See "Plan of Distribution".

The Common Shares are traded on the TSXV under the symbol "ZEN", and on the Frankfurt Stock Exchange under the symbol "A3C6TM" and are quoted on the OTCQB Venture Market in the United States under the symbol "ZENYF". The Company has also made application to list the Common Shares on the Nasdaq Capital Market ("Nasdaq"). On November 15, 2021, the last trading day prior to the announcement of the Offering, the closing prices of the Common Shares on the TSXV and the OTCQB Venture Market and the Frankfurt Stock Exchange were $7.14, US$5.70 and €4.74, respectively, and on November 19, 2021, the last trading day prior to the filing of this Prospectus, the closing prices of the Common Shares on the TSXV, the OTCQB Venture Market were $6.84, US$5.42 and €4.73, respectively. The Company will apply to list the Common Shares and the Option Shares (as defined herein) issuable pursuant to this Prospectus on the TSXV.

	Price to the Public(1)	Underwriters' Fee(2)	Net Proceeds to the Company(3)
Per Underwriter Share	$5.85	$0.351	$5.499
Per Issuer-Direct Share	$5.85	nil	$5.85
Total(4)	$30,010,172.40	$1,200,069	$28,810,103.40

Notes:

(1)The Offering Price for the Underwriter Shares was determined by arm's length negotiation between the Company and the Underwriters, with reference to the prevailing market price of the Common Shares.

(2)In consideration for the services rendered by the Underwriters in connection with the Underwritten Offering, the Underwriters will be paid a cash fee (the "Underwriters' Fee") equal to 6% of the gross proceeds of the Underwriter Shares under the Offering (including pursuant to any exercise of the Over-Allotment Option, (as defined herein)). No fees are payable to the Underwriters in connection with the issuance and sale of Common Shares to the Issuer-Direct Purchasers (the "Issuer Direct-Offering"), and such purchasers shall waive any and all prospectus liability claims against the Underwriters associated with the purchase by the Issuer-Direct Purchasers of Common Shares pursuant to the Issuer-Direct Offering. See "Plan of Distribution".

(3)As no fee is payable to the Underwriters on any Common Shares purchased by the Issuer-Direct Purchasers (and such purchasers shall waive any and all prospectus liability claims against the Underwriters associated with the purchase by the Issuer-Direct Purchasers of Common Shares pursuant to the Issuer-Direct Offering), the total "Underwriters' Fee" and "Net Proceeds to the Company" have been calculated by excluding the fee of $0.351 per Common Share from the 1,710,944 Common Shares to be purchased by the Issuer-Direct Purchasers in the aggregate. The "Net Proceeds to the Company" also exclude the Company's expenses of the Offering including in connection with the preparation and filing of this Prospectus (estimated to be approximately $300,000), which, together with the Underwriters' Fee, will be paid from the gross proceeds of the Offering.

(4)The Company has granted the Underwriters an option (the "Over-Allotment Option"), exercisable in whole or in part in the sole discretion of the Underwriters at any time and from time to time up to 30 days from and including the Closing Date (as defined herein), to purchase up to an additional 512,850 Common Shares (the "Option Shares") (representing up to 15% of the number of Common Shares sold pursuant to the Underwritten Offering, at the Offering Price, to cover over-allocations, if any, made by the Underwriters and for market stabilization purposes. A person who acquires securities forming part of the Underwriters' over-allocation position acquires those securities under this Prospectus regardless of whether the Underwriters' over- allocation position is ultimately filled through the exercise of the Over-Allotment Option or secondary market purchases. If the Over-Allotment Option is exercised in full, and assuming no fees are paid to the Underwriters in respect of the Issuer-Direct Offering, the total Price to the Public, Underwriters' Fee and Net Proceeds to the Company will be $33,010,344.90, $1,380,079.35 and $31,630,265.55, respectively, before deducting the expenses of the Offering. This Prospectus also qualifies the distribution of the Over-Allotment Option and the issuance of the Option Shares pursuant to the exercise of the Over-Allotment Option. References in this Prospectus to the "Underwriter Shares" includes the Option Shares, and references in this Prospectus to the "Underwritten Offering" includes the Over-Allotment Option, if and to the extent exercised. See "Plan of Distribution" and the table below.

