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

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

2. Basis of preparation

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;c) ENAMI Concessions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

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).

At May 21, 2025 when fully repaid, the Senior Loan Facility was measured at amortized cost using an effective interest rate of 16.18%.

The Company had the option quarterly to elect to pay the interest in cash or accruing it to the principal amount of the Senior Loan Facility and paying it upon maturity. The interest until repayment was accrued to the principal amount of the Senior Loan Facility.

&nbsp;&nbsp;&nbsp;&nbsp;b) Offtake agreements

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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

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

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.

&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;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 | $3596 | $– | $– | $– | $3596 |
| Lease liabilities | 200 | 296 |  |  | 496 |
| Other long-term liabilities |  |  |  | 316 | 316 |
| Exploration and evaluation assets | 770 | 378 | – | – | 1148 |
|  | $4566 | $674 | $– | $316 | $5556 |

---

&nbsp;&nbsp;&nbsp;&nbsp;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.

**Cautionary Note Regarding Presentation of Mineral Reserve and Mineral Resource Estimates**

This MD&A was prepared in accordance with Canadian standards for reporting of mineral resource estimates, which differ from United States standards. In particular, and without limiting the generality of the foregoing, the technical and scientific information contained and incorporated by reference in this MD&A was prepared in accordance with 43-101 – *Standards of Disclosure for Mineral Projects* ("NI 43-101") under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum Standards for Mineral Resources and Mineral Reserves, Definitions and Guidelines (the "CIM Standards"), which differs from the standards adopted by the U.S. Securities and Exchange Commission (the "SEC") under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). Accordingly, estimates of the Company's Mineral Reserves and Mineral Resources, and other technical and scientific information included or incorporated by reference in this MD&A, may differ materially from the information that would be disclosed by a United States company subject to the SEC standards under the Exchange Act.

**Description of Business**

Solaris Resources is a copper-gold exploration and development company advancing a portfolio of high-quality assets across the Americas. Its flagship asset is the 100%-owned Warintza copper porphyry Project in southeast Ecuador. Solaris is committed to responsible mining practices that prioritize environmental stewardship, shared value creation, and long-term benefits for local communities and stakeholders.

**Highlights and Activities**

The following activities and developments were achieved during the quarter:

● Solaris announced a major advancement in its district-scale growth strategy on January 28, 2026. Ecuador's state-owned mining company, Empresa Nacional Minera ENAMI EP ("ENAMI EP") granted Solaris an option to acquire up to a 100% interest in a new portfolio of highly prospective exploration areas located immediately adjacent to the Company's world-class Warintza Project in southeastern Ecuador. This strategic award meaningfully expands Solaris' footprint around Warintza by approximately 40,000 hectares, further consolidating its presence over one of the most compelling emerging copper districts globally. The newly optioned areas capture extensions of key geological trends continuous with Warintza, unlocking additional potential exploration upside and reinforcing the Company's long-term vision of developing a future world-class copper mining hub.

Subsequent to quarter-end:

● On April 9, 2026, Solaris announced that it had received the technical approval of the EIA for its Warintza Project. The approval represents a major permitting milestone and a significant de-risking event for the project following an extensive technical review process conducted by a multidisciplinary team from the Ministry of Environment and Energy. Following receipt of the EIA technical approval, the Warintza Project will advance through the remaining stages of Ecuador's environmental licensing and development approval process including the Government-led FPIC process. Following the publication of the Pre-Feasibility Study in November 2025 and the receipt of EIA technical approval, Solaris has satisfied the conditions required to draw down the second tranche under its US$200 million financing agreement with Royal Gold, which closed in May 2025. This milestone enables the Company to access US$50 million in additional funding, which was received in April 2026, that further strengthens the Company's balance sheet and provides additional financial flexibility to advance key development activities at Warintza.

**<u>OUTLOOK</u>**

Following the receipt of the Technical Approval of the EIA in April 2026, Solaris will advance through the remaining stages of Ecuador's environmental licensing and development approval process including the Government-led FPIC process.

