Canada Nickel Announces Significant Awaruite at Midlothian Property

Highlights

• 79% of the total nickel at Midlothian is contained in awaruite, a high-grade nickel-iron alloy
• Mineralogical and Davis Tube Recoverable ("DTR") analysis confirm significant awaruite, with DTR grades of 0.15%, 0.14%, and 0.12% nickel on composite samples – comparable to other awaruite deposits
• Brucite content averages 5.6%, more than 2.5 times higher than Crawford, indicating strong carbon storage potential

TORONTO, Feb. 26, 2026 /CNW/ - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQX: CNIKF) is pleased to announce mineralogical and metallurgical results from its 100% owned Midlothian Project ("Midlothian"), which confirm significant recoverable awaruite with grades and scale comparable to other leading awaruite deposits. An initial resource for Midlothian was published on December 18, 2025 with 590 million tonnes Inferred at 0.28% nickel. Midlothian, located in the Timmins Nickel District, is also well-positioned to leverage existing regional infrastructure. 

CEO Mark Selby said, "Today's announcement is another exciting development in the Timmins Nickel District confirming Midlothian as a significant deposit. The strong results across all samples highlight the potential of this resource, which contains significant quantities of awaruite ranging from 0.25-0.36% and has the highest average nickel grade in our portfolio (0.28%) and total nickel grades more than 30% higher than other leading awaruite deposits. Midlothian is emerging as one of the most promising deposits in the District."

Mr. Selby continued, "We are encouraged by these early results, especially as initial DTR tests were done at coarser grind size than other deposits. A finer grind may yield even higher DTR nickel results. Because the awaruite mineralization has been confirmed to be widespread at Midlothian, the Company plans to assay all existing and future drill holes to allow a DTR nickel resource grade to be calculated in addition to a total recoverable nickel resource."

Midlothian Project

Midlothian is located 64 kilometres southwest of Timmins and 20 kilometres west of Matachewan, Ontario. It is a large serpentinized ultramafic approximately 2.5 km long and up to 520 metres wide - with a geophysical footprint of 1.7 km² (similar to the combined footprint of Crawford's Main and East Zones) - consisting mainly of a highly serpentinized dunite core with minor peridotite and significant awaruite nickel mineralization accounting for up to 79% of the total nickel content.

An initial total nickel resource estimate was published at the end of 2025 (see news release December 18, 2025) containing an Inferred Resource of 0.59 billion tonnes grading 0.28% nickel for a total of 1.68 million tonnes of nickel. The resource estimate was based on 22 drillholes, where all drillholes were sampled for geochemical analysis at an average rate of one core sample per 1.5 metres. In addition, one sample every twenty core samples was selected and submitted for mineralogical (QEMSCAN) testing.

This release summarizes the mineralogical results for 177 samples from the first 14 of the 22 drillholes (Figure 1), as well as metallurgical results for four separate composite representing different mineralization styles within the deposit (Table 1). The results highlight the thoroughly serpentinized nature of the ultramafics and confirm the different mineral forms in which nickel is hosted. Mineralogical results on the remaining eight holes are pending. The nickel mineralization is dominated by a nickel-iron alloy (awaruite) and minor nickel sulphide (heazlewoodite) Figure 2, Table 1. Both awaruite and heazlewoodite are minerals that have a higher nickel tenor, ranging between 65-75% nickel content.

Brucite, a key mineral indicator for carbon sequestration potential was also identified by QEMSCAN. Midlothian contains significantly higher abundance than both Crawford's East and Main Zones. (Figure 3)

Comp-A comprised 62 samples totaling 93 metres in core length; COMP-B comprised 50 samples totaling 77 metres; COMP-C comprised 30 samples totaling 45 metres; COMP-D comprised 58 samples totaling 87 metres.

Average nickel grade is 0.28% (see release December 18 2025)

*Mineral Averages are from 177 QEMSCAN samples across the Midlothian deposit

Davis Tube Recovery Tests

Metallurgical testing was conducted at the XPS laboratory in Sudbury, Ontario on four samples representing different mineralization styles taken from the Midlothian drill core. The samples were prepared to target variability in mineral grain sizes and serpentine speciation. The samples were subjected to Davis Tube testwork by grinding the samples and passing them through a magnet with wash water. The recovered magnetic fraction was then characterized as the "Davis Tube Recoverable" or "DTR" fraction. The test results summarized in Table 2 show DTR grades ranging from 0.07-0.15% nickel and 2.6-3.6% iron. There is potential to increase the DTR grades through finer grinding as the primary grind size of ~190 µm was coarser than what has been reported by others (e.g., 75 µm).

Table 2. Davis Tube Test Results Summary

Table 3 summarizes the results of microprobe investigations for each of the four samples that were subjected to Davis Tube testing. The results demonstrate the high nickel tenor of heazlewoodite and awaruite minerals and the low nickel grade of serpentine. These results coupled with the Davis Tube nickel results are encouraging because they show that nickel has been liberated from the olivine minerals through the serpentinization process.
