Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has reported an outstanding drill intercept from CDH007, the second hole completed from a new step-out drill pad at the Cobrasco Project in Chocó, Colombia. The results further expand the Cobrasco Central Cu-Mo porphyry system to the northwest and closely mirror those of CDH006, with near-surface mineralization commencing at 44m and continuing uninterrupted to 324m where a fault zone terminates the mineralized host unit and grades decrease.
Following the high-grade Cu-Mo intersections reported in recent drillholes CDH003 to CDH005 (refer March 24, 2026 News Release), a new step-out drill pad was collared to test the continuity and extension of the Cobrasco Central mineralized system to the northwest. Drillhole CDH006 was drilled to the southwest along this new section line intersecting 232m @ 0.68% Cu, 75ppm Mo, 2 g/t Ag from 38m (refer April 14, 2026 News Release). Hole CDH007 was drilled from the same pad to the northeast, in a section line parallel to previous holes CDH001 and CDH004.
Highlights from hole CDH007 include 292m @ 0.48% Cu, 62ppm Mo, 1.7g/t Ag from 44m, confirming a significant extension of shallow Cu-Mo mineralization to the northwest continuous on section with hole CDH006. Additional step-out drillholes CDH008 (completed) and CDH009 (in progress) have been drilled from the same pad to test extensions to mineralization in north and northwest orientations respectively, with assays pending for both holes.
The ongoing program of scout drilling continues to rapidly expand the mineralized footprint at Cobrasco Central, with every drillhole completed to date reporting significant porphyry Cu-Mo mineralized intercepts from surface or near-surface to depths of approximately 600m. Drillholes completed to date demonstrate a potentially world-class copper porphyry complex, comprising multiple intrusive phases, subvolcanic flow-domes and mineralization events occurring at or near surface.
The current drillhole defined Cu-Mo mineralized footprint now measures approximately 1,000m x 500m, remains open in all directions and is expected to expand further with results from CDH008 and CDH009. High-grade intervals reported to date will be targeted with a second drill rig.
Andina Copper’s President and CEO Joseph van den Elsen commented: “We continue to rapidly advance a wide-spaced scout drilling programme and actively extend the limits of the Cobrasco Central system. Incredibly, after only 7 drillholes the Cu-Mo mineralization footprint already covers an area of 1,000 x 500m, continues to grow with each drillhole and remains open in all directions. Step-out drillholes CDH008 and CDH009 are expected to further extend the drillhole defined mineralization footprint.”
Geology and mineralization details reveal that CDH007 was drilled to a depth of 603m, with mineralization dominated by chalcopyrite hosted within structurally prepared zones. The hole intersected strong argillic alteration in near-surface saprolite, transitioning to phyllic and grey-green sericite alteration in more competent core intervals, with bornite occurring sporadically. The end of the magmatic-hydrothermal brecciation is marked by a faulted contact at 324m, below which grades decrease significantly.