Solaris will continue to advance the Feasibility Study for Warintza, having engaged globally recognized engineering and technical firms including Ausenco, Knight Piésold and AMC Consultants, who successfully delivered the Project's Pre-Feasibility Study ("PFS") published in November 2025. The Feasibility Study is focused on optimizing mine design and infrastructure, refining tailings management solutions, advancing capital and operating cost estimates, and establishing a clear pathway toward an informed construction decision.

Solaris is simultaneously performing work to unlock value across its broader 100%-owned land package of over 260 km², which contains several high-priority regional targets.

Solaris remains committed to its participatory mining model, fostering strong local partnerships and social license while building long-term value for all stakeholders.

**Warintza** 

Warintza is a large-scale porphyry copper-molybdenum-gold project located in southeastern Ecuador in the province of Morona Santiago, Canton Limon Indanza, north of the Mirador copper-gold mine (owned by CRCC-Tongguan) and the Fruta del Norte gold mine (owned by Lundin Gold) and adjacent to the San Carlos-Panantza copper project (owned by CRCC-Tongguan) ("Warintza", the "Project" or the "Warintza Project").

The property includes nine metallic mineral concessions covering 26,773 hectares. Four concessions with an area of 9,997 hectares are permitted for exploration activities including drilling and path construction. South32 Royalty Investments Pty Ltd holds a 2% net smelter royalty on the original four concessions. Concessions have a term of 25 years and can be renewed for additional periods of 25 years. In April 2024, the Company announced an option to acquire up to a 100% interest in 10 new explorations concessions, comprising a land package of ~40,000 hectares adjacent to Warintza and interpreted to host porphyry copper and epithermal gold potential. Further, in January 2026, the Company also announced a second option to acquire up to a 100% interest in new exploration areas located immediately adjacent to the Warintza Project. These new areas are interpreted to host significant copper mineralization, characterized by widespread potassic alteration typical of large copper porphyry systems.

Warintza enjoys the support of its local Shuar Centres of Warints and Yawi with whom the Company shares an Impact and Benefit Agreement ("IBA"), which was first signed in September 2020, renewed in March 2022 and again renewed in April 2024. The IBA provides certainty of community support for the responsible advancement of the Warintza Project from exploration and development through to production and is a major milestone in the Company's innovative corporate social responsibility program. This was the first IBA established in Ecuador and set the precedent for industry best practice for inclusive and mutually beneficial resource development in partnership with Indigenous Peoples. The IBA formalizes commitments toward supporting partner communities in their social and cultural practices. It also provides for eliminating or mitigating adverse impacts, employment, contracting and business opportunities supported by a robust program of education, skills and training together with community infrastructure development and financial benefits to maximize community participation and positive outcomes for Indigenous Peoples. In March 2024, Solaris announced a trilateral cooperation agreement with FICSH, the highest authority and largest Shuar indigenous organization legally established by statute of the Ministry of Social Welfare of Ecuador in 1964 and includes 50 associations comprising 500 Shuar communities and approximately 143,000 Shuar indigenous people, and with the Alianza para el Emprendimiento e Innovación ("AEI") of Ecuador. The agreement aims to promote the economic and social development of Shuar communities represented by FICSH, including the communities of Warints and Yawi, with programs in health, education, skills training, entrepreneurship, innovation and sustainable mineral resource development.

Further to the above, on September 11, 2025, the Company announced the signing of a landmark agreement, the PSHA, marking a major milestone in the Company's social engagement efforts and reinforcing the strong momentum behind its flagship Warintza Project in southeastern Ecuador. With this signing, the Company has now established formal relationships with all Indigenous organisations surrounding Warintza, in addition to our ongoing collaboration with local authorities. The PSHA, located in the southeast of the province Morona Santiago, is made up of nearly ten thousand people organized into 47 Shuar centers.