The following table sets out the number of options and other compensation securities that have been issued or may be issued by the Company to the Underwriters and which are exercisable to acquire Common Shares:

Underwriters' Position	Maximum Number of Securities Available	Exercise Period	Exercise Price
Over-Allotment Option(1)	512,850 Option Shares	30 days after and including the Closing Date	$5.85 per Option Share
Total	512,850 Common Shares

Notes:

(1)This Prospectus qualifies the grant of the Over-Allotment Option and the issuance of the Option Shares issuable upon exercise of the Over-Allotment Option. See "Plan of Distribution".

The Underwriters conditionally offer the Underwriter Shares, subject to prior sale, if, as and when issued by the Company and accepted by the Underwriters in accordance with the conditions contained in the Underwriting Agreement referred to under "Plan of Distribution" and subject to the approval of certain legal matters by Irwin Lowy LLP, on behalf of the Company, and by DLA Piper (Canada) LLP, on behalf of the Underwriters.

The Offering Price for the Underwriter Shares offered under this Prospectus and certain other terms of the Underwritten Offering were determined by arm's length negotiation between the Company and Eight. The Underwriters may offer the Underwriter Shares at a price lower than the Offering Price. See "Plan of Distribution". Notwithstanding any such reduction by the Underwriters in the Offering Price, the Company will still receive net proceeds of $5.499 per Underwriter Share purchased by the Underwriters under the Underwritten Offering.

Subscriptions for the Underwritten Offering will be received subject to rejection or allotment in whole or in part, and the right is reserved to close the subscription books at any time without notice. Closing of the Offering is expected to occur on or about December 8, 2021 or such other date as Eight and the Company may agree upon (the "Closing Date"); however, the Underwriter Shares offered pursuant to this Prospectus are to be taken up by the Underwriters, if at all, on or before a date that is not later than 42 days after the date of the receipt for the final short form prospectus. The Common Shares will be issued as non-certificated securities registered in the name of CDS Clearing and Depository Services Inc. ("CDS"), which shall include Common Shares issued to purchasers in the United States that are "qualified institutional buyers" ("Qualified Institutional Buyers") within the meaning of Rule 144A ("Rule 144A") under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and no certificates representing Common Shares will be issued under the Offering, except in certain limited circumstances. A purchaser of Common Shares in the United States that is an "accredited investor" ("U.S. Accredited Investor") within the meaning of Rule 501(a) of regulation D under the U.S. Securities Act will receive definitive physical certificates representing the Common Shares. See "Plan of Distribution" and "Depository Services".

Subject to applicable laws, the Underwriters may, in connection with the Underwritten Offering, over-allot or effect transactions which stabilize or maintain the market price of the Common Shares at levels other than those which might otherwise prevail on the open market. Such transactions, if commenced, may be discontinued at any time. See "Plan of Distribution".

This Prospectus does not constitute an offer to sell or a solicitation of an offer to buy any Common Shares offered by this Prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

The Company has not authorized anyone to provide purchasers with information different from that contained or incorporated by reference in this Prospectus. An investment in the Common Shares is speculative and involves a high degree of risk and must be considered speculative due to the nature of the Company's business and the current stage of operations.

The Company does not intend, and does not assume any obligation, to update any forward-looking statements, other than as required by applicable law. For all of these reasons, prospective investors should not place undue reliance on forward-looking statements.

THE COMPANY

The Company was incorporated as "1774119 Ontario Limited" under the Business Corporations Act (Ontario) on July 29, 2008. On November 24, 2009, the Company filed Articles of Amendment changing the name from "1774119 Ontario Limited" to "Zenyatta Ventures Ltd." On January 16, 2019, the Company filed Articles of Amendment changing the name from "Zenyatta Ventures Ltd." to "ZEN Graphene Solutions Ltd." On October 27, 2021 (effective October 28, 2021), the Company filed Articles of Amendment changing the name from "ZEN Graphene Solutions Ltd." to "Zentek Ltd."

