TORONTO

,

Nov. 12, 2025

/CNW/ -

i-80 GOLD CORP.

(TSX: IAU) (NYSE American: IAUX)

("i-80 Gold" or the "Company")

reports its

operating and financial results for the three and nine months ended

September 30, 2025

, highlighting key developments across its asset

portfolio.

"I am pleased to report the third quarter marked another period of solid execution in advancing our multi-asset development strategy in

Nevada

," stated

Richard Young

, President & Chief Executive Officer. "During the quarter, underground development advanced at Granite

Creek, construction commenced at Archimedes underground, and technical studies and permitting advanced across the portfolio. We also

continued to expand our team with high-quality local talent to support execution. With this progress, we remain on track to deliver on the key

upcoming milestones within our development plan."

Mr. Young added, "Our recapitalization strategy is also progressing well, and the support we continue to receive from lenders and other

capital providers underscores the quality of our assets and the significant value-creation opportunity ahead for i-80 Gold."

Q3 2025 OPERATING AND FINANCIAL OVERVIEW

Unless otherwise stated, all amounts referred to herein are in U.S. dollars

.

Three months ended

September 30, 2025

Revenue increased to

$32.0 million

for the quarter compared to

$11.5 million

in the prior year period, primarily driven by higher gold

ounces sold

(1)

at Granite Creek and a higher average realized gold price

(2)

.

Gold sales

(1)

for the quarter increased to 9,368 ounces at an average realized gold price

(2)

of

$3,412

per ounce compared to gold

sales

(1)

of 4,740 ounces at an average realized gold price

(2)

of

$2,441

per ounce in the prior year period.

Gross profit improved to

$3.1 million

from a gross loss of

$4.9 million

in the comparative period due to improved water management

initiatives at Granite Creek resulting in higher operational efficiencies. Gross profit for Granite Creek was near break-even for the

current quarter and is expected to be positive for the second half of 2025.

Net loss decreased to

$41.9 million

compared to

$43.1 million

in the prior year period as higher gross profit was offset by higher pre-

development, evaluation and exploration expenses as the Company advances the projects within its development plan. Upon

declaration of mineral reserves certain pre-development, evaluation, and exploration expenditures currently expensed would be

capitalized.

Loss per share of

$0.05

for the quarter compared to

$0.11

loss per share in the prior year period improved primarily due to an

increase in outstanding common shares following the equity raise in

May 2025

.

Cash used in operating activities of

$15.2 million

improved compared to

$23.5 million

in the prior year period as a result of higher gross

profit and higher working capital partially offset by increased pre-development, evaluation, and exploration expenses.

Cash balance of

$102.9 million

as at

September 30, 2025

, a decrease of

$30.8 million

compared to

June 30, 2025

, primarily due to

cash used in pre-development, evaluation, and exploration expenses and a

$11.9 million

principal repayment of the amended Orion

Mine Finance ("Orion") Gold Prepay Purchase and Sale Agreement ("Gold Prepay Agreement").

Completed approximately 53,000 feet of core drilling, including at Granite Creek underground to enhance mineral resource definition

and support a planned feasibility study, technical drilling at Mineral Point open pit within the Ruby Hill property for baseline data to

advance permitting and technical reports, and geotechnical drilling at Cove underground to also support the planned feasibility study.

Received all required permits and commenced construction for the upper level of the Archimedes project – the Company's second

planned underground mine – marking a key milestone in phase one of its development plan.

The Company remains on track to complete technical reports for its underground projects and the Lone Tree plant.

"Operationally, the third quarter was strong. Results are on plan and we remain on track to achieve full year guidance," stated

Paul

Chawrun

, Chief Operating Officer. "At Granite Creek, September marked record advance rates in the decline and excellent resource

reconciliation between grades and tonnes within the narrow Ogee Zone. Additionally, drilling in the South Pacific Zone continues to return

encouraging results. Water management has continued to progress as planned with construction of a long-term solution through the

expansion of the water treatment plant, which is on track for completion by the end of the first quarter of 2026. At Archimedes, start-up

activities and underground development are progressing very well, and the underground infill drill program within the upper zone began at

the beginning of November, as planned. Further, early indications from the ongoing feasibility work at Cove point to potentially stronger

project economics than what was in the preliminary studies filed earlier this year, which is in line with our expectations following the

additional technical work."

RECAPITALIZATION UPDATE

In parallel with advancing the development plan, the Company continues to execute on a recapitalization strategy focused on strengthening

the balance sheet and funding its development plan. During the first quarter, the Company entered into agreements to defer the

December

2024

Orion Gold Prepay Agreement and

January 2025

Silver Purchase Agreement deliveries, which were settled on

April 2, 2025

, by

entering into a gold prepay and silver purchase agreement bridge facility with National Bank with deliveries of 6,864 ounces of gold and

345,549 ounces of silver due by

September 30, 2025

. The arrangement with National Bank was settled in

May 2025

for

$32.3 million

with

proceeds from the equity raise in the second quarter.

