**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

**1. THE COMPANY**

i-80 Gold Corp ("i-80 Gold" or the "Company"), is a Nevada-focused, growth-oriented gold and silver mining company engaged in the exploration and extraction of gold and silver. The Company's principal assets include the Granite Creek property, Ruby Hill property, Cove property, and the Lone Tree property which hosts a carbon-in-leach and an autoclave processing plant that is currently undergoing a refurbishment. Each property is wholly-owned by the Company.

The Company was incorporated on November 10, 2020, in the province of British Columbia, Canada. The Company's common shares are listed on the New York Stock Exchange ("NYSE American") under the trading symbol IAUX and on the Toronto Stock Exchange ("TSX") under the trading symbol IAU. The Company's head office is located in Reno, Nevada, United States and its executive office is located in Toronto, Ontario, Canada.

**2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

&nbsp;&nbsp;&nbsp;&nbsp;**(a)Risks and uncertainties and liquidity**

As a mining company, the Company's revenue, profitability and future rate of growth are substantially dependent on prevailing metal prices, primarily for gold and silver. The prices of these metals are volatile and there can be no assurance that commodity prices will not be subject to wide fluctuations in the future. A substantial or extended decline in commodity prices could have a material adverse effect on the Company's balance sheet, results of operations, cash flows, access to capital and the quantities of mineralized material. The carrying value of the Company's property, plant and equipment, net, inventories, and certain derivative instruments are particularly sensitive to the outlook for commodity prices. A decline in the Company's price outlook from current levels could result in material impairment charges related to these assets.

In addition to changes in commodity prices, other factors such as changes in mine plans, increases in costs, geotechnical failures, changes in social, environmental or regulatory requirements and impacts of global events could result in material impairment charges related to these assets.

These interim unaudited Condensed Consolidated Financial Statements ("Financial Statements") have been prepared by management on a going concern basis. The going concern basis of presentation assumes the Company will continue in operation for the foreseeable future and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business.

As disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025, conditions including a working capital deficit, operating losses and an expectation of future losses raised substantial doubt about the Company's ability to continue as a going concern. During the three months ended March 31, 2026, the Company completed the recapitalization of its capital structure through the completion of a gold prepay agreement and net smelter return royalty agreement, and the issuance of convertible debentures, the proceeds of which were used to repay its outstanding indebtedness, with the exception of the Silver Purchase Agreement which remains outstanding. As of March 31, 2026, the Company has $513.5 million of cash on hand, which it believes is sufficient to meet the Company's obligations as they became due within one year after the issuance of these financial statements. The Company has assessed the relevant conditions and events and has concluded that substantial doubt about the Company's ability to continue as a going concern no longer exists.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)Basis of presentation**

The Financial Statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and are unaudited. While information and note disclosures normally included in annual financial statements and prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations, the Company believes that the information and disclosures included in the Financial Statements are adequate and not misleading. Therefore, this information should be read in conjunction with the audited consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 filed on February 19, 2026. Except as noted below, there have been no material changes in the footnotes from those accompanying the audited consolidated financial statements contained in the Company's Form 10-K for the year ended December 31, 2025. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. All such adjustments are, in the opinion of management, of a normal recurring nature. The results for the three months ended March 31, 2026, are not necessarily indicative of the results that may be expected for the year ending December 31, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;**(c)Recently Issued Accounting Standards**

***Disaggregation of Income Statement Expenses***

In November 2024, ASU 2024-03 was issued, requiring additional disclosures in the notes to the financial statements on the nature of certain expense captions presented on the face of the Consolidated Statement of Operations. The new guidance is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impacts of the guidance on its consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;*(i)2026 Convertible Debentures*

On March 23, 2026, the Company closed an offering for gross proceeds of $287.5 million principal amount of unsecured senior convertible debentures (the "2026 Convertible Debentures"). The Company received net proceeds of $274.5 million after debt issuance costs of $13.0 million. The 2026 Convertible Debentures bear interest at a rate of 3.75% per annum, payable semi-annually in arrears in cash on April 15 and October 15 of each year, commencing October 15, 2026. The 2026 Convertible Debentures mature on April 15, 2031, unless earlier converted, redeemed, or repurchased.

The 2026 Convertible Debentures are convertible into common shares of the Company at any time prior to maturity at a conversion rate of 519.4805 Common Shares per $1,000 principal amount, equivalent to an initial conversion price of approximately $1.93 per common share, subject to certain anti-dilution adjustments.

The 2026 Convertible Debentures are not redeemable by the Company prior to April 20, 2029. On or after April 20, 2029, the Company may redeem the 2026 Convertible Debentures, in whole or in part, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the redemption date, provided that the closing sale price of the Company's common shares has exceeded 130% of the conversion price then in effect for at least 20 trading days during a period of 30 consecutive trading days.

In addition, the Company may redeem the 2026 Convertible Debentures in whole (but not in part), at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest, if the Company becomes obligated to pay additional amounts as a result of certain changes in Canadian tax law or regulations occurring on or after March 18, 2026.

If a fundamental change occurs including a change of control event, the Company is required to offer to repurchase the 2026 Convertible Debentures for cash at a purchase price equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the repurchase date.

The Company accounts for the 2026 Convertible Debentures as a single financial liability measured at amortized cost. Interest expense was calculated by applying the effective interest rate of 4.72% to the carrying amount of the debt liability. Interest accretion is included in interest expense.

The 2026 Convertible Debentures are senior unsecured obligations of the Company as the 2026 Convertible Debentures are not guaranteed by any subsidiary. The indenture does not contain any financial maintenance covenants.

As of March 31, 2026, the outstanding principal amount of the 2026 Convertible Debentures was $287.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;*(ii)2026 Gold Prepay*

On March 16, 2026, the Company entered into a gold prepayment facility and forward gold arrangements (the "2026 Gold Prepay") with National Bank of Canada ("NBC") and Macquarie Bank Limited ("Macquarie"). Under the 2026 Gold Prepay, the Company received aggregate gross proceeds of $150.0 million and net proceeds of $144.1 million, net of debt issuance costs of $5.9 million. In exchange, the Company is obligated to deliver an aggregate of 39,978 ounces of gold, with monthly deliveries scheduled from January 2028 through June 2030.

The Company has an accordion feature which provides an additional $100 million for a 24-month period from closing, subject to customary conditions and lender approval.

The Company accounts for each counterparty arrangement within the 2026 Gold Prepay as a hybrid instrument consisting of a debt host contract and a bifurcated embedded derivative. The host contract is accounted for as a financial liability and is measured at amortized cost. The arrangement contains a gold-indexed pricing feature that is bifurcated and accounted for as an embedded derivative measured at fair value each reporting period (Note 4 and Note 19).

Interest expense was calculated by applying the effective interest rate of 13.5% to the carrying amount of the debt liability. Interest accretion is included in interest expense.

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

The 2026 Gold Prepay is secured by a first-ranking security interest over substantially all of the assets of the Company and its material subsidiaries, subject to permitted liens and customary carve-outs. The supplementary terms agreement ('STA') includes customary financial covenants and events of default.

&nbsp;&nbsp;&nbsp;&nbsp;*(iii)Silver Purchase Agreement*

On December 13, 2021, in exchange for $30.0 million, the Company entered into a silver purchase and sale agreement with Orion (the "Silver Purchase Agreement"). Under the Silver Purchase Agreement, commencing April 30, 2022, the Company will deliver to Orion 100% of the silver production from the Granite Creek and Ruby Hill projects until the delivery of 1.2 million ounces of silver, after which the delivery will be reduced to 50% until the delivery of an aggregate of 2.5 million ounces of silver, after which the delivery will be reduced to 10% of the silver production solely from Ruby Hill Project. Orion will pay the Company an ongoing cash purchase price equal to 20% of the prevailing silver price. Until the delivery of an aggregate of 1.2 million ounces of silver, the Company is required to deliver the following minimum amounts of silver ("the Annual Minimum Delivery Amount") in each calendar year: (i) in 2022, 300,000 ounces, (ii) in 2023, 400,000 ounces, (iii) in 2024, 400,000 ounces, and (iv) in 2025, 100,000 ounces. In the event that in a calendar year the amount of silver delivered under the Silver Purchase Agreement is less than the Annual Minimum Delivery Amount, the Company shall make up such difference (the "Shortfall Amount") by delivering on or before the fifteenth day of the month immediately following such calendar year (the "Delivery Deadline"). At the Company's sole option, the obligation to make up the Shortfall Amount to Orion may be satisfied by the delivery of refined gold instead of refined silver, at a ratio of 1/75th ounce of refined gold for each ounce of refined silver. The Silver Purchase Agreement was funded April 2022.

The Silver Purchase Agreement is recognized as a financial liability at amortized cost and it contains two embedded derivatives as further described in Note 7 (ii) and Note 19 of these Financial Statements. Interest expense is calculated by applying the effective interest rate to the financial liability. As of March 31, 2026, the effective interest rate was 21.8% (December 31, 2025 - 21.9%). Interest accretion is included in interest expense.

During the three months ended March 31, 2026, the Company settled 94,158 ounces of silver in satisfaction of the remaining 2025 Minimum Annual Delivery Amount. As of March 31, 2026, the Company has delivered an aggregate of 1.2 million ounces of silver under the Silver Purchase Agreement, satisfying all Annual Minimum Delivery Amounts required through 2025, with no remaining minimum delivery obligations outstanding.

The obligations under the Silver Purchase Agreement are secured obligations of the Company and its wholly-owned subsidiaries Ruby Hill Mining Company LLC, and Osgood Mining Company LLC, and secured against the Ruby Hill project in Eureka County, Nevada and the Granite Creek project in Humboldt County, Nevada.

