Exeter Resource Corporation: Caspiche Drilling Indicates Extent of Gold-Copper Porphyry System

VANCOUVER, BRITISH COLUMBIA -- 06/23/08 Exeter Resource Corporation (TSX VENTURE: XRC)(AMEX: XRA)(FRANKFURT: EXB) ("Exeter" or the "Company") is pleased to report that results from recent drilling at Caspiche, Chile, indicate that the target deposit has a minimum footprint of some 600 metres (1,968 feet) by 500 metres (1,640 feet), and remains open for extension to the east, west, south and to depth.

The onset of winter conditions forced the suspension of two key "scissor" diamond drill holes, CSDH-025 and CSD-H026. CSDH-025, located 100 metres ("m") (328 feet ("ft")) north of hole CSD-016 and 100m (328 ft) south of hole CSD-015, returned excellent grades down to 336.05m (1,102 ft), the depth at which the hole was suspended. CSDH-025 will be completed to a minimum depth of 750m (2,460 ft) in October when drilling resumes on the project. Drill hole CSD-026 was suspended in the lithocap at 208.95m (685 ft) and will also be extended.

Results for drill hole CSDH-025 are as follows:

- 292.05m (958 ft) at a grade of 0.86 grams per tonne ("g/t") (0.025 ounces per ton ("oz/ton")) gold and 0.16% copper from a depth of 44m (144 ft), including

- 124.05m (407 ft) of porphyry mineralization at a grade of 1.17 g/t (0.034 oz/ton) gold and 0.36% copper from a depth of 212m (695 ft).

Exeter's Chairman, Yale Simpson, stated: "The onset of winter curtailed our drilling prematurely but we managed to show that the target zone has a minimum footprint of some 600 metres (1,968 ft) in a WNW-ESE direction and 500 metres (1,640 ft) in a NNE-SSW direction. Based on drill logs and assay data, supplemented by geophysics, the zone remains untested west of the collar positions of drill holes CSD-015 and CSR-020. It is also open east of the collars of CSR-019 and CSD-026 and to the south of CSR-023 and CSD-014. On the basis of these observations and the +800 metre (2,624 ft) vertical extent of mineralization in drill hole CSD-015, the potential volume of gold-copper mineralization is very large.

"One of two uncompleted "scissor" diamond holes CSD-025 returned excellent grades in the top 336 metres (1,102 ft) of the hole. This confirmed our grade interpretation from earlier drill holes CSD-015 and CSD-016. The second scissor hole, CSD-026, was still within the argillic lithocap rock above the target zone when it was suspended at 209 metres (685 ft). Both scissor holes will be completed in October to a depth of at least 750 metres (2,460 ft).

"We are very encouraged by the oxide grades in holes CSR-013, -020, -022 and -023. We believe that the oxide blanket is extensive and has excellent potential for a heap leach gold operation similar to the nearby Refugio gold mine.

"We have planned and budgeted for 46,000 metres (151,000 ft) of drilling to establish a NI 43-101 resource estimate for both the oxide gold blanket and the underlying gold-copper porphyry. We continue to be very encouraged by Caspiche, as the grade of mineralization and the size of the target zone compares very favourably with the published mining reserve(ii) for the Cerro Casale deposit, located 10 kilometres south of the Caspiche discovery."

(ii) Cerro Casale deposit has a grade of 0.69 g/t (0.020 oz/ton) gold and 0.25% copper (based on a mineral reserve of 22.9 million oz gold and 5.8 billion pounds of copper (Kinross Gold NI 43-101 Report, March 21 2007) - 1,031,000,000 metric tons.)

Summary of Caspiche Mineralized Intercepts to the End of the Summer 2008 Drill Season

Please find the results under the following link: http://www.irw-press.com/dokumente/table_exeter_engl.pdf

Results of all drill holes are tabulated above (new holes have numbers above 016). The reverse circulation percussion drill holes (prefixed CSR) tested the broader zone of oxide mineralization above and peripheral to the porphyry gold-copper target.

(i) Suspended due to onset of winter conditions with drilling due to recommence in October.

The Caspiche porphyry stock consists principally of an early diorite porphyry and an inter-mineral quartz diorite porphyry, that intrude a pre-mineral microdiorite in the north of the area drilled. Remnants of the andesitic volcanic host rocks overlie the intrusive stock. Hydrothermal alteration is zoned from potassic in the center and at depth, to advanced argillic in the upper parts of the system.

All diamond holes have been drilled at a declination of 60 degrees on azimuth 060 degrees except for hole CSD-024, which was drilled at a declination of 65 degrees on azimuth 250 degrees, and holes CSD-025 and -026 which were drilled at declinations of 65 degrees on azimuth 240 degrees. Drill hole CSD-018 was sited 500m (1,640 ft) to the northwest of the main Caspiche target to test a separate geophysical target. No significant mineralization was encountered.

Five drill holes (CSR-019, CSR-020, CSR-021, CSR-022 and CSR-023) were drilled with a reverse circulation percussion rig, to test the near surface oxide zone. All were drilled at a declination of 60 degrees to the northeast (see plans below).

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 not been calculated using a gold cut-off grade, or with any cutting of high grades.

All diamond drill core samples are split on regular two metre intervals and represent either sawn half HQ-size or NQ-size core. Reverse circulation drill samples are collected using a cyclone in one metre intervals; all samples are then composited into two metre samples. Gold samples were prepared and assayed by fire assay (50 gram charge) whilst copper was assayed with a four acid digestion and atomic absorption spectroscopy (AAS). The primary laboratory is ALS Chemex in Chile, an ISO-9001:2000 certified laboratory. Standard, blank and duplicate samples are used throughout the sample sequence as checks for the exploratory reverse circulation and diamond drilling.

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 plans to commence a 46,000m (151,000 ft) drilling program on its Caspiche gold-copper discovery (option over 100% of the project) in October, 2008 following the southern winter. The project is located between the Refugio mine (Kinross Gold Corp.) and the giant Cerro Casale gold project (Barrick Gold Corp. and Kinross Gold Corp.).

The Cerro Moro Gold-Silver Project (100% owned by Exeter) in Santa Cruz Province, Argentina, is generating high grade to 'bonanza grade' drilling results within 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 March, 2008, Exeter signed a "Heads of Agreement" with Santa Cruz government owned Fomicruz, whereby Fomicruz may acquire a 5% equity interest in Cerro Moro upon mine permitting. Exeter may earn an 80% equity interest in prospective lands surrounding Cerro Moro that are currently controlled by Fomicruz.

As a result of anti-mining legislation passed in 2007 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 the 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 plans to explore 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.
