Solaris Resources Inc.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2024 and 2023

(Unaudited – In thousands of United States dollars, unless otherwise noted)

1. Nature of operations AND GOING CONCERN

Solaris Resources Inc. (the “Company” or “Solaris”) was incorporated under the Business Corporations Act of British Columbia on June 18, 2018 as a wholly owned subsidiary of Equinox Gold Corp. (“Equinox”). Equinox subsequently completed a spin-out of Solaris pursuant to a plan of arrangement (the “Arrangement”). Solaris’ common shares are listed on the Toronto Stock Exchange and trade under the symbol “SLS” as well as on the NYSE American LLC stock exchange under the symbol “SLSR”.

The Company is engaged in the acquisition, exploration and development of mineral property interests. The Company’s assets consist primarily of the Warintza property (“Warintza”) in Ecuador, the 60% owned La Verde property (“La Verde”) in Mexico and the Tamarugo property (“Tamarugo”) in Chile. The Company has not yet determined whether the properties contain mineral reserves where extraction is both technically feasible and commercially viable. The business of mining and exploration for minerals involves a high degree of risk and there can be no assurance that such activities will result in profitable mining operations.

These condensed consolidated interim financial statements have been prepared on a going concern basis, which assumes that the Company will be able to realize its assets and discharge its liabilities in the normal course of operations as they come due for the foreseeable future. The Company does not generate operating cash flow from a producing mine and has incurred operating losses to date. The Company has relied on cash received from share issuances and loan financing to fund its business activities, including planned corporate expenditures, exploration expenses, as well as the development activities for the Warintza project. The Company’s ability to continue as a going concern is dependent upon the successful execution of its business plan, meeting certain Warintza project milestones, raising additional capital and/or evaluating strategic alternatives for its mineral property interests. The Company expects to continue to obtain the necessary funds primarily through the remaining drawdown from the senior secured debt facility (see below) and/or the issuance of common shares in support of its business objectives. While the Company has been successful in securing financing to date, there can be no assurances that debt facilities, future equity financing, or strategic alternatives will be available on acceptable terms to the Company or at all, or that the Company will meet the conditions to receive the additional drawdown under the senior secured debt facility.

As at September 30, 2024, the Company has cash and cash equivalents of $52,509. In December 2023, the Company entered into definitive agreements with OMF Fund IV SPV D LLC and OMF Fund IV SPV E LLC, entities managed by Orion Mine Finance Management LP (collectively, “Orion”) of a financing package consisting of up to $80,000, including a $60,000 senior secured debt facility (the “Senior Loan”) of which $30,000 was received on closing, another $15,000 was received in the three months ended September 30, 2024, after the submission of an Environmental Impact Assessment (EIA), and the remaining amount to be made available upon the approval and adoption by the Company’s Board of Directors of a Pre-Feasibility Study (PFS) for the Warintza project. The Company also received in December 2023 $10,000 on issuance of common shares with an additional $10,000 of equity financing received in June 2024. Additionally, the Company successfully completed a bought deal equity financing for $29,270 in June 2024.

There are no guarantees that the Company will meet the conditions to receive the remaining drawdown of $15,000 under the Senior Loan. In addition, the Senior Loan has a financial covenant which requires the Company to maintain an unrestricted cash balance of $5,000 in Canada. Based on its current forecasted expenditures, the Company requires the additional drawdown from the Senior Loan and/or other forms of financing to fund ongoing operations for the next twelve months and to ensure it meets the covenant requirement under the Senior Loan. As a result, material uncertainty exists that may cast significant doubt about the Company’s ability to continue as a going concern. These condensed consolidated interim financial statements do not reflect the adjustments to the carrying values of assets and liabilities, the reported expenses and the condensed consolidated interim statement of financial position classifications that would be necessary if the going concern assumption was inappropriate. These adjustments could be material.

2. Basis of preparation

Statement of compliance

These condensed consolidated interim financial statements have been prepared in accordance with International Financial Accounting Standard 34 (“IAS 34”), Interim Financial Reporting, and do not include all of the information required for annual financial statements prepared in accordance with IFRS Accounting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).

However, selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in the Company’s financial position and performances since the last annual financial statements.

Solaris Resources Inc.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2024 and 2023

(Unaudited – In thousands of United States dollars, unless otherwise noted)

These condensed consolidated interim financial statements should be read in conjunction with the Company’s most recent annual audited financial statements for the year ended December 31, 2023. The accounting policies, significant judgments made by management in applying these policies and key sources of estimation uncertainty are the same as those applied in the Company’s annual audited consolidated financial statements for the year ended December 31, 2023.

