Green Bridge Metals Completes Re-Sampling of Historical Core Assay and Geophysics Data for Skibo Prospect

Executive Summary

• Green Bridge Metals completed a historic core re‑sampling program at the Skibo Prospect, confirming extensive Cu‑Ni‑PGM mineralization over 200–400 m intervals in multiple holes.
• High‑grade massive and semi‑massive sulfide intercepts are spatially associated with mapped electromagnetic conductors, supporting a repeatable geophysical targeting framework for future drilling.
• The low‑cost program (< US$180k) enhances the geological model and provides a clear path for further exploration in the South Contact District of the Duluth Complex.

Key Details

• Program Scope: Re‑sampling of historic drill core to target unsampled intervals above/below previously assayed high‑grade zones; total cost < US$180,000.
• Mineralization Extent: Disseminated Cu‑Ni‑PGM mineralization identified over 200–400 m intervals in several historic holes.
• High‑Grade Intercepts: Massive and semi‑massive sulfide veins intersected within broader disseminated halos; highest grades coincide with electromagnetic conductors (e.g., holes with ≥1% Cu).
• Geophysical Correlation: Strong correlation between mineralized zones and mapped EM conductors; non‑mineralized historic holes lack such conductors, establishing a repeatable targeting methodology.
• Future Work: Planned drilling will focus on testing EM conductor trends and step‑out targets beyond historic core locations to evaluate system continuity.
• Technical Validation: Independent QA/QC performed by ALS Minerals (historic data) and Activation Labs (new assays); Qualified Persons Michael B. Dufresne, Andrew J. Turner, Fallon T. Clarke, Christian Bohm, and Ajeet Milliard reviewed and approved the technical information.
• Cost Efficiency: The re‑sampling effort provided a comprehensive mineralization picture at a fraction of typical drilling costs.
