Copper Giant Resources Corp. Reports Assay Results for Infill Hole MD-066 and Corridor Hole MD-065 at Mocoa Copper-Molybdenum Porphyry Project in Putumayo, Colombia
Copper Giant Resources Corp. reported assay results from infill hole MD-066 and corridor hole MD-065 at its flagship Mocoa copper-molybdenum porphyry project in Putumayo, Colombia. MD-066 intersected 584 metres of continuous mineralization grading 0.73% CuEq (0.40% Cu and 0.062% Mo), including a higher-grade core of 183 metres of 0.94% CuEq (0.54% Cu and 0.076% Mo), well above the current MRE average of 0.51% CuEq (0.31% Cu and 0.039% Mo), confirming and locally exceeding the resource model that is used for the anticipated upcoming Preliminary Economic Assessment (PEA). MD-065, the first hole collared at the La Estrella target and the first assay result from the Company's third drill rig, reached the southeastern margin of the Mocoa system, returning 176 metres of 0.30% CuEq (0.15% Cu and 0.027% Mo) from 610 metres, outside the current resource footprint. Grade increased continuously with depth and the hole ended in mineralization with the final 49 metres averaging 0.34% CuEq (0.10% Cu and 0.046% Mo), open toward the higher-grade core to the northwest. Together these holes document a model reproducing grade and continuity at infill spacing, and mineralization beyond the MRE footprint. Drilling continues at La Estrella, with assays pending. MD-066 validates and locally exceeds the resource model: 584 metres of continuous mineralization grading 0.73% CuEq (0.40% Cu and 0.062% Mo) from its kick-off point, including a higher-grade core of 183 metres of 0.94% CuEq (0.54% Cu and 0.076% Mo), which is well above the current MRE average of 0.51% CuEq (0.31% Cu and 0.039% Mo), confirming the continuity and predictability of Cu-Mo grade domains within the resource model. MD-065 extends the Mocoa system beyond the resource footprint: the first hole collared at the La Estrella target, and the first completed by the Company's third drill rig, reached the southeastern margin of the Mocoa system, returning a broad 176-metre intercept of 0.30% CuEq (0.15% Cu and 0.027% Mo) above the 0.25% CuEq resource cutoff and outside the current resource footprint. MD-065 ended in the strongest mineralization it intersected: grade increases continuously with depth, with the final 49 metres averaging 0.34% CuEq (0.10% Cu and 0.046% Mo), including 12 metres of 0.46% CuEq (0.08% Cu and 0.071% Mo) from 757 metres, above the current MRE average molybdenum grade of 0.039% Mo. The hole ended in mineralization and remains open toward the higher-grade core to the northwest. Drilling continues at La Estrella: 1,500 metres completed to date; assays pending. Hole MD-066 was completed as a directional daughter hole from mother hole MD-064, part of the Company's infill drilling and resource-conversion strategy within the current MRE footprint. The hole was designed to test the grade and continuity of the resource model at tighter drill spacing, the same model that will underpin the upcoming PEA. MD-066 targeted an area of wider historical drill spacing with the objective of increasing geological confidence in the higher-grade domains of the deposit. Hole MD-066 returned broad, continuous and high-grade copper-molybdenum mineralization over essentially its entire length. The hole intersected 584 metres of 0.73% CuEq (0.40% Cu and 0.062% Mo) from its kick-off at 169 metres, including 230 metres of 0.89% CuEq (0.54% Cu and 0.065% Mo) from 312 metres and a higher-grade core of 183 metres of 0.94% CuEq (0.54% Cu and 0.076% Mo) from 362 metres. These grades are consistent with, and locally exceed, the values modelled by the current MRE block model, indicating that the resource model is effectively predicting both grade distribution and mineralized continuity in Mocoa. MD-065 is the first hole completed by the Company's third drill rig, was collared at the La Estrella target, outside the MRE footprint and drilled northwest toward the Mocoa deposit. The hole intercepted a thick sequence of weakly mineralized volcanic rocks, with copper values locally exceeding 0.1%, before entering the Mocoa porphyry system at depth. Copper grades increase downhole to a maximum of 0.19% Cu between 650 and 700 metres downhole and then decline, while molybdenum grades increase continuously to the end of the hole, validating the geological, geochemical and geophysical targeting that guided the third rig to this area. The hole returned 176 metres of 0.30% CuEq (0.15% Cu and 0.027% Mo) from 610 metres, above the 0.25% CuEq pit-constrained cutoff used in the current MRE and outside the existing resource footprint. The final 49 metres of the hole average 0.34% CuEq (0.10% Cu and 0.046% Mo) and include 12 metres of 0.46% CuEq (0.08% Cu and 0.071% Mo) from 757 metres, the highest-grade interval of comparable length in the hole. The intercept lies approximately 150 metres outside the nearest pit-constrained resource, leaving that untested ground between MD-065 and the resource edge in the Mocoa–La Estrella corridor. Along the hole, measured copper-to-molybdenum ratio decreases from approximately 22:1 across the first 610 metres to approximately 11:1 between 600 and 700 metres and approximately 2:1 over the final 50 metres, against approximately 8:1 for the current MRE as a whole. The lowermost 35 metres of the hole, from 751 metres downhole, is logged as quartz-diorite porphyry and averages 0.077% Cu and 0.046% Mo; the same lithology logged in MD-066, over 11 metres from 362 metres downhole, averages 0.560% Cu and 0.030% Mo, a ratio of approximately 19:1. Quartz-molybdenite veins are first logged at 612 metres and increase in density to the end of the hole. As expected for a hole drilled from outside the deposit inward, MD-065 encountered the mineralized margin first, with grade increasing as it approached the porphyry core. MD-065 was completed to its planned depth of 786 metres, ended in mineralization, and remains open toward the higher-grade core to the northwest. Together with MD-061 and MD-063, MD-065 delivers the maiden drilling at La Estrella as announced in June 22, 2026, and completes the first drill test of the Mocoa–La Estrella corridor from the La Estrella end. Copper Giant operates according to a rigorous Quality Assurance and Quality Control (QA/QC) 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 2-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 4-Acid digest Atomic Absorption (AA) analysis.
