Vancouver, B.C., February 2, 2009 - Exeter Resource Corporation (NYSE Alternext US:XRA, TSX-V:XRC, Frankfurt:EXB - "Exeter" or the "Company") reports that drilling at its Caspiche project in Chile has further extended the porphyry system to the southwest, returning 488 metres (1,601 feet) at a grade of 1.30 grams per tonne gold (0.038 ounces per ton) and 0.44% copper, in drill hole CSD032. This intercept is part of a 930 metre (3,051 feet) interval that assayed 0.89 grams per tonne gold (0.026 ounces per ton) and 0.31% copper. Importantly the mineralization continues further down hole, with assays awaited for the remaining interval of 342 metres (1,122 feet), from a down hole depth of 1,025 metres (3,362 feet).
New results include:
CSD032, drilled to test the southwestern limits of mineralization, intersected:
CSD031, drilled to test the northeastern limits of mineralization, on the same drill section as CSD032, intersected:
CSD030, drilled to test the northwestern limits of mineralization, on a section line 400 m north of CSD032, intersected:
Exeter’s Chairman, Yale Simpson, stated, “Drill hole CSD032 shows some of the best gold-copper grades to date on the property, and moves the “centre of gravity” for the highest grade mineralization further to the southwest. Importantly, the drill intercept is preliminary as our geologists report visual mineralization (yet to be assayed) continues further down the drill hole.
“The mineralized zone on the CSD032 section line appears to be closed off to the east by drill hole CSD031, but remains open to the west. With the high grades returned in CSD032, another drill hole is tentatively planned west of CSD032 to undercut that hole.
“CSD030, located on a section line 400 metres (1,312 feet) northwest of CSD032, is important as it returned +800 metres (+2,624 feet) of economic tenor gold-copper mineralization. As the mineralized body remains untested to the west of CSD030, further step out drilling is under consideration in that direction.
“Based on our drilling to date, we are increasingly confident that Caspiche is one of the best Chilean gold-copper discoveries in many years. Drilling is continuing, with three rigs operating on a 24 hour/day basis to meet a second quarter 2009 timeline for completing a NI 43-101 compliant resource estimate.”

Quality Control and Assurance
Drill intercepts presented above are drill intersection widths and may not represent the true widths of mineralization. Gold and copper assay results presented have not been calculated using a gold cut-off grade, or with any cutting of high values. 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 or four metre samples. Gold samples were prepared and assayed by fire assay (50 gram charge). Copper was assayed with a four acid digestion followed by atomic absorption spectroscopy. 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 had $23 million in its treasury as at September 30, 2008.
The Caspiche gold-copper discovery is situated in the Maricunga gold district of Chile, between the Refugio mine (Kinross Gold Corp.) and the giant Cerro Casale gold deposit (Barrick Gold Corp. and Kinross Gold Corp.). Drilling is currently underway to produce an interim NI 43-101 compliant inferred resource estimate in the second quarter of 2009. The initial resource target is large, reflecting the scale of similar gold and/or gold-copper porphyry systems in the immediate area.
Exeter’s priority on its Cerro Moro high grade gold-silver property in Argentina is to focus exploration on the Escondida vein, where drilling has returned multiple drill intercepts of 12-18 g/t gold equivalent* over potentially mineable widths. The results from current drilling will be used to produce a NI 43-101 compliant resources estimate, expected during the second quarter of 2009. Exeter will continue to develop its conceptual models so that on receipt of a NI 43-101 resources estimate, it can advance the project to the scoping study level.
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.
* 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.
