Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has announced further outstanding drill intercepts from the Cobrasco Project in Choco, Colombia, confirming a significant northwesterly extension of near-surface mineralization. Drillhole CDH009, drilled to a final depth of 954 meters from the same pad as previous holes, returned 502 meters at 0.40% copper, 73 ppm molybdenum, and 1.22 g/t silver from 38 meters downhole, including 388 meters at 0.44% copper and 186 meters at 0.50% copper. These results expand the drillhole-defined mineralized footprint at Cobrasco Central to approximately 1,200 meters by 550 meters, with mineralization remaining open in all directions.
The hole intersected a leached cap with supergene oxidation to about 41 meters, below which significant chalcopyrite mineralization occurs as disseminations and veinlets in rhyolite and daci-andesite porphyries, as well as magmatic-hydrothermal breccias. Copper grades are highest in the upper 300 meters, associated with intensive sericite alteration. At depth, the system transitions to a lower-grade potassic-altered domain, but mineralization persists to the end of the hole at 954 meters. Two additional step-out drillholes, CDH010 and CDH011, have been completed from the same platform, with assays pending. Wide-spaced scout drilling is ongoing from a new platform 350 meters northwest to assess the overall scale potential.
Joseph van den Elsen, 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.”
