Canada Nickel Identifies New Method for Accelerated CO2 Capture


br />

Simple carbon capture approach could allow production of Net Zero nickel and generation of

21 tonnes of CO2 credits per tonne of nickel produced after offsetting all emissions

Demonstrates potential to turn a nickel mine into a generator of carbon credits rather than generator of carbon emissions

Crawford Project could produce an estimated average of 710,000 tonnes of CO2 credits annually and 18 million total tonnes of CO2 credits over expected life of mine

TORONTO, July 20, 2022 – Canada Nickel Company Inc. (\”Canada Nickel\” or the \”Company\”) (TSXV:CNC) (OTCQX:CNIKF – https://www.commodity-tv.com/ondemand/companies/profil/canada-nickel-company-inc/ ) today announced the results of a laboratory test program for a new method of accelerated carbon capture – In Process Tailings Carbonation (“IPT Carbonation”) that the Company believes has transformative potential.

The lab scale test program demonstrates that this accelerated carbon capture process could allow Crawford tailings to absorb enough CO2 to achieve Net Zero carbon emissions within 36 hours, and generate up to 21 tonnes of CO2 credits per tonne of nickel produced within just six days, rather than the multiple months involved in existing passive tailings approaches.  At Canada Nickelâ€?s Crawford Project, this translates into an average of approximately 710,000 tonnes of CO2 credits per year and 18 million total tonnes of CO2 credits over the Preliminary Economic Assessment (“PEA”) life-of-mine.

Mark Selby, Chair and CEO of Canada Nickel commented, “These lab scale test results demonstrate a potentially transformative process to turn a nickel mine into a net generator of carbon credits rather than a generator of carbon emissions.  Our active and accelerated process has the potential to operate at least 8-12 times faster than current passive approaches, delivering carbon capture at a multiple of what industry leaders are currently able to achieve.  Our process also allows easier quantification and verification of the amount of carbon captured.”

Canada Nickelâ€?s Crawford Project is hosted in ultramafic rock, which naturally absorbs and sequesters CO2. The potential to actively capture and sequester carbon was a key consideration in Canada Nickelâ€?s acquisition of the 42 km2 of target ultramafic rocks in the Timmins area which could anchor a zero-carbon industrial cluster near Timmins. The challenge has been to develop a process that speeds up the naturally occurring carbon absorption process. Canada Nickel has developed a simple active process that utilizes tailings as generated in the milling process and injects a concentrated source of CO2 for a brief period of time.  This novel process for accelerated mineral carbonation is called In Process Tailings Carbonation or IPT Carbonation, which fixes CO2 geologically while the tailings are still in the processing circuit, rather than after they have been finally deposited.

While Canada Nickelâ€?s IPT Carbonation process has only been demonstrated on a lab scale and on a limited number of samples, the Company believes that, given its relative simplicity, this process could be scaled up with availability of concentrated (rather than atmospheric) sources of CO2. This CO2 could potentially be delivered by downstream processing of Crawford concentrates, a wide range of industrial processing activities, green hydrogen production, carbon capture facilities, or natural gas power generation.  The process clearly demonstrates the potential to produce NetZero NickelTM and NetZero CobaltTM for the EV industry, NetZero IronTM and chromium for the stainless steel industry and generate substantial carbon credits during the process. The Company believes that the need for a concentrated source of CO2 for this process and the substantial CO2 capture capacity potential of its ultramafic land position could form the basis for an entire zero carbon industrial cluster in the Timmins region.

IPT Carbonation

The IPT Carbonation process utilizes tailings directly from the mineral processing circuit and conditions them with CO2 for a brief period of time.  After this conditioning, the tailings achieved the Net Zero carbon capture target in less than 36 hours and achieved gross carbon capture rates of at least 26 tonnes of CO2 / tonne of nickel (5 times the amount necessary to achieve Net Zero metal production) in just 6 days.  During this time, the rate of capture was 8 to 12 times faster than a lab scale passive approach. (see Figures 1a, 1b, 2, 3).  Both samples tested with IPT Carbonation have achieved or surpassed the complete theoretical carbonation of the ultramafic mineral brucite, which is significant as the capacity of brucite to sequester carbon, at Crawford alone, is estimated to be more than 13 million tonnes of CO2 over the estimated life of the project. The experimental method and results for IPT Carbonation were initially completed at XPS, Expert Process Solutions, a Glencore Company, and the mechanism was then reproduced at a second independent lab, Kingston Process Metallurgy, adding confidence to the process. No further information is being provided on the method at this time and work is underway to test a wide range of variables to optimize the process.

Validation and Measurement of CO2 Credits

IPT Carbonation, which is an active process, has benefits over passive mineral carbon capture as the method for quantifying and verifying CO2 capture is expected to be much simpler. Using a standard carbon balance in the mineral processing facility, the CO2 captured from IPT Carbonation can be quantified before tailings are discharged into the permanent tailings storage facility such that carbon offsets can be quantified in real time as part of a standard metallurgical accounting system. Canada Nickel expects industry standards to be developed for quantifying CO2 capture through passive methods as well.
