PRINCIPAL DOCUMENTS

The following documents, filed as Exhibits 99.1 through 99.3 hereto, are hereby incorporated by reference into this Annual Report on Form 40-F of Western Copper and Gold Corporation (the "Company" or the "Registrant"):

(a) Annual Information Form for the fiscal year ended December 31, 2022;

(b) Management's Discussion and Analysis of Financial Condition and Results of Operations for the fiscal year ended December 31, 2022; and

(c) Audited Annual Consolidated Financial Statements for the years ended December 31, 2022 and 2021 and notes thereto, together with the Report of Independent Registered Public Accounting Firm thereon.

Our independent auditor is PricewaterhouseCoopers LLP, Vancouver, British Columbia, Canada (PCAOB Firm ID 271).

The Company's Audited Consolidated Financial Statements included in this Annual Report on Form 40-F have been prepared in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board. Therefore, they are not comparable in all respects to financial statements of United States companies that are prepared in accordance with United States generally accepted accounting principles.

ADDITIONAL DISCLOSURE

Resource and Reserve Estimates

The Company's Annual Information Form for the fiscal year ended December 31, 2022, which is attached hereto as Exhibit 99.1, has been prepared in accordance with the requirements of the securities laws in effect in Canada as of December 31, 2022, which differ in certain material respects from the disclosure requirements of United States securities laws. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The definitions of these terms differ from the definitions of such terms for purposes of the disclosure requirements of the Securities and Exchange Commission (the "Commission").

Accordingly, information contained and incorporated by reference into this Annual Report on Form 40-F that describes the Company's mineral deposits may not be comparable to similar information made public by issuers subject to the Commission's reporting and disclosure requirements applicable to domestic United States issuers.

Certifications and Disclosure Regarding Controls and Procedures.

(a) Certifications. See Exhibits 99.4, 99.5, 99.6 and 99.7 to this Annual Report on Form 40-F.

(b) Disclosure Controls and Procedures. As of the end of the Company's fiscal year ended December 31, 2022, an evaluation of the effectiveness of the Company's "disclosure controls and procedures" was carried out by the Company's management with the participation of the Chief Executive Officer and Chief Financial Officer, who are the principal executive officer and principal financial officer of the Company, respectively. Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that as of the end of that fiscal year, as a result of the material weakness identified during the Company's assessment of its internal control over financial reporting, the Company's disclosure controls and procedures are not effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Commission rules and forms and (ii) accumulated and communicated to the Company's management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

(c) Management's Annual Report on Internal Control Over Financial Reporting.

The required disclosure is included in "Management's Report on Internal Control Over Financial Reporting" that accompanies the Company's Consolidated Financial Statements for the fiscal year ended December 31, 2022, filed as Exhibit 99.3 to this Annual Report on Form 40-F.

(d) Attestation Report of the Registered Public Accounting Firm.  

This Annual Report on Form 40-F does not include an attestation report of the Company's registered public accounting firm because the Company qualified as an Emerging Growth Company pursuant to Section 2(a)(19) of the Securities Act of 1933 during the year covered by this Annual Report on Form 40-F, and this Annual Report is therefore not required to include such an attestation report.

(e) Changes in Internal Control Over Financial Reporting.

The required disclosure is included in the "Management's Report on Internal Control Over Financial Reporting" that accompanies the Company's Consolidated Financial Statements for the fiscal year ended December 31, 2022, filed as Exhibit 99.3 to this Annual Report on Form 40-F.

Notices Pursuant to Regulation BTR.

NYSE American Statement of Governance Differences.

As a Canadian corporation listed on the NYSE American, the Company is not required to comply with most of the NYSE American corporate governance standards, so long as the Company complies with Canadian corporate governance practices. In order to claim such an exemption, however, Section 110 of the NYSE American Company Guide requires that the Company provide to NYSE American written certification from independent Canadian counsel that the non-complying practice is not prohibited by Canadian law. In addition, the Company must disclose the significant differences between its corporate governance practices and those required to be followed by U.S. domestic issuers under the NYSE American's corporate governance standards.

The Company has included a description of such significant differences in corporate governance practices on its website: www.westerncopperandgold.com. In addition, the Company has included a description of such significant differences below:

Shareholder Meeting Quorum Requirement: The NYSE American minimum quorum requirement for a shareholder meeting is one-third of the outstanding common shares. In addition, a company listed on NYSE American is required to state its quorum requirement in its bylaws. The Company's quorum requirement is set forth in its Articles and bylaws. A quorum for a meeting of shareholders of the Company is one person of the outstanding common shares present or represented by proxy.

Shareholder Approval Requirement: The Company will follow Toronto Stock Exchange rules for shareholder approval of new issuances of its common shares. Following Toronto Stock Exchange rules, shareholder approval is required for certain issuances of shares that: (i) materially affect control of the Company; or (ii) provide consideration to insiders in aggregate of 10% or greater of the market capitalization of the listed issuer and have not been negotiated at arm's length. Shareholder approval is also required, pursuant to Toronto Stock Exchange rules, in the case of private placements: (i) for an aggregate number of listed securities issuable greater than 25% of the number of securities of the listed issuer which are outstanding, on a non-diluted basis, prior to the date of closing of the transaction if the price per security is less than the market price; or (ii) that during any six month period are to insiders for listed securities or options, rights or other entitlements to listed securities greater than 10% of the number of securities of the listed issuer which are outstanding, on a non-diluted basis, prior to the date of the closing of the first private placement to an insider during the six month period.

Equity Compensation Plan Approval Requirements: Section 711 of the NYSE American's Listed Company Guide requires shareholder approval of all equity compensation plans and material revisions to such plans. The definition of "equity compensation plans" covers plans that provide for the delivery of both newly issued and treasury securities, as well as plans that rely on securities re-acquired in the open market by the issuing company for the purpose of redistribution to employees and directors. The Toronto Stock Exchange rules provide that only the creation of or certain material amendments to equity compensation plans that provide for new issuances of securities are subject to shareholder approval. The Company will follow the Toronto Stock Exchange rules with respect to the requirements for shareholder approval of equity compensation plans and material revisions to such plans.
