i-80 Gold Closes Previously Announced US$11 Million Private Placement

RENO, NEVADA, May 26, 2025 – i-80 GOLD CORP. (TSX:IAU) (NYSE:IAUX) (“i-80” or the “Company”) is pleased to announce that it has closed the previously announced concurrent private placement (the “Concurrent Private Placement”) of 22,240,000 units (the “Units”) at a price of US$0.50 per Unit for gross proceeds of US$11,120,000.

Consistent with the terms of the Company’s bought deal public offering (the “Offering”) which closed on May 16, 2025, each Unit is comprised of one common share (a “Common Share”) and one-half of one Common Share purchase warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to purchase one Common Share at a price of US$0.70 until November 16, 2027. Units were sold to certain directors, officers, and other current individual shareholders of the Company and will be subject to a hold period of six months under applicable U.S. securities laws, as amended, and a hold period of four months plus one day under applicable Canadian securities laws, from the closing date of the Concurrent Private Placement.

The Offering and the Concurrent Private Placement generated aggregate gross proceeds of US$184,000,000 which are intended to be used on growth expenditures in support of i-80’s new development plan in Nevada and for general working capital and corporate purposes, as more particularly described in the respective U.S. and Canadian prospectus supplements in connection with the Offering.

Certain directors and officers of the Company named below (collectively, the “Insiders”) purchased an aggregate of 1,825,000 Units pursuant to the Concurrent Private Placement (the “Insider Participation”). Each subscription by an Insider in the Concurrent Private Placement is considered a “related party transaction” pursuant to Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”). The Company was exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the Insider Participation pursuant to sections 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, as neither the fair market value of any securities issued to, nor the consideration paid by, the Insiders exceeded 25% of i-80’s market capitalization. The Company did not file a material change report relating to the Insider Participation more than 21 days before the expected closing date of the Concurrent Private Placement as the details of the Insider Participation was not settled at such time.

The securities issued under the Concurrent Private Placement have not been registered under the U.S. Securities Act, or any state or other applicable jurisdiction’s securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act and applicable state or other jurisdictions’ securities laws.

The participation of directors and officers in the Concurrent Private Placement reflects continued confidence in the Company’s strategic direction and growth potential.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
