(All amounts in US dollars unless otherwise indicated.)

TORONTO, May 25, 2021 - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQB: CNIKF), is pleased to announce that the Preliminary Economic Assessment ("PEA") has confirmed robust economics showing an after-tax NPV_8% of $1.2 billion and an after-tax IRR of 16% from its wholly owned flagship Crawford Nickel Sulphide Project ("Crawford") located in Timmins, Ontario, Canada. The PEA, prepared by Ausenco Engineering Canada Inc. ("Ausenco") in accordance with National Instrument 43-101 ("NI 43-101"), demonstrates the potential to develop a phased conventional nickel sulphide concentrator, producing nickel concentrates and magnetite concentrate. The operation is designed to have an open pit mine with a plant potential of 120,000 tonnes per day.

The Company is immediately advancing the project to a feasibility study, which is expected to be completed by mid-2022.

"We are focused on delivering the next generation of nickel and are pleased that this PEA demonstrates the robust economics of our flagship Crawford project. The PEA, utilizing just a fraction of our resource potential, demonstrates that we expect to be one of the largest nickel sulphide operations globally, producing 1.9 billion pounds of nickel over a 25-year period with net cash costs of just over $1 per pound. Our current focus on the stainless steel market allows us to fully utilize the substantial by-product value for the contained iron and chrome, placing us on the lower end of the cost curve. I am very proud of our team for delivering these results in just over 20 months since our first drill holes and I look forward to continuing to unlock the district scale nickel potential of the Timmins region," said Mark Selby, Chairman and CEO of Canada Nickel.

Mr. Selby further stated, "The PEA is a milestone that enables a whole range of key activities as we aggressively advance the project towards production by the middle part of the decade. We are immediately embarking on a feasibility study. We are calculating our carbon footprint and evaluating Crawford's potential to deliver NetZero Nickel^TM, NetZero Cobalt^TM and NetZero Iron^TM. We are exploring opportunities to deliver the nickel in our concentrates into the electric vehicle ("EV") market. We have begun our Environmental and Social Impact Assessment ("ESIA"), and we continue to work in partnership with Indigenous and local communities. We intend to implement an extensive and inclusive stakeholders' consultation process that will allow us to identify and mitigate the project impacts in order to deliver sustainable benefits for multiple generations."

Crawford PEA Summary

Note on assumptions

• The Company utilized metal price assumptions from third party sources applying a nickel price of $7.75/lb, a chromium price of $1.04/lb and an iron price of $290 per tonne (based on U.S. benchmark iron scrap price). In addition, a US$/C$ exchange rate of $0.75 and oil price of US$60/barrel were also applied.
• Further details on production can be found on the Company's website at www.canadanickel.com
• Revenue & Costs information and Cash Flow data are non-IFRS measures. Refer to Non-IFRS measures.

Additional Opportunities
There remains significant potential for additional value to be created at the Crawford project through a number of identified opportunities, which include:

• Significant additional exploration potential within the Crawford project and at the Company's additional properties including the Company's most recent acquisition at Bradburn/Dargavel
• Optimization of nickel, iron, chrome recovery and concentrate grades through additional testwork during feasibility study stage
• Determination of the carbon capture potential from the carbon sequestration potential of the Company's tailings and waste rock to permit the Company to achieve net zero carbon footprint operation production of NetZero Nickel^TM, NetZero Cobalt^TM and NetZero Iron^TM products
• Processing of nickel concentrates to capture cobalt, platinum group metals ("PGM") content through various processing alternatives for the company's high grade and standard grade concentrates and deliver nickel and cobalt to EV market
• Capital cost reductions via electricity distribution and fleet acquisition opportunities through the Company's Memorandum of Understanding with Taykwa Tagamou First Nation to participate in the financing of all or a portion of the project's electricity supply and heavy mining equipment fleet required for Crawford's operation
• Completion of negotiations to potentially utilize Glencore's Kidd Creek mill based on the capital and operating costs successfully determined during the initial phase of work.

Crawford Overview
The Crawford project will be a conventional open pit mine/mill operation powered by zero-carbon electricity and utilizing trolley trucks and electric rope shovels to minimize its carbon footprint through reduced diesel consumption. The project will produce three products: (1) a high-grade concentrate estimated at 35% nickel; (2) a standard grade concentrate estimated at 12% nickel; and (3) a magnetite concentrate estimated at 48% iron and 3% chromium. All of the products are assumed to be sold based on the nickel, iron, and chromium content of the concentrates on terms which provide sufficient incentive for the construction of a co-located stainless steel mill using the same RKEF-AOD approach utilized very successfully in China and Indonesia. The Company's wholly-owned subsidiary NetZero Metals Inc. will begin negotiations with potential partners immediately following the release of the PEA.

The process plant will utilize a conventional milling operation consisting of crushing, grinding, desliming and flotation operations consistent with other ultramafic nickel operations. The process plant will be constructed in three phases. Phase I will have a steady-state throughput of 42,500 tonnes per day using a single 36 x 24 foot semi-autonomous grinding mill and a 26.5 x 44 foot ball mill grinding circuit. Phase II will double throughput starting in year four, by mirroring the first line. Phase III will raise production to the ultimate rate of 120,000 tonnes per day through the addition of secondary crushing and a third ball mill and additional downstream capacity.

