Intersection Of High-Grade Gold In Underground Drilling At Granite Creek

RENO, NV - i-80 Gold Corporation reported positive initial assay results from the ongoing underground drill program at the Granite Creek Property located in Humboldt County, Nevada. High-grade results from drilling from the 4740 Level targeting mineralization in the Otto and Adam Peak fault horizons proximal to and below existing mine workings confirm consistency of mineralization in one of the initial areas being defined for underground mining. When combined with historic high–grade drilling in this area, that returned numerous high-grade results including 20.8 g/t Au over 6.1 m in hole PRC-13-084 and 17.8 g/t Au over 6.1 m in hole APRF-225, a continuous zone of mineralization is being defined that remains open at depth.  The Otto fault horizon is one of the multiple target areas being drilled, and several holes intersected gold mineralization in multiple horizons.  The current program is expected to comprise more than 20,000 meters (m) from surface and underground with continued assay results to be provided as received.

The primary goal of the 2021 drill program is to advance underground and open pit opportunities to production.  It is expected that refractory mineralization from the underground operation at Granite Creek will initially be trucked to Twin Creeks for processing, pursuant to the agreement recently entered into with Nevada Gold Mines, until such time that the Lone Tree facility is operational. A Preliminary Economic Assessment for Granite Creek is nearing completion and expected to be released in the near future.

Tyler Hill, Senior Geologist, said, "These results confirm the high-grade opportunity that we are developing at Granite Creek and demonstrate excellent continuity of mineralization within the Otto and Adam Peak fault horizons that appear to broaden with depth.  Step-out drilling is being completed along strike and at depth, and we have intersected strong alteration and faulting in most holes drilled to-date".
