Copper Giant completes first drill hole at East Valley

Mr. Ian Harris reports COPPER GIANT COMPLETES FIRST DRILL HOLE AT EAST VALLEY TARGET, CONFIRMING PORPHYRY-STYLE MINERALIZATION BEYOND THE MOCOA RESOURCE FOOTPRINT The first drill hole at the East Valley target, MD-048, has intersected porphyry-style mineralization, including chalcopyrite, molybdenite, sphalerite and galena. This marks the first ever drill test in this highly prospective area, located well beyond the current resource footprint of Mocoa. Two rigs are currently active as part of Copper Giant's 14,000-metre resource expansion program at the company's flagship Mocoa copper-molybdenum project in Putumayo, Colombia. "This first hole at East Valley has given us a much clearer understanding of its geology and the direction mineralization may extend. The east-dipping orientation of molybdenite and polymetallic veinlets, together with surface anomalies, points to a potential feeder zone in untested ground. Gold and silver are almost negligible at the current deposit area, and the stronger polymetallic signature confirms that East Valley is geochemically distinct. With these results, we now have clear vectors for the next stage of exploration," said Edwin Naranjo Sierra, vice-president of exploration. Hole MD-048 Drill hole MD-048 is the first hole completed at the East Valley target, a previously untested area located well beyond the current resource footprint of the Mocoa porphyry copper-molybdenum project. The hole was designed to test a Cu-Mo soil and rock anomaly, and was completed to a depth of 785.3 metres, as part of Copper Giant's continuing 14,000-metre resource expansion program. Detailed logging confirms the presence of porphyry-style mineralization and hydrothermal alteration across several intrusive phases. The upper portion of the hole intercepted a strongly sericite-altered dacite porphyry (interpreted as part of a leach cap) characterized by disseminated pyrite, iron oxides and D-type veinlets, similar to those observed in the upper levels of the Mocoa deposit. At depth, alteration transitions to a chlorite-sericite alteration with the development of C- and D-type veinlets that locally reopened early dark micaceous veinlets. Several intrusive phases were recognized, including microdiorite (interpreted as E0-type) and microtonalite porphyries, all displaying overprinting alteration and sulphide mineralization dominated by pyrite and less content of chalcopyrite and galena. Additional intervals include brecciated tuff and chlorite-sericite-altered porphyry with sphalerite, galena, chalcopyrite and pyrite. The orientation of mineralized structures provides a key vector. Molybdenite veinlets trend west-northwest while polymetallic quartz-carbonate veinlets (sphalerite, pyrite and galena) trend north-northeast. Both sets dip eastward, away from Mocoa. In porphyry systems, zinc-lead veinlets are typically distal features, yet at East Valley, they dip directly into untested ground coincident with copper-molybdenum and zinc-lead soil anomalies. This strongly suggests a feeder zone east of MD-048. Systematic stepout drilling and expanded soil geochemistry are planned to test this hypothesis. The hole also intersected a low-grade, late-mineral porphyry phase with magnetite, pyrrhotite, hornblende, pyrite and chalcopyrite, interpreted as emplacement from a relatively oxidized, hydrous magma source. These north-northwest-trending late-stage intrusions are likely part of the causative system, contributing additional hydrothermal fluids that prolonged mineralization within the Mocoa district. They are comparable with late dikes observed in earlier holes, though less pervasively altered, and their presence reinforces the interpretation of a long-lived, multipulsed magmatic-hydrothermal system that remains open for further discovery. 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. Mineralized zones at Mocoa are bulk porphyry-style zones, and drilled widths are interpreted to be very close to true widths. Copper Giant operates according to a rigorous quality assurance and quality control protocol consistent with industry best practices. Core diameter is a mix of HQ and NQ depending on the depth of the drill hole. Diamond drill core boxes were photographed, sawed, sampled and tagged in maximum two-metre intervals, stopping in geological boundaries. Samples were bagged, tagged and packaged for shipment by truck from Copper Giant's core logging facilities in Mocoa, Colombia, to the ActLabs certified sample preparation facility in Medellin, Colombia. ActLabs is an accredited laboratory independent of the company. Samples are processed in the Medellin facilities where they are analyzed for copper, gold, silver, molybdenum, zinc and lead by four-acid digest atomic absorption analysis. The sample pulps are airfreighted from Medellin to the ActLabs certified laboratory in Guadalajara, Mexico, where they are analyzed for a suite of 57 elements using four-acid digest and ICP-MS. To monitor the continuing quality of assay data and the database, Copper Giant has implemented quality assurance/quality control protocols, which include standard sampling methodologies and the insertion of certified copper and molybdenum standard materials, blanks and duplicates (field, preparation and analysis) randomly inserted into the sampling sequence. The QA/QC program also includes continuing monitoring of data entry, QA/QC reporting and data validation. No material QA/QC issues have been identified with respect to sample collection, security and assaying. 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 Colombia. Copper Giant holds a district-scale land package of over 790 square kilometres through granted titles and applications, covering a substantial portion of the Jurassic porphyry belt -- an underexplored and highly prospective metallogenic zone in the northern Andes. Discovered in 1973 through a regional geochemical survey by the United Nations and the Colombian government, Mocoa has been the subject of multiple exploration campaigns. Between 1978 and 1983, follow-up work included geological mapping, induced polarization and magnetic geophysics, surface sampling, drilling, and metallurgical testing. Additional drilling by B2Gold in 2008 and 2012 helped shape the current geological understanding. The deposit is hosted in Middle Jurassic dacite and quartz-diorite porphyries intruding andesitic to dacitic volcanics within Colombia's central cordillera. This 30-kilometre-wide tectonic belt extends into Ecuador and hosts other major porphyry systems like Mirador, Warintza, San Carlos and Panantza. Mocoa displays a classical porphyry-style alteration zonation: potassic core, sericite halo and outer propylitic zone, with mineralization consisting of disseminated chalcopyrite and molybdenite, and local bornite and chalcocite, associated with stockworks and hydrothermal breccias. 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 was likely driven by more than one porphyry centre. 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. About Copper Giant Resources Corp.

Copper Giant was formed with a singular focus: to advance high-quality copper projects beyond resource definition responsibly, efficiently and with long-term positive impact. The company is led by a team with uncommon experience, having taken some of the few major copper mines developed in the past two decades from discovery through to construction. Copper Giant's current focus is the Mocoa copper-molybdenum deposit in southern Colombia, one of the largest undeveloped resources of its kind in the Americas. Recent exploration success has revealed potential well beyond its original footprint, highlighting Mocoa as a broader district-scale opportunity and the catalyst for the company's name and evolution.
