EXPLANATORY NOTE

Skeena Resources Limited (the “Company” or the “Registrant”) is a British Columbia corporation that is permitted, under the multijurisdictional disclosure system adopted in the United States, to prepare this Annual Report on Form 40-F (this “Annual Report”) pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in accordance with Canadian disclosure requirements, which are different from those of the United States. The Company is a “foreign private issuer” as defined in Rule 3b-4 under the Exchange Act and Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”). Equity securities of the Company are accordingly exempt from Sections 14(a), 14(b), 14(c), 14(f) and 16 (b) and (c) of the Exchange Act pursuant to Rule 3a12-3 thereunder.

PRINCIPAL DOCUMENTS

The following documents, filed as Exhibits 99.1, 99.2 and 99.3 hereto, are incorporated herein by reference into this Annual Report:

A.	Annual Information Form of the Company for the year ended December 31, 2025 (the “AIF”).

B.	Management’s Discussion and Analysis of the Company for the year ended December 31, 2025 (the “MD&A”).

C.	Audited Consolidated Financial Statements of the Company for the year ended December 31, 2025 (the “Audited Financial Statements”).

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this Annual Report and the exhibits attached hereto are forward-looking statements under the provisions of the United States Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act, Section 21E of the Exchange Act and forward-looking information within the meaning of applicable Canadian securities legislation (collectively, “forward-looking statements”). Forward-looking statements are subject to risks, uncertainties and contingencies that could cause actual results to differ materially from those expressed or implied by these forward-looking statements. Investors are cautioned not to put undue reliance on forward-looking statements. Applicable risks and uncertainties include, but are not limited to, those identified under the heading “Risk Factors” in the AIF and MD&A and in other filings that the Company has made and may make with applicable securities regulatory authorities in the future. Please also see the section “Forward-Looking Statements” in the AIF and MD&A for a discussion of forward-looking statements. Except as required by applicable law, the Company does not intend, and undertakes no obligation, to update any forward-looking statements to reflect, in particular, new information or future events, or otherwise.

MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

The disclosure included in or incorporated by reference in this Annual Report uses mineral reserves and mineral resources classification terms that comply with reporting standards in Canada and are made in accordance with National Instrument 43-101—Standards of Disclosure for Mineral Projects (“NI 43-101”). 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.

These standards differ significantly from the requirements of the Securities and Exchange Commission (the “Commission” or the “SEC”) that are applicable to domestic United States reporting companies. Any mineral reserves and mineral resources reported by the Company in accordance with NI 43-101 may not qualify as such under SEC standards. Accordingly, information included in this Annual Report and the documents incorporated by reference herein that describes the Company’s mineral reserves and mineral resources estimates may not be comparable with information made public by United States companies subject to the SEC’s reporting and disclosure requirements.

DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted, under a multijurisdictional disclosure system adopted by the United States, to prepare this report in accordance with Canadian disclosure requirements, which are different from those of the United States. The Company prepares its consolidated financial statements, which are filed with this Annual Report, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and which are not comparable to financial statements of United States companies.

CURRENCY

Unless otherwise indicated, all references to “$”, “C$” or “dollars” in this Annual Report refer to Canadian dollars. References to “US$” in this Annual Report refer to United States dollars. The exchange rate of Canadian dollars into United States dollars on December 31, 2024, based upon the daily average exchange rate as quoted by the Bank of Canada, was C$1.00 = US$0.6950. The exchange rate of Canadian dollars into United States dollars, on December 31, 2025, based upon the daily average exchange rate as quoted by the Bank of Canada, was C$1.00 = US$0.7296.

DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING

A.Evaluation of disclosure controls and procedures. Disclosure controls and procedures are designed to ensure that (i) 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 (ii) material information required to be disclosed in the Company’s reports filed under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer (“CEO”) and its Chief Financial Officer (“CFO”), as appropriate, to allow for timely decisions regarding required disclosure.

At the end of the period covered by this report, an evaluation was carried out under the supervision of and with the participation of the Company’s management, including the CEO and CFO, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act). The evaluation included documentation review, enquiries and other procedures considered by management to be appropriate in the circumstances. Based on that evaluation, the Company’s CEO and CFO have concluded that, as of December 31, 2025, the Company’s disclosure controls and procedures were effective.

B.Management’s annual report on internal control over financial reporting. Management of the Company, under the supervision of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over the Company’s financial reporting. Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We, including the CEO and CFO, have assessed the effectiveness of the Company’s internal control over financial reporting in accordance with the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, we, including the CEO and CFO, have determined that the Company’s internal control over financial reporting was effective as at December 31, 2025. See “Internal Control over Financial Reporting” in the MD&A.

