Green Bridge Metals Commences Diamond Drilling Program at the Titac Project, Minnesota, USA

Executive Summary

• Green Bridge Metals announces the start of a Phase 1 diamond‑core drilling program at its Titac Project (South Contact District, Minnesota) to evaluate copper mineralization associated with the existing TiO₂ resource.
• The initial drill fence will consist of six holes, targeting ~300 m depth and ~1,800 m total length, spaced ~50 m apart across the Titac South deposit.
• Results are intended to define geological controls on disseminated copper, validate historic copper assays, and guide subsequent drilling phases for both copper expansion and potential new targets.

Key Details

• Program Scope: 6 diamond‑core holes; target depth ≈300 m per hole; total planned drill length ≈1,800 m; average spacing ~50 m; fence‑style layout transecting the known TiO₂ resource.
• Objectives:
• Define structural and geological controls on copper mineralization.
• Validate historic copper assay results not previously incorporated into the titanium‑focused model.
• Test spatial relationship between copper zones and overlapping magnetic/conductive geophysical anomalies identified from recent VTEM, 3D magnetic and conductivity inversions (2025).
• Historical Context: 32 historic diamond holes contributed to the NI 43‑101 resource estimate; 26 of those intersected copper mineralization that was not modeled. Copper is consistently associated with the Oxide Ultramafic Intrusion (OUI) hosting the TiO₂ resource.
• Exploration Rationale: Modern geophysical data (VTEM EM, magnetic & conductivity inversions) highlight overlapping conductive and magnetic anomalies correlating with known copper zones; these guide target selection for Phase 1.
• Future Drilling Outlook (contingent on results):
• Follow‑up drilling at Titac South to test continuity/extent of copper mineralization.
• Initial testing of similar anomalies at Titac North.
• Drill testing of a newly identified deep conductive/magnetic anomaly south of Titac South.
• Qualified Person: Ajeet Milliard, Chief Geologist, has reviewed and approved the technical information per NI 43‑101 standards.

Notable Quotes

“The commencement of drilling at Titac is an important milestone for Green Bridge as we begin systematically testing the copper potential of a project that already hosts a titanium resource.” – David Suda, President & CEO

“The results of our 3D geophysical inversions are highly encouraging…provides the confidence and technical foundation to initiate drilling, with a clear focus on expanding known copper mineralization where these anomalies occur.” – David Suda, President & CEO (Technical)
