Copper Giant completes first drill hole at East Valley

Executive Summary

• Copper Giant completed its first drill hole (MD‑048) at the newly tested East Valley target, intersecting porphyry‑style mineralization with copper, molybdenum, zinc and lead sulfides.
• The 785.3 m hole confirms a multi‑phase intrusive system and provides clear structural vectors suggesting a feeder zone east of the hole, guiding the next phase of step‑out drilling.
• Results expand the known mineralized envelope well beyond the current Mocoa resource footprint, indicating district‑scale potential for additional copper‑molybdenum (and polymetallic) resources.

Key Details

• Hole MD‑048: Depth 785.3 m; first drill test at East Valley, located west‑northwest of the existing Mocoa resource.
• Mineralization intersected:
• Upper interval – sericite‑altered dacite porphyry with disseminated pyrite, iron oxides, D‑type veinlets (leach cap analogue).
• Mid‑depth – chlorite‑sericite alteration hosting C‑ and D‑type veinlets, microdiorite (E0‑type) and microtonalite porphyries with sulfide mineralization dominated by pyrite, minor chalcopyrite and galena.
• Lower interval – brecciated tuff and altered porphyry containing sphalerite, galena, chalcopyrite, pyrite.
• Vector evidence:
• Molybdenite veinlets trend W‑NW; polymetallic quartz‑carbonate (sphalerite‑pyrite‑galena) veinlets trend N‑NE. Both sets dip eastward away from the core Mocoa deposit, implying a feeder zone east of MD‑048.
• Additional intrusive phase: Low‑grade, late‑stage porphyry with magnetite, pyrrhotite, hornblende, pyrite and chalcopyrite, interpreted as oxidized, hydrous magma contribution to prolonged hydrothermal activity.
• Planned follow‑up: Systematic step‑out drilling and expanded soil geochemistry targeting the inferred feeder zone and extending vectors eastward.
• Qualified Person: Edwin Naranjo Sierra, VP Exploration (NI 43‑101 qualified). No material QA/QC issues identified.

“This first hole at East Valley has given us a much clearer understanding of its geology and the direction mineralization may extend… With these results, we now have clear vectors for the next stage of exploration.” – Edwin Naranjo Sierra, Vice‑President Exploration

Materiality Assessment: Material – Positive (the drill result materially expands the known mineralized system beyond the current resource, indicating significant upside potential).