In November 2025, the Company announced the results of the PFS which show Warintza to be a globally significant mineral resource with extensive mine life and first quartile cash costs which drives significant Free Cash Flow. The Warintza Project is forecast to have initial capital costs (pre-production) of US$3.7bn (including 15.7% overall contingency) and a 2.6 year post-tax payback period. A maiden mineral reserve estimate was published of 1.3 billion tonnes (Proven and Probable) at 0.41% CuEq (0.31% Cu, 0.02% Mo, 0.04 g/t Au and 1.30 g/t Ag), providing a mine life of 22 years and the 2025 MRE incorporated a 312% increase in Measured plus Indicated Mineral Resources, at a cut-off grade of 0.1% Cu and a NSR cut-off value of US$6.30/t, compared with the published 2024 MRE. The PFS was prepared in conjunction with consultants from Ausenco, Knight Piésold, and AMC Consultants.

The Warintza Project successfully completed a phase change of the environmental license from initial exploration to advanced exploration in mid 2023. In April 2026, Solaris received the technical approval of the Environmental Impact Assessment for its Warintza Project. The approval represents a major permitting milestone and a significant de-risking event for the project following an extensive technical review process conducted by a multidisciplinary team from the Ministry of Environment and Energy. The Company continues to work with the Government of Ecuador on obtaining key permits and licenses for the advancement of the Project.

In December 2022, Solaris and the Government of Ecuador signed an Investment Contract for the Warintza Project which provides for the following protections and incentives for the duration of the title of the Project which extends with renewal to 2066: security of investment, stability of mining law, stability of taxes at a reduced income tax rate of 20% (25% previously), exemption from capital outflow tax (5% previously), exemption from import duties (up to 5% previously), and detailed procedures for dispute resolution and international arbitration protection.

As part of the Royal Gold transaction financing package, the Company issued a 0.3% net smelter return royalty ("NSR royalty") to Royal Gold and a gold stream, where Solaris will deliver gold equivalent to 20 ounces per 1 million pounds of copper produced from the RGLD Gold AOI (as defined in the Stream Agreement). For each ounce of gold delivered under the Stream Agreement, Royal Gold will pay Solaris a purchase price equal to 20% of spot price until 90,000 ounces have been delivered; and 60% of spot price thereafter.

**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 accessible year-round by paved roads and is strategically located next to key infrastructure with easy access to water, power and rail. The Company has recently completed desktop analysis regarding potential development options.

The project is held 60% by the Company and 40% by a subsidiary of Teck.

The joint venture agreement governing the operation and funding of La Verde was formalized effective February 28, 2015 (the "La Verde Agreement"). The La Verde Agreement provides that Solaris is the operator of the project. The La Verde 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.

**Enami Concessions**

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, ENAMI EP ("Solaris 1"). These concessions comprise a land package of ~40,000 hectares adjacent to the Warintza Project and the San Carlos-Panantza porphyry copper-molybdenum deposits in southeastern Ecuador. The new concessions are interpreted to host porphyry copper and epithermal gold potential.

The Company made 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.

Fieldwork at the new ENAMI EP exploration concessions have identified targets with a similar signature across multiple layers of data to Warintza. A number of porphyry copper targets have been identified by open-ended annular magnetic highs enclosing magnetic lows and erosional depressions, consistent with outcropping deposits within the Warintza porphyry cluster for follow-up.

In January 2026, Solaris entered into a second option agreement with ENAMI EP to acquire up to a 100% interest in new exploration areas ("Solaris 2"). New areas 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 programme 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.

**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.

**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. Solaris is focused on obtaining surface access agreements with local landholders and communities for the purposes of permitting exploration programs at both Capricho and Paco Orco.

**Exploration expenditures**

Exploration expenditures consist of both costs that are capitalised as exploration and evaluation assets and costs that are expensed as incurred, in accordance with the Company's accounting policy under IFRS 6 Exploration for and Evaluation of Mineral Resources.

