Rhea-AI Filing Summary

Solaris Resources Inc. (SLSR) recorded a $13.554 million net loss for the nine months ended September 30, 2026, compared with $32.941 million a year earlier. Exploration expense was $2.753 million versus $30.668 million, largely because Warintza project costs were capitalized after the pre-feasibility study; exploration and evaluation assets were $54.054 million, compared with $26.282 million at December 31, 2025.

Royal Gold paid Solaris total cash consideration of $200 million under the Warintza funding package, including a $50 million third installment received November 6, 2026. At September 30, cash was $42.044 million. Cash generated from operating activities was $39.812 million for the nine months, primarily due to receipt of the second Royal Gold tranche.

Solaris does not generate operating cash flow from a producing mine and said it requires additional financing for the next twelve months. The company stated that material uncertainty casts significant doubt on its ability to continue as a going concern.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

At September 30, the Royal Gold stream had $143,181 thousand in deferred revenue tied to future gold deliveries.

This Form 6-K furnishes Solaris’ interim financial statements and MD&A for the nine months ended September 30, 2026, and incorporates both exhibits into its Form F-10 and Form S-8 registration statements.

Royal Gold has paid Solaris total cash consideration of $200,000 thousand under the package. Under the stream, Solaris must deliver gold equal to 20 ounces per 1 million pounds of copper produced from a defined area; Royal Gold pays 20% of spot price per ounce until 90,000 ounces are delivered, then 60%.

The separate royalty gives Royal Gold a 0.3% net smelter return royalty on metal production from a defined area; it increases 0.0375% annually, up to 0.6%, until first gold delivery or eight years after closing, whichever comes first.

At September 30, 2026, deferred revenue for the stream stood at $143,181 thousand; the filing says the final $50,000 thousand installment was received on November 6, 2026, after that balance-sheet date.

Key Terms

going concern, deferred revenue, gold stream, net smelter return royalty, +2 more

6 terms

going concern financial

"material uncertainty exists that casts significant doubt about the Company’s ability to continue as a going concern"

Going concern is the accounting assumption that a company will keep operating and meeting its obligations for the foreseeable future. The phrase matters most when a company or its auditors disclose substantial doubt about it, a formal warning that the business may not have enough resources to continue without raising money, restructuring, or selling assets. That language in a filing or press release signals elevated financial risk.

deferred revenue financial

"The Company recorded the Stream Upfront Payment as deferred revenue"

Cash a company has already received for goods or services it has promised but not yet delivered; it's recorded as a liability because the company still owes that product, service, or future revenue recognition. For investors, deferred revenue signals upcoming work or deliveries that will convert into reported sales over time and affects short-term obligations, cash flow quality, and how quickly a firm can grow recognized revenue—think of it like prepaid subscriptions or gift cards a business must honor later.

gold stream financial

"a gold stream, where Solaris will deliver gold equivalent"

A gold stream is a contract where an investor or firm pays cash up front to a mining company in exchange for the right to buy a portion of that mine’s future gold at a set, usually below-market, price or to receive a fixed share of production. It matters to investors because it provides miners with immediate funding without issuing traditional debt or equity, while the streamer gains long-term exposure to gold at a predictable cost — a trade-off between lower purchase price and limited upside if gold prices rise sharply.

net smelter return royalty financial

"a 0.30% net smelter return royalty to Royal Gold"

A net smelter return (NSR) royalty is a contractual right to receive a percentage of the revenue from minerals sold after they are processed and refined, with common deductions for transportation and refining fees. Investors care because an NSR provides a predictable slice of mining project income without owning the mine, so it affects expected cash flow, risk exposure to commodity prices, and the valuation of both the royalty and the operating project—similar to collecting a portion of rent after paying building maintenance costs.

pre-feasibility study technical

"In November 2025, the Company announced the results of the PFS"

A pre-feasibility study is an initial assessment that evaluates whether a proposed project or investment idea is worth exploring further. It involves examining basic factors like costs, potential benefits, and possible challenges, similar to conducting a preliminary check before deciding to invest more time and resources. This helps investors determine if pursuing the project further is practical and likely to be successful.

non-GAAP financial measure financial

"Total exploration expenditure is a non-GAAP financial measure"

A non-GAAP financial measure is a way companies present their financial results that excludes certain expenses or income to show how they believe their core business is performing. It matters because it can give a clearer picture of how the company is really doing, but it can also be used to make results look better than they actually are.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2026 and 2025

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

1. Nature of operations AND GOING CONCERN

Notes to the Condensed Consolidated Interim Financial Statements

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 Company published the results of a pre-feasibility study (“PFS”) for the Warintza project. The Company has not yet determined whether its 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 project financing to fund its business activities, including planned corporate expenditures, exploration expenses, and 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 issuance of common shares and broader project financing initiatives 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.

