(the “Company”) is a Canadian issuer eligible to file this 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.

Any such forward-looking statements are based, in part, on assumptions and factors that may change, thus causing actual results or achievements to differ materially from those expressed or implied by the forward-looking statements. Such factors and assumptions may include, but are not limited to: assumptions concerning copper, gold and other base and precious metal prices; cut-off grades; accuracy of mineral resource estimates and resource modeling; timing and reliability of sampling and assay data; representativeness of mineralization; timing and accuracy of metallurgical test work; anticipated political and social conditions; expected government policy, including reforms; ability to successfully raise additional capital; assumptions regarding obtaining required approvals; assumptions regarding Solaris’ ability to satisfy the conditions precedent to the advancement of the remaining amount under the Funding Package; and other assumptions used as a basis for preparation of the Technical Report (as defined below).

Such risks and other factors include, among others, and without limitation: the ability to raise funding to continue exploration, development and mining activities; Funding Package; financing arrangements; global economic conditions; limited supplies, supply chain disruptions and inflation; negative operating cash flow; uncertainty of future revenues or of a return on investment; estimation risk in mineral resources and mineral reserves; uncertainty relating to inferred mineral resources; speculative nature of mineral exploration and development; risks from international operations; risks associated with an emerging and developing market; relationships with, and claims by, local communities and Indigenous Groups; geopolitical risk; risks related to obtaining future environmental licenses for exploitation; permitting risk; Ecuadorian constitutional court rulings suspending licenses; anti-mining sentiment; failure to comply strictly with applicable laws, regulations and local practices; pressure from artisanal and illegal miners; risks associated with mining, exploration and development; land title risk; surface rights and access risks; changes in laws and policies regulating international trade; international conflicts; global outbreaks and contagious diseases; fraud and corruption; ethics and business practices; future legal proceedings; tax regime in Ecuador; mineral assets being located outside Canada and held indirectly through foreign affiliates; commodity price risk; exchange rate fluctuations; joint ventures; property commitments; infrastructure; water management; properties located in remote areas; lack of availability of resources; dependence on highly skilled personnel; competition; significant shareholders; reputational risk; conflicts of interest; uninsurable risks; information systems; artificial intelligence, public company obligations; reliability of financial reporting and financial statement preparation; foreign subsidiary operations may impact the Company’s ability to fund operations efficiently; price fluctuation of the Company’s common shares (the “Common Shares”); value of the Common Shares; future sales of Common Shares by existing shareholders; costs of land reclamation; measures to protect endangered species; environmental risks and hazards and changes in climate conditions; differences in U.S. and Canadian reporting of mineral reserves and resources; the Company’s “foreign private issuer” status; claims under U.S. securities laws, as well as those factors discussed in ITEM 7: “Risk Factors” in the Company’s Annual Information Form (“AIF”) for the fiscal year ended December 31, 2025, filed with this annual report on Form 40-F as Exhibit 99.1.

Although the Company has attempted to identify important factors and risks that could affect the Company and might cause actual actions, events or results to differ, perhaps materially, from those described in forward-looking statements, there may be other factors and risks not identified herein that cause actions, events or results not to occur as projected, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The forward-looking statements in this annual report and the documents incorporated herein by reference speak only as of the date hereof. The Company does not undertake any obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events, except as required by law.

MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

The Company’s AIF filed as Exhibit 99.1 to this annual report on Form 40-F and Management’s Discussion and Analysis for the fiscal year ended December 31, 2025 filed as Exhibit 99.3 have been prepared in accordance with the requirements of Canadian provincial securities laws, which differ from the requirements of United States securities laws.

