Notes to the Condensed Consolidated Interim Financial Statements
For the three months ended March 31, 2026 and 2025
(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 trade on the Toronto Stock Exchange under the symbol “SLS” and the NYSE American 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”) and ENAMI concessions in Ecuador, the 60% owned La Verde property (“La Verde”) in Mexico and the Tamarugo property (“Tamarugo”) in Chile. In November 2025 the results of a pre-feasibility study (“PFS”) for the Warintza Project were announced including a maiden mineral reserve estimate. The Company considers that the PFS indicates sufficient probability that costs can be recovered through future exploitation or sale. 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, loan financing and the Royal Gold funding package 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 Royal Gold funding package (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 Royal Gold funding package.
As at March 31, 2026, the Company had cash and cash equivalents of $12,894. On May 21, 2025, the Company entered into a funding package (the “Funding Package”) with RGLD Gold AG ("Royal Gold"), a subsidiary of Royal Gold, Inc. for the Warintza Project. The total cash consideration under the agreements is $200,000, comprising a gold stream agreement (the “Stream Agreement”) and net smelter return (“NSR”) royalty agreement (the “Royalty Agreement”) (collectively the “Financing Agreements”). Royal Gold will pay Solaris a total cash consideration of $200,000 in three instalments as follows:
| ● | First tranche of $100,000 upon close of the transaction (funds received at closing which occurred concurrently with signing). $90,000 allocated to the Stream Agreement (“Stream Upfront Payment”) and $10,000 allocated to the Royalty Agreement (received May 2025); |
| ● | Second tranche of $50,000 made available following the publication of the Pre-Feasibility Study (“PFS”) and receipt of the Environmental Impact Assessment technical approval (“EIA”), which will be allocated to the Stream Agreement (received April 2026, Note 19); and |
| ● | Third tranche of $50,000 made available on the first anniversary of the closing date and completion of all filings necessary to fully perfect Royal Gold’s security, which will be allocated to the Stream Agreement. |
Based on its current forecasted expenditures, the Company requires the additional financing from the third tranche of the Royal Gold funding package to fund ongoing operations for the next twelve months. As a result, material uncertainty exists that casts 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 consolidated statement of financial position classifications that would be necessary if the going concern assumption was inappropriate. These adjustments could be material. Refer to Note 8 for details on the Stream Agreement.

Notes to the Condensed Consolidated Interim Financial Statements
For the three months ended March 31, 2026 and 2025
(Unaudited – In thousands of United States dollars, unless otherwise noted)
| 2. | Basis of preparation |
| a) | Statement of compliance |
These condensed consolidated interim financial statements have been prepared in accordance with International 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 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.
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, 2025. 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, 2025.
These condensed consolidated interim financial statements were approved and authorized for issuance by the Board of Directors on May 13, 2026.
| b) | Revision of prior quarter financial statements |
In preparing the condensed consolidated interim financial statements as of and for the three and nine months ended September 30, 2025, the Company identified an error whereby a provision of $713 which had been held against salary and benefits at December 31, 2024 had not been released against the recognition of cost in the correct quarter. The identified error impacts the condensed consolidated interim financial statements for the three months ended March 31, 2025. The disclosures relating to these items in the periods mentioned above have been restated to correct for this error.
| c) | Reclassification of prior period presentation |
Certain prior period amounts have been reclassified for consistency with the current period presentation. These reclassifications had no effect on the reported results of operations or cashflows.
| (i) | Foreign exchange and other income |
For the three months ended March 31, 2025, $708 was reclassified from Interest income, other income and loan revaluation, net with $213 being presented in Interest income and $495 being presented as Foreign currency gains.

