Company Announcements

TORONTO , Aug. 5, 2025 /PRNewswire/ - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQB: CNIKF) today released its 2024 Environmental, Social and Governance (ESG) Report, showcasing continued progress across carbon storage innovation, Indigenous partnerships, local economic development, health and safety, and environmental stewardship. The report underscores Canada Nickel's growing role in Ontario's Critical Minerals Corridor and outlines the Company's strategy to responsibly supply the materials essential to Canada's clean energy transition and defense resilience.

"The milestones achieved in 2024 reflect the strength and vision of our team and the powerful model we're building with Indigenous Nations and communities across the Timmins Nickel District," said Mark Selby, CEO of Canada Nickel. "With major partnerships, a unique carbon storage solution, and strong support across the region, we are proud to be advancing nickel in a way that is inclusive, future-focused, and aligned with the goals of both the Governments of Ontario and Canada's critical minerals strategies."

Throughout 2024, Canada Nickel deepened its collaboration with Indigenous Nations, advanced low-carbon technologies, and reinforced its commitment to responsible development through transparent reporting and inclusive governance. The Company's efforts position it not only as a cleaner nickel producer than the industry standard, but as a trusted partner in shaping the next generation of sustainable mining in Canada.

"Indigenous partnerships and community stewardship are not a side project at Canada Nickel – they are embedded into how we operate," said Pierre-Philippe Dupont, Vice President of Sustainability. "We are building more than a mine; we are helping build a resilient, low-carbon critical minerals corridor that reflects the values of the communities we work with. From equity ownership and business partnerships to direct investment in local infrastructure, this is what inclusive growth looks like."
