Antofagasta Gold Signs Definitive Option Agreement to Acquire Approximately 293,500 Hectares (2,935 Square km) in Premier Copper Mining District-Northern Chile


TORONTO, ONTARIO--(Marketwired - Aug. 1, 2013) - Antofagasta Gold Inc. ("Antofagasta" or the "Company") (TSX VENTURE:AN) has entered into a Definitive Option Agreement to earn an 80% interest in the Atacama Copper Property ("Property"). The Property consists of approximately 293,500 hectares (2,935 square kilometers) in Chile's Antofagasta Region II, home to some of the world's largest copper mining operations and covering a large undrilled portion of the highly prospective Jurassic and Paleocene-Early Miocene copper porphyry belt.

The Property is located approximately 40 km north east from the city of Antofagasta, and is traversed by major highways, railways, desalination pipelines and high-tension power lines, some of which service existing operating copper mines in the region and are subject to easement agreements which will be assumed by the Company. The claim block follows the Antofagasta Calama Lineament covering roughly 120 km of the north south striking Chilean Copper Belt and is surrounded by several major producing copper mines. Operating mines within a 15 km radius of the Property boundary include Spence (BHP Billiton), Lomas Bayas (Glencore Xstrata), Mantos Blancos (Anglo American), Tesoro (Antofagasta Minerals/Marubeni) and Esperanza (Antofagasta Minerals/Marubeni). These mines currently account for over 600,000 tonnes of estimated annual copper production. A map showing the outline of the claim blocks and the location of the larger mines in the immediate area can be found here: http://media3.marketwire.com/docs/atacama_project.pdf.

William Randall (M.Sc., P.Geo), President & CEO of Antofagasta Gold, commented: "We are excited to commence exploration on a significant land package that is virtually unexplored, situated in the heart of the world's premier copper mining district. The location, size, scope and history of this exceptionally large property package make it a rare and unique opportunity, and significant event, for Antofagasta Gold and its shareholders."

Most of the copper porphyry deposits in the region belong to the Paleocene-Early Eocene world class Copper - Molybdenum porphyry belt which extends from southern Peru to northern Chile for a distance of over 1300 km. The Spence copper - molybdenum mine, one of the more recent major discoveries in the immediate region, is located 4 km west of the Atacama Copper property boundary. The property was discovered under 60 metres of gravel cover by Rio Algom in 1996 and is related to three Paleocene dacite porphyry intrusive and tourmaline breccias aligned north east - south west. Spence has a 20 m thick oxide zone followed by a well developed enrichment blanket averaging approximately 60 m in thickness. The deposit lies on the intersection of prominent north east and north west trending structural lineaments.

Vernon Arseneau (P.Geo), VP Exploration of Antofagasta Gold, commented: "It isn't often that geologists get the opportunity to explore such a large area that is both strategically located and has seen little to no previous metallic exploration work. The area was previously held by industrial minerals focused groups that did not explore for copper deposits. In some cases these claims have gone unexplored for base and precious metals since the late 1800's. Our team is already working in the area and we are ready to start exploration using our current field base and personnel. Compilation work has commenced will continue as the first phase of the work program in order to ensure a full data set for target selection and initial ground work."

Terms of the Agreement

Antofagasta has entered into a four year definitive option agreement to earn an 80% interest in the Atacama Copper project (the "Option Agreement").

The Company will be able to exercise the option on a maximum of 50,000 ha (500 square kilometers) at its discretion. The Company is not restricted in the selection of the area it chooses to retain, allowing it to retain the high priority targets it successfully identifies in the early stage exploration program.
