In certain circumstances, the sum of the tax and the interest charge may exceed the total amount of proceeds realized on the disposition, or the amount of excess distribution received, by the U.S. Holder. Subject to certain limitations, these tax consequences may be altered if a U.S. Holder makes a timely and effective QEF Election or a Mark-to-Market Election (each as defined below under the heading “Certain U.S. Federal Income Taxation Considerations – Default PFIC Rules under Section 1291 of the Code”). A U.S. Holder who makes a QEF Election generally must report on a current basis its share of our net capital gain and ordinary earnings for any year in which we are a PFIC, whether or not we distribute any amountsamount to our shareholders. We will make available to U.S. Holders, upon their written request, information as to our status as a PFIC, as reasonably determined by us, and will provide to a U.S. Holder all information and documentation that a U.S. Holder making a QEF Election with respect to us that is required to obtain for U.S. federal income tax purposes in the event we are a PFIC. We may provide such information on our website. A U.S. Holder who makes the Mark-to-Market Election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the U.S. Holder’s tax basis therein.

We have limited financial resources. We currently generate no mining operating revenue and must primarily finance exploration activity and the development of mineral projects by other means. Once our share of the funding originally contributed by South32 to Ambler Metals (part of which was returned to us in 2024) has been expended, ourOur ability to continue exploration, development and production activities, if any, will depend on our ability to obtain additional external financing. Any unexpected costs, problems or delays could severely impact our ability to continue exploration and development activities. The failure to meet ongoing obligations on a timely basis could result in a loss or a substantial dilution of our interests in projects.

Reworded

As the Upper Kobuk Mineral Projects are located in a remote area, exploration, development and production activities may be limited and delayed by inclement weather and a shortened exploration season. The exploration of the UKMP Projects haswas also been impacted by COVID-19.COVID-19 and any future pandemic events may have a similar impact on the UKMP Projects.

Reworded

We cannot provide assurance that title to our properties will not be challenged. We (through our interest in Ambler Metals) indirectly own mineral claims which constitute our property holdings. We may not have, or may not be able to obtain, all necessary surface rights to develop a property. Title insurance is generally not available for mineral properties and our ability to ensure that we have obtained a secure claim to individual mining properties may be severely constrained. Our mineral properties may be subject to prior unregistered agreements, transfers or claims, and title may be affected by, among other things, undetected defects. We have not conducted surveys of all of the claims in which we hold direct or indirect interests. A successful claim contesting our title to a property will cause us to lose our rights to explore and, if warranted, develop that property or undertake or continue production thereon. This could result in our not being compensated for our prior expenditures relating to the property. In addition, our ability to continue to explore and develop the property may be subject to agreements with other third parties including agreements with native corporations and first nations groups, for instance, the lands at the Upper Kobuk Mineral Projects are subject to the NANA Agreement (as more particularly described under "History of Trilogy - Agreement with NANA Regional Corporation").

Most exploration projects do not result in the discovery of commercially mineable ore deposits, and no assurance can be given that any anticipated level of recovery of ore reserves, if any, will be realized or that any identified mineral deposit will ever qualify as a commercially mineable (or viable) ore body which can be legally and economically exploited. Estimates of mineral reserves, mineral resources, mineral deposits and production costs can also be affected by such factors as environmental permitting regulations and requirements, weather, environmental factors, unforeseen technical difficulties, the metallurgy of the mineralization forming the mineral deposit, unusual or unexpected geological formations and work interruptions. If current exploration programs do not result in the discovery of commercial ore, we may need to write-off part or all of our investment in our existing exploration stage properties and may need to acquire additional properties.