As at September 30, 2026, the Company had cash and cash equivalents of $42,044. 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 royalty agreement (the “Royalty Agreement”) (collectively, the “Financing Agreements”). Royal Gold has paid Solaris 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 and $10,000 allocated to the Royalty 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, received on April 14, 2026 and allocated to the Stream as per the contract; 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, received on November 6, 2026 (Note 19) and allocated to the Stream as per the contract.

Based on its current forecasted expenditures, the Company requires additional financing 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 carrying values of assets and liabilities, expenses, and financial position classifications that would be necessary if the going concern assumption were not appropriate. 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 and nine months ended September 30, 2026 and 2025

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

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. 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. 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 0.3375% net smelter return royalty covering a total of 18,600 hectares.

c) ENAMI Concessions

(i) ENAMI 1

Solaris has entered into an option agreement to acquire up to a 100% interest in 10 new exploration concessions (“Solaris 1”) 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 entered into a second option agreement with ENAMI EP to acquire up to a 100% interest in new exploration areas (“Solaris 2”) including an upfront payment of $250. 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) a proposed minimum exploration program of $25,000 over the four-year exploration phase; (ii) up to $1,750 subject to the achievement of certain milestones and (iii) 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 an 88,900 hectare lead, zinc and silver property.

The reclamation provision represents the estimated costs for restoration and rehabilitation for environmental disturbances at Warintza, estimated to be incurred from 2027. The total undiscounted and uninflated estimated cash flows required to settle these obligations as at September 30, 2026 are $5,385 (December 31, 2025 – $4,322), which have been inflated at an average rate of 2.83% per annum (December 31, 2025 – 2.43%) and discounted at an average rate of 4.54% (December 31, 2025 – 3.55%).

Restricted cash of $563 (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 period represents a guarantee paid to ENAMI EP relating to the expansion of the Warintza district (Note 4).

8. WARINTZA PROJECT FINANCING

On December 11, 2023, the Company entered into a financing package with OMF Fund IV SPV D LLC and OMF Fund IV SPV E LLC (collectively “OMF”), entities managed by Orion, to provide up to approximately $80,000 in aggregate funding for the advancement of the Warintza project in Ecuador. The financing package is comprised of a $60,000 Senior Loan, a subscription for $10,000 in common shares with a commitment for $10,000 in additional equity financing and a copper offtake agreement to purchase concentrate produced by the Warintza project. On December 19, 2023, the Company also signed a molybdenum offtake agreement with OMF.

a) Senior Loan – OMF Fund IV SPV D LLC

A first advance of $30,000 was received on December 21, 2023. An additional advance of $15,000 was received on September 13, 2024. A final advance of $15,000 was received on May 14, 2025.

Amounts drawn on the Senior Loan bear interest payable quarterly at the higher of (a) adjusted term secured overnight financing rate (“SOFR”) and (b) 2.00%, plus either 7.00% per annum in the case of interest paid in cash, or 7.50% in the case of interest that is accrued to the loan balance in accordance with the Senior Loan Facility agreement. At May 21, 2025, when fully repaid, the Senior Loan 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 accrue it to the principal amount of the Senior Loan and pay it upon maturity. The interest until repayment was accrued to the principal amount of the Senior Loan Facility.

On May 21, 2025, the Company entered into a financing agreement with Royal Gold, which provided the funding required to repay the senior loan facility, as outlined in (c) below.

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.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2026 and 2025

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

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.

c) Funding package with Royal Gold

On May 21, 2025, the Company entered into a Funding Package with 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 and a Royalty.

Royal Gold has paid 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 and $10,000 allocated to the Royalty 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, received on April 14, 2026 and allocated to the Stream as per the contract; 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, received on November 6, 2026 (Note 19) and allocated to the Stream as per the contract.

Under the terms of the Stream, 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, 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, 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; or eight years following the closing date.

The Company’s obligations under the Stream 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 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 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 and related documents are guaranteed 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, (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 are to guarantee and/or secure the obligations under the Royalty.

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.