&nbsp;&nbsp;&nbsp;&nbsp;a) Exploration expenditure (IFRS Presentation)

The following tables summarize exploration expenditure by jurisdiction for the periods indicated.

For the three months ended March 31, 2026:

The increase in capitalised expenditures to $6,439 for the three months ended March 31, 2026 (March 31, 2025 $nil) is principally due to the capitalising of costs for the Warintza project following the completion of the PFS.

The decrease in expensed exploration and evaluation costs to $810 for the three months ended March 31, 2026 (March 31, 2025 $12,317) is due to the capitalising of costs for the Warintza project following the completion of the PFS and additionally a reduced level of drilling and associated activity at the Warintza project as the focus was to obtain the technical approval of the EIA.

&nbsp;&nbsp;&nbsp;&nbsp;b) Non-GAAP Financial Measure: Total exploration expenditure

Total exploration expenditure (defined as the sum of capitalised and expensed exploration and evaluation costs) is a non-GAAP financial measure and does not have a standardised meaning under IFRS. This measure may not be comparable to similar measures presented by other companies.

Management uses this measure to evaluate exploration activity across periods, allow comparability given differences in accounting treatment and reflect the full amount of capital allocated to exploration projects. A reconciliation of this measure to the most directly comparable IFRS measures is presented above.

The following tables summarise total exploration expenditure by activity and jurisdiction.

For the three months ended March 31, 2026:

---

The decrease in total exploration expenditure to $7,249 for the three months ended March 31, 2026, from $12,317 for the three months ended March 31, 2025, was primarily due to there being reduced drilling activities and the accompanying cost categories as the focus was to obtain the technical approval of the EIA.

Salaries, studies, geological consulting and support, and travel costs were lower in Ecuador for the three months ended March 31, 2026, compared to the same period in 2025. This was mainly due to the decrease in geological consultants' costs in support of drilling activities, and the accompanying lower mobilization of supplies, materials and personnel to and within the site.

The decrease in site preparation, supplies, field and general costs is commensurate with the decrease in drilling activities with fewer drilling platforms, civil works and site infrastructure, as well as a reduction in supplies and materials consumed at the Warintza Project.

Drilling and drilling-related costs at Warintza, as well as the corresponding assay and analysis costs, decreased for the three months ended March 31, 2026, compared to 2025, due to the Company having conducted a reduced volume of drilling activities in the quarter. The prior year activity saw a higher level of activity principally related to the PFS.

Community relations, environmental and permitting costs decreased in the three months ended March 31, 2026 compared to the same period in 2025, due to the costs in the prior quarter including fees incurred to obtain the advanced exploration environmental licence for the Warintza project.

Reclamation provision represents the estimated costs for restoration and rehabilitation for environmental disturbances at Warintza. For the three months ended March 31, 2026, the reclamation provision expense was lower than the prior year due to the reduced drilling activity with an associated reduction in environmental disturbances and the settlement of reclamation costs.

**Loss from Operations**

**Three Months Ended March 31, 2026 Compared to the Three Months Ended March 31, 2025**

The Company incurred exploration expenses of $810 for the three months ended March 31, 2026 (March 31, 2025 – $12,317). The decrease is mainly attributable to the capitalising of costs for the Warintza Project following the completion of the PFS.

The Company incurred general and administrative expenses of $3,330 for the three months ended March 31, 2026 (March 31, 2025 – $2,217). The increase is mainly due to higher costs in share-based compensation and professional fees.

---

The Company has not generated any income to date other than interest income and a gain on the sale of a royalty interest. Exploration expenses in the three months ended March 31, 2026 were lower than in the three months ended March 31, 2025 due to the capitalising of costs for the Warintza Project following the completion of the PFS .

