Argentina Gold Project 

 

Location: Central-Eastern region of Santa Cruz, Argentina 

Dark Horse holds a large portfolio of prospective gold-silver properties in Santa Cruz and Rio Negro provinces. 

The the most advanced property is the Los Domos Project covering a combined area of approximately 105km2, in three exploration licences.  

The region is host to numerous multi‐million ounce, epithermal style gold‐silver deposits within Santa Cruz Province including Cerro Vanguadia owned by AngoGold Ashanti, and Cerro Negro owned by Goldcorp.

The Los Domos Project is considered prospective for gold and silver mineralisation associated with rhyolitic dome structures and epithermal quartz‐chalcedony vein / breccia systems and is under a farm‐in agreement between Dark Horse and the Argentinean vendors as outlined in the Company’s ASX release of 22 November 2016.

The Los Domos Project lies within the east-central part of the Deseado (60,000 km2) Massif in the Santa Cruz province of Argentina.  The Massif is dominated by extensive Jurassic volcanic and intrusive rocks, in which older andesitic and basaltic units are overlain by rhyolites, ignimbrites, and volcaniclastic rocks.  

Cretaceous lake beds overlain by Tertiary and Quaternary alkali basalts partly cover the Jurassic volcanic plateau.  The Deseado Massif hosts numerous low-sulphidation, epithermal, precious-metal quartz vein and vein-breccia deposits that appear to have closely followed the Jurassic acid volcanism host several including multimillion ounces Au-Ag deposits as Cerro Negro (Goldcorp), Cerro Vanguardia (Anglo Gold) and several small gold projects.


La Punta Target 

Within the Los Domos project area, there are several exploration targets with the most prominent target named La Punta which covers an ellipsoidal area approximately 1,000m x 500m at the intersection of two structural corridors.  Rock chip samples have returned anomalous high gold values, with the two highest returning 1.57 g/t Au, 56.7 g/t Ag (sample DH007) and 0.92 g/t Au, 13.8 g/t Ag (sample DH008).  Both samples also returned high arsenic values (74 and 624 ppm respectively) and sample DH008 gave elevated mercury content (20 ppm). 

Dark Horse is currently carrying out detailed geological mapping and sampling for assaying, and will be carrying out geophysical surveys over the next three months, with the objective to define drill targets for a program in late 2018.