Certain of our directors and officers also serve as directors or officers, in other companies involved in natural resource exploration and development or mining-related activities, including, in particular, NovaGold.activities. To the extent that such other companies may participate in ventures in which we may participate in, or in ventures which we may seek to participate in, our directors and officers may have a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In all cases where our directors and officers have an interest in other companies, such other companies may also compete with us for the acquisition of mineral property investments. Any decision made by any of these directors and officers involving Trilogy will be made in accordance with their duties and obligations to deal fairly and in good faith with a view to the best interests of Trilogy and its shareholders. In addition, each of the directors is required to declare and refrain from voting on any matter in which these directors may have a conflict of interest in accordance with the procedures set forth in the Business Corporations Act (British Columbia) and other applicable laws. In appropriate cases, the Company will establish a special committee of independent directors to review a matter in which several directors, or management, may have a conflict. Nonetheless, as a result of these conflicts of interest, the Company may not have an opportunity to participate in certain transactions, which may have a material adverse effect on the Company’s business, financial condition, results of operation and prospects.

Added

The consummation of the transactions contemplated by the binding letter of intent with the U.S. Government and the U.S. Government’s ownership of significant equity interests in the Company may subject the Company and it stockholders to a number of additional risks and uncertainties, any of which could have a material adverse effect on the Company’s business, financial condition and results of operations or adversely impact the interests of our other shareholders.

Added

The binding letter of intent entered into on October 6, 2025 with the DOW, led by the Office of the Undersecretary of Defense for Acquisitions and Sustainment (OUSD (A&S)) and the Office of Strategic Capital (OSC), for the Strategic Investment, which provides that the DOW will purchase from the Company 8,215,570 units at a price of $2.17 per unit for an aggregate purchase price of approximately $17.8 million. Each unit is comprised of one common share of Trilogy and 3/4 of a 10-year Trilogy Warrant. Each Trilogy Warrant will be exercisable following completion of construction of the Ambler Road at an exercise price of $0.01 to acquire one common share of Trilogy. Additionally, the DOW will purchase from South32, the Company’s joint venture partner at Ambler Metals, at a price of approximately $17.8 million 8,215,570 common shares of Trilogy that South32 currently holds and a 10-year call option to acquire an additional 6,161,678 common shares of Trilogy from South32 at a price of $0.01 per share, exercisable following completion of construction of the Ambler Road. The aggregate 16,431,140 shares to be issued and/or transferred to the DOW pursuant to the transactions above represents approximately 10% of the Company’s then issued and outstanding common shares. The Company and South32 will reinvest the entire proceeds from the Strategic Investment in Ambler Metals to advance the exploration and development of the UKMP. Unitl October 6, 2028, the DOW shall have a three-year right to appoint one independent third-party director with relevant corporate governance experience to the board of directors of Trilogy, subject to the approval of the Trilogy board of directors, not to be unreasonably withheld. Finally, the letter of intent contains covenants to act in good faith regarding (i) a framework agreement among interested parties to establish the basis on which the Ambler Road can be permitted, financed and constructed, (ii) the DOW’s help to facilitate financing required for the construction of the Ambler Road in coordination with the State of Alaska, and (iii) certain permitting matters. Finally, the binding letter of intent provides for limits on the Company’s incurrence of indebtedness for the next three years in excess of $1 billion. The transaction is expected to close following the reauthorization of the Defense Production Act by the United States Congress and the completion by the U.S. government of its Foreign Ownership, Control, or Influence (FOCI) review; provided however, that if these conditions have not occurred prior to March 31, 2026 the letter of intent will terminate.

