Copper Giant Announces Updated Mocoa Inferred Mineral Resource of 1.1 Billion Tonnes at 0.51% CuEq* (0.31% Cu and 0.039% Mo)

Executive Summary

• Copper Giant announced a 2025 updated NI 43‑101 inferred mineral resource for the 100% owned Mocoa project of 1.12 billion tonnes at 0.51 % CuEq (≈12.7 Blbs CuEq), representing a +76 % increase in tonnage, +14 % higher grade, and +101 % more contained copper‑equivalent metal versus the 2022 estimate.
• The resource now contains 7.6 Blbs of copper (0.31 % Cu) and 1.0 Blb of molybdenum (0.039 % Mo), making Mocoa one of the world’s largest undeveloped copper‑molybdenum systems and a significant source of critical molybdenum.
• Ongoing drilling (9,525 m since 2022) continues to expand high‑grade zones; the system remains open laterally and at depth with additional nearby porphyry targets identified.

Key Details

• Resource Summary (cut‑off 0.25 % CuEq):
• Tonnes: 1,120 Mt
• CuEq grade: 0.51 %
• Copper: 7.6 Blbs at 0.31 % Cu
• Molybdenum: 1.0 Blb at 0.039 % Mo
• Higher Cut‑offs: At a 0.70 % CuEq cut‑off, the resource still contains 190 Mt with 0.94 % CuEq, 0.53 % Cu, and 0.077 % Mo (≈3.9 Blbs CuEq).
• Drilling Impact: 9,525 m of drilling added 671,000 lb of CuEq per metre drilled since the 2022 MRE. Two drill rigs are operating on a 14,000‑m program to further delineate extensions.
• Economic Assumptions Used in Estimate:
• Copper price: US$4.00/lb
• Molybdenum price: US$20.00/lb
• Recoveries: 90 % Cu, 95 % Mo
• Processing cost: US$10/t, G&A US$1/t, royalty 3 % NSR
• Pit Optimization Parameters: Mining cost US$2.5/t (mineralized & waste), 45° slopes, revenue factor 0.65, resulting in a pit‑constrained resource reported at the 0.25 % CuEq cut‑off.
• Quality Assurance/Control: Core sampling HQ/NQ, QA/QC inserts of standards, blanks and duplicates; labs: ActLabs (Medellín) and certified lab in Guadalajara; no material QA/QC issues identified.
• Qualified Persons: Kevin Hon & Warren Black (APEX Geoscience) – independent QPs responsible for the MRE; Edwin Naranjo Sierra (Copper Giant) – company QP reviewing technical information.
• Forward‑Looking Statements: Include expectations on further resource expansion, economic studies, and project advancement; subject to typical exploration, permitting, market, and political risks.

Notable Quotes

“Mocoa has now joined a very small group of near‑surface copper systems worldwide that exceed a billion tonnes — and we're still drilling at the edges… This milestone comes at a time of structural copper deficits and accelerating global demand.” – Ian Harris, President & CEO

“The updated constrained resource model also highlights significant untapped potential: large portions of the optimized shell remain completely undrilled and are currently classified as waste, providing immediate, low‑risk opportunities for ongoing drilling.” – Edwin Naranjo Sierra, Vice‑President of Exploration
