Green Bridge Metals Reports Initial Assays from Drill Program

About this update from Green Bridge Metals Corporation

VANCOUVER, BC / ACCESS Newswire / May 27, 2026 / Green Bridge Metals Corporation (CSE:GRBM) (OTCQB:GBMCF) (FWB:J48, WKN:A3EW4S) ("Green Bridge" or the "Company") is pleased to report initial assay results from its Phase 1 diamond drill program at the Titac Project, located within the Company's South Contact District in northeastern Minnesota, U.S.A. (Figure 1). The Company has completed six diamond core drill holes in the Phase 1 program at Titac South. Assay results from the first three holes confirm the presence of broad intervals of copper mineralization associated with the Oxide Ultramafic Intrusions ("OUI"), while assays from the remaining three holes, including a step-out hole targeting a previously untested geophysical anomaly, remain pending. Initial results from the first three holes indicate potential polymetallic mineralization within the OUI, including copper (Cu), titanium dioxide (TiO2), vanadium pentoxide (V2O5), and platinum group elements (PGE) (Figure 2; Table 1). David Suda, President and Chief Executive Officer, commented: "We have completed the full six-hole program at Titac and sulphide mineralization has been observed in core from every drill hole to date. The broad intervals of copper mineralization within the Oxide Ultramafic Intrusion support our geological model and suggest that mineralization may potentially extend beyond the currently tested area. With assays pending from the final three holes, including a step-out test of a new geophysical anomaly, we are entering an important phase in evaluating the potential scale of the system." Highlights Six of six holes completed in the Phase 1 Titac South program intersected observable sulphide mineralization. Initial assays from the first three holes confirm broad copper mineralization within the OUI. TS26-005 returned 152 m @ 0.31% Cu, 13.7% TiO2 and 0.15% V2O5. TS26-003 returned 190 m @ 0.30% Cu, 11.4% TiO2 and 0.13% V2O5, including 14.0 m @ 0.48% Cu, 13.8% TiO2 and 0.13% V2O5. TS26-002a returned 54.0 m @ 0.20% Cu, 9.3% TiO2 and 0.10% V2O5. Copper mineralization was observed over broad downhole intervals within the OUI. Drilling results are consistent with targets generated from 3D VTEM inversion modelling. Multiple untested geophysical anomalies have been identified across the property. Figure 1. Map of the South Contact Zone Project showing the Titac property at the southern end. ...
