VANCOUVER, BC / ACCESS Newswire / February 17, 2026 / Green Bridge Metals Corporation (CSE:GRBM)(OTCQB:GBMCF)(FWB:J48)(WKN: A3EW4S) ("Green Bridge" or the "Company") is pleased to announce that it is advancing long-lead technical and operational work in preparation for a Phase 1 diamond drilling program planned for the second half of 2026 at its flagship Serpentine Copper-Nickel Project ("Serpentine" or the "Project"), located in St. Louis County, Minnesota, U.S.A. (Figure 1).
Serpentine is a large, open-pit style copper-nickel sulphide system in the Duluth Complex, located immediately adjacent to the NewRange Copper Nickel's ("NewRange") NorthMet and Sunrise deposits (Figure 2). The Company believes Serpentine's scale, grade, geometry and strategic location make it one of the most compelling copper and other critical minerals development opportunities in the Duluth Complex, particularly with copper and nickel prices at or near multi-year highs. Serpentine hosts an Inferred Mineral Resource Estimate ("MRE") of 279.9 million tonnes at 0.37% Cu, 0.12% Ni, and 0.007% Co (0.53% CuEq), with an additional Indicated 21.6 million tonnes at 0.46% Cu and 0.16% Ni (0.69% CuEq), as disclosed in the Company's NI 43-101 Technical Report ("Technical Report") dated July 14, 2025, a copy of which may be obtained under the Company's profile at www.sedarplus.ca1.
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.
The Phase 1 program is designed to achieve three objectives:
Test viability of the existing MRE, which, as noted above, is currently based on both indicated and inferred resources1 (Figure 3).
Test the overall copper-equivalent grade by examining the potential for indications of Platinum Group Metals ("PGM") and cobalt ("Co").
Position the Company toward completing a Preliminary Economic Assessment ("PEA") in respect of Serpentine within the next 18 months.
PROGRAM OVERVIEW
Planned Drilling: Phase 1 drilling planned for H2 2026: approximately 6 to 10 diamond core holes totaling ~2,000 to 2,500 meters.
Permitting: the Company is currently working with the Minnesota Department of Natural Resources on permitting of six new drill sites.
Execution Readiness: logistics and planning are advanced, with the Company targeting one rig for Phase 1 with Foraco, which are currently drilling at the Company's Titac Project.
Planned Drilling Depths: generally consistent with historical drilling (approximately 90 to >305m).
Technical Advancement: Down-hole geophysical surveys will be conducted, with the aim of improving confidence in structural interpretation, directing future exploratory drilling, and reducing uncertainty in targeting.
Dual-purpose Drilling: one or more holes may be designed to support hydrogeological monitoring following core recovery, providing a permitting and baseline study advantage. This approach is intended to support baseline data collection for future permitting and engineering studies.
Sampling: full multi-element assaying will be conducted, with the aim of improving CuEq and NSR reporting.
Systematic multi-element assaying and metallurgy planning: to evaluate potential for Copper Equivalent grade ("CuEq") upside through the potential inclusion of PGMs and cobalt, which are not included in the current MRE.
Strong technical de-risking advantage: shallow, low-strip geometry supported by geological modeling, plus downhole geophysical surveys and select dual-purpose core holes to be used as hydrogeology monitoring wells in support of future engineering and permitting work.
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.
