DEVELOPMENT PLAN AND RECAPITALIZATION

In 2025, i-80 Gold focused on advancing its three-phased development plan to create a mid-tier gold producer by the early 2030s. Phase one includes the ramp up of Granite Creek underground, the construction of the Archimedes underground mine, and the refurbishment of the Company's Lone Tree Plant which will act as a central processing facility. This phase is expected to increase i-80 Gold's production to between 150,000 to 200,000 ounces of gold⁽³⁾ from less than 50,000 ounces currently. Phase two involves the development of the Cove underground project and Granite Creek open pit, which is expected to increase companywide production to between 300,000 to 400,000 ounces of gold⁽³⁾. Phase three is expected to bring Mineral Point, a large open pit heap leach project, into operation increasing production levels to over 600,000 ounces of gold⁽³⁾.

During the year, the Company significantly strengthened its balance sheet through several financing initiatives which ultimately culminated in the significant financing package announced in February 2026. The financing package of up to $500 million consists of a royalty sale of $250 million with Franco-Nevada Corporation, and a gold prepayment facility with National Bank of Canada and Macquarie Bank Limited for an initial $150 million together with an uncommitted accordion feature for an additional $100 million⁽⁴⁾ (collectively, the "Financing Package"). The royalty sale is subject to customary closing conditions and is anticipated to be completed on or about March 17, 2026, and closing of the prepayment facility is subject to customary closing conditions, including but not limited to, an intercreditor arrangement and is anticipated to be completed by the end of the first quarter of 2026. The Company has issued a notice of redemption of its existing convertible debentures as part of the recapitalization plan to provide the required security under the Financing Package. The Company is also contemplating the potential sale of a non-core asset and the issuance of debt or equity, or a combination thereof, to complete the recapitalization plan, which once complete, is expected to fully fund Phase one and Phase two of the development plan^(3,6).

Upon completion of the Financing Package, the proceeds will be used to refurbish the Lone Tree Plant, fund resource expansion and infill drilling, and advance development, technical and permitting activities across the Company's portfolio of assets, as well as for working capital purposes. The proceeds will also be used to extinguish the Company's existing debt obligations of approximately $175 million⁽⁵⁾. The Financing Package also provides flexibility to accelerate the feasibility study and permitting work for the Mineral Point open pit project. With several feasibility studies currently in progress, we continue to identify opportunities to optimize the development schedule for Phases two and Phase three.

Outlook

The Company achieved its 2025 guidance of 30,000 to 40,000 ounces, reporting 31,930 ounces of gold output, despite gold production being impacted by the timing of third-party processing. Granite Creek underground contributed 22,977 ounces within its expected range of between 20,000 to 30,000 ounces⁽³⁾. The Company's two residual heap leach operations contributed 8,953 ounces of gold compared to the approximately 10,000 ounces expected in 2025. Had timing of processing by the Company's third-party processor been in line with plan, production for the year would have been at the higher end of the guidance range, given as at the end of December 2025, over 6,500 recovered ounces of gold were stockpiled at the third-party processing facility. 

In 2025, the Company met its expected growth expenditures of between $40 million to $50 million that is primarily recognized in pre-development, evaluation and exploration expenditures.

2026 Outlook

The Company's 2026 production, operating and pre-development, evaluation and exploration cost guidance is summarized below:

At Granite Creek, guidance is largely in line with the Preliminary Economic Assessment prepared in accordance with NI 43-101 and the corresponding Initial Assessment prepared under S-K 1300 each published in the first quarter of 2025 (collectively, the "PEA"), with some exceptions. As previously disclosed, the impact of underground water was not reflected in the PEA, resulting in (i) higher waste development rates required to catch up on development, (ii) additional capital required for dewatering infrastructure, (iii) lower grades processed in 2026 due to the delay in accessing the higher grade South Pacific Zone. Additionally, relative to the PEA, both recoveries and processing costs are higher due to the toll milling agreement entered into subsequent to the release of the PEA. Material mined is approximately 20% higher than the PEA, while mining, G&A and development and sustaining costs are in line. Step out and infill drilling budgets have been increased relative to the PEA due to the success of the 2025 program.

