Canada Nickel Announces Discovery at MacDiarmid Nickel Project

Highlights:

• First three drill holes returned significant intersections of mineralized dunite

TORONTO, May 18, 2021 - Canada Nickel Company Inc. ("Canada Nickel" or the "Company") (TSXV: CNC) (OTCQB: CNIKF) today announced preliminary results from the start of its drill program at the MacDiarmid Nickel Project located 23 kilometres southwest of the Company's initial Crawford discovery. Assays are pending on all holes.

Mark Selby, Chair & CEO said, "We are very pleased to have made a second discovery, following our initial success in Crawford Township. The first three holes drilled at MacDiarmid returned significant intersections of mineralized dunite similar to the average mineralization we initially discovered at Crawford. The results of our Preliminary Economic Assessment for Crawford will now be released on May 25^th with a conference call to be held the following morning at 10 am EDT May 26^th."

Steve Balch, VP Exploration said, "These results confirm the success of our geophysical targeting approach by successfully drilling our first new target identified on our option properties. We look forward to drilling the other targets identified across our four additional nickel properties, and our recently added sixth target at Bradburn/Dargavel."

The MacDiarmid Project is located 15 kilometres west of the world-class Kidd Creek Mine and 23 kilometres southwest of the Company's initial discoveries in Crawford Township. The Crawford Nickel-Cobalt Sulphide Project is located 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.

MacDiarmid Nickel Project

The MacDiarmid ultramafic intrusion ("MUI") is approximately 3 kilometres long and 150 to 600 metres wide with the primary target a set of coincident geophysical anomalies of 1.8 kilometres long and up to 400 metres wide. Three holes were collared on the eastern side of the intrusion spaced 200 metres apart and were designed to intersect dunite-peridotite at right angles to the strike direction of the MUI. Mineralization has been defined across a strike length of 400 metres to a maximum depth of 360 metres and widths of 150-200 metres. All holes were drilled to the south (205^o azimuth) at -50^o inclination.

MacDiarmid Nickel Project Drill Hole Orientation

MAC21-01 was drilled to a depth of 411 metres and intersected primarily dunite-peridotite beginning at 26 metres including an interval of primarily dunite (156 metres true thickness) beginning at 99 metres.

MAC21-02 was collared 200 metres west of MAC21-01 into peridotite at 36 metres and drilled to a depth of 424 metres, intersecting primarily dunite-peridotite (187 metres true thickness).

MAC21-03 was collared 200 metres east of MAC21-01 close to the eastern margin of the intrusion and intersected dunite to a depth of 336 metres (199 metres true thickness) beginning at 29 metres.

All holes encountered minor (3 - 15 metres thick) felsic to intermediate dikes.