These condensed consolidated interim financial statements were approved and authorized for issuance by the Board of Directors on November 12, 2024.

Amended IFRS standards effective January 1, 2024

In January 2020, the IASB issued Classification of Liabilities as Current or Non-current (Amendments to IAS 1, Presentation of Financial Statements (“IAS 1”)), which amended IAS 1 to clarify the requirements for presenting liabilities in the statement of financial position. The amendments specify that the Company must have the right to defer settlement of a liability for at least 12 months after the reporting period for the liability to be classified as non-current.

In addition, the amendments clarify that: (a) the Company’s right to defer settlement must exist at the end of the reporting period; (b) classification is unaffected by management’s intentions or expectations about whether the Company will exercise its right to defer settlement; (c) if the Company’s right to defer settlement is subject to the Company complying with specified conditions, the right exists at the end of the reporting period only if the Company complies with those conditions at the end of the reporting period, even if the lender does not test compliance until a later date; and (d) the term settlement includes the transfer of the Company’s own equity instruments to the counterparty that results in the extinguishment of the liability, except when the settlement of the liability with the Company transferring its own equity instruments is at the option of the counterparty and such option has been classified as an equity instrument, separate from the host liability.

In October 2022, the IASB issued Non-current Liabilities with Covenants, which amended IAS 1 to clarify that if the Company’s right to defer settlement of a liability for at least 12 months is subject to the Company complying with covenants after the reporting period, those covenants would not affect whether the Company’s right to defer settlement exists at the end of the reporting period for the purposes of classifying a liability as current or non-current. The amendments also increased the disclosure requirement relating to such covenants to include: (i) the nature of the covenants and the date by which the Company must comply with the covenants; (ii) whether the Company would comply with the covenants based on its circumstances at the reporting date; and (iii) whether and how the Company expects to comply with the covenants by the date on which they are contractually required to be tested.

The Company adopted the Amendments to IAS 1 effective January 1, 2024 but did not result in a change in the presentation of the Company’s liabilities. The required disclosures, where applicable, have been included in Note 6.

Certain other new standards, interpretations, and amendments to existing standards have been issued by the IASB or the International Financial Reporting Interpretations Committee. However, these updates either are not applicable to the Company or are not material to the condensed consolidated interim financial statements.

The joint venture agreement governing the operation and funding of La Verde was formalized effective February 28, 2015 (the “Agreement”). The Agreement provides that Solaris is the operator of the project. The Agreement further provides for dilution of either party’s ownership should funding not be provided in accordance with their respective participating interests. La Verde is subject to a 0.5% net smelter royalty held by Minera CIMA, S.A. de C.V.

b) Warintza

The Company owns a 100% interest in Warintza. Warintza is located in southeastern Ecuador in the province of Morona Santiago, Canton Limon Indanza.

South32 Royalty Investments Pty Ltd holds a 2% net smelter royalty on the original four concessions covering a total of 9,997 hectares.

c) ENAMI 1 Option

Solaris has entered an option agreement to acquire up to 10 new exploration concessions from the Ecuadorian state-owned mining company, Empresa Nacional Minera (“ENAMI EP”). These concessions comprise a land package of approximately 40,000 hectares adjacent to the Warintza Project and the San Carlos-Panantza porphyry copper-molybdenum deposits in southeastern Ecuador.

The Company was required to pay an upfront payment to ENAMI EP of $250 and, in order to exercise the option to acquire one or more of the 10 concessions, the Company is required to (i) incur exploration expenditures of $25,000 during the exploration phase of the concessions, as defined by the Ecuadorian Mining Law and (ii) pay the exercise price, the amount of which will be determined for each of the concessions that the Company elects to acquire by independent experts at the time of exercise. The term of the option agreement ends at the earlier of (i) the execution of the specific commercial agreement for each concession, which will stipulate a new term or (ii) four years from May 7, 2024 and is renewable with the agreement of the parties.

d) Tamarugo

Tamarugo is a grass-roots copper porphyry target strategically located in northern Chile approximately 85 kilometres northeast of Copiapo and approximately 65 kilometres southwest of Codelco’s El Salvador Copper Mine. The Company owns a 100% interest in Tamarugo, which consists of claim blocks covering a total of approximately 7,600 hectares.

e) Other projects

Solaris has earn-in agreements on certain other projects including the Capricho and Paco Orco projects in Peru. The Capricho project is a 4,200-hectare copper-molybdenum-gold property. The Paco Orco project is a 4,400-hectare lead, zinc and silver property.

