VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 02/27/14 -- Exeter Resource Corporation (NYSE MKT:XRA)(TSX:XRC)(FRANKFURT:EXB) ("Exeter" or the "Company") is pleased to announce that its Chilean subsidiary, Minera Eton ("Eton"), has negotiated new joint venture ("JV") terms (see News Release dated June 3, 2013) with the Chilean subsidiary of Canadian company Atacama Pacific Gold Corporation ("Atacama"). The amended JV allows Eton to earn an additional 40% interest, for an aggregate 90% interest, in water exploration tenements Cuenca Two and Laguna Verde (West, East) in the Maricunga region, northern Chile. Importantly, the JV has approved the camp mobilization and water drilling is expected to commence within 10 days.
President and CEO of Exeter, Wendell Zerb, states, "Based on historical water exploration and new geophysical studies at Laguna Verde, we are optimistic this drilling campaign will identify new water resources that could, in due course, lead to securing our water requirements at Caspiche".
To earn the additional 40% interest, Eton is required to incur an additional 40% (total of 90%) of all expenditures relating to exploration and potential development of water on the Cuenca Two and Laguna Verde water tenements. In addition, upon the discovery and approval of water rights by the General Directorate of Water Resources ("DGA"), Eton will assume Atacama's obligation to pay Hydro Exploranciones SpA ("Hydro"), an Atacama affiliate, US$15,000 per litre per second ("l/s") of DGA approved water rights. Atacama will remain obligated to pay Hydro US$15,000 per l/s on its 10% interest. Regardless of the total amount of DGA approved water acquired by the JV, payments to Hydro are capped at US$1 million. These payments are not applicable to Eton's original 50% interest in the JV.
The JV partners have hired Terraqua, a specialist Chilean water drilling contractor, to complete a US$1.5 million drilling program, consisting of up to 3, 12 inch diameter production holes, on the Laguna Verde water tenement.

The objective of the water program is to identify, evaluate, and secure water sources to support a potential initial heap leach gold stage and a follow-on gold-copper sulphide stage of mining at the Company's Caspiche gold-copper project in Chile.
Preliminary internal studies relating to developing Caspiche as a smaller scale, staged mine indicate potential for a significantly lower water requirement from that outlined in previous studies. Previous studies for the large scale open pit mining operation indicated water requirements of approximately 1,000 l/s. Current expectations, based on the preliminary objectives outlined, are that water requirements could be 50 l/s for the standalone oxide operation(ii) and potentially as low as 150 l/s to 250 l/s for the sulphide mine development(ii).
Caspiche Project Update
The Company's review of lower capital alternatives for the potential development of the Caspiche project are progressing (see News Release dated September 23, 2013). Options being assessed include open pit mining of the near surface oxide zone (gold only), followed by a deepening of the open pit and underground mining of the central, higher grade portion of the gold-copper sulphide deposit.
Preliminary studies conducted by Santiago based engineering consultancies, NCL Construccion y Ingenieria and Alquimia Conceptos S.A. are ongoing. Trade off studies continue as a means to determine the most viable alternatives for potential development. As part of these initial studies, Exeter is reviewing production options that not only provide the best economics, but also lead to best industry practice for water conservation and environmental impact. Further information regarding these reviews is expected over the next quarter.
Development Concept for the Oxide Gold Zone
In the Company's January 2012 Pre-Feasibility Study, gold within oxidized material was to be mined as part of the large scale open pit operation. High throughput (70,000 tonnes per day) levels provided solid economics under the framework of a large scale operation. In order to reduce initial capital while expanding the oxide mine life, Exeter is evaluating a reduced throughput mine, targeting 100,000 ounces of gold production per year (30,000 tonnes per day) over a 10 year mine life(ii).
Oxide Gold Study Objectives(ii):
-- Target a 10 year mine life to produce 100,000 ounces gold annually. -- A reduced initial capital requirement. -- Maintain a very low strip ratio and the rapid leach kinetics achieved in previous studies. -- Reduce the project water requirements. -- Consider the trade off potential for on-site power generation versus grid power.
