High-Grade Results From Underground Drilling At Granite Creek

RENO, NV - i-80 Gold Corp. reported on the ongoing 2023 underground drill program that is targeting mineralization in the upper part of the South Pacific Zone at the Company's Granite Creek Property located in Humboldt County, Nevada. The 2023 surface and underground drilling campaign is focused on the delineation and expansion of mineralization within the South Pacific Zone ("SPZ"), and the conversion of some of the deposit to Measured and Indicated resource classification. The SPZ is located immediately north of the Ogee Zone and the current mine workings, and is expected to become the primary zone for mining once developed in 2024.  Mining of initial stopes is being planned for H1-2024 once mine workings are extended to provide access.

The underground drill program is focused on the upper part of the deposit, where initial mining is planned, while surface drilling is currently targeting the northern extension where drilling is also defining high-grade mineralization with recent results that include intervals of up to 15.5 g/t Au over 19.7 m in iGS23-05. Prior to hole GCPU23-19, underground drilling was completed in the current areas being mined in the Ogee Zone and subsequent drilling is focused on the SPZ. The initial results include some of the best results received to-date in the South Pacific Zone.

“Both surface and underground drilling in the South Pacific Zone confirm impressive high-grade gold mineralization, including over substantial widths.", stated Tyler Hill, Senior Geologist. "It is expected to become the primary source of mineralization at Granite Creek beginning in mid-2024 and is comprised primarily of refractory mineralization that will be processed initially at Nevada Gold Mines' Twin Creeks complex pursuant to our processing agreement. The South Pacific Zone remains open along strike to the north and at depth, providing considerable upside."