**Liquidity and Capital Resources**

---

| | | |
|:---|:---|:---|
|  | March 31,<br> 2026 | December 31, <br> 2025 |
| Cash and cash equivalents | $12894 | $25210 |
| Prepaids and other | 737 | 595 |
| Supplies inventory | 176 | 156 |
| Accounts payable and accrued liabilities | 3596 | 7775 |
| Lease liability – current | 40 | 57 |
| Total current assets | 13807 | 25961 |
| Total current liabilities | $4204 | $8400 |

---

Cash used from operating activities during the three months ended March 31, 2026 was $4,844 (March 31, 2025 – $17,252). The decrease in cash used during the three months ended March 31, 2026, compared to the same period in 2025, is primarily due to the capitalising of costs for the Warintza Project following the completion of the PFS.

Cash outflow from financing activities during the three months ended March 31, 2026, was $60 (March 31, 2025 – $243 inflow). The cash outflow in the year was due to finance lease settlements.

Cash outflow from investing activities during the three months ended March 31, 2026 was $7,499 (March 31, 2025 – $511). The increase in cash outflow from investing activities for the three months ended March 31, 2026, relates primarily to the capitalisation of exploration and evaluation expenditures against the Warintza project.

The Company does not generate operating cash flow from a producing mine and has incurred operating losses to date. Based on its current forecasted expenditures, the Company requires additional financing from the third tranche of the Funding Package to fund ongoing operations for the next twelve months.

The condensed consolidated interim financial statements have been prepared in accordance with IFRS applicable to a going concern, 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.

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 with Royal Gold for the Warintza Project (the "Funding Package"). The total cash consideration under the Financing Agreements is $200,000. 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 ("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 PFS and receipt of the EIA technical approval, which will be allocated to the Stream Agreement (received April 2026, see Note 19 of the condensed consolidated interim financial Statements); 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.

Management is committed to diligently managing its liquidity and capital resources, including prioritizing spending in the areas of the business with the highest impact, such as advancing the development of the Company's Warintza Project. Should it be necessary, management has the ability to relatively quickly curtail cash outflows, including exploration expenditures, and to prudently manage the Company's liquidity position to conserve cash resources.

The Company's ability to continue as a going concern is dependent upon the successful execution of its business plan, raising additional capital and/or evaluating strategic alternatives for its mineral property interests.

*Related party arrangement*

 

On January 2, 2020, the Company entered into an arrangement to share office space, equipment, personnel, consultants and various administrative services with other companies related by virtue of certain directors and management in common. The services were provided through a management company equally owned by each company party to the arrangement. Costs incurred by the management company were allocated and funded by the shareholders of the management company based on time incurred and use of services. All of the parties jointly entered into a rental agreement for office space. When the Company's participation in the arrangement terminated, the Company was obligated to pay its share of the rent payments for the remaining term of the office space rental agreement. On January 1, 2025, the Company terminated the arrangement to share office space, equipment, personnel, consultants and various administrative services with other companies related by virtue of certain directors and management in common. The agreed settlement cost associated with the termination of the agreement was $104.

**MATERIAL Accounting Policies and Estimates**

In preparing the accompanying condensed consolidated interim financial statements in conformity with IFRS, management has made judgements, estimates and assumptions that affect the application of the Company's accounting policies and the reported amounts of assets, liabilities, income and expense. Actual results may differ. All estimates and underlying assumptions are reviewed on an ongoing basis. Revisions are recognized in the period in which the estimates are revised and in any future periods affected. Information about critical judgements and estimates in applying accounting policies that have the most significant effect on amounts recognized in the condensed consolidated interim financial statements are the same as those described in the consolidated annual financial statements for the year ended December 31, 2025.

Judgements and estimates that have the most significant effect on the amounts recognized in the Company's condensed consolidated interim financial statements are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a) Accounting for streaming & royalty arrangements

Management has applied judgment in the assessment that the Stream Agreement (Note 8 of the condensed consolidated interim financial statements) constitutes a contract for the future sale of commodities to the counterparty. The contract will be settled through the delivery of commodity and in no event settled in cash except in the event of specific non-operational scenarios. The deposit is therefore recorded as deferred revenue and is not a financial liability. Management assessed that the contract contained a significant financing component, which required making estimates, with information reasonably available to the parties at contract inception, of the quantity and the cash selling price of the promised goods to be delivered under the Stream Agreement in order to determine the implicit interest rate of the agreement. These estimates are subject to variability and may have an impact on the timing and amount of revenue recognized. Management exercised judgment in applying IFRS 15, as the treatment of the deposit as a contract liability is a key judgment and is based on the expected delivery of the Company's future production.

