Exeter Resource Advances Caspiche Development - Drilling Program Underway

VANCOUVER, Feb. 21, 2017 - Exeter Resource Corp. (NYSE-MKT:XRA) (TSX:XRC) (Frankfurt:EXB) (“Exeter” or the “Company”) is pleased to announce that it has commenced a 6,000 metre drill program on its 100% owned Caspiche gold-copper project in Chile.

The program, contracted to Synergy Drilling, is designed to improve the definition of the known oxide gold zone and other potentially leachable gold zones currently not included in the oxide gold heap leach mine plan.

While the gold oxide zone is well defined by previous drilling, the current program will bring confidence levels to feasibility standards, a necessary component of our plan to move Caspiche oxides to a production decision.

Importantly, material within a transition zone below the oxides is known, but not well defined. Drilling and metallurgical testwork on this material opens the potential to add to the resources amenable to heap leaching.

Upon completion of the drilling program, Exeter expects to initiate advanced studies on the project using updated capital and operating cost estimates. Alternative infrastructure requirements associated with a recently optioned desalinated water will also be assessed (refer to the Company’s press release dated January 17, 2017 - “Exeter secures second water source”).

Caspiche is one of the largest gold discoveries made in Chile in recent years. Unique characteristics of the deposit include its’ sizeable heap leachable zone and a lower, discrete higher grade gold-copper core, within a low grade envelope. This combination offers mining opportunities that range from modest scale heap leach gold production, to larger scale open pit/underground mining of the gold-copper zone.

Development options were assessed for Caspiche in the Preliminary Economic Assessment (“2014 PEA”)^A released in 2014. This report reviewed three potential development alternatives, all of which require significantly less capital than earlier studies.

In the 2014 PEA, the heap leach oxide gold project produced a projected average of 122,000 oz AuEq* annually over a planned 10 year mine life, including 148,000 oz AuEq* annually in the first five years. The proposed project has a very low strip ratio (0.27:1) and favorable gold recoveries.

Over the course of the last 18 months, the Company optimized Caspiche oxide development requirements, including detailed metallurgical studies. Importantly, the Company advanced infrastructure alternatives, including securing a second water source.

Wendell Zerb, Exeter's President & CEO and a “qualified person” ("QP") within the definition of that term in National Instrument 43-101, Standards of Disclosure for Mineral Projects, has reviewed and approved the technical information in this corporate update.


About Exeter

Exeter is a Canadian mineral exploration company focused on the exploration and development of the Caspiche project in Chile. The property is situated in the Maricunga gold district, between the Maricunga mine (Kinross Gold Corp.) and the Cerro Casale gold deposit (Barrick Gold Corp. and Kinross Gold Corp.). The discovery represents one of the largest mineral discoveries made in recent years.

On December 19, 2014, Exeter announced the filing of an Amended NI 43-101 Technical Report on the Caspiche Project (“2014 PEA”). Refer to the Exeter web site or Sedar for details regarding the 2014 PEA.

The Company currently has cash reserves of C$16 million and no debt.

	The 2014 PEA used prices of: Au US$1,300 US$/oz., Ag US$20/oz. and Cu US$3/lb.
*	Gold equivalent oz (AuEq) value is based on Au, Ag and Cu revenues (prices and recoveries involved). AuEq oz [troy oz] = [Au g/t * Rec Au * tonnes]/31.1 + [Ag g/t * Rec Ag * tonnes]/31.1* silver price troy oz/ gold price troy oz + [[Cu% * Rec Cu * tonnes]*2204] * copper price lbs/gold price troy oz. Recoveries are adjusted based on metallurgical characteristic of the resource.

Cautionary Note to United States Investors - The information contained herein and incorporated by reference herein has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. In particular, the term “resource” does not equate to the term “reserve”. The Securities Exchange Commission’s (the “SEC”) disclosure standards normally do not permit the inclusion of information concerning “measured mineral resources”, “indicated mineral resources” or “inferred mineral resources” or other descriptions of the amount of mineralization in mineral deposits that do not constitute “reserves” by U.S. standards, unless such information is required to be disclosed by the law of the Company’s jurisdiction of incorporation or of a jurisdiction in which its securities are traded. U.S. investors should also understand that “inferred mineral resources” have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Disclosure of “contained ounces” is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.
