Star Metro - Green Bridge Metals Completes Re-Sampling of Historical Core Assay and Geophysics Data for Skibo Prospect

Key Highlights

• Disseminated Cu-Ni-PGM mineralization identified over intervals exceeding 200-400 metres in multiple historic holes

• High-grade massive and semi-massive sulfide intercepts spatially associated with mapped electromagnetic conductors

• Conductive anomalies interpreted to extend between two historic drill clusters, supporting potential system continuity

• Integrated geological and geophysical model establishes a repeatable targeting framework for future drilling

• Geological model enhanced through low-cost historic core sampling program (

Integrated Results Indicate Potential for a Coherent Mineralized System

The presence of massive and semi-massive Cu-Ni-PGM intervals at Skibo has been indicated by the resampling program of historical drill core. The goal of this program was to target unsampled intervals above and below historical assay intervals that report high-grade zones. Sampling of the historical drill core is expected to allow the Company to evaluate whether disseminated mineralization halos exist and to assess their spatial relationship to mapped electromagnetic conductors.

Results from the re-sampling work confirmed that massive sulfide veins occur within broader disseminated halos extending over substantial downhole lengths (Table 1). The highest-grade intercepts are spatially associated with mapped electromagnetic conductors, supporting the interpretation that these conductors represent mineralized sulfide trends rather than isolated occurrences. The Table of results shown below reflects significant intervals of mineralization in the core that integrates both the historical assay results with the new assay intervals completed by the Company (Table 2). This reflects a more complete picture of the extent and tenor of mineralization the historical drillhole dataset. For reports of the historical drill hole and assay data please see the Company's Technical Report titled, "Technical Report and Mineral Resource Estimate for the South Contact Zone Project, St Louis County, Minnesota, USA" with an effective date of September 18, 2024.

Geophysical Targeting

The relationship between mineralization and electromagnetic conductors establishes a repeatable, data-supported targeting methodology for future drill programs. Historical drill holes that are observed to have strong Cu-Ni-PGM mineralization are spatially correlated with mapped electromagnetic conductors (show as red lines on Figure 2). Where historical drill holes were observed to have modest Cu-Ni-PGMM mineralization, they are not spatially coincident with the electromagnetic conductors. Future exploration plans will focus on testing electromagnetic conductor trends and step-out targets between and beyond historic core holes.

District Context

Mineralization at Skibo occurs along the basal contact of the Duluth Complex, a geological setting that hosts several copper-nickel deposits in Minnesota. While exploration at Skibo remains at an early stage, the style of mineralization, presence of thick disseminated halos, and association with geophysical conductors are consistent with magmatic sulfide systems elsewhere in the district.

CEO Commentary

" These early results are encouraging and advance our understanding of Skibo, " said David Suda, President and CEO of Green Bridge Metals. This gives us a clear and disciplined path for further exploration. Skibo is emerging as a serious opportunity within our district portfolio. "

Quality Assurance and Quality Control

Geol, P. Geo), Andrew J Turner (P. Geol, P. Geo), Fallon T Clarke (P.Geo), Christian Bohm (P.Geo)) for all historical assay information as well as information on the QA/QC, data verification, analytical and testing procedures at the Skibo prospect, part of the South Contact Zone Project. The laboratory used for all historical data presented herein is ALS Minerals, which is independent of the Company. The laboratory used for all new assay data herein is Activation Labs, which is independent of the Company.

Green Bridge Metals exploration samples were collected following industry standards and best practices. All new samples were submitted to Activation Labs in Thunder Bay, Ontario for geochemical analysis. The analyses used in this analytical program include; fire assay with ICP-OES analysis for gold and platinum group metals, sodium peroxide fusion analysis with analysis by ICP-OES was used to report all trace elements, and chemical composition was analyzed using a Lithium Metaborate fused disc with analysis by XRF.

Lengths are drill intersections and not necessarily true widths. True widths cannot be consistently calculated for comparison purposes between holes because of the irregular shapes of the mineralized zones. The geological interpretations in this news release are solely those of the Company. The locations and distances highlighted on all maps in this news release are approximate.

Ajeet Milliard, Chief Geologist at Green Bridge Metals and a Qualified Person within the meaning of NI 43-101 is satisfied that the analytical and testing procedures used are standard industry operating procedures and methodologies, and has reviewed, approved and verified the technical information disclosed in this news release, including sampling, analytical and test data underlying the technical information.
