Andina Copper Reports Major Copper-Molybdenum Intercept at Cobrasco Project, Expanding Known Mineralization
Andina Copper's drillhole CDH008 at the Cobrasco Project in Colombia returned 272 meters of 0.50% copper, confirming northwest extension of the porphyry system, which remains open in all directions.
Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has reported outstanding drill results from its Cobrasco Project in Choco, Colombia, with hole CDH008 intersecting near-surface porphyry copper-molybdenum mineralization extending the known system to the north. The company announced that drillhole CDH008, completed to a depth of 652.25 meters, returned 272 meters at 0.50% copper, 75 ppm molybdenum, and 1.92 g/t silver from 52 meters downhole, including a higher-grade interval of 152 meters at 0.67% copper, 68 ppm molybdenum, and 1.90 g/t silver from 54 meters.
The results confirm the northwest extension of the Cobrasco Central Cu-Mo system, which now extends approximately 1,100 meters along strike and 550 meters laterally. Mineralization remains open in all directions, with further expansion potential toward the northwest and west-southwest pending assays from two additional drillholes, CDH009 (completed) and CDH010 (in progress). Surface geochemistry and field observations strongly suggest that mineralization continues to the north and northwest.
“We continue to systematically advance a wide-spaced scout drilling programme, actively testing the limits of the Cobrasco system with wide fans of significant step-out drillholes,” said Joseph van den Elsen, President and CEO of Andina Copper. “The system continues to grow with each successive drillhole, with the mineralization footprint already covering an area of ~1,100m x 550m, and results from CDH009 and CDH010 expected to further extend.”
Drillhole CDH008 was collared from the same pad as previous holes CDH006 and CDH007 and drilled due north at an inclination of -50° to test the northern continuity of shallow mineralization. The hole intersected a leached cap with supergene alteration over intermineral rhyolite porphyry, followed by a 30-meter interval of chalcocite coating hypogene sulphides, indicating incipient secondary copper enrichment. The strongest mineralization is associated with potassic and sericite-altered magmatic-hydrothermal breccias, where chalcopyrite occurs as matrix infill and veinlets. Bornite was locally observed, suggesting a later higher-sulphidation event.
The company is preparing to mobilize a second diamond drilling rig to support the next phase of definition drilling at Cobrasco Central and to test new porphyry centers. Andina Copper’s corporate presentation is available at Andina Copper Corporate Presentation.