Added

The closing of the Strategic Investment and the associated receipt of funds depends on the availability of appropriations from the legislative branch of the U.S. government and the ability of the executive branch of the U.S. government to obtain the funding and support contemplated by the transaction. The legislative, judicial or executive branches of the U.S. government could determine in the future that all or a portion of the transactions were unauthorized, void or voidable. The issuance of common shares to the U.S. government at a discount to the current market price is dilutive to existing shareholders, and shareholders may suffer significant additional dilution if the conditions to the Trilogy Warrant are triggered and the Trilogy Warrant is exercised. In addition, enforcement against a government counterparty is inherently uncertain given the defenses available to the U.S. government. The transactions contemplated by the letter of intent and the Strategic Investment may result in the U.S. government becoming one of the Company’s larger shareholders. The U.S. government’s interests in the Company may not be the same as those of other shareholders, and the presence of an additional large shareholder may dilute the voting power of existing or future shareholders. The contractual debt limitation may adversely impact the Company’s ability to raise capital. The existence of a significant U.S. government equity interest in the Company, and the U.S. government’s substantial additional powers with respect to the laws and regulations impacting the Company, may impact the Company's ability to pursue potential future strategic transactions that may be beneficial to shareholders.

We may be a “passive foreign investment company” infor our current and future periods,tax years, which may have adverse U.S. federal income tax consequences for U.S. Holders.

Added

U.S. Holders (as defined below under “Certain U.S. Federal Income Tax Considerations – U.S. Holders”) should be aware that we believe that we were a “passive foreign investment company” (a “PFIC”) within the meaning of Section 1297(a) of the Internal Revenue Code of 1986, as amended, for our most recently completed tax year, and based on current business plans and financial expectations, we may be a PFIC in the current tax year and future tax years. PFIC status depends on the composition of a company’s income and assets and the fair market of its assets (including goodwill) calculated on a yearly basis after the close of the taxable year, as well as on the application of complex statutory and regulatory rules that are subject to potentially varying or changing interpretations. There can be no assurance that we will not be treated as a PFIC for any taxable year.

U.S. Holders (as defined below under “Certain U.S. Federal Income Tax Considerations – U.S. Holders”) should be aware thatIf we believe we were not a passive foreign investment company (“PFIC”) for the tax years ending November 30, 2020 and 2021, but we believe we wereare a PFIC for theany tax yearsyear endingduring Novemberwhich 30,a 2018,U.S. 2019,Holder 2022,holds 2023Common andShares, 2024certain andadverse U.S. federal income tax consequences may beapply ato PFICsuch inU.S. future tax years.Holder.

In certain circumstances, the sum of the tax and the interest charge may exceed the total amount of proceeds realized on the disposition, or the amount of excess distribution received, by the U.S. Holder. Subject to certain limitations, these tax consequences may be altered if a U.S. Holder makes a timely and effective QEF Election or a Mark-to-Market Election (each as defined below under the heading “Certain U.S. Federal Income Taxation Considerations – Default PFIC Rules under Section 1291 of the Code”). A U.S. Holder who makes a QEF Election generally must report on a current basis its share of our net capital gain and ordinary earnings for any year in which we are a PFIC, whether or not we distribute any amountsamount to our shareholders. We will make available to U.S. Holders, upon their written request, information as to our status as a PFIC, as reasonably determined by us, and will provide to a U.S. Holder all information and documentation that a U.S. Holder making a QEF Election with respect to us that is required to obtain for U.S. federal income tax purposes in the event we are a PFIC. We may provide such information on our website. A U.S. Holder who makes the Mark-to-Market Election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the U.S. Holder’s tax basis therein. This paragraph is qualified in its entirety by the discussion below under the heading “Certain U.S. Federal Income TaxTaxation Considerations.” Each U.S. shareholderHolder should consult its own tax advisor regarding the PFIC rules and the U.S. federal income tax consequences of the acquisition, ownership, and disposition of their Common Shares.

Proposed legislation in the U.S. Congress, including changes in U.S. tax law may adversely impact the Companyus and the value of our Common Shares.

Reworded

Changes to U.S. tax laws (which changes may have retroactive application) could adversely affect the Companyus or holders of our Common Shares. In recent years, many changes to U.S. federal income tax laws have been proposed and made, and additional changes to U.S. federal income tax laws are likely to continue to occur in the future.