Development Concept for the Gold-Copper Sulphide Zone
The higher grade gold-copper sulphide zone at Caspiche has dimensions of up to 500 metres ("m") by 300 m by +1,000 m vertically. It is associated with a defined, strongly mineralized diorite porphyry unit. Both copper and gold recoveries have been shown to be higher in this unit and higher concentrate grades can be achieved, according to existing test work.
The preliminary studies continue to evaluate options for more selective mining of the higher grade zone. This includes trade off studies evaluating initial open pit access to the zone by deepening the open pit, followed by underground development. New modeling for the underground operation assumes selective, top-down, open stope mining methods, rather than the bottom-up (block cave) approach set out in the January 2012 Pre-Feasibility Study. The objective is to accelerate access to the higher grade zone and the deferral of capital expenditures.
Targeted peak throughput is 27,000 tonnes per day(ii), representing a potential scale of peak annual gold equivalent(i) production from the underground operation of 350,000 ounces(ii).
Sulphide Study Objectives(ii):
-- Review the uniformity of the higher grade sulphide zone. -- Confirm that it lends itself to large scale, sub-level open stope mining. -- Confirm the practicality of underground access using two declines, one of which is dedicated to high capacity conveyor haulage and determine that an underground crushing and conveying system will support the large scale mining initiative. -- Confirm that a top down mining approach will reduce the development time compared to other underground bulk mining alternatives. -- Confirm the conceptual practicality of using tailings for paste fill of the primary and secondary stopes. -- Reduce initial capital requirements. -- Reduce the project footprint - minimal waste rock, a smaller tailings requirement, and a smaller concentrator plant. -- Reduce electricity and water requirements.

Expanded Column Leach Test Work
To enhance previous metallurgical studies relating to Caspiche oxide gold mineralization, Exeter has engaged McClelland Laboratories International ("MLI") of Reno, Nevada to conduct a series of new studies. MLI are currently leaching 11 large diameter columns (10" to 12" diameter, each up to 280 kilograms). The sample composites were selected to be representative of a conceptual open pit mining schedule. In addition, data will be forthcoming on near-surface gold-bearing material that had not been part of previous conceptual mine plans.
The composites are comprised of individual 8 m intercepts, each of which will be tested in 96 hour, 1.7 mm bottle roll tests. Previous MLI work indicated a useful correlation between relatively quick bottle roll tests and column tests. Confirmation of this trend may allow mine blast hole cuttings to be bottle roll leached to provide a reasonable prediction of heap leach recoveries. Additional physical studies form part of the program to confirm crushing parameters and heap stability. Final results are expected to be available in Q2/14.
Earlier column testwork indicated an optimum crush size of 50 mm, relatively rapid leach kinetics and an average gold recovery of 78%.
Caspiche Surface Easement Update
On June 6, 2013 the Chilean government granted Eton a surface easement (access right) over both the Caspiche project and adjacent lands considered suitable for potential mine infrastructure. Since that time Eton has been making cash payments to the government to fulfill its obligations under the easement agreement. On January 27, 2014, Eton was served with a court claim filed by a private Chilean mineral exploration company, Compania Minera Cerro del Medio SCM ("Cerro del Medio") challenging the Chilean Government's granting of the surface easement to Eton. The claim, filed before the Santiago Civil Court, is against the Chilean Government and Eton.
Under Chilean law there are provisions to provide necessary surface access for the development of mineral deposits. The Caspiche easement includes surface access rights over sections of Cerro del Medio's adjacent mineral tenements. Cerro del Medio is citing "non-compliance by the Chilean Government of certain legal formalities required to approve the easement" and "that the easement granted overlaps Cerro del Medio's Santa Cecilia project mining properties". Based on public disclosure, there are currently no defined mineral resources associated with Cerro del Medio's mining tenements.
A review of the claim by Eton's Chilean legal counsel has concluded that the Cerro del Medio claim has no grounds under Chilean law and should be rejected.
La Buena Joint Venture Project - Mexico
Exeter has informed San Marco Resources Inc. that results from exploration at the La Buena project have not met Company objectives and that it is terminating the joint venture agreement.
The Phase I Drill Program at La Buena included the completion of four drill holes. The drilling targeted both geological and geophysical targets without returning economically significant results.