&nbsp;&nbsp;&nbsp;&nbsp;*(iv)2023 Convertible Debentures*

On February 22, 2023, the Company closed a private placement offering of $65 million principal amount of secured convertible debentures (the "2023 Convertible Debentures") of the Company. The 2023 Convertible Debentures bore interest at a fixed rate of 8.0% per annum and had a maturity date of February 22, 2027. Outstanding amounts under the 2023 Convertible Debentures were convertible into common shares of the Company at any time prior to maturity at the option of the applicable respective lender (a) in the case of the outstanding principal, $3.38 per common share, and (b) in the case of accrued and unpaid interest, subject to TSX approval, at the market price of the common shares at time of the conversion of such interest. The 2023 Convertible Debentures were redeemed in full during the first quarter of 2026, as further described below.

On February 28, 2025, the Company completed certain amendments to its 2023 Convertible Debentures. The amendments provided for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the conversion price applicable to the debenture holder's right to elect to convert outstanding and accrued interest on the 2023 Convertible Debentures is equal to the volume weighted average price of i-80 Gold's common shares on the TSX during the five trading days immediately preceding the date of the debenture holder's election notice, less a discount of 15%, converted into US dollars at the Bank of Canada rate on such date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the conversion price applicable to the Company's right to elect to convert outstanding and accrued interest on the 2023 Convertible Debentures is equal to the greater of (x) 85% of the average closing price of the i-80 Gold common shares as measured in US dollars on the NYSE American during the 10 business days immediately preceding the date of the Company's election notice, and (y) the volume weighted average price of i-80 Gold common shares on the TSX during the five trading days immediately preceding the date of the Company's election notice, less a discount of 15%, converted into US dollars at the Bank of Canada rate on such date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• that the Company's right to grant security against the Cove Project would rank subordinate to the security granted to the debenture holders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Company with a redemption right in respect of all of the outstanding 2023 Convertible Debentures which allows the Company to redeem, in its sole discretion, all of the outstanding 2023 Convertible Debentures for cash at a 104% premium of the outstanding principal and the accrued interest up to the redemption date.

Management determined that the modification to the agreement was non-substantial and accordingly, the Company accounted for the modification as an adjustment to the financial liability.

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

During the first quarter of 2026, the Company exercised its redemption right and redeemed all of the outstanding 2023 Convertible Debentures at a 104% premium of the outstanding principal plus accrued interest up to the redemption date. The principal amount of $65.0 million, together with the 4% mandatory redemption premium of $2.6 million, was repaid in cash. Accrued interest of $18.0 million, together with the 4% mandatory redemption premium of $0.7 million, totalling $18.7 million, was settled through the issuance of 8.1 million common shares with a fair value of $13.4 million (Note 8) and a cash payment of $5.3 million. Total cash consideration paid amounted to $72.9 million. Upon extinguishment, the Company derecognized the carrying amount of the debt liability and recorded a loss on extinguishment of debt of $4.4 million. The loss represents the excess of the repayment amount of the debt over its carrying amount and is included in loss on loan extinguishment.

The 2023 Convertible Debentures contained a conversion feature, a change of control feature, and a forced conversion feature that were considered embedded derivatives by the Company and measured at fair value (Note 19). The conversion feature, change of control feature, and a forced conversion feature were classified as financial liabilities and not separated from the host liability component. The conversion feature and forced conversion feature were considered to be indexed to the Company's shares. The mandatory redemption right was considered to be an embedded derivative by the Company, classified as financial liability and not separated from the host liability component.

Interest expense was calculated by applying the effective interest rate of 9.4% to the host liability component up to the date of redemption. Interest accretion is included in interest expense.

&nbsp;&nbsp;&nbsp;&nbsp;*(v)Orion Convertible Loan*

On December 13, 2021, the Company entered into a Convertible Credit Agreement with OMF Fund III (F) Ltd., an affiliate of Orion to borrow $50 million (the "Orion Convertible Loan"). The Orion Convertible Loan bore interest at a rate of 8.0% annually and had a maturity date of June 30, 2026. The Orion Convertible Loan was repaid in full during the first quarter of 2026.

On January 15, 2025, the Company entered into an Amended and Restated Orion Convertible Loan Agreement. Pursuant to the amendment, the maturity date was extended from December 13, 2025, to June 30, 2026, and certain security was put in place to secure the Company's obligations under the Orion Convertible Loan. Additional security against the Company's Ruby Hill and Granite Creek projects was put in place as of March 31, 2025. In connection with the amendment the Company issued to Orion 5.0 million common share purchase warrants (Note 7) and entered into an offtake agreement with Orion. The offtake agreement will commence once the current offtake agreement expires at the end of December 2028. Management determined that the modification to the agreement was non-substantial and accordingly, the Company accounted for the modification as an adjustment to the financial liability.

During the first quarter of 2026, the Company repaid the Orion Convertible Loan in full, including the outstanding principal of $50.0 million and accrued interest of $20.4 million. The Orion Convertible Loan was extinguished through a cash payment of $69.7 million and the issuance of 3.0 million common shares with a fair value of $5.3 million (net $5.2 million) (Note 8), for total consideration of $75.0 million. Upon early repayment, the Company derecognized the carrying amount of the debt host liability and the related derivative liabilities and recorded a loss on extinguishment of debt of $1.6 million. The loss represents the excess of the repayment amount over the aggregate carrying amount of the host debt and the related derivative liabilities and is included in loss on loan extinguishment. As at March 31, 2026, there are no amounts outstanding under the Orion Convertible Loan.

The Orion Convertible Loan contained a change of control feature, a conversion feature, and a forced conversion feature that were considered embedded derivatives by the Company. The change of control feature and conversion feature were classified as derivative financial liabilities measured at fair value (Note 19). The forced conversion feature was not separated from the host contract as it was considered to be indexed to the Company's shares. The initial fair value of the convertible loan was determined using a market interest rate for an equivalent non-convertible loan at the issue date. The liability was subsequently recognized on an amortized cost basis until extinguished.

Interest expense was calculated by applying the effective interest rate of 16.72% to the host liability component up to the date of repayment. Interest accretion is included in interest expense.

&nbsp;&nbsp;&nbsp;&nbsp;*(vi)Orion Gold Prepay*

On December 13, 2021, the Company entered into a gold prepay agreement with Orion (the "Orion Gold Prepay"). In April 2022, the Gold Prepay was amended to adjust the quantity of the quarterly deliveries of gold, but not the aggregate amount of gold, to be delivered by the Company to Orion over the term of the Orion Gold Prepay. Under the terms of the amended Orion Gold Prepay, in exchange for $41.9 million, the Company was required to deliver to Orion 3,100 ounces of gold for the quarter ending June 30, 2022, and thereafter, 2,100 ounces of gold per calendar quarter until September 30, 2025, for aggregate deliveries of 30,400 ounces of gold.

On September 20, 2023, the Company entered into an A&R Gold Prepay with Orion pursuant to which the Company received aggregate gross proceeds of $20.0 million (the "2023 Gold Prepay Accordion") structured as an additional accordion under the existing Orion Gold Prepay. The 2023 Gold Prepay Accordion will be repaid through the delivery by the Company to Orion of 13,333 ounces of gold over a period of 12 quarters, being 1,110 ounces of gold per quarter over the delivery period with the first delivery being 1,123 ounces of gold. The first delivery will occur on March 31, 2024, and the last delivery will occur on December 31, 2026.

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

During the first quarter of 2026, the Company fully settled the outstanding deliveries of 4,440 ounces of gold remaining under the Orion Gold Prepay through a cash payment of $22.4 million. Upon extinguishment, the Company derecognized the carrying amount of the debt host liability and the related derivative liability and recorded a loss on extinguishment of debt of $1.1 million. The loss represents the excess of the repayment amount over the aggregate carrying amount of the host debt and the related derivative liability and is included in loss on loan extinguishment.

The Orion Gold Prepay was recognized as a financial liability measured at amortized cost and contained an embedded derivative in relation to the embedded gold price within the agreement that was bifurcated and measured at fair value each reporting period through the date of extinguishment (Note 7 and Note 19). Interest expense was calculated by applying the effective interest rate of 29.1% to the carrying amount of the debt liability up to the date of repayment. Interest accretion is included in interest expense.

&nbsp;&nbsp;&nbsp;&nbsp;*(vii)Sprott Convertible Loan*

On December 10, 2021, the Company entered into a Convertible Credit Agreement with a fund managed by Sprott Asset Management USA, Inc. and a fund managed by CNL Strategic Asset Management, LLC ("Sprott") to borrow $10 million (the "Sprott Convertible Loan"). The Sprott Convertible Loan bore interest at a rate of 8.0% annually and matured on December 9, 2025. At maturity, the Company repaid the outstanding balance.

The Sprott Convertible Loan contained a change of control feature, a conversion feature, and a forced conversion feature that were considered embedded derivatives by the Company. The change of control feature and conversion feature were classified as derivative financial liabilities measured at fair value (Note 19). The forced conversion feature was not separated from the host contract as it was considered to be indexed to the Company's shares. The initial fair value of the convertible loan was determined using a market interest rate for an equivalent non-convertible loan at the issue date. The liability was subsequently recognized on an amortized cost basis until maturity of the loan.

Interest expense was calculated by applying the effective interest rate of 16.10% to the host liability component. Interest accretion is included in interest expense.

&nbsp;&nbsp;&nbsp;&nbsp;*(viii)2025 Gold Prepay and Silver Purchase Agreement* 

On March 31, 2025, the Company entered into a Gold Prepay and Silver Purchase arrangement (the "2025 Gold Prepay and Silver Purchase Agreement") with NBC under which NBC purchased 6,864 ounces of gold and 345,549 ounces of silver from the Company for delivery to NBC by September 30, 2025 or earlier, upon an infusion of capital in line with the recapitalization plan. The proceeds of this prepay arrangement were used to satisfy the outstanding gold and silver deliveries due to Orion under its respective Gold Prepay Agreement and Silver Purchase Agreement. 2025 Gold Prepay and Silver Purchase Agreement was funded on April 1, 2025 for total proceeds of $31.0 million. On May 16, 2025, the Company repaid the full outstanding balance under the 2025 Gold Prepay and Silver Purchase Agreement, consisting of principal of $31.0 million and financing expense of $1.3 million.