C.Attestation report of the registered public accounting firm. The effectiveness of the Company’s internal control over financial reporting as at December 31, 2025 has been audited by KPMG LLP (PCAOB ID No. 85), an independent registered public accounting firm, as stated in their report, issued in Vancouver, British Columbia, Canada, which accompanies our Audited Financial Statements, and is incorporated herein by reference.

D.Changes in internal control over financial reporting. During the period covered by this Annual Report, no change occurred in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. See “Internal Control over Financial Reporting” in the MD&A.

The Company’s management, including the CEO and CFO, does not expect that its disclosure controls and procedures or internal controls and procedures will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

NOTICES PURSUANT TO REGULATION BTR

The Company was not required by Rule 104 of Regulation BTR to send any notices to any of its directors or executive officers during the fiscal year ended December 31, 2025.

AUDIT COMMITTEE FINANCIAL EXPERT

The Company’s board of directors (the “Board”) has determined that it has at least one audit committee financial expert serving on its audit committee. The Board has determined that Suki Gill is an audit committee financial expert and is independent, as that term is defined by the Exchange Act and the New York Stock Exchange’s (“NYSE”) corporate governance standards applicable to the Company.

The Commission has indicated that the designation of a person as an audit committee financial expert does not make such person an “expert” for any purpose, impose on such person any duties, obligations or liability that are greater than those imposed on such person as a member of the audit committee and the Board in the absence of such designation and does not affect the duties, obligations or liability of any other member of the audit committee or Board.

CODE OF ETHICS

The Board has adopted a written code of business conduct and ethics (the “Code”), by which it and all officers and employees of the Company, including the Company’s principal executive officer, principal financial officer and principal accounting officer or controller, abide. There were no waivers granted in respect of the Code during the fiscal year ended December 31, 2025. The Code is posted on the Company’s website at www.skeenaresources.com. If there is an amendment to the Code, or if a waiver of the Code is granted to any of Company’s principal executive officer, principal financial officer, principal accounting officer or controller, the Company intends to disclose any such amendment or waiver by posting such information on the Company’s website. Unless and to the extent specifically referred to herein, the information on the Company’s website shall not be deemed to be incorporated by reference in this Annual Report. Except for the Code, and notwithstanding any reference to the Company’s website or other websites in this Annual Report or in the documents incorporated by reference herein or attached as Exhibits hereto, no information contained on the Company’s website or any other site shall be incorporated by reference in this Annual Report or in the documents incorporated by reference herein or attached as Exhibits hereto.

PRINCIPAL ACCOUNTANT FEES AND SERVICES

Our independent registered public accounting firm is KPMG LLP, Vancouver, B.C., Canada, Auditor Firm ID: 85. See the section “External Auditor Service Fees” in our AIF, which section is incorporated by reference herein, for the total amount billed to the Company by KPMG LLP for services performed in the last two fiscal years by category of service (for audit fees, audit-related fees, tax fees and all other fees).

AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES

See the section “Pre-Approval Policies and Procedures” in our AIF, which section is incorporated by reference herein. One hundred percent of the audit-related fees, tax fees and all other fees billed to the Company by KPMG LLP were approved by the Company’s audit committee.

IDENTIFICATION OF THE AUDIT COMMITTEE

The Board has a separately designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act and satisfies the requirements of Exchange Act Rule 10A-3. As at December 31, 2025, the audit committee was comprised of Suki Gill, Greg Beard, and Hansjoerg Plaggemars, all of whom, in the opinion of the Company’s Board, are independent (as determined under Rule 10A-3 of the Exchange Act and the rules of the NYSE) and are financially literate.

CORPORATE GOVERNANCE PRACTICES

The NYSE Listed Company Manual generally requires that a listed company’s by-laws provide for a quorum for any meeting of the holders of the company’s common shares that is sufficiently high to ensure a representative vote. As a foreign private issuer, we have elected to comply with practices that are permitted under Canadian law in lieu of this NYSE requirement. Our by-laws provide that a quorum for the transaction of business at any meeting of shareholders shall be at least one person who is, or who represents by proxy, one or more shareholders who, in the aggregate, hold at least 5% of the issued shares entitled to be voted at the meeting.

Except as stated above, we are in compliance with the rules generally applicable to U.S. domestic companies listed on the NYSE. We may in the future decide to use other foreign private issuer exemptions with respect to some of the other NYSE listing requirements. Following our home country governance practices, as opposed to the requirements that would otherwise apply to a company listed on the NYSE, may provide less or different protection than is accorded to investors under the NYSE listing requirements applicable to U.S. domestic issuers.

MINE SAFETY DISCLOSURE

Not applicable.

DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS

Not applicable.