The Company is a reporting issuer in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland.

BUSINESS OF THE COMPANY

The Company commenced operations as a junior mineral exploration company focused primarily on mineral deposits in Northern Ontario, Canada. The Company was actively engaged in exploring mining projects and held an interest in exploration licences on properties in the "Arc of Fire" area in Northern Ontario, Canada. The properties, located north of Lake Superior and west of James Bay in north-western Ontario, Canada, were unpatented, non-contiguous, and consisted of nine claim blocks, including 234 claims comprised of 3,549 claim units over a total of 56,784 ha. Within such claim blocks, the Company still holds a 100% undivided interest in Claim Block 4F, which hosts the igneous- hosted, fluid-derived graphite deposit (the "Albany Graphite Project). The Company did extensive work to determine potential uses for the graphite materials extracted from the Albany Graphite Project, including engaging in testing and studies on graphene materials.

In November 2019, the Company entered into an 18-month exclusive initial option agreement with the University of Guelph for intellectual property regarding an electrochemical exfoliation ("ECE") process to produce graphene oxide ("GO").

In February of 2020, the Company opened a research facility in Guelph, Ontario, to support its university and industrial partners' ongoing research and to scale-up production of graphene product. Subsequently, the COVID-19 pandemic halted research at the Company's collaborators' laboratories. The Company pivoted to focus its resources to develop graphene-based solutions for the fight against COVID-19.

On June 8, 2020, the Company reported that it would be providing GO produced at its facility in Guelph, Ontario using material from the Albany Graphite Project for development of a rapid, ultrasensitive and low-cost biosensor to detect the presence of the SARS-CoV-2 antigen and/or antibodies in COVID-19 suspected patients. This research was funded by an initial grant of approximatively $400,000 from the National Sciences and Engineering Council.

On September 22, 2020 the Company announced, based on the results from a report to the Company dated September 18, 2020 from the ImPaKT Centre at the University of Western Ontario entitled "Zen Graphene - Lab Test Report No. Z03-092020", the development and successful testing of a patent-pending graphene oxide/silver compound that showed to be 99.9% effective against COVID-19 virus a minimum of 35 days after application of the coating to N95 mask material. On December 22, 2020, the Company announced the successful testing at the Department of Microbiology at Mount Sinai Hospital/University Health Network of the graphene oxide/silver compound that showed to be 99.9% effective against both gram-positive and gram-negative aerobic bacteria as well as against fungus/yeast, based on a report to the Company dated December 18, 2020 entitled "Evaluation of Graphene Oxide with Silver Cations (GO-Ag+) as an Antibacterial Agent against Respiratory Pathogens". The Company has filed three patent applications relating to its antimicrobial coating, and on April 13, 2021 announced the brand name ZENGuard™ for such coating.

The Company has entered into a License and Supply Agreement dated September 24, 2021 with Trebor Rx Corp. ("Trebor"), a Canadian manufacturer of personal protective equipment ("PPE") and masks with a production facility located in Collingwood, Ontario, pursuant to which the Company granted a non-exclusive non-transferable license to Trebor to use the Zenguard^TM coating in certain specified Trebor products displaying the Company's branding, including surgical masks, mask filters, nitrile gloves, surgical gowns and scrubs and other healthcare and similar such products, and an exclusive license to sell and distribute ZENGuard™ coated Elastomeric Respirator Mask filters, whether fixed or replaceable, such exclusive license remaining in force only so long as Trebor sells a minimum of 60,000,000 filters per year with annual growth of at least 10%. Trebor agreed to use the ZENGuard™ coating on all of its products sold unless the purchaser specifically refuses to the ZENGuard™ coated products, and agreed to purchase the ZENGuard™ coating from the Company by way of cash payments for a supply based on demand for Trebor products.

