Executive Summary

  • Copper Giant Resources Corp. has filed an independent technical report containing an updated Mineral Resource Estimate (MRE) for its flagship Mocoa copper-molybdenum project in Putumayo, Colombia.
  • The updated MRE represents a significant expansion in scale and grade compared to previous estimates, driven by a 76% increase in tonnage and a 101% increase in contained copper equivalent metal.
  • The resource is defined as Inferred, constrained within a conservative pit shell, and remains open laterally and at depth with multiple untested porphyry targets.

Key Details

  • Updated Mineral Resource Estimate (Effective Dec. 23, 2025):
    • Total CuEq: 12.7 billion pounds (Blb) copper equivalent.
    • Average Grade: 0.51% CuEq.
    • Contained Copper: 7.6–7.7 Blb at 0.31% Cu.
    • Contained Molybdenum: 1.0 Blb at 0.039% Mo.
    • Tonnage: 1.12 billion tonnes (1,120 million tonnes).
  • Comparison to Previous MRE:
    • Tonnage increased by over 76%.
    • CuEq grade increased by over 14%.
    • Contained CuEq metal increased by over 101%.
  • Technical Parameters:
    • Resource Category: Inferred.
    • Pit Shell: Constrained within a conservative revenue factor of 0.65.
    • Commodity Prices Used: $4.0/lb Copper and $20.0/lb Molybdenum.
    • Cut-off Grade: 0.25% CuEq.
  • Geological Context:
    • The system is open laterally and at depth.
    • Multiple untested nearby porphyry targets exist.
    • The deposit exhibits classic porphyry-style zonation with a potassic core, sericite, and propylitic alteration.
    • The system shows over 1,000 metres of vertical continuity and is interpreted as a district-scale mineralized system.
  • Qualified Persons:
    • Michael B. Dufresne, Warren E. Black, and Kevin S. Hon (APEX Geoscience).
    • Chester de Leon (Consultec Ltd.).
    • Edwin Naranjo Sierra (VP of Exploration, Copper Giant) is the designated qualified person who reviewed and approved the information.
  • QA/QC Protocols:
    • Core sampling followed industry best practices with HQ and NQ diameters.
    • Samples analyzed at ActLabs (Medellin and Guadalajara) using four-acid digest AA and ICP-MS.
    • No material QA/QC issues identified regarding sample collection, security, or assaying.

Notable Quotes

  • No direct quotes from the CEO or President were included in the provided text.
