– May 23, 2013: Exeter Resource Corporation (NYSE-MKT:XRA, TSX:XRC, Frankfurt: EXB – "Exeter" or the "Company") is pleased to announce that the initial results from the first 7 drill holes at the Angeles property in northern Sonora state, Mexico have intersected significant gold, silver, copper, lead and zinc mineralization.

Drilling has initially targeted the La Bonanza area, a site of historical mining at the turn of the 1900s.

Importantly, the current drilling program is the first ever to test the Angeles property. Drilling has tested 100 metres of a possible 3,000 metre strike length of identified surface mineralization at Angeles.

All drill holes to date have intersected the Angeles structure, the main target of historical mining.

Drill holes AD13-03 and AD13-07 are the deepest down dip intersections below surface (about 160 metres), and exhibit the highest gold, silver and base metal grades encountered to date. Exeters Co-Chairman, Bryce Roxburgh, stated "initial drill results at the Bonanza zone confirm our initial interpretation that the Angeles project has the potential to host significant gold, silver and base metal mineralization.

Over the past 12 months Exeter has reviewed a significant number of projects and selected this unique property, which has been overlooked for a century". Highlights of assays from AD13-03 and AD13-07 include the following: Hole AD13-07 – Section C FromToInterval (metres)Au g/tAg g/tAu Eq¹ g/tCu%Pb %Zn %% Pb-Zn Combined 166.15169.703.553.9362.75.180.741.220.631.84 Including: 166.15168.652.505.5085.87.211.041.680.872.55 167.05168.651.608.17120.210.581.572.580.883.46 Hole AD13-03 – Section A FromToInterval (metres)Au g/tAg g/tAu Eq¹ g/tCu%Pb %Zn %% Pb-Zn Combined 146.00152.206.202.81644.090.551.160.902.06 Including: 147.00152.205.203.33724.770.651.360.952.31 147.00148.151.157.3814110.200.642.501.924.42 Corresponding long section and drill cross sections are as follows: View the higher resolution version of the corresponding long section and drill cross sections.

Plan Map & Long Section: Cross Section A: Cross Section B: Cross Section C: The current program is about 60% through the first year budget of $1 million.

Subsequent to completing the above drilling, the drill rig moved 1.1 kilometre to the west (along the same Angeles structure), where 4 holes were recently completed.

Additional drilling is scheduled at the Bonanza zone to test on the strike extension of mineralization, and the trend of higher grade mineralization with increasing depth. Exeter is currently funding a CAD$1.0 million committed exploration program at Angeles, which is largely related to a planned 2,500 metres of drilling at the Bonanza and La Verde target areas, pursuant to an agreement whereby it can earn up to 70% in the Angeles property.

For agreement details see Exeters news release dated March 4, 2013.

Metallurgical recoveries and net smelter returns are assumed to be 100% for these calculations.

Drill intervals reported are down hole intercepts.

True widths are yet to be determined but are interpreted to range between 75-100%.

San Marco Resources is the project operator until Exeter earns an initial 51% interest.

Copper, lead and zinc values are not included in Au Eq calculations.

Drill core recovery of the announced mineralized zones is generally greater than 90%, unless otherwise noted.

Drilling is proceeding with HQ drill core unless otherwise noted.

Assay intervals were selected using visuals of geology and mineralization.

No cut-off grade was used. Quality Control and Assurance Blanks and certified standards were inserted into the sample stream as part of San Marcos quality assurance and control program, which complies with National Instrument 43-101 requirements.

The analyzes reported were carried out at ALS Chemex Laboratories located in North Vancouver, B.C., using industry standard analytical techniques.

For gold, samples are first analyzed by fire assay and atomic absorption spectroscopy ("AAS").

Samples that return values greater than 10 g/t gold using this technique are then re-analyzed by fire assay but with a gravimetric finish.

Silver is first analyzed by Inductively Coupled Plasma - Atomic Emission Spectroscopy ("ICP-AES").

Samples that return values greater than 100 g/t silver by ICP-AES are then re analyzed by HF-HNO3-HCLO4 digestion with HCL leach and ICP-AES finish.

Geol, a qualified person for the purpose of National Instrument 43-101, Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators. About Exeter Exeter is a Canadian mineral exploration and development company.

Its principal focus is the advancement of its 100% owned Caspiche gold-copper project in Chile.

Caspiche is one of the largest undeveloped gold-copper deposits in the Americas and is situated in the Maricunga gold district, between the Maricunga mine (Kinross Gold Corp.) and the Cerro Casale gold-copper deposit (Barrick Gold Corp.

and Kinross Gold Corp.).

The Company continues to evaluate new opportunities related to the advancement of Caspiche, and new industry wide opportunities with the objective of securing properties, which offer near term discovery potential. Exeter has completed pre-feasibility studies that demonstrate the potential for commercializing Caspiche.

The Company currently has cash reserves of CAD$47 million and no debt. You are invited to visit the Exeter web site at www.exeterresource.com EXETER RESOURCE CORPORATION Wendell Zerb, P.

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 U.S.

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.
