CANADA NICKEL AND THE UNIVERSITY OF TEXAS AT AUSTIN LAUNCH CARBON SEQUESTRATION PILOT AT CRAWFORD NICKEL PROJECT

Canada Nickel Company Inc. has begun an in situ carbon sequestration pilot study at its flagship Crawford nickel project near Timmins, Ont. The pilot is being conducted in collaboration with the U.S. DOE (Department of Energy) ARPA-E (Advanced Research Projects Agency -- Energy) team, led by the University of Texas at Austin.

Highlights:

• Canada Nickel and the University of Texas at Austin launch a one-month in situ carbon injection pilot at the Crawford nickel project;
• Supported by funding from the U.S. Department of Energy's ARPA-E program;
• Pilot is independent of Canada Nickel's existing IPT (in-process tailings) carbonation and NetCarb initiatives;
• Supports the development of a zero-carbon industrial cluster in Northeastern Ontario.

The pilot program follows bench-scale studies conducted by the ARPA team under the direction of Dr. Estibalitz Ukar, research associate professor at the University of Texas at Austin.

Mark Selby, chief executive officer of Canada Nickel, said: "We have been very pleased to work with Dr. Ukar and her team at the University of Texas at Austin as they developed a novel carbon sequestration approach to store large volumes of CO2 [carbon dioxide] and create the potential, by precarbonating material before it is mined to both reduce the costs and to improve the value from processing the material. We look forward to the results from this next stage of testing in a real-world field trial."

Dr. Ukar said: "Canada Nickel has been an exceptional partner in this work, providing site access, geological data and active collaboration. Their support of this pilot exemplifies their commitment to responsible mineral development, scientific innovation and climate action. By advancing novel methods for permanent CO2 storage and supporting technologies that can scale globally, Canada Nickel is helping chart a sustainable path forward for the mining sector."

Bench-scale studies of the Crawford ultramafic rocks have demonstrated that the magnesium-rich mineral brucite captures CO2 by transforming into secondary minerals such as magnesite and nesquehonite. Building on these findings, the month-long pilot will inject carbon-enriched water sourced from the Crawford site into a 400-metre-deep well within the ultramafic body to evaluate large-scale carbon capture under natural conditions.

The CO2-to-rock mineralizing process is anticipated to begin within hours of the injection, with most of the CO2 turning into solid rock within six months. The pilot will use various monitoring techniques, including groundwater sampling, seismic sensors, gas detectors and satellite-based surface tracking.

This initiative is independent of Canada Nickel's in-process tailings (IPT) carbonation program and represents a key step in expanding the company's carbon capture and storage capabilities. Results from this study will help guide future postmining carbon sequestration strategies, further strengthening Canada Nickel's vision for a zero-carbon industrial cluster in Timmins.