At Archimedes, tonnes and mined grade, and development costs are largely in line with the PEA. The exception is processing costs related to the new toll milling agreement entered into following the release of the PEA. Costs related to the Archimedes feasibility study have been brought forward to 2026 versus 2028 in the PEA. This includes infill drilling costs with an additional $10 million for an exploration drift and the cost of drilling longer holes.

Costs associated with pre-development activities at Mineral Point have been brought forward to 2026 from 2028. Resource expansion and infill drilling along with technical and early permitting activities are expected to total between $40 to $45 million and be funded through the portion of the proceeds from the Franco-Nevada Corporation royalty allocated to Mineral Point.

Other technical work, permitting activities, and holding costs are largely in line with estimates published in the respective PEAs.

This outlook, including expected results and targets, is subject to various risks, uncertainties and assumptions, which may impact future performance and the Company's ability to achieve the results and targets discussed in this section. Please refer to the "Cautionary Statement on Forward-Looking Information" section. The Company may, but is under no obligation to, update this outlook depending on changes in metal prices and other factors.

OPERATIONAL AND FINANCIAL OVERVIEW

"Operations progressed well through the fourth quarter, closing out a busy and productive year," said Paul Chawrun, Chief Operating Officer. "At Granite Creek underground, operations are on plan with ongoing upgrades to the water management infrastructure, resulting in expected improvements to the development rates and main decline advancement in 2026. The exploration campaign to infill drill the South Pacific Zone reported strong results to enhance the resource definition and will form the basis of the upcoming feasibility study."

"At Ruby Hill, development of the Archimedes underground continues to progress very well with advancement rates, infrastructure, and resource definition of the upper 426 zone ahead of plan. A key focus for the next several months will be to advance the main decline towards initiation of the exploration drift to allow for the progression of the feasibility-level technical work for Ruby Deeps and the 426 zone at depth. At Lone Tree, work has been ongoing with the initial basic engineering and the long lead procurement packages as planned, with project completion remaining for first pour by December 31, 2027, as outlined in the Class 3 engineering study announced December 2025," added Mr. Chawrun. 

"Looking ahead to 2026, the exploration programs include additional resource definition and exploration drilling at Granite Creek, alongside substantial drilling campaigns planned for Ruby Deeps within lower Archimedes and at Mineral Point. We expect to have another productive year as we continue to prove out the potential of our asset base," added Mr. Chawrun.

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, currently in early-stage permitting and technical work. Granite Creek underground is the Company's first brownfield project to be redeveloped and is currently ramping up towards steady-state gold output.

Granite Creek Underground

Mining & Processing

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 subject to an ore sales agreement, and (iii) low-grade oxide material is placed on a segregated section of the Company's Lone Tree heap leach facility.

Mining activities for the current quarter and year ended December 31, 2025 exceeded the comparative prior-year periods. The outperformance was due to increased access to mineralized material from ongoing stope development, adjustments to mine sequencing, improving ground conditions and the delineation of additional high-grade areas through short-term drilling that were not included in the original resource model. Water inflows remained stable during the quarter and the upgraded pumping system continued to perform as expected. The construction of the water treatment plant is on track for completion near the end of the second quarter of 2026. The water treatment plant is designed to increase the capacity for surface water treatment and improve the management of water quality in preparation for ultimate discharge, supporting the Company's long-term groundwater management objectives and future operating stability.

The Company continues to encounter elevated levels of oxide mineralized material compared to levels anticipated in the March 2025 PEA at Granite Creek. The lower-grade oxide mineralized material continues to be suitable for processing via heap leach at the Company's Lone Tree heap leach facility.

