Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) announced further outstanding drill intercepts from the Cobrasco Project in Choco, Colombia. Drillhole CDH009, drilled from the same pad as CDH006, CDH007, and CDH008, reached a depth of 954m and confirmed a significant northwesterly extension of near-surface mineralization, with grades notably increasing from 38m downhole.
Highlights include 502 meters grading 0.40% copper, 73 ppm molybdenum, and 1.22 g/t silver from 38 meters downhole, including 388 meters at 0.44% copper, 36 ppm molybdenum, and 1.28 g/t silver, and 186 meters at 0.50% copper, 22 ppm molybdenum, and 1.48 g/t silver. These results expand the drillhole-defined mineralized footprint at Cobrasco Central to approximately 1,200 meters by 550 meters, with the footprint continuing to grow through successive step-out drilling. Mineralization remains open in all directions.
Mineralization persists to the end of CDH009 at 954 meters; however, copper grade decreases at depth as the intensity of overprinting sericite alteration and associated chalcopyrite–bornite mineralization progressively transitions to a lower-grade potassic-altered domain. Two additional drillholes, CDH010 and CDH011, have been completed from the same platform, with assays pending. Wide-spaced scout drilling designed to assess the overall scale potential of the Cobrasco mineralized system is ongoing from a new platform located approximately 350 meters northwest of the previous drill site.
Joseph van den Elsen, Andina Copper President and CEO, stated: “Andina Copper continues to systematically advance its scout drilling programme in a northwesterly direction with wide spaced fans of holes aimed at expanding the envelope of porphyry Cu-Mo mineralization. The results of hole CDH009 validate this approach, significantly extending shallow, near-surface copper-molybdenum mineralization 350m to the northwest. Incredibly, all nine drill holes reported to-date have returned wide intervals of high-grade, near-surface Cu-Mo mineralization. Mobilization of a second diamond drilling rig will expedite continued systematic and aggressive exploration and evaluation of the Cobrasco Central system.”
The geology of CDH009 includes a leached cap with supergene oxidation to 41 meters, below which significant chalcopyrite mineralization occurs as disseminations and veinlets in felsic rhyolite and intermediate daci-andesite porphyries, as well as magmatic-hydrothermal breccias. Below 350 meters, mineralization is associated with halo veins and alteration fronts, with copper grades decreasing but persisting to the end of the hole. For more details, see the original release.