During the second quarter of 2025, the Company closed a bought deal public offering of 345 million units at a price of

$0.50

per unit for

aggregate gross proceeds of

$172.0 million

. In addition to the offering, the Company closed a concurrent private placement of 25.2 million

units to certain directors and officers 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 was 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

. If fully exercised, the warrants

could provide the Company with up to approximately

$130 million

in additional proceeds.

The Company is actively working to secure the balance of required capital to execute the development plan and is currently in discussions

with several parties regarding a combination of additional financing options. These potential options may include debt facilities, a royalty

sale, and the potential sale of the Company's non-core FAD property. Management aims to complete the balance of its recapitalization plan

by mid-2026, aligning with the date of maturity of the Orion Convertible Loan.

As previously disclosed, approximately

$92 million

is expected to be allocated to fund construction activities, drilling, permitting, and

technical studies across all five gold projects included in the development plan, as well as the Lone Tree Plant, from

May 2025

through to

mid-2026.

OUTLOOK

The Company is on track to meet its 2025 production guidance. It expects to extract between 30,000 to 40,000 ounces

(1)(3)

of gold in

2025. Granite Creek underground is expected to contribute between 20,000 to 30,000 ounces

(1)

of gold, and the Company's two residual

heap leach operations are expected to contribute approximately 10,000 ounces of gold in 2025.

To advance development plans, three areas of growth expenditures over the next three years were outlined in the PEAs filed for all five

projects in

March 2025

. These growth expenditures fall into three categories: (i) advancing permitting activities, (ii) feasibility studies, and

(iii) development work at Archimedes underground. For 2025, the growth expenditures are expected to total between

$40 million

to

$50

million

that is primarily recognized in pre development, evaluation and exploration expenditures

(3)

.

Upcoming Catalysts

The Company's three-phase development plan prioritizes its high-grade underground refractory deposits and the refurbishment and

commissioning of its Lone Tree Plant to serve as a central autoclave and carbon-in-leach processing hub, while also progressing permitting

and technical work on its two large-scale open pit projects. In line with this plan, the Company expects to deliver the following catalysts over

the next 12 to 18 months:

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 tolling agreement entered into in

March 2025

, (ii) high-grade oxide mineralized material is

processed at a third-party plant and 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 nine months ended

September 30, 2025

exceeded the comparative prior-year periods due to

increased access to mineralized material from ongoing stope development, adjustments to the mining sequence, and improving ground

conditions in the upper Ogee Zone. Mined grades and tonnage continue to reconcile well at each level against the geological model. The

commissioning of higher-capacity underground water pumping systems during the quarter improved operational efficiency, and continues to

perform in line with expectations. The installation of a new surface groundwater well is scheduled for completion in the fourth quarter of

2025, with construction of an additional well expected to follow. The construction of the water treatment plant remains on track for

completion near the end of the first quarter of 2026, which is designed to increase treatment capacity and improve water quality

management 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

Preliminary Economic Assessment ("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 quarter, 741 ounces of low-grade oxide material from

Granite Creek were leached from the Lone Tree heap leach facility and sold.

During the quarter ended,

September 30, 2025

, the Company's stockpile of sulfide mineralized material which is processed under a third

party toll milling agreement reached a normalized level. Under the new agreement, the material is expected to be processed within 120

days of delivery to third party process facilities.

Pre-development, evaluation, and exploration expenses were $12.9 million for the three months ended September 30, 2025 and

$22

.6 million for the nine months ended September 30, 2025, which were primarily related to underground development to support the

continued ramp up and infill drilling to upgrade mineral resources.

During the three months ended

September 30, 2025

, Granite Creek achieved near break-even gross profit and it is expected to be positive

for the second half of 2025.

Infill Drilling

Infill drilling of the South Pacific Zone, initiated in

June 2025

, progressed through the quarter with two underground core drilling rigs, three

surface core rigs, and one reverse circulation ("RC") drill rig for a total of 31,136 feet of core drilling and 720 feet of RC drilling completed.

To date, 20 of the 40 holes planned over approximately 14,000 meters have been completed. Assay results from the first six holes show

robust high-grade mineralization throughout the South Pacific Zone and suggest potential to continue to expand the South Pacific Zone to

the north and at depth.

This program aims to convert mineral resources from the inferred category to the indicated category and form the basis for the upcoming

feasibility study and mine plan for Granite Creek Underground, which is planned for completion in the first quarter of 2026. The feasibility

study will incorporate an updated mineral resource estimate reflecting drill results over the past two years, including the current drill

program and will evaluate potential production and productivity improvements as the water management improves with additional lateral

extent of the orebody and improved ground conditions with depth. The Company is encouraged by the operating and technical

improvements at Granite Creek and continues to believe this project represents significant future value.

