Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has reported outstanding drill intercepts from the second hole of its maiden diamond drilling program at the Cobrasco copper-molybdenum project in Choco, Colombia. The results from drillhole CDH004 follow recent high-grade intersections in CDH003 and further validate the size and scale of the mineralized system.
Drillhole CDH004, completed to a depth of 900.25 meters, returned wide intercepts of copper-molybdenum mineralization, including a 107-meter interval from 579 to 686 meters averaging 0.75% copper, with a peak 2-meter assay of 1.70% copper. The hole also encountered sporadic gold mineralization up to 1.06 g/t, suggesting a possible gold-rich intrusive phase within the broader Cobrasco system.
According to Joseph van den Elsen, President and CEO of Andina Copper, the results from CDH004 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 and evaluation. Ongoing step-out drilling aims to expand the mineralized footprint and define lateral extents.
The geology of CDH004 includes multiple phases of rhyolite, rhyodacite, and dacite, cut by mineralized intermediate porphyry intrusions. The strongest copper grades are associated with intensely fractured magmatic-hydrothermal breccias, interpreted as a significant contributor to the mineralized system. The hole also intersected late-stage phreatomagmatic breccias with low copper grades, which may represent a boundary lithology for future drilling.
Drillhole CDH005, collared from the same pad and designed to test southern extensions, has been completed to 934 meters. Assays are pending, but visual logging indicates significant chalcopyrite-dominant sulfide mineralization with sericitic alteration, consistent with mineralized porphyry systems elsewhere in the district. The continuity of intrusive phases and alteration supports the interpretation of a large, long-lived mineralizing system extending south of the current drill footprint.
Francisco Montes, a qualified person under NI 43-101, has verified the technical information in this release. The company follows strict QAQC protocols, with samples sent to ALS Laboratories in Medellin and Lima for analysis.
Detailed geological and geotechnical logging is ongoing, and results from CDH005 are expected shortly. Step-out drillhole CDH006 is currently underway, targeting potential large extensions of the mineralized system.
