Highlights:

• Mann Central similar scale to InitialCrawford Nickel Project Resource:

  • Indicated Mineral Resource of 236.7 million tonnes grading 0.22%nickel containing 0.52 million tonnes of nickel.

  • Inferred Mineral Resource of 543.2 million tonnes grading 0.21% nickelcontaining 1.15 million tonnes of nickel.

  • Exploration Target of an additional 0.6-2.0 billion tonnes grading0.19 – 0.21% nickel.

TORONTO, July 15, 2025 - CanadaNickel Company Inc. (" Canada Nickel " or the " Company ") (TSX-V:CNC) (OTCQB:CNIKF) today announced initial mineral resource estimates (the“Mineral Resource Estimate” or “MRE”) for its Mann CentralNickel Sulphide Project (“Mann Central”), located 40 km northeastof Timmins, Ontario and its Texmont Nickel Sulphide Project(“Texmont”), located 36 km south of Timmins.  Canada Nickel owns80% of Mann Central through its interest in EastTimmins Nickel Ltd. (“East Timmins”), with the remaining 20% ofEast Timmins owned by Noble Mineral Exploration Inc. (“Noble”).Texmont is wholly owned by Canada Nickel through the Company’swholly owned subsidiary, Central Timmins Nickel Company Inc.(“Central Timmins”). Mark Selby, CEO of Canada Nickel said,“We are very pleased with these two new resources and even moreexcited by the growing scale of the Timmins Nickel District with over9 million tonnes in each of the Measured & Indicated and Inferredcategories. Mann Central is a mineral resource with significant scaleand considerable potential for further testing in the future. Texmont,though a smaller target, has delivered strong results with meaningfulquantities of higher grade nickel. I look forward to advancingCrawford towards a year-end construction decision and to showcasingthe full potential of the Timmins Nickel District, with threeadditional mineral resource estimates to be published by year-end.”

Mann Central Mineral ResourceEstimate

The Mann Central Project is only 23 km east of the Company’sCrawford Nickel Sulphide Project (“Crawford”) and is more thantwice the size of Crawford based on the outline of its geophysicaltarget of 3.1 square kilometres. The area of the geophysical targetcovered by the Mann Central MRE represents approximately 40% of itstotal target geophysical area. Mann Central is accessible year-round.

For the initial MRE, a total of 12,563 metres of core drilling from 32drill holes were utilized to calculate the Mann Central mineralresources in two categories as summarized in Table 2. IndicatedMineral Resources total 237 million tonnes grading 0.22% nickel, for atotal of 0.52 million tonnes of contained nickel and Inferred MineralResources total 537 million tonnes grading 0.21% nickel, for a totalof 1.15 million tonnes of contained nickel. The approximate dimensionsof the Mann Central MRE are 2.4 kilometres long, up to 700 metreswide, extending to 500 metres deep, and remaining open in alldirections. An additional 0.6 – 2.0 billion tonnes grading between0.19% and 0.20% nickel remain as an Exploration Target, pendingfurther drilling. This Exploration Target is based on core drilling bythe Company, the geophysical survey on the Mann Central Project, andthe understanding and calculation of the current Mann Central MRE.

The Exploration Target was derived by modelling the identified nickelsulphide mineralization within the current estimation envelope butoutside of the current MRE area. The volume of the modelledExploration Target area determines the potential tonnage statement inthe Exploration Target. The grade range given in the ExplorationTarget is determined with consideration to the drill core resultswithin the modelled Exploration Target area, consideration of thegeological setting in a well understood nickel deposit type wheregrades are observed and well understood and based on the experience ofthe Company and the Qualified Persons. The potential tonnages andgrades are conceptual in nature and are based on drill holes andgeophysical results that define the approximate length, thickness,depth and grade of the Exploration Target. There has been insufficientexploration to define a current mineral resource and the Companycautions that there is a risk that further exploration will not resultin the delineation of a current mineral resource.

Drilling at Mann Central was conducted 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.

The Mann Central MRE was prepared by Caracle Creek InternationalConsulting Inc. and its sub-consultant L&M  Geociencias, inaccordance with CIM Estimation of Mineral Resources & MineralReserves Best Practice Guidelines (2019) and CIM Definition Standardsfor Mineral Resources & Mineral Reserves (2014). A TechnicalReport in support of the Mineral Resource Estimate will be filed onSEDAR+ ( www.sedarplus.ca ) within 45 days of this newsrelease.

Notes to Table 2:

1. The independent Qualified Person forthe MRE, as defined by National Instrument 43-101 – Standards ofDisclosure for Mineral Projects (“NI 43-101”), is Dr. ScottJobin-Bevans (P.Geo., PGO #0183), of Caracle Creek InternationalConsulting Inc. The effective date of the MRE is June 25,2025.

2. The quantity and grade of reportedInferred Mineral Resources in this MRE are uncertain in nature andthere has been insufficient exploration to define these InferredMineral Resources as Indicated or Measured. However, it is reasonablyexpected that the majority of Inferred Mineral Resources could beupgraded to Indicated Mineral Resources with continuedexploration.

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 basis of 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 32 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 using industry-standard control charts forblanks, core duplicates and commercial certified reference materialinserted into assay batches by Canada Nickel and by comparison ofumpire assays performed at a second laboratory.

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 two mineralized domains hosted by variablyserpentinized ultramafic rocks: a relatively higher-grade core(dunite), and a lower grade (peridotite). Individual wireframes werecreated for each domain in Leapfrog 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$3.00/tmined. Processing costs and general 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 39% for Ni, 10% for Co, 54% for Fe, 29%for Cr, 39% for Pd and 18% 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 1,270 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 2.66 g/cm (t/m ), while the peridotitedomain yielded an average of 2.74 g/cm (t/m ).