As a result, the Company reports the mineral reserves and resources of the projects it has an interest in according to Canadian standards. Canadian reporting requirements for disclosure of mineral properties are governed by 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 from the requirements of the SEC that are applicable to domestic United States reporting companies under subpart 1300 of Regulation S-K (“SK 1300”) under the Exchange Act. As an issuer that prepares and files its reports with the SEC pursuant to the multijurisdictional disclosure system, the Company is not subject to the requirements of sub part1300 of Regulation S-K. Any mineral reserves and mineral resources reported by the Company in accordance with NI 43 101 may not qualify as such under or differ from those prepared in accordance with SK 1300. Accordingly, information included or incorporated by reference in the Company’s AIF filed as Exhibit 99.1 to this annual report on Form 40-F and management’s discussion and analysis for the fiscal year ended December 31, 2025 filed as Exhibit 99.3 concerning descriptions of mineralization and estimates of mineral reserves and resources under Canadian standards may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of SK 1300.

DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted, under a multi-jurisdictional disclosure system adopted by the United States and Canada, to prepare this annual report on Form 40-F in accordance with Canadian disclosure requirements, which are different from those of the United States. The Company prepares its financial statements, which are filed with this annual report Form 40-F, in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IFRS”), and the audit is subject to the standards of the Public Company Accounting Oversight Board (United States). Such financial statements may not be comparable to financial statements of United States companies prepared in accordance with United States generally accepted accounting principles.

CURRENCY

Unless otherwise indicated, all dollar amounts in this annual report on Form 40-F are in United States dollars. The exchange rate of Canadian dollars into United States dollars, on December 31, 2025, based upon the closing exchange rate as quoted by the Bank of Canada, was U.S.$1.00 = CAD$ 1.3706 (CAD$1.00 = U.S.$ 0.7296).

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

At the end of the period covered by this annual report on Form 40-F for the fiscal year ended December 31, 2025, an evaluation was carried out under the supervision of, and with the participation of, the Company’s management, including its Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based upon that evaluation, the Company’s CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective to give reasonable assurance that the 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 the SEC’s rules and forms, and (ii) accumulated and communicated to management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) of the Exchange Act. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. It should be noted that a control system, no matter how well conceived or operated, can only provide reasonable assurance, not absolute assurance, that the objectives of the control system are met.

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 policies and procedures may deteriorate.

Management, including the CEO and CFO, assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria set forth in the Internal Control Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment, and given the identified material weakness as described below management concluded that the Company’s internal control over financial reporting was not effective as of December 31, 2025.

Material Weakness

For the year ended December 31, 2025, we identified a material weakness in our internal control over financial reporting. A material weakness is defined as a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

We did not appropriately design and implement certain controls at a sufficient level of precision within our financial statement close process and related disclosures including: (i) recording of payroll expenses in general and administrative expenses, (ii) foreign currency calculations related to retranslation of deferred revenue to the functional currency and amortization of loan arrangement fees, (iii) disclosure and presentation of capital expenditure on exploration and evaluation assets within the consolidated statement of cash flows, and (iv) calculation of the tax provision. These control deficiencies resulted in errors that were corrected by management.

Remediation Plan

To address the material weakness the Company has taken the following actions:

	●	Management has reviewed the controls relating to financial close procedures, to ensure increased oversight.

	●	A new accounting system has been implemented.

●

An additional senior team member has been recruited to the finance team, as of September 1, 2025, to provide additional resources and oversight within the internal accounting and financial reporting areas.

Although this material weakness did not result in any material misstatement of our consolidated financial statements for the periods presented, it could lead to a material misstatement of account balances or disclosures. Accordingly, management has concluded that these control deficiencies constitute a material weakness. With respect to the material weakness above, management, under the oversight of the Audit Committee, is taking steps to address the issue. While we implement our remediation plan, the material weakness will not be considered remediated until the enhanced controls operate for a sufficient period of time and management has concluded, through testing, that the related controls are effective. The Company will monitor the effectiveness of its remediation plan and refine its remediation plan as appropriate.

Auditor’s Attestation Report

This annual report does not include an attestation report of the Company’s independent registered public accounting firm because the Company qualifies as an “emerging growth company” and is exempt from the requirement to provide the attestation report.

Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting that occurred during the fiscal year ended December 31, 2025 that have materially affected, or are reasonably likely to materially 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 LLC (“NYSE American”) and additionally complies as necessary with the rules and guidelines of the NYSE American as well as the SEC.

