  • Exploration Target of an additional 0.5-1.0 billion tonnes grading0.20-0.22% nickel

• Mann West is the third of eight new nickel resources expected to bepublished in 2025

TORONTO, June 11, 2025 - CanadaNickel Company Inc. (" Canada Nickel " or the " Company ") (TSX-V:CNC) (OTCQB:CNIKF) today announced an initial mineral resource estimate (the“Mineral Resource Estimate” or “MRE”) for its Mann West NickelSulphide Project (“Mann West”) near Timmins, Ontario. Mann West is wholly owned by East Timmins Nickel Ltd. ofwhich Canada Nickel owns 80% and Noble Mineral Exploration Inc. owns20%.

The Mann West Nickel Sulphide Project is located just 21 kilometreseast of the Company’s Crawford Nickel Sulphide Project(“Crawford”) and is more than twice the size of Crawford based onthe outline of its geophysical target of 3.4 square kilometres. Thearea of the geophysical target covered by the Mann West resourcerepresents approximately 40% of the total target area. The Mann Westproject is accessible year-round.

Mark Selby, CEO of Canada Nickel said, “Mann West marks asignificant milestone with today’s announcement, demonstrating aresource that surpasses the size and scale of our initial Crawfordresource, and that validates our belief in the potential of theTimmins Nickel District. With a target footprint more than doubleCrawford’s, Mann West is just the third of eight new mineralresources we expect to announce by the end of 2025, including two morethis month.”

Mann West Mineral ResourceEstimate

For the initial Mineral Resource Estimate, a total of 16,833 metres ofcore drilling in 37 drill holes were utilized to calculate the MannWest Resources in two categories as provided in Table 1. IndicatedResources totalled 406 million tonnes grading 0.23% nickel, for atotal of 0.95 million tonnes of contained nickel and InferredResources totalled 599 million tonnes grading 0.22% nickel, for atotal of 1.31 million tonnes of contained nickel. The approximatedimensions of the resource are 1.9 kilometres long, 800 metres wide,extending to 500 metres deep and remaining open to the northwest andat depth. An additional 0.5 – 1.0 billion tonnes grading between0.20% and 0.22% nickel remain as an Exploration Target, pendingfurther drilling. This Exploration Target is based on core drilling bythe Company, the geophysical survey on the Project, and theunderstanding and calculation of the current MRE. Within the resource,a PGM Zone containing an Indicated resource of 7.0 million tonnesgrading 0.422 g/t palladium + platinum and an Inferred resource of 7.7million tonnes grading 0.411 g/t palladium + platinum.

The Exploration Target was derived by modelling the identified nickelsulphide mineralization within the current estimation envelope butoutside of the current Mineral Resource Estimate area.

The volume of the modelled Exploration Target area determines thepotential tonnage statement in the Exploration Target. The grade rangegiven in the Exploration Target is determined with consideration tothe drill core results within the modelled Exploration Target area,consideration of the geological setting in a well understood nickeldeposit type where grades are observed and well understood, and basedon the experience of the Company and the Qualified Persons. Thepotential tonnages and grades are conceptual in nature and are basedon drill holes and geophysical results that define the approximatelength, thickness, depth and grade of the Exploration Target. Therehas been insufficient exploration to define a current mineral resourceand the Company cautions that there is a risk that further explorationwill not result in the delineation of a current mineral resource.

Drilling at Mann West was completed in 2023 and 2024. The 2024campaign successfully completed the goal of infilling previoussections to allow for the definition of an initial mineral resourceestimate, gain understanding on the geology of the deposit, as well assystematically collecting samples for mineralogical analysis that havestarted to help define the potential of nickel recovery (see May 13,2024 news release).

The Mann West Mineral Resource Estimate was prepared by Caracle CreekInternational Consulting Inc. in accordance with CIM Estimation ofMineral Resources & Mineral Reserves Best Practice Guidelines(2019) and CIM Definition Standards for Mineral Resources &Mineral Reserves (2014). A Technical Report in support of the MineralResource Estimate will be filed on SEDAR+ ( www.sedarplus.ca ) within 45 days of this newsrelease.