During the year, the Company's stockpile of sulfide mineralized material, which is processed under a third-party toll milling agreement, reached higher than expected levels due to delays at the third-party processing facility. As at December 31, 2025, the sulfide mineralized material stockpile of over 6,500 recovered ounces of gold is expected to be processed during the first quarter of 2026.

Pre-development, evaluation, and exploration expenses were $15.4 million for the three months ended December 31, 2025 and $38.0 million for the year ended December 31, 2025, which were primarily related to underground mine development and infill drilling to upgrade mineral resources.

Infill Drilling

Infill drilling of the South Pacific Zone was initiated in June 2025 and concluded at the end of the year. These infill drilling results successfully support the geological model, confirming the continuity and high-grade nature of the deposit. The overall program included 16,000 meters drilled over 46 holes, including six additional infill holes to test and confirm continuity of mineralization. Additionally, results from seven step-out holes reinforced the Company's belief in the potential to expand mineralization in the South Pacific Zone which could ultimately expand the Project's mine life. Assay results demonstrated robust high-grade mineralization throughout the South Pacific Zone and suggest the potential to continue to expand the South Pacific Zone to the north and at depth. Results from this drill program can be found in the most recent news release dated January 20, 2026 titled, "i-80 Gold Reports New High-grade Assay Results Reinforcing Resource Expansion Potential at Granite Creek Underground Project".

This program was primarily focused on infill drilling to support the conversion of mineral resources from the inferred resource category to the indicated category to form the basis for the upcoming feasibility study and mine plan for Granite Creek underground. Results from the 2025 drill program will be combined with infill drilling data from 2023 and 2024 to produce an updated mineral resource estimate using three years of additional data and to evaluate potential production and productivity improvements as the water management improves with additional lateral extent of the mineralized zone and improved ground conditions with depth. The feasibility study is planned for completion in the second quarter of 2026.

The Company is encouraged by the operating and technical improvements at Granite Creek and continues to believe this project represents significant future value. Exploration drilling is planned in 2026 to test high potential targets and additional drilling to further delineate resources.  

Granite Creek Open Pit

Following the release of the Granite Creek open pit PEA, technical work has been underway to advance the project toward either a pre-feasibility or a feasibility level study. Simultaneously, technical trade off analyses are being conducted to optimize the project economics. Geotechnical and metallurgical drilling locations have been identified, and a study schedule is under management review. Geotechnical drilling in support of the selection of facility site locations was deferred in 2025 due to ongoing operating permit updates for the underground, pushing the start of drilling for the open pit project into 2026, and resulting in a timeline that is under review to optimize the future growth plan.

Permitting activities for the open pit expansion progressed as planned, with initial biological baseline field studies completed in the period ending December 2025. 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 permitting activities will continue in 2026 followed by commencement of baseline field studies 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 the third quarter, 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 first quarter of 2025, the Company finalized a PEA for the Ruby Hill property covering both the Archimedes underground and Mineral Point open pit.

At Archimedes underground, permitting for mining above the 5100-foot level is complete. Construction has progressed above expectations and approximately 682 meters of development has been completed during the year. Infill delineation drilling of the 426 zone of upper Archimedes commenced in the fourth quarter and initiation of infill drilling in the Ruby Deeps zone of lower Archimedes is expected to commence in the second quarter of 2026, which will form the basis of a feasibility study expected in the first quarter of 2027, approximately 12 months earlier than indicated in the PEA. Predictive groundwater models for Archimedes underground have started with construction of an additional dewatering well in the first quarter of 2026. Permitting activities below the 5100-foot elevation are underway with an estimated completion by mid-2027, while reviewing opportunities to expedite the timeline.

The timeframe for first gold mined is in the second half of 2026. The Company continues to leach the historic leach pads on the property recovering minor amounts of gold.

Capital expenditures for the year were primarily from the construction of a maintenance shop related to the Archimedes underground access portal and purchases of light equipment.

