Cobrasco Cu-Mo Project Three Diamond Drill Holes Completed

VANCOUVER – Andina Copper Corporation reported on the maiden diamond drillhole CDH003 at the Cobrasco copper-molybdenum project located in the Chocó Department, Colombia. Since commencing field exploration in early October 2025, the Company has completed a total of three diamond drill holes for 2609 m, with a fourth hole currently underway.
CDH003 intersected significant copper mineralization from surface to final depth (774.8m). High-grade intersections include: 1) 352 m @ 0.68% Cu, 112 ppm Mo, 1.55 g/t Ag from 144 m, including 118 m @ 1.17% Cu, 193 ppm Mo, 2.35 g/t Ag from 246 m. 2) Drilling continues at Cobrasco, with 3 holes completed to date for 2609 m. 3) CDH004 and CDH005 were completed to depths of 900 m and 934 m respectively, with assay results for CDH004 expected shortly. 4) Drill rig mobilized to a platform ~410 m NW of CDH005 and 390 m SW of CDH001. 
Surface reconnaissance along the northern extensions of the mineralized trend has confirmed outcrops of early-stage A-type stockwork veining and limonites after sulphides, over 1km from the area currently being drilled. Sporadic gold mineralization reported in CDH003, suggestive of a possible gold rich intrusive phase within the broader Cobrasco system. 
President and CEO, Joseph van den Elsen, said, “These exceptional assay results from our very first drillhole validate Cobrasco as a globally significant Cu-Mo porphyry system and clearly demonstrate potential for large tonnages of high-grade mineralization. Ongoing drilling is expected to further expand the multi-kilometer footprint of mineralization both northward and south along the well-defined structural corridor.
2026 promises to be an exciting time for Andina Copper shareholders, as we are now in a catalyst rich period with strong, exploration driven news flow being generated across all three of our projects. The 2025-26 field season is well underway at Piuquenes and exploration is continuing at pace at Cobrasco, with results from CDH004 expected shortly. Follow-up exploration will also shortly commence at Mantau.”