*Totals may not add due to rounding.

Notes to Table 1 and Table 2:

1. The independent Qualified Person forthe Mineral Resource Estimate (“MRE”), as defined by NationalInstrument 43-101 (“NI 43-101”), is Dr. Scott Jobin-Bevans(P.Geo., PGO #0183), of Caracle Creek International Consulting Inc.The effective date of the Mineral Resource Estimate is May 30,2025.

2. The quantity and grade of reportedInferred Resources in this MRE are uncertain in nature and there hasbeen insufficient exploration to define these Inferred Resources asIndicated or Measured. However, it is reasonably expected that themajority of Inferred Mineral Resources could be upgraded to IndicatedMineral Resources with continued exploration.

3. A cut-off grade of 0.10% Ni was usedto define potentially economic material for inclusion within the MRE.Cut-offs were determined on the based on core assay geostatistics anddrill core lithologies for the deposit, and by comparison to analogousnickel deposit types.

4. Geological and block models for theMRE used data from a total of 37 surface drill holes, completed byCanada Nickel in 2023 and 2024. The drill hole database was validatedprior to resource estimation and QA/QC checks were made usingindustry-standard control charts for blanks, core duplicates andcommercial certified reference material inserted into assay batches byCanada Nickel and by comparison of umpire assays performed at a secondlaboratory.

5. Estimates have been rounded to twosignificant figures.

6. The MRE was prepared following theCIM Estimation of Mineral Resources Mineral Reserves Best PracticeGuidelines (November 29, 2019) and the CIM Definition Standards forMineral Resources Mineral Reserves (May 19, 2014).

7. The geological model as applied tothe MRE comprises three mineralized domains hosted by variablyserpentinized ultramafic rocks: a relatively higher-grade core(dunite), a lower grade (peridotite), and a PGE-rich pyroxenite“reef”. Individual wireframes were created for each domain inLeapfrog Geo 2024.1 software.

8. A 20 m x 20 m x 15 m block model wascreated, and samples were composited at 7.5 m intervals. Gradeestimation from drill hole data was carried out for Ni, Co, Fe, Cr, S,Pd and Pt using the Ordinary Kriging interpolation method in Isatis2024.04 software.

9. The MRE has been constrained by aconceptual pit envelope that was developed using the followingoptimization parameters. Metal prices used were US$21,000/t nickel,US$40,000/t cobalt, US$325/t iron, US$3,860/t chromium, US$1,350/ozpalladium, and US$1,150/oz platinum. Different pit slopes were usedfor each layer (in degrees): 9.5 in overburden, and 40.0 inmineralized rock, and 45 in waste rock. Exchange rate utilized wasUS$/C$ at $0.76. Mining costs utilized different values for overburden(clay, gravel), and rock mining, ranging from C$1.47 to C$3.53/tmined. Processing costs and general and administration costs for a 120ktpd operation (similar to the ultimate scope of Crawford) wereC$8.30/t. Based on the range of grade and ratio of sulphur to nickel,calculated recovery averages 45% for Ni, 7% for Co, 56% for Fe, 29%for Cr 45% for Pd and 28% for Pd.

10. Grade estimation was validated bycomparison of input and output statistics (Nearest Neighbour andInverse Distance Squared methods), swath plot analysis, cross-plots ofdeclustered samples against the nearest OK estimate, and by visualinspection of the assay data, block model, and grade shells incross-sections.

11. Density estimation was carried outfor the mineralized domains using the Ordinary Kriging interpolationmethod, based on 1,740 specific gravity measurements collected duringthe core logging process, using the same block model parameters of thegrade estimation. As a reference, the average estimated density valuewithin dunite is 2.64 g/cm (t/m ), while the peridotitedomain yielded an average of 2.74 g/cm (t/m ), and the PGE “reef” domain anaverage of 3.05 g/cm (t/m ).
