Canada Nickel Reports Additional Exploration Drilling Results at Reid Nickel

Sulphide Property Including Over 1 kilometre of Nickel Mineralization

Highlights

• Longest interval to date at Reid - over 1 kilometre of nickel mineralization extending beyond

current resource at depth by 300 metres

o 0.28% nickel over 1,018 metres including multiple higher grade intervals (e.g., 0.36%

nickel over 97 metres and 0.42% nickel over 45 metres)

• Successfully infilled/extended existing nickel mineralization by 200 to 300 metres to the north,

west, and south

• Updated mineral resource expected by year-end 2025

TORONTO, September 4, 2025 – Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV:

CNC) (OTCQX: CNIKF) is pleased to announce additional exploration drilling results from its 100% owned

Reid Nickel Sulphide Project (“Reid”), located approximately 39 kilometres northwest of Timmins, Ontario.

CEO Mark Selby said, “Reid continues to deliver, with today’s results confirming its substantial potential

size and scale and the potential for multiple projects in the Timmins Nickel District. These results also

validate the considerable potential identified when the initial resource was published at the end of last

year, supported by a 3.9-square-kilometre geophysical target that is more than twice the size of Crawford.

We look forward to further demonstrating Reid’s scale with an updated resource by year-end.”

Reid Project

Reid is a large serpentinized ultramafic - with a geophysical footprint approximately 2.5 times larger than

that of Crawford’s - 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” where the main

dunite body is intersected by a series of north-south oriented dykes.

A drill program of 28 holes was completed in Q1-Q2 of 2025 with the purpose of infilling previous drill

sections and to produce an updated mineral resource by year-end 2025. The updated resource is expected

to significantly increase the size of the Inferred resource as well as upgrade the Indicated and Measured

categories. A previous news release (May 28, 2025) contained assay results of the first eight drillholes

from the infill program. This release contains assay results from the final 20 drillholes (see Table 1 and

Figures 1-4).

The Initial Reid Resource published on December 23, 2025, contained an Indicated Resource of 0.59 billion

tonnes grading 0.24% nickel containing 1.4 million tonnes of nickel, an Inferred Resource of 0.99 billion

2

tonnes grading 0.23% nickel containing 2.2 million tonnes of nickel. An Exploration Target1 potential was

defined for an additional 0.9-2.1 billion tonnes grading 0.20-0.22% nickel.

These last 20 holes all intersected long intervals of mineralized dunite and minor peridotite. REI25-82 and

REI25-89 were both drilled in the western half of the geophysical target to test for shallow, higher grade

nickel mineralization which was intersected immediately below overburden.

define a mineral resource; it is uncertain if further exploration will result in the target being delineated

as a mineral resource.

Statement Regarding TSX Venture

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in policies of

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

elements are performed using a peroxide fusion and ICP-OES analysis. Certified standards and blanks are

inserted at a rate of 3 QA/QC samples per 20 core samples making a batch of 60 samples that are

submitted for analysis.

Qualified Person and Data Verification

Stephen J. Balch P.Geo. (ON), VP Exploration of Canada Nickel and a " Qualified Person" as such term is

defined by National Instrument 43 -101, has verified the data disclosed in this news release, and has

otherwise reviewed and approved the technical information in this news release on behalf of Canada

Nickel Company Inc.
