VANCOUVER, BC / ACCESS Newswire / July 16, 2025 / Green Bridge Metals Corporation (CSE:GRBM)(OTCQB:GBMCF)(FWB:J48, WKN:A3EW4S) ("Green Bridge" or the "Company") is pleased to announce positive results from a core sampling campaign at the Skibo prospect ("Skibo"), located within the Company's south contact zone properties along the basal contact of the Duluth Intrusion, north of Duluth, Minnesota (the "South Contact Zone Properties"). The core sampling results include intercepts of 0.28% Cu and 0.15% Ni, over 153 meters (m) to include 3.1m at 1.6% Cu, 0.4% Ni, and 18.3 parts per million (ppm) Platinum Group Elements (PGE) (Figure 1) (Table 1). These new assay results from Skibo demonstrate the potential for both bulk tonnage and high-grade copper nickel systems to exist at Skibo. In addition, significant PGE and Cobalt mineralization was encountered in the unsampled drill core pointing to the potential for valuable by-products in the mineralized system. The initial results of the historical core sampling program warrant a continuation of the program to define the extent of the mineralized system(s) and development of drill targets with the goal of defining a resource at Skibo.
Message from David Suda CEO:
"We continue to be impressed by the South Contact Zone Properties. At Skibo, Green Bridge has discovered newly defined mineralization with 153m of approximately 0.6% CuEq from surface. The Skibo prospect is only one of four prospective properties with exceptional exploration and development potential. By adding length to the identified well mineralized zones at Skibo, we will pursue the extent of potential thickness at these zones. As we only begin to scratch the surface of the potential, the zones look to be significant and rich with metals including Copper, Nickel, PGEs, Cobalt and Titanium. We look forward to more results from Skibo as the program continues."
The goal of the 2025 core sampling program has been to evaluate whether high grade, massive sulphide veins are associated with a larger interval of lower grade, but still economic, copper and nickel grades and thus far the thesis is proving valid at Skibo. Results for 877m of previously unsampled drill core have been recently received from the assay lab and incorporated with historical assay data for the drill holes. The new, cumulative results have defined substantial grade and interval lengths in comparison to previously unpublished results. New sampling protocol has also included both a full trace element and whole rock analysis which provides valuable information for future exploration vectoring as well as metallurgical consideration. The addition of whole rock analysis provides valuable data on the existence of other critical minerals such as titanium dioxide (TiO2) and Cobalt at Skibo. Cobalt in drilling appears to be another value driver at Skibo with a 54.2m interval of 1982.6 ppm Co, in addition to 0.26% Cu, and 0.15% Ni, at the surface. Though the data is incomplete downhole, it is apparent from the new whole rock data that Oxide Ultramafic Intrusions (OUI), which typically contain substantial TiO2 and vanadium mineralization, are present in the near surface at Skibo and results of only a portion of the drilling contains intercepts of 51.5m at 4.2% TiO2 that includes 22.5m of 0.09% V2O5. Intercepts of massive, net-textured, and disseminated copper and nickel mineralization over tens to hundreds of meters is evidence that the mineralization at Skibo justifies continued attention by the Company (Figure 2).

The results of integrating assays over the entirety of historically drilled holes, as well as developing a model for the occurrence of mineralization in association with host intrusions and footwall sediments are together providing a strong foundation to understanding the geologic controls on all types of mineralization at Skibo. The technical team believes that there are two horizons for copper and nickel mineralization; one in the near surface, associated with OUI type magmatic bodies and one deeper, just above the contact with the Virginia Formation sediments, hosted in troctolitic intrusions. It also appears that there may be a discontinuous zone of massive sulphide veins between the upper and lower ore zones. This initial concept will continue to be modelled and tested as the core sampling program continues.

QUALITY ASSURANCE, QUALITY CONTROL AND QUALIFIED PERSONS
Please see the technical report entitled "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 prepared by independent "Qualified Persons" (as that term is defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101")) Michael B. Dufresne (P. Geol, P. Geo), Andrew J. Turner (P. Geol, P. Geo), Fallon T. Clarke (P.Geo) and Christian Bohm (P.Geo) for all historical assay information as well as information on the quality assurance and quality control ("QA/QC"), data verification, analytical and testing procedures at Skibo, part of the South Contact Zone Properties. The laboratory used for all historical data 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.
The Company's drill core samples were collected at 3.1m intervals with the exception of one core hole (SK09-03)which was sampled at 1.5m intervals. Sampling was conducted following industry standards and best practices. All new samples were submitted to Activation Labs in Thunder Bay, Ontario, an independent, commercial, assay lab, for geochemical analysis. The analyses used in this analytical program include fire assay with Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) analysis for gold and platinum group elements, sodium peroxide fusion analysis with analysis by ICP-OES was used to report all trace elements, and whole rock chemical composition was analyzed using a Lithium Metaborate fused disc with analysis by X-ray Fluorescence (XRF). Measures to ensure QA/QC of assay and analytical results include inserting assay standards certified for copper and nickel mineralization, or a certified blank every 6.1m. All data was reviewed for quality using comparison of results to QA/QC standards and using a pass/fail criteria of 3 standard deviations. All QA/QC standards and blanks passed the verification criteria.
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. Drill intersections have been independently selected and drill composites have been independently calculated by the Company.