- 4 -

To meet anticipated demand for its ZENGuard™ proprietary antimicrobial compound, the Company began sourcing graphene oxide ("GO") from third parties for the production of the ZENGuard™ coating. On November 11, 2021, the Company announced that it had reached an agreement to secure the necessary supply of GO to produce enough ZENGuard™ to coat the equivalent of three billion masks, with shipments scheduled to begin in December 2021 and to continue through the first six months of 2022.

The Company is currently in the process of optimizing the concentration and loading of its antimicrobial GO-silver- based nanomaterial and on PPE equipment (surgical masks, gloves and filters). The Company is also exploring the best coating process to apply its antimicrobial product to the various media/materials to ensure that the coating adheres sufficiently to the fibers and surfaces, achieving a consistent particle dispersion and distribution. The Company conducts its own research and development, including product development and optimization, at its laboratory in Guelph, Ontario, and additionally subcontracts product characterization, efficacy testing (viral, bacterial and fungal), coating performance and imaging, etc. The Company is collaborating closely with a number of meltbown polypropylene nonwoven fabric manufacturers and intends to work towards incorporating coating equipment (spray, pad-dry-cure etc.) into their production lines. The Company has engaged the services of an engineering firm to carry out detailed engineering for a plant to produce GO and GO-silver. This will include process design, mechanical and piping layout, electrical layout, civil/structural/architectural design, control systems and engineering. The engineering firm will also assist on budget pricing and bid evaluation. The intention is for the plant to be designed to be modular (sea can-sized modules) that can be transported to the Company's manufacturing facility in Guelph, Ontario, installed and connected. See "Risk Factors".

Currently the principal markets targeted by the Company are PPE manufacturers (for the use of antimicrobial coatings on surgical masks, filters, cartridges for reusable masks, nitrile gloves, gowns, shoe covers, etc.) and HVAC system manufacturers and suppliers (for the use of antimicrobial coated filters, pre and post-filters, high-efficiency particulate air (HEPA), etc.). The Company is continuing to identify new markets and uses for its graphene-based antimicrobial coating.

The Company works directly with PPE equipment and HVAC filter manufacturers and aims to ultimately supply the antimicrobial coating product directly to the manufacturers for use in their respective production lines, or as pre-coated material/product that will be supplied to manufacturers (e.g., coated polypropylene or polyethylene terathalate meltblown nonwoven media to be used in the construction of a surgical mask, coated nitrile gloves or pre-coated HVAC filtration media). The Company is also actively exploring arrangements with other parties interested in representing the Company and/or distributing its products in other global markets (Europe, India, Australasia, etc.).

Additionally, on June 17, 2021, the Company announced that it had signed an exclusive agreement with McMaster University to be the global commercializing partner for a newly developed aptamer-based, SARS-CoV-2 rapid detection technology. This patent-pending technology is validated with clinical samples from patients recruited under the supervision of two clinicians who also work at McMaster University. The project was funded by the Canadian Institutes of Health Research.

On November 4, 2021, the Company announced that it had been selected as one of three technologies for phase 1 of the Innovation Solutions Canada (ISC) challenge to develop a portable detection device for SARS-CoV-2 in wastewater. The Company received a $148,000 award from ISC to develop its first prototype. The Company, in partnership with Dr. Yingfu Li, Dr. John Brennan, and Dr. Leyla Soleymani at McMaster University and Forsee Instruments Ltd., have been chosen to develop a prototype based on the Company's patent pending aptamer-based saliva sensor to detect SARS-CoV-2 in wastewater samples within the next 4 months. The goal of the ISC challenge, sponsored by the Public Health Agency of Canada and the National Research Council of Canada, is to produce a portable end-to-end SARS-CoV-2 wastewater detection device used for wastewater monitoring and designed to remove delays in the test-to-result pipeline. An additional goal is to provide important outbreak surveillance data to public health units. The challenge is a process whereby one solution that reaches the objectives of the program will receive $350,000 to further develop the prototype into a final, commercial-ready solution.

