Maricunga gold district, between the Maricunga mine (Kinross Gold Corp.) and the Cerro Casale gold deposit (Barrick Gold Corp. and Kinross Gold Corp.). The discovery represents one of the largest mineral discoveries made in Chile in recent years. The 2014 PEA was initiated with the aim of indicating the development optionality of this world class discovery. The securing of water required for potential project development is a priority and exploration is ongoing.

The Company currently has cash reserves of C$31 million and no debt.

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. 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.
