Copper Giant’s Mocoa Drilling Extends Porphyry Footprint; MD-054 Reveals Stronger Southern Mineralization

Copper Giant wrapped its 2025 exploration program at the Mocoa porphyry with assays from two targeted holes that shift the geological and resource story southward. MD-053 tested continuity toward La Estrella and confirmed the porphyry architecture persists beyond the current footprint, albeit at modest concentrations; its value is in extending the structural model rather than immediate economic uplift. MD-054 penetrated the southern margin and returned a broad 253-metre zone averaging about 0.40% copper-equivalent, including a higher-grade 61-metre core near 0.61% CuEq, results that exceed the corresponding blocks in the latest resource model. Over the year the company drilled roughly 11,400 metres and continues to operate two rigs on site to support technical follow-up and targeted infill. The recently filed resource update increases inferred tonnes substantially to roughly 1.12 billion tonnes at an average mid‑half‑percent CuEq, representing a material rise in contained metal versus the prior estimate. Geologically, Mocoa presents a vertically persistent system with multiple higher-grade cores and open strike and depth potential, offering clear vectors for step-out and conversion drilling. The MD-054 intercepts specifically indicate that areas previously flagged as low priority due to sparse shallow drilling can host meaningful mineralization when tested on section. Despite the scale and encouraging continuity, the bulk of the inventory remains classified as inferred, so converting tonnage to higher confidence categories will require systematic infill, hydrological and geotechnical work. Assay and QA/QC workflows were reported to follow accredited laboratory procedures and industry protocols, supporting data reliability for modelling and planning. Economically meaningful outcomes will depend on the pace and success of the 2026 program, permitting progress, and subsequent resource conversion. For stakeholders, the combination of expanded tonnage, persistent vertical continuity, and targeted higher-grade cores creates a stronger development narrative, but it coexists with customary exploration and country‑level risks. The near-term technical agenda—focused infill along southern and other growth vectors, environmental baseline studies, and early de‑risking—will shape whether the geological potential translates into a mineable project. In sum, the 2025 results materially sharpen the prospect inventory at Mocoa while leaving the decisive work of conversion and permitting ahead.
