Coppernico Channel Samples 52 m of 1.06% Copper at Sombrero in Peru

Executive Summary

• Coppernico announced initial surface channel sampling results from the Nioc target showing multiple intervals with >1 % Cu and notable Au‑Ag grades, indicating high‑grade copper‑gold skarn mineralization.
• The best composites include 52 m @ 1.06 % Cu, 0.19 g/t Au, 1.20 g/t Ag (Zone 1) and 36 m @ 1.10 % Cu, 0.32 g/t Au, 3.44 g/t Ag (Zone 2).
• The results overlay a large 1.8 km × 1.4 km chargeability anomaly, supporting the potential for deeper sulphide mineralization and guiding future drill targeting once community agreements are secured.

Key Details

• Sampling Overview: First systematic surface channel sampling across two skarn‑altered zones (Zone 1 & Zone 2) on the Nioc target area of the Sombrero copper‑gold project in Peru.
• Zone 1 Highlights:
• 25SRT‑029 – 52 m @ 1.06 % Cu, 0.19 g/t Au, 1.20 g/t Ag
• 25SRT‑030 – 40 m @ 0.96 % Cu, 0.13 g/t Au, 0.96 g/t Ag
• 25SRT‑032 – 93.5 m @ 0.87 % Cu, 0.19 g/t Au, 0.60 g/t Ag
• Zone 2 Highlights:
• 25SRT‑040 – 32 m @ 0.59 % Cu, 0.23 g/t Au, 1.44 g/t Ag
• 25SRT‑042 – 36 m @ 1.10 % Cu, 0.32 g/t Au, 3.44 g/t Ag
• 25SRT‑043 – 26 m @ 0.99 % Cu, 0.40 g/t Au, 3.11 g/t Ag
• Representative Rock Samples:
• Sample G691308 (25STR‑043) – 2.81 % Cu, 1.19 g/t Au, 2.24 g/t Ag (garnet–magnetite skarn).
• Sample Y209449 – 3.10 % Cu, 0.55 g/t Au, 8.70 g/t Ag (magnetite skarn with chalcopyrite).
• Geophysical Context: Channels lie directly over a 1.8 km × 1.4 km chargeability anomaly (>20 mV/V) modeled to at least 500 m depth, suggesting extensive sulphide mineralization at depth.
• True Widths: Not yet determined; composites represent full channel lengths with no exclusions. Minimum reporting length = 6 m; internal dilution ≤ 0.2 % Cu.
• Quality Control: Samples assayed by ALS Lab (fire assay for Au, ICP‑MS/ICP‑AES for multi‑elements). QA/QC includes blanks, duplicates, and standards; results indicate good accuracy and precision.
• Next Steps: Expand surface mapping and channel sampling to refine geometry; commence drilling as soon as community agreement is achieved.
• Investor Outreach: CEO Ivan Bebek will present at multiple conferences (Precious Metals Summit Beaver Creek – Sep 11, 2025; Nordic Funds & Mines – Oct 8‑9, 2025; etc.) and conduct roadshows in North America and Europe to discuss the project pipeline.

Notable Quotes

• Ivan Bebek, Chair & CEO: “Sombrero is unique both in its large scale and grade… these positive results not only significantly benefit our targeting and increase opportunities for discovery…”
• Tim Kingsley, VP Exploration: “These maiden results from Nioc are further validation of the thesis of extensive district‑scale mineralization at Sombrero… Nioc is shaping up to be a major target area alongside the adjacent Ccascabamba target.”
