Andina Copper Reports Near-Surface Porphyry Copper-Molybdenum Mineralization at Cobrasco Project

Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) reported continuing outstanding drill intercepts from the Cobrasco Project in Choco, Colombia. Drillhole CDH008, completed to a depth of 652.25m, extended the Cobrasco Central Cu-Mo porphyry system to the north, with near-surface mineralization beginning at approximately 52m downhole. The hole returned 272m @ 0.50% Cu, 75ppm Mo, and 1.92g/t Ag from 52m, including 152m @ 0.67% Cu, 68ppm Mo, and 1.90g/t Ag from 54m.

The mineralization is associated with multiple mineralized porphyry phases and related magmatic-hydrothermal breccias. CDH008 was drilled due north to test the northern continuity of the shallow mineralized zone. Two additional drillholes, CDH009 (completed, assays pending) and CDH010 (in progress), have been completed from the same platform, testing northwest and west-southwest extensions, respectively. Visual logging indicates sulphide mineralization consistent with the broader Cobrasco Central system.

The Cobrasco mineralized footprint now extends approximately 1,100m along strike and 550m laterally, remaining open in all directions. Further expansion potential toward the NW and WSW is imminent pending results from CDH009 and CDH010. Ongoing scout drilling continues, with large step-out holes targeting the NW and northern extensions planned.

Andina Copper’s President and CEO Joseph van den Elsen commented: “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. 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. Surface geochemistry and field observations strongly suggest that the mineralization continues to the north and northwest and indeed remains open in all directions.”

Geology and mineralization details for CDH008 indicate a leached cap with intense supergene alteration over intermineral rhyolite porphyry. Beneath the supergene-leached zone, a 30m interval containing chalcocite coating hypogene sulphides suggests incipient secondary copper enrichment. The upper portion comprises sericite-altered intermineral rhyolite porphyry intruding dacite-andesite porphyry, with early quartz veins containing disseminated chalcopyrite and pyrite. The strongest mineralization is associated with potassic and sericite-altered magmatic-hydrothermal breccias related to intermineral rhyolite porphyry intrusions, where chalcopyrite occurs as matrix infill and cross-cutting veinlets overprinting molybdenite. Bornite was locally observed, possibly indicating a later higher-sulphidation event.
