CANADA NICKEL ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT FOR PREVIOUSLY ANNOUNCED MANN CENTRAL AND MANN WEST INITIAL RESOURCES

Canada Nickel Company Inc. has filed on SEDAR+ an independent technical report prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, supporting the initial mineral resource estimate for its Mann nickel sulphide project, which consists of the Mann West and Mann Central properties and which contains the Mann West nickel-copper-palladium-platinum deposit and the Mann Central nickel-cobalt-palladium-platinum deposit -- together the Mann deposits.

The Mann project, located about 40 kilometres northeast of Timmins, Ont., is wholly owned by East Timmins Nickel Ltd., of which Canada Nickel owns 80 per cent and Noble Mineral Exploration Inc. owns 20 per cent. 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 (Canadian Institute of Mining, Metallurgy and Petroleum) Definition Standards on Mineral Resources and Reserves (2014) and CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2019).

Mark Selby, chief executive officer 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 on SEDAR+.
