Copper Giant Initiates Next Phase Metallurgical Testing At Mocoa As Part Of Integrated Strategy for the 2026 PEA Advancement

VANCOUVER, BC, March 2, 2026 /CNW/ - Copper Giant Resources Corp. ("Copper Giant" or the "Company") (TSXV: CGNT) (OTCQB: LBCMF) (FRA: 29H0) is pleased to announce the engagement of Frank Wright as independent metallurgical consultant and the selection of SGS Canada ("SGS") as the certified and independent company to execute the next phase of metallurgical testing at its flagship Mocoa copper–molybdenum porphyry project in Putumayo, Colombia. Mocoa is a Jurassic age porphyry Cu-Mo deposit where drilling to date has delineated continuous copper and molybdenum mineralization from surface to depth exceeding 1,000 vertical metres. This program represents the continuation and expansion of the metallurgical work first reported in October 2025, where initial bench-scale flotation testing demonstrated rougher copper recoveries of up to 92% and rougher molybdenum recoveries of up to 97% from a representative composite sample. As previously stated, additional variability testing and more advanced circuit evaluation were identified as the logical next steps toward supporting a future Preliminary Economic Assessment ("PEA"). The Company is now executing that next phase.

"Our initial metallurgical results confirmed that Mocoa responds well to conventional processing and exceeded recovery assumptions used in the resource model. As we stated at the time, variability and more advanced circuit testing were the next logical steps. This program is the continuation of that strategy. By strengthening metallurgical oversight and working with Frank and SGS, we are advancing toward PEA-level technical confidence in a disciplined and methodical way." – Edwin Naranjo Sierra, Vice-President of Exploration.

From Baseline Recoveries to Integrated Metallurgical Definition

Historical open-cycle metallurgical¹ testing completed at Dawson Metallurgical Laboratories, produced a copper concentrate grading 24.2% Cu with a recovery of 85.9%, and a molybdenum concentrate grading 55.14% Mo with a recovery of 82.7%. Both concentrates were reported as clean and free of deleterious elements. These recoveries are considered more representative of the range that may be expected for marketable concentrate production and provide an appropriate benchmark for future economic evaluation scenarios.
More recent metallurgical testing established that Mocoa mineralization responds well to conventional flotation processing and confirmed chalcopyrite and molybdenite as the dominant recoverable minerals (refer to news release dated October 2, 2025). That initial campaign was based on a single ~130 kg composite and was designed to establish baseline rougher flotation performance and metallurgical response. While rougher recoveries demonstrated strong flotation kinetics, further cleaning-stage testing and circuit refinement are required to define recoveries associated with final, saleable concentrate grades. This is a critical parameter for economic evaluation. The newly initiated program builds directly on that foundation and expands the scope toward integrated, PEA-level metallurgical definition. Selection of ~675-kilograms has been prepared from representative crushed assay rejects distributed across the current Mineral Resource Estimate¹ ("MRE") footprint. The selection is based on individual assay intervals (primarily 2-metres in length), combined to form composites of at least 10 m, and was designed to capture variability in lithology, alteration, and grade domains relevant to potential PEA development scenarios.

The current phase of testing includes mineralogical characterization, grindability assessment, flotation circuit refinement, and supporting studies designed to strengthen process assumptions appropriate for PEA-level evaluation. The objective is to systematically evaluate metallurgical variability, integrate geological domains with process response and to better define the relationship between concentrate grade and recovery, recognizing that recovery assumptions must be evaluated in conjunction with the production of marketable copper and molybdenum concentrates. This staged and disciplined approach is consistent with industry's best practices for large-scale porphyry systems.

Strengthening Technical Oversight

Frank Wright has been engaged to oversee the design, supervision, and interpretation of this next-stage metallurgical program. His experience in copper porphyry systems and mineral processing evaluation enhances the integration between geology, metallurgy, and engineering assumptions. Following review of multiple proposals, SGS was selected as the certified and independent metallurgical laboratory based on technical capability, international experience in copper–molybdenum systems, and laboratory capacity. The program will be conducted at SGS's Canadian metallurgical facilities at Burnaby, BC and will be managed by PhD Jesse Ding (Senior Metallurgist).

Advancing Toward PEA-Level Technical Confidence

As outlined in the Company's 2026 Exploration Plan, Copper Giant is advancing drilling, geotechnical, hydrogeological, and metallurgical programs in parallel to systematically de-risk the Mocoa Project. While drilling expands and upgrades the resource base, this metallurgical phase ensures that processing assumptions evolve alongside geological confidence. The integration of these workstreams is intended to position Mocoa for a disciplined transition into PEA-level project evaluation.

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 Ha 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 ten 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 center. 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 Estimate¹ comprises Inferred resources of 12.7 billion pounds (Blbs) copper-equivalent (CuEq*) at an average grade of 0.51% CuEq*, including 7.7 Blbs of copper at 0.31% Cu and 1.0 Blbs of molybdenum at 0.039% Mo, within 1,120 million tonnes (Mt).
