Antofagasta Gold Provides Exploration Results for Its Capricornio Project, El Penon Gold District, Chile
22.08.2013 | Marketwired
TORONTO, ONTARIO -- (Marketwired - Aug 22, 2013) - Antofagasta Gold. ("Antofagasta" or the "Company") (TSX VENTURE:AN) has received the final set of drill results from its drill program at the Company's wholly-owned Capricornio Property ("Capricornio"), located approximately 80 kilometres northwest from the El Peñon Gold Mine (Yamana Gold) and 20 kilometres west from Xstrata's producing Lomas Bayas Mine and immediately south of its 2.935 square kilometre Antofagasta Chilean copper belt project, the Attacama copper property (See Press Release dated July 31, 2013).The drill program consisted of approximately 6,352.50 metres of HQ3 diamond drill core and was designed to confirm historical mineralized intercepts and complete a broad scale test of a regional scale epithermal gold - silver system. Upon analysis of the drill results, the following observations and interpretations were reached:
- A regional scale epithermal system consisting of quartz veins ranging from 25 metres to under 1 metre in width, trending generally north south, and covering an area approximately 3 x 4 km was defined; twenty linear kilometers of precious metal bearing vein strike has been confirmed.
- Texture of quartz in veins and replacement bodies are at and above the transition from Crustiform-Colloform Superzone to the Chalcedonic Superzone in an epithermal system (Morrison et al, 1990) and results indicate that erosion has not removed the potentially most precious metal bearing part of the system.
- Near surface gold-silver is interpreted as supergene mineralization within oxidized material in some instances.
- Short hole drilling at the central portion of the epithermal system intersected wide gold-quartz bearing veins and stockwork with extensive primary mineralization, indicating potentially the upper halo of a high grade zone to depth.
- 68% of diamond drill holes intersected quartz vein hosted gold and/or silver mineralization.
- Average grade multiplied by width of mineralized intersections is 16, consisting of a vast majority of near surface intersections.
- Limited deep drilling conducted during this campaign was successful at placing the system within the epithermal model, vectoring prospective areas, and intersecting mineralized intervals at depth within the Ilusion vein system.
- Extensive silica flooding was also encountered in other parts of the Ilusion vein, possibly remobilizing precious metals.

As indicated by previously reported fluid inclusion work, textural and geochemical features of the vein system places the current surface expression of the Capricornio epithermal system near the top of the system. Evidence supporting this interpretation can be seen in some of the recently drilled holes on Mejillones, Montevideo, Santa Rosa and some parts of the Illusion zone that intersected wide sections of multi-phase mineralized veins and veinlets over core lengths of up to 42 metres. The silica replacement bodies (silica caps) have superimposed stockworks of colloform chalcedony veinlets with pyrite or hematite box works after pyrite. Quartz textures in the silica replacement bodies varies from opaline to saccharoidal, to cryptocrystalline and locally quartz pseudomorphs coarse calcite crystals.
The more prospective areas for high grade precious metal mineralization lies below the currently drilled portions of the vast majority of the mineralized area. Of priority interest for follow-up exploration is the Santa Rosa zone near hole CAD-13-027 which intersected a well defined vein, displaying a high grade zone of 4.23 g/t Au equivalent over 4 metres (76.0 metres to 80.0 metres) of core length within a wider 10 metre (71.0 metres to 81.0 metres) zone grading 2.23 g/t Au equivalent. This hole is the deepest in the Santa Rosa zone to date and lies under an anomalous silica replacement body at surface.
Vernon Arseneau, Vice President of Exploration, commented, "Our results to date define an extremely large area of shallow mineralization (average drill hole depth); the more important results of this first phase of exploration is the very significant potential of high grade material at depth. We have completed detailed geological work, utilized international epithermal vein experts, and concur this epithermal system presents a unique opportunity to define a high grade gold-silver deposit."
