TORONTO, June 11, 2025 - Canada Nickel 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 Nickel Sulphide Project ("Mann West") near Timmins, Ontario. Mann West is wholly owned by East Timmins Nickel Ltd. of which Canada Nickel owns 80% and Noble Mineral Exploration Inc. owns 20%.

The Mann West Nickel Sulphide Project is located just 21 kilometres east of the Company's Crawford Nickel Sulphide Project ("Crawford") and is more than twice the size of Crawford based on the outline of its geophysical target of 3.4 square kilometres. The area of the geophysical target covered by the Mann West resource represents approximately 40% of the total target area. The Mann West project is accessible year-round.

Mark Selby, CEO of Canada Nickel said, "Mann West marks a significant milestone with today's announcement, demonstrating a resource that surpasses the size and scale of our initial Crawford resource, and that validates our belief in the potential of the Timmins Nickel District. With a target footprint more than double Crawford's, Mann West is just the third of eight new mineral resources we expect to announce by the end of 2025, including two more this month."

Mann West Mineral Resource Estimate

For the initial Mineral Resource Estimate, a total of 16,833 metres of core drilling in 37 drill holes were utilized to calculate the Mann West Resources in two categories as provided in Table 1. Indicated Resources totalled 406 million tonnes grading 0.23% nickel, for a total of 0.95 million tonnes of contained nickel and Inferred Resources totalled 599 million tonnes grading 0.22% nickel, for a total of 1.31 million tonnes of contained nickel. The approximate dimensions of the resource are 1.9 kilometres long, 800 metres wide, extending to 500 metres deep and remaining open to the northwest and at depth. An additional 0.5 – 1.0 billion tonnes grading between 0.20% and 0.22% nickel remain as an Exploration Target, pending further drilling. This Exploration Target is based on core drilling by the Company, the geophysical survey on the Project, and the understanding and calculation of the current MRE. Within the resource, a PGM Zone containing an Indicated resource of 7.0 million tonnes grading 0.422 g/t palladium + platinum and an Inferred resource of 7.7 million tonnes grading 0.411 g/t palladium + platinum.

The Exploration Target was derived by modelling the identified nickel sulphide mineralization within the current estimation envelope but outside of the current Mineral Resource Estimate area.

The volume of the modelled Exploration Target area determines the potential tonnage statement in the Exploration Target. The grade range given in the Exploration Target is determined with consideration to the drill core results within the modelled Exploration Target area, consideration of the geological setting in a well understood nickel deposit type where grades are observed and well understood, and based on the experience of the Company and the Qualified Persons. The potential tonnages and grades are conceptual in nature and are based on drill holes and geophysical results that define the approximate length, thickness, depth and grade of the Exploration Target. There has been insufficient exploration to define a current mineral resource and the Company cautions that there is a risk that further exploration will not result in the delineation of a current mineral resource.

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

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

Notes to Table 1 and Table 2:

1. The independent Qualified Person for the Mineral Resource Estimate ("MRE"), as defined by National Instrument 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 reported Inferred Resources in this MRE are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured. However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

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

4. Geological and block models for the MRE used data from a total of 37 surface drill holes, completed by Canada Nickel in 2023 and 2024. The drill hole database was validated prior to resource estimation and QA/QC checks were made using industry-standard control charts for blanks, core duplicates and commercial certified reference material inserted into assay batches by Canada Nickel and by comparison of umpire assays performed at a second laboratory.

5. Estimates have been rounded to two significant figures.

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

7. The geological model as applied to the MRE comprises three mineralized domains hosted by variably serpentinized 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 in Leapfrog Geo 2024.1 software.

8. A 20 m x 20 m x 15 m block model was created, and samples were composited at 7.5 m intervals. Grade estimation from drill hole data was carried out for Ni, Co, Fe, Cr, S, Pd and Pt using the Ordinary Kriging interpolation method in Isatis 2024.04 software.

9. The MRE has been constrained by a conceptual pit envelope that was developed using the following optimization 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/oz palladium, and US$1,150/oz platinum. Different pit slopes were used for each layer (in degrees): 9.5 in overburden, and 40.0 in mineralized rock, and 45 in waste rock. Exchange rate utilized was US$/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/t mined. Processing costs and general and administration costs for a 120 ktpd operation (similar to the ultimate scope of Crawford) were C$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 by comparison of input and output statistics (Nearest Neighbour and Inverse Distance Squared methods), swath plot analysis, cross-plots of declustered samples against the nearest OK estimate, and by visual inspection of the assay data, block model, and grade shells in cross-sections.

11. Density estimation was carried out for the mineralized domains using the Ordinary Kriging interpolation method, based on 1,740 specific gravity measurements collected during the core logging process, using the same block model parameters of the grade estimation. As a reference, the average estimated density value within dunite is 2.64 g/cm (t/m ), while the peridotite domain yielded an average of 2.74 g/cm (t/m ), and the PGE "reef" domain an average of 3.05 g/cm (t/m ).
