Objective of gold projects is the discovery and definition of several multimillion ounce gold deposits by:
Targeting epithermal gold systems in proven gold regions and mining friendly provinces in Argentina.
The Las Opeñas Gold Project is on the border of the Indio Belt, Argentina, where there are multi-millon-once gold deposits including Veladero (12Moz) and Pascua Lama (18Moz).
Located in the north-western region of the mining friendly province of San Juan, Argentina.
Lease has an area of 1,462ha and lies at an elevation between 2,800m and 3,500m (relatively low altitude for this gold region) and free of glacier and periglacial geoforms.
Has excellent access - 30 km from Rodeo township, and 200 km from San Juan city, enabling year-round work. Well-maintained public gravel road connects the projects to the nearest village of Angualasto approximately 20 km to the south. The property has water availability all year.
Las Opeñasis an Intermediate Sulfidation Epithermal System showing a mineralized breccia hosting a gold porphyry system in the south-west, and several epithermal gold vein systems in the central-west, all aligned in local and regional structures.
The Las Opeñas breccia has similar geological characteristics to the Gold Fields, Salares Nortes - a high grade gold and silver deposit in Chile. This deposit has over 2 million ounces of gold below 100 meters of depth, with a surface expression of only 200 by 300 meters.
The Las Opeñas breccia has large areas which have not been drill tested, which could host at least five Salares Nortes sized deposits, a primary target for Dark Horse.
Prior to 2014, the property was explored by Teck Resources and Genesis Minerals. They focussed on discovering a large porphyry in the breccia system, though did minimal work on the vein systems.
Dark Horse took over the projects primarily to focus on the epithermal gold system where gold-silver mineralization occurs in high grade veins, vein breccias and stock work zones, principally in a granite.
Dark Horse investigations have discovered that Las Opeñas vein systems are demonstrating high grade gold and silver intercepts along significant strike lengths.
Dark Horse completed a first phase drilling program (Reverse Circulation drilling) in March-April 2019 in previously undrilled areas, which has resulted in the confirmation of high grade mineralised zones to moderate depths from surface and provided the justification for proceeding to a second phase of drilling. Promising assay results were identified at the Tramway and Presagio vein targets in table, right.
Presagio surface sampling May-June 2019 was 34 Diamond Channel Samples cut over 2km strike length. Five samples have gold grades in excess of 5g/t.
0.4m @ 54.2g/t gold, 83g/t silver
0.8m @ 17.9g/t gold, 225g/t silver
0.7m @ 10.4g/t gold, 263g/t silver
1.0m @ 7.2g/t gold, 271g/t silver
0.8m @ 7.7g/t gold, 336g/t silver

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.
