Copper Giant drills 208 m of 0.68% CuEq at Mocoa

Executive Summary

• Copper Giant Resources Corp. released assay results from drill hole MD-052 at its Mocoa copper-molybdenum project in Colombia, extending a recently discovered high-grade porphyry-related zone by 250 metres along strike.
• The intercept confirms the zone remains open laterally and at depth, with mineralization projecting southward toward the La Estrella target, suggesting a potential second porphyry centre and significant exploration upside.
• Drilling continues with two rigs as part of a 14,000-metre resource expansion program aimed at defining the geometry of the emerging porphyry system and expanding the existing inferred mineral resource estimate.

Key Details

• Drill Hole MD-052 Intercept: 208 metres grading 0.68% CuEq (0.47% Cu and 0.04% Mo), starting at 768 metres downhole.
• Geological Context: The intercept is located in the East Valley zone, extending the high-grade zone southward and downward. It connects East Valley geology with the Mocoa porphyry system and links previous high-grade mineralization (MD-046, MD-047, MD-050) to the East zone.
• Mineralization Characteristics: The hole intersected strongly potassic-altered (secondary biotite) early microdiorite porphyry with dense stockwork-style A- and B-type veinlets at 859 metres. The hole terminated in a brecciated porphyry with intense chlorite-sericite alteration, containing molybdenite and minor chalcopyrite.
• Resource Estimate Context: Results build on the 2025 Mocoa mineral resource estimation update, which reported inferred mineral resources of 12.7 billion pounds copper equivalent at an average grade of 0.51% CuEq, including 7.6 billion pounds of copper at 0.31% Cu and 1.0 billion pounds of molybdenum at 0.039% Mo, within 1.12 million tonnes.
• Exploration Strategy: Two drill rigs are currently operating. The 2025/2026 drilling plan focuses on expanding the high-grade zone through targeted stepouts and directional drilling to test prospective areas outside the current MRE footprint.
• Future Potential: The high-grade trend projects toward the La Estrella area, indicating potential extension into shallower depths and reinforcing the interpretation of a multicentred porphyry system.

Notable Quotes

• "MD-052 builds directly on the success of MD-047 and MD-050, extending the recently discovered third high-grade zone and reinforcing the geometry of this emerging porphyry centre. The zone remains open laterally and at depth, supporting continued improvements to the copper and molybdenum grade profile." — Edwin Naranjo Sierra, Vice-President of Exploration.
• "Notably, the high-grade trend also projects southward toward the La Estrella target, indicating potential extension of this zone into a shallower area and opening an important new front for expansion." — Edwin Naranjo Sierra, Vice-President of Exploration.
