i-80 Gold Corp.

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).

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

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

3 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.

During the three months ended March 31, 2026, the Company continued to advance the feasibility study for the Cove Underground project, which is expected to be completed in the second quarter of 2026. Further, the Company also submitted updated hydrological and geochemical baseline reports to the BLM. During the second quarter, the Company submitted the updated biological baseline studies report, as well as the Plan of Operations amendment to the BLM.

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.

Pre-development, evaluation and exploration expenses

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.

Other expense

Losses and gains on Silver Purchase Agreement, NSR Royalty, 2026 Gold Prepay derivative represents fair value revaluation driven by changes in the gold and silver forecast prices during the period.

The loss on convertible loans derivative represents the fair value measurement changes related to the conversion feature.

Finance fee expense relates primarily to origination costs for the NSR Royalty as well as other general financing arrangement costs not allocable to the financing transactions that closed during the first quarter of March 31, 2026.

Interest Expense

Interest expense for the three months ended March 31, 2026 was $6.2 million, a decrease of $2.0 million compared to the prior year quarter. The decreased interest expense was primarily related to Orion Gold Prepay interest as a result of settlements.

Loss on loan extinguishment

Loss on loan extinguishment related to the Convertible Debentures, Orion Gold Prepay and Orion Convertible Loan were recognized on the settlement of these debt instruments prior to maturity as well as for the convertible debentures related to the premium paid.
