VANCOUVER, BRITISH COLUMBIA--(MARKET WIRE)--Jan 15, 2008 -- Exeter Resource Corporation (CDNX:XRC.V - News)(AMEX:XRA - News)(Frankfurt:EXB.F - News) ("Exeter" or the "Company") reports that diamond drilling at its Cerro Moro project in Santa Cruz Province, Argentina, has intersected bonanza gold and silver grades indicating an extension to the mineralized vein zone. The new drill holes, which are centred 500 metres (1,640 feet) northwest, and on strike of the previously defined Escondida zone, potentially extend the total mineralized zone to 1,500 metres (4,920 feet).
- 7.53 metres ("m") (24.7 feet) at 33.2 grams/tonne ("g/t") gold (0.96 oz/ton) and 2,219 g/t silver (54.94 oz/ton), a gold equivalent grade(i) of 70.21 g/t (2.05 oz/ton), from a down hole depth of 94.0 m (308.3 feet), including
- 2.76 m (9.05 feet) at 86.7 g/t gold (2.5 oz/ton) and 5,915 g/t silver (145.84 oz/ton), a gold equivalent grade(i) of 185.3 g/t (5.40 oz/ton), from a down hole depth of 97.87 m (321.0 feet) in hole MD216; and
- 3.42 m (11.2 feet) at 53.3 g/t gold (1.55 oz/ton) and 3,403 g/t silver (98.7 oz/ton), a gold equivalent grade(i) of 110.1 g/t (3.21 oz/ton), from a down hole depth of 152.4 m (500.0 feet) in hole MD218.
These holes were drilled below discovery drill hole MRC175, a reverse circulation percussion hole for which significant gold assay results were announced on November 26, 2007. Significant silver assays recently received, increased the gold equivalent grade by 44 percent, include:
- 6.0 m (19.7 feet) at 11.5 g/t gold (0.34 oz/ton) and 311 g/t silver (9.06 oz/ton), a gold equivalent grade(i) of 16.6 g/t gold (0.49 oz/ton) from a down hole depth of 68.0 m (223.1 feet), including
- 2.0 m (6.6 feet) at 31.1 g/t gold (0.91 oz/ton) and 746 g/t silver (21.76 oz/ton), a gold equivalent grade(i) of 43.5 g/t gold (1.27 oz/ton), from a down hole depth of 71.0 m (233.0 feet).
Diamond holes MD216 and MD218 are located on the same section line as MRC175, at vertical depths of approximately 70 m and 110 m respectively. A shallow drill hole, MD206, that tested the vein above (nearer surface) MRC175, intersected lower grades, including 2.8 m (9.2 feet) at 2.4 g/t gold (0.07 oz/ton) and 193 g/t silver (5.6 oz/ton), a gold equivalent grade(i) of 5.6 g/t (0.16 oz/ton) from a down hole depth of 38.45 m (111.5 feet).
Exeter's Chairman, Yale Simpson, commented: "The discovery of bonanza gold and silver grades on the strike extension of the known Escondida mineralization demonstrates the remarkable potential of the Cerro Moro veins. Again, the grade of mineralization is high, greatly enhanced by the silver content, and very importantly the widths of high grade mineralization are greater than in the zones previously drilled.
"The new discovery is concealed by thirty to forty metres of gravel and low grade mineralization, indicating that the mineralized body has not been eroded. Visual results, from exploratory drill holes along strike, indicate that the new high grade zone has a possible minimum strike length of 240 metres, with the zone remaining untested for some 400 metres to the southeast, before the previously announced western part of the Escondida zone is reached.
"Assays currently awaited are from a hole drilled beneath MD218, and two step-out drill holes 80 metres to the northwest. In addition, assays from two holes drilled to the southeast (along strike) are expected very shortly.
"Drilling to extend the Escondida vein system is continuing using one of the three rigs currently on the property."
Additional results from new diamond holes drilled on the western end of the main Escondida vein (located 400 m southeast of drill holes MD216 and MD218) include:
- 1.6 m (5.3 feet) at 6.5 g/t gold (0.19 oz/ton) and 620 g/t silver (18.08 oz/ton), a gold equivalent grade(i) of 16.9 g/t (0.49 oz/ton) from a down hole depth of 41.0 m (134.5 feet), including
- 0.4 m (1.3 feet) at 21.1 g/t gold (0.62 oz/ton) and 2,060 g/t silver (60.08 oz/ton), a gold equivalent grade(i) of 55.4 g/t (1.61 oz/ton), from a down hole depth of 42.2 m (138.5 feet) in hole MD149; and
- 2.4 m (7.87 feet) at 6.1 g/t gold (0.21 oz/ton) and 230 g/t silver (6.71 oz/ton), a gold equivalent grade(i) of 11.0 g/t (0.32 oz/ton), from a down hole depth of 34.9 m (114.5 feet) in hole MD169.
(i) Note: Gold equivalent grade is calculated by dividing the silver assay result by 60, adding it to the gold value and assuming 100% metallurgical recovery. Troy oz/ short ton calculated at grams per metric tonne divided by 34.2857 and rounded to 2 decimal places.

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 0.5 g/t gold cut-off grade, with no cutting of high grades. Reverse circulation drill samples are collected using a cyclone in one metre intervals; most samples are then composited into three metre samples. 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 ALS Chemex preparation facility in Mendoza and assayed by fire assay (50 gram charge) at the ALS Chemex 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 ALS Chemex. 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 reverse circulation 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 Cerro Moro Gold-Silver Project (100% owned by Exeter) in Santa Cruz Province, Argentina is generating high grade to 'bonanza grade' drilling results from an extensive epithermal vein system, located 130 kilometres (80 miles) east of the Cerro Vanguardia gold mine. Drilling will continue through 2008 using as a minimum three drill rigs. Our focus is to establish a high grade gold-silver resource amenable to open pit mining.
In Chile, the Company has started a major drilling program on its Caspiche gold porphyry project, located between the Refugio mine (Kinross Mining Corp.) and the giant Cerro Casale gold project (Barrick Gold Corp. and Kinross Mining Corp.).
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 has filed suit in the Mendoza Courts to challenge the constitutionality of new legislation, which has the effect of banning conventional mining in the province. The Company will continue to work with authorities in Mendoza, and with representatives of other mining companies, to effect legislative amendment.
In 2008, Exeter will drill other gold-silver targets in prospective regions of Patagonian Argentina and Chile. The Company gained a broad foothold in the region through separate strategic alliances with Cerro Vanguardia S.A. (an AngloGold Ashanti subsidiary), and Rio Tinto Mining and Exploration Chile.
