Canada Nickel Reports Additional Positive Exploration Drilling Results at Midlothian Nickel Sulphide Property

Highlights

• MID25-17A intersected strong nickel mineralization immediately below overburden at 5.3 m with 0.30% nickel over 18.7 m and 0.30% nickel over 330.0 metres
• MID25-18A intersected 0.29% nickel over 449.0 metres including 0.36% nickel over 10.5 metres
• Successfully extended outline of nickel mineralization by 200-300 metres to the south
• Initial mineral resource expected by year-end 2025

TORONTO, Sept. 25, 2025 /PRNewswire/ - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQX: CNIKF) is pleased to announce further positive exploration drilling results from its Midlothian Property located 70 kilometres south-southeast of Timmins and 25 kilometres west of Matachewan. These latest results underscore the property's growing potential and Midlothian's position as a significant asset within Canada Nickel's portfolio.

CEO Mark Selby said, "The third of our "Three Giants" continues to exceed expectations.  The latest drill assays from Midlothian have delivered the most consistently higher-grade intervals we've seen across any of our 18 drilled properties, with the most recent three holes each returning 0.29–0.30% nickel over several hundred meters of core.  With a target footprint larger than our Crawford project and shallower overburden, Midlothian is showing its potential through these results. We look forward to announcing its initial resource estimate later this year."

Midlothian Property

The Midlothian property is directly accessible by road all year round. Midlothian is a joint-venture between Canada Nickel and Canadian Gold Miner Corp. and Laurion Mineral Exploration Inc. and is in the final year of a four year agreement where Canada Nickel needs to make a final payment of $400,000 and issue 140,000 shares to earn a 100% interest in the property.  Six infill drillholes were completed during the summer of 2025. All six holes intersected long largely continuous intervals of mineralized dunite with the two holes collared on top of the mineralization intersecting it at shallow depths less than seven metres (Figure 1). These holes were drilled on a geophysical target measuring 2.7 kilometres long and 0.4 to 0.9 kilometres wide with a target footprint of 1.7 km² (compared to Crawford target footprint  of 1.5 km²). This release contains assay information on three completed holes. Assays are still pending on the three remaining drillholes. With the combined dataset (2023,2024, 2025 drilling), the Company intends to produce an initial resource estimate at Midlothian by year end 2025.

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 – Standards of Disclosure for Mineral Projects, 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. Samples are transported in secured bags directly from the Canada Nickel core shack to Actlabs Timmins. Actlabs is a ISO/IEC 17025 accredited lab. Analysis for precious metals (gold, platinum and palladium) are completed by Fire Assay while analysis for nickel, cobalt, sulphur 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 – Standards of Disclosure for Mineral Projects, 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.
