Green Bridge Metals Corporation (OTCQB: GBMCF), also referenced as Green Bridge Metals Corp., is a Canadian-based mineral exploration company in the basic materials sector. The company focuses on acquiring and advancing critical mineral and battery metal rich assets, with a particular emphasis on copper, nickel, cobalt, platinum group elements (PGE), titanium and vanadium. Its principal exploration activities are centered on projects in North America, especially within Minnesota’s Duluth Complex and the broader Mesabi Range mining district, as well as the Chrome-Puddy project in Ontario, Canada.

Core Focus and Exploration Strategy

Green Bridge Metals describes itself as an exploration company focused on the acquisition and development of critical mineral rich assets. According to multiple company news releases, its strategy is to build a portfolio of projects that are prospective for bulk-tonnage and high-grade copper-nickel sulphides and associated critical metals. The company highlights the importance of these metals for applications such as the clean energy transition and national strategic supply, and positions its projects as potential contributors to North American supply chains for copper, nickel, cobalt and other critical minerals.

The company has repeatedly emphasized the development of the South Contact Zone / South Contact District along the basal contact of the Duluth Intrusion/Complex, north of Duluth, Minnesota. Across several releases, Green Bridge states that these properties contain bulk-tonnage copper-nickel and titanium-vanadium mineralization hosted in ultramafic to oxide ultramafic intrusions, with exploration targets for:

• Bulk-tonnage nickel (Ni) mineralization
• High-grade Ni-Cu-PGE magmatic sulphide mineralization
• Titanium and titanium-vanadium in ilmenite

Key Projects and Properties

Based on the company’s disclosures, Green Bridge Metals is advancing several key projects:

South Contact Zone / South Contact District (Minnesota, USA)
Green Bridge describes the South Contact Zone (also referred to as the South Contact District or South Contact Zone Properties) as a large exploration portfolio along the basal contact of the Duluth Intrusion/Complex, north of Duluth, Minnesota. Within this portfolio, the company identifies multiple prospects, including:

• Titac / Titac South / Titac North – The Titac property is located in St. Louis County, Minnesota, within the Duluth Complex. The company reports that Titac South hosts an Inferred Mineral Resource for titanium dioxide (TiO₂) mineralization, documented in a NI 43-101 compliant 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. Green Bridge notes that Titac South contains titanium-vanadium mineralization in ilmenite and that a portion of the property, known as Titac South, has an inferred mineral resource estimate for TiO₂. The company also discloses that Titac South contains significant copper and vanadium that were not included in that mineral resource estimate, and that historical drilling at Titac North indicates mineralization of a similar order to Titac South, though Titac North does not yet have a mineral resource estimate.
• Skibo – Skibo is part of the South Contact Zone Properties along the basal contact of the Duluth Intrusion. Green Bridge has reported results from a core sampling campaign on historically drilled but previously unsampled core at Skibo. The company states that these results demonstrate the potential for both bulk-tonnage and high-grade copper-nickel systems, with additional cobalt, PGE and titanium dioxide mineralization identified in the system. The company notes that a significant portion of historical core at Skibo had been left unsampled and that new sampling and whole-rock analysis have revealed disseminated copper-nickel sulphide mineralization and oxide ultramafic intrusions containing TiO₂ and vanadium.
• Wyman-Siphon – Green Bridge refers to Wyman-Siphon as a property on trend with well-known copper-nickel deposits such as NorthMet, Mesaba and Maturi. The company cites a historical inferred mineral resource estimate for Wyman of approximately 47 million short tonnes grading 0.29% copper and 0.11% nickel, and clarifies that this estimate is historical, was not prepared in accordance with current NI 43-101 standards, and is treated as an historical resource that requires further work to be verified.
• Boulder – The company notes that historical drilling at the Boulder prospect indicates potential for TiO₂, V₂O₅, copper and minor nickel mineralization, with reported intervals that include titanium-vanadium in ilmenite and associated copper.

Across these South Contact Zone Properties, Green Bridge indicates that geophysical work, including VTEM airborne surveys and analysis of historical data, has identified geophysical signatures of additional oxidized ultramafic intrusions associated with copper-nickel-titanium-vanadium mineralization that remain underexplored.

Serpentine Project (Minnesota, USA)
Green Bridge Metals has entered into a letter of intent and subsequently a definitive agreement with Encampment Minerals Inc. to obtain an option to earn up to a 70% interest in the Serpentine Copper-Nickel Project, located in northern St. Louis County, Minnesota, approximately 5 km southeast of the town of Babbitt, in the Mesabi Range mining district. The company describes Serpentine as a large bulk-tonnage copper-nickel-PGE project hosted in magmatic sulphide mineralization within the Duluth Complex.

The company reports that Serpentine has a historical National Instrument 43-101 mineral resource estimate prepared on behalf of another issuer, with pit-constrained indicated and inferred mineral resources for copper and nickel, and a massive sulphide domain. Green Bridge notes that these historical estimates were prepared in conformity with CIM standards but are treated as historical in nature, and that a qualified person has not done sufficient work to classify the historical estimate as current mineral resources for Green Bridge. The company has since filed its own NI 43-101 Technical Report and Mineral Resource Estimate for the Serpentine Project, with an effective date of July 14, 2025, which outlines indicated and inferred mineral resources for copper, nickel and cobalt and describes a core massive sulphide domain.

Green Bridge emphasizes that Serpentine is located in a long-lived mining jurisdiction with access to regional infrastructure, including highways, rail access to Lake Superior ports via a private rail line, grid power and a skilled mining workforce. The company also references early metallurgical test work from a 2012 scoping study completed by Encampment Minerals Inc., which indicated high recoveries of copper and nickel using flotation, and notes that the deposit geometry is considered favourable for open-pit style development with potential for low strip ratios. The company positions Serpentine as a cornerstone asset in its portfolio.

Chrome-Puddy Project (Ontario, Canada)
In its discussion of 2024 milestones, Green Bridge highlights the Chrome-Puddy project in Ontario, Canada. The company reports that prospecting at the Chrome-Puddy ultramafic intrusion revealed widespread iron-nickel oxide mineralization with potential for bulk-tonnage nickel resources. It notes that grab and channel sampling have identified nickel mineralization over significant intervals and that these results, combined with VTEM airborne geophysical survey data, define large-scale conductors and drill targets. The company presents Chrome-Puddy as part of its broader focus on battery metal rich mineral assets.