The 2025 Gold Prepay and Silver Purchase Agreement contained an early termination make-whole provision and a mandatory prepayment provision, that were considered embedded derivatives by the Company and measured at fair value. The early termination make-whole provision and mandatory prepayment provision were classified as financial liabilities and not separated from the host liability component as they were deemed to be closely related.

&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>NSR Royalty</u>

On March 16, 2026, the Company entered into a net smelter return royalty financing arrangement with Franco-Nevada U.S. Corporation ("Franco-Nevada")(the "NSR Royalty"), granting a perpetual royalty on production from the Company's properties, including Granite Creek, Cove, the Ruby Hill Complex and Lone Tree. Gross proceeds were $250.0 million, of which $225.0 million was received at closing. Of the $225 million amount received, $25 million is required to be allocated to the advancement of technical and permitting work on the Mineral Point project. An additional $25.0 million is expected to be made available to advance Mineral Point, contingent upon satisfaction of specified project expenditure conditions related to the Mineral Point project.

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

The royalty rate is 1.5% of net smelter returns through December 31, 2030, increasing to 3.0% thereafter. The royalty is payable monthly in cash or in-kind as refined gold or silver at Franco-Nevada's election.

The royalty obligation was classified as a financial liability. Upon initial recognition, the Company elected the fair value option and, accordingly, measures the obligation at fair value at each reporting date. As of March 31, 2026, the current portion of the NSR Royalty liability was $3.2 million (December 31, 2025 - nil). Finance fees of $6.4 million related to the NSR royalty have been recognized in other expense (Note 12).

&nbsp;&nbsp;&nbsp;&nbsp;(ii)<u>Silver Purchase Agreement embedded derivative</u>

The financial liability represents the embedded derivative in relation to the silver price included in the Silver Purchase Agreement (Note 6 and Note 19). The Company recognizes the embedded derivative at fair value with any changes in fair value recorded in other income or other expense (Note 12). As of March 31, 2026, the current portion of the Silver Purchase Agreement embedded derivative liability was nil (December 31, 2025 - $2.7 million).

| Total warrant liability |  |  |  |  | $**23714** | $24117 |

---

The warrants are considered derivatives because their exercise price is in C$ whereas the Company's functional currency is in USD. Accordingly, the Company recognizes the warrants as liabilities at fair value with changes in fair value recorded in other income or other expense (Note 12). The current portion of the liability is $0.3 million at March 31, 2026 (December 31, 2025 - $0.4 million).

The fair value of the warrants, excluding warrants issued in connection with the May 2024 brokered placement, were calculated using the Black-Scholes option pricing model with the following assumptions:

---

| | | |
|:---|:---|:---|
| | **March 31, 2026** | December 31, 2025 |
| Risk-free rate | **2.4% to 2.9%** | 2.3% to 2.7% |
| Expected volatility | **66% to 110%** | 64% to 104% |

---

&nbsp;&nbsp;&nbsp;&nbsp;(iv)<u>Share-based payment liability</u>

The Company recognized a share-based payment liability related to its restricted share units (RSUs) that are accounted for as liability-classified awards. The current portion of the share-based payment liability is $1.5 million at March 31, 2026 (December 31, 2025 - $1.9 million).

&nbsp;&nbsp;&nbsp;&nbsp;(v)<u>Lease liability</u>

Lease liabilities relate primarily to equipment and office rentals. The weighted average remaining lease life is 2 years and the weighted average discount rate is 8.43%. Undiscounted remaining payments are $2.5 million for 2026, $2.4 million for 2027-2030 and $0.1 million thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;(vi)<u>Orion Gold Prepay embedded derivative</u>

The financial liability represented the embedded derivative related to the gold-indexed pricing feature within the Orion Gold Prepay (Note 6 and Note 19). The Company recognized the embedded derivative at fair value, with any changes in fair value recorded in other income or other expense (Note 12). Upon settlement of the Orion Gold Prepay during the first quarter of 2026, the related embedded derivative liability was derecognized.

&nbsp;&nbsp;&nbsp;&nbsp;(vii)<u>Conversion and change of control right</u>

The Orion Convertible Loan contained a change of control feature, a conversion feature, and a forced conversion feature that were classified as derivative financial liabilities measured at fair value (Note 19). The forced conversion feature was not separated from the host contract as it is considered to be indexed to the Company's shares. Changes in the fair value of the embedded derivative liabilities were recognized in other income or other expense (Note 12).

During the first quarter of 2026, the Orion Convertible Loan was repaid in full and the related embedded derivative liabilities were derecognized upon extinguishment of the loan.

&nbsp;&nbsp;&nbsp;&nbsp;(i)On January 31, 2025, the Company closed a prospectus offering of 28.2 million common shares of the Company at a price of C$0.80 per share for aggregate gross proceeds of $15.6 million (C$22.6 million). On February 28, 2025, in connection with the prospectus offering, the Company closed a concurrent private placement of 1.0 million common shares to certain directors and officers of the Company at a price of C$0.80 per share for aggregate gross proceeds of $0.6 million (C$0.8 million).

&nbsp;&nbsp;&nbsp;&nbsp;(ii)During the three months ended March 31, 2025, the Company issued 4.3 million common shares under the at-the-market equity program ("ATM Program") for total gross proceeds of $2.5 million. The ATM Program expired on March 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)On May 16, 2025, the Company closed a bought deal public offering of 345.8 million units of the Company at a price of $0.50 per unit for aggregate gross proceeds of $172.9 million and net proceeds of $162.5 million. In addition to the bought deal public offering, the Company closed a private placement of 25.2 million units to certain directors, officers and other shareholders of the Company at a price of $0.50 per unit for aggregate gross proceeds of $12.6 million and net proceeds of $12.5 million. Each unit for both offerings is comprised of one common share and one-half of one common share purchase warrant. Each warrant entitles the holder to purchase one common share at a price of $0.70 until November 16, 2027. The total number of warrants issued were 185.5 million.

The Company has assessed the warrants to meet the requirements to be recorded as equity. The net proceeds from the bought deal offering and the private placement were allocated to the warrants in the amount of $10.5 million and $164.9 million allocated to share capital based upon the relative fair values of the shares and warrants issued.

During the three months ended March 31, 2026, 13.6 million warrants were exercised at an exercise price of $0.70 per share, resulting in the issuance of common shares of the Company for cash proceeds of $9.5 million and a reclassification of $0.8 million from additional paid-in-capital.

&nbsp;&nbsp;&nbsp;&nbsp;(iv)In connection with the 2023 Convertible Debenture redemption the Company issued 8.1 million common shares with a fair value of $13.4 million.

&nbsp;&nbsp;&nbsp;&nbsp;(v)In connection with the Orion Convertible Loan repayment the Company issued 3.0 million common shares with a fair value of $5.3 million and net proceeds of $5.2 million.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)Share-based payments**

The Company has a share incentive plan (the "Plan") which is restricted to directors, officers, key employees and consultants of the Company. Share incentive awards include stock options, RSUs, deferred share units ("DSU"), and performance share units ("PSU"). The number of common shares issuable under the Plan is limited to 10% in the aggregate of the number of issued and outstanding common shares of the Company at the date of the grant of the award.

The following table summarizes share-based payment expense included in the statement of loss:

---

| | | |
|:---|:---|:---|
| | **Three months ended<br>March 31,** | **Three months ended<br>March 31,** |

| Deferred share units | **185** | 142 |
| Performance share units | **254** |  |
| Stock options | **5** | 49 |
| Total | $**3059** | $692 |

---

Of the total share-based payment expense, $2.4 million was recorded in general and administrative expenses and $0.6 million in cost of sales (2025 - $0.7 million and nil, respectively).

During the three months ended March 31, 2026, the Company granted 2,791,485 RSUs, 1,860,752 PSUs and 188,189 DSUs to its officers, employees and directors, and issued 1,132,127 common shares upon vesting of RSUs.

The PSUs have a performance multiplier from 0% to 200% of the number of units granted based on the Company's total shareholder return relative to the performance of an exchange traded fund. The Company used a Monte-Carlo simulation and determined a weighted average grant date fair value of $2.26 per unit granted.

**9. BASIC AND DILUTED LOSS PER SHARE**

Basic loss per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted loss per share is based on the assumption that potential dilutive shares have been issued. The calculation of basic and diluted loss per share is as follows:

---

| | | |
|:---|:---|:---|
| | **Three months ended<br>March 31,** | **Three months ended<br>March 31,** |
| | **2026** | 2025 |
| Net loss | $**(78601)** | $(41205) |
| Basic and diluted weighted average shares outstanding | **837103078** | 431341371 |
| Basic and diluted loss per share | $**(0.09)** | $(0.10) |

---

Convertible debentures of 149,350,644, stock options of 8,013,202, PSUs of 11,332,188, DSUs of 1,811,481, and warrants of 204,477,078 (Note 7 and Note 8) were excluded from the computation of diluted weighted average shares outstanding for the three months ended March 31, 2026 (March 31, 2025 - convertible debentures of 50,938,127, stock options of 9,223,290, and warrants of 53,185,249, respectively) as their effect would be anti-dilutive. The if-converted value of the 2026 Convertible Debentures did not exceed the principal amount as of March 31, 2026.

