Andina Copper Corporation has reported significant drill intercepts from its maiden diamond drilling program at the Cobrasco copper-molybdenum project in Choco, Colombia. Results from drillhole CDH004 show wide intercepts of copper-molybdenum mineralization, following high-grade intersections previously reported in drillhole CDH003. These findings support the potential for a large-scale porphyry deposit at the site.
The importance of these results lies in the global context of copper demand. Copper is essential for electrification, renewable energy infrastructure, and technological development worldwide. New discoveries of significant copper deposits are increasingly critical as existing mines face depletion and demand continues to grow. The Cobrasco project's location along the Andean porphyry belt, a premier copper-producing region, adds strategic significance to these findings.
Drillhole CDH004, completed to 900.25 meters, intersected multiple mineralized intervals. The most significant mineralization occurred between 579 and 686 meters, where intensely fractured magmatic-hydrothermal breccias returned an average grade of 0.75% copper. This interval included a peak 2-meter assay value of 1.70% copper. The upper portion of the hole also showed anomalous copper and silver values, while sporadic gold mineralization of up to 1.06 grams per ton was reported, suggesting a possible gold-rich intrusive phase within the broader system.
Joseph van den Elsen, President and CEO of Andina Copper, stated that these results further validate the size, scale, and grade of the Cobrasco system. The company sees potential for a globally significant deposit and plans to mobilize a second drill rig to expedite exploration. Ongoing step-out drilling aims to systematically expand the footprint of the system and define its lateral extents.
Drillhole CDH005, designed to test southern extensions of the mineralized system, has been completed to 934.00 meters. Geological logging indicates continuity of intrusive phases, alteration styles, and sulphide mineralization throughout the hole, supporting the interpretation of a large and long-lived mineralizing system extending south of the currently defined drill footprint. Assays for CDH005 are pending and expected shortly.
The technical information in this release was verified by Francisco Montes, a qualified person under National Instrument 43-101. Quality assurance and quality control procedures included proper sample collection, preparation at the ALS facility in Medellin, and analysis at the ALS laboratory in Lima, Peru. Mineralized intercepts reported for CDH004 applied a 0.2% copper cut-off with maximum dilution of 20 meters.

The implications of these drilling results extend beyond the company itself, potentially contributing to future copper supply in a market facing increasing demand pressures. Successful development of the Cobrasco project could have significant economic impacts for the Choco region of Colombia while addressing global copper supply challenges.