Solaris Resources Inc.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2026 and 2025

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

Deferred revenue consists of: 1) initial Stream Upfront Payment received by the Company for future delivery of gold under the terms of the Stream, and 2) a significant financing component of the Stream 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. 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, restricted cash 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 $42,969 represents the maximum exposure to credit risk.

Notes to the Condensed Consolidated Interim Financial Statements

For the three and nine months ended September 30, 2026 and 2025

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

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 September 30, 2026, the Company had contractual cash flow commitments as follows:

		< 1 Year				1-3 Years				4-5 Years				> 5 Years				Total
Accounts payable and accrued liabilities		$	6,855			$	–			$	–			$	–			$	6,855
Lease liabilities			170				223				–				–				393
Other long-term liabilities			–				–				–				369				369
Capitalized exploration expenses and other			1,083				–				–				–				1,083
		$	8,108			$	223							$	369			$	8,700

c) Foreign currency risk

The Company is exposed to currency risk on transactions and balances in currencies other than the functional currency. At September 30, 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 September 30, 2026, cash of $ 38,511 (December 31, 2025 – $19,257), and accounts payable and accrued liabilities of $443 (December 31, 2025 - $88) are denominated in the US dollar. For the nine months ended September 30, 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 $1,964 (nine months ended September 30, 2025 – $1,385).

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.

15. Fair value measurements

The carrying values of cash and cash equivalents, restricted cash and accounts payable and accrued liabilities approximate fair value due to their short terms to maturity. There were no transfers between fair value levels in the periods presented.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2026 and 2025

(Expressed in thousands of United States dollars, unless otherwise noted)

The following activities and developments were achieved during the quarter:

● On September 10, 2026, Solaris published the press release entitled Communities Finalise Life Plans Alongside Renewed Shuar Agreements as Warintza Continues to Advance De-Risking Activities. Solaris announced the renewal of its cooperation agreements with the Interprovincial Federation of Shuar Centers and the Pueblo Shuar Arutam Organization. The Warints and Yawi communities also finalized their respective Community Life Plans, subject to customary community approval. The Company further reported continued progress across permitting, technical studies and project de-risking activities, including technical drilling, geotechnical and hydrogeological investigations, laboratory testing and road maintenance supporting reliable year-round access.

Subsequent to quarter-end:

● On November 9, 2026, Solaris announced that it had received the third 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, that further strengthens the Company’s balance sheet and provides additional financial flexibility to advance key development activities at Warintza.

OUTLOOK

Solaris will continue to advance the de-risking activities required to support the development of Warintza. The Project will advance through the remaining stages of Ecuador’s environmental licensing and development approval process, including the Government-led FPIC process.

The Company will continue technical drilling and advance the Feasibility Study and associated technical workstreams, including mine and infrastructure design, tailings and water-management solutions, geotechnical and hydrogeological studies, and further refinement of capital and operating cost estimates.

Solaris will also continue work to unlock value across its broader 100%-owned land package of more than 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).

The property includes nine metallic mineral concessions covering 26,773 hectares.

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 demonstrates 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 the Interprovincial Federation of Shuar Centers (“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.

(Expressed in thousands of United States dollars, unless otherwise noted)

Further to the above, on September 11, 2025, and subsequently renewed in September 2026, the Company announced the signing of a landmark agreement with the Pueblo Shuar Arutam organization (“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 0.30% 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. The NSR 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; or eight years following the closing date.

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, utilizing underground mining methods.

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

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 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.

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, 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 (“Solaris 1”), 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 has 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.

On January 28, 2026, Solaris entered into a second option agreement with ENAMI EP to acquire up to a 100% interest in new exploration areas (“Solaris 2”) including an upfront payment of $250. 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) a proposed minimum exploration program of $25,000 over the four-year exploration phase; (ii) up to $1,750 subject to the achievement of certain milestones and (iii) 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 an 88,900-hectare lead, zinc and silver property. Solaris has obtained surface access agreements with local landholders and communities and is in the process of permitting exploration programs at both Capricho and Paco Orco.

		$	26,012			$	129			$	81			$	3,955			$	303			$	30,480

1	Peru – Warintza expenditure includes costs for shared technical services, performed in Lima.
2	The $188 reduction in asset value following the sale of royalty interest is not included in Ecuador exploration expenses for the three and nine months ended September 30, 2025.