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 is delayed due to ongoing operating permit updates for the underground, pushing

the start of drilling 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 baseline field studies completed in the period ending

September

2025

. An Environmental Impact Statement ("EIS") is anticipated to be required through the Bureau of Land Management ("BLM"). Granite

Creek open pit has the potential to contribute to company-wide production by the end of the decade.

Ruby Hill Property

The Ruby Hill property includes the Archimedes underground project, for which construction began during the quarter, is expected to be the

Company's second underground mine, 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. The Company continued to recover ounces from the heap leach pads at Ruby Hill with

730 ounces of gold sold.

At Archimedes underground, permitting for mining above the 5100-foot level is complete. Construction has been progressing above

expectations and approximately, 304 feet of development has been completed as of the end of the third quarter of 2025. Drilling of the

upper 426 zone has commenced in the fourth quarter and initiation of infill drilling in the Ruby Deeps zone 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 the dewatering well

expected to start in the fourth quarter of 2025. 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 is approximately 14 months in duration from the onset of portal construction, which commenced in the third

quarter. In the interim, the Company continues to leach the historic leach pads on the property, which recovers minor amounts of gold.

At Mineral Point open pit, the drill program that commenced in the second quarter of 2025 continued with two surface core drill rigs,

completing approximately 12,410 feet of surface core drilling in the quarter to support geotechnical, metallurgical and hydrogeology studies

for baseline data to advance permitting and engineering work. Due to the economic potential at Mineral Point, the Company is evaluating

opportunities to accelerate infill drilling and technical work to support pre-feasibility and feasibility studies, subject to sufficient capital

funding.

Pre-development, evaluation and exploration expenditures of

$4

.4 million and

$9

.5 million during the current three and nine month periods,

respectively, were related to preparatory work related to portal development and other surface work at Archimedes as well as costs

associated with the technical drill program for Mineral Point open pit.

The construction of surface infrastructure, such as a maintenance shop and offices, to support the Archimedes underground portal is

complete. Utilities such as water, power and compressed air are in place, and the highwall around the portals has been secured.

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. Cove is

expected to be the Company's third underground mine and begin contributing to company-wide production in mid-2029.

Over the last two years, the Company completed approximately 45,000 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 our 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 the first 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.

During the quarter, a geotechnical logging campaign commenced with two rigs with a total of 8,598 feet of a planned 17,900 feet drilled to

date.

Lone Tree Plant

The Lone Tree plant (the "Plant") is currently non-operational and a construction decision on its refurbishment, subject to an engineering

study, is expected in the second quarter of 2026. Processing infrastructure at Lone Tree includes an autoclave, carbon-in-leach mill,

flotation mill, heap leach facility, assay lab and gold refinery, tailings dam, waste dumps and several buildings, including a warehouse,

maintenance shop and administration building.

The Plant has one of three autoclave facilities in

Nevada

, the other two autoclaves being owned by Nevada Gold Mines Inc., a joint venture

between Barrick Mining and Newmont Gold Corporation, and is a strategic asset in unlocking value from i-80 Gold's three underground

deposits once refurbished and commissioned as anticipated, by providing an owner-operated processing facility for the Company's high-

grade underground refractory material.

A feasibility-level Class 3 engineering study is nearing completion to refurbish the Plant. The refurbishment 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.

The Plant is envisioned to process refractory mineralized material through the autoclave, as well as oxidized material through the carbon-in-

leach ("CIL") from the Company's three underground mines, Granite Creek, Archimedes and Cove, creating a regional hub-and-spoke

mining and processing strategy. The Company has placed key positions for the initial construction execution, early works planning, and the

procurement and engineering of long lead equipment.

The Plant is permitted for the existing operational components in use. The approval of new and revised permit applications pertaining to air

quality, water pollution, mercury abatement, and reclamation management programs for the new Plant design remain outstanding. The

Company is on track to submit the necessary applications for the environmental permits in the fourth quarter of 2025. Various construction

activities will commence upon the approval of the associated permits.

In

August 2025

, the Board of Directors approved a limited notice to proceed to begin detailed engineering to allow for the procurement of

long-lead equipment and to support the submission process for updating permits during the fourth quarter. A construction decision is

expected in the second quarter of 2026.

During the third quarter,1,313 ounces of gold were sold from the Lone Tree leach pads. The leaching of the historic leach pad at Lone Tree

continues to produce gold at profitable quantities. The Company plans to continue to recover ounces from the Lone Tree leach pads as long

as it is economical to do so.

Capital expenditures during the three and nine months ended

September 30, 2025

and in the comparative period were primarily related to

the technical work on the refurbishment of the autoclave processing 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, (loss) gain 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.
