Resource Estimates Technical Reports (NI 43-101)

CLASS 1 NICKEL FILES ALEXO-DUNDONALD TECHNICAL REPORT ON SEDAR

Toronto, Ontario (December 17, 2020) – Class 1 Nickel and Technologies Ltd. (CSE:NICO)

("Class 1" or the "Company") is pleased to announce it has filed an updated Alexo -Dundonald

National Instrument NI 43-101 Technical Report on SEDAR for its 100% owned Alexo-Dundonald

Nickel Project (the “Project” or the “Property”) located about 45 km northeast of Timmins,

Ontario. The Technical Report supports the updated Mineral Resource Estimate press releases of

November 2 and December 1, 2020.

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 (ba salt and komatiite flows) rocks that trend through the strategic land package

(Figure 2). A large portion of the Property remains untested by drilling.

Class 1 President Mr. Benjamin H Cooper stated “We are pleased to disclose the Technical Report

on SEDAR that contains the details of our recently announced updated Mineral Resource Estimate

and describes the Project upside potential. This is the first step on our path to undertaking a

Preliminary Economic Assessment which is scheduled to commence upon completion of an

upcoming Q1 2021 drilling program currently being planned.”

Class 1 is now reporting an updated total estimated Indicated Mineral Resource of 1.25 Mt

with an average grade of 0.99% and an Inferred Mineral Resource of 2.01 Mt with an

average grade of 1.0 1% Nickel (Table 1) and an. Details of the current pit -constrained and

out-of-pit Mineral Resources are provided in Table 2.

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 th at 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.

The Updated December 2, 2020 NI 43-101 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 total Indicated Mineral Resource Estimate

based on NSR cut-off values of CDN$30 per tonne for the pit constrained Mineral Resource and

CDN$90 per tonne for the out-of-pit Mineral Resource.

The Alexo-Dundonald Project was previously mined via a direct shipping model, and the 2021

Preliminary Economic Assessment that the Company plans to undertake will be designed around

similar principles.

The Updated Mineral Resource Estimate was completed by P&E Mining Consultants Inc (“P&E”)

and has been reviewed internally by the Company. The full NI 43-101 Technical Report in respect

Cautionary Note to U.S. Investors Concerning Estimates of Mineral Resources

These Mineral Resource Estimates have been prepared in accordance with the requirements of Canadian securities

laws, which differ from the requirements of U.S. securitie s laws. 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. securitie s 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 rel ated 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.
