Copper Giant Intersects 257 Metres of 0.63% CuEq* (0.47% Cu and 0.03% Mo) in Infill Drilling and Identifies Higher Grades at Depth Along the Southern Margin of Mocoa

Executive Summary

• Copper Giant reported significant copper‑molybdenum intercepts from mother holes MD‑056 and MD‑057 at the Mocoa project, including 257 m @ 0.63% CuEq and a higher‑grade interval of 191 m @ 0.72% CuEq.
• The results extend mineralization into areas previously modeled as waste, supporting expansion of the Mineral Resource Estimate (MRE) footprint along the southern margin and improving confidence for future directional drilling.
• These intercepts reinforce the predictability of the current resource model and underpin the company’s strategy to upgrade inferred resources toward a PEA‑level evaluation.

Key Details

• Hole MD‑056 – 386 m @ 0.39% CuEq (0.20% Cu, 0.04% Mo) starting at 307 m; last 77 m of hole: 0.49% CuEq (0.33% Cu, 0.03% Mo).
• Hole MD‑057 – 257 m @ 0.63% CuEq (0.47% Cu, 0.03% Mo) starting at 275 m; includes a 191 m interval @ 0.72% CuEq (0.54% Cu, 0.034% Mo) from 341 m and a broader 476 m interval @ 0.43% CuEq* (0.28% Cu, 0.029% Mo) starting at 56 m.
• Both holes are the first “mother holes” drilled at Mocoa, establishing platforms for future directional daughter‑hole programs that will increase drill efficiency and reduce surface disturbance.
• Intersections occur within zones previously classified as waste in the MRE block model, indicating under‑drilled potential along the southern edge toward the La Estrella target.
• The drilling program continues with two rigs operating at full capacity on site.
