Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has announced outstanding drill results from its Cobrasco Project in Choco, Colombia, further confirming the northwest extension of the Cobrasco Central Cu-Mo porphyry system. Drillhole CDH008 returned 272 meters grading 0.50% copper, 75ppm molybdenum, and 1.92g/t silver from 52 meters downhole, including a higher-grade interval of 152 meters at 0.67% copper, 68ppm molybdenum, and 1.90g/t silver from 54 meters. The results highlight the potential for a large, near-surface mineralized system that remains open in all directions.
The Cobrasco mineralized footprint now extends approximately 1,100 meters along strike and 550 meters laterally, with ongoing drilling expected to expand these dimensions. Two additional step-out holes, CDH009 (completed) and CDH010 (in progress), are testing northwest and west-southwest extensions from the same drill pad, with assays pending. Visual logging indicates sulphide mineralization consistent with the broader Cobrasco Central system in both holes. The company plans to mobilize a second diamond drilling rig for the next phase of definition drilling and testing of new porphyry centers.
This news is significant because it demonstrates the continued growth of the Cobrasco system, a critical factor for investors assessing the project's potential scale. Near-surface mineralization reduces initial mining costs and enhances economic viability. The announcement also underscores the strategic importance of the Andean porphyry belt, which hosts some of the world's largest copper deposits. For Andina Copper, these results could increase the project's attractiveness for future development or partnerships, impacting the company's valuation and the broader copper exploration sector in Colombia.
CDH008 was drilled due north to test the northern continuity of the shallow mineralized zone, intersecting a leached cap with intense supergene alteration over intermineral rhyolite porphyry. Below the leached zone, a 30-meter interval containing chalcocite coating hypogene sulphides suggests incipient secondary copper enrichment. The strongest mineralization is associated with potassic and sericite-altered magmatic-hydrothermal breccias, where chalcopyrite occurs as matrix infill and cross-cutting veinlets. Bornite was locally observed, indicating a possible later higher-sulphidation event. The company's President and CEO Joseph van den Elsen stated, "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 implications for the industry are substantial. Colombia is emerging as a significant jurisdiction for copper exploration, and positive results from Cobrasco could attract more investment to the region. For the reader, this story matters because copper is essential for electrification and green technologies, and new discoveries help meet growing demand. The expansion of mineralization also suggests the project could become a long-term supplier, impacting global copper supply chains.

Drillhole CDH008 was collared with PQ size to 126m and continued with HQ/HQ3 to a final depth of 652.25m. All sampling followed strict QAQC protocols, with core cut by diamond saw and sent to ALS Laboratories in Medellin and Lima for analysis. The qualified person for the news release is Francisco Montes, a consultant of Andina Copper and a member of the Australian Institute of Geoscientists. The company holds two significant discoveries along the Andean porphyry belt in Argentina and Colombia, and a copper-gold target in Chile.
