High-Grade Gold Identified From Underground Drilling At Granite Creek

RENO, NV - i-80 Gold Corporation reported continued positive assay results from the ongoing underground drill program at the Granite Creek Property, located in Humboldt County, Nevada.

New high-grade results are from drilling from the 4790 Level targeting mineralization in the Range Front, Adam Peak, and Otto fault horizons, the first area being targeted for mining and located proximal to and below existing mine workings. Multiple target areas are being drilled from underground including testing the down-dip potential of the Otto, Adam Peak and Ogee Zones. The deepest hole drilled to test the extension at depth of the main mine horizons in the ongoing program, iGS21-15, intersected high-grade gold mineralization in multiple horizons including 13.3 g/t Au over 13.1m & 20.3 g/t Au over 7.5m & 10.1 g/t over 17.5 m with true width being 33-55% of intercepts.

Highlight results from initial underground drilling from Level 4790 include: 25.4 g/t (grams per tonne) Au (gold) over 3.9 m in hole iGU21-27; 12.6 g/t Au over 3.0 m in hole iGU21-28; 10.8 g/t Au over 1.2 m in hole iGU21-29; 13.4 g/t Au over 1.1 m in hole iGU21-30; 14.7 g/t Au over 1.5 m, 10.2 g/t Au over 3.5 m & 7.5 g/t Au over 6.1 m in hole iGU21-31; and 19.3 g/t Au over 1.1 m, 8.0 g/t Au over 3.0 m & 9.4 g/t Au over 2.9 m in hole iGU21-32.

The current program is expected to comprise more than 30,000 meters (m) from surface and underground with continued assay results to be provided as received. The primary goal of the 2022 drill program is to advance underground opportunities to production with refractory mineralization from the underground operation at Granite Creek initially trucked to Twin Creeks for processing, pursuant to the agreement recently entered into with Nevada Gold Mines, until such time that the Company's Lone Tree facility is operational.

Tyler Hill, Senior Geologist, said, "These results continue to delineate high-grade mineralization in multiple zones being defined in advance of mining at Granite Creek. We have added additional underground infrastructure in order to commence stepping out at depth where we continue to see high-grade intercepts including 7.4 g/t Au across 73.2 meters in iGS21-15 (see press release dated February 8, 2022). We also remain primarily focused on defining the new South Pacific Zone where we are seeing strong alteration and faulting in most holes drilled to-date."
