i-80 Gold Corp. announce additional high-grade results from the ongoing drill program to define mineralization in the upper part of the South Pacific Zone at the Company's Granite Creek Property ("Granite Creek" or "the Property") located in Humboldt County, Nevada. The new results are from seven new holes drilled in the underground campaign focused on the delineation of mineralization within the South Pacific Zone ("SPZ").

The SPZ is located immediately north of the current mine workings and is expected to become the primary zone for mining. Initial stopes in the SPZ are being planned for H1-2024 once mine workings are extended to provide access. The underground drill program is focused on the southern and upper part of the deposit, where initial mining is planned.

Results from the underground program continue to demonstrate continuity of high-grade mineralization with some of the best results received to-date in the South Pacific Zone. Highlight results from the most recent seven new underground drill holes testing the South Pacific Zone at Granite Creek include: GCPU23-33: 17.7 g/t Au over 7.0 m; GCPU23-45A: 27.2 g/t Au over 4.0 m; GCPU24-01: 18.1 g/t Au over 14.4 m; GCPU24-02: 22.0 g/t Au over 29.0 m; GCPU24-04: 11.0 g/t Au over 22.4 m; GCPU24-04: 60.5 g/t Au over 4.1 m. With its improved financial position, the Company is in the process of ramping up a large-scale surface drill program to complete further definition and expansion drilling of the SPZ in advance of an updated resource estimate and Feasibility Study for the Granite Creek Property. Four (4) drill rigs will be used to complete this program.

Additionally, the main decline is being extended to provide access to the SPZ and initial stoping of this new zone is expected mid-year.
