Exeter Resource Corporation: Metallurgical Testing Yields Excellent Gold and Silver Recoveries for High-Grade Cerro Moro Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 1, 2007) - Exeter Resource Corporation (TSX VENTURE:XRC)(AMEX:XRA)(FRANKFURT:EXB) ("Exeter" or the "Company") reports that preliminary metallurgical testwork on a range of high-grade gold/silver mineralization from its Cero Morro project has yielded an average gold recovery of 94.8%.

Exeter contracted SGS Minerals Services in Santiago, Chile, to conduct the testwork using conventional processing on six samples taken from four prospects with head grades varying from 3 grams per tonne ("g/t") gold to 80 g/t gold. The gold recoveries, which were consistently high to very high, included samples with elevated base metals.

Silver recoveries were variable, but generally high. It is thought that the inclusion of a gravity recovery circuit ahead of leaching will improve the recovery of silver from higher grade samples. The addition of a flotation circuit will also be examined as an alternative mechanism for the recovery of silver and base metals.

Detailed Test Results

Because the preliminary metallurgical tests were carried out on samples that previously had been crushed and ground for assay purposes, the results are viewed primarily as a guide for planning detailed tests, which will start later this year. The simple bottle-roll leach tests were carried out on six ore-grade intercepts, ground to a nominal size of less than 100 microns, and leached for 72 hours.

The results are summarized in the following table:

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.

On October 30, 2007 the Company announced that it had acquired 100% of the Cerro Moro Project, one of 12 epithermal gold and silver properties that constitute a strategic agreement with CVSA. Drilling will continue through 2007-2008 at Cerro Moro where our focus is to establish a high grade gold-silver resource amenable to open pit mining.

In Chile, the Company is preparing for a major drilling program on the Caspiche gold porphyry project, located between the Refugio mine (Kinross Mining) and the giant Cerro Casale gold project (Barrick Gold and Kinross Mining). In southern Chile, Exeter is prospecting 48 gold, silver and base metal targets under a strategic agreement with Rio Tinto Mining and Exploration Limited.

As a result of recent political developments in Mendoza Province, Argentina, the further development of the advanced Don Sixto Gold Project has been put on hold. The Company recently filed suit in the Mendoza Courts challenging the constitutionality of the new legislation which has the effect of banning conventional mining in the province. The Company will, however, continue to work with authorities in Mendoza, and with representatives of other mining companies, to effect legislative amendment.