**15. SEGMENTED INFORMATION**

The Company currently has four principal assets which represent the Company's reportable and operating segments. All operating segments are located in Nevada, United States. Results of the operating segments are reviewed by the Company's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segments and to assess their performance. The Company's CODM is the chief executive officer. The CODM uses adjusted loss from operations to evaluate each operation's financial performance. The Corporate and other segment relates to the corporate administration function and includes other non-pre-development properties in total assets. Inter-segment expenses and expense recoveries are not eliminated and shown in the respective segment. The results from operations for these reportable segments are summarized in the following tables:

**19. FINANCIAL INSTRUMENTS**

The Company examines the various financial risks to which it is exposed and assesses the impact and likelihood of occurrence. These risks may include credit risk, liquidity risk, currency risk, interest rate risk and other risks. Where material, these risks are reviewed and monitored by the Board.

**Fair value accounting**

The fair value hierarchy prioritizes the input to valuation techniques used to measure fair values as follows:

Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); and

Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

&nbsp;&nbsp;&nbsp;&nbsp;(i)The following table presents financial instruments measured at fair value on a recurring basis within the fair value hierarchy for level 1 and 2 financial instruments:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| | | **March 31, 2026** | **March 31, 2026** | December 31, 2025 | December 31, 2025 |
| | Level | Carrying amount | Fair value | Carrying amount | Fair value |
| Warrant liability - brokered placement | 1 | $17499 | $17499 | $18052 | $18052 |
| Warrant liability - other | 2 | $6215 | $6215 | $6065 | $6065 |

---

The Company calculates fair values based on the following methods of valuation and assumptions for level 1 and level 2:

**Financial assets and liabilities**

Financial assets other than the Company's derivative instruments described are carried at amortized cost. The fair value of cash and cash equivalents and receivables approximate their carrying value due to their short-term nature.

Financial liabilities not classified as fair value through the statement of operations are carried at amortized cost. Accounts payable and accrued liabilities approximate their carrying value due to their short term nature. The 2026 Convertible Debentures have a fair value of $322.0 million.

**Warrant liabilities**

The warrant liabilities are fair valued using a valuation model that incorporates such factors as the Company's share price volatility, risk-free rates and expiry dates.

The warrants issued in connection with the 2024 brokered placement are classified within level 1 of the fair value hierarchy as the warrants are listed on the TSX and or the NYSE American and therefore a quoted market price is available.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Fair value measurements using significant unobservable inputs (level 3):

The following table presents the changes in level 3 financial instruments:

(Stated in thousands of United States Dollars, except per share amounts)

&nbsp;&nbsp;&nbsp;&nbsp;(Unaudited)

The Company calculates fair values based on the following methods of valuation and assumptions for level 3 financial instruments as follows:

**NSR Royalty**

The NSR Royalty is measured at fair value at each reporting date (level 3). In determining fair value, management judgment is required with respect to significant unobservable input variables used in the valuation model. These inputs include estimates of life-of-mine production volumes, timing of production, forward commodity prices and Company-specific discount rates. Changes in fair value were recorded in other income and other expense in the Condensed Consolidated Statement of Operations.

**Silver Purchase Agreement**

The Silver Purchase Agreement is recognized as a financial liability at amortized cost and it contains two embedded derivatives; one in relation to the embedded silver price within the agreement and the other in relation to the gold substitution option whereby i-80 Gold can choose to deliver gold instead of silver at a ratio of 75:1, both are measured at fair value each reporting period (level 3). As at March 31, 2026, the gold substitution option was extinguished upon settlement of the annual minimum deliveries. In determining the fair value of the embedded derivatives at each reporting period, management judgment is required in respect to input variables of the financial model used for estimation purposes. These variables include such inputs as metal prices, discount rates and the Company's production profile. Gains and losses were recorded in other income and other expense in the Condensed Consolidated Statement of Operations.

**2026 Gold Prepay**

The 2026 Gold Prepay is recognized as a financial liability at amortized cost and contains an embedded derivative in relation to the embedded gold price within the agreement that is measured at fair value each reporting period (level 3). In determining the fair value of the embedded derivative at each reporting period, management judgment is required in respect to input variables of the financial model used for estimation purposes. These variables include such inputs as metal prices and discount rates. Gains and losses were recorded in other income and other expense in the Condensed Consolidated Statement of Operations.

**Orion Gold Prepay**

The Orion Gold Prepay was recognized as a financial liability at amortized cost and contained an embedded derivative in relation to the embedded gold price within the agreement that was measured at fair value each reporting period (level 3). In determining the fair value of the embedded derivative at each reporting period, management judgment is required in respect to input variables of the financial model used for estimation purposes. These variables include such inputs as metal prices and discount rates. Gains and losses were recorded in other income and other expense in the Condensed Consolidated Statement of Operations.

**Orion Convertible Loan**

The Convertible Loan contained conversion and change of control rights that were separately measured at fair value each reporting period (level 3). In determining the fair value at each reporting period, management judgment was required in respect to input variables of the financial model used for estimation purposes. These variables include such inputs as management's estimate of the probability and date of a change of control event, the Company's share price, share price variability, and discount rates. Gains and losses were recorded in other income and other expense in the Condensed Consolidated Statement of Operations.

**Three months ended March 31, 2026** 

• Revenue increased to $52.4 million, representing 10,590 ounces in gold sold<sup>1</sup> at an average realized gold price<sup>2</sup> of $4,941 per ounce, compared to $14.0 million represented by 4,952 ounces<sup>1</sup> at an average realized gold price<sup>2</sup> of $2,825 per ounce in the prior year period. The increase in revenue was primarily driven by higher gold sales at Granite Creek as a result of the finalization of the third-party toll processing agreement in March 2025 and a higher average realized gold price<sup>2</sup>.

• Gross profit increased to $16.1 million from $2.9 million in the prior year period due to increases in revenue.

• Net loss increased to $78.6 million compared to $41.2 million in the prior year period, due primarily to higher non-cash fair value revaluations on derivative financial instruments of $48.4 million driven by stronger metal prices. Additional non-cash losses on extinguishment of the gold prepay agreement, convertible loan, and convertible debentures of $7.1 million also contributed to lower net earnings, as well as financing expenses incurred in the amount of $9.9 million. Higher pre-development, evaluation and exploration expenses were incurred as the Company advances multiple projects within its development plan, which were partially offset by higher gross profit. Upon declaration of mineral reserves, certain pre-development, evaluation and exploration expenditures currently expensed, will be capitalized.

• Loss per share of $0.09 decreased from $0.10 loss per share in the prior year period primarily due to an increase in the number of outstanding common shares following the equity raise in May 2025.

<sup>1</sup>Gold ounces sold include attributable gold from mineralized material sales at a payable factor of 57% in 2026 (2025 - 59%).

<sup>2</sup>This is a Non-GAAP and Supplementary Financial measure; please see "Non-GAAP and Supplementary Financial Performance Measures" section.

------

• Adjusted loss increased to $28.6 million compared to $23.6 million in the prior year period due to increased spending on pre-development, evaluation and exploration expenses, partially offset by higher gross profit.

• Cash used in operating activities increased to $45.1 million compared to $22.7 million in the prior year period as a result of interest payments made on the extinguishment of legacy debt of $25.7 million.

• Cash and cash equivalents were $513.5 million as of March 31, 2026, an increase of $450.3 million compared to December 31, 2025, primarily due to the net proceeds received from the financing transactions to complete the Company's recapitalization plan, offset by higher capital expenditures compared to the prior year period driven by the commencement of the Lone Tree Plant refurbishment project, as well as the settlement of legacy debt obligations.

• The Company completed several financing transactions for total amount of $787.5 million. Gross proceeds of $662.5 million and net proceeds of $637.2 million were received on closing which completed the recapitalization plan ahead of the Company's mid-2026 target and established a fully funded development plan:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ March 16, 2026: Completed a net smelter return royalty for $250 million (the "NSR Royalty") with Franco-Nevada U.S. Corporation ("Franco-Nevada") of which $225 million was received on closing, an additional $25.0 million is expected to be made available to advance Mineral Point, contingent upon satisfaction of specified project conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ March 16, 2026: Entered into a gold prepayment facility with National Bank of Canada ("NBC") and Macquarie Bank Limited ("Macquarie") for up to $250 million including a $100 million accordion option, subject to customary conditions and lender approval (the "2026 Gold Prepay").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ March 23, 2026: Completed an offering of 3.75% unsecured convertible senior notes due 2031 in the aggregate amount of $287.5 million ("2026 Convertible Debentures").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Proceeds from the NSR Royalty were used to redeem the 2023 Convertible Debentures, Orion Gold Prepay, and the Orion convertible loan in the amount of $165.0 million.

• Completed approximately 7,000 meters of drilling, initiating the largest 12-month drill program in Company history. First quarter activities included infill drilling at Upper Archimedes underground to enhance mineral resource definition ahead of mining, resource definition drilling at Granite Creek underground beyond a planned feasibility study, and infill drilling at Mineral Point open pit to upgrade resource classification for the planned pre-feasibility study.

• Approved the construction decision to proceed with the Lone Tree Plant refurbishment during the first quarter of 2026 with capital commitments of $31.2 million at March 31, 2026, with approximately 50% of total project capital expected to be committed by mid-2026.

• Three-phase development plan remains on track with 2026 development priorities, as well as full year production, operating and pre-development evaluation, and exploration cost guidance for 2026.

• Strengthened the Board with the appointment of three new directors who bring highly relevant experience and proven track records in mining operations, mineral processing, finance, and capital markets.

**Strategy Overview**

i-80 Gold is executing a three-phase multi-asset development plan aimed at creating a mid-tier gold producer in Nevada. The near-term focus is on developing two high-grade underground refractory gold projects (Granite Creek and Archimedes), and the refurbishment and commissioning of the Lone Tree Plant, which is expected to serve as a central processing hub for underground refractory material from all three planned underground projects. Development of the Company's third underground mine (Cove) as well as its two large, open pit oxide projects (Granite Creek and Mineral Point) are expected to follow to support a long-term target of more than 600,000<sup>1</sup> ounces of annual gold output. All of the Company's properties are currently considered to be in the exploration stage as mineral reserves have yet to be defined.