Location & Infrastructure
The Crawford project lies within the Abitibi upland physiographic region and has a typical "Laurentian Shield" landscape. The Crawford project is located in Crawford and Lucas townships, about 42 kilometres north of the city of Timmins in the heart of the prolific Timmins-Cochrane mining camp in Ontario, Canada, and is adjacent to well-established, major infrastructure associated with over 100 years of regional mining activity. The Crawford project is located adjacent to a paved highway, a power line with sufficient capacity for the construction period, with other major power lines and rail access located nearby.

Mining
The Crawford project is currently comprised of two separate open pits. The mine production plan includes 37% of the overall mill feed from inferred resources. Mining will commence in the Main Zone, which represents approximately 77% of the total mineralized material. Over 90% of the material mined will be rock, which will be drilled and blasted before being loaded by 700 tonne class electrically powered hydraulic excavators into 290 tonne autonomous trucks that will use trolley assist on uphill hauls. The remaining material will be overburden, which will not require drilling and blasting and will be loaded and hauled with a mixed fleet including 45 tonne, 90 tonne and 290 tonne trucks. Mining of the East Zone will commence after the Main Zone is depleted in year 17 and will continue through year 25. A key element of the mine plan is the de-coupling of mine production rates for the Main Zone from that of the plant. This allows for accelerated output of metal in the early years from higher grade and recovery material, while lower grade and recovery material is stockpiled and used to supplement feed from the East Zone in later years. This strategy also allows tailings produced from the second half of year 17 onwards to be impounded within the mined-out Main Zone, significantly reducing the size and associated cost of the Tailings Storage Facility.

Inclusion of the trolley assist option is a major driver in reducing greenhouse gas (GHG) emission, noise level, fleet size and overall project environmental footprint.

Mineral Processing
The concentrator and associated infrastructure facilities will process run-of-mine or stockpiled material using a conventional milling process. Unit steps in the flowsheet include: crushing, semi-autogenous and ball mill grinding, desliming, nickel flotation as well as magnetic separation of the flotation tails. The concentrator will produce three product streams: high grade nickel concentrate (35% nickel), standard nickel concentrate (12% nickel) and a magnetite concentrate that contains approximately 48% iron and 3% chromium. Nickel, iron and chromium are three key alloying metals in the production of stainless steel, which makes Canada Nickel products suitable feeds for this market and increases the value of the product per tonne of nickel due to the stainless steel pricing and premiums available in the United States and European markets.

Based on analysis by CRU, utilization of scoping study work completed by Kingston Process Metallurgy Inc. (KPM) and Steel and Metals Market Research (SMR), the Company should be able to achieve 91% payability for contained nickel, 71% payability for contained iron, and 43% payability for contained chromium in its feeds and provide sufficient incentive for the construction of a local stainless steel mill which would also produce additional nickel pig iron products based on the nickel/iron mix of the feeds.

At this time, the Company is not receiving any value for the contained cobalt and PGM content in its nickel concentrates as the Company has chosen a stainless steel path which currently provides the most value to the Company and can reliably be processed into conventional products utilizing existing, proven technology. With rapidly increasing demand from the EV market, we will consider these processing options if they provide additional value for the Company's project output. Discussions with various supply chain participants in the EV supply chain are expected to accelerate now with the completion of the PEA.

Capital Cost Estimate

The total capital estimate includes the direct field cost for executing the project, the contractor's costs for construction management, the indirect costs of construction, the owner's indirect costs associated with design, construction and commissioning, as well as the cost of the owner-provided mining fleet and internal costs for preproduction development, including stockpiled inventory. The capital does not include escalation, interest, or working capital. Working capital has been included in the economic analysis.

The PEA is preliminary in nature and as such an average contingency of 25% was applied to both initial and expansion capital expenditures.

Operating Cost Estimate

Operating costs were developed using a zero based model calibrated against the actual results of peer operations. Labour costs include the benefits of the use of productivity improving technologies such as autonomous trucks and drills while diesel costs will be minimized through the use of trolley-assisted haulage.

Sensitivities

Sensitivity analysis does not reflect changes in underlying cost with changes in metal prices.

Next Steps
With the successful completion of the Crawford PEA, Canada Nickel is immediately initiating a feasibility study with a timeline for a mid-year 2022 release. The Company has started work on its ESIA which is a key step in its permitting process which the company will aggressively advance alongside the work on the feasibility study. The Company will also continue to explore its additional nickel properties in addition to Crawford.

The technical report in support of the PEA will be filed under Canada Nickel's profile on SEDAR at www.sedar.com within 45 days of the date of this press release.

Non-IFRS Measures
The Company has included certain non-IFRS measures in this press release. The Company believes that these measures provide investors an improved ability to evaluate the underlying performance of the project. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers.

Net C1 cash costs are the sum of operating costs (including all expenses related to stripping), net of by-product credits from chromium and iron ore per pound of payable nickel. Net AISC (all in sustaining costs) are C1 cash costs plus royalties plus sustaining capital per pound of payable nickel. Sustaining and expansion capital are non-IFRS measures. Sustaining capital is defined as capital required to maintain operations at existing levels. Expansion capital is defined as capital expenditures for major growth projects or enhancement capital for significant infrastructure improvements at existing operations. Both measurements are used by management to assess the effectiveness of investment programs.

NSR (Net Smelter Return) includes gross revenues less refining costs. EBITDA is earnings before interest, taxes and depreciation, which comprise NSR less royalties and operating costs and for the purpose of the economic analysis assume all stripping costs are expensed. Free cash flow represents operating cash flow less capital expenditures.