| Closing | $ | 12,480 | $ | 6,291 | ||||
| a) | La Verde |
La Verde is situated in the Sierra Madre del Sur west of Mexico City in Michoacán State, Mexico and consists of the Unificación Santa Maria claim. The project is held 60% by the Company and 40% by a subsidiary of Teck Resources Limited (“Teck”). 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 parties’ 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.
As of December 31, 2025 the lack of historical capital expenditure on the La Verde asset was identified as an indicator of impairment. Consequently, management performed an impairment test to determine the asset's recoverable amount. An independent valuation was commissioned, utilizing market and cost approaches, specifically the comparable in-situ resource multiple method. The impairment assessment determined that the asset's recoverable amount exceeded its carrying amount; therefore, no impairment loss was recognised.
| 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. It consists of nine mining concessions (the “Concessions”) covering a total of 26,773 hectares. The Concessions have a term of 25 years and can be renewed for additional periods of 25 years. South32 Royalty Investments Pty Ltd holds a 2% net smelter royalty on the original four concessions covering a total of 10,000 hectares. Additionally, Royal Gold holds a 0.3% net smelter return royalty covering a total of 18,600 hectares.
| c) | ENAMI Concessions |
| (i) | ENAMI 1 |
Solaris has entered an option agreement to acquire up to a 100% interest in 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 made an upfront payment to ENAMI EP of $250 on May 10, 2024 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.
| (ii) | ENAMI 2 |
On January 28, 2026, Solaris has entered a second option agreement with ENAMI EP to acquire up to a 100% interest in new explorations areas. The new areas expand Solaris’ footprint around Warintza by approximately 40,000 hectares and are interpreted to host significant copper mineralization, characterized by widespread potassic alteration typical of large copper porphyry systems. The award of the Solaris 2 areas follows a process established by ENAMI EP pursuant to which credentialed bidders submit nonbinding proposals for proposed minimum investments on the new areas. The award is subject to entry into a definitive framework agreement for the new areas, with the terms expected to include: (i) an upfront payment to ENAMI EP of $250; (ii) a proposed minimum exploration program of $25,000 over the 4 year exploration phase; (iii) up to $1,750 subject to the achievement of certain milestones and (iv) the exclusive option to acquire the claims from ENAMI EP at a price to be determined by independent experts. The award follows the same commercial structure as the Solaris 1 earn in arrangement.

| 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 3,769 hectare copper-molybdenum-gold property. The Paco Orco project is a 59,200 hectare lead, zinc and silver property.

| Balance, end of period | $ | 4,149 | $ | 4,227 | ||||
The reclamation provision represents the estimated costs for restoration and rehabilitation for environmental disturbances at Warintza, estimated to be incurred in the year 2027. The total undiscounted and uninflated estimated cash flows required to settle these obligations as at March 31, 2026 are $4,208 (December 31, 2025 – $4,322), which have been inflated at an average rate of 2.69% per annum (December 31, 2025 – 2.43%) and discounted at an average rate of 3.79% (December, 31, 2025 – 3.55%).
Restricted cash of $571 (December 31, 2025 – $821) represents funds being used to collateralize guarantees issued to support environmental bonding requirements with respect to the environmental disturbances at Warintza. The decrease in the year represents a guarantee put in place as part of the bidding process for the ENAMI 2 Concessions, which has subsequently been released and paid to ENAMI EP (Note 4).

| c) | Funding package with Royal Gold |
On May 21, 2025, the Company entered into a funding package with RGLD Gold AG (“Royal Gold”), a subsidiary of Royal Gold, Inc. for the Warintza Project. The total cash consideration under the Financing Agreements is $200,000, comprising a Stream Agreement and a Royalty Agreement.
Royal Gold will pay Solaris a total cash consideration of $200,000 in three instalments as follows:
First tranche of $100,000 upon close of the transaction (funds received at closing which occurred concurrently with signing). $90,000 allocated to the Stream Agreement and $10,000 allocated to the Royalty Agreement as per the contracts and cash received;
Second tranche of $50,000 made available following the publication of the PFS and receipt of the technical approval of the EIA, which will be allocated to the Stream Agreement as per the contract (see Note 19); and
Third tranche of $50,000 made available on the first anniversary of the closing date and completion of all filings necessary to fully perfect Royal Gold's security, which will be allocated to the Stream Agreement as per the contract.
Under the terms of the Stream Agreement, Royal Gold will receive gold deliveries equivalent to 20 ounces per 1 million pounds of copper produced from a defined area (RGLD Gold AOI). For each ounce of gold delivered under the Stream Agreement, Royal Gold will pay the Company a purchase price equal to 20% of spot price until 90,000 ounces have been delivered; and then 60% of spot price thereafter.
Under the terms of the Royalty Agreement, Royal Gold will receive a 0.3% net smelter return royalty on all metal production from a defined area (RGLD Gold Expanded AOI). The Royalty will increase annually by 0.0375%, up to a maximum of 0.6%, until the earlier of: the first delivery of gold under the Stream Agreement; or eight years following the closing date.

