Canada Nickel Reports Continued Exploration Success

at Reid, Mann West and Deloro

Highlights

• Mann West – successful final three holes, Mann West initial resource to be published in June

o 0.33% nickel over 52 metres within 480 metres of 0.27% nickel in hole MAN24-65

• Reid – successful infill drilling program to support an updated resource by year-end 2025

o 0.27% nickel over 711 metres including 0.45% nickel over 39 metres within 0.37%

nickel over 120 metres in REI24-70

• Deloro – successful infill drilling with shallow overburden to support updated resource by

year-end 2025

o 0.38% nickel over 48 metres within 347 metres of 0.26% nickel in hole DEL24-35, with

mineralization starting at 6 metres below surface

TORONTO, May 28, 2025 – Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC)

(OTCQX: CNIKF) is pleased to announce additional exploration drilling results from the Reid, Mann West

and Deloro properties.

CEO Mark Selby said, “The Timmins Nickel District continues to deliver excellent exploration results from

Reid, Mann West and Deloro. We look forward to initial resources from three of our projects (Mann West,

Mann Central, and Texmont) in June 2025. The results from Reid continue to show impressive continuity

for both the overall mineralization and higher-grade zones, and Deloro continues to deliver excellent

intervals with shallow overburden. The results will support conversion of potential resources at both

projects, and we expect to publish updated resources by year-end 2025. I am excited by our ongoing and

clear demonstration of the potential of the Timmins Nickel District, with six resources to be published by

the end of June and three additional resources to be published through the remainder of 2025.”

Reid Project

Highlights:

• 0.27% nickel over 711 metres, including 0.45% nickel over 39 metres within 0.37% nickel over

120 metres in REI25-70

• 0.27% nickel over 620.0 metres, including 0.38% nickel over 21.0 metres within 178.0 metres

of 0.30% in REI24-59

The initial mineral resource for Reid was published in late 2024 by Canada Nickel (see news release dated

December 23, 2024). Since that time, drilling has continued with the goal of adding to the resource in the

Measured, Indicated and Inferred categories. Assays from the last three drillholes of the 2024 campaign

are presented here (see Table 1 and Figure 1).

Reid is a large serpentinized ultramafic consisting mainly of dunite and minor peridotite with multiple

intervals of higher-grade nickel mineralization. Near the centre of the intrusion is the “Central Dyke

Corridor” which has slightly lower grades of nickel that are interrupted by north-south oriented dykes.

Twenty-eight additional drillholes were completed in the spring of 2025 at Reid, with eight drillholes

presented in this release. These holes all intersected long mineralized intervals comprised mainly of dunite

and minor peridotite. REI24-59 and REI25-70 were both drilled in the western half of the geophysical

target where it intersected higher grade nickel mineralization, confirming the continuity on strike of one

higher grade horizon that is oriented west-northwest to east-southeast. Drilling through the Central Dyke

Corridor encountered thick intervals of mineralization including REI25-68 which intersected 0.28% nickel

over 471.6 metres. Twenty drillholes remain to be released with assays pending.

Mann Property

The Mann property is located 22 kilometres east of Crawford between Timmins and Cochrane, and is 80%

owned by Canada Nickel and 20% by Noble Mineral Exploration through a company called East Timmins

Nickel Ltd. The property hosts four separate targets: Mann North, Mann West, Mann Central and Mann

South.

Mann West

Highlights:

• 0.33% nickel over 52 metres within 480 metres of 0.27% nickel in hole MAN24-65

Mann West is approximately 3.5 kilometres long by up to 1.1 kilometres wide (covering 3.4 square

kilometres). Drilling focused on the southern half of the target and is now completed over a strike length

of 1.7 kilometres and a width of at least 600 metres. The most recent drilling intersected long sections of

well-serpentinized peridotite and minor dunite with disseminated and visible nickel sulphide

mineralization consisting primarily of pentlandite and heazlewoodite. The Company has drilled a total of

39 holes at Mann West , 31 of which were drilled during the 2024 campaign (Figure 2). The company is

currently working on an initial resource estimate expected in June 2025. Assays from the last three holes

are presented in this release (Table 2).

Deloro Property

Highlights:

• 0.38% nickel over 48 metres within 347 metres of 0.26% nickel in hole DEL24-35, with

mineralization starting at 6 metres below surface

• 0.26% nickel over 411.0 metres in hole DEL24-40, with mineralization starting only 2 metres

below surface

The Company produced the first resource for the Deloro property in the summer of 2024 (see July 18 ,

2024 news release). Deloro shows consistent mineralization within the dunite and peridotite units, with

thin overburden throughout the target, as seen in drillhole DEL24-40 with mineralization starting only 2

metres below surface. In the late fall of 2024 , Canada Nickel drilled an additional 21 holes to infill and

upgrade the existing resource. This release presents results for four drillholes (Table 3), with only one

drillhole remaining.

A resource update for Deloro is expected by end of year 2025.

the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

Quality Assurance and Control, Drilling and Assaying

Edwin Escarraga, MSc, P.Geo., a " Qualified Person" as defined by National Instrument 43 -101, is

responsible for the on-going drilling and sampling program, including quality assurance (QA) and quality

control (QC). The NQ sized core is collected from the drill in sealed core trays and transported to the core

logging facility. The core is marked and sampled at 1.5 metre lengths and cut with a diamond blade saw.

One set of samples is transported in secured bags directly from the Canada Nickel core shack to Actlabs

Timmins, while a second set of samples is securely shipped to SGS Lakefield for preparation, with analysis

performed at SGS Burnaby. All are ISO/IEC 17025 accredited labs. Analysis for precious metals (gold,

platinum and palladium) are completed by Fire Assay while analysis for nickel, cobalt, sulp hur and other
