Exeter Reports: Drilling Commences at La Buena Project, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 17, 2013) - Exeter Resource Corp. (TSX:XRC)(NYSE MKT:XRA)(FRANKFURT:EXB) ("Exeter" or the "Company") is pleased to report that the first hole of the initial drill program at the La Buena project, Mexico, has commenced. This initial drill program is targeting the Julia zone at La Buena, which hosts a large scale geophysical target, elevated rock geochemistry and prospective geology.

The La Buena property, held under option from San Marco Resources Inc., consists of an 8,500 hectare land package located in an active mining region within northern Zacatecas State, Mexico. The property is 5 kilometres ("km") north of Goldcorp's La Negra/Noche Buena deposit and 9 km north of its Peñasquito mine. The Julia zone has similar geological, geochemical and geophysical characteristics to other mineral deposits in the area, including Peñasquito and Camino Rojo.

A recently completed property wide 3D IP geophysics program conducted by SJ Geophysics has reconfirmed that the Julia zone is host to the strongest near surface IP chargeability anomaly identified to date. The survey covered an area of over 35 square kilometres ("km²") on the La Buena property and outlined a series of potentially new areas of mineralization. The program successfully incorporated IP data from 2010 and 2011 with the new 3D IP data to develop a model that provides near surface resolution and additional information about the depth extent of the geophysical anomalies in the area. Work to date indicates that the Julia zone high chargeability anomaly is as close as 75 metres ("m") to surface and extends beyond 400 m vertically. The zone is also associated with a series of intersecting structures, and coincident elevated surface geochemistry (gold, silver, base metal).

Two areas at the Julia zone have been identified for initial drill testing. The first drill hole is designed to test a coincident chargeability high, low resistivity feature situated within the central region of a higher resistive zone rimming a topographical high feature. The second drill hole planned will target intersecting structural lineaments broadly associated with high chargeability zones. In addition, magnetic data reveals the presence of an elevated magnetic anomaly which appears to surround the central chargeability high. Furthermore, the region to the east of the Julia zone has been identified as having potential for additional drill targets.

The current 2,500 m drill program underway at La Buena is expected to be completed in Q4/13. Assay results are expected to be released following the completion of a series of drill holes. Exeter has the option to earn 60% in the La Buena property from San Marco and has committed to first year expenditures of C$1.4 million, which includes the now completed property scale IP geophysics program and the 2,500 m of drilling that is currently underway. San Marco is responsible for conducting exploration activities. For agreement details see Exeter's news release dated March 4, 2013.

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.
