THE DRILL SERGEANT: Dark Horse Resources (ASX: DHR) ecently copleted work on the company’s two major gold projects in Argentina: Las Opeñas in San Juan and Cachi in Santa Cruz.
Dark Horse Resources completed a first phase drilling program at Las Opeñas, resulting in the confirmation of some high-grade mineralised zones to moderate depths from surface and providing justification for the company to proceed to a second phase of drilling.
Other work involved mapping and geophysical programs carried out over some of the mineralised Cachi targets and have provided drill targets for planned drilling later in 2019 following the winter season.
Dark Horse undertook a 17-hole program at Las Opeñas testing known, but previously undrilled, high-grade gold, silver and base metal rich quartz veins discovered during surface mapping and sampling by previous owners.
The previous companies did not test these veins but focused drilling on an adjacent bulk tonnage, low-grade phreatomagmatic breccia target.
Most of the best intersections achieved in the recent drilling were made below the weathered, supergene zone, in primary mineralisation showing that grade persists at depth.
At the Chaci property in Santa Cruz Dark Horse completed mapping, ground magnetic, Induced Polarisation (IP) and rock‐chip sampling programs.
Although it is yet to receive all assay results, the company indicated it had sufficient results from the current program and prior programs to enable it to identify nine mineralised targets within the Cachi property, the five mains ones being Vetas Cachi, Morena, Vetas NW, Patricia and Puma.
Some of these targets have been prioritised for further work to assist with designing a drilling program, planned to commence following winter in the last quarter of 2019.