On November 9, 2021, the Company provided an update on rapid detection technology. The Company contracted with NeoVentures Biotechnology Inc., which has validated the results from the McMaster University team that was described in the Company's press release dated June 17, 2021 against spike proteins and is currently optimizing and simplifying the technology in preparation for regulatory submission and commercial production. The Company contracted with axiVEND to optimize the automated process of producing sensors upon which customized aptamers will be deposited. Through consultation with potential partners and in tandem with McMaster University, the Company developed an improved aptamer with a higher binding affinity for the COVID-19 Delta variant, reduced the three-buffer methodology developed by the McMaster University team to a two-buffer approach to simplify the user experience and optimized the production time of the aptamer-based sensor from 18 hours to 30 minutes with more consistent results.

On November 11, 2021, the Company announced that it had reached an agreement to secure the necessary supply of GO to produce enough ZENGuard™ to coat the equivalent of 3 billion masks with shipments scheduled to begin in December 2021 and continue through the first six months of 2022.

The net proceeds received by the Company pursuant to any exercise of the Over-Allotment Option will be allocated to working capital.

The expected use of net proceeds from the Offering represents the Company's current intentions based upon its present plans and business conditions, which could change in the future as its plans and business conditions evolve. The amounts and timing of the actual use of the net proceeds will depend on multiple factors and there may be circumstances where, for sound business reasons, a reallocation of funds may be necessary in order for the Company to achieve its stated business objectives. The Company may also require additional funds in order to fulfill its expenditure requirements to meet existing and any new business objectives, and the Company may determine to issue additional securities or incur debt to do so. The amount and timing of these expenditures will vary depending on a number of factors, including competitive and technological developments and the rate of growth of the Company's business. As a result, management will retain broad discretion in the application of the net proceeds, and investors will be relying on management's judgment regarding the application of the net proceeds from the Offering. See "Risk Factors".

Pending the use of the net proceeds from the Offering, the Company may plan to invest the net proceeds in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or government securities, or hold them as cash.

During the last financial year the Company had negative operating cash flow because its revenues did not exceed its operating expenses. In addition, as a result of the Company's business plans for the development of its products, the Company expects cash flow from operations to be negative until revenues improve to offset its operating expenditures. The Company's cash flow from operations may be affected in the future by expenditures incurred by the Company to continue to develop its products. The amounts set out above for use as working capital may be used to offset this anticipated negative operating cash flow. See "Risk Factors".

Business Objectives and Milestones

Using the net proceeds of the Offering as set out under "Use of Proceeds" above, the Company intends, over the next twenty-four months, to focus on the development and growth of its GO-silver nanocomposite coating for PPE and potentially other surfaces, as well as continue to develop new intellectual property and products. Specifically, the Company intends to work towards achieving the objectives and milestones set out below (see "Forward-Looking Information").

Acquisition of GO Supply

On November 11, 2021, the Company announced that it had secured a supply of GO sufficient to produce enough ZENGuard™ to coat the equivalent of 3 billion masks with shipments scheduled to begin in December 2021 and continue through the first six months of 2022. The Company has made payments for this order to date, but has additional payment obligations under the purchase order of approximately $1,000,000 over the next six months. The Company believes this supply of GO secured significantly reduces supply risk and will allow the Company to continue to produce its ZENGuard™ coating as the need dictates.

- 9 -

Construction of GO-Silver Nanocomposite Production Plant and Purchase of Coating Equipment

The Company intends to construct a production plant at which it can produce its ZENGuard™ GO-silver nanocomposite coating in house, rather than outsourcing such production. The Company has engaged the services of an engineering firm to carry out detailed engineering for a plant to produce GO-silver. This will include process design, mechanical and piping layout, electrical layout, civil/structural/architectural design, control systems and engineering. The engineering firm will also assist on budget pricing and bid evaluation. The intention is for the plant to be designed to be modular (sea can-sized modules) that can be transported to the Company's manufacturing facility in Guelph, Ontario, installed and connected. The engineering is largely completed to date, and the Company expects the plant construction to be completed in the first quarter of 2022. Additionally, the Company intends to purchase coating machinery and equipment to be used at the production plant, in order for the Company to be able to apply the ZENGuard™ produced onto various materials and products at the same site.

