GREEN BRIDGE METALS CORPORATION ANNOUNCES PHASE 2 DIAMOND DRILL PROGRAM AT THE TITAC TITANIUM-COPPER-VANADIUM PROJECT, MINNESOTA, USA

Green Bridge Metals Corp. has outlined a phase 2 diamond core drill program at the company's Titac titanium-copper-vanadium project, located in St. Louis county, Minnesota, U.S., within the Duluth complex, following the successful outcomes from the phase 1 drilling at the Titac South prospect earlier in 2026 (please see the news release dated Sept. 10, 2026), with the phase 2 program expected to commence in October, 2026.

Highlights:

• Planned phase 2 drilling program accelerated: six holes totalling 2,500 to 3,000 metres planned at Titac North, commencing in October, 2026;
• Goal to expand the inferred mineral resource: test the potential to expand the existing Titac South titanium inferred mineral resource into Titac North:
  • Please see the company's technical report dated Sept. 18, 2024, a copy of which may be obtained under the company's profile on SEDAR+ 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;
• Building a multimetal resource: phase 1 and phase 2 data to evaluate inclusion of copper and vanadium toward an updated Titac MRE (mineral resource estimate);
• Advancing toward a PEA (preliminary economic assessment): generate key technical data for future resource and economic studies;
• Planning for growth: 14 drill sites fully permitted by St. Louis County, providing flexibility for follow-up drilling and additional exploration work through April, 2028.

David Suda, president and chief executive officer, commented: "The results from our phase 1 drilling at Titac South gave us the confidence to accelerate the next stage of work at Titac. With phase 2, our drilling focus shifts to Titac North, where six planned holes will test the potential to expand the known mineralized system beyond the existing Titac South titanium inferred resource. We will integrate these new results with our phase 1 work to evaluate the potential incorporation of copper and vanadium into a future updated Titac resource. Our objective is to build on an established titanium inferred resource while developing a much clearer understanding of the broader potential multimetal opportunity at Titac. At the same time, our evolving 3-D geological and geophysical interpretation continues to identify opportunities for future growth beyond the areas being tested in the current program."

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.

Program objectives

The phase 2 program is designed to achieve the following objectives:

1. Drilling at Titac North (six drill holes) aims to expand the existing titanium MRE at Titac South, with a goal to augment the resource to cover both Titac North and South prospects;
2. Generate a copper resource for Titac South with existing data, which could expand with the planned phase 2 drilling at Titac North;
3. Evaluate systematic multielement assaying for other metals (V (vanadium), Ni (nickel), Co (cobalt), PGMs (platinum group metals)), which are not currently included in the MRE;
4. Generate technical data to support the company's longer-term objective of advancing Titac toward a PEA, subject to results and further studies.

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.

Program overview

The phase 2 drill program will consist of optimized drilling designed to systematically test for titanium-copper-vanadium mineralization delineated by historic drilling, incorporate the Titac North area into the existing inferred mineral resource evaluation and assess the potential for V-Ni-Co-PGE mineralization. Program parameters will be as follows:

• Holes planned: six to seven diamond core holes;
• Target depths: 400 to 600 metres;
• Total planned drilling: 2,500 to 3,000 metres;
• Average hole spacing: approximately 100 metres;
• Drill configuration: optimized infill drilling proximal to historical drilling to provide sufficient coverage to generate a Ti-Cu-V resource addition to the current Titac South MRE.

Key program elements:

• Drill hole optimization: APEX Geoscience Ltd. has reviewed drilling locations and designed methods to advance the planned drilling to incorporate the MRE block model. This work prioritizes efficient allocation of drilling metres and cost while selecting locations intended to maximize the potential for potential resource expansion.
• Regulatory: The 14 drill sites included in the company's exploration plan have been fully permitted by St. Louis County. The authorized exploration plan extends through April 1, 2028, providing the company with flexibility to evaluate results from the first six phase 2 holes, and prioritize follow-up drilling, additional studies and data collection.
• Execution: Logistics and planning are advanced. The program will be executed on a phased basis utilizing a Cascade sonic drill rig to set casing and a Foraco rig for diamond drilling, with both anticipated to start early to mid-October, 2026.
• Technical advancement: Downhole geophysical surveys will be conducted, with the aim of improving confidence in structural interpretation and to assist with future targeting.
• Dual-purpose drilling: All drill holes are designed to serve as multifunctional holes to provide data for geologic, hydrogeologic and geophysical data to further advance the technical foundation and evaluate the potential for resource expansion. This approach is also intended to support baseline data collection for future permitting and engineering studies.
• Assaying and metallurgical planning: Systematic multielement assaying will be completed to evaluate potential metal contributions from V-Ni-Co-PGEs. Metallurgical studies are planned as part of the broader technical program.
• Exploration potential: Ability to drill a new exploration target at Titac East, supported by the effectiveness of geophysical inversion modelling as a targeting tool for mineralized oxide ultramafic intrusions (see news release dated Sept. 10, 2026).
• 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.

Technical merit

The program benefits from Titac's Ti-Cu (titanium-copper) mineralization hosted in well-defined oxide ultramafic intrusions, which is supported by existing geological modelling. Combined with downhole geophysics and dual-purpose hydrogeology holes, the campaign is structured to advance both resource confidence and future technical and permitting readiness.

Titac South hosts a pit-constrained MRE with an effective date of Sept. 18, 2024, as reported in the independent National Instrument 43-101 technical report, titled "Technical Report and Mineral Resource Estimate for the South Contact Zone Project, St. Louis County, Minnesota, USA," available under the company's profile on SEDAR+.

Highlights of this report include:

• Data verification has been completed by a qualified person through a site visit and sampling, historical assay and certificate checks, a review of the resource block model, and update of the MRE for titanium at the Titac South prospect:
  • 45.1 million tonnes at 15 per cent TiO2;
• Verification of historical drilling, assays and results reported for Cu, Ni and PGEs at each of the four prospects; Wyman-Siphon, Skibo, Titac and Boulder included in the property:
  • 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.

Further notes on the mineral resource estimate:

• The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant issues.