The Company’s Board of Directors is responsible for the Company’s Corporate Governance policies and has separately designated standing Audit, Compensation and Nominating & Corporate Governance Committees. The Company’s Board of Directors has determined that all the members of the Audit, Compensation, and Nominating & Corporate Governance Committees are independent, based on the criteria for independence and unrelatedness prescribed by the TSX and Section 803A of the NYSE American Company Guide. The Board holds meetings on at least a quarterly basis and the independent directors meet on a regular basis as often as necessary to fulfill their responsibilities, including at least annually in executive session without the presence of non-independent directors and management pursuant to Section 802(c) of the NYSE American Company Guide.

Compensation Committee

Compensation of the Company’s CEO and all other officers is recommended to the Board of Directors for determination by the Compensation Committee. The Compensation Committee develops, reviews and monitors director and executive officer compensation and policies. The Compensation Committee is also responsible for annually reviewing the adequacy of compensation to directors, officers, and other consultants and the composition of compensation packages. The Company’s CEO cannot be present during the Compensation Committee’s deliberations or vote on the CEO’s compensation.

The Compensation Committee is composed of Donald Taylor and Rodrigo Borja, each of whom, in the opinion of the Board of Directors, is independent under the rules of the TSX and pursuant to Sections 803A and 805(c)(1) of the NYSE American Company Guide. The Company’s Compensation Committee Charter is available on the Company’s website at www.solarisresources.com.

Nominating & Corporate Governance Committee

Nominees for the election to the Company’s Board of Directors are recommended by the Nominating & Corporate Governance Committee. The Company has adopted a formal written board resolution addressing the nomination process and such related matters as may be required under the rules of the TSX and the NYSE American and any applicable securities laws.

The Nominating & Corporate Governance Committee is composed of Rodrigo Borja and Hans Wick, each of whom, in the opinion of the Board of Directors, is independent under the rules of the TSX and the NYSE American. The Company’s Nominating and Corporate Governance Committee Charter is available on the Company’s website at www.solarisresources.com.

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 the Company’s year ended December 31, 2025, the Company’s Audit Committee is composed of Donald Taylor, Hans Wick and Rodrigo Borja, each of whom, in the opinion of the Company’s Board of Directors, is independent (as determined under Rule 10A-3 of the Exchange Act, Section 803A of the NYSE American Company Guide, and the rules of the TSX) 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.

Donald Taylor has over 30 years of domestic and international mining executive experience taking projects from exploration to mining. He is currently the Chief Executive Officer of Titan Metals Corporation. Donald has worked extensively for large and small cap companies, including Arizona Mining, BHP Minerals, Bear Creek Mining, American Copper and Nickel, Doe Run Resources, Westmont Mining Company, Titan Mining, and Augusta Gold Corp.

Hans Wick has decades of experience in the financial services and investment sector, with his most recent role as the Managing Director of a Swiss private bank. As a senior financial services and investment professional, Hans benefits from an in-depth knowledge of the sector and a wide network of contacts which he applies to his mandates and lends to the boards of directors he serves on. Over the course of his banking career, Hans has also been active in the mining sector for decades as an investor and advisor to numerous companies.

Rodrigo Borja is a senior lawyer with decades of experience in Ecuador, including as the Chief Legal Officer (“CLO”) of several foreign companies with operations in the mining and oil sectors. In the mining sector, Rodrigo was CLO of Kinross’ Ecuador subsidiary, where he managed all legal aspects of the company. He led the negotiations with the Ecuadorian state for the Mining Exploitation Contract for the Fruta del Norte project and the investment contract that protects foreign investment. Rodrigo is currently a partner with AVL Abogados where he leads its mining practice. Prior to this, Rodrigo was the CLO of the Brazilian oil company Petrobras, responsible for all legal aspects of its operation from 2002 to 2010. He was also a member of the Executive Committee, as well as an alternate member of the board of directors of OCP Ecuador, Ecuador’s main oil pipeline.

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

The Audit Committee meets with the Company’s CEO, President and 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 fiscal 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 AIF, filed as Exhibit 99.1 to this annual report on Form 40-F and incorporated by reference herein.