The Company’s obligations under the Stream Agreement and related documents are secured by (i) an all-asset British Columbia-law general security agreement made by the Company in favour of Royal Gold, and (ii) a British Columbia law share pledge agreement made by the Company in favour of Royal Gold in respect of all of the shares of its direct wholly owned subsidiary Lowell Copper Holdings Inc. (“Lowell Copper”). The obligations under the Stream Agreement are further guaranteed pursuant to a British Columbia-law guarantee from (i) Lowell Copper, which guaranteed obligations are secured by an all-asset British Columbia-law general security agreement made by Lowell Copper in favour of Royal Gold, and (ii) Lowell Mineral Exploration Ecuador S.A. (“Lowell Ecuador”). The obligations under the Stream Agreement will be further (i) secured pursuant to an Ecuador-law share pledge agreement to be granted by Lowell Copper in favour of Royal Gold in respect of all of the shares of its direct wholly-owned subsidiary Lowell Ecuador, and (ii) guaranteed pursuant to an Ecuador-law guarantee to be granted by Lowell Ecuador in favour of Royal Gold, which guaranteed obligations are to be secured by an Ecuador-law assignment of mining rights.
Solaris Resources AG’s (“Solaris Switzerland”) obligations under the Royalty Agreement and related documents are guaranteed (i) by a British Columbia-law limited recourse guarantee from the Company, which guaranteed obligations are to be secured by a Swiss-law share pledge agreement to be granted by the Company in respect of all of the shares of its direct wholly-owned subsidiary Solaris Switzerland. In addition to the above-noted guarantees and security, as further guarantees and security for the obligations under the Royalty Agreement, (i) Solaris Switzerland is to grant in favour of Royal Gold a Swiss-law security assignment of all receivables owed by the Company or Lowell Ecuador to Solaris Switzerland in respect of certain intercompany receivables and funding arrangements between the Company or Lowell Ecuador and Solaris Switzerland, (ii) the Company is to grant in favour of Royal Gold a Swiss-law share pledge agreement in respect of all of the shares of its direct wholly-owned subsidiary Solaris Switzerland. Additionally, the guarantees and security granted to Royal Gold in respect of the obligations under the Stream Agreement are to guarantee and/or secure the obligations under the Royalty Agreement.
The Company recorded the Stream Upfront Payment as deferred revenue. The Company determines the amortization of deferred revenue on a per unit basis using the estimated total gold production over the life of the Warintza Project.
Deferred revenue consists of: 1) initial Stream Upfront Payment received by the Company for future delivery of gold under the terms of the Stream Agreement, and 2) a significant financing component of the Stream Agreement resulting from the difference in the timing of the upfront payment received and the promised goods delivered. As such, the Company recognizes interest expense at each reporting period and will accrete the deferred revenue balance to recognize the significant financing element that is part of the Stream Agreement. The interest rate of 4.6% is determined based on the effective rate in the expected deliveries against the deferred revenue.

| 14. | 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 prepaids and other 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 $13,598 represents the maximum exposure to credit risk.
| b) | 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.
At March 31, 2026, the Company had contractual undiscounted cash flow commitments as follows:
| < 1 Year | 1-3 Years | 4-5 Years | > 5 Years | Total | ||||||||||||||||
| Accounts payable and accrued liabilities | $ | 3,596 | $ | – | $ | – | $ | – | $ | 3,596 | ||||||||||
| Lease liabilities | 200 | 296 | – | – | 496 | |||||||||||||||
| Other long-term liabilities | – | – | – | 316 | 316 | |||||||||||||||
| Exploration and evaluation assets | 770 | 378 | – | – | 1,148 | |||||||||||||||
| $ | 4,566 | $ | 674 | $ | – | $ | 316 | $ | 5,556 | |||||||||||
| c) | Foreign currency risk |
The Company is exposed to currency risk on transactions and balances in currencies other than the functional currency. At March 31, 2026, 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 March 31, 2026, cash of $ 8,234 (December 31, 2025 – $19,257), and accounts payable and accrued liabilities of $340 (December 31, 2025 - $88) are denominated in the US dollar. For the three months ended March 31, 2026, 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 would be $411 (three months ended March 31, 2025 – $943).
The Company is also exposed to currency risk on financial assets and liabilities denominated in a range of currencies. However, the impact on such exposure is not currently material.

These services have been provided through a management company equally owned by each company party to the arrangement. Costs incurred by the management company are allocated and funded by the shareholders of the management company based on time incurred and use of services.

The approval represents a major permitting milestone and a significant de-risking event of the project following an extensive technical review process conducted by a multidisciplinary team from the Ministry of Environment and Energy.
Following the publication of the PFS in November 2025 and the receipt of the EIA technical approval, Solaris satisfied the conditions required to draw down the second tranche under its $200,000 financing agreement with Royal Gold and the Company received the additional $50,000 funding on April 14, 2026.
