i-80 GOLD CORP. announced continued positive results from the ongoing underground drill program at the Company's Granite Creek Mine Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada. The underground zones at Granite Creek will be included in a resource update following the 2022 program that is expected to comprise approximately 30,000 meters of drilling from both surface, focused on the South Pacific Zone, and the underground Ogee, Otto and Adams Peak Zones.

The company is currently mining a bulk sample from the underground zones to deliver an initial 10,000 tons to Nevada Gold Mines' nearby Twin Creeks Mine for a metallurgical test, as per the processing agreement, which will allow for the deposit to be developed and ramped up for continuous mining. 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. 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.
