Green Bridge Metals selects Foraco for Phase 1 drilling at Serpentine

VANCOUVER, BC / ACCESS Newswire / July 2, 2026 / Green Bridge Metals Corporation (CSE: GRBM )(OTCQB: GBMCF )(FWB: J48 ,WKN: A3EW4S ) (" Green Bridge " or the " Company ") is pleased to announce that it has received approval of its exploration plan from the Minnesota Department of Natural Resources (DNR) for its flagship Serpentine Copper-Nickel Project (" Serpentine " or the " Project ") in St. Louis County, Minnesota. The Company has also selected Foraco International (" Foraco ") to conduct a minimum of 1,640 meters of diamond core drilling as part of the planned Phase 1 program. Foraco will mobilize to the site to execute the program, building on their successful ongoing work at the Company's Titac Project.

This marks a significant step forward in advancing exploration at Serpentine, targeting high-priority zones within this large-scale copper-nickel-platinum group elements system. CEO David Suda stated: " We are excited to secure the DNR approval and select Foraco once again to commence our Phase 1 drilling at Serpentine. Serpentine already hosts significant Inferred Mineral Resources and Indicated Mineral Resources within one of North America's premier copper-nickel districts.

Our objective is to systematically advance the project through additional drilling, resource refinement and metallurgical work designed to improve our understanding of the deposit and support future technical studies. We believe disciplined technical work is how value is created in the mineral development cycle - by reducing uncertainty, increasing confidence in the resource, and positioning an asset for future development decisions. " Serpentine Project Summary Serpentine hosts significant pit-constrained Inferred Mineral Resources and Indicated Mineral Resources within the Duluth Complex in St. Louis County, northern Minnesota.

As disclosed in the technical report entitled " Technical Report and Mineral Resource Estimate for the Serpentine Project, St. Louis County, Minnesota, USA " with an effective date of July 14, 2025, prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (" NI 43-101 "), Serpentine has an Inferred Mineral Resource Estimate of 279.9 million tonnes at 0.37% Cu, 0.12% Ni, and 0.007% Co, using a US$10.25/tonne NSR cut-off which includes 21.6 million tonnes in the Indicated Mineral Resource category grading 0.46% Cu, 0.16% Ni, and 0.014% Co, using a US$10.25/tonne NSR cut-off. Cautionary Note Regarding Mineral Resources: Inferred Mineral Resources have a lower level of confidence than that applying to Indicated Mineral Resources and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

However, there is no certainty that such upgrading will occur or that the Inferred Mineral Resources will ever be converted into Mineral Reserves. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

The approved Phase 1 program is designed to advance the Project in a disciplined and technically focused manner. Drilling, which is expected to commence in August 2026, will focus on areas where additional data may support increased geological confidence in portions of the existing Mineral Resource. In parallel, the Company plans to undertake metallurgical test work to better understand potential processing characteristics and recovery pathways.

The objective of this work is to expand the technical dataset, support future resource updates where warranted, and position the Project for future scoping-level studies, subject to results. Drilling is expected to test and expand known mineralization, with results to inform future resource updates and development planning. The Company continues to work closely with regulators and stakeholders to ensure responsible exploration practices.
