EXPLANATORY NOTE

PolyMet Mining Corp. (the "Company" or "PolyMet") is a Canadian issuer eligible to file its Annual Report pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), on Form 40-F pursuant to the multi-jurisdictional disclosure system of the Exchange Act. The Company is a "foreign private issuer" as defined in Rule 3b-4 under the Exchange Act. Equity securities of the Company are accordingly exempt from Sections 14(a), 14(b), 14(c), 14(f) and 16 of the Exchange Act pursuant to Rule 3a12-3.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 40-F (this "Annual Report") contains statements that constitute "forward-looking statements" within the meaning of Section 27A of the Securities Exchange Act of 1934 and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Forward-looking statements are not, and cannot be, a guarantee of future results or events. Forward looking statements are based on, among other things, opinions, assumptions, estimates and analyses that are subject to significant risks, uncertainties, contingencies and other factors that may cause actual results and events to be materially different from those expressed or implied by the forward-looking statement.

All statements in this Annual Report that address events or developments that PolyMet expects to occur in the future are forward-looking statements and are generally, although not always, identified by words such as "expect", "plan", "anticipate", "project", "target", "potential", "schedule", "forecast", "budget", "estimate", "intend" or "believe" and similar expressions or their negative connotations, or that events or conditions "will", "would", "may", "could", "should" or "might" occur.

These forward-looking statements include, but are not limited to, PolyMet's objectives, strategies, intentions, expectations, including the need for copper and other products and commodities that the Company will produce and sell, production, costs and inflationary impacts, capital and exploration expenditures, including estimated economics of future financial and operating performance, expected receipt of regulatory approvals and the expected timing thereof, expected receipt or completion of feasibility studies and other studies and the expected timing thereof, the anticipated benefits of the 50:50 joint arrangement transaction (the "Joint Arrangement") with Teck American, Inc., a subsidiary of Teck Resources Limited (together "Teck") and the Company's expectations with respect to the future development of the NorthMet and Mesaba projects; the timing and closing of the financings required pursuant to the Joint Arrangement, proposed or expected changes in regulatory frameworks and their anticipated impact on the Company's business, and impacts on the Company's environmental, community, health and safety initiatives. All forward-looking statements in this Annual Report are qualified by this cautionary note.

The material factors or assumptions applied in drawing the conclusions or making forecasts or projections set in the forward-looking statements include, but are not limited to:

 various economic assumptions, in particular, commodity price and capital cost estimates;

 certain operational assumptions, including mill recovery, operating scenarios;

 construction costs and schedules; and

 assumptions related to timing and certainty of the environmental review and permitting process.

The risks, uncertainties, contingencies and other factors that may cause actual results and events to differ materially from those expressed or implied by the forward-looking statement may include, but are not limited to, risks generally associated with the mining industry, such as: economic factors (including future commodity prices, currency fluctuations, inflation rates, energy prices and general cost escalation); uncertainties related to the development of the NorthMet and Mesaba projects; dependence on key personnel and employee relations; risks relating to political and social unrest or change, operational risk and hazards, including unanticipated environmental, industrial and geological events and developments and the inability to insure against all risks; failure of plant, equipment, processes, transposition and other infrastructure to operate as anticipated; compliance with governmental and environmental regulations, including permitting requirements; the outcome of ongoing litigation in connection with permits and decisions for the NorthMet and Mesaba projects; the potential impact of COVID-19 and its variants on PolyMet, as well as other factors identified and as described in more detail under the heading "Risk Factors" in Item 5 of the Annual Information Form filed as Exhibit 99.1 to this Annual Report. The list is not exhaustive of the factors that may affect the forward-looking statements.

1


There can be no assurance that such statements will prove to be accurate, and actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements. Accordingly, no assurance can be given that any events anticipated by the forward-looking statements will transpire or occur, or if any of them do, what benefits or liabilities PolyMet will derive therefrom. The forward-looking statements reflect the current expectations regarding future events and operating performance and speak only as of the date hereof and PolyMet does not assume any obligation to update the forward-looking statements if circumstances or management's beliefs, expectations or opinions should change other than as required by applicable law. For the reasons set forth above, undue reliance should not be placed on forward-looking statements.

CAUTIONARY NOTE TO UNITED STATES READERS REGARDING

RESOURCE AND RESERVE ESTIMATES

The Company's Annual Information Form for the year ended December 31, 2022 is filed as Exhibit 99.1 to this Annual Report and the Company's Management's Discussion and Analysis for the years ended December 31, 2022 and 2021 is filed as Exhibit 99.3 to this Annual Report. These documents have been prepared in accordance with requirements of the securities laws in effect in Canada, which differ from requirements of United States securities laws.

