COPPER GIANT DEFINES THIRD HIGH-GRADE PORPHYRY CORE AT MOCOA AND CONFIRMS NORTHERN EXTENSION OF BRECCIA CORRIDOR

Executive Summary

• Copper Giant reported assay results from drill holes MD‑049 and MD‑050 at the Mocoa copper‑molybdenum project, confirming a northern extension of the breccia corridor and defining a third high‑grade porphyry core.
• Hole MD‑049 intersected 477 m averaging 0.37 % CuEq (including two sub‑zones of 0.49 % and 0.43 % CuEq) and a final 76 m at 0.39 % CuEq*, demonstrating that higher‑grade mineralization extends northward beyond previously drilled ground.
• Hole MD‑050 intersected 316 m averaging 0.35 % CuEq (including a 145 m zone of 0.60 % CuEq), establishing a new high‑grade core open laterally and at depth.

Key Details

• Hole MD‑049 – Total depth 1,085 m
• Overall interval: 1,085 m @ 0.21 % CuEq* (0.17 % Cu, 0.01 % Mo)
• Core high‑grade interval: 477 m @ 0.37 % CuEq* (0.30 % Cu, 0.02 % Mo)
  • Sub‑zone 1: 200 m @ 0.49 % CuEq* (0.37 % Cu, 0.03 % Mo)
  • Sub‑zone 2: 71 m @ 0.43 % CuEq* (0.39 % Cu, 0.01 % Mo)

• Final 76 m @ 0.39 % CuEq* (0.37 % Cu, 0.005 % Mo)

• Hole MD‑050 – Total depth 952 m

• Overall interval: 952 m @ 0.16 % CuEq* (0.12 % Cu, 0.01 % Mo)

• High‑grade core: 316 m @ 0.35 % CuEq* (0.25 % Cu, 0.02 % Mo)

  • Highest zone: 145 m @ 0.60 % CuEq* (0.39 % Cu, 0.05 % Mo)

• Assay methodology – CuEq* calculated as Cu % + 4.2 × Mo % using metal prices of US$4.00/lb Cu and US$20.00/lb Mo with recoveries of 90 % Cu and 75 % Mo; grades are uncut.

• Operational context – Two drill rigs continue a 14,000‑m resource expansion program; new lower‑elevation pads are being advanced to increase drilling efficiency and accelerate step‑out work on the newly identified high‑grade zone.

• Geological significance

• Confirms that the breccia corridor extends further north than previously modeled, opening additional exploration targets.

• Establishes a third high‑grade porphyry core, adding to two existing cores and indicating multi‑centered mineralization at Mocoa.

• Qualified Person – Edwin Naranjo Sierra, Vice‑President of Exploration, NI 43‑101 Qualified Person, reviewed and approved the technical information.

Notable Quotes

• Edwin Naranjo Sierra (VP Exploration): “MD‑049 confirmed our hypothesis that the breccia corridor extends further north… MD‑050 established a new third high‑grade porphyry core… all three high‑grade centers remain open at depth and laterally.”
• Ian Harris (President & CEO): “Metallurgy has exceeded assumptions, and now drilling has confirmed a third high‑grade core… Mocoa keeps delivering across geology, recoveries, and infrastructure advantages…”