Construction of GO Production Plant

In addition to the construction of a GO-silver production plant discussed above, the Company intends to construct a plant to produce GO over the next fifteen to eighteen months. The Company believes that the ability to produce GO itself rather than relying on third party suppliers of GO will be economically favourable to the Company over the long term, as well as reducing supply and shipping risk.

Strategic Acquisitions

While the Company continues to focus on its existing business, intellectual property and products, the Company intends over the next twenty-four months to explore strategic acquisitions to acquire technology assets or engineering know-how that could aid the Company in its growth, the development of its business, and expedite bringing the Company's products and future products to market. The Company has not entered into definitive agreements in respect of these acquisitions and there can be no assurance that any negotiations will commence, result in definitive agreements or, if they do, what the terms or timing of any acquisition would be or whether these acquisitions will be completed. See "Risk Factors".

Development of Rapid Detection Test Technology

The Company also has an exclusive agreement to be the global commercializing partner for a newly developed, highly scalable, aptamer-based rapid pathogen detection technology.

On June 17, 2021, the Company announced that it had signed an exclusive agreement with McMaster University to be the global commercializing partner for a newly developed aptamer-based, SARS-CoV-2 rapid detection technology. Through consultation with potential partners and in tandem with McMaster University, the Company has developed an improved aptamer with a higher binding affinity for the COVID-19 Delta variant, simplified the user experience, and optimized the production time of the aptamer-based sensor with more consistent results. The Company intends to continue to develop this technology, including the development of software and hardware, using outsourced third party developers. The Company intends to spend funds to bring the product to market as soon as possible, which will require having a working prototype prepared, having conducted baseline studies, and having made application for Health Canada approval of the rapid detection test. In addition, over the next twenty-four months, the Company expects to use funds to develop enhancements and new models of the product.

Building Inventory of Rapid Detection Tests

Contingent on the development of the rapid detection tests and the feedback from Health Canada, the Company intends to allocate funds to the initial inventory orders of rapid detection tests during the 2022 calendar year, once the Company has determined that it is reasonably certain that the product can be brought to market. The Company expects the manufacturing to be outsourced to a third party manufacturer.

Research and Development

In addition to the Company's focus on its existing ZENGuard™ GO-silver nanocomposite coating, and its development of the rapid detection technology discussed above, the Company also intends to spend funds over the next twenty-four months to conduct research and development to explore other potential products and uses, including, but not limited to, using the GO-silver compound in therapeutic applications, fuel additive technology, and ice-phobic technology.

- 10 -

Purchase of Research and Development Facility

The Corporation intends to spend funds acquiring a dedicated location to conduct ongoing research and development activities, enabling the Company to control and adjust the environment within the facility according to the required parameters of the work being conducted.

The Underwriters propose to offer the Common Shares acquired by the Underwriters initially at the Offering Price. After the Underwriters have made a reasonable effort to sell all of such Common Shares at the Offering Price, the Offering Price may be decreased, and the compensation realized by the Underwriters will be decreased by the amount that the aggregate price paid by purchasers for such Common Shares is less than the gross proceeds paid by the Underwriters to the Company. Any such reduction will not affect the net proceeds received by the Company.

The Company will apply to list the Common Shares issuable pursuant to this Prospectus on the TSXV. Listing will be subject to the Company fulfilling all of the listing requirements of the TSXV.

The Common Shares offered hereby have not been and will not be registered under the U.S. Securities Act or any state securities laws and, subject to registration under the U.S. Securities Act and applicable state securities laws or certain exemptions therefrom, may not be offered, sold, transferred, delivered or otherwise disposed of, directly or indirectly, within the United States. The Underwriters have agreed that, except as permitted under the Underwriting Agreement, they will not offer, sell, transfer, deliver or otherwise dispose of, directly or indirectly, the Common Shares at any time within the United States, except pursuant to an exemption from registration under the U.S. Securities Act.