Reworded

The U.S. Congress is currently considering numerous items of legislation which may be enacted prospectively or with retroactive effect, which legislation could adversely impact the Company’sour financial performance and the value of our Common Shares. Additionally, U.S. states in which we operate or own assets may impose new or increased taxes. If enacted, most of the proposals would be effective for the current or later years. The proposed legislation remains subject to change, and its impact on the Companyus and purchasers of our Common Shares is uncertain.

Added

Changes in U.S. laws and policies regulating international trade may adversely impact the Company.

Added

The activities of the current administration in the United States may result in legislative and regulatory changes that could have a material adverse effect on the Company and its financial condition. In particular, there is uncertainty regarding U.S. tariffs and support for existing treaty and trade relationships, including with Canada. Although discussions continue between the United States and other countries, there remains significant uncertainty over whether tariffs or other restrictive trade measures or countermeasures will be implemented and, if so, the scope, impact and duration of any such measures. A trade war or new tariffs barriers may potentially lead to increases or decreases in revenues due to higher or lower metal prices, but the overall effect would depend on changes in demand, production strategies, and operational costs. Further, a trade war or new tariff barriers may potentially lead to increased costs and may result in uncertainty over mineral resources and reserve estimates in its technical reports. Additionally, due to worldwide economic uncertainty, the availability and cost of funds for development and other costs have become increasingly difficult, if not impossible, to project.

On October 6, 2025, President Trump issued a decision under Section 1106 of the Alaska National Interest Lands Conservation Act (“ANILCA”), granting the permits for the Ambler Access Project (or “Ambler Road”). The decision approved an appeal by the Alaska Industrial Development and Export Authority (“AIDEA”), a public corporation of the State of Alaska, to reverse the Biden Administration’s decision in June 2024 to select the “No Action Alternative” and terminate the previously issued right-of-way grant for the Ambler Road. President Trump directed relevant agencies to promptly reinstate, grant and finalize all necessary permits and authorizations with terms necessary to assure adequate and feasible access for economic and other purposes, such as mining and use of the road for industrial and commercial access. All federal right-of-way permits were subsequently issued and are currently in place.

On April 22, 2024, the Company announced that the United States Bureau of Land Management (“BLM”) had filed the final Supplemental Environmental Impact Statement (“SEIS”) for the AAP on its website. The final SEIS identifies “No Action” as the BLM’s preferred alternative. The proponent for the AAP is AIDEA which is a public corporation of the State of Alaska. AIDEA’s purpose is to promote, develop, and advance general prosperity and economic welfare of the people of Alaska. AIDEA strongly objected to both the process used by the BLM to reach a “No Build” decision and the effect of the decision which AIDEA believes illegally blocks access to statehood lands, minerals, and federally patented mining claims. On May 8, 2024, NANA announced its withdrawal from further involvement with the AAP and stated its intentions to not renew the surface access permit with AIDEA upon the permit’s expiry during the year.

Removed

On June 28, 2024, the BLM issued the Record of Decision confirming their selection of the No Action alternative and thus denied AIDEA’s application for a right-of-way grant (“ROW Grant”) across BLM-managed lands which terminated the BLM ROW Grant issued to AIDEA on January 5, 2021.

On January 20, 2025, President Trump signed the executive order “Unleashing Alaska’s Extraordinary Resource Potential,” which included a direction to various federal agencies to take steps to (i) “place a temporary moratorium on all activities and privileges granted pursuant” to the record of decision issued on June 28, 2024 “in order to review such record of decision in light of alleged legal deficiencies and for consideration of relevant public interests and, environmental impacts . . . and, as appropriate, conduct a new, comprehensive analysis of such deficiencies, interests, and environmental impacts;” and (ii) “reinstate the record of decision signed on July 23, 2020, by the Bureau of Land Management and United States Army Corps of Engineers entitled ‘Ambler Road Environmental Impact Statement Joint Record of Decision.’” The July 2020 record of decision approved the development of the northern or “Alternative A” route of the proposed 211-mile-long gravel private access road in the southern Brooks Range foothills to provide industrial access to the Ambler Mining District. Trilogy is monitoring the impact of the executive order.

