SECOND QUARTER HIGHLIGHTS

Three months ended June 30, 2026 compared to three months ended June 30, 2025.
Unless otherwise stated, all amounts referred to herein are in U.S. dollars.

Development

•Granite Creek underground development continued ahead of plan increasing access to high-grade headings supporting the ongoing ramp up. The project remains on track to achieve its full-year production guidance, with a published feasibility study anticipated in the third quarter of 2026.

•Archimedes underground advanced on schedule and largely on budget with the main decline development on track, advancement of the exploration drift, which has since been completed, and commencement of the ventilation raise in preparation for first gold mined by year-end.

•Lone Tree Plant refurbishment advanced on schedule and on budget as early works and pre-construction readiness activities continued during the quarter, and the commencement of demolition mid-June ahead of major construction. Procurement activities remain on schedule, with approximately 50% of procurement packages, by value, awarded as of mid-July. Project capital remains on budget with minimal contingency drawdown and approximately 40% of capital committed as of mid-July.

•Completed approximately 19,000 meters of drilling across three projects, including infill drilling at Archimedes underground and Mineral Point open pit in support of planned 2027 technical studies for both projects, as well as resource definition drilling at Granite Creek underground beyond the area covered by the upcoming feasibility study.

•Permitting largely on track across the development plan as permitting actions continued to advance across the portfolio.

Financial and Operating

•Revenues were $24.3 million, representing 5,335 ounces in gold sold(2) at an average realized gold price(1) of $4,522 per ounce, compared to $27.8 million represented by 8,400 ounces at an average realized gold price(1) of $3,301 per ounce in the prior year period. The decrease in revenues was primarily driven by lower gold sold at Granite Creek as a result of delays at the third-party processing facility, partially offset by a higher average realized gold price(1). Revenues in the prior year quarter were higher due to the finalization of the third-party toll processing agreement in March 2025 and the processing of a higher volume of stockpile material.

•Gold production increased to 11,098 ounces from 4,178 ounces in the prior year period. The Company remains on track to achieve its full year production guidance range.

•Gross profit increased to $8.6 million from $0.8 million in the prior year period due to a higher realized gold price.

•Net loss increased to $52.5 million compared to $30.2 million in the prior year period, due primarily to higher pre-development, evaluation and exploration costs incurred as the Company advances multiple projects within its development plan. The higher costs were related to drilling programs at the Ruby Hill property. Upon declaration of mineral reserves, certain pre-development, evaluation and exploration expenditures that are currently expensed will be capitalized.

•Net loss per share increased to $0.06 compared to a $0.05 loss in the prior year period, primarily due to a higher net loss, partially offset by an increase in the weighted average number of common shares outstanding following the equity financing in May 2025.

•Adjusted net loss(1) increased to $41.2 million compared to $26.5 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 $49.6 million compared to $11.3 million in the prior year period as a result of comparative working capital changes of $20.9 million primarily as a result of increased inventory due to third-party processing availability and higher pre-development, evaluation and exploration expenses which was partially offset by higher gross profit.

•Cash and cash equivalents were $464.6 million as of June 30, 2026, a decrease of $49.0 million compared to March 31, 2026, primarily due to cash used in operations of $49.6 million, capital expenditures of $21.5 million primarily driven by the start of the Lone Tree Plant refurbishment project partially offset by a release of restricted cash of $16.9 million and proceeds from warrant exercises.

Sustainability

•Advanced community engagement across Northern Nevada by progressing community development, workforce development, and grant funding initiatives, including a joint $300,000 donation with Franco-Nevada Corporation to support development of the first licensed childcare facility in Eureka County, neighboring the Company's Ruby Hill property.

•Strengthened Board with the appointment of Stephen Gottesfeld at the annual general meeting, bringing nearly 30 years of global mining experience in environmental, sustainability, legal and governance matters across the mine lifecycle.

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 and low-grade oxide mineralized material is subject to an ore sales agreement. Low-grade oxide mineralized material was sold under the ore purchase beginning in the first quarter of 2026, and (iii) residual leaching of low-grade oxide material previously placed on a segregated section of the Company's Lone Tree heap leach facility continues with no additional mineralized material being placed after the first quarter of 2026.