The Underwriting Agreement permits the Underwriters, acting through their registered United States broker-dealer affiliates, to (i) re-offer and re-sell the Common Shares that they have acquired pursuant to the Underwriting Agreement in the United States to Qualified Institutional Buyers in accordance with Rule 144A under the U.S. Securities Act, and (ii) to offer the Common Shares for sale by the Corporation in the United States to substituted purchasers that are U.S. Accredited Investors, in compliance with Rule 506(b) of Regulation D under the U.S. Securities Act, and in each case pursuant to similar exemptions under applicable state securities laws. Moreover, the Underwriting Agreement provides that the Underwriters will offer and sell the Common Shares outside the United States only in accordance with Rule 903 of Regulation S under the U.S. Securities Act. The Common Shares that are sold in the United States will be restricted securities within the meaning of Rule 144(a)(3) of the U.S. Securities Act and may only be offered, sold or otherwise transferred pursuant to certain exemptions from the registration requirements of the U.S. Securities Act.

This Prospectus does not constitute an offer to sell or a solicitation of an offer to buy any of the Common Shares in the United States or to, or for the account or benefit of, U.S. Persons. In addition, until 40 days after the commencement of the Offering, an offer or sale of the Common Shares within the United States or to, or for the account or benefit of, U.S. Persons by any dealer (whether or not participating in the Offering) may violate the registration requirements of the U.S. Securities Act if such offer or sale is made otherwise than in accordance with an exemption from registration under the U.S. Securities Act and similar exemptions under applicable state securities laws.

RISK FACTORS

An investment in the Common Shares is subject to certain risks. Risk factors relating to the Company are discussed in the AIF (on pages 15 through 28), all of which are incorporated by reference in this Prospectus. These risk factors relate to the following: no operating revenues and history of losses, no guarantee of success, intellectual property, lack of revenue from graphene sales, product development and technological change, market development and growth, unpredictable sales cycles, government regulation and import/export controls, industry competition, lack of trading market for graphene, shortages, need for additional funding, no history of operations on mineral property, preliminary economic assessments, single primary asset, estimates of mineral resource risks, infrastructure, property titles, first nations, going concern, commodity markets, market fluctuation and commercial viability, operating hazards and risks, health, safety and community relations, environmental protection, pre-existing environmental liabilities, mining risks and insurance, reliance on key personnel, liquidity risk, share price fluctuations, public health crises such as the COVID-19 pandemic, climate change, conflicts of interest, uninsurable risks, cybersecurity threats, dilution and no dividends.

These risk factors, together with all of the other information included or incorporated by reference in this Prospectus, should be carefully reviewed and considered before a decision is made to invest in the securities offered hereunder. The Company has encountered, and will continue to encounter, risks and uncertainties frequently experienced by growing companies in rapidly changing industries. Additional risks not currently known may also negatively impact the Company's business operations and results of operations. If the Company's assumptions regarding these risks and uncertainties (on which the Company relies in the planning of its business) are incorrect, change due to changes in the Company's markets, or if the Company does not address these risks and uncertainties successfully, the Company's business, prospects, financial condition and results of operations could differ materially from its expectations and/or could be materially and adversely affected. In addition to such risk factors, investors should consider the following additional risks related to the Offering:

Negative Operating Cash Flow

During the financial year ended March 31, 2021 and the interim period ended June 30, 2021, the Company had negative operating cash flow because its revenues did not exceed its operating expenses. In addition, as a result of the Company's business plans for the development of its products, the Company expects cash flow from operations to be negative until revenues improve to offset its operating expenditures. The Company's cash flow from operations may be affected in the future by expenditures incurred by the Company to continue to develop its products. To the extent the Company has negative cash flow in any future period, the Company may be required to use net proceeds from the Offering to fund such negative cash flow from operating activities. In order to stay in business, in the absence of cash flow from operations, the Company will have to raise funding through financing activities. However, there is no certainty the Company will be able to raise funds at all or on terms acceptable to the Company in the event it needs to do so. Furthermore, additional funds raised by the Company through the issuance of equity or convertible debt securities would cause the Company's current shareholders to experience dilution. Such securities also may grant rights, preferences or privileges senior to those of the Company's shareholders. The Company does not have any contractual restrictions on its ability to incur debt and, accordingly, the Company could incur significant amounts of indebtedness to finance its operations. Any such indebtedness could contain restrictive covenants, which likely would restrict the Company's operations.