Ambler Metals had $7.5 million of cash as at the fiscal year end on November 30, 2024. The main focus of this year’s budget is to support external and community affairs, maintain the State of Alaska mineral claims in good standing and the maintenance of physical assets.

Removed

The Company has approved a 2025 cash budget for corporate, head office, activities of approximately $3.1 million (2024 - $2.8 million).

Added

For the year ended November 30, 2025, we reported a net loss of $42.2 million (or $0.26 basic and diluted loss per common share) compared to a net loss of $8.6 million (or $0.05 basic and diluted loss per common share) in fiscal 2024. The increase in comprehensive loss in the current year was primarily driven by the initial recognition of a derivative liability and the corresponding expense of $8.1 million related to the U.S. government’s proposed collaboration agreement and the fair value adjustment of $22.6 million at the fiscal year end. Additionally, the increase in loss reflects higher salaries paid in cash during 2025, whereas in 2024 a significant portion of executive compensation as settled in common shares of the Company, as part of multi-year cash preservation effort. The increase in the current year loss was also attributable to higher professional fees, including legal and regulatory costs related to the Company’s preparation of base shelf prospectuses, the May ATM Program and the Nov ATM Program. These increases were partially offset by higher interest earned during the year.

Removed

For the year ended November 30, 2024, we reported a net loss of $8.6 million (or $0.05 basic and diluted loss per common share) compared to a net loss of $15.0 million (or $0.10 basic and diluted loss per common share) in fiscal 2023. The $6.4 million decrease in comprehensive loss in the current year, when compared to fiscal 2023, is due to the decrease in our share of losses of Ambler Metals of $5.2 million, overall decrease of $0.5 million in general and administrative expenses, professional fee and salaries and directors expense – stock-based compensation and partially offset by the increase in interest income of $0.6 million. The decrease in our share of losses of Ambler Metals of $5.2 million is mainly due to the decrease in corporate wages due to a reduction in staffing and a reduction in mineral property expenses due to a reduction in project activities which was partially offset by the increase in professional fees related to part-time contractors engaged to assist with management of Ambler Metals, along with consultants engaged in government and external affairs.

Added

For the fourth quarter of 2025, we incurred a net loss of $34.7 million compared to a net loss of $1.6 million in the fourth quarter of 2024. The increase in net loss is primarily driven by our share of loss from the equity investment in Ambler Metals and the loss on the derivative related to the U.S. government’s proposed strategic investment for shares and warrants carried at fair market value. The increase in comprehensive loss in the current year also reflects higher regulatory expenses and legal fees related to the Company’s preparation of base shelf prospectuses and at-the-market programs and the payment of executive compensation in cash instead of settling the compensation in common shares of the Company.

Removed

For the fourth quarter of 2024, there was a $1.4 million reduction in expenses compared to the fourth quarter of 2023. When comparing the fourth quarter of 2024 with the fourth quarter of 2023, professional fees increased by $0.2 million due to additional costs related to our Bornite preliminary economic assessment reports in the fourth quarter of 2024. The decrease in our share of losses of Ambler Metals of $1.2 million is mainly due to the decrease in mineral property expenses over the comparative quarter in the prior year were from a reduction in activities both at the project level and at the AAP.

The decrease in comprehensive loss in the third quarter of 2024 compared to the same quarter in 2023 is primarily due to the decrease in our share of loss of Ambler Metals. The decrease of our share of losses of Ambler Metals is mainly due to the decrease in corporate wages and in mineral property expenses partially offset from the increase in professional fees. The primary drivers in decrease in mineral property expenses over the comparative quarter in the prior year were from a reduction in activities both at the project level and at the AAP.

Removed

The decrease of our share of losses of Ambler Metals is mainly due to the decrease corporate wages and in mineral property expenses. The primary drivers in decrease in mineral property expenses over the comparative quarter in the prior year were from the decrease in project support costs and cost at the AAP.