Solaris Resources Inc.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2024 and 2023

(Unaudited – In thousands of United States dollars, unless otherwise noted)

The Company has the option quarterly to elect to pay the interest in cash or accruing it to the principal amount of the Senior Loan and paying it upon maturity. The interest for the three and nine months ended September 30, 2024 was accrued to the principal amount of the Senior Loan. The principal amount and all accrued and unpaid interest are due on its maturity date on December 11, 2027. The Company may prepay all or any part of the principal amount owing at any time without any premium or penalty.

Any net proceeds received by the Company from the sale of particular assets, the issuance of securities, or compensation for liquidated damages must be allocated toward repaying a portion or all of the Senior Loan, along with accrued interest. However, this repayment requirement does not apply to net proceeds raised from the issuance of securities, provided such net proceeds are: (i) used in connection with the Warintza project; or (ii) used for general corporate and administrative expenses unrelated to the Warintza project in an amount up to $2,500 annually. The Senior Loan is secured by a first-priority security ranking over the Warintza property and all the presently held and acquired undertakings, property, and assets including the equity interests in Lowell Mineral Exploration Ecuador S.A. and Lowell Copper Holdings Inc. but excluding subsidiaries and assets that are not related to the Warintza project. The Company must comply with certain covenants including maintaining a minimum unrestricted balance of $5,000 in cash in Canada. As at September 30, 2024, the Company was in compliance with all covenants.

Under the terms of the offtake agreements, OMF will purchase the greater of (i) 20% of the copper and molybdenum concentrates produced from the Warintza project in each contract year, and (ii) the percentage of production of concentrates required to deliver a minimum 30,000 tonnes of copper and 1,500 tonnes of molybdenum in each contract year as well as the corresponding amount of gold and silver contained in the copper concentrate.

The offtake agreements will expire 20 years after the achievement of commercial production as defined in the agreements. If commercial production has not been achieved by December 31, 2027, then the term will extend by one year for each calendar year that commercial production has not been achieved, and if commercial production has not been achieved by December 31, 2032, then the term is extended for the duration of the mine life as defined in the offtake agreements.

If prior to the 18-month anniversary of the Senior Loan closing date a change of control transaction (as defined in the offtake agreements) is approved by the Company’s board and announced, either party may terminate the offtake agreements prior to the end of the term which will require the Company to then pay $27,000 to OMF to terminate the copper offtake agreement and $3,000 to terminate the molybdenum offtake agreement.

11. Financial instrument risk exposure and risk management

The Company is exposed in varying degrees to a variety of financial instrument related risks. The Board of Directors approves and monitors the risk management process.

a) Credit risk

Credit risk is the risk of financial loss to the Company if a counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Company’s financial assets.

The Company is primarily exposed to credit risk on its cash and cash equivalents and amounts receivable. Credit risk exposure is limited through maintaining its cash with high-credit quality financial institutions. The carrying value of these financial assets of $53,423 represents the maximum exposure to credit risk.

b) Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company’s exposure to the risk of changes in market interest rates relates primarily to the Senior Loan which has a floating interest rate.

With all other variables held constant, a 1% change in SOFR would have changed net loss by approximately $91 and $246 for the three and nine months ended September 30, 2024, respectively (three and nine months ended September 30, 2023 – nil).

c) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company ensures that there is sufficient capital in order to meet short term business requirements after taking into account the Company’s holdings of cash.

¹ The interest is calculated using the interest rate in effect at September 30, 2024.

d) Foreign currency risk

The Company is exposed to currency risk on transactions and balances in currencies other than the functional currency. At September 30, 2024, the Company had not entered into any contracts to manage foreign exchange risk.

The functional currency of the Company is the Canadian dollar, therefore, the Company is exposed to currency risk from the assets and liabilities denominated in the US dollar. As at September 30, 2024, cash of $34,655 (December 31, 2023 – $37,245), loans and borrowings of $47,620 (December 31, 2023 – $29,363), and accounts payable and accrued liabilities of $717 (December 31, 2023 - $94) are denominated in the US dollar. For the nine months ended September 30, 2024, if the US dollar to Canadian dollar currency exchange rate changes by 5% with all other variables held constant, the impact on the Company’s net loss is $679 (nine months ended September 30, 2023 – $61).

The Company is also exposed to currency risk on financial assets and liabilities denominated in Peruvian soles, Chilean pesos, Mexican pesos and Guatemalan quetzals. However, the impact on such exposure is not currently material.

12. Fair value measurements

The carrying values of cash and cash equivalents, amounts receivable, due from related parties, restricted cash and accounts payable and accrued liabilities approximate fair value due to their short terms to maturity. The fair value of loans and borrowings is $48,307. There were no transfers between fair value levels in the periods presented.
