Vancouver, B. C., July 29, 2009 - Exeter Resource Corporation (AMEX:XRA, TSX-V:XRC, Frankfurt: EXB - "Exeter" or the "Company") is pleased to report on progress from its in-fill drilling program on the high grade Escondida vein at Cerro Moro in Santa Cruz Province, Argentina.

Assays from a batch of 14 diamond drill holes on the Escondida vein include bonanza grades in drill holes MD475 and MD479, two holes that represent extensions to reported high grade mineralization in the Escondida Far West sector. This portion of the Escondida vein accounts for approximately 40% of the currently defined Escondida Zone resource.

Detailed drilling results using a 1 g/t gold equivalent* cut-off grade:

* Gold equivalent grade is calculated by dividing the silver assay result by 70, adding it to the gold value and assuming 100% metallurgical recovery.

Exeter recently announced an initial inferred mineral resource estimate of 646,000 ounces gold equivalent** at a grade of 18 grams per tonne ("g/t") (0.52 ounces per ton ("oz/ton") gold equivalent**. The current focus is to advance drilling on the Escondida vein zone, which contains 519,000 ounces gold equivalent** at a grade of 34 g/t (1.0 oz/ton) gold equivalent**. In particular, the Company expects that the program will generate the data necessary to upgrade the recently announced "inferred resource" to an "indicated resource" by Q1, 2010. This is an essential step towards completing a scoping study for developing a high grade mining operation on the property.

In the Far West sector of the Escondida vein, the Company has drilled a total of 24 diamond core holes to confirm the exceptional grades previously announced in that sector. Of the 14 drill holes announced in this news release, 13 are from that sector and are represented on the following longitudinal drill section.

Drill hole MD467, on the West sector, successfully intersected high grade mineralization 140 metres ("m") (459 ft) vertically below surface, thereby demonstrating the potential for deeper high grades in that area.

Results are awaited from infill drilling on the West, Central and East sectors of the Escondida vein, where an additional 95 diamond drill holes for approximately 4,800 m (15,744 ft) are being logged and assayed. The majority of these holes are shallow and represent an approximate 20 x 20 m (65 x 65 ft) "staggered" pattern to assist with preliminary mine scoping models. Significant results will be released during August and September as the assays are collated and verified.

Progress on the Escondida Fomicruz Property
Due to a delay in the arrival of a reverse circulation percussion (RC) rig the Company used the available diamond rig to conduct a 300 m (984 ft) program to confirm that the prospective Escondida structure extends onto the Fomicruz joint venture property. The rig was sited well into the Fomicruz lands, some 320 m (1,050 ft) northwest of the last hole drilled by Exeter at Escondida Far West. The Escondida structure was successfully located under 40 m of gravel cover, confirming our geophysical interpretation that the Escondida structure has an untested strike length of some 2.3 kilometres (1.43 miles) on the Fomicruz property (a distance similar to that drill tested to date at Escondida).

The Company has contracted a RC drill rig to drill a minimum of 15 holes (2,000 m (6,560 ft) program) on the Fomicruz lands. This program is scheduled to commence early next month with initial results to follow in September.

Quality Control and Assurance
Drill widths presented above are drill intersection widths and may not represent the true widths of mineralization.

Gold assay results presented above are preliminary and have been calculated using a 1.0 g/t gold equivalent cut-off grade*, with no cutting of high grades. All diamond drill core samples are split on regular metre intervals or on geological contacts and represent sawn half HQ-size core. Samples were prepared at the Acme Analytical Laboratories ("AcmeLabs") preparation facility in Mendoza, Argentina and assayed by fire assay (50 gram charge) at the AcmeLabs laboratory in Chile, both ISO-9001:2000 certified laboratories.

Check assaying of all samples assaying greater than 1.0 g/t gold is completed by AcmeLabs. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses. Standard and blank samples are used throughout the sample sequence as checks for the diamond drilling reported in this release. Standard, blank and duplicate samples are used throughout the sample sequence as checks for the RC percussion drilling.

Assaying by the screen fire assay method has been implemented in conjunction with standard 50 gram fire assaying, for diamond drill cores that contain visible gold. The procedure for screen fire assaying involves crushing and sieving of a nominal 1,000 gram sample to a particle size of 100 microns. All material which does not pass through the 100 micron sieve is then assayed. Two fire assays are undertaken on the undersize material as a check on homogeneity. The total gold content is then calculated..

About Exeter
Exeter Resource Corporation is a Canadian mineral exploration company focused on the discovery and development of gold and silver properties in South America. The Company has C$30 million in its treasury.

The Caspiche gold-copper discovery*** is situated in the Maricunga gold district of Chile, between the Refugio mine (Kinross Gold Corp.) and the giant Cerro Casale gold deposit (Barrick Gold Corp.. and Kinross Gold Corp.). Over 16,500 m were drilled during the 2008/2009 drill season. The program focussed on delineating the external boundaries of Caspiche. A second National Instrument 43-101 compliant resource estimate, which incorporates the results from drilling completed subsequent to December 31, 2008, is expected to be available in September 2009.

On its Cerro Moro Project in Argentina, Exeter recently announced an initial inferred mineral resource estimate of 646,000 ounces gold equivalent** at a grade of 18 g/t gold equivalent**. To date, Exeter has drilled over 100 infill holes on the Escondida vein structure in order to upgrade the sectors of the inferred resource that might be scheduled for early mining. Drilling will continue through 2009. Plans include drilling of a possible extension of the Escondida zone on the adjacent Fomicruz joint venture property. Engineering, environmental and infrastructure studies are being advanced ahead of a scoping study in 2010.

No site work is planned on the Don Sixto gold-silver project in Argentina over the next quarter. The Company will continue to work with provincial authorities and with representatives of other mining companies, to effect amendment to the 2007 legislation that banned the use of cyanide in mining operations in Mendoza Province.

** Inferred mineral resource estimate of 1,098,000 metric tons containing 371,000 ounces gold at a grade of 10.5 g/t and 19.2 million ounces silver at a grade of 545 g/t for 646,000 ounces gold equivalent at a grade of 18 g/t gold equivalent. Gold equivalent is calculated by dividing the silver assay result by 70, adding it to the gold value and assuming 100% metallurgical recovery (see news release NR 09-14 dated July 8, 2009).
*** Inferred mineral resource estimate of 449.9 million tonnes from the oxide and gold-copper zone contains 8.7 million ounces gold at a grade of 0.6 g/t and 375.9 million tonnes from the gold-copper zone only contains 2 billion pounds of copper at a grade of 0.25% (see news release NR 09-09 dated March 24, 2009).
