TORONTO, Ontario — February 19, 2026 — Leads & Copy — Canada Nickel Company Inc. has successfully completed an in-situ carbon sequestration pilot study at its Crawford Nickel Project near Timmins, Ontario.
The pilot, conducted with the U.S. Department of Energy’s Advanced Research Projects Agency – Energy (DOE ARPA-E) funded team led by Dr. Estibalitz Ukar from the University of Texas at Austin, demonstrated the sequestration of 12 tonnes of CO2 at the Crawford Nickel Project.
Mark Selby, CEO of Canada Nickel, said this achievement is a milestone toward realizing a Zero-Carbon Industrial Cluster in the Timmins region. He noted the direct injection approach could lower future mining costs by pre-conditioning and fracturing the rock mass, reducing the energy needed for blasting and processing.
Dr. Ukar stated that the Crawford field test shows carbon capture can be integrated into mining from the start, creating environmental and economic value by permanently storing CO₂ while reducing mining energy requirements.
The CO₂ injection field test, which followed nearly two years of planning and laboratory experiments, took place between mid-November and mid-December 2025. Data indicates the test proceeded as planned, with approximately 12 tonnes of injected CO₂ remaining dissolved at depth and no surface leakage detected.
Starting November 20, 2025, short-duration injection trials were conducted over 12 days, until December 1st. From December 2nd to December 18th, CO2-saturated water was continuously injected into a single well drilled to 396m, with an injection interval between 350m and 396m. The trials confirmed the injected CO₂ remained fully dissolved within the water column, with no upward migration of CO₂ gas.
Water for dissolving carbon dioxide was sourced from an onsite well. The test configuration included an injection well, a water supply well, four water monitoring wells, 12 surface seismic monitoring stations, and three seismic monitoring boreholes.
Seismicity and potential CO₂ gas leakage were continuously monitored. No significant seismic events (M>1) were detected, and no CO₂ was observed emerging from monitoring wells or through the silty sedimentary cover. Preliminary chemical analyses suggest the injected CO₂-rich water had not reached the monitoring wells. No surface leakage was detected.
Monitoring of seismicity, water chemistry, and potential CO₂ gas leakage will continue in the coming months. Monitoring wells will be re-entered and sampled in the spring. The area is also being monitored using InSAR satellite measurements.
This initiative is independent of Canada Nickel’s In-Process Tailings (IPT) Carbonation and NetCarb Programs and represents a key step in expanding the Company’s carbon capture and storage capabilities. Results from this study will help guide future post-mining carbon sequestration strategies.
Canada Nickel Company Inc. is focused on developing nickel-sulphide projects to supply the electric vehicle and stainless-steel markets. The company has applied to trademark the terms NetZero NickelTM, NetZero CobaltTM, NetZero IronTM and is developing processes to produce net zero carbon nickel, cobalt, and iron products. Its flagship Crawford Nickel-Cobalt Sulphide Project is located in the Timmins-Nickel District.
