Vancouver, B. C., September 22, 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.

Results have been received from an additional 40 diamond drill holes from the Escondida West, Central, East and Fomicruz sectors. Of 23 drill holes returning significant results, 9 returned bonanza gold and silver grades (all from the West, Central and East sectors), as displayed in the following table.

Selected bonanza drilling results using a 1 gram per tonne ("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.

# Drill hole MD569 also intersected mineralization greater than 1.0 g/t gold equivalent from surface to 3.00 metres ("m") however the recoveries were significantly less than reporting requirements.

Of the 17 diamond drill holes with less significant results, 7 holes returned narrow and/or low grade intersections and 10 holes were poorly mineralized. The results from 6 holes at the Escondida Central and West sectors are awaited.

The locations of the 40 drill holes reported are represented on the following plans and long sections.

An additional 44 in-fill diamond drill holes have been drilled at the Escondida Far West sector. Results for the holes will be released following processing, sampling and assaying.

Drilling Progress on the Escondida Fomicruz Property
A reverse circulation percussion (RC) drill rig has completed an initial exploratory test of the potential northwest extension of the Escondida mineralized structure on the Escondida Fomicruz joint venture property. The rig firstly drilled through the blanket of Tertiary marine sediments before testing the underlying volcanic stratigraphy. Ten drill sections that included 11 RC holes and 2 diamond holes were drilled within a strike length of 1,600 m (160 m intervals).

The position of the Escondida structure was determined for each drill section, with assays now available for the first three holes. Drill hole MRC600, located 160 m northwest of the last mineralized Escondida Far West sector hole designated MD405 (1.62 m at a grade of 2.53 g/t gold and 100 g/t silver), returned 2.0 m at a grade of 1.8 g/t gold and 1.2 g/t silver, from a down hole depth of 141.0 m. Importantly, MRC600 was terminated at 146.0 m but was not sampled below 143 m due to poor sample recoveries.

On the next drill section, 160 m northwest of MRC600, drill hole MD587 was sited too far to the northeast to hit the Escondida structure. A follow-up hole, MD588, sited as a step back hole, successfully intercepted the target but failed to return significant mineralization.

Cerro Moro Project Manager, Fernando Chacon noted "Based on our experience to the southeast, subtle anomalous pathfinder element geochemistry in holes MD588 and MRC600 suggests these holes intersected the Escondida structure immediately above the precious metal precipitation zone of the epithermal system. The diamond drill is currently drilling 40 m spaced holes between MD405 and MRC600, with a series of deeper holes planned."

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 Acme Labs. 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.

On the Caspiche Project in Chile, Exeter recently announced an inferred mineral resource estimate of 1,117 Mt (million metric tons) at a grade of 0.55 grams per metric ton gold and 3.81 grams per metric ton silver including 1,017 Mt at a grade of 0.22% copper. This equates to in-situ inferred resources of 19.6 million ounces of gold, 137 million ounces of silver and 4.84 billion pounds of copper (a total of 33.7 million gold equivalent ounces**. Drilling to expand and upgrade the resource estimate is scheduled to commence in October 2009..

On the 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***. Exeter has drilled over 150 in-fill holes on the Escondida Vein structure to upgrade inferred resources to indicated resources for priority areas for a 2010 scoping study. Drilling will continue through 2009, as will engineering, environmental and infrastructure studies.

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.

**Gold ("Au") equivalence for copper ("Cu") and silver ("Ag") was calculated by Exeter using assumed metal prices of US$800/ounce ("oz") for Au, US$12/oz for Ag and US$2/pound ("lb") for Cu. The formula to calculate Au equivalence for Cu was pounds of Cu multiplied by 2 and divided by 800; Au equivalence for Ag was calculated using the formula oz of Ag multiplied by 12 and divided by 800, and in both cases assumes 100% recovery. Reported grades and metric tons have been rounded (see news release NR 9-19 dated September 14, 2009).

***Inferred mineral resource estimate of 1,098,000 tonnes 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 9-14 dated July 8, 2009).
