High-Grade Results From South Pacific Zone At Granite Creek

RENO, NV - i-80 Gold Corporation reported on the final six holes drilled in the successful 2022 surface drill program targeting the high-grade South Pacific Zone at the Granite Creek Property located in Humboldt County, Nevada. The South Pacific Zone ("SPZ") was discovered in 2021 and is host to high-grade gold mineralization located immediately north of the underground mine workings at Granite Creek. The 2021/2022 drilling campaigns were very successful in delineating and expanding mineralization in the SPZ with new results continuing to confirm significant upside potential. Hole iGS22-26 is the deepest and most northerly hole drilled to test this horizon, intersecting an impressive 15.7 g/t gold (Au) over 6.6 meters (m), approximately 170 m north of iGS22-05 (16.4 g/t Au over 15.3 m). The SPZ remains wide open for expansion along strike to the north and at depth.

Highlight new results from 2022 drilling in the South Pacific Zone: 15.7 g/t Au over 6.6 m (0.46 oz/ton Au over 21.8 feet) in hole iGS22-26; 13.9 g/t Au over 4.6 m (0.41 oz/ton Au over 15.0 feet) in hole iGS22-27; 23.2 g/t Au over 5.3 m (0.68 oz/ton Au over 17.5 feet) in hole iGS22-28; 8.5 g/t Au over 5.6 m (0.25 oz/ton Au over 18.3 feet) including 10.9 g/t Au over 2.3 m (0.32 oz/ton Au over 7.5 feet) in hole iGS22-29; and 9.9 g/t Au over 11.9 m (0.29 oz/ton Au over 39.0 feet) including 18.0 g/t Au over 4.8 m (0.53 oz/ton Au over 15.6 feet) in hole iGS22-30.

The SPZ is a priority for development and the Company is currently extending the decline to depth in order to provide access to the SPZ on an expedited basis with a target to complete underground drilling and bring the SPZ into the Granite Creek mine plan in 2023. The Company will now complete an updated resource for the underground mineralization at Granite Creek that will be included in a subsequent economic update that is expected to be released in Q1-2023. Table 1 provides a summary of results from the final six holes drilled in the SPZ in 2022. Additional drilling is being planned for 2023 both along strike and at depth to continue resource expansion.

"Drilling in the South Pacific Zone has ended the year on a high note with the final six holes intersecting high-grade gold mineralization over mineable widths and further extending the deposit along strike to the north.", said Tyler Hill, Senior Geologist. "The continuity of high-grade mineralization makes the SPZ a priority for development and we look forward to continued expansion drilling in the new year."
