i-80 Gold Reports Final Results from Phase 1 Drilling Targeting Open Pit Mineralization at the Granite Creek Mine Project in Nevada

Several holes were drilled into the mineralized structures for metallurgical purposes including iGM21-01, 03, 08 and 09. Drilling in the CX-Pit area intersected higher than anticipated grades and additional drilling will likely be completed. Full results from the open pit drilling are set out in Table 1 below. The open pit program was completed for geotechnical and metallurgical purposes in advance of initiating permitting for an open pit mine with on-site processing. The balance of the ongoing drill program is primarily targeting mineralization to advance underground mining on the Property.

The majority of the ongoing program, expected to consist of more than 20,000 metres of drilling that will extend well into 2022, is focused on defining and expanding mineralization within several high-grade target areas proximal to existing underground mine workings at Granite Creek. This program has yielded numerous successes including the identification of an extensive high-grade structure to the north of the underground mine workings that is the focus of surface expansion drilling.

i-80 has completed initial rehabilitation of the underground mine workings and the Company is also completing a major underground drilling program as part of an aggressive plan to re-commence mining. A test mining program is ramping up and a Preliminary Economic Assessment for Granite Creek was recently released, demonstrating robust economics associated with underground and open pit mining at the Property (See press release dated November 9, 2021).

"We continue to realize substantial success in numerous areas at Granite Creek, including the completion of open pit drilling in advance of permit applications", stated Matt Gili, President and Chief Operating Officer of i-80. "These successes bode well for the planned ramp-up of underground mining, planned for H1-2022 and the long-term future of this exciting property."

Granite Creek is strategically located immediately south of 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 3 below). i-80 recently entered into an interim processing agreement with Nevada Gold Mines that will provide for the processing of material from Granite Creek at the nearby Twin Creeks (Sage) plant.

QAQC Procedures

All samples were submitted to Paragon Geochemical Assay Laboratories (PAL) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through PAL are run through standard prep methods and analysed using FA-Pb30-ICP (Au; 30g fire assay) and 48MA-MS (48 element Suite; 0.5g 4-acid digestion/ICP-MS) methods. PAL 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.
