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 Cachi Gold Project has a prime geological setting, significant high value assays from surface exploration, and a detailed drilling program in planning for the summer of 2019/2020.
Dark Horse Resources has an extensive portfolio of gold properties in the Santa Cruz and Rio Negro provinces of Argentina. The exploration of these properties is primarily in search of near surface epithermal vein systems. Across these properties the Cachi Gold Project is currently the most advanced and major target of Dark Horse.
Cachi Gold Project is a 46,892ha lease package located in the central‐western region of Santa Cruz Province, Argentina. The region is host to numerous multi‐million‐ounce, epithermal style gold‐silver deposits including Cerro Vanguadia owned by AngloGold Ashanti, and Cerro Negro owned by Goldcorp.
Cachi Gold Project is located in a prime position, in the heart of advanced, high grade precious metal deposits. It is bordered to the west by Circum Pacific’s Sierra Morena Project, to the east by Patagonia Gold’s Las Mellizas Project and very close to Panamerican Silver’s advanced Joaquín and Cose projects.
The whole system is anomalous in gold and silver (averaging 1-4 g/t Au) with individual results up to 9.7 g/t gold. Arsenic, antimony and molybdenum
are all elevated, indicating that the system is fertile.
The types of quartz found in most of the veins on the property, suggests that the deposit is relatively high in the epithermal system.
Prior to Dark Horse Resources holding the property, the project had not been examined comprehensively. IamGold carried out general reconnaissance exploration, and De Grey Mining carried out rock chip, lag sampling and geophysics, as well as drilled several diamond holes in the vein breccia zone target of the adjacent Sierra Morena Project.
The particular geological setting of Cachi Gold Project, is due to a specific sequence of volcanic intrusions, which has brought the precious metal, mineralized fluids into the system. The project is that of a caldera complex developed in the older volcanic rocks of the Chon Aike Formation. Within the caldera there is a felsic volcanic center filled with younger volcanic rocks and rhyolite domes of the La Matilde Formation. The precious metal mineralization, in many of the Santa Cruz mines, has been dated to this onset of the La Matilde volcanic event.
Mapping, ground magnetics, Induced Polarisation (IP) and rock-chip sampling programs have recently been completed at the Cachi property.
15 large mineralised targets have now been identified within the Cachi property, with the five main ones being Vetas Cachi, Morena, Vetas NW, Patricia and Puma. Results of these mineralized targets, point to the Cachi Gold Project as having significant potential for the discovery of a large precious metal system,similar to others in the region.
