i-80 Gold Drilling Returns Best Intercept To-Date in the South Pacific Zone at Granite Creek 16.3 g/t Au over 15.7m and 33.7 g/t over 3.7m in hole iGS21-18

The South Pacific Zone ("SPZ") is a new zone of high-grade gold mineralization located immediately north of the underground mine workings at Granite Creek (see Figure 1). In 2021, sixteen (16) holes were drilled to test the SPZ (including one hole that was abandoned prior to reaching target depth), successfully defining multiple fault structures that are demonstrating continuity of mineralization over a strike length of approximately 600 metres and a dip length of approximately 250 metres that remains wide open for expansion along strike and at depth. Hole iGS21-18 was drilled in the southern portion of the horizon, closer to the underground workings, and as in several previous holes returned impressive gold grades and widths of mineralization in multiple horizons.

Highlight results from hole iGS21-18 in the South Pacific Zone (and adjacent horizons):

• 16.3 g/t Au over 15.7 m (0.48 oz/ton Au over 51.5 feet)
• 33.7 g/t Au over 3.7 m (0.98 oz/ton Au over 12.0 feet)

The SPZ is the priority target of the ongoing surface drill program at Granite Creek and will be included in a resource update following the 2022 program. SPZ consists of multiple subvertical fault structures located within both the Upper and Lower Comus rock units that appear to trend north to northeast (see Figures 1 and 2). Continued step-out drilling to expand mineralization both along strike and at depth is being completed in 2022. Table 1 provides a complete summary of results from drilling in the SPZ in 2021.

"When combined with the Ogee Zone, that is the focus of underground drilling at Granite Creek, we are extremely excited by the results to-date in the South Pacific Zone that confirm the significant upside opportunity", stated Tyler Hill, Senior Geologist of i-80. "Drilling in 2022 will continue to step-out along strike and at depth to further expand the mineralized envelope, while at the same time, we are extending the decline to expedite development and mine planning of the SPZ."

High-grade mineralization at Granite Creek occurs in a near-identical geological setting as that at the multi?million?ounce Turquoise Ridge Mine located immediately to the north (see Figure 3); 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.

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.

QAQC Procedures

All samples were submitted to ALS Minerals (ALS) of Sparks, NV, which is ISO 9001 and 17025 certified and accredited laboratories, independent of the Company. Samples submitted through ALS are run through standard prep methods and analyzed using Au-AA23 (Au; 30g fire assay) and ME-ICP41 (35 element suite; 0.5g Aqua Regia/ICP-AES) for ALS. ALS also undertakes 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.
