Timmins-area mine tests groundbreaking CO₂ storage method

Canada Nickel (TSXV: CNC; US-OTCQB: CNIKF) has announced the successful completion of an in-situ carbon sequestration pilot study at its flagship Crawford nickel project near Timmins, Ontario. The company conducted the pilot in collaboration with a team funded by the U.S. Department of Energy's Advanced Research Projects Agency – Energy (DOE ARPA-E), led by Dr. Estibalitz Ukar from the University of Texas at Austin.

The company is pursuing trademark applications for terms such as NetZero NickelTM and NetZero CobaltTM, aiming to produce net zero carbon nickel, cobalt, and iron products.

"This achievement marks another critical milestone toward realizing a zero-carbon industrial cluster in the Timmins region. By successfully demonstrating a third pathway for utilizing our ultramafic deposits to capture and store carbon – in addition to the IPT carbonation and NetCarb processes – we are expanding the tools available for large-scale decarbonization," Mark Selby, CEO of Canada Nickel, stated.

The pilot project, which took place between mid-November and mid-December 2025, involved injecting approximately 12 tonnes of CO₂ into a single well drilled to a depth of 396 meters. The company reports that all injected CO₂ remained dissolved at depth, with no surface leakage detected.

"The Crawford in-situ mineralization field test shows that carbon capture doesn't have to be an add-on to mining--it can be built in from the very beginning. What we demonstrated at Crawford represents more than an experiment at a single site, it's a scalable model for how mining can contribute to global decarbonization," Dr. Ukar commented on the significance of the test, said.

The pilot project utilized an extensive monitoring network, including water monitoring wells, seismic monitoring stations, and satellite measurements. No significant seismic events or CO₂ leakage were observed during the test period.

Canada Nickel plans to continue monitoring seismicity, water chemistry, and potential CO₂ gas leakage in the coming months. The company views this initiative as a key step in expanding its carbon capture and storage capabilities, complementing its existing in-process tailings (IPT) carbonation and NetCarb programs.
