Resource Estimates

CLASS 1 NICKEL REPORTS UPDATED NI 43-101 MINERAL RESOURCE ESTIMATE

ON ITS ALEXO-DUNDONALD NI-CU-CO DEPOSITS, TIMMINS, ONTARIO

1.25 M Indicated Tonnes at 1.0% Ni and 1.01 M Inferred Tonnes at 1.1% Ni

Toronto, Ontario (November 2, 2020) – Class 1 Nickel and Technologies Ltd. (CSE:NICO) ("Class

1" or the "Company") is pleased to report an updated National Instrument 43-101 Mineral Resource

Estimate 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 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 approximately 20 square km land package (Figure 1).

A large portion of the Property remains untested by drilling and modern geophysics.

Following the completion of a modern Mineral Resource validation program and a Technical Report of

the Mineral Resources contained within the newly amalgamated Alexo and Dundonald deposit models,

Class 1 is reporting an updated total estimated Indicated Mineral Resource of 1.25 Million tonnes (Mt)

with an average grade of 0.99% Ni and a total estimated Inferred Mineral Resource of 1.01 Mt with an

average grade of 1.08% Nickel (Table 1). The total estimated Indicated Mineral Resource has increased

by 119% and the Inferred Mineral Resource has increased by 1,400% since the previously reported

Mineral Resource Estimate contained in the NI 43-101 compliant Technical Report dated June 30, 2020.

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 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.

The October 24, 2020 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 done 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 total Indicated Mineral Resource based on a Net Smelter Return (NSR) for the

out-of-pit Mineral Resource is 1.25 Mt at 0.99%, 0.04% Cu and 0.02% Co for a total of 27.35 Mlbs of

contained nickel. An additional 1.0 Mt at 1.08% Ni, 0.03% Cu and 0.02 Co (23.90 Mlbs contained nickel)

were calculated as the Inferred Mineral Resource.

In addition, Class 1 recently completed a modern VTEM™ plus time-domain airborne electromagnetic

survey over the 20 km2 square land package, the first modern geophysical survey of this kind over the

Property. The Company looks forward to updating the market with the results of this survey when expert

analysis and targeting is completed, and recommendations have been made.

The Company is in the process of planning its near-term surface exploration program to include a

diamond drilling program aimed at testing priority mag-EM targets generated from the recently

completed VTEM survey. In addition, the Company will be planning step-out and expansion drilling

programs to potentially increase the size and grade of the current Mineral Resource, moving the project

toward an eventual Preliminary Economic Assessment (“PEA”) in order to examine the possibility of direct

shipping nickel production.

Figure 1: Alexo-Dundonald Project Map

The Alexo-Dundonald Class 1 Nickel Project sits on a 14 km strike-length, folded komatiite unit containing

several nickel-copper-cobalt and platinum-group element Mineral Resources. Decades of successful

capital expenditure and investment into the Project by previous owners has resulted in the discovery

and delineation of four main nickel Mineral Resources that occur along the folded komatiite unit. A total

of 102,883 metres of drilling has been conducted on and around the komatiite fold and a valuable data

set has been assembled, which confirms the existence of numerous other smaller high-grade deposits

and mineralized lenses that occur between and alongside the four main Updated Mineral Resources

reported herein.

Eugene Puritch, P.Eng, FEC, CET, President of P&E, heads a specialist Mineral Resource and Mine

Engineering consulting firm that has successfully built mine plans for several Canadian mining companies

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

Preliminary Economic Assessment that P&E will soon commence is being designed around similar

principles.”

Small-scale open pit mining of Nickel and direct shipping mineralized material production at Alexo-

Dundonald last occurred in 2004-2005. Subsequently in 2011, more mining and stockpiling of mineralized

material occurred in conjunction with the signing of a custom processing agreement with Glencore’s

Strathcona process facility near Sudbury.

This analysis will be used to couple with deeper penetrating ground geophysics prior to commencing

step-out and expansion drilling aimed at adding more tonnage to the overall Mineral Resource. After the

completion of the diamond drilling campaign, the Company will produce a PEA inclusive of a mine and

production plan with a view to re-initiating the direct shipping operation.

Class 1 President Mr. Benjamin H Cooper stated “This Project has indicated the viability of a direct

shipping model on several occasions in the past. This time we are operating in a rising class 1 nickel

market with truly global demand and our Company is envisioning a much bolder, larger, stronger

approach utilizing greater financial backing and capacity with a plan to ship more mineralized material,

faster and more efficiently than previously possible. This approach is anticipated to fund deeper drilling

and a systematic Mineral Resource expansion to scale-up production.

Tony Donaghy, Class 1 adviser and consultant for CSA Global confirmed “The Alexo-Dundonald Project

has the potential of a rapid turnaround to production turnkey operation that has the ability to increase

more new nearby nickel sulphide discoveries and grow the Mineral Resource base to allow for a

diversified restart.”

The advanced permitting status, close to surface high grade mineralization, and direct shipping mining

model fits nicely into the local infrastructure of Sudbury-Timmins thus allowing Class 1 to avoid any need

for high start-up capital costs. Additionally, there is also untested potential at depth.

“International exploration for similar komatiite-hosted nickel sulphide systems in Australia, as well as

within systems such as Thompson and Raglan in Canada, has demonstrated that there is good potential

for exploration and discovery of continued and/or additional sulphide mineralization along strike/plunge

within mineralized channelized flow. The shallow nature of previous exploration and the tight focus on

the near-surface known mineralization at Alexo-Dundonald means these possibilities have not yet been

tested on the Project.”, Mr Donaghy said.

P&E’s Senior Associate Geologist, William Stone, Ph.D, P,Geo. Stated “The Alexo-Dundonald host rocks

are part of a regional geophysical trend that extends tens of kilometres westward and includes the giant

Kidd-Creek base metal VMS mine and even the Montcalm nickel mine, 100 km away. This regional trend

corresponds to the komatiite-bearing Kidd-Munro assemblage, which has been subject to very little

modern airborne electromagnetic surveys and systematic mineral exploration for nickel sulphide

deposits. Consequently, the potential for discovery of additional nickel sulphide deposits under cover

along this favourable trend remains high”.

Most Recent 2011 Metallurgical Testwork

In 2011, Xstrata Process Support (Xstrata) – formerly Falconbridge, now Glencore Nickel –

at its laboratories in Falconbridge near Sudbury, Ontario, performed scoping level

metallurgical testing and quantitative mineralogy for the Alexo South project. The scope

included a custom flowsheet assessment and quantitative mineralogy using EPMA

microprobe assessment.

The Alexo North and Alexo South Mineral Resources extend along strike and

depth and down plunge and will be extension drilled to add more tonnage to

the current NI 43-101 Mineral Resource Estimate. The majority of drilling and

mining in the past 30 years has been shallow work (less than 100 m vertical

depth below surface.