At Mineral Point open pit, the drill program that commenced in the second quarter of 2025 continued with two surface core drill rigs and completed 5,532 meters of surface core drilling during the year ended December 31, 2025. This drill program was designed to support geotechnical, metallurgical and hydrogeology studies for baseline data to advance permitting and engineering work. Mineral Point currently hosts the Company's largest gold and silver mineral resources. Due to the economic potential at Mineral Point, the Company is accelerating infill drilling and technical work to support pre-feasibility and feasibility studies. The proposed royalty financing comprising part of the Financing Package committed subsequent to December 31, 2025 contemplates $50 million available to advance these projects in 2026.

Pre-development, evaluation and exploration expenditures were $8.9 million and $18.4 million for the three and twelve months ended December 31, 2025, primarily due to increased spending at the Archimedes underground project. The higher expenditure is driven by a decline advance rate that exceeded expectations, resulting in accelerated development activity and the construction of surface infrastructure.

For the residual leaching process, management is focused on improving solution management and optimizing cyanide application rates with the objective of increasing production from the historic leach pad during the first quarter of 2026.

Cove Project

Cove is an advanced stage exploration project and is expected to be the Company's third underground mine.

National Environmental Policy Act ("NEPA") permitting activities are underway with the Bureau of Land Management ("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.

Over the last two years, the Company completed approximately 32,992 meters of infill drilling at Cove. Drilling was conducted across the Gap and Helen zones on approximately 30-meter spacing. The result of this work advanced management's understanding of the Cove project by providing a more robust geological model, a greater understanding of the gold mineralization including continuity and grade, and increased confidence in future mineral resource delineation reinforcing the potential for a high-grade underground operation. Collectively, the program has strengthened the technical foundation required for the transition from the current PEA work towards completing a feasibility study, which is planned for completion in the second quarter of 2026 and which will replace the Cove PEA filed in March 2025.

Based on this additional work, it is now anticipated that the forthcoming mineral resource estimate for Cove – to be included in the 2026 planned feasibility study – is expected to reflect a conversion of currently estimated inferred and indicated resources into higher confidence categories of resource classification. These results further validate the Company's understanding of Cove as representing a Carlin-style mineralized system with an anticipated high degree of mineral resource conversion through additional drilling.

Lone Tree Plant

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 as planned, 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.

During the fourth quarter, a Study was completed for the Lone Tree Plant refurbishment. The Study updates 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 with the 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 estimate is higher than the anticipated amount of approximately $400 million, largely due to increased costs associated with inflation and engineering design details, and additional redundancy by expanding the capacity of the filtered tailings system.

In August 2025, the Board of Directors approved a limited notice to proceed with detailed engineering to allow for the procurement of long-lead equipment and the details required for updating operating permits. 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, water pollution control, mercury abatement, and reclamation management programs for the new design remain outstanding. The Company is targeting submittal of the necessary applications for the primary environmental permits in the first quarter of 2026. Various construction activities will commence upon the approval of the associated permits.

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

Capital expenditures during the year ended December 31, 2025 and in the comparative period were primarily related to the technical work to support the refurbishment of the Lone Tree Plant.

NON-GAAP FINANCIAL PERFORMANCE MEASURES

The Company has included certain terms or performance measures 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. Non-GAAP financial performance measures do not have any standardized meaning prescribed under US GAAP, and therefore, they may not be comparable to similar measures employed by other companies. The data presented is 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 non-GAAP measure and does not constitute a measure recognized by US GAAP Accounting Standards and does not have a standardized meaning defined by US GAAP Accounting Standards. It may not be comparable to information in other gold producers' reports and filings. Management believes this non-GAAP measure improves the understanding of revenue.

"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: (loss) gain on warrants, gain (loss) on Convertible Loans, and loss on fair value measurement of Gold Prepay Agreement and Silver Purchase Agreement. Adjusted loss per share is calculated using the weighted average number of shares outstanding under the basic calculation of earnings per share.