Mineral reserves and mineral resources presented in this Annual Report have been estimated in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), as required by Canadian securities regulatory authorities. In accordance with NI 43-101, the Company uses the terms mineral reserves and resources as they are defined in accordance with the CIM Definition Standards on mineral reserves and resources ("CIM") adopted by the Canadian Institute of Mining, Metallurgy and Petroleum.

The United States Securities and Exchange Commission ("SEC") has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended. These amendments became effective February 25, 2019 (the "SEC Modernization Rules") with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7 ("Guide 7"), which was rescinded from and after the required compliance date of the SEC Modernization Rules. As a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the multi-jurisdictional disclosure system ("MJDS"), the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101. However, if the Company either ceases to be a "foreign private issuer" or ceases to be entitled to file reports under the MJDS and the CIM Definition Standards, then the Company will be required to provide disclosure on its mineral properties under the SEC Modernization Rules. Accordingly, United States investors are cautioned that the disclosure the Company provides on its mineral properties in this Annual Report on Form 40-F and under its continuous disclosure obligations under the Exchange Act may be different from the disclosure that the Company would otherwise be required to provide as a U.S. domestic issuer or a non-MJDS foreign private issuer under the SEC Modernization Rules.

The SEC Modernization Rules include the adoption of terms describing mineral reserves and mineral resources that are substantially similar to the corresponding terms under the CIM. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured", "indicated" and "inferred" mineral resources. In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to the corresponding CIM definitions, as required by NI 43-101.

United States investors are also cautioned that while the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", investors should not assume that any part or all of the mineral deposits in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility. Accordingly, United States investors are cautioned not to assume that any "measured mineral resources", "indicated mineral resources", or "inferred mineral resources" of PolyMet are or will be economically or legally mineable. Further, "inferred mineral resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. In accordance with Canadian rules, estimates of "inferred mineral resources" cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.

2


Accordingly, information contained in this Annual Report and the documents incorporated by reference herein that contain descriptions of the Company's mineral deposits may not be comparable to similar information made by public United States companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

CAUTIONARY NOTE TO UNITED STATES READERS REGARDING

DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted, under the multi-jurisdictional disclosure system adopted by the SEC, to prepare this Annual Report in accordance with Canadian disclosure requirements, which differ from those of the United States. The Company has prepared its financial statements, which are filed as Exhibit 99.2 to this Annual Report, in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). The Company's financial statements may not be comparable to financial statements of other United States companies. Since the Company has prepared its financial statements in accordance with IFRS as issued by the IASB, it is not required to provide a reconciliation to United States generally accepted accounting principles.

ANNUAL INFORMATION FORM

The Company's Annual Information Form for the year ended December 31, 2022 is filed as Exhibit 99.1 to this Annual Report and is incorporated by reference herein.

AUDITED ANNUAL FINANCIAL STATEMENTS

The audited consolidated financial statements of the Company for the years ended December 31, 2022 and 2021, including the report of the Company's independent registered public accounting firms with respect thereto, are filed as Exhibit 99.2 to this Annual Report and incorporated by reference herein.

MANAGEMENT'S DISCUSSION AND ANALYSIS

The Company's Management's Discussion and Analysis for the years ended December 31, 2022 and 2021, is filed as Exhibit 99.3 to this Annual Report and incorporated by reference herein.

DISCLOSURE CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company's Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") have evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13(a)-15(e) and 15(d)-15(e) under the Exchange Act as of the end of the period covered by this Annual Report (the "Evaluation Date").

Based on such evaluation, such officers have concluded that, as of the Evaluation Date, the Company's disclosure controls and procedures are effective. Such disclosure controls and procedures are designed to ensure that the information required to be disclosed by the Company in reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms, and includes controls and procedures designed to ensure information relating to the Company required to be included in reports filed or submitted under the Exchange Act is accumulated and communicated to the Company's management to allow timely decision regarding disclosure.

INTERNAL CONTROLS OVER FINANCIAL REPORTING

Management's Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Consolidated Financial Statements for external reporting purposes in accordance with IFRS as issued by IASB.

3


Internal control over financial reporting, no matter how well designed, has inherent limitations. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management has assessed the effectiveness of internal controls over financial reporting as at December 31, 2022. In making its assessment, management has used the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") to evaluate internal controls over financial reporting. Based on this assessment, management has concluded that the Company's internal controls over financial reporting was effective as at that date.