The key estimates used to arrive at the implicit interest rate in the agreement are:

● based on an internal mine development model with a mine start date of 2030, with a 55 year mine life

● gold price of $2,904 per ounce

● discount rate of 4.6%

The value of the Royalty Agreement and Stream Agreement was based on the separate contracts and cash received for each (Note 8 of the condensed consolidated interim financial statements). Analysis was performed based on the internal mine development model referenced above, considering multiple scenarios which impact the royalty contract metrics and returns to support the values attributed in the contracts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) Reclamation provision

The ultimate costs for reclamation and rehabilitation are uncertain, and cost estimates can vary in response to many factors, including estimates of the nature, extent and timing of rehabilitation activities, technological changes, regulatory changes, changes in inflation rates, the risk-free interest rate used for discounting future cash flows, foreign exchange rates, and estimates of the underlying currencies in which the provisions will ultimately be settled. The Company estimates its costs based on studies using current restoration standards and techniques, and the provision at the reporting date represents management's best estimate of the present value of the future rehabilitation costs required. Significant assumptions related to the reclamation provision are disclosed in Note 5 of the condensed consolidated interim financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c) Valuation of exploration and evaluation assets

The application of the Company's accounting policy for exploration and evaluation assets requires estimates in determining whether it is likely that future economic benefits will flow to the Company, which may be based on assumptions about future events or circumstances. Capitalized acquisition costs are assessed for impairment at least annually or when facts and circumstances suggest that the carrying amount of an exploration and evaluation asset may exceed its recoverable amount. Judgement is required in determining whether indicators of impairment exist, including factors such as the period for which the Company has the right to explore, expected renewals of exploration rights, whether expenditures on further exploration and evaluation of resource properties are planned, results of exploration and evaluation activities on the exploration and evaluation assets and future commodity prices.

A lack of expenditure on the La Verde asset in prior years was deemed to be an indictor of impairment as at December 31, 2025 and an impairment test was performed accompanied by an independent valuation of the La Verde asset. The fair market value was estimated using the market approach, specifically using the comparable in-situ resource multiples observed for guideline public companies and comparable transactions. There was no impairment resulting from the test. There were no indicators of impairment identified for the Company's other Exploration and Evaluation assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d) Going concern evaluation

As discussed in Note 1 of the condensed consolidated interim financial statements, these have been prepared under the assumptions applicable to a going concern. If the going concern assumption were not appropriate for these condensed consolidated interim financial statements, then adjustments would be necessary to the carrying value of assets and liabilities, the reported expenses, and the statement of financial position classifications used and such adjustments could be material. The Company reviews the going concern assessment at the end of each reporting period. The Company's assessment of its ability to continue as a going concern requires significant judgement about whether there are material uncertainties that may cast significant doubt about the Company's ability to continue as a going concern. Based on its current forecasted expenditures, the Company requires the additional financing from the third tranche of the 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e) Mineral Reserves and Resources

Mineral reserve and resource estimates are prepared by Qualified Persons in compliance with NI 43-101 standards. These estimates rely on expert judgment regarding geological data, mining methods, and production scheduling, alongside key assumptions for costs and metal pricing. Any updates to this data or these assumptions can alter the economic viability of our projects, leading to revisions that may impact asset valuations, depreciation rates, tax strategies, and restoration provisions.

**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 ("Board") 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 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) 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 a change of $411 (December 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 .

**Capital management**

The Company's primary objective when managing capital is to ensure that it will be able to continue as a going concern and that it has the ability to satisfy its capital obligations and ongoing operational expenses, as well as having sufficient liquidity to fund suitable business opportunities as they arise.