During the quarter, mining activities at Granite Creek were impacted by ground conditions in two of the mine highest-grade headings, which temporarily restricted access to high-grade mineralized material and deferred a portion of planned high-grade tonnes during the quarter. Remediation of the affected headings was completed and access was re-established late in the quarter, allowing these areas to contribute to production beginning in the third quarter.

Throughout the quarter, advancement of the main decline as well as horizontal development continued to progress ahead of the mine plan, with year-to-date development footage exceeding plan. As a result, the number of available high grade mineralized material headings has increased significantly throughout the quarter. The Company remains on track to meet its full-year production guidance.

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. Work on an enhanced pumping system, that includes expanded sumps at lower levels and higher-capacity pumps, advanced during the quarter. Pumps were sized and ordered with installation continuing throughout the remainder of the year to increase overall water discharge capacity as the mine progresses at depth. Further, initial phases of commissioning a second water treatment plant began in late July, with mechanical completion having recently been completed. The second water treatment plant will increase surface water treatment capacity to approximately 3,500 gallons per minute to support the Company's long-term groundwater management objectives.

At June 30, 2026, the Company had in-process material containing over 5,300 recoverable ounces at its third-party processing facility. The Company expects the material to be processed during the third quarter of 2026. Approximately 1,800 ounces of gold was also held in inventory at June 30, 2026. Gold ounces sold were lower than the prior year periods due to availability at the third-party processing facility.

Processing cost per unit has increased compared to the prior year periods due to a higher proportion of sulfide material being processed at the third-party processing facility.

During the three months ended and six months ended June 30, 2026, growth capital expenditures were primarily related to the water treatment plant project. Sustaining capital expenditures were related primarily to the electrical substation replacement.

Pre-development, evaluation, and exploration expenses were $7.9 million for the three months ended June 30, 2026, which were related to underground mine development and infill drilling to upgrade mineral resources and step-out drilling.

Drill Program

During the quarter, the Company continued infill and step-out drilling at Granite Creek. The underground drill program remained focused on infill drilling to support resource conversion and mine planning. Drilling progressed slower than anticipated during the quarter due to water management, maintenance downtime, and rig relocation. The updated mineral resource estimate is near completion and under internal review. The feasibility study is now expected to be completed in the third quarter of 2026.

Granite Creek Open Pit

Preparation for a pre-feasibility trade-off study has commenced following the completion of the Granite Creek open pit preliminary economic assessment, prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the corresponding Initial Assessment prepared under Subpart 1300 of Regulation S-K ("S-K 1300"), each filed on March 31, 2025 ("PEA"). 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 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.

The Company continues to leach the historic leach pads on the Ruby Hill property, recovering gold. Year-to-date gold production from the historic leach pad remained below expectation as infiltration on the pad remained challenging. Higher processing cost per ounce compared to the prior year periods was due to lower produced ounces. For the residual leaching process, management continues to focus on managing ponding, maximizing the area under leach, and optimizing cyanide application rates.

Archimedes Underground

During the quarter, underground development at the Archimedes project continued to advance on schedule, with 899 meters of development completed during the quarter, supported by favorable ground conditions and high productivity rates from contractors. Pump testing was conducted on a recently completed dewatering well, and permitting activities for below the 5,100-foot level continued to advance as planned. The planned start of mining above the 5,100-foot level is fully supported by existing permits and is not dependent on the timing or outcome of permitting activities below the 5,100-foot level. The Company continues to expect to achieve first gold from Archimedes in the fourth quarter of 2026.

Growth capital expenditures for the three and six months ended June 30, 2026 were primarily related to heavy mobile equipment, infrastructure upgrades, power upgrades and mine load centers for the underground.

Pre-development, evaluation and exploration expenditures were $20.1 million and $32.5 million for the three and six months ended June 30, 2026. $20.1 million and $32.5 million for the three and six months ended June 30, 2026. Pre-development, evaluation and exploration expenditure were higher than the prior year periods primarily due to underground development at the Archimedes underground project which began in the third quarter of 2025. Development during the quarter focused on completion of the exploration drift to establish drilling platforms to access the ongoing definition drilling program for the Ruby Deeps zones at depth. Further development included commencement of the first ventilation raise.

