Exeter Drilling Discovers Gold-Silver Mineralization at Caspiche, Chile

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 2, 2007) - Exeter Resource Corporation (TSX VENTURE:XRC)(AMEX:XRA)(FRANKFURT:EXB) (the "Company") reports that initial drilling at its Caspiche epithermal gold property in Chile, has encountered significant gold and silver mineralization.

Six reverse circulation drill holes were drilled for a total of 1,667 metres. Highlight results, in grams per tonne ("g/t"), include:

- 24 metres at a grade of 1.1 g/t gold and 23 g/t silver from a down hole depth of 52 metres in hole CSDH 002
(79 feet at a grade of 0.032 oz./ton gold and 0.66 oz./ton silver from 171 ft)

- 6 metres at a grade of 1.7 g/t gold and 16 g/t silver from a down hole depth of 172 metres in hole CSDH 002
(20 feet at a grade of 0.049 oz./ton gold and 0.46 oz./ton silver from 564 ft)

- 22 metres at a grade of 1.5 g/t gold and 1.6 g/t silver from a down hole depth of 144 metres in hole CSDH 006
(72 feet at a grade of 0.435 oz./ton gold and 0.046 oz./ton silver from 472 ft)

The drilling has confirmed the presence of a high-sulphidation epithermal gold system on the northern flank of the Caspiche Porphyry. The mineralization is interpreted to lie within flat lying replacement zones that are related to a gold-copper bearing intrusive body.

Jason Beckton, Exeter's Manager in Chile, stated, "Our discovery represents a different type of deposit from the Caspiche copper-gold porphyry system previously discovered in the area by Minera Anglo American Chile Limitada and Empresa Minera Mantos Blancos S.A. ("Anglo American"). Importantly the grade of the mineralization discovered is significantly higher than the average grade of the Caspiche Porphyry and the nearby Refugio and Cerro Casale gold-copper deposits.

In the case of drill hole CSDH 002, the gold-silver mineralization is within a stratabound zone at least 24 metres thick, situated at the top of the Rio Nevada volcanic sequence, directly beneath the footwall contact of the overlying Yeguas Heladas conglomerate and felsic tuff formation. This has significant implications for the discovery of widespread mineralization, particularly given that outcrop is only 3 percent.

CSAMT and VLF electromagnetic geophysical programs conducted on the property by Exeter in late 2006 had indicated the presence of resistive anomalies interpreted to be potentially mineralized silica bodies extending for five kilometres. The surveys also indicated that the zone is quite separate from the Anglo American copper-gold discovery.

Identifying targets to drill using geophysical methods is generally an "inexact" positioning method, hence several drill holes missed the interpreted silica bodies. Further drilling will better define the geometry and extent of the new mineralization."

Note: Significant drilling results are those that have a greater than 0.5
g/t gold equivalent grade.
Gold assays are by the fire assay method and silver analyzed by ICP.
The minimum sample intercept length is 2 metres.
All significant results from the drill program are reported above.

The strike length of the target zone is 5 kilometres, of which only approximately 700 metres was tested in this drill program. The next phase of drilling will be extended to test a strike length of approximately 1.5 kilometres target zone. Drill hole CSDH 001 collapsed before reaching target depth and was replaced by drill hole CSDH 001A. Drill holes CSDH 001A, 003 and 004 did not effectively test the target zone. Drill hole CSDH 005 is interpreted to have drilled a quartz biotite porphyry intrusive body which may relate to fluid feeders for the overlying epithermal system.

Quality Control and Assurance

The gold and silver assay results presented above are preliminary and have been calculated using a 0.5 g/t gold equivalent cut-off grade, with no cutting of high grades. All reverse circulation drill samples are collected using a cyclone in two metre intervals; no compositing is undertaken at the rig. Gold samples were prepared and assayed by fire assay (50 gram charge) and ICP-MS used for silver at the ACME laboratory in Santiago, an ISO-9001:2000 certified laboratory.

Standard, blank and duplicate samples are used throughout the sample sequence as checks for the exploratory reverse circulation drilling. Drill widths presented above are drill intersection widths and may not represent the true widths of mineralization.

About Exeter

Exeter is a Canadian mineral exploration company focused on the discovery and development of epithermal gold-silver properties in South America.

In Mendoza Province, Argentina, the La Cabeza Project is advancing rapidly to a decision on mine development options. A multi-rig drilling program was completed in December and core logging, sampling and assaying is nearing completion. A new, independent resource calculation is scheduled for release in May, ahead of a scoping study to establish the parameters of further feasibility and environmental studies. News releases over the coming weeks will update drilling results as they become available.

In the prospective, Patagonia region of Argentina, Exeter is currently drilling the Cerro Moro epithermal gold property, one of 12 gold and silver properties that constitute a strategic agreement with Cerro Vanguardia S.A., an AngloGold Ashanti subsidiary. Results are expected to be available in early March.

In southern Chile, Exeter is prospecting 48 gold, silver and copper targets under a strategic agreement with Rio Tinto Mining and Exploration Limited.
