About Exeter

Exeter is a Canadian mineral exploration company focused on the discovery and development of gold and silver properties in South America . The Company has C$79 million in its treasury.

On the Caspiche Project in Chile , Exeter recently announced an inferred mineral resource estimate of 1, 117 Mt (million metric tons) at a grade of 0.55 grams per metric ton gold and 1.12 grams per metric ton silver, including 1, 017 Mt at a grade of 0.22% copper. This equates to in-situ inferred resources of 19.6 million ounces of gold, 40 million ounces of silver and 4.84 billion pounds of copper (a total of 32.4 million gold equivalent ounces*). Drilling with six rigs to expand and upgrade the resource estimate is underway.

On the Cerro Moro Project in Argentina , Exeter recently announced an initial inferred mineral resource estimate of 646,000 ounces gold equivalent(xx) at a grade of 18 grams per ton gold equivalent(xx). The Company has drilled over 200 infill holes on the Escondida vein structure, principally to upgrade the sectors of the inferred resource that might be scheduled for early mining. Drilling to expand the deposit has recently been initiated and will continue through 2009. Engineering, environmental and infrastructure studies are being advanced ahead of a scoping study in 2010.

Matthew Williams , Exeter's Exploration Manager and Justin Tolman , Exeter's Caspiche Project Manager both considered a "qualified person" within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has supervised the preparation of the technical information contained in this news release.

*Gold ("Au") equivalence for copper ("Cu") and silver ("Ag") was calculated by Exeter using assumed metal prices of US$800/ounce ("oz") for Au, US$12/oz for Ag and US$2/pound for Cu. The formula to calculate Au equivalence for Cu was pounds of Cu multiplied by 2 and divided by 800; Au equivalence for Ag was calculated using the formula oz of Ag multiplied by 12 and divided by 800, and in both cases assumes 100% recovery. Reported grades and metric tons have been rounded (see news release NR 9-22 dated October 20 , 2009).

(xx)Inferred mineral resource estimate of 1,098 Mt containing 371,000 ounces gold at a grade of 10.5 g/t and 19.2 million ounces silver at a grade of 545 g/t for 646,000 ounces gold equivalent at a grade of 18 g/t gold equivalent. Gold equivalent is calculated by dividing the silver assay result by 70, adding it to the gold value and assuming 100% metallurgical recovery (see news release NR 9-14 dated July 8 , 2009).
