**i-80 Gold Reports New High-Grade Assay Results Reinforcing** 

**Resource Expansion Potential at Granite Creek Underground Project** 

**TORONTO, ON, January 20, 2026 – i-80 GOLD CORP. (TSX:IAU) (NYSE American:IAUX) ("i-80 Gold", or the "Company")** is pleased to announce assay results from its 2025 drilling campaign at the Granite Creek Underground Project ("Granite Creek Underground" or the "Project"). New assay results from 40 holes continue to demonstrate robust high-grade mineralization throughout the South Pacific Zone (the "SPZ") confirming expansion of the mineralized envelope and potential for mineral resource expansion to the north and at depth (see Figures 1 and 2 in Appendix).

The Project is i-80 Gold's first underground gold operation and ramp-up activities continue to advance toward steady-state gold output. The Company is currently mining the top of the southern portion of the SPZ. As of December 31, 2024, Granite Creek Underground hosted a measured and indicated gold mineral resource estimate of 261,000 ounces at 10.5 grams per tonne and an inferred gold mineral resource of 326,000 ounces at 13.0 grams per tonne. Granite Creek Underground is located along the prolific Getchell Trend in northern Nevada, approximately 10 kilometers south of Nevada Gold Mines' Turquoise Ridge Complex, which currently hosts an estimated 18 million ounces of measured and indicated gold mineral resources and 2.5 million ounces of inferred gold mineral resources <sup>(1)</sup> (see Figure 3 in Appendix).

A total of 16,000 meters were drilled over 46 holes as part of the 2025 drilling program at Granite Creek Underground, which began in June 2025 and concluded in December 2025. The overall program included an additional six infill holes relative to the original plan to test and confirm continuity of mineralization ahead of the planned feasibility study. The results of seven step-out holes, as part of the overall program, reinforced the Company's belief in the potential to expand mineralization at SPZ and ultimately extend the Project's mine life. The most recent assay results are provided in Table 1 below and include the first six holes announced in a press release on September 10, 2025<sup>(2)</sup> (to view the announcement, <u>click here</u>).

**Highlight results from infill holes in 2025 drilling at the SPZ** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **40.4 g/t Au over 13.2 m in hole iGU25-31** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **31.3 g/t Au over 7.8 m in hole iGU25-15** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **15.0 g/t Au over 17.5 m in hole iGU25-24** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **12.8 g/t Au over 19.8 m in hole iGU25-08** 

"The 2025 infill drilling results at Granite Creek Underground successfully support our geological model, confirming the continuity and high-grade nature of the deposit. The South Pacific Zone remains open to the north and at depth and will continue to be tested through additional drilling in the coming years," stated Tyler Hill, Vice President Geology. "The drill program was a key step in advancing the upcoming Granite Creek Underground feasibility study. Importantly, these drill results reinforce our view that similar success could be achieved with the planned 2026 drill programs at Archimedes underground and Mineral Point open pit on the Ruby Hill property. This confidence is supported by comparable results from our Cove underground project, which shares a similar structural framework and sedimentary rock-hosted disseminated mineralization present within each of these projects."

The 2025 drill program was primarily focused on infill drilling to support the conversion of mineral resources from the inferred mineral resource category to the Indicated category. Seven holes also tested the expansion potential of the SPZ to the north and at depth. 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. This mineral resource estimate will form the basis of the upcoming Granite Creek Underground feasibility study, which is expected to be completed late in the first quarter of 2026, with results to be released in the second quarter of 2026. The current mineral resource estimate in the PEA filed in March 2025 did not include data from drilling conducted in 2023 and 2024. The Company filed results from a preliminary economic assessment on Granite Creek Underground in March 2025 (the "PEA") outlining an approximate 8-year mine life with an average annual gold production of approximately 60,000 ounces, following production ramp up<sup>(3)</sup> (to view the announcement, click here).

The Company is currently evaluating the timing of an additional step out and infill drilling campaign for the SPZ in 2026 as part of a multi-year drill program.

**Cautionary Statement Regarding Forward Looking Information** 

Certain information set forth in this press release, including but not limited to management's assessment of the Company's future plans and operations, expectations regarding the timing, execution and results of the Company's drilling programs, outlook on gold output, the anticipated timing of gold output, project development or technical studies, including completion of the anticipated Granite Creek Underground feasibility study and the release of its results, the potential for mineral resource conversion and opportunities for expansion to the north and at depth at the SPZ, and management's view that similar mineral resource conversion and expansion success could be achieved with the planned 2026 drill program at Archimedes Underground and Mineral Point open pit projects on the Ruby Hill property, and Granite Creek Underground achieving ramp up to a steady state of gold output constitute forward looking statements or forward-looking information within the meaning of applicable securities laws. All statements other than statements of historical fact are forward-looking statements. Often, but not always, forward-looking statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "continues", "forecasts", "projects", "predicts", "intends", "anticipates" or "believes", or variations of, or the negatives of, such words and phrases, or state that certain actions, events or results "may", "could", "would", "should", "might" or "will" be taken, occur or be achieved. Readers are cautioned that the assumptions used in the preparation of information, although considered reasonable at the time of preparation, may prove to be inaccurate and, as such, reliance should not be placed on forward-looking statements. The Company's actual results, performance or achievement could differ materially from those expressed in, or implied by, these forward-looking statements and, accordingly, no assurance can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what benefits, if any, that the Company will derive therefrom. By their nature, forward looking statements are subject to numerous risks and uncertainties, some of which are beyond the Company's control, including general economic and industry conditions, volatility of commodity prices, title risks and uncertainties, uncertainty in geological, metallurgical and geotechnical studies and opinions, and ability to access sufficient capital from internal and external sources such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. The Company's ability to refinance its indebtedness will depend on the capital markets and its financial condition at such time, currency fluctuations, construction and operational risks, licensing and permit requirements, environmental risks, competition from other industry participants, the lack of availability of qualified personnel or management, imprecision of mineral resource, or production estimates.

This release also contains references to estimates of mineral resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation (including estimated future production from the Project, the anticipated tonnages and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may have to be re-estimated based on: (i) fluctuations in commodities prices; (ii) results of drilling, (iii) metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation

Readers are encouraged to carefully review these risk factors as well as the Company's other filings with the U.S. Securities and Exchange Commission and the Canadian Securities Administrators. All forward-looking statements contained in this press release speak only as of the date of this press release or as of the dates specified in such statements. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise except as required by applicable law.