Attestation Report of the Independent Registered Public Accounting Firm

The effectiveness of the Company's internal control over financial reporting as at December 31, 2022, has been audited by Deloitte & Touche LLP, the Company's independent registered public accounting firm, as stated in their report included in Exhibit 99.2 to this Annual Report.

Changes in Internal Controls

There have been no changes in the Company's internal control over financial reporting during the period covered by this Annual Report that have materially affected, or is reasonably likely to material affect, the Company's internal control over financial reporting.

CORPORATE GOVERNANCE

The Company is listed on the Toronto Stock Exchange ("TSX") and is required to describe its practices and policies with regards to corporate governance with specific reference to TSX guidelines by way of an annual corporate governance statement in the Company's annual report or information circular filed with the appropriate securities regulators in Canada.

The Company is also listed on the NYSE American and additionally complies as necessary with the rules and guidelines of the NYSE American and SEC.

The Company reviews its governance practices on an ongoing basis to ensure it is in compliance with all applicable requirements. The Company is a "controlled company" (as defined by the NYSE) of which more than 50% of the voting power is held by an individual, group or another company and therefore exempt from certain corporate governance requirements.

The Company's Board of Directors is responsible for the Company's Corporate Governance policies and has determined that during 2022 all the members of the Audit Committee were independent (as required by applicable law), based on the criteria for independence and un-relatedness prescribed by the TSX and Section 803A of the NYSE American Company Guide. The Compensation, and Nominating & Corporate Governance Committees each have a majority of independent directors. The Board of Directors believes it is appropriate for directors who are not considered to be independent to sit on these committees to bring the knowledge and perspective of the controlling shareholder to executive compensation, appointments and board nominations.

Controlled Company

The Company's Common Shares are listed on the NYSE American. Under the rules of the NYSE American, the Company is considered a "controlled company" because Glencore AG holds more than 50% of the voting power of the Company. As a "controlled company," the Company is exempt from certain rules and requirements of the NYSE American related to corporate governance matters, including the rules requiring that (i) the Company's Board of Directors be comprised of at least a majority of independent directors, (ii) the compensation of the Company's executive officers be determined, or recommended to the Board of Directors for determination, either by a compensation committee comprised of independent directors or by a majority of the independent directors, and (iii) nominations for election to the Company's Board of Directors be either selected, or recommended for the Board of Directors' selection, by either a nominating committee comprised solely of independent directors or by a majority of the independent directors.

4


NYSE AMERICAN CORPORATE GOVERNANCE

The Company's common shares are listed on the NYSE American under the trading symbol "PLM". Section 110 of the NYSE American Company Guide permits the NYSE American to consider the laws, customs and practices of foreign issuers in relaxing certain NYSE American listing criteria, and to grant exemptions from NYSE American listing criteria based on these considerations. A description of the significant ways in which the Corporation's governance practices differ from those followed by domestic companies pursuant to NYSE American standards is as follows:

Shareholder Approval Requirements: NYSE American requires a listed company to obtain the approval of its shareholders for certain types of securities issuances, including the issuance of common shares of the Company to directors of the Company in a private placement transaction at a price per Unit that is less than the market value of the common shares of the Company on the date of the definitive agreement of the offering. The Company sought and received a waiver from NYSE American's shareholder approval requirements in circumstances where the securities issuance does not trigger such a requirement under the rules of the TSX.

In addition, the Company may from time-to-time seek relief from NYSE American corporate governance requirements on specific transactions under Section 110 of the NYSE American Company Guide by providing written certification from independent local counsel that the non-complying practice is not prohibited by the Company's home-country law, in which case, the Company shall make the disclosure of such transactions available on its website at www.polymetmining.com. Information contained on the website of the Company is not part of this Annual Report.

AUDIT COMMITTEE

Composition and Responsibilities

The Company's Board of Directors has a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act and Section 803B of the NYSE American Company Guide.

During 2022, the Company's Audit Committee was composed of David J. Fermo, Dr. David Dreisinger, and Alan R. Hodnik, each of whom, in the opinion of the Company's Board of Directors, was independent as determined under the rules of the TSX and Rule 10A-3 of the Exchange Act, Section 803A of the NYSE American Company Guide and each of whom is financially literate. The Audit Committee meets the composition requirements set forth by Section 803B(2) of NYSE American Company Guide.

The members of the Audit Committee do not have fixed terms and are appointed and replaced from time to time by the Board of Directors.

The Audit Committee meets four times a year, at a minimum, and has access to all officers, management and employees of the Company and may engage advisors or counsel as deemed necessary to perform its duties and responsibilities as a committee.