Audit Committee Financial Expert

CODE OF ETHICS

The Company has adopted a Code of Business Conduct and Ethics (the “Code”) that applies to all the Company’s directors, executive officers and employees, which is available on the Company’s website at www.solarisresources.com and in print to any shareholder who requests it. The Code meets the requirements for a “code of ethics” within the meaning of that term in General Instruction 9(b) of Form 40-F.

All amendments to the Code, and all waivers of the Code with respect to any of the officers covered by it, will be posted on the Company’s website, www.solarisresources.com within five business days of the amendment or waiver and will remain available for a twelve-month period and provided in print to any shareholder who requests them.

NYSE AMERICAN CORPORATE GOVERNANCE

A foreign private issuer that follows home country practices in lieu of certain provisions of the listing rules of the NYSE American must disclose the ways in which its corporate governance practices differ from those followed by U.S. domestic companies. As required by Section 110 of the NYSE American Company Guide, the Company discloses on its website, www.solarisresources.com, a description of the significant ways in which the Company’s corporate governance practices differ from those followed by United States domestic companies pursuant to NYSE American standards.

A description of the significant ways in which the governance practices of the Company differ from those followed by domestic companies pursuant to NYSE American standards is as follows:

Proxy Solicitations Under Section 705, listed companies must comply with applicable state and federal laws and rules (including interpretations thereof), including without limitation, Exchange Act Regulations 14A and 14C. The Company is a “foreign private issuer” as defined in Rule 3b-4 under the Exchange Act, and the equity securities of the Company are accordingly exempt from the proxy rules set forth in Sections 14(a), 14(b), 14(c) and 14(f) of the Exchange Act. The Company solicits proxies in accordance with applicable rules and regulations in Canada.

Quorum Requirements Under Section 123, the NYSE American expects that an appropriate quorum of the shares issued and outstanding and entitled to vote will be provided for by the by-laws of companies listing voting securities. The NYSE American recommends a quorum of at least 33 1/3%. The Company is subject to the Business Corporations Act (British Columbia), which permits the Company to specify a quorum requirement in its memorandum or articles. Under the Company’s articles, quorum for the transaction of business at any meeting of shareholders is at least one shareholder represented in person or by proxy.

Shareholder Approval Requirements Sections 711-713 require that a listed company obtain shareholder approval for: (i) the establishment or material amendment of a plan or other equity compensation arrangement, subject to exceptions; (ii) the issuance of shares as sole or partial consideration for an acquisition of the stock or assets of another company in certain circumstances; and (iii) certain transactions other than public offerings that may result in the issuance of common shares (or securities convertible into common shares) equal to 20% or more of presently outstanding shares for less than the greater of book or market value of the shares. Neither Canadian securities laws nor Canadian corporate law require shareholder approval for such transactions, except where such transactions constitute a “related party transaction” or a “business combination” under Canadian securities laws or where such transaction is structured in a way that requires shareholder approval under the Business Corporations Act (British Columbia), or where the Toronto Stock Exchange requires shareholder approval for a transaction involving a change of control of the Company, or the establishment of or amendments to equity-based compensation plans, in which case, the Company intends to follow its home country requirements. 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 our home country law, in which case, the Company shall make the disclosure of such transactions available on its website at www.solarisresources.com.

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 (the “Mine Act”). During the fiscal year ended December 31, 2025, the Company had no mines in the United States subject to regulation by MSHA under the Mine Act.

RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION

The Company has adopted a compensation recovery policy (referred to as the “Incentive Compensation Clawback Policy”) as required by NYSE American listing standards and pursuant to Rule 10D-1 of the Exchange Act. The Incentive Compensation Clawback Policy is incorporated by reference to Exhibit 97 to this annual report on Form 40-F. At no time during or after the fiscal year ended December 31, 2025 (as of the date of this annual report), was the Company required to prepare an accounting restatement that required recovery of erroneously awarded compensation pursuant to the Incentive Compensation Clawback Policy and, as of December 31, 2025, there was no outstanding balance of erroneously awarded compensation to be recovered from the application of the Incentive Compensation Clawback Policy to a prior restatement.

DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS
