Copper Giant Announces Filing of Technical Report for the Mocoa Project containing Updated Mineral Resource Estimate
Executive Summary
- Copper Giant filed an NI 43‑101 technical report announcing an updated inferred mineral resource of 12.7 billion lbs CuEq at 0.51% CuEq, representing a +76 % increase in tonnage, +14 % higher grade, and +101 % more contained metal versus the prior estimate.
- The resource comprises 7.6 billion lbs copper (0.31% Cu) and 1.0 billion lbs molybdenum (0.039% Mo) within 1.12 billion tonnes, constrained by a pit‑shell cut‑off of 0.25 % CuEq using $4.00/lb Cu and $20.00/lb Mo pricing.
- The estimate was prepared by independent Qualified Persons from APEX Geoscience; the system remains open laterally and at depth with multiple nearby untested porphyry targets, supporting further upside potential.
Key Details
- Effective date of Technical Report: 23 Dec 2025 (effective 18 Nov 2025).
- Resource classification: Inferred mineral resources only; no reserves disclosed.
- Cut‑off grades & corresponding tonnage/grade/contained metal:

- Economic assumptions used:
- Cu price = US$4.00/lb, Mo price = US$20.00/lb
- Process recoveries: 90 % Cu, 95 % Mo
-
Processing cost = US$10/t, G&A = US$1/t, NSR royalty = 3 %
-
Pit‑shell parameters: US$2.5/t mining cost (mineralized & waste), 45° slopes; pit‑constrained resources reported at 0.25 % CuEq cut‑off.
-
Qualified Persons: Kevin Hon, B.Sc., P.Geo.; Warren Black, M.Sc., P.Geo. (APEX) – independent QPs; peer review by Michael Dufresne, M.Sc., P.Geo., President & CEO of APEX. Edwin Naranjo Sierra, VP Exploration (Copper Giant) acted as company QP for the release.
-
QA/QC: No material QA/QC issues identified; core sampling, assay protocols, and data validation procedures described in detail.
-
Project context: Mocoa lies in Colombia’s Putumayo Dept., covering >132,500 ha of district‑scale tenure within a Jurassic porphyry belt; the system is open in all directions with multiple satellite targets, indicating potential for further resource expansion.