In support of the three-phase development plan, the Company released Preliminary Economic Assessments prepared in accordance with NI 43-101 and a corresponding Initial Assessment prepared under S-K 1300, each published in the first quarter of 2025 (the "PEA"), covering all five gold projects. These PEAs outlined a clear and achievable path to gold output and cash flow growth. Permitting, technical studies, development work and ramp up are actively being advanced across the portfolio of five gold projects, as well as the Lone Tree Plant, in support of upcoming planned feasibility studies.

<sup>1</sup>Consolidated gold output estimates and average annual gold output targets are based on the most recent LOM output schedules disclosed in the latest technical studies filed for each respective project and related property: Granite Creek underground project, Archimedes underground project, Cove underground project, Granite Creek open pit project, and Mineral Point open pit project. These anticipated output figures are preliminary in nature and are based on mineral resources, which do not have demonstrated economic viability, and are not mineral reserves. In addition, each of the foregoing technical reports are preliminary economic assessments/initial assessments that are preliminary in nature and each include an economic analysis that is based, in part, on inferred mineral resources. Inferred mineral resources are considered too speculative geologically to have for the application of economic considerations applied to them that would enable them to be categorized as mineral reserves. As such, there is no certainty that the output targets will be realized. The anticipated output targets are also pending the refurbishment and commissioning of the Lone Tree Plant. The output targets presented herein are Company goals and not a projection of results and should not be taken as output guidance. All of the Company's projects are considered exploration stage projects under S-K 1300 because the Company has not determined mineral reserves at any of its properties pursuant to S-K 1300. With respect to Granite Creek underground and Archimedes underground, located on the Ruby Hill property, the Company has started extraction activities without determining mineral reserves. The following technical reports for each project and related property have been prepared in accordance with NI 43-101: Preliminary Economic Assessment Technical Report for the Cove Project, Lander County, Nevada (March 31, 2025); Preliminary Economic Assessment Technical Report for the Granite Creek Mine Project, Humboldt County, Nevada, USA (March 31, 2025); and Preliminary Economic Assessment NI 43-101 Technical Report for the Ruby Hill Project, Eureka Country, Nevada, USA (March 31, 2025). Corresponding technical reports prepared in accordance with S-K 1300 are as follows: Initial Assessment & Technical Report Summary for the Cove Project, Lander County, Nevada (March 26, 2025); Initial Assessment of the Granite Creek Mine, Humboldt County, NV (March 26, 2025); and Initial Assessment of the Ruby Hill Project, Eureka County NV (March 29, 2025).

------

Phase 1 of the development plan includes the current ramp up at i-80 Gold's first underground mine, Granite Creek, as well as commencing extraction at Archimedes, the second planned underground mine. A key milestone in Phase 1 is the refurbishment and commissioning of the Lone Tree Plant to unlock the full value of the Company's underground mines. Once commissioned, the Lone Tree Plant is expected to enable processing of underground mineralized material to shift from third-party toll-milling to owner-operated processing in 2028. Average annual gold output is expected to increase to a range of between 150,000 to 200,000 ounces of gold in Phase 1 beginning in 2028<sup>1</sup>.

Phase 2 of the development plan focuses on bringing two additional projects into operation: Cove, the third planned underground mine, and Granite Creek open pit. With four producing assets, average annual gold output is expected to increase to a range of between 300,000 to 400,000 ounces of gold in the early 2030s<sup>1</sup>, representing a significant step in i-80 Gold's transition to a mid-tier producer.

Phase 3 is anchored by the Mineral Point open pit project, which is expected to become the Company's largest producing asset and projected to help the Company achieve its target of an average annual gold output beyond 600,000 ounces in the early 2030s<sup>1</sup>. The recent financing transactions provides flexibility to accelerate the feasibility study and permitting work for the Mineral Point open pit project. With several feasibility and pre-feasibility studies currently in progress, the Company continues to identify opportunities to optimize the development schedule for Phase 1 and Phase 3.

**Recapitalization Plan**

Over the past 12 months, i-80 Gold executed on several financing initiatives that have led to the successful completion of its recapitalization plan. Most recently during the first quarter of 2026, the Company completed several key transactions including the NSR Royalty with Franco-Nevada for up to $250 million,the 2026 Gold Prepay with National Bank and Macquarie Bank for up to $250 million, and the issuance of the 2026 Convertible Debentures in the aggregate principal amount of $287.5 million. These financings completed the Company's broader recapitalization plan ahead of its mid-2026 target and align with the projected capital requirements and cash flows of the project development plan.

Overall, the recapitalization secured over $1 billion<sup>1</sup> in raised and available capital from early 2025 through the first quarter of 2026, materially strengthening the Company's balance sheet, providing funding certainty, and de-risking the development plan.

With the recapitalization complete, the Company believes it is now fully funded to advance Phase 1 and Phase 2 of the development plan<sup>1</sup>. Phase 1 and Phase 2 currently include advancing three underground projects (Granite Creek, Archimedes and Cove) and one open pit oxide project (Granite Creek open pit), as well as the refurbishment and commissioning of the Company's centralized Lone Tree Plant. Phase 1 and Phase 2 projects are expected to generate sufficient operating cash flow to fund Phase 3<sup>2</sup> which currently includes the development of the Mineral Point open pit oxide project. The Company now has the financial flexibility to bring forward infill drilling, engineering, and technical studies in support of the pre-feasibility study and future permitting actions for Mineral Point ahead of Phase 3. With several feasibility and pre-feasibility studies currently in progress, the Company continues to identify opportunities to optimize the development schedule for Phase 2 and Phase 3.

Following the successful completion of the recapitalization plan, the Company has discontinued the sale process for its non-core FAD property.

<sup>1</sup>The Company has secured over $1.0 billion in capital since the beginning of 2025 through a combination of financings. This includes (i) approximately $184 million in gross proceeds raised in May 2025 through a public offering and a concurrent private placement, with up to an additional $130 million assuming full exercise of the related in-the-money warrants over the next 18 months, (ii) a $250 million royalty financing with Franco-Nevada (of which $225 million was funded at closing on March 16, 2026 with approximately $165 million used to pay legacy debt obligations, and $25 million remains subject to drawdown conditions), (iii) convertible senior notes issued on March 23, 2026 for an aggregate principal amount of $287.5 million, and (iv) $150 million under the Gold Prepay Facility with National Bank of Canada and Macquarie Bank with an additional $100 million available under an accordion feature, subject to drawdown conditions.

<sup>2</sup>Based on capital costs, gold output estimates and average annual gold output targets in the most recent life of mine gold output schedules disclosed in the latest technical studies filed for each respective project and related property: the Lone Tree Facility, Granite Creek underground, Archimedes underground, Cove underground and Granite Creek open pit when using a gold price assumption of $3,600 per ounce for the purposes of anticipated cash flow from operations. While the economics of the latest technical studies were completed using a gold price assumption of $2,175 per ounce with gold price sensitivities of up to $3,000 per ounce, a gold price assumption of $3,600 per ounce is in line with current long term consensus prices.

**Financing Overview**

**Three months ended March 31, 2026**

In support of the recapitalization strategy, the Company completed the following financing transactions :

*NSR Royalty*

On March 16, 2026, the Company announced that it had completed the closing of the $250 million NSR Royalty financing in exchange for a 1.5% life of mine ("LOM") net smelter return royalty with Franco-Nevada, stepping up to a 3.0% LOM net smelter return royalty on January 1, 2031. The NSR Royalty applies to production from all mineral properties in the portfolio, including Granite Creek, Cove, the Ruby Hill Complex and Lone Tree.

Upon closing of NSR Royalty, $225 million was made available to the Company, of which $25 million is required to be allocated to the advancement of technical and permitting work for Mineral Point in 2026. An additional $25 million of the NSR Royalty is also expected to be made available in 2026 to further advance Mineral Point, following the expenditure of the initial disbursement toward the project. In total, the NSR Royalty allows the Company to allocate $50 million to advance exploration, technical work and early stage pre-permitting activities at Mineral Point in 2026.

------

*Gold Prepay*

On March 16, 2026, the Company closed a Gold Prepay facility with National Bank and Macquarie, for an initial advance of $150 million at closing, with a $100 million accordion feature. Upon closing, the Company has the obligation to deliver 39,978 ounces of gold over a 30-month period beginning in January 2028. The accordion feature provides access to an additional $100 million for a 24-month period upon closing of the facility, subject to customary conditions and lender approval. The Company anticipates executing the accordion feature in the first half of 2027, at which point the number of additional gold ounces to be delivered will be determined. The Company expects the total ounces to be delivered for the $250 million facility to represent approximately 15% of total gold output over the projected period of January 2028 to June 2030.

*2026 Convertible Debentures*

On March 23, 2026, The Company closed the 2026 Convertible Debentures for an aggregate principal amount of $287.5 million, which includes the upsized offering of $250 million and the exercises in full of $37.5 million option granted to the initial purchasers of the convertible debentures. The initial conversion rate of the 2026 Convertible Debentures is 519.4805 common share of the Company per $1,000 principal amount, equivalent to an initial conversion price of approximately $1.93 per share.

*Debt repayments*

With the proceeds received from the NSR Royalty, the Company redeemed all of its legacy debt obligations except for the silver purchase and sale agreement with Orion (the "Silver Purchase Agreement") during the first quarter of 2026. The 2023 Convertible Debentures were redeemed for total cash consideration of $72.9 million, with accrued interest and the 4% mandatory redemption premium settled through the issuance of 8.1 million common shares and a cash payment of $5.3 million. The Orion Convertible Loan was repaid for total consideration of $75.0 million , comprised of a cash payment of $69.7 million and the issuance of 3.0 million common shares with a fair value of $5.3 million. The remaining outstanding deliveries of 4,440 ounces of gold from the Orion Gold Prepay were redeemed with a cash payment of $22.4 million.

