Copper Giant Delivers Grades Above the 2026 Resource Model and Confirms Porphyry-Style Mineralization at the La Estrella Target

Executive Summary

• Drill holes MD‑053 and MD‑054 at the La Estrella target intercepted copper‑molybdenum mineralization that exceeds the 2026 Mineral Resource Estimate (MRE) block model, confirming porphyry‑style continuity south of the Mocoa deposit.
• Hole MD‑054 returned a high‑grade interval of 61 m grading 0.61 % CuEq (0.41 % Cu, 0.04 % Mo), and a broader 253 m zone at 0.40 % CuEq, both above the modelled waste grades.
• The results support continued resource expansion, validate the 2025 exploration program’s strategic objectives, and set the stage for an expanded 2026 drill campaign focused on conversion and further step‑out drilling.

Key Details

• Hole MD‑053 (La Estrella target)
• Intercepted mineralization from surface to 374 m depth.
• Broad interval (257–374 m, 117 m) grades: 0.05 % Cu, 0.004 % Mo → 0.07 % CuEq.

• Included higher‑grade sub‑interval (203–219 m, 16 m): 0.09 % Cu, 0.002 % Mo → 0.10 % CuEq.

• Hole MD‑054 (south edge of MREA footprint)

• Full‑hole length: 804 m, overall grade 0.13 % Cu, 0.01 % Mo → 0.19 % CuEq.
• Key interval (367–620 m, 253 m): 0.27 % Cu, 0.03 % Mo → 0.40 % CuEq.
• High‑grade sub‑interval (418–478 m, 61 m): 0.41 % Cu, 0.04 % Mo → 0.64 % CuEq.

• Additional high‑grade segment (445–478 m, 33 m): 0.44 % Cu, 0.05 % Mo → 0.70 % CuEq.

• Assay methodology

• Copper equivalent calculated as Cu % + 5.278 × Mo % (using $4.00/lb Cu, $20.00/lb Mo, 90 % Cu recovery, 95 % Mo recovery).

• Grades are uncut; drilled widths interpreted to be close to true widths.

• 2025 Exploration Program Highlights

• Total drilling: ~11,400 m.
• Updated NI 43‑101 Technical Report and MRE filed (Jan 9 2026) – Inferred Resource now 1.12 bn t at 0.51 % CuEq, a 76 % tonnage increase and 101 % contained CuEq increase vs. 2022 estimate.

• Expansion of multiple high‑grade Cu‑Mo domains; demonstrated >1,000 m vertical continuity; system remains open in all directions.

• 2026 Exploration Outlook

• Planned expanded, fully permitted drill program focusing on infill drilling for resource conversion and step‑out drilling toward La Estrella.
• Ongoing de‑risking: environmental baseline work, hydrogeological & geotechnical studies, permitting activities.

Notable Quotes

• “The 2025 program delivered a major milestone… advancing the project beyond the one‑billion‑tonne resource mark… With these results, we close a highly successful exploration year and enter 2026 with a stronger geological model…” – Edwin Naranjo Sierra, Vice‑President of Exploration.