The increase in capitalized expenditures to $11,551 and $27,772 for the three and nine months ended September 30, 2026 from $(188) for the three and nine months ended September 30, 2025 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 $748 and $2,753 for the three and nine months ended September 30, 2026 from $9,501 and $30,668 for the three and nine months ended September 30, 2025 is due to the capitalising of costs for the Warintza project following the completion of the PFS.

(b) Non-GAAP Financial Measure: Total exploration expenditure

Total exploration expenditure (defined as the sum of capitalized and expensed exploration and evaluation costs) is a non-GAAP financial measure and does not have a standardized 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 summarize total exploration expenditure (defined as the sum of capitalized and expensed exploration and evaluation costs) by activity and jurisdiction.

^{1 Peru – Warintza expenditure includes costs for shared technical services, performed in Lima.}

^{2 Ecuador exploration expenses for the three and nine months ended September 30, 2025, do not include the $188 reduction in asset value following the sale of royalty interest.}

The increase in total exploration expenditure to $12,299 for the three months ended September 30, 2026, from $9,501 for the three months ended September 30, 2025, was primarily due to a ramp up in drilling activity at Warintza.

Total exploration expenditure of $30,525 for the nine months ended September 30, 2026 was broadly in line with $30,668 for the nine months ended September 30, 2025.

Salaries, studies, geological consulting and support, and travel costs were lower in Ecuador for the three and nine months ended September 30, 2026, compared to the same periods in 2025. This was mainly due to the decrease in geological consultants’ costs related to technical studies associated with the completion of the PFS in 2025.

The increase in site preparation, supplies, field and general costs is commensurate with the ramp up in drilling activities in the three and nine months ended September 30, 2026 with additional drilling platforms, civil works and site infrastructure, as well as an increase in supplies and materials consumed at the Warintza Project.

Drilling and drilling-related costs at Warintza increased for the three and nine months ended September 30, 2026, compared to 2025, due to the Company having conducted an increased volume of drilling activities in the quarter. This resulted in an increase in associated costs principally related to fuel and helicopter costs.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2026 and 2025

(Expressed in thousands of United States dollars, unless otherwise noted)

Community relations, environmental and permitting costs decreased in the three and nine months ended September 30, 2026 compared to the same periods in 2025, due to the costs in the prior quarters 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 and nine months ended September 30, 2026, the reclamation provision expense was higher than the prior year due to the increase in drilling activity with an associated increase in environmental disturbances.

Loss from Operations

Three and Nine Months Ended September 30, 2026 Compared to the Three and Nine Months Ended September 30, 2025

The Company incurred exploration expenses of $748 and $2,753 for the three months and nine months ended September 30, 2026 (three and nine months ended September 30, 2025 – $9,501 and $30,668 respectively). 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 $2,821 and $8,863 for the three months and nine months ended September 30, 2026 (three and nine months ended September 30, 2025 – $2,250 and $10,033 respectively). The increase for the three-month period was primarily attributable to higher share-based payment charges. The decrease for the nine-month period primarily reflected lower professional fees, as the corresponding period in 2025 included fees incurred in connection with the Royal Gold funding package.

Summary of Quarterly Financial Information

The Company’s quarterly financial statements are reported under IFRS issued by the IASB, as applicable to interim financial reporting. The following table provides highlights from the quarterly results of the Company’s unaudited condensed consolidated interim financial statements for the past eight quarters.

		2026 Q3				2026 Q2				2026 Q1				2025 Q4

Net loss per share – basic and diluted		$	0.07				0.03				0.10				0.16

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 nine months ended September 30, 2026 were lower than the nine months ended September 30, 2025, due to the capitalising of costs for the Warintza Project following the completion of the PFS.

Liquidity and Capital Resources

Cash used in operating activities during the three months ended September 30, 2026 was $2,056 (September 30, 2025 – $11,874), and was attributable to general and administration costs and exploration and evaluation expenses on Solaris’ assets in Peru and Mexico. Cash generated from operating activities during the nine months ended September 30, 2026 was $39,812, (September 30, 2025 – $55,572), primarily due to receipt of the second tranche of Royal Gold funding.

Cash outflow from financing activities during the three and nine months ended September 30, 2026 was $60 and $185, respectively (September 30, 2025 – $64 and $51,737, respectively). The cash outflow in the period is primarily due to finance lease settlements.