Drilling activities during the quarter included the completion of the 2025-2026 program in the upper 426 zone and commencement of the 2026 infill drill program with 3,124 meters of infill drilling completed in the lower 426 and Ruby Deeps zones in support of a feasibility study. The latest assay results from the 2025-2026 drill program were published during the second quarter in a press release dated June 25, 2026. The results continued to confirm high-grade mineralization, demonstrate continuity within the planned mining areas, and extend mineralization beyond the boundaries of the current mineral resource estimate supporting the 2025 PEA. Drilling also continued to intersect significant intervals of oxide mineralization not included in the current mineral resource estimate.

An infill drilling program largely within the lower portion of the 426 zone and Ruby Deeps zone commenced in the second quarter of 2026, targeting approximately 55,000 meters planned across 140 drill holes in support of the planned Archimedes Feasibility Study. The drill program is encountering slower than planned progress due to contractor staffing availability. As a result, the Archimedes feasibility study is now anticipated to be completed approximately mid-year 2027.

Mineral Point Open Pit

At Mineral Point open pit, the Company advanced its surface drill program during the quarter as part of the largest 12-month drill program in the Company's history, completing approximately 14,836 meters of core drilling and reverse circulation drilling with a fleet of up to five drill rigs, primarily for infill drilling of the currently classified inferred resources. The drill program encountered slower than planned progress due to drill rig and contractor staffing availability, as well as slower penetration rates than expected in the sanded dolomite unit. Management expects to increase the overall drilling rate for the remainder of the year with mobilization of additional rigs, however, completion of the drill program is now expected in the first quarter of 2027. The results from this program will support a pre-feasibility study, which is expected at approximately mid-year 2027, pending timing of the drilling program. Early-stage pre-permitting activities continued to progress during the quarter.

8

Cove Underground

Cove is an advanced stage exploration project and is expected to be the Company's third underground mine. During the second quarter, the Company continued to advance technical and economic studies for the Cove Underground project. Various baseline studies and agency comment responses were submitted to the BLM. In addition, water pollution control permit renewal and modification applications were submitted to NDEP-BMRR for the underground mine and rapid infiltration basins. Additional federal and state permitting actions continue to progress. A feasibility study for Cove is expected to be completed in the third quarter of 2026.

Lone Tree Plant Refurbishment

The Lone Tree Plant (the "Plant") is currently undergoing refurbishment following a positive construction decision in 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 Plant is envisioned to process material from the Company's three underground mines, Granite Creek, Archimedes, and in the future Cove, to establish a regional hub-and-spoke mining and processing model. Upon refurbishment and commissioning, the 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 quarter, detailed engineering and procurement advanced with the Company's contractor, with procurement package preparation and long-lead item ordering a key focus. Cleaning and environmental testing of the existing tanks, containment, and piping was completed, and demolition of existing infrastructure commenced during the quarter. The Company also progressed the tailings storage facility and new filtered tailings design work. The refurbishment timing remains on track with the engineering study timeline and scope of work. Early works and pre-construction readiness activities are well underway on site and continue to advance on schedule ahead of major construction, which is expected to commence in the fourth quarter of 2026. Second and third quarter pre-construction activities include mobilization of the EPCM contractor to site, commencement of demolition of the existing plant components requiring replacement as part of the refurbishment and advancement of detailed engineering, procurement packages, and the award of key contracts.

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, as planned, with several permits received to date and further permits pending. Various construction activities are scheduled to commence in the second half of 2026 upon the anticipated approval of the associated permits, with major construction activities anticipated to commence in the fourth quarter of 2026.The permitting process is currently on track and aligns with the construction schedule.

Capital expenditures for the three months and six months ended June 30, 2026 were primarily related to the refurbishment of the Lone Tree Plant. The project spend is weighted in the second half of the year and the Company expects to meet full-year guidance.

As of June 30, 2026, total construction commitments were $110.1 million with approximately 30% of the project cost committed. Subsequent to the quarter, procurement activities remain on schedule, with approximately 50% of procurement packages, by value, awarded as of mid-July. Project capital remains on budget with minimal contingency drawdown and approximately 40% of capital committed as of mid-July.
