Copper Giant Confirms Third Mineralized Breccia Corridor at Mocoa, Extends System Below Conceptual Pit

The new findings expand the copper resources to be extracted by the company

Copper Giant Resources Corp. (TSXV: CGNT | OTCQB: LBCMF | FRA: 29H0) has released assay results from two drill holes at its Mocoa copper-molybdenum porphyry project in Putumayo, Colombia, extending mineralization below the current conceptual pit and confirming a third mineralized breccia corridor at the deposit.

Deep infill hole MD-064 intersected 1,052 meters of continuous mineralization from 155 meters downhole, including 486 meters grading 0.57% copper equivalent (CuEq) — 0.41% Cu and 0.029% Mo — which exceeds the deposit’s current mineral resource estimate (MRE) average of 0.51% CuEq. A higher-grade core of 115 meters returned 0.65% CuEq (0.34% Cu and 0.058% Mo) from 552 meters. The final 180 meters of the hole intersected the western breccia, returning 0.44% CuEq (0.36% Cu and 0.015% Mo), including 72 meters of 0.55% CuEq (0.51% Cu and 0.008% Mo).

Results to date continue to demonstrate Cu and Mo mineralization below the current conceptual pit design and within areas previously modeled as waste, supporting the potential for resource expansion along the southern margin of the system toward the La Estrella corridor.

Further Expansion of Directional Drilling

The western breccia intersection provides the first modern drill confirmation of a corridor identified only historically, establishing Mocoa as a system with three drill-tested mineralized breccia corridors — western, central, and eastern — consistent with a large, multi-phase porphyry deposit with multiple mineralized centers.

Directional daughter hole MD-063, drilled from the platform of mother hole MD-056, targeted the southern expansion of the deposit below the current conceptual pit. It returned 808 meters of continuous mineralization from its kick-off point, including 303 meters grading 0.41% CuEq (0.25% Cu and 0.031% Mo) from 541 meters downhole — ground the company had previously modeled as waste. The result extends known mineralization at depth and to the south toward the La Estrella target area, where Copper Giant’s third drill rig is currently conducting maiden drilling from the other direction.

Copper Giant uses directional drilling to test multiple targets from a single pad without constructing new roads or platforms in Mocoa’s steep terrain, which reduces surface disturbance and cost per meter of geological information. MD-063 follows a series of holes — MD-054, MD-056, MD-058, and MD-061 — that have progressively identified stronger mineralization along the southern margin of the current MRE footprint. The area was historically tested only by shallow and sub-vertical drilling.

“These two holes do something more valuable than chasing a high number. MD-064 confirms the continuity and grade of the deposit across more than a kilometre of core, which leads us to believe the resource model we will build the PEA on is sound. MD-063 shows the system continuing below the current pit, in ground we had modelled as waste, and the first modern confirmation of the western breccia tells us Mocoa is a larger, multi-center system than the current resource captures. We are increasing confidence in what we have and adding to what is still to come, exactly what we want heading into the PEA,” said Edwin Naranjo Sierra, Vice-President of Exploration.

More Testing Planned for the Future

The Mocoa project hosts a 1.12-billion-tonne Inferred resource containing 12.7 billion pounds of CuEq — 7.7 billion pounds of copper at 0.31% Cu and 1.0 billion pounds of molybdenum at 0.039% Mo — with an effective date of November 18, 2025. Upcoming catalysts include an updated MRE, a second stage of metallurgical testing, the planned preliminary economic assessment (PEA), and assay results from the La Estrella maiden drilling program. Earlier metallurgical tests at Mocoa returned copper recoveries of up to 92.3% and molybdenum recoveries of up to 97.4%, exceeding the recovery assumptions used in the current resource model.

Drilling is advancing toward the emerging Mocoa–La Estrella corridor from both directions, while MD-064 validates higher-grade domains within the MRE footprint.

The Mocoa project is located approximately 10 kilometers from the town of Mocoa in southern Colombia’s Department of Putumayo. Copper Giant controls more than 128,300 hectares of district-scale tenure through granted titles and applications across a portion of the Jurassic porphyry belt in the northern Andes. The deposit was first identified in 1973 through a regional geochemical survey conducted by the United Nations and the Colombian government, with follow-up drilling by B2Gold (NYSE American: BTG; TSX: BTO) in 2008 and 2012. In 2025, Copper Giant finalized a prior consultation agreement with the Inga Condagua Indigenous Nation, a prerequisite for advancing exploration permitting.

Edwin Naranjo Sierra, VP of Exploration, is the NI 43-101 Qualified Person who reviewed and approved the technical disclosure. Assay samples were prepared at the ActLabs certified facility in Medellín and analyzed for a full multi-element suite at ActLabs’ certified laboratory in Guadalajara, Mexico. Copper equivalent values are calculated using copper at $4.00 USD/lb and molybdenum at $20.00 USD/lb, with metallurgical recoveries of 90% for copper and 95% for molybdenum.
