i-80 Gold Releases High-Grade Results from Underground Drilling at Granite Creek

Including 22.0 g/t Au over 29.0 m, 18.4 g/t Au over 14.4 m & 60.5 g/t Au over 4.1 m

RENO, May 14, 2024 - i-80 Gold Corp. (TSX: IAU) (NYSE: IAUX) ("i-80", or the "Company") is pleased to announce additional high-grade results from the ongoing drill program to define mineralization in the upper part of the South Pacific Zone at the Company's Granite Creek Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada.

The new results are from seven new holes drilled in the underground campaign focused on the delineation of mineralization within the South Pacific Zone ("SPZ"). The SPZ is located immediately north of the current mine workings and is expected to become the primary zone for mining (see Figure 1). Initial stopes in the SPZ are being planned for H1-2024 once mine workings are extended to provide access.

The underground drill program is focused on the southern and upper part of the deposit, where initial mining is planned. Results from the underground program continue to demonstrate continuity of high-grade mineralization with some of the best results received to-date in the South Pacific Zone.

Highlight results from the most recent seven new underground drill holes testing the South Pacific Zone at Granite Creek include:

• GCPU23-33: 17.7 g/t Au over 7.0 m
• GCPU23-45A: 27.2 g/t Au over 4.0 m
• GCPU24-01: 18.1 g/t Au over 14.4 m
• GCPU24-02: 22.0 g/t Au over 29.0 m
• GCPU24-04: 11.0 g/t Au over 22.4 m
• GCPU24-04: 60.5 g/t Au over 4.1 m

"The ongoing surface and underground drilling program at Granite Creek continues to confirm impressive high-grade gold mineralization, including over substantial widths.", stated Tyler Hill, Chief Geologist of i‑80. "Importantly, the South Pacific Zone is expected to become the primarily source of mineralization at Granite Creek and remains open along strike to the north and at depth, providing considerable upside."

With its improved financial position, the Company is in the process of ramping up a large-scale surface drill program to complete further definition and expansion drilling of the SPZ in advance of an updated resource estimate and Feasibility Study for the Granite Creek Property. Four (4) drill rigs will be used to complete this program. Additionally, the main decline is being extended to provide access to the SPZ and initial stoping of this new zone is expected mid-year.

The Granite Creek Property is strategically located proximal to Nevada Gold Mines' Turquoise Ridge and Twin Creeks mines at the north end of the Battle Mountain-Eureka Trend, at its intersection with the Getchell gold belt in Nevada (see Figure 2). High-grade mineralization occurs in a near-identical geological setting as that at the multi-million ounce Turquoise Ridge Mine located immediately to the north; proximal to a major regional fault (the Getchell or Range Front fault) on the eastern edge of the large Osgood Mountains intrusive complex. The Granite Creek deposit remains open at depth and along strike.

The Company will hold an "Investor Day" presentation immediately following its Annual General Meeting (AGM) today, May 14, 2024, being held at Bennett Jones LLP office - 100 King St W Suite 3400, Toronto in the Canada Boardroom on the 34th floor. The in‑person AGM will begin at 4:00pm EST followed by the webcasted Investor Day presentation commencing at 4:30pm EST. The presentation can also be accessed via a conference call and webcast (details below). Investors are invited to attend the event in‑person where they can meet and discuss details with members of i-80's Board of Directors and Management Team.