**DISCUSSION OF OPERATIONAL RESULTS**

The Company owns and operates four past producing gold properties in Nevada, one of the largest gold producing regions in the world. The Company continued to advance its exploration stage gold properties following successful exploration programs.

**Granite Creek Property**

The Granite Creek property includes the Granite Creek underground project, a fully permitted, constructed and operating mine, and the Granite Creek open pit oxide deposit adjacent to the underground project. Granite Creek underground is the Company's first brownfield project to be redeveloped and is currently ramping up towards steady-state gold output.

Gold was initially discovered at Granite Creek in the mid to late 1930's and includes the former Pinson mine. Approximately one million ounces have been produced from the property since that time. The Granite Creek property is comprised of several land parcels which now encompass approximately 4,480 acres, located in the Potosi mining district, approximately 27 miles northeast of Winnemucca, within Humboldt County, Nevada. The seven-square miles of land contain all areas of past gold production and the area of mineral resources (underground and open pit).

<sup>1</sup>Low-grade mineralized material extracted as part of the mining process that is below cut-off grade but incrementally economic.

<sup>2</sup>Gold ounces sold include attributable gold from mineralized material sales at a payable factor of 57% in 2026 (2025 - 59%).

<sup>3</sup>Total mineralized material mined consists of sulfide, oxide, and low-grade mineralized material.

*Granite Creek Underground*

Mineralized material mined at Granite Creek underground is processed as follows: (i) sulfide mineralized material is processed at a third-party processing facility and subject to a toll milling agreement entered into in March 2025, (ii) high-grade oxide mineralized material is subject to an ore sales agreement, (iii) low-grade oxide mineralized material shipped as part of the ore sales agreement beginning in the first quarter of 2026, and (iv) residual leaching of low-grade oxide material previously placed on a segregated section of the Company's Lone Tree heap leach facility.

Mining activities at Granite Creek for the three months ended March 31, 2026 were impacted by a main surface electrical substation transformer fire that occurred in January 2026, resulting in a loss of power to the underground operations. Temporary diesel generators were installed shortly after the incident to allow for mining operations to resume with minimal impact to the mine plan, and permanent replacement infrastructure was installed in mid-March.

Throughout the quarter, waste development in the main decline and access ramps continued to progress according to the mine plan, despite limited access in January and early February due to the loss of power incident. For the remainder of the quarter, decline advance rates exceeded plan, and from the second quarter onwards, the development rate is expected to be sufficiently ahead of the mine workings to allow for the efficient extraction of the mineralized material for the foreseeable future.

Water inflow volumes to the mine remained largely unchanged and continue to be managed well using the current underground pumping system, which presently operates near capacity. An enhanced pumping system that includes expanded sumps and higher capacity pumps will be installed throughout the year to allow for an increase in overall water discharge capacity of the contact water as the mine progresses at depth. Further, commissioning of a second water treatment plant currently under construction remains on track for June 2026, which is expected to increase surface water treatment capacity to support the Company's long-term groundwater management objectives.

The Company continues to encounter elevated levels of oxide mineralized material compared to levels anticipated in the March 2025 PEA at Granite Creek underground.

As at March 31, 2026, the Company had a sulfide stockpile with over 4,000 recoverable ounces of gold due to the availability of third-party processing. The Company expects this stockpile to be processed during the second quarter of 2026.

Capital spend at Granite Creek consisted of costs related to the water treatment plant, RIB construction, and the electrical substation replacement.

------

Pre-development, evaluation, and exploration expenses were $11.4 million for the three months ended March 31, 2026, which were primarily related to underground mine development and infill drilling to upgrade mineral resources and step-out drilling beyond the drill program completed in 2025 in advance of the feasibility study.

During the three months ended March 31, 2026, the Company continued infill and step-out drilling at Granite Creek, completing approximately 1,925 meters of core drilling across the property. The underground drill program remained focused on infill drilling to support resource conversion and mine planning, while surface drilling targeted northerly step-out holes on the South Pacific Zone and Rangefront fault to test the potential for resource expansion. The updated mineral resource estimate will incorporate drilling data from 2023, 2024, and 2025, and will utilize a revised resource modeling approach. The feasibility study is expected to be completed in the second quarter of 2026.

New assay results from 40 holes reported on January 20, 2026, continued to demonstrate robust high-grade mineralization throughout the South Pacific Zone confirming expansion of the mineralized envelope and potential for mineral resource expansion to the north and at depth.

*Granite Creek Open Pit*

Following the completion of the Granite Creek open pit PEA, a pre-feasibility trade-off study commenced. Simultaneously, technical trade-off analyses are being conducted to optimize project economics. Based on preliminary assessments of potential environmental impacts, the project may require preparation of an Environmental Impact Statement ("EIS") under the Bureau of Land Management ("BLM") process. Early-stage pre-permitting activities and technical studies are currently underway, followed by planned baseline field studies commencing in 2027 to support the National Environmental Policy Act ("NEPA") permitting process.

**Ruby Hill Property**

The Ruby Hill property includes the Archimedes underground project, the Company's second planned underground mine for which construction began during 2025, and the Mineral Point open pit, which is a large oxide gold and silver deposit with the potential to become the Company's largest gold producing asset.

During the 1990's, an ore body was discovered, which became the Archimedes open pit. Later discoveries included the Ruby Deeps Carlin-style sulfide mineralized deposit with the most recent discovery of the Hilltop zone. The Ruby Hill property is located within the Battle Mountain-Eureka trend, a northwest-trending geological belt located in north-central Nevada. The property contains gold, silver and base metal mineralization and exploration targets within the Archimedes underground project and Mineral Point open pit project. Processing infrastructure at Ruby Hill includes a primary crushing plant, grinding mill, leach pad, and carbon-in-column circuit, as well as associated mining infrastructure. Some of the existing facilities are expected to be utilized for Mineral Point, however new crushing, a Merrill Crowe plant, and heap leach facilities will be required.

During the first quarter of 2025, the Company finalized a PEA for the Ruby Hill property covering both Archimedes underground and Mineral Point open pit projects.

*Archimedes underground project*

During the three months ended March 31, 2026, underground development at the Archimedes project advanced ahead of schedule, with approximately 660 meters completed during the quarter supported by favorable ground conditions. A new dewatering well was completed during the quarter, with pump testing scheduled for the second quarter of 2026. Predictive groundwater modeling and geochemical technical studies are ongoing in support of the Lower Archimedes permitting process. The timeframe for first gold mined is in the second half of 2026.

------

The Company also completed 4,262 meters of infill drilling at the 426 zone of Upper Archimedes, with infill drilling of the Ruby Deeps zone within Lower Archimedes expected to commence in the second quarter of 2026, following the completion of the exploration drift. Together, these programs will form the technical basis for the Archimedes Underground feasibility study, which is targeting late in the first quarter of 2027, pending the potential expansion of the current drill program. New assay results from the first 20 holes from the Upper Archimedes drill program were reported subsequent to the first quarter on April 8, 2026, and continue to demonstrate high-grade mineralization throughout Upper Archimedes, returning high-grade intercepts consistent with the current geological model.

Capital expenditures for the three months ended March 31, 2026 were primarily from construction of a dry room trailer, office infrastructure upgrades, power upgrades and mine load centers for the underground.

Pre-development, evaluation and exploration expenditures were $12.4 million for the three months ended March 31, 2026, primarily due to increased underground development at the Archimedes underground project which began in the third quarter of 2025. During the first quarter of 2026, the higher expenditure is driven by a decline advance rate that exceeded expectations, resulting in accelerated development activity and the construction of surface infrastructure.

The Company continues to leach the historic leach pads on the Ruby Hill property recovering minor amounts of gold. For the residual leaching process, management continues to focus on improving solution flows to control ponding and optimizing cyanide application rates with the objective of increasing production from the historic leach pad during the first quarter of 2026.

*Mineral Point open pit project*

At Mineral Point open pit, two surface core drill rigs completed 750 meters of surface core drilling during the first quarter of 2026. This drill program was designed to support a pre-feasibility trade-off study covering hydrogeology, metallurgy, and an optimized mine plan. Mineral Point currently hosts the Company's largest gold and silver mineral resources. The $250 million NSR Royalty completed in the first quarter of 2026 includes $50 million allocated to advancing infill drilling, engineering, and early-stage pre-permitting at Mineral Point in 2026 in support of a pre-feasibility study anticipated for completion in 2027.

**Cove Project**

Cove is an advanced stage exploration project and is expected to be the Company's third underground mine. It covers 30,923 acres and is located 32 miles south of the town of Battle Mountain, in the Fish Creek Mountains of Lander County, Nevada, and lies within the McCoy Mining District. Modern exploration for copper and gold in the McCoy Mining District started in the 1960s. The Cove property is, for the most part, on land controlled by the U.S. Department of Interior, BLM and patented mining claims and consists of 100%-owned unpatented claims and twelve leased patented claims.

NEPA permitting activities are underway with the BLM at Cove in anticipation of an EIS. i-80 Gold is actively advancing major permit applications with the goal of aligning regulatory approvals with planned development timelines.

**Lone Tree Plant**

The Lone Tree property is a historic producing mine that ceased mining operations in 2006 and is located within the Battle Mountain-Eureka Trend, midway between the Company's Granite Creek property and Cove underground project. The Lone Tree open pit is not currently included in the new development plan. The Lone Tree Plant is currently non-operational and a construction decision on its refurbishment was made by the Board of Directors during the first quarter of 2026. i-80 Gold is one of two gold companies in Nevada with an autoclave processing plant (the other being owned by Nevada Gold Mines Inc., a joint venture between Barrick Mining Corporation and Newmont Corporation).