Cash outflow from investing activities during the three and nine months ended September 30, 2026 was $9,931 and $22,935, respectively (September 30, 2025 – $71 (inflow) and $937, respectively) and was primarily due 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 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.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2026 and 2025

(Expressed in thousands of United States dollars, unless otherwise noted)

As at September 30, 2026, the Company had cash and cash equivalents of $42,044. 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 has paid 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, allocated to the Stream Agreement (received April 2026); 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, received on November 6, 2026 (see Note 19 of the condensed consolidated interim financial Statements) and 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. As a result, material uncertainty exists that casts significant doubt about the Company’s ability to continue as a going concern.

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.

Solaris Resources Inc.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2026 and 2025

(Expressed in thousands of United States dollars, unless otherwise noted)

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:

a) Accounting for streaming and 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.

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.

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.

d) Going concern evaluation

As discussed in Note 1 of the condensed consolidated interim financial statements, the condensed consolidated interim financial statements have been prepared under the assumptions applicable to a going concern. If the going concern assumption were not appropriate for the 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. The Company must determine whether sufficient financing will be obtained in the near term.

(Expressed in thousands of United States dollars, unless otherwise noted)

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 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, restricted cash 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 $42,969 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 September 30, 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 September 30, 2026, cash of $ 38,511 (December 31, 2025 – $19,257), and accounts payable and accrued liabilities of $443 (December 31, 2025 - $88) are denominated in the US dollar. For the nine months ended September 30, 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 $1,964 (nine months ended September 30, 2025 – $1,385).

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.

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 (discussed in Note 1 of the condensed consolidated interim financial statements). As at September 30, 2026, the Company had cash and cash equivalents of $42,044.

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 September 30, 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 internal control over financial reporting ("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 September 30, 2026, the DC&P have 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 and remediation process as described below, management could not conclude that the Company’s DC&P and ICFR were operating effectively as of September 30, 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 September 30, 2026, management continued implementation of the remediation plan designed to address the previously identified material weakness. Progress during the quarter included further enhancement of key financial reporting controls, continued refinement of process documentation, Risk and Control Matrices (RACMs), governance arrangements and preparations for SOX Section 404 compliance.

Solaris Resources Inc.

Management’s Discussion and Analysis

For the three and nine months ended September 30, 2026 and 2025

(Expressed in thousands of United States dollars, unless otherwise noted)

While significant progress towards the remediation of the material weakness noted above has been made, management has concluded that the material weakness was not fully remediated as of September 30, 2026. The material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. No additional material weaknesses were identified during the quarter.

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 have materially affected, or is reasonably likely to materially affect, ICFR. No material changes were made to internal controls in the three months ended September 30, 2026.

1. Review: I have reviewed the interim financial report and interim MD&A (together, the “interim filings”) of Solaris Resources Inc. (the “issuer”) for the interim period ended September 30, 2026.

2. No misrepresentations: Based on my knowledge, having exercised reasonable diligence, the interim filings do not contain any untrue statement of a material fact or omit to state a material fact required to be stated or that is necessary to make a statement not misleading in light of the circumstances under which it was made, with respect to the period covered by the interim filings.

3. Fair presentation: Based on my knowledge, having exercised reasonable diligence, the interim financial report together with the other financial information included in the interim filings fairly present in all material respects the financial condition, financial performance and cash flows of the issuer, as of the date of and for the periods presented in the interim filings.

4. Responsibility: The issuer’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (DC&P) and internal control over financial reporting (ICFR), as those terms are defined in National Instrument 52-109 Certification of Disclosure in Issuers’ Annual and Interim Filings, for the issuer.

5. Design: Subject to the limitations, if any, described in paragraphs 5.2 and 5.3, the issuer’s other certifying officer(s) and I have, as at the end of the period covered by the interim filings

(a) designed DC&P, or caused it to be designed under our supervision, to provide reasonable assurance that

(i) material information relating to the issuer is made known to us by others, particularly during the period in which the interim filings are being prepared; and

(ii) information required to be disclosed by the issuer in its annual filings, interim filings or other reports filed or submitted by it under securities legislation is recorded, processed, summarized and reported within the time periods specified in securities legislation; and

(b) designed ICFR, or caused it to be designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with the issuer’s GAAP.

5.1 Control framework: The control framework the issuer’s other certifying officer(s) and I used to design the issuer’s ICFR is Internal Control – Integrated Framework (2013) published by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

5.3 Limitation on scope of design: N/A

6. Reporting changes in ICFR: The issuer has disclosed in its interim MD&A any change in the issuer’s ICFR that occurred during the period beginning on July 1, 2026 and ended on September 30, 2026 that has materially affected, or is reasonably likely to materially affect, the issuer’s ICFR.
