NEWS RELEASE
Green Bridge Metals Obtains Exploration Drilling Plan Approval and Selects
Foraco for Phase 1 Diamond Core Drilling at Serpentine Copper-Nickel
Project, Minnesota, USA
Vancouver, Canada – 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 f uture 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 t echnical 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.

This positions Serpentine as a significant undeveloped copper -nickel project aligned with U.S. priorities
for domestic critical minerals supply. 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.

that certain events or conditions "may" or "will" occur. Forward -looking statements in this news release
include, but are not limited to, statements with respect to the timing and results of the planned drilling
program at the Serpentine Project; expectations regarding the Company’s relationship with Foraco; the
Company’s ability to advance the project through additional drilling, resource refinement and
metallurgical work ; potential future resource upgrades or expansions; and the Company’s plans for
further exploration, technical work and development of its Minnesota project portfolio. Forward-looking
information is based on a number of assumptions and factors considered reasonable by the Company as
of the date of this news release, including, without limitation, assumptions regarding: the accuracy of the
Company’s current geological mod els, Mineral Resource Estimates and technical information; the
continued validity of the exploration plan approval received from the DNR ; the ability of Foraco and the
Company’s other contractors, consultants and technical personnel to perform the planned work
programs as currently anticipated; the availability of equipment, personnel, services and supplies
required to carry out the planned drilling and technica l work; the Company’s ability to obtain and
maintain all required permits, approvals and authorizations; the availability of sufficient working capital
or financing on acceptable terms; stable market conditions and commodity prices; the absence of
material adverse changes in applicable laws, regulations, project parameters, access, environmental
conditions, community or stakeholder relations, or general economic and capital market conditions; and
that exploration and technical results will be consistent wit h management’s expectations. Although the
Company believes that the expectations reflected in such forward- looking statements are reasonable,
there can be no assurance that such expectations will prove to be correct. Forward- looking statements
