Andina Copper Corporation has reported highly encouraging assay results from drillhole CDH006 at its Cobrasco Project in Chocó, Colombia, confirming the northwest extension of the mineralized system. The results show 486 meters at 0.42% copper, 51 parts per million molybdenum, and 1.20 grams per ton silver, including a standout interval of 232 meters at 0.68% copper and 75 parts per million molybdenum from 38 meters depth.
The drillhole was collared approximately 400 meters northwest of previous drill pads, representing a significant step-out that successfully tested the northwest extension of the Cobrasco Central mineralization system. Two additional holes, CDH007 and CDH008, have been completed from the same drill platform testing northeast and north orientations, with visible mineralization observed and assay results pending. The ongoing drilling program has expanded the known mineralization footprint to cover a lateral extent of approximately 950 by 525 meters within the upper 600 meters, with the system remaining open in all directions.
President and CEO Joseph van den Elsen noted that every scout drillhole completed to date has intersected significant intervals of copper-molybdenum mineralization, further extending the mineralization footprint. Broadly spaced, systematic scout drilling will continue to define the limits of mineralization, which remains open in all directions, while testing newly developed targets. Preparations are underway for the mobilization of a second drill rig to support both the definition of new mineralized targets and in-fill drilling across the widely spaced scout holes completed to date.
Geological observations from CDH006 reveal important structural controls on mineralization, with a clear association between structural preparation of host units and resulting degrees of alteration and mineralization. The upper approximately 46 meters of drill core show strong weathering characterized by saprolites with oxidation and clay formation, while a low-angle fault structure at this point marks the introduction of high copper and molybdenum grades. At greater depths, lithology transitions to more competent units of rhyolite and rhyodacite with local occurrences of quartz-sulphide veining.
The mineralized system at Cobrasco Central comprises multiple intrusive phases, subvolcanic flow-domes, and mineralization events, demonstrating a significant porphyry complex. The Company’s ongoing exploration program includes a new program of surface mapping and geochemical sampling to run concurrently with drilling, intended to delineate multiple targets for follow-up sampling and drilling.
