GeoRedox and Canada Nickel Launch First-of-its-kind Geologic Hydrogen Program at Crawford Nickel Project in Timmins, Ontario

Press Release

Highlights:

⦁ MOU signed to develop first stimulated geologic hydrogen well at Crawford Nickel Project, Timmins, Ontario

⦁ Zero-carbon hydrogen to be produced from natural chemical reactions in ultramafic rock

⦁ Advances Canada Nickel’s Zero-Carbon Industrial Cluster vision for the Timmins Nickel District

BOSTON, TORONTO – May 20, 2026 – GeoRedox Corporation (“GeoRedox”) and Canada Nickel Company Inc. (“Canada Nickel” or the “Company”) (TSXV: CNC) (OTCQX: CNIKF) are pleased to announce that they have signed a Memorandum of Understanding (“MOU”) launching a partnership to develop the world’s first stimulated geologic hydrogen well on the site of Canada Nickel’s Crawford Nickel Project near Timmins, Ontario.

The project will test GeoRedox’s proprietary technology for producing zero-carbon hydrogen from ultramafic rock formations – the same geology that underlies Canada Nickel’s twenty-plus projects in the Timmins Nickel District – and represents a foundational step toward a zero-carbon industrial cluster in Northeast Ontario.

Robert Stoner, President of GeoRedox said: “Hydrogen is used extensively in metals production, which makes GeoRedox a natural partner to the mining industry. In Canada Nickel we’re delighted to have partnered with a mining company that shares our commitment to industrial decarbonization and environmental stewardship – and our sense of urgency. Crawford gives us the ideal real-world setting to validate our technology alongside a world-class mining operation. The opportunity to develop a project with Canada Nickel in a well-developed industrial region with extensive infrastructure is truly exciting.”

Mark Selby CEO of Canada Nickel said, “The ultramafic rock that hosts our Crawford deposit and twenty-plus projects across the Timmins Nickel District is precisely the geology GeoRedox’s technology is designed for. This partnership brings us a significant step closer to a Zero-Carbon Industrial Cluster in Northeast Ontario – one that converts our concentrates into finished critical mineral products including nickel, chromium and cobalt, while leveraging the region’s significant carbon storage capacity.”

GeoRedox will fund the demonstration program in full. Canada Nickel will contribute site access, rock samples, technical expertise, data, and other resources necessary for project planning and implementation at Crawford. The demonstration is the first phase of a program that, if successful, has the potential to provide a large-scale, carbon-free hydrogen supply for a zero-carbon industrial cluster in the Timmins Nickel District.

Once constructed and in operation, Crawford, which is located in Ontario’s Critical Minerals Corridor, is expected to rank among the Western world’s largest nickel sulphide projects and among the world’s

lowest-carbon nickel operations. The project’s ultramafic geology – the same rock type that hosts GeoRedox’s target formations globally – makes it a natural site for the demonstration program.
