Los Domos Gold Project 

 

Location: Central-Eastern region of Santa Cruz, Argentina 

The Los Domos Project contains two exploration licences (Los Domos and Los Domos Norte) covering a combined area of approximately 105km2.  

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 project area, several exploration targets were visited but the most prominent target is named La Punta which covers an ellipsoidal area approximately 1,000m x 500m at the intersection of two structural corridors.  Of the nine rock chip samples taken during the technical due diligence program in December 2016, six were anomalously high in gold, 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).
