Canada Nickel Announces Filing of NI 43-101 Technical Report for Previously Announced Mann Central and Mann West Initial Resources

TORONTO, July 29, 2025 – Canada Nickel Company Inc. (“Canada Nickel” or the “Company”) (TSXV: CNC) (OTCQB: CNIKF) today announced that the Company has filed on SEDAR+ an independent technical report (the “Report”) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) supporting the initial mineral resource estimate for its Mann Nickel Sulphide Project (the “Mann Project”) which consists of the Mann West and Mann Central Properties and which contain the Mann West Ni-Co-Pd-Pt Deposit and the Mann Central Ni-Co-Pd-Pt Deposit – together the Mann Deposits.

The Mann Project, located about 40 kilometres northeast of Timmins, Ontario, is wholly owned by East Timmins Nickel Ltd. of which Canada Nickel owns 80% and Noble Mineral Exploration Inc. owns 20%. There are no material differences in the Report from those results disclosed in the Company’s news releases dated June 11, 2025, and July 15, 2025.  The Mineral Resource Estimate for the Mann Deposits, effective as of July 15, 2025, was prepared following the CIM Definition Standards on Mineral Resources and Reserves (2014) and CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2019).

Mark Selby, CEO of Canada Nickel said, “We have now published six of nine resources with over 9.2 million tonnes of Measured and Indicated nickel and 9.5 million tonnes of Inferred nickel. Three additional resources are expected to be published by end of 2025. The size and scale of the Mann West and Mann Central resource, is significantly larger than the initial Crawford resource, and validates our belief in the potential of the Timmins Nickel District.  We look forward to continuing to demonstrate the potential of this world class district.”

The Report, dated July 28, 2025, with an effective date of July 15, 2025, is titled, “National Instrument 43-101 Mineral Resource Estimates and Technical Report on the Mann West and Mann Central Ni-Co-Pd-Pt Deposits, Mann Nickel Sulphide Project, Timmins Nickel District, Ontario, Canada.” The Report was prepared for Canada Nickel by Caracle Creek International Consulting Inc. and can be found under the Company’s issuer profile at www.sedarplus.com.