Added

During the year ended November 30, 2025, we spent $3.2 million in operating activities, spent $1.0 million in investing activities, and raised $30.0 million in financing activities. Operating expenditures were driven primarily by corporate salaries, professional fees to complete the Bornite PEA, and the preparation of base shelf prospectuses, at-the-market programs, including regulatory filing fees with the U.S. and Canadian securities commissions. In addition, the Company contributed $1.0 million for our share of funding to Ambler Metals. These cash outflows were offset by $30.0 million in proceeds from financing activities, primarily from the May ATM Program and exercise of stock options.

Removed

We expended $1.8 million on operating activities during the 2024 fiscal year with the majority of cash spent on corporate salaries, professional fees related to our annual regulatory filings, annual insurance renewal, annual fees paid to the Toronto Stock Exchange and the NYSE American Exchange and with the American and Canadian securities commissions.

Fair value accounting

Added

Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the significance of the inputs used in making the measurement. The three levels of the fair value hierarchy are as follows:

Added

Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Added

Level 2 – Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

Removed

Financial instruments

Reworded

OurThe Company’s financial instruments consist of cash,cash and cash equivalents, accounts receivable, deposits, and accounts payable and accrued liabilities. The fair value of the Company’s financial instruments approximates their carrying value due to the short-term nature of their maturity. OurThe Company’s financial instruments initially measured at fair value and then held at amortized cost include cash,cash and cash equivalents, accounts receivable, deposits, and accounts payable and accrued liabilities. The majority of the Company’s cash and cash equivalents is held at two large Canadian financial institutions and is largely uninsured as at November 30, 2025.

Added

The derivative liability is carried at fair value on a recurring basis. The fair value of the derivative liability is valued on the basis of Level 3 inputs. The estimated fair value is based on the Company’s common stock price of $4.28 at November 30, 2025 ($2.09 on October 7, 2025), volatility of 79%, a risk-free rate of 3.53% and management’s estimate of the equal probability of completion and non-completion of the Ambler Access Project, which is beyond the control of the Company. A 10% change in the Company’s stock price affects the gain or loss on the derivative liability by approximately $4.8 million at November 30, 2025. A 10% change in management’s estimate of the likelihood of completion affects the gain or loss on the derivative liability by approximately $1.3 million at November 30, 2025.

(a) Currency risk

Removed

Currency risk is the risk of a fluctuation in financial asset and liability settlement amounts due to a change in foreign exchange rates. The Company operates in the United States and Canada. The Company’s exposure to currency risk at November 30, 2024 is limited to Canadian dollar balances consisting of cash of CDN$116,000, accounts receivable of CDN$23,000 and certain trade payables and accrued personnel costs CDN$548,000. Based on a 10% change in the US-Canadian exchange rate, assuming all other variables remain constant, the Company’s net loss would change by approximately $29,000.

Removed

(b) Credit risk

Removed

Credit risk is the risk of an unexpected loss if a customer or third party to a financial instrument fails to meet its contractual obligations. The Company holds cash with Canadian chartered financial institutions. The Company’s only significant exposure to credit risk is equal to the balance of cash as recorded in the financial statements. The majority of the Company’s cash held at November 30, 2024 is uninsured. The Company does not consider any of its financial assets to be impaired as of November 30, 2024.

Removed

(c) Liquidity risk

Removed

Liquidity risk is the risk that we will encounter difficulties raising funds to meet our financial obligations as they fall due. We are in the exploration stage and do not have cash inflows from operations; therefore, we manage liquidity risk through the management of our capital structure and financial leverage. Future sources of liquidity may arise from equity financing, debt financing, convertible debt, or other means.

The United States Department of War’s ownership interest may create additional governance, regulatory and geopolitical considerations for the Company.

Added

The DOW ownership interest and Board observer right may result in increased governmental engagement with, or perceived influence over, the Company.

