i-80 Gold Announces Best Results To-Date from Underground Drilling at Cove

New Helen Zone Results (3 Holes) Include 22.6 g/t Au over 19.1 m, 32.9 g/t Au over 14.9 m and 23.5 g/t Au over 12.8 m

RENO, March 5, 2024 - i-80 Gold Corp. (TSX: IAU) (NYSE: IAUX) ("i-80", or the "Company") is pleased to announce additional results from 2023 drilling in the Helen Zone that include some of the best results received to-date from the underground drilling program at the Company's 100%-owned McCoy?Cove Property ("Cove" or "the Property") located in Lander County, Nevada.

The new results are from results that continue to be received from drilling completed in 2023 to define the Helen Zone, the first horizon expected to be accessed at the Cove Mine. The program is confirming high?grade mineralization over appreciable thickness including multiple lenses in some parts of the deposit (see Figure 2). The most recently received results from the Helen Zone contain some of the best results received to-date from the underground program and compare favourably with initial results from the Gap Zone where previously released results included intercepts of up to 12.9 g/t Au over 36.1 m in hole iCHU23?04, 14.9 g/t Au over 32.7 m in hole iCHU23-10 and 18.9 g/t Au over 29.3 m in hole iCHU23-11. A complete summary of new results is provided in Table 1.

Highlight new results from drilling at McCoy-Cove include:

Helen Zone

• iCHU23-37: 14.4 g/t Au over 9.1 m

And 22.6 g/t Au over 19.1 m
And 55.0 g/t Au over 1.8 m

• iCHU23-38: 13.8 g/t Au over 10.1 m

And 32.9 g/t Au over 14.9 m

• iCHU23-39: 25.3 g/t Au over 9.4 m

And 30.5 g/t Au over 2.1 m
And 19.7 g/t Au over 2.7 m
And 23.5 g/t Au over 12.8 m

"Results received to-date have met or exceeded our expectations as definition drilling continues to confirm that Cove is one of the highest-grade, development-stage, gold deposits in North America.", stated Tyler Hill, Chief Geologist of i-80 Gold. "Deposits with grades in excess of ten grams per tonne gold over widths frequently in excess of ten metres are rare. Significant upside exists at McCoy-Cove as mineralization in the main deposit remains open for expansion and multiple high-potential exploration targets have been identified on the large land package."

The McCoy-Cove Property is strategically located in the prolific Battle Mountain Trend immediately south of Nevada Gold Mines' Phoenix Mine and within 83 km (by road) of the Company's Lone Tree processing facility (see Figure 1). Cove is one of three projects being advanced to realize the Company's goal of becoming one of the largest producers in the United States.

The underground drill program at Cove is expected to consist of more than 40,000 m of drilling on approximate 30 metre spacing focused on the CSD Gap and Helen Zone portions of the deposit while mineralization below the pit in the Cove South Deep and 2201 zones are not being drilled as part of this program (Figure 3) but offer a significant upside opportunity.

Carlin-style mineralization in the Helen and CSD Gap zones is hosted primarily in the Favret limestone rock unit with enhanced grades and thicknesses of mineralized zones occurring at structural intersections, along the margins of dikes and sills, and within the axis of the northwest striking Cove anticline.

Table 1 - Highlight New Assay Results from Cove Underground Drilling

The McCoy-Cove Property comprises a large package of approximately 13,000 hectares covering an area roughly 15 km by 10 km that offers substantial exploration upside as the bulk of work completed to-date has been focused on the main deposit areas. Earlier exploration, mostly completed in 20214, resulted in several new discoveries that have received little to no follow-up including polymetallic mineralization in the 2201 and Davenport targets. One of the primary future targets at McCoy-Cove is the pediment area to the east of the Cove deposit where only two holes have drilled to a sufficient depth to intersect the favourable Favret limestone unit. Both holes intersected broad zones of Carlin-type alteration with assays of up to 1.7 g/t Au and 364 g/t Ag over 11.4 m proximal to an interpreted large untested structural trend that represents a major future exploration target.
