COPPER GIANT, WORKING WITH THE COLOMBIAN GOVERNMENT, SECURES LONG-TERM DEVELOPMENT FRAMEWORK AT MOCOA; THIRD DRILL RIG NOW OPERATIONAL

Colombia's National Mining Agency (ANM) has approved the integration of mining titles FJT-131 and FJT-141 into a single unified concession at Copper Giant Resources Corp.'s Mocoa copper-molybdenum project, resetting the concession term to a new exploration stage. The integrated title contains no forestry reserve or protected area overlap, and the current mineral resource estimate is fully contained within the concession and unaffected. This follows the clarification of forestry reserve boundaries announced in November, 2024, and reflects the company's continued constructive engagement with Colombian institutions. The company has also completed the mobilization of a third drill rig, as announced on April 8, 2026, bringing the active fleet to three rigs as part of its fully financed 2026 exploration program

• Long-term development framework secured. Integration of mining titles FJT-131 and FJT-141 approved by the ANM, resulting in a single unified concession with the term reset to a new exploration stage, establishing a long-term development runway aligned with the current stage of the project.
• No forestry reserve or protected area overlap. The integrated concession contains no forestry reserve or protected area. The current mineral resource estimate is fully contained within the title, no resource impact.
• Third drill rig operational. Mobilization complete, three rigs now active. Infill drilling for resource conversion and expansion toward La Estrella and Piedralisa running in parallel.

"This secures the long-term framework to develop Mocoa at the scale this system deserves. A clean unified title, no forestry reserve overlap and three rigs now drilling -- we've built the foundation to advance toward a PEA and beyond. This outcome reflects a collaborative process with Colombian institutions and our confidence in the regulatory environment," stated Ian Harris, chief executive officer.

Title integration context

The integration of titles 131 and 141 is a key tenure milestone that reinforces a clear, long-term framework for advancing Mocoa. The company believes it is among the first in Colombia to achieve title integration with no overlap with forestry reserves or protected areas, following the boundary clarification announced in November, 2024 (refer to news release dated Nov. 12, 2024). This reserve boundary update, voluntary return of overlapping areas and now title integration, reflects a co-ordinated process with Colombian authorities and signals strong institutional alignment to advance the project. Importantly, the current mineral resource estimate remains unchanged and fully contained within the integrated title. Only minor portions of peripheral exploration targets were affected as part of the boundary rationalization.

In Colombia, adjacent concessions held by the same operator can be merged into a single title with approval from the ANM, consolidating legal, technical and environmental frameworks under one concession. The approval establishes a new concession term from the date of integration, resetting Mocoa to a new exploration stage while simplifying permitting, reducing administrative complexity and aligning the land package with the core resource and priority expansion areas.

Over all, this milestone represents a net result of collaborative efforts between the company and Colombian authorities, reinforcing both the company's environmental commitment and a stable, aligned pathway to advance Mocoa at scale.

Third drill rig mobilization

The company has successfully mobilized a third drill rig to the Mocoa project, increasing total active capacity to three rigs as part of the fully financed 2026 exploration program (refer to news release dated Feb. 17, 2026). This expanded capacity is expected to accelerate drilling rates and provide flexibility to advance resource conversion, expand the current MRE footprint, and test high-priority targets across the broader district, reflecting the company's continued confidence in the growth potential of this clustered porphyry system.

Qualified person and technical notes

Edwin Naranjo Sierra, vice-president of exploration for Copper Giant, is the designated qualified person within the meaning of National Instrument 43-101 -- Standards of Disclosure for Mineral Projects, and has reviewed and approved the technical information in this news release. Mr. Naranjo holds an MSc in earth sciences and is a fellow of the Australasian Institute of Mining and Metallurgy (FAusIMM). Mr. Naranjo is not independent of the company.

Mocoa's mineral resource estimate comprises inferred resources of 12.7 billion pounds (Blb) copper-equivalent (CuEq) at an average grade of 0.51 per cent CuEq, including 7.7 Blb of copper at 0.31 per cent Cu and 1.0 Blb of molybdenum at 0.039 per cent Mo (molybdenum), within 1,120 million tonnes (Mt). CuEq values are calculated using a Cu-to-Mo value ratio of 1:5.278, incorporating both metal prices and metallurgical recoveries.

Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that all or any part of the inferred mineral resources will be upgraded to an indicated or measured category.

About the Mocoa porphyry system

The Mocoa project is located in Colombia's Department of Putumayo, approximately 10 kilometres from the town of Mocoa in the country's south. Copper Giant controls more than 132,499 hectares of district-scale tenure through granted titles and applications, covering a significant portion of the Jurassic porphyry belt -- an underexplored and highly prospective metallogenic corridor within the northern Andes.

Mocoa was first identified in 1973 through a regional geochemical survey conducted by the United Nations and the Colombian government. Follow-up programs between 1978 and 1983 included geological mapping, IP and magnetic geophysics, surface sampling, drilling, and metallurgical testing. Subsequent drilling by B2Gold in 2008 and 2012 refined the geological interpretation and confirmed the large scale of the system.

The deposit is hosted in Middle Jurassic dacite and quartz-diorite porphyries intruding andesitic to dacitic volcanics of the Central Cordillera, a 30-kilometre-wide tectonic belt that extends into Ecuador and also contains major porphyry systems such as Mirador, Warintza, San Carlos and Panantza. Mocoa exhibits classic porphyry-style zonation with a potassic core surrounded by sericite and propylitic alteration. Mineralization consists principally of disseminated chalcopyrite and molybdenite, accompanied locally by bornite and chalcocite, and is associated with stockwork veining and hydrothermal breccias.

A distinguishing geological feature of Mocoa is the presence of a fertile magmatic window spanning roughly 10 million years, a prolonged and unusually productive interval of magma generation and evolution that is not commonly observed in other Jurassic porphyry systems within the same belt. This extended fertile period provides a compelling explanation for the system's large metal endowment, broad alteration footprint, and overlapping intrusive and hydrothermal events.

The deposit demonstrates more than 1,000 metres of vertical continuity, with multiple intrusive phases, brecciation episodes, and vein generations reflecting a dynamic and long-lived magmatic-hydrothermal evolution, likely influenced by more than one porphyry centre. Mocoa remains open in all directions, and several satellite targets across the broader land package support the interpretation of a district-scale mineralized system.

Mocoa's mineral resource estimate comprises inferred resources of 12.7 billion pounds (Blb) copper-equivalent (CuEq) at an average grade of 0.51 per cent CuEq, including 7.7 Blb of copper at 0.31 per cent Cu and 1.0 Blb of molybdenum at 0.039 per cent Mo, within 1,120 million tonnes (Mt).