ExtensionClosing of BindingStrategic LetterEquity ofInvestment Intent withfrom the United States Department of War

Added

On August 28, 2026, the Company entered into the Investment Agreement (the “Investment Agreement”) with the United States Department of War (the “DOW”), relating to the DOW’s strategic investment in the Company (the “Strategic Investment”). On September 11, 2026, the Company completed the Strategic Investment by the DOW, pursuant to the Binding Letter of Intent entered on October 6, 2025. At closing, the Company issued 8,215,570 units to the DOW at a price of $2.17 per unit for gross proceeds of approximately $17.8 million. Each unit consisted of one common share and three-quarters of one warrant, resulting in the issuance of warrants to acquire up to 6,161,678 additional common shares at an exercise price of $0.01 per share. The warrants have a ten-year term and become exercisable upon the earlier of the completion of Phase 1 of the Ambler Access Project, the achievement of certain specified usage milestones for the Ambler Access Project and a change of control of the Company.

Added

The Company received gross proceeds of approximately $17.8 million upon closing of the Strategic Investment. The proceeds are specifically designated to fund an additional cash capital contribution to Ambler Metals and, therefore, do not represent additional liquidity available to fund the Company’s general corporate activities. South32 will make a corresponding contribution on a pro-rata basis, such that the Company’s 50% ownership interest in Ambler Metals will remain unchanged.

Added

In connection with closing, the Company, through its wholly-owned subsidiary Trilogy Metals US, and the DOW, among other parties, also entered into a Cooperation Agreement (the “Cooperation Agreement”, and together with the Investment Agreement and other ancillary agreements, the “DOW Transaction Documents”) pursuant to which the DOW is entitled to (i) designate one independent third-party nominee for appointment to the Company’s Board of Directors, and (ii) appoint a representative to attend meetings of the Company’s Board of Directors in an observer capacity.

Added

The closing also resulted in the settlement of the derivative liability previously recognized in connection with the Company’s obligation to issue common shares and warrants to the DOW. Upon settlement, the Company recognized a gain of approximately $3.9 million, representing the change in the derivative liability through the closing date. The derivative liability was extinguished upon issuance of the underlying securities, and the applicable amounts were reclassified to share capital and contributed surplus. As a result, subsequent changes in the value of the Company’s common shares will no longer result in fair value adjustments associated with this derivative liability. The gain recognized on settlement is non-cash in nature and therefore does not affect the Company’s cash flows.

Added

The Strategic Investment represents a significant source of funding for the Company’s investment in Ambler Metals while maintaining the Company’s 50% ownership interest in the joint venture. Future exercise of the warrants could result in future dilution of share capital, although such exercise is subject to the specified conditions described above.

Removed

On May 30, 2026, the Company, South32, Ambler Metals and the United States Department of War agreed to a second amendment to the binding letter of intent (“LOI”) dated October 6, 2025. The second amendment extends the deadline for the completion of the transaction from May 31, 2026 to July 31, 2026.

The program includes drilling and technical work to support mine planning, permitting, and future development decisions at the Arctic Project, as well as site readiness activities at Bornite and regional exploration target assessments.

Added

In line with the June 9, 2026 press release, exploration was undertaken during summer 2026. Expenses were incurred over the summer to advance planned exploration, permitting, engineering, environmental, and site activities while seasonal field conditions allowed the work to proceed.

The increase in net loss was primarily driven by two non-cash items: i) the mark-to-market fair value adjustment for the derivative liability related to our obligation to issue shares and warrants to the U.S. Department of War; and ii) stock-based compensation expense related to our annual grant with higher Black-Scholes values in the current year compared to the prior year.year; Theand netii) loss was also impacted by an increase inincreased activity related to budgeted exploration activities at Ambler Metals which resulted in a larger amount for our share of loss on equity investment and an increase in personnel costs due to the addition of senior staff.
