Executive Summary

  • Andina Copper reports a significant copper‑gold‑silver intercept from drill hole PIU09 at Piuquenes East, expanding the vertical extent of the mineralized envelope.
  • Hole PIU09 intersected 126 m @ 0.46% Cu, 0.53 g/t Au, 2.14 g/t Ag (from 529 m) within a broader 402 m zone @ 0.25% Cu, 0.21 g/t Au, 1.19 g/t Ag (from 253 m).
  • Follow‑up drilling is underway on PIU11 (Piuquenes East) and a second rig has started testing a deep MT anomaly at Piuquenes North (PIU12), indicating continued exploration momentum.

Key Details

  • Hole PIU09 Intercepts
  • 126 m @ 0.46% Cu, 0.53 g/t Au, 2.14 g/t Ag from 529 m depth.

  • Within 402 m @ 0.25% Cu, 0.21 g/t Au, 1.19 g/t Ag from 253 m depth.

  • Geological Observations

  • Strongly veined dioritic porphyry with intense sericitic overprint on potassic alteration.
  • Development of A‑type veins coincident with chalcopyrite ± bornite mineralization.

  • Higher gold grades and increased veining intensity at depth, suggesting proximity to the porphyry core.

  • Follow‑Up Drilling

  • PIU11 planned to test northern continuity of the Cu–Au‑Ag system using IP and MT chargeability anomalies.

  • Designed to evaluate competing structural models and maximize chance of intersecting deeper mineralization.

  • Second Rig – Piuquenes North

  • Rig mobilized for hole PIU12 targeting a strong, low‑resistivity MT anomaly beginning ~600 m below surface and extending well below current drilling depths.

  • Anomaly interpreted as deep intrusive/magmatic‑hydrothermal source potentially feeding the known porphyry systems to the east and central zones.

  • Previous Results for Context

  • Hole PIU06 (reported 30 Apr 2025) intersected 208 m @ 0.31% Cu, 0.13 g/t Au, 1.24 g/t Ag from 292 m depth, including a higher‑grade sub‑interval of 98 m @ 0.49% Cu, 0.16 g/t Au, 1.26 g/t Ag.

  • QA/QC Procedures

  • Core logged, photographed, and sampled at field camp; samples processed by ALS Minerals (Mendoza) and analyzed in Lima.

  • Certified reference materials, blanks, and duplicates inserted throughout the analytical stream; results deemed reliable.

  • Qualified Person

  • Gustavo Zulliger, CP‑AIPG CPG‑11165, reviewed and approved all technical information per NI 43‑101.

Notable Quotes

  • “The deeper mineralized interval remains open and is chalcopyrite‑dominant with minor bornite, suggesting the potential for continued strengthening of the system at depth.” – Joseph van den Elsen, President & CEO

Materiality Assessment: Material – Positive (the intercepts materially expand the known resource envelope and support ongoing drilling programs).
