COPPER GIANT OUTLINES EXPANSION UPSIDE WITH A 977 TO 1,247 MILLION TONNE CONCEPTUAL EXPLORATION TARGET RANGING 0.49 - 0.55% COPPER EQUIVALENT (0.31 - 0.36% CU AND 0.035 - 0.039% MO) AT THE MOCOA DEPOSIT
Working with APEX, Copper Giant has outlined a conceptual Exploration Target for material lying outside the Current (2021) Mineral Resource Estimate1; highlights include:
- Target size: 977 – 1,247 million tonnes
- Target grade: 0.49 – 0.55 CuEq (0.31 – 0.36% Cu and 0.035 – 0.039% Mo)
- The Exploration Target is based on all drilling to date at the project and is exclusive of, and represents the exploration upside of, the area surrounding and outside of the Current (2021) Mineral Resource Estimate.
The quantity and grade of the Exploration Target mineralized material are conceptual in nature, as there has not been sufficient exploration and drilling to define a mineral resource, and it is uncertain whether exploration will result in the target being delineated as a mineral resource. The defined Exploration Target should not be misrepresented or misconstrued as an estimate of a mineral resource or mineral reserve. The Exploration Target Model has not been evaluated for reasonable prospects of eventual economic extraction (RPEEE).
In accordance with the requirements of National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), Copper Giant has established the Exploration Target for the

The potential quantity and grade of the Exploration Target is conceptual in nature, and there has not been sufficient exploration and drilling to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource. The Exploration Target Model has not been evaluated for RPEEE. *Copper equivalent (CuEq) for the Exploration Target is calculated as: CuEq (%) = Cu (%) + 5.0 × Mo (%), utilizing metal prices of Cu -
The Exploration Target used a modern 3D-geological model provided by Company geologists for the
The Exploration Target was developed using both copper and molybdenum assay results from previous and Copper Giant's most recent drilling. Mineralization trends were evaluated visually to generate a trend model, which informed the construction of grade shells. These grade shells were used to estimate the distribution of mineralized tonnes and grade to support the generation of grade-tonnage curves. The Exploration Target will be utilized to guide future drilling in these areas of known mineralization.
Over the Exploration Target there are a total of 31 drillholes (Ingeominas-United Nations) yielding a total of 18,307 meters, and 15 modern (B2gold and Copper Giant) drillholes yielding a total of 11,441 meters in the drillhole database. The drillhole database contains a total of 17,040 sample interval entries. A total of 5,626 sample intervals are contained within the mineralization domains utilized for the Exploration Target
New Geological Interpretation Highlights Mocoa's District-Scale Potential
Over the past six months, Copper Giant's technical team has completed a comprehensive re-interpretation of the robust geological, geochemical, and geophysical datasets from the
-
Tectonic setting – Mocoa lies in the Andean cordillera, a prime jurisdiction for large tier-one porphyry deposits. Mocoa is part of the Jurassic porphyry belt of the Andean magmatic arc, part of the same compressional belt that hosts Mirador*, Warintza*, San Carlos*, and Panantza*, all located in
Ecuador . - Extended fertile period* – U-Pb zircon and Re-Os molybdenite geochronology reveal a prolonged magmatic-hydrothermal window of approximately 10 million years (182–172 Ma), allowing sustained metal circulation and overprinting.
- Multiphase intrusions – The presence of early-, inter-, and late-mineral porphyries, as well as mineralized breccias, reflects a dynamic, long-lived system with repeated episodes of metal input and fluid flow.
- Fertile magma chemistry – Whole-rock geochemistry confirms a calc-alkaline, hydrous, and oxidized magma source with elevated Sr/Y ratios, typical of fertile porphyry systems.
-
Large alteration footprint – Surface mapping and magnetic data (refer to news release dated
May 3, 2022 ) define a 6 × 5 km demagnetized zone (~30 km²) with classic concentric potassic, phyllic, and propylitic zonation based on the alteration modelling. - High stockwork density and metal zoning – Core logging reveals ≥3% quartz-vein stockwork densities related to the high-grade zones. Modelled geochemical patterns show molybdenum enrichment near surface and lung-shaped surrounding the high-grade copper shell.
-
Volume, vertical extent, and openness – Based on recent drilling, the Mocoa porphyry system has been defined over a strike length of approximately 2.5 kilometres, with a width of 1.0 kilometre and vertical continuity exceeding 1.0 kilometre. In addition, integrated interpretation of geophysical surveys (refer to news release dated
May 3, 2022 ) and follow-up fieldwork (refer to news releases datedNovember 15, 2022 ;February 7, 2023 ;January 27, 2025 ) has outlined at least nine additional porphyry targets across the broader project area, underscoring the district-scale potential beyond the main Mocoa deposit.
*The Fertile Period represents the duration of magmatic-hydrothermal activity associated with copper mineralization, based on radiometric dating methods such as U-Pb, Re-Os, and K-Ar for the Mocoa project. Mirador, Warintza, San Carlos and Panantza are independent of Copper Giant and are no guarantee of the future performance of Copper Giant projects and no inference can be made of mineral resources or reserves from adjacent deposits.

- In–pit resources are contained within an optimized shell generated using
US$3.00 /lb Cu andUS$10.00 /lb Mo; CuEq %= Cu % + 3.33 × Mo %. - Base–case cut–off grade: 0.25 % CuEq.
- Metal recoveries applied: 90 % Cu, 75 % Mo (preliminary historical internal metallurgical testing).
- Optimized–pit parameters: Cu US$3.00/lb, Mo US$10.00/lb, 45° slope, mining cost
US$2.50 /t, G&AUS$2.00 /t, processing costUS$10.00 /t. - Effective date: 1 November 2021.
- Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
- Cautionary note: a Regional Forest Reserve formerly overlapped the western part of the deposit, limiting the pit to 325 Mt at 0.46 % CuEq. Subsequent boundary updates confirmed no overlap between the Reserve and the known Mocoa resource (refer to Copper Giant's news release dated
November 12, 2024 ).

About the Mocoa Porphyry System
The Mocoa project is located in the department of Putumayo, approximately 10 kilometres from the town of Mocoa in southern
Discovered in 1973 through a regional geochemical survey by the
The deposit is hosted in Middle Jurassic dacite and quartz-diorite porphyries intruding andesitic to dacitic volcanics, within
The system features over 1,000 metres of vertical continuity, overlapping hydrothermal stages, and a broad alteration footprint. Multiple intrusive phases, brecciation events, and vein generations suggest a dynamic magmatic-hydrothermal evolution likely driven by more than one porphyry center.
Mocoa remains open in all directions, with several satellite targets identified across the broader land package. These features support the interpretation of a district-scale porphyry system and position Mocoa as one of the most significant undeveloped copper-molybdenum assets in the Andes.
