Canada Nickel and the University of Texas at Austin Launch Carbon

Sequestration Pilot at Crawford Nickel Project

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 Carbonation and NetCarb initiatives

• Supports the development of a Zero-Carbon Industrial Cluster in Northeastern Ontario

TORONTO, November 3, 2025 - Canada Nickel Company Inc. ("Canada Nickel" or the " Company") (TSX-V:CNC)

(OTCQB: CNIKF) is pleased to announce an in-situ carbon sequestration pilot study at its flagship Crawford Nickel

Project (“Crawford”), near Timmins, Ontario. The pilot is being conducted in collaboration with the U.S. DOE ARPA-

E team, led by the University of Texas at Austin.

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, CEO 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 and create the potential, by pre -carbonating 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 ac tion. By advancing novel methods for permanent CO 2 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 CO 2

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 post-mining carbon sequestration strategies, further strengthening Canada Nickel’s vision for a Zero-

Carbon Industrial Cluster in Timmins.
