Company Announcements

TORONTO , May 12, 2026 /PRNewswire/ - i-80 GOLD CORP.(NYSE: IAUX) (TSX: IAU) ("i-80 Gold" or the "Company") reports its financial and operating results, as well as development highlights, for the first quarter and three months ended March 31, 2026.

"i-80 Gold is off to a strong start in 2026, advancing our growth strategy to create a Nevada based mid-tier gold producer while completing a transformational recapitalization during the first quarter that fully funds our current development plan,⁽¹⁾" stated Richard Young, President & CEO. "The financing packages executed in the first quarter significantly strengthen i-80 Gold's balance sheet and materially derisk execution of the development plan. Following the recapitalization, we approved a key construction decision related to the autoclave refurbishment, a cornerstone asset within our planned hub and spoke plan to develop our underground deposits within phase one of our development plan, which is targeting 150,000 to 200,000 ounces of gold beginning in 2028⁽¹⁾. Further, we initiated the 2026 drill program, representing the largest program in the Company's history in terms of planned footage and budget, supporting resource and reserve development in preparation of pre-feasibility and feasibility studies. In parallel, the business delivered its highest quarterly gross profit to date, supported by higher gold output and a higher realized gold price. We also continued to attract quality talent across the Company and at the Board level, further strengthening our ability to execute on our business plan."

FIRST QUARTER FINANCIAL, OPERATING AND DEVELOPMENT HIGHLIGHTS
Three months ended March 31, 2026 compared to three months ended March 31, 2025
Unless otherwise stated, all amounts referred to herein are in U.S. dollars.

• Revenue increased to $52.4 million, representing 10,590 ounces in gold sold⁽²⁾ at an average realized gold price⁽³⁾ of $4,941 per ounce, compared to $14.0 million represented by 4,952 ounces sold⁽²⁾ at an average realized gold price⁽³⁾ 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⁽³⁾.

• 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.

• 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 closed several financing transactions for a total amount of $787.5 million. Gross proceeds of $662.5 million and net proceeds of $637.2 million were received on closing. These financing arrangements completed the recapitalization plan ahead of the Company's mid-2026 target and established a fully funded development plan⁽¹⁾:

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

RECAPITALIZATION PLAN COMPLETE

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⁽⁴⁾ 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. 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. The anticipated increase in annual gold output from approximately 50,000 ounces in 2026 to a range of 300,000 to 400,000 ounces upon completion of Phase 2 is expected to generate sufficient operating cash flow to fund Phase 3, which currently includes the development of the Mineral Point open pit oxide project and an anticipated average annual gold output of 600,000 ounces.⁽¹⁾ 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.

2026 Guidance

The Company remains on track to meet its 2026 guidance as originally published in its 2025 Year End Annual Report on Form 10K published on February 19, 2026.

OPERATIONAL AND FINANCIAL OVERVIEW

Paul Chawrun, Chief Operating Officer, commented: "We are very pleased with the development progress achieved during the first quarter at our two underground projects. At Granite Creek, progress on the main decline and waste development remains on plan, and gold output has reached a steady operating rate, while water ingress continues to be effectively managed with existing infrastructure. Commissioning of a second, larger water treatment plant is on track for next month, which is expected to further simplify day-to-day operations for the long term. At Archimedes, both the development ramp and exploration drift are advancing ahead of plan, supported by favorable ground conditions and strong execution by our team and contractors. This work remains a priority to support infill drilling and technical work for the feasibility study, targeting for completion late in the first quarter of 2027, pending the potential expansion of the current drill program.

Drill results released in the first quarter at both Granite Creek South Pacific Zone and Upper Archimedes at Ruby Hill continued to return consistent and positive results, highlighting high-grade intercepts, continuity of mineralization, and further expansion potential at both deposits. At Mineral Point, we initiated a significant drill program to support a pre-feasibility study anticipated for completion in 2027. 

The Lone Tree Plant refurbishment timeline and costs remain on track. We look forward to commencing demolition and site early works activities this quarter with the mobilization of Hatch's construction team, while in parallel, procurement and detailed engineering remain on track for first gold pour in December 2027."

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.

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 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.

Drill Program

During the quarter, 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 preliminary economic assessment ("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 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

During the first quarter of 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

At Mineral Point, 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 Underground

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

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.

During the first quarter, the Company provided Hatch with a formal Notice to Proceed 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 $30.5 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 the installation of lighting and electrical replacement and upgrades. Capital expenditures for the three months ended March 31, 2026 were primarily related to refurbishment activities.

The facility 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.
