i-80 Gold Intersects High-Grade Gold in Granite Creek Underground Drill Program

Including 28.2 g/t Au over 17.8 m, 39.0 g/t Au over 9.5 m & 20.1 g/t Au over 21.1 m

RENO, Nov. 1, 2022 - i-80 Gold Corp. (TSX: IAU) (NYSE: IAUX) ("i-80", or the "Company") is pleased to announce additional high-grade results from the 2022 underground drill program at the Company's Granite Creek Property ("Granite Creek" or the "Property") located in Humboldt County, Nevada.

A primary target of the 2022 program was to perform delineation and expansion drilling of the Ogee Zone, expected to provide the bulk of mineralization to be mined in the next twelve months. This drilling focused on the area between the bottom level of the mine workings and the deepest hole drilled by i-80 to date, designed to test the Ogee Zone depth extension of iGS21-15, which intersected multiple high-grade mineralized horizons, including 13.3 g/t Au over 13.1 m, 20.3 g/t Au over 7.5 m and 10.1 g/t Au over 17.5 m (See Figure 1).

Highlight results from new underground drilling at Granite Creek include:

• 10.7 g/t Au over 7.0 m (0.31 oz/ton Au over 23.0 ft) - iGU22-43B
• 28.2 g/t Au over 17.8 m (0.82 oz/ton Au over 58.3 ft) - iGU22-47
• 16.3 g/t Au over 7.6 m (0.48 oz/ton Au over 25.0 ft) - iGU22-50
• 49.0 g/t Au over 1.1 m (1.41 oz/ton Au over 3.6 ft) & 65.4 g/t Au over 1.6 m (1.91 oz/ton Au over 5.3 ft) - iGU22-51
• 39.0 g/t Au over 9.5 m (1.14 oz/ton Au over 31.1 ft) & 11.9 g/t Au over 2.7 m (0.35 oz/ton Au over 8.7 ft) - iGU22-52
• 20.1 g/t Au over 21.1 m (0.59 oz/ton Au over 69.3 ft) & 23.2 g/t Au over 4.7 m (0.68 oz/ton Au over 15.3 ft) - iGU22-53

Multiple levels have been developed on the Ogee Zone and the Company continues extend of the decline to depth, with the goal of initiating access to the new South Pacific Zone that is located immediately below and to the north of the underground mine workings.

"Drilling in the Ogee Zone continues to intercept impressive high-grade mineralization over substantial widths", stated Tyler Hill, Senior Geologist of i-80. "Results so far have demonstrated that the Ogee Zone is comprised primarily of oxide mineralization, amenable to non-refractory processing. The Ogee and South Pacific Zones remain open at depth, providing substantial upside."

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 from the existing underground workings.

All samples were submitted to either American Assay Laboratories (AAL) or ALS Minerals (ALS) both of Sparks, NV, which are ISO 9001 and 17025 certified and accredited laboratories, independent of the Company. Samples submitted through AAL and ALS are run through standard prep methods and analysed using FA-Pb30-ICP (Au; 30g fire assay; AAL) and Au-AA23 (Au; 30g fire assay; ALS) and ME-ICP41 (35 element suite; 0.5g Aqua Regia/ICP-AES; ALS). AAL and ALS also undertake their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. i-80 Gold Corp.'s QA/QC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results.

Tyler Hill, CPG-12146, Senior Geologist at i-80 is the Qualified Person for the information contained in this press release and is a Qualified Person within the meaning of National Instrument 43-101.

i-80 Gold Corp. is a well-financed, Nevada-focused, mining company with a goal of achieving mid-tier gold producer status through the development of multiple deposits within the Company's advanced-stage property portfolio with processing at i-80's centralized milling facility that includes an autoclave.
