Andina Copper Reports 620 m @ 0.45% Cu, 79 ppm Mo from 62 m, including 146 m @ 0.76% Cu, 107 ppm Mo

Executive Summary

• Andina Copper reported significant wide copper‑molybdenum intercepts from drillhole CDH004 at the Cobrasco project, confirming high‑grade mineralization previously seen in CDH003.
• Sporadic gold up to 1.06 g/t was intersected in CDH004, suggesting a gold‑rich intrusive phase within the system.
• Additional drilling (CDH005, CDH006) is underway to expand the footprint and test southern extensions; assays for CDH005 are pending.

Key Details

• CDH004 results:
• Hole depth = 900.25 m.
• Interval 579–686 m: average 0.75 % Cu, peak 1.70 % Cu over a 2‑m sample.
• Overall copper grade cut‑off applied at 0.2 % Cu; maximum dilution 20 m.
• Gold mineralization up to 1.06 g/t observed sporadically.
• Geological observations (CDH004):
• Upper 56 m: intermediate porphyries with up to 0.39 % Cu and 393 ppm Ag.
• 56–579 m: felsic rhyolite/rhyodacite/dacite sequences intersected by mineralized porphyry intrusions.
• 686–900 m: phreatomagmatic breccias with low copper (average 215 ppm Cu, max 0.20 % Cu).
• CDH005:
• Collared from same pad as CDH002‑CDH004; azimuth 180°, dip –50°.
• Designed to test southern extension; completed to 934 m (assays pending).
• Intersects magnetic intrusive sequences, felsic intrusives with chalcopyrite‑dominant sulphides and sericitic alteration.
• CDH006: Step‑out hole currently drilling to evaluate large extensions of the mineralized system.
• Future plans: Mobilization of a second drill rig announced to accelerate exploration; step‑out drilling will target footprint expansion, volume addition to copper grade shells, and lateral extent definition.

Notable Quotes

“Following recent results from CDH003, the wide intercepts of high‑grade copper mineralization reported in CDH004 further validate the size, scale and grade of the Cobrasco system… Ongoing step‑out drilling will now seek to systematically expand the footprint of the system, add volume to the copper grade shells and define the lateral extents of the system.” – Joseph van den Elsen, President & CEO