The Company manages its capital structure and makes adjustments to it as necessary in light of economic conditions. In order to maintain the capital structure, the Company may, from time to time, issue or buy back equity, issue or repay debt, or sell assets. The Company, upon approval from its Board, intends to balance its overall capital structure through a combination of equity financing, debt and other forms of financing. The Company did not have any externally imposed restrictions as at March 31, 2026. To effectively manage its capital requirements, the Company has in place a planning and budgeting process to help determine the funds required to ensure the Company has appropriate liquidity to meet its business activities, including planned corporate expenditures, exploration expenses, as well as the development activities for the Warintza Project.

**Risks and Uncertainties**

An investment in the Common Shares is highly speculative and subject to a number of risks and uncertainties. Only those persons who can bear the risk of the entire loss of their investment should invest in the Common Shares. An investor should carefully consider the risks and the other information filed with the Canadian securities regulators before investing in the Common Shares. A discussion of these risks and other factors that may affect the Company's actual results, performance, achievements or financial position is contained in the Company's annual MD&A dated March 25, 2026 and in the Company's Annual Information Form, each filed under the Company's profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

**Disclosure Controls and Procedures and Internal Control Over Financial Reporting**

The Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") have designed or caused to be designed under their supervision the Company's disclosure controls and procedures ("DC&P") to provide reasonable assurance that material information regarding the Company is accumulated and communicated to the Company's management, including its CEO and CFO, in a timely manner. In addition, the CEO and CFO have designed or caused to be designed under their supervision ICFR to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements, as well as an evaluation on whether there were changes to its ICFR during most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's ICFR. The control framework used to design the Company's ICFR is based on the 2013 control framework developed by the Committee of Sponsoring Organizations of the Treadway Commission.

---

For the three months ended March 31, 2026, the DC&P have not been designed effectively to provide reasonable assurance that material information relating to the Company is made known to the CEO and CFO, particularly during the period in which the relevant annual filings are prepared and the information required to be disclosed by the Company in its filings or other reports filed or submitted by it under securities legislation is recorded, processed, summarized and reported within the time periods specified. Given the identified material weakness as described below, management concluded that the Company's DC&P and ICFR was not effective as of March 31, 2026.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that its objectives are met. Due to inherent limitations in all such systems, no evaluations of controls can provide absolute assurance that all control issues, if any, within a company are detected on a timely basis.

**Material Weakness**

As previously disclosed in our MD&A 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.

The material weakness related to the design and implementation of 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 expenditures on exploration and evaluation assets within the condensed consolidated interim statement of cash flows, and (iv) calculation of the tax provision. These control deficiencies resulted in errors that were identified and corrected by management.

During the three months ended March 31, 2026, the Company continued to implement its remediation plan to address the material weakness. While progress has been made, the material weakness cannot be considered remediated until the enhanced controls have operated for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively.

Although the material weakness did not result in any material misstatement of our condensed consolidated interim financial statements for the three months ended March 31, 2026, or prior periods, it could result in a material misstatement of account balances or disclosures if not fully remediated. Accordingly, management has concluded that the material weakness continues to exist as of March 31, 2026.

Management, under the oversight of the Audit Committee, will continue to monitor the effectiveness of its remediation efforts and will refine its plan as necessary.

**Changes in Internal Control Over Financial Reporting**

National Instrument 52-109 – *Certification of Disclosure in Issuers' Annual and Interim Filings* requires Canadian public companies to disclose any changes in ICFR during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, ICFR. No material changes were made to internal controls during the fiscal quarter ended March 31, 2026.

**Qualified Person**

A "Qualified Person" is as defined by the NI 43-101 of the Canadian Securities Administrators. The named Qualified Person(s) have verified the data disclosed, including sampling, analytical, and test data underlying the information or opinions contained in this MD&A in accordance with standards appropriate to their qualifications.
