1.25 M Indicated Tonnes at 1.0% Ni and 2.01 M Inferred Tonnes at 1.0% Ni Isometric Image of Alexo-Dundonald Project Figure 1 Alexo-Dundonald Project Map Figure 2TORONTO, Dec. 01, 2020 (GLOBE NEWSWIRE) -- Class 1 Nickel and Technologies Ltd. (CSE:NICO) ("Class 1" or the "Company") is pleased to report an addition to its updated National Instrument 43-101 Mineral Resource Estimate (see press release issued by the Company on November 2, 2020) on its 100% owned Alexo-Dundonald Nickel Project (the “Project” or the “Property”) located about 45 km northeast of Timmins, Ontario. The Project comprises four foundation Mineral Resources: Alexo North; Alexo South; Dundonald North; and Dundonald South, which are situated within a regionally folded package of mafic to ultramafic (basalt and komatiite flows) rocks that trend through the strategic land package (Figure 2). A large portion of the Property remains untested by drilling.A photo accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/40a5e5fc-d850-4719-a074-d518a4ebd598Class 1 President Mr. Benjamin H Cooper stated, “as our expert technical team continues to source, collate and interpret comprehensive data relating to the four known Mineral Resources at Alexo-Dundonald, our knowledge and understanding of the 14 km mineralized system also continues to grow.”Modern validation of the Mineral Resource as well as intensive modelling of available data have now evaluated a series of previously known deeper diamond holes that have intersected considerable nickel sulphide mineralization tonnage to a depth from surface of approximately 650 m.A photo accompanying this announcement is available at https://www.globenewswire.com/NewsRoom/AttachmentNg/cc943ba2-f75c-4866-9456-12d0cfc3b973P&E’s Senior Associate Geologist, William Stone, Ph.D., P.Geo said, “these deeper intersections reveal potential to expand the Deposit by drilling down-dip/down-plunge of the apparent mineralization trend”.Class 1 President Mr. Benjamin H Cooper stated “1.25 million tonnes (Mt) of Indicated and 2.01 Mt of Inferred Mineral Resource is a nice solid starting point for the Company. As we continue to invest more capital wisely and systematically into expanding these open Mineral Resources, our experienced nickel team expects the Mineral Resource Estimate to increase substantially.”Following modelling of additional deep areas of the Dundonald North Deposit, Class 1 is now reporting a newly updated total estimated Inferred Mineral Resource of 2.01 Mt with an average grade of 1.01% Nickel (Table 1). The Indicated Mineral Resource of 1.25 Mt with an average grade of 0.99% Ni remains unchanged from the November 2, 2020 press release. Details of the current pit-constrained and out-of-pit Mineral Resources are provided in Table 2.Table 1: Alexo-Dundonald Updated Mineral Resource Estimate SummaryUPDATED ALEXO-DUNDONALD MINERAL RESOURCE ESTIMATE (1-9) ClassificationTonnes (M)Ni %Cu %Co %Contained Ni MlbContained Cu MlbContained Co Mlb Pit Constrained & Out-of-Pit Indicated1.250.990.040.0227.351.000.66 Out-of-Pit Inferred2.011.010.030.0244.511.290.89 NI 43-101 disclosure: (1) Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. (2) The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. (3) The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. (4) The Mineral Resources in this report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council. (5) The historical open pit mined areas were removed from the MRE. (6) US$ metal prices of $7.35/lb NI, $3/lb Cu, $20/lb Co, $1,500/oz Au, $900/oz Pt and $1,650/oz Pd were used in the NSR calculation with respective process recoveries of 89%, 90%, 40%, 50%, 50% and 50% (7) Pit constrained Mineral Resource NSR cut-off considers ore crushing, transport, processing and general and administration (G&A) costs that respectively combine for a total of ($2 + $6 + $20 + $2) = CAD$30/tonne processed. (8) Out-of-pit Mineral Resource NSR cut-off considers ore mining, crushing, transport, processing and G&A costs that respectively combine for a total of ($58 + $2 + $6 + $20 + $4) = CAD$90/tonne processed. (9) The out-of-pit Mineral Resource grade blocks were quantified above the $90/t cut-off, below the constraining pit shell and within the constraining mineralized wireframes. Additionally, only groups of blocks that exhibited continuity and reasonable potential stope geometry were included. All orphaned blocks and narrow strings of blocks were excluded. The longhole stoping with backfill mining method was assumed for the out-of-pit Mineral Resource Estimate calculation.Table 2 – Pit Constrained and Out-of-Pit Estimated Mineral Resources UPDATED ALEXO-DUNDONALD MINERAL RESOURCE ESTIMATE(1-9) ScenarioClassificationCut- off NSR C$/tTonnes (k)Ni (%)Ni (Mlb)Cu (%)Cu (Mlb)Co (%)Co (Mlb) Pit ConstrainedIndicated30593.40.7810.220.040.530.030.34 Out-of-pit Indicated90661.01.1817.130.030.470.020.32 Inferred902,007.51.0144.510.031.290.020.89 Total Indicated30+901,254.40.9927.350.041.000.020.66 Inferred902,007.51.0144.510.031.290.020.89 The NI 43-101 compliant Updated Mineral Resource Estimate was prepared by Yungang Wu, P.Geo. and Eugene Puritch, P.Eng, FEC, CET of P&E Mining Consultants Inc, both Independent Qualified Persons as defined by NI 43-101 - Standards of Disclosure for Mineral Projects. The Updated Mineral Resource Estimate was undertaken for pit constrained and out-of-pit nickel, copper, and cobalt Mineral Resources.

The terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are defined in NI 43-101 and recognized by Canadian securities laws but are not defined terms or recognized under U.S. securities laws. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be upgraded to Mineral Reserves. “Inferred Mineral Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an “Inferred Mineral Resource” will ever be upgraded to a higher category. Under Canadian securities laws, estimates of “Inferred Mineral Resources” may not form the basis of Feasibility or Pre-Feasibility studies. U.S. investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable. Accordingly, these Mineral Resource Estimates and related information may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.
