Green Bridge Metals Reports Visible Copper Sulfide Mineralization in Initial 2026 Titac Drilling, Duluth Complex Minnesota

Rhea-AI Summary

Green Bridge Metals (OTCQB:GBMCF) reported visible chalcopyrite-bearing sulfide mineralization in the first three holes of its 2026 Titac Phase 1 drill program, completing 1,196 metres across TS26-002a, TS26-003 and TS26-005.

Ilmenite was observed throughout the Oxide Ultramafic Intrusion, which corresponds to the Titac South inferred resource of ~46.6 million tonnes at 15% TiO2. Samples are en route to an independent lab; assays are pending and will be released after validation.

Positive

• Completed 1,196 metres in three initial drill holes (TS26-002a, TS26-003, TS26-005)
• Visible chalcopyrite-bearing sulfide mineralization across ~100–450 metre intervals
• Pervasive ilmenite observed consistent with existing Titac South TiO2 resource
• Titac South inferred resource ~46.6 million tonnes at 15% TiO2

Negative

• Assay results are still pending, so copper grades and economic significance are unconfirmed
• Reported mineralization remains within an inferred category and lacks demonstrated economic viability
• Board-approved grant of 11,900,000 RSUs and 2,150,000 options may dilute shareholders

VANCOUVER, BC / ACCESS Newswire / March 26, 2026 / Green Bridge Metals Corporation (CSE:GRBM)(OTCQB:GBMCF)(FWB:J48, WKN: A3EW4S) ("GreenBridge" or the "Company") is pleased to provide an update on its ongoing Phase 1 diamond core drilling program at the Titac Project, located within the Company's South Contact District in northeastern Minnesota, U.S.A.

The Titac Project hosts a large titanium-bearing intrusion within the Duluth Complex and is currently being evaluated for its potential to host copper mineralization associated with the Oxide Ultramafic Intrusion that contains the existing titanium dioxide resource. Please see the Company's technical report dated September 18, 2024, a copy of which may be obtained under the Company's profile at www.sedarplus.ca for more information.

Inferred mineral resources have a great amount 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 the inferred mineral resources will ever be upgraded to a higher category. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Since commencing drilling in late January 2026, as announced on January 22, 2026, the Company has completed three diamond drill holes across the Titac South deposit. Drill holes TS26-002a (309 m), TS26-003 (410 m), and TS26-005 (477 m) have been completed for a total of 1,196 metres drilled to date as part of a planned six-hole fence designed to systematically evaluate copper mineralization across the intrusion.

During geological logging, all three holes intersected visually identifiable sulfide mineralization across broad intervals. Observed sulfide minerals include chalcopyrite with associated sulfides occurring as disseminations and veinlets over intervals of approximately 100-450 metres downhole. Ilmenite, the principal titanium-bearing mineral within the Titac South resource, is observed throughout the intrusion in each hole.

Mineral identifications are based on visual logging and remain subject to laboratory assay confirmation.

Highlights

• Three drill holes completed totalling 1,196 metres during the first phase of the 2026 Titac drill program.

• Visible chalcopyrite-bearing sulfide mineralization observed across intervals of approximately 100-450 metres during geological logging.

• Ilmenite observed throughout the Oxide Ultramafic Intrusion consistent with the Titac South titanium dioxide resource.

• Samples prepared for shipment to an independent laboratory; assays pending.

Ajeet Millard, Chief Geologist of Green Bridge Metals, commented:

"The visual observations from the first three holes at Titac South are consistent with the geological and geophysical model that guided our targeting. Chalcopyrite-bearing sulfide mineralization has been observed across intervals within the Oxide Ultramafic Intrusion, while pervasive ilmenite remains evident throughout the core. These preliminary observations provide support to the interpretation that copper mineralization may be spatially associated with the titanium-bearing host intrusion. Assay results will be necessary to confirm these observations and refine our understanding of potential mineralization within the system."

Key observations to date include:

• Chalcopyrite visually identified as the dominant copper-bearing sulfide mineral.

• Sulfide mineralization occurring as disseminations and veinlets within the Oxide Ultramafic Intrusion.

• Pervasive ilmenite present throughout the drill core.

Core logging, sampling, and QA/QC procedures are ongoing. Samples from completed holes are being prepared for shipment to an independent laboratory for assay analysis. Results will be released once received and validated.

Program Progress

The Phase 1 drill program is designed to evaluate copper mineralization within and adjacent to the existing Titac South Inferred Mineral Resource Estimate of approximately 46.6 million tonnes at 15% TiO2, as reported in the NI 43-101 Technical Report dated September 18, 2024.

Inferred mineral resources have a great amount 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 the inferred mineral resources will ever be upgraded to a higher category. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Fence-style drill sections are being used to systematically transect the deposit and better understand the geological and structural controls on copper mineralization within the intrusion.

The Company also announces that its board of directors has approved the grant of an aggregate of 2,150,000 incentive stock options (the "Options") and 11,900,000 restricted share units ("RSUs") to directors, officers and certain consultants of the Company, pursuant to the Company's equity incentive plan.