Uncertainties Relating to the Company's Business Plans

There is no assurance that broad successful commercial applications may be feasible for the Company. The Company is continuing to explore, develop, and test its current products and new products, and there can be no assurance that new uses of existing products or new products will be fully developed for commercial application, that test results will be successful, if completed at all, or that any necessary permits or approvals required in order to market such products will be obtained by the Company.

The Company's business is in part dependent on patents, trade secret and other intellectual property laws of Canada, and potentially foreign jurisdictions. The Company may be unable to prevent third parties from using its intellectual property without its authorization. Some of the Company's current or future technologies and trade secrets may not be covered by any patent or patent application, and the Company's issued and pending patents may not provide the Company with any competitive advantage and could be challenged by third parties. The Company's inability to secure issuance of pending patent applications may limit its ability to protect the intellectual property rights these pending patent applications were intended to cover. The Company's competitors may attempt to design around its patents to avoid liability for infringement and, if successful, could adversely affect the Company's market share. Furthermore, the expiration of the Company's patents may lead to increased competition.

Additionally, the Company plans to construct facilities for some of its operations and business activities. There can be no assurance that locations will be secured on terms favourable to the Company or at all, that engineering plans will be completed or will be satisfactory for the intended business activities of the Company, or that construction of such facilities will be completed. If such facilities are not constructed, there could be a material adverse effect of the Company's planned business and operations.

Listing Application in the United States

The Company has applied to list its Common Shares on Nasdaq in the United States, and such listing will be subject to the Company fulfilling all of the listing requirements of Nasdaq. The Company cannot provide assurances listing on Nasdaq will be completed, or that an active trading market will develop in the United States or will be sustained if listed.

Unallocated Proceeds of the Offering

The Company intends to use the net proceeds of the Offering (the "Offering Proceeds") in the manner described under the heading "Use of Proceeds". However, the Company's management will have broad discretion concerning the use of the Offering Proceeds as well as the timing of their expenditures, and there can be no assurance as to how the funds will be allocated. The failure of the Company to apply these funds effectively could negatively impact the success of the Company's business.

Until utilized, the Offering Proceeds will be held in cash balances in the Company's bank account or invested at the discretion of the directors of the Company. As a result, a purchaser will be relying on the judgment of management of the Company for the application of the Offering Proceeds. The results and the effectiveness of the application of the Offering Proceeds are uncertain. If the Offering Proceeds are not applied effectively, the Company's business, prospects, financial condition and results of operations may suffer, which could have material and adverse effect on the trading price of the Common Shares in the market.

Dilution

While the net proceeds of the Offering are expected to enhance the Company's liquidity, to the extent that a portion of the net proceeds of the Offering remains as cash, the Offering may dilute the interest of holders of Common Shares. In the future, the Company may raise funds through the sale of additional Common Shares or securities convertible or exchangeable into or exercisable for Common Shares. Any such issuances may dilute the interests of the then- current holders of Common Shares and may have a negative impact on the market price of the Common Shares.

TRANSFER AGENT AND REGISTRAR

Effective as of November 22, 2021, the registrar and transfer agent of the Company is TSX Trust Company, having an address of 100 Adelaide Street West, Suite 301, Toronto, Ontario M5H 1S3.

STATUTORY AND CONTRACTUAL RIGHTS OF WITHDRAWAL AND RESCISSION

Securities legislation in certain of the provinces of Canada provides purchasers with the right to withdraw from an agreement to purchase securities. This right may be exercised within two business days after receipt or deemed receipt of a prospectus and any amendment. In several of the provinces of Canada, the securities legislation further provides a purchaser with remedies for rescission or, in some jurisdictions, revision of the price or damages if the prospectus and any amendment contains a misrepresentation or is not delivered to the purchaser, provided that the remedies for rescission, revision of the price or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of these rights or consult with a legal advisor.
