Canada Nickel’s Crawford mine could be low carbon nickel leader, Skarn says

Canada Nickel Company, following an assessment from metals and mining ESG research company, Skarn Associates, claims its Crawford project in Ontario, Canada, could have an industry leading low carbon footprint, lower than 99.7% of existing global nickel production.

When in operation, Crawford is expected to produce 2.05 t of carbon dioxide (CO2) per tonne of nickel-equivalent production over the life of mine, which is 93% lower than the industry average of 29 tonnes of CO2, it said.

These results are based on a study by Skarn Associates, applying data from Canada Nickel’s preliminary economic assessment (PEA), the results of which were released on May 25, 2021. This study from Ausenco estimated annual average nickel production of 34,000 t over a 25-year life of mine, use of autonomous trolley trucks and electric shovels to reduce diesel use by 40%, and optimisation of the carbon sequestration potential of the tailings and waste rock. A feasibility study on the project is expected to be completed by mid-2022.

On the Skarn study, Canada Nickel said: “Importantly, this CO2 footprint estimate does not include the carbon offset expected to be provided from the process of spontaneous mineral carbonation from the tailings and waste rock comprised largely of serpentine rock which naturally absorbs CO2 when exposed to air.”

Mark Selby, Chair & CEO of the company, said: “This study demonstrates that Canada Nickel’s Crawford project can be a world-leading large scale, low cost nickel supplier while possessing an extremely low carbon footprint. I am particularly excited that we can achieve this result even before we include the carbon offset potential from our waste rock and tailings which we expect to allow us to produce NetZero NickelTM, NetZero CobaltTM, and NetZero IronTM.

“These results reflect the mine’s low strip ratio and our ability to utilise the low carbon hydroelectricity in the region and by using trolley trucks and electric shovels to reduce the consumption of diesel fuel.”

Skarn Associates’ proprietary E0 GHG intensity metric relates to Scope 1 and 2 mine site emissions from mining and processing of ore, plus fugitive emissions. It includes emissions from integrated smelting and refining facilities, but excludes emissions from third-party smelting and refining, Canada Nickel explained.

Emission intensities are stated on a recovered nickel-equivalent basis, calculated using average 2020 metal prices. Emissions are pro-rated across all commodities produced by the mine, based on contribution to gross revenue.

Canada Nickel investigates Crawford processing potential at Glencore’s Kidd concentrator

Canada Nickel Co says it has entered into a non-binding Memorandum of Understanding (MoU) with Glencore Canada that could see material mined from Canada Nickel’s Crawford nickel-cobalt sulphide project treated and processed at Glencore’s Kidd concentrator and metallurgical site in Timmins, Ontario.

Crawford, around 40 km north of Glencore’s operations, hosts a 657 Mt measured and indicated resource grading 0.26% Ni and 0.013% Co. It is currently the subject of a preliminary economic assessment (PEA).

The Kidd operations consisting of the Kidd metallurgical site and the Kidd mine. The concentrator is located on the property of the Kidd Metallurgical Site, 27 km east of Timmins, in the Townships of Hoyle and Matheson. Built in 1966 with numerous upgrades over the years, the concentrator currently processes metal ore to produce copper and zinc concentrates. The facility has a design rated capacity of 12,500 t/d and is fully permitted with water taking and discharge permits and thickened tailings storage. The site has incoming and outgoing rail service via Ontario Northland Railway.

Canada Nickel says it has completed an initial high-level assessment of the potential arrangements envisaged under the MoU and will proceed with a detailed study on the potential for upgrading excess capacity at the Kidd concentrator and/or using the existing infrastructure in place at the Kidd metallurgical site for milling and further processing the nickel-cobalt and magnetite concentrates that are expected to be produced from Crawford.

Mark Selby, Chair and CEO of Canada Nickel, said: “The opportunity to utilise the excess capacity and existing infrastructure at the Kidd Met Site provides the potential to allow a faster, simpler, smaller scale start-up of Crawford at a vastly lower capital cost while the company continues to permit and develop the much larger-scale project currently being contemplated.

“Given the potential for this significant change in the scope of the project start-up, the release of the PEA will be delayed until the end of March 2021 to allow this option, if successful, to be incorporated.”

This study is being led by Ausenco Engineering Canada Inc, which is also supporting the assessment of the Kidd Met Site facilities.

Canada Nickel’s plans include the development of a “Zero-Carbon footprint operation”. This considers the use of electric rope shovels and trolley trucks which utilise electricity, rather than diesel fuel, as a power source wherever possible, along with a natural mineral carbonation approach for the deposition of waste rock and tailings during mining to allow material to absorb CO2.
