i-80 Gold Finalizes Third-Party Processing Agreements

RENO, Nevada, March 19, 2025 /PRNewswire/ - i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) ("i-80 Gold", or the "Company") is pleased to announce it has finalized two third-party processing agreements (the "Agreements") in respect of toll milling as well as ore sales for refractory and oxide material, respectively. The Agreements remain in effect through to December 31, 2027. The Company is targeting to have the anticipated refurbishment of its Lone Tree autoclave facility complete by December 31, 2027 to allow for all material from the Company's underground gold mines to be processed at its autoclave facility.

The economic terms of the Agreements are reflected in the recently released life of mine cash flows presented in the press releases for the Archimedes Underground Project on February 18, 2025 and the Granite Creek Underground Project on March 5, 2025.

"We are pleased to finalize these Agreements as they are key in enabling i-80 Gold to advance development of two of our three underground gold mines over the next several years, while continuing the planned refurbishment and recommissioning of our Lone Tree autoclave facility. Once commissioned, our autoclave is expected to serve as the central processing hub for material from our underground gold mines," stated Matt Gili, President and Chief Operating Officer.

A class III engineering study on the autoclave refurbishment is expected to be completed by the end of the third quarter of 2025.
