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.

Technical Overview

The Titac property forms a key part of the Company's South Contact Zone Project in the Duluth Complex of northeastern Minnesota. The project hosts an inferred mineral resource estimate at Titac South of 46.6 million tonnes grading 15% TiO2 (see the NI 43-101 technical report entitled "Technical Report and Mineral Resource Estimate for the South Contact Zone Project, St. Louis County, Minnesota, USA" with an effective date of September 18, 2024, filed on SEDAR+). Inferred mineral resources have a high degree of uncertainty as to their existence and as to whether they can be mined economically. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The 2026 drilling program was designed to test the distribution of copper mineralization within the known titanium resource at Titac South and to evaluate the effectiveness of 3D VTEM inversion as a targeting tool. The completed 3D inversion modelling refines the preliminary VTEM results released in May 2025 and identifies a number of previously unrecognized anomalies. Several of these targets exhibit coincident magnetic highs and conductive responses consistent with the geophysical signature of the known mineralized OUIs. Management considers these features prospective for additional titanium-vanadium-copper mineralization.

Drilling Program Design

The Phase 1 program consisted of a systematic six-hole fence across the Titac South intrusion, designed to verify and evaluate the presence, distribution and continuity of copper mineralization within and outside the OUI.

Initial Assay Results - Titac South

Assay results from the first three holes (TS26-002a, TS26-003 and TS26-005) confirm copper mineralization over broad intervals, as summarized in Table 1. All reported intervals are downhole lengths. True widths cannot currently be determined with confidence because of the irregular geometry of the mineralized zones.

3D VTEM Inversion and Targeting

The Company recently completed a full 3D inversion of VTEM airborne geophysical data, enhancing the resolution of both conductive and magnetic responses across the Titac property. The inversion modelling has identified four or five additional untested anomalies exhibiting coincident conductive and magnetic signatures consistent with known mineralized Oxide Ultramafic Intrusions at Titac South and Titac North (Figure 3). Drilling to date demonstrates alignment between these geophysical targets and observed sulphide mineralization, which supports the Company's exploration model.

Titac South is the location of the known inferred mineral resource estimate and where the most recent drilling was carried out. Inferred mineral resources have a high degree of uncertainty as to their existence and as to whether they can be mined economically. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Quality Assurance and Quality Control

Green Bridge Metals exploration samples were collected in accordance with industry standards and best practices. All new samples were submitted to Activation Laboratories Ltd. in Thunder Bay, Ontario, for geochemical analysis. Analytical methods included fire assay with ICP-OES analysis for gold and platinum group elements, sodium peroxide fusion with ICP-OES analysis for trace elements, and lithium metaborate fused-disc XRF analysis for major element composition. Activation Laboratories Ltd. is independent of the Company.