The Audit Committee meets with the Company's President and CEO, the Company's CFO, and the Company's independent auditors to review and inquire into matters affecting financial reporting, the system of internal accounting and financial controls, and the Company's audit procedures and audit plans. The Audit Committee also recommends to the Board of Directors the independent auditors to be appointed for each year. In addition, the Audit Committee reviews and recommends to the Board of Directors for approval the annual and quarterly financial statements and management's discussion and analysis. Finally, the Audit Committee undertakes other activities as required by the rules and regulations of the TSX and the NYSE American and other governing regulatory authorities.

The full text of the Audit Committee Charter is set forth in the Company's Annual Information Form incorporated by reference in this Annual Report.

5


Audit Committee Financial Expert

During 2022, the Board of Directors determined that David J. Fermo qualified as the Audit Committee's "financial expert" as defined in Item 407(d)(5)(ii) of Regulation S-K under the Exchange Act and was "financially sophisticated" as determined under Section 803(B)(2)(iii) of the NYSE American Company Guide. Mr. Fermo qualifies as a financial expert and is financially sophisticated, in that he has an understanding of generally accepted accounting principles and financial statements; is able to assess the general application of accounting principles in connection with the accounting for estimates, accruals and reserves; has experience analyzing or evaluating financial statements that entail accounting issues of equal complexity to the Company's financial statements (or actively supervising another person who did so); and has a general understanding of internal controls and procedures for financial reporting and an understanding of audit committee functions.

MINE SAFETY DISCLOSURE

Pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 ("Dodd-Frank Act"), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities under the regulation of the Federal Mine Safety and Health Administration ("MSHA") under the Federal Mine Safety and Health Act of 1977 ("Mine Act"). This required information is filed as Exhibit 99.4 to this Annual Report.

DISCLOSURE PURSUANT TO SECTION 219 OF THE IRAN THREAT

REDUCTION & SYRIA HUMAN RIGHTS ACT

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 ("ITRA"), effective August 10, 2012, added a new subsection (r) to Section 13 of the Exchange Act, which requires issuers that file periodic reports with the SEC to disclose in their annual and quarterly reports whether, during the reporting period, they or any of their "affiliates" (as defined in Rule 12b-2 under the Exchange Act) have knowingly engaged in specified activities or transactions relating to Iran, including activities not prohibited by U.S. law and conducted outside the U.S. by non-U.S. affiliates in compliance with applicable laws. Issuers must also file a notice with the SEC if any disclosable activity under ITRA has been included in an annual or quarterly report.

Because the SEC defines the term "affiliate" broadly, our largest shareholder may be considered an affiliate of the Company despite the fact that the Company has no control over its largest shareholder's actions or the actions of its affiliates. As such, pursuant to Section 13(r)(1)(D)(iii) of the Exchange Act, the Company hereby discloses the following information provided by our largest shareholder regarding transactions or dealings with entities controlled by the Government of Iran ("the GOI"):

During January 1, 2022 until December 31, 2022, a non-U.S. affiliate of the largest shareholder of the Company ("the non-U.S. Shareholder Affiliate") entered into sales contracts for agricultural products with, or for delivery to or from Iranian entities wholly or majority owned by the GOI. The non-U.S. Shareholder Affiliate performed its obligations under the contracts in compliance with applicable sanctions laws and, where required, with the necessary prior approvals by the relevant governmental authorities.

The gross revenue of the non-U.S Shareholder Affiliate related to these contracts did not exceed the value of USD $1.365 billion for the year ended December 31, 2022.

The non-U.S. Shareholder Affiliate does not allocate net profit on a country-by-country or activity-by-activity basis, but estimates that the net profit attributable to the contracts would not exceed a small fraction of the gross revenue from such contracts. It is not possible to determine accurately the precise net profit attributable to such contracts.

The contracts disclosed above do not violate applicable sanctions laws administered by the U.S. Department of the Treasury, Office of Foreign Assets Control, and are not the subject of any enforcement action under Iran sanction laws.

The non-U.S. Stockholder Affiliates expect to continue to engage in similar activities in the future in compliance with applicable economic sanctions and in conformity with U.S. secondary sanctions.

Neither the Company nor any of its subsidiaries (i) engaged in any transactions or activities requiring disclosure under ITRA nor (ii) were involved in the transactions described in this section. As of the date of this report, the Company is not aware of any other activity, transaction or dealing by us or any of its affiliates during the fiscal year ended December 31, 2022 that requires disclosure in this report under Section 13(r) of the Exchange Act.
