Dark Horse Resources Confirms High Grades at Las Opeñas Gold Project

THE DRILL SERGEANT: Dark Horse Resources (ASX: DHR) has completed detailed mapping and a diamond‐sawn rock channel sampling program at the company’s Las Opeñas gold project in Argentina.

Dark Horse Resources declared the recent work had confirmed widespread high-grade zones of gold and silver.

The channel sampling consisted thirty‐four channel samples cut over a two-kilometre strike length of the Presagio mineralized zone, and nine samples cut over the Vultur mineralized zone.

Of these, seventeen produced gold assays in excess of one gram per tonne and another five of gold grades in excess of 5g/t.

The highest gold grade was 54g/t and the highest silver grade was 739g/t.

Best sample results returned with the highest gold grades included:

0.4m at 54.2g/t gold, 83g/t silver
0.8m at 17.9g/t gold, 225g/t silver
0.7m at 10.4g/t gold, 263g/t silver
1.0m at 7.2g/t gold, 271g/t silver
0.8m at 7.7g/t gold, 336g/t silver
0.8m at 4.1g/t gold, 384g/t silver
1m at 2.5g/t gold, 597g/t silver

Before undertaking the detailed mapping and surface exploration, Dark Horse had carried out a first phase drilling program in March-April this year that identified five mineralised vein systems at Las Opeñas, with the Presagio vein target showing the most promising results.

Detailed mapping of the Presagio vein system identified the existence of an altered corridor of more than 2.5km in length, including a 1km long vein‐breccia system containing high gold‐silver grades with massive sulfides, located to the west of a drillhole area investigated during the March‐April 2019 drilling program.

Dark Horse considers the exploration results indicate gold and silver mineralisation is most prevalent where northeast and northwest faults intersect, which it acknowledged to be is common at Las Opeñas.

“The gold‐silver mineralisation is distributed throughout the system in parallel, on‐echelon structures,” Dark Horse Resources said in its ASX announcement.

“A hypothetical geological model of Presagio has been interpreted by the company’s geoscientist team and shows the target mineralisation at depth.

“Positive results of this discovery will be used to target further drilling, which is planned to commence in the last quarter of 2019 following the Argentinean winter.”