The Lone Tree Plant is envisioned to process material from the Company's three underground mines, Granite Creek, Archimedes, and Cove, to establish a regional hub-and-spoke mining and processing model. Upon refurbishment and commissioning, the Lone Tree Plant will allow the Company to transition from toll milling to owner-operated processing. This shift is expected to materially increase operating margins and enhance free cash flow generation.

The leaching of the historic leach pad at Lone Tree continues to produce gold at profitable quantities.

*Lone Tree Plant Refurbishment Project*

During the fourth quarter of 2025, an engineering study was completed for the Lone Tree Plant refurbishment, which updated an internal feasibility study completed in 2023 to incorporate design optimizations, value engineering initiatives, a filtered tailings system, and updated cost estimates to support an improved execution strategy. A positive construction decision was made in the first quarter of 2026 alongside the successful completion of the Company's recapitalization. Plant commissioning is anticipated at the end of 2027.

The Lone Tree Plant is expected to operate at a nameplate capacity of 2,268 tonnes per day or 827,806 tonnes per annum, consistent with historic production rates. The processing circuit will incorporate an integrated pressure oxidation ("POX") and carbon-in-leach ("CIL") circuits capable of processing both refractory (sulfide) and non-refractory (oxide) mineralized material. The scope of work includes a combination of improved design components and the replacement of some existing infrastructure aimed at modernizing the Lone Tree Plant to improve process efficiency and operating flexibility, and to meet new environmental compliance standards, including the upgrade of the existing autoclave to a modern pressure oxidation circuit.

The refurbishment has a capital cost estimate of $412 million, inclusive of contingency, owner's costs, and first fills, plus $18 million in capital spares for a total of $430 million.

The Lone Tree Plant is permitted for the existing operational components in use. The approval of new and revised permit applications pertaining to air quality, mercury control, water pollution control, reclamation management, and other secondary programs for the new design remain outstanding. The Company submitted the necessary applications for air quality, mercury control and water quality environmental permits in the first quarter of 2026, ahead of schedule. Various construction activities are expected to commence upon the approval of needed permits, the Company does not envision delays in the construction schedule due to the permitting process at this time.

Capital expenditures for the three months ended March 31, 2026 were primarily related to the refurbishment of the Lone Tree Plant.

During the first quarter, the Company provided Hatch with a formal Notice to Proceed ("NTP") for the Lone Tree refurbishment project. In preparation, procurement for long lead equipment and detailed engineering activities commenced in 2025 to optimize the schedule. At present, the project is on plan for the first gold pour in December 2027 and costs remain in line with the control estimate issued in November 2025. As of March 31, 2026, total construction commitments were $31.2 million, with approximately 50% of the project's commitments expected towards the end of the first half of 2026. On-site early works commenced in the second quarter of 2026, which includes the mobilization of the Hatch construction team and the initiation of equipment demolition, building refurbishment and repairs, and installation of lighting and electrical replacement and upgrades.

For the three months ended March 31, 2026, the Company incurred higher pre-development, evaluation and exploration expenses, compared to the prior year period reflecting the increased activity to advance key development milestones across all five gold projects within its development plan. At Granite Creek, expenses increased primarily due to increased underground development expenditures, largely related to dewatering infrastructure, along with drilling costs and other technical work related to the preparation of a feasibility study targeted for the second quarter of 2026.

At Ruby Hill, spending increased primarily due to expenditures related to Archimedes underground development as the advancement rate of the decline exceeded expectations, resulting in accelerated development activity and higher drilling expenses related to geologic mapping of the underground and construction of the drill bays. In the prior year quarter, no underground development activity had commenced.

Cove pre-development, evaluation and exploration expenditures decreased in the current quarter compared to the prior year quarter as the feasibility study work completed in the first quarter of 2026 was lower than the drilling cost performed during the first quarter of 2025.

*General and administrative* 

For the three months ended March 31, 2026, general and administrative expenses are higher compared to the prior year period primarily due to the revaluation of share based compensation due to the increase in the Company's share price of approximately $1.6 million.

**DISCUSSION OF FINANCIAL POSITION**

**Balance Sheet Review** 

*Assets*

Cash and cash equivalents increased by $450.3 million from $63.2 million at December 31, 2025 to $513.5 million as at March 31, 2026. Refer to the Liquidity and Capital Resources and cash flow section below for further details.

Property, plant and equipment have increased by $13.7 million due to increase in the Lone Tree Plant refurbishment activities, Granite Creek and Ruby Hill capital expenditures.

Other assets have increased due to the 2026 Gold Prepay derivative asset recognized in the amount of $7.9 million.

*Liabilities*

Total liabilities as at March 31, 2026 were $877.4 million compared to $356.6 million as at December 31, 2025. The increase was due primarily to the completion of the recapitalization including the closing of the 2026 Convertible Debentures, the NSR Royalty, and 2026 Gold Prepay and increases in other liabilities related to the Silver Prepay derivative which increased due to metal prices.

| Working capital | **493645** | (37919) |

---

Changes in cash and cash equivalents are discussed in the cash flow section. The working capital position has significantly improved from December 31, 2025 due to an increase in cash received from the recapitalization plan which includes the NSR Royalty, 2026 Convertible Debenture, and the 2026 Gold Prepay, net of the existing debt that was repaid.

For the three months ended March 31, 2026, the Company completed its recapitalization plan by securing over $1 billion in committed and available capital. As a result, the Company is fully funded to advance Phase 1 and Phase 2 of its development plan and is in a strong liquidity position. Additional liquidity is available through the remaining $25.0 million from the NSR Royalty, subject to satisfaction of specified project expenditure conditions, the $100.0 million accordion feature under the 2026 Gold Prepay, and future proceeds from warrant exercises.

Orion will pay the Company an ongoing cash purchase price equal to 20% of the prevailing silver price.

Until the delivery of an aggregate of 1.2 million ounces of silver, the Company is required to deliver the following minimum amounts of silver ("the Annual Minimum Delivery Amount") in each calendar year: (i) in 2022, 300,000 ounces, (ii) in 2023, 400,000 ounces, (iii) in 2024, 400,000 ounces, and (iv) in 2025, 100,000 ounces.

At the Company's sole option, the obligation to make up the Shortfall Amount to Orion may be satisfied by the delivery of refined gold instead of refined silver, at a ratio of 1/75th ounce of refined gold for each ounce of refined silver.

**NON-GAAP AND SUPPLEMENTARY FINANCIAL PERFORMANCE MEASURES**

The Company has included certain non-GAAP commonly used in the mining industry that are not defined under US GAAP in this document. These include adjusted loss, adjusted loss per share, and average realized price per ounce. These measures are not defined under US GAAP, and therefore, they may not be comparable to similar measures employed by other companies. Management believes these measures in addition to measures determined in accordance with US GAAP provide investors with useful information to evaluate the Company's underlying operations and financial performance. Supplementary financial measures represents a component of a GAAP number. The measures presented are intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with US GAAP and should be read in conjunction with the Company's Financial Statements.

*Definitions*

"Average realized gold price" per ounce of gold sold is a supplementary financial measure and the calculation is shown below.

"Adjusted loss" and "adjusted loss per share" are non-GAAP financial performance measures that the Company considers to better reflect normalized earnings because it eliminates temporary or non-recurring items such as: gain and losses on fair value measurements, loss on loan extinguishment, loss on Convertible Loans and finance fee expense. Adjusted loss per share is calculated using the weighted average number of shares outstanding under the basic calculation of earnings per share.

(e) fifth, to the extent of any excess of such payments or proceeds, to the payment to or upon the order of the Company or to whosoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct. Notwithstanding the foregoing, in no event shall payments or proceeds received by the Administrative Agent from a Guarantor or in respect of its Collateral be applied against Excluded Swap Obligations of such Guarantor. (2) If any Secured Party shall obtain Payment in respect of any of its Secured Liabilities (including by way of set-off or counterclaim) resulting in such Secured Party receiving payment of a greater proportion of the aggregate amount of its Secured Liabilities than the proportion received by any other Secured Party on its Secured Liabilities, then the Secured Party receiving such greater proportion shall purchase (for cash at face value) participations in the Secured Liabilities owed to other Secured Parties (as applicable) to the extent necessary so that the benefit of all such payments shall be shared by the Secured Parties rateably in accordance with the aggregate amount of their respective Secured Liabilities; provided that (a) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (b) this Section 2.3(2) shall not apply to: (a) any Payment made by the Company pursuant to and in accordance with the express terms of this Agreement; (b) any Payment obtained by a Bank as consideration for the assignment of, or sale of a participation in, any of its Secured Prepaid Forward Obligations; (c) netting under or as between Secured Hedge Arrangements; (d) any Permitted Prepaid Forward Payment; and (e) any Permitted Hedge Payment.

The Company hereby consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Bank acquiring a participation pursuant to the foregoing arrangements may exercise against the Company rights of set-off and counterclaim with respect to such participation as fully as if such Bank were a direct creditor of the Company in the amount of such participation. 2.4 Currency Indemnity. If, for the purposes of obtaining judgment in any court in any jurisdiction with respect to this Agreement or any other Credit Document, it becomes necessary to convert into a particular currency (the "Judgment Currency") any amount due under this Agreement or under any other Credit Document in any currency other than the Judgment Currency (the "Currency Due"), then conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which judgment is given. For this purpose "rate of exchange" means the rate at which the Administrative Agent is able, on the relevant date, to purchase the Currency Due with the Judgment Currency in accordance with its normal practice. In the event that there is a change in the rate of exchange prevailing between the Business Day immediately preceding the day on which the judgment is given and the date of receipt by the Administrative Agent of the amount due, the Company shall, on the date of receipt by the Administrative Agent, pay such additional

If the amount of the Currency Due which the Administrative Agent is so able to purchase is less than the amount of the Currency Due originally due to it, the Company shall indemnify and save the Administrative Agent and the Banks harmless from and against all loss or damage arising as a result of such deficiency. This indemnity shall constitute an obligation separate and independent from the other obligations contained in this Agreement and the other Credit Documents, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by the Administrative Agent from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due under this Agreement or any other Credit Document or under any judgment or order.

