Andina Copper Intersects 352 m @ 0.68% Cu, 112 ppm Mo from 144 m, incl. 118 m @ 1.17% Cu, 193 ppm Mo from 246 m

Executive Summary

• Andina Copper released assay results for maiden drillhole CDH003, revealing a 352 m interval with 0.68% Cu, 112 ppm Mo and 1.55 g/t Ag from 144 m depth, including a higher‑grade 118 m sub‑interval of 1.17% Cu, 193 ppm Mo and 2.35 g/t Ag.
• The hole intersected continuous copper mineralization from surface to the final depth of 774.8 m, confirming Cobrasco as a large‑scale Cu‑Mo porphyry system with potential for high‑tonnage, high‑grade resources.
• Ongoing drilling program: CDH004 and CDH005 completed (900 m & 934 m) – results pending; CDH006 mobilized for NW step‑outs; surface reconnaissance identified additional mineralized outcrops >1 km from current drill area.

Key Details

• Total drilling to date: 3 holes, 2,609 m completed; a fourth hole underway.
• CDH003 intercepts (significant):
• 352 m @ 0.68% Cu, 112 ppm Mo, 1.55 g/t Ag from 144 m depth.
• Included 118 m @ 1.17% Cu, 193 ppm Mo, 2.35 g/t Ag from 246 m depth.
• Overall mineralization: Continuous Cu from surface to 774.8 m; unconstrained interval of ~0.37% Cu (0.44% CuEq) over the full length.
• Additional drill holes:
• CDH004 – depth 900 m, assays pending.
• CDH005 – depth 934 m, samples being dispatched to ALS laboratory.
• CDH006 – mobilized; planned NW step‑outs (>500 m) to expand lateral footprint.
• Surface work: Reconnaissance identified A‑type stockwork veining and limonites >1 km north of current drilling; sporadic gold mineralization noted in CDH003, suggesting a possible Au‑rich intrusive phase.
• Geology summary: Multiple porphyry intrusions (intermediate to felsic) with strong potassic alteration, brecciation, and Cu‑bearing veinlets (chalcopyrite, bornite). Presence of La Equis Formation andesite host sequence at ~640 m depth.
• QA/QC: Qualified Person Francisco Montes (MAIG #4160) verified technical information; samples processed by ALS labs in Medellín (pre‑prep) and Lima (analysis); no QA/QC issues identified.
• CEO comment: “These exceptional assay results … validate Cobrasco as a globally significant Cu‑Mo porphyry system… 2026 promises to be an exciting time for Andina Copper shareholders…”

Notable Quotes

“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.” – Joseph van den Elsen, President & CEO

Materiality Assessment: Material – Positive (significant new drilling data indicating a potentially large, high‑grade copper‑molybdenum resource.)
