In 2019, Goldberg Resources<\/strong> conducted a comprehensive due diligence of the geological information collected by several companies that had previously visited the Caballos prospect<\/strong>. This review revealed compelling evidence of a copper porphyry system<\/strong>, particularly in the eastern portion of the property, east of the Pocuro Fault<\/strong>, where D-type veins<\/strong>\u2014a key indicator of porphyry-style mineralization\u2014were identified, pointing to priority targets for future exploration.<\/p>\n\n\n\n

The Caballos prospect is located near the town of Putaendo<\/strong> and comprises approximately 16,000 hectares<\/strong> of mining concessions. These concessions are situated within the Miocene Metallogenic Belt<\/strong>, home to major mining projects such as Los Pelambres<\/strong> and Vizcachitas<\/strong>, which host significant copper and gold reserves\u20141,488 million tonnes of copper<\/strong> at Los Pelambres and over 3 million tonnes<\/strong> at Vizcachitas. The property is transected from north to south by the Pocuro Fault System (PFS)<\/strong>, which likely served as a conduit for intrusive activity, giving rise to a hydrothermal system that enriched the area with various base metals.<\/p>\n\n\n\n

Between 2011 and 2013<\/strong>, several geological reconnaissance campaigns were carried out by different companies. These efforts revealed andesitic volcanic sequences<\/strong> that were folded and deformed by the PFS and intruded by multiple igneous bodies. Two intrusives are of particular interest: an alkaline intrusion<\/strong> in the northern sector, and a felsic intrusion<\/strong> with limonitic alteration to the northwest. In the central area of the prospect, quartz-sericite alteration<\/strong> and quartz veins<\/strong> mineralized with copper oxides were identified. The southern sector has emerged as the most promising for exploration, where tourmaline-associated alteration<\/strong> and outcropping breccia bodies<\/strong> were observed. It is also in this area where the D-type veins<\/strong> were found\u2014characteristic features of copper porphyry systems.<\/p>\n\n\n\n

Geophysical data further supports the mineral potential of the area. Magnetic and electrical surveys<\/strong> were carried out in 1998 by Quantec<\/strong>, followed by another electrical survey in 2006 by Zonge<\/strong>. The latter revealed strong chargeability responses at approximately 100 meters depth<\/strong>, suggesting the possible presence of sulfide mineralization.<\/p>\n\n\n\n

Additionally, geochemical sampling campaigns<\/strong> were conducted in 2007 and 2011<\/strong>, collecting a total of 227 samples<\/strong>. These were analyzed and interpreted by Goldberg Resources with a focus on identifying anomalies in copper, sulfur, and arsenic<\/strong>, which could define exploration targets. The geochemical data was interpolated and processed using geostatistical methods<\/strong>, revealing anomalies aligned along the PFS from north to south\u2014providing further support for the geological model proposed by Goldberg.<\/p>\n\n\n\n