A notice of the Administrative Agent to any Payment Recipient under this Section 8.11(1) shall be conclusive, absent manifest error. (2) Error Designation. Without limiting the immediately preceding Section 8.11(1), each Bank, or any Person who has received funds on behalf of a Bank (and each of their respective successors and assigns) under or pursuant to any of the Credit Documents, hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in this Agreement or in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Bank or Bank, or other such recipient, otherwise becomes aware was transmitted, paid, or received, in error or by mistake (in whole or in part), then in each such case: (a) it acknowledges and agrees that (i) in the case of immediately preceding clauses (x) or (y), an error and mistake shall be presumed to have been made (absent express written confirmation from the Administrative Agent to the contrary), or (ii) an error and mistake has been made (in the case of immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and (b) such Bank shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one Business Day of its knowledge of the occurrence of any of the circumstances described in the immediately preceding clauses (x),(y) and (z)) notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this Section 8.11(2). For the avoidance of doubt, the failure to deliver a notice to the Administrative Agent pursuant to this Section 8.11(2) shall not have any effect on a Payment Recipient's obligations pursuant to Section 8.11(1) or on whether or not an Erroneous Payment has been made. (3) Set-off. Each Bank hereby authorizes the Administrative Agent to set-off, net and apply any and all amounts at any time owing to such Bank under any Credit Document, or otherwise payable or distributable by the Administrative Agent to such Bank under any Credit Document with respect to any payment of principal, interest, fees or other amounts, against any amount that the Administrative Agent has demanded to be returned under Section 8.11(1). (4) Secured Liabilities Satisfaction. The Parties agree that (x) irrespective of whether the Administrative Agent may be equitably subrogated, in the event that an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Administrative Agent shall be subrogated to all the rights and interests of such Payment Recipient (and, in the case of any Payment Recipient who has received funds on behalf of a Bank, to the rights and interests of such Bank, as the case may be) under the Credit Documents with respect to such amount (the "Erroneous Payment Subrogation Rights"), and (y) an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Secured Liabilities owed by the Company or any other Credit Party; provided that this Section 8.11(4) shall not be interpreted to increase (or accelerate the due date for), or have the effect of increasing (or accelerating the due date for), the obligations of the

Except pursuant to an Erroneous Payment Deficiency Assignment or the exercise of any Erroneous Payment Subrogation Rights (or any equivalent equitable subrogation rights), the Company shall not have any liability to the Administrative Agent for any Erroneous Payment or any interest, loss, cost or damages related thereto or arising therefrom under any provision of this

(a) The Company agrees that the Administrative Agent may, but shall not be obligated to, make Communications (as defined below) available to the other Banks by posting the Communications on Debt Domain, Intralinks, Syndtrak, ClearPar or a substantially similar electronic system (each an "Electronic System"). Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Closing Date, a user ID/password authorization system) and the Approved Electronic Platform is secured through a per-deal authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Banks and the Company acknowledges and agrees that the distribution of material through an electronic medium is not necessarily secure, that the Administrative Agent is not responsible for approving or vetting the representatives or contacts of any Bank that are added to the Approved Electronic Platform, and that there may be confidentiality and other risks associated with such distribution.

No failure or delay by the Administrative Agent or any Bank in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Banks hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Company therefrom shall in any event be effective unless the same shall be permitted by Section 9.2(2), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the entry into a Secured Prepaid Forward Arrangement shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Bank may have had notice or knowledge of such Default at the time. (2) Amendments - General. Neither this Agreement nor any other Security Document (or any provision hereof or thereof) may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Company and the Required Banks or by the Company and the Administrative Agent with the consent of the Required Banks (and for greater certainty, any such waiver, amendment or modification shall not require any consent or other agreement of any Credit Party other than the Company, notwithstanding that any such Credit Party may be a party to this Agreement or any other Credit Document); provided that no such agreement shall: (a) increase or decrease the amount of any Secured Prepaid Forward Commitment of any Bank except in accordance with Section 2.1(3); (b) change Section 2.3 in a manner that would alter the sharing of payments required thereby; (c) amend the definition of Permitted Prepaid Forward Payment, Secured Prepaid Forward Arrangement, Secured Liabilities or any of their constituent defined terms (other than Event of Default); (d) change any of the provisions of this Section 9.2 or the definition of "Required Banks" or any other provision hereof specifying the number or percentage of Banks required to waive,

The Company also acknowledges that no Bank has any obligation to use in connection with the transactions contemplated by the Credit Documents, or to furnish to the Company or any of its Subsidiaries, confidential information obtained from other companies. 9.22 Acknowledgement Regarding Any Supported QFCs. To the extent that the Credit Documents provide support, through a Guarantee or otherwise, for any Hedge Arrangement, Prepaid Forward Arrangement or any other agreement or instrument that is a QFC (such support, "QFC Credit Support", and each such QFC, a "Supported QFC"), the Parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the "U.S. Special Resolution Regimes") in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Credit Documents and any Supported QFC may in fact be stated to be governed by the laws of, inter alia, the Province of Ontario.

In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Credit Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Credit Documents were governed by the laws of the United States or a state of the United States. 9.23 LIMITATION OF LIABILITY. NO CLAIM MAY BE MADE BY ANY GROUP PARTY, ANY BANK OR ANY OTHER PERSON AGAINST ANY INDEMNITEE ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS RESULT OF, ANY CREDIT DOCUMENT, THE TRANSACTIONS, OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, AND EACH GROUP PARTY AND BANK HEREBY WAIVE TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ALL SUCH CLAIMS, WHETHER OR NOT ACCRUED AND WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS FAVOUR.

## Exhibit 95.1

Exhibit 95.1

**Mine Safety Information**

The following disclosures are provided pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Act") and Item 104 of Regulation S-K, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the "Mine Act"). The disclosures reflect our U.S. mining operations only as the requirements of the Act and Item 104 of Regulation S-K do not apply to our mines operated outside the United States.

*Mine Safety Information.* Whenever the Federal Mine Safety and Health Administration ("MSHA") believes a violation of the Mine Act, any health or safety standard or any regulation has occurred, it may issue a citation which describes the alleged violation and fixes a time within which a U.S. mining operator must abate the alleged violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order removing miners from the area of the mine affected by the condition until the alleged hazards are corrected. When MSHA issues a citation or order, it generally proposes a civil penalty, or fine, as a result of the alleged violation, that the operator is ordered to pay. Citations and orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed. The number of citations, orders and proposed assessments vary depending on the size and type (underground or surface) of the mine as well as by the MSHA inspector(s) assigned. In addition to civil penalties, the Mine Act also provides for criminal penalties for an operator who willfully violates a health or safety standard or knowingly violates or fails or refuses to comply with an order issued under Section 107(a) or any final decision issued under the Act.

The below table reflects citations and orders issued to us by MSHA during the quarter ended March 31, 2026. **The proposed assessments for the quarter ended March 31, 2026** were taken from the MSHA data retrieval system as of May 6, 2026.

Additional information about the Act and MSHA references used in the table follows.

• *Section 104(a) Significant and Substantial ("S&S") Citations*. Citations received from MSHA under section 104(a) of the Mine Act for violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard.

• *Section 104(b) Orders*. Orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

• *Section 104(d) S&S Citations and Orders*. Citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory, significant and substantial health or safety standards.

• *Section 110(b)(2) Violations*. Flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

• *Section 107(a) Orders*. Orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an "imminent danger" (as defined by MSHA) existed.

Exhibit 95.1

*Pattern or Potential Pattern of Violations*. **During the quarter ended March 31, 2026, <u>none of the mines operated by the Company</u>** received written notice from MSHA of (a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under section 104(e) of the Mine Act or (b) the potential to have such a pattern.

*Pending Legal Actions*. Legal actions pending before the Federal Mine Safety and Health Review Commission (the "Commission"), an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act, may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA or complaints of discrimination by miners under section 105 of the Mine Act. The following is a brief description of the types of legal actions that may be brought before the Commission.

• *Contests of Citations and Orders*. A contest proceeding may be filed with the Commission by operators, miners or miners' representatives to challenge the issuance of a citation or order issued by MSHA.

• *Contests of Proposed Penalties (Petitions for Assessment of Penalties)*: A contest of a proposed penalty is an administrative proceeding before the Commission challenging a civil penalty that MSHA has proposed for the alleged violation contained in a citation or order. The validity of the citation may also be challenged in this proceeding as well.

• *Complaints for Compensation:* A complaint for compensation may be filed with the Commission by miners entitled to compensation when a mine is closed by certain withdrawal orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due miners idled by the orders.

• *Complaints of Discharge, Discrimination or Interference*: A discrimination proceeding is a case that involves a miner's allegation that he or she has suffered a wrong by the operator because he or she engaged in some type of activity protected under the Mine Act, such as making a safety complaint.

• *Applications for Temporary Relief*: An application for temporary relief from any modification or termination of any order or from any order issued under section 104 of the Mine Act.

• *Appeals of Judges' Decisions or Orders to the Commission*: A filing with the Commission of a petition for discretionary review of a Judge's decision or order by a person who has been adversely affected or aggrieved by such decision or order.

**<u>During the quarter ended March 31, 2026, none of the mines operated by the Company</u>** had any pending legal actions before the Commission, any legal actions instituted, or any legal actions resolved.
