On February 25, 2026, i-80 Gold Corp. (the “Company”) issued a press release titled “i-80 Gold Extends Deadline for Holders of Convertible Debentures to Submit Interest Conversion Election Notices.” A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information contained in this Item 7.01 and Exhibit 99.1 attached hereto is being furnished and shall not be deemed filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liability of that section, and shall not be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

On February 25, 2026, the Company announced, that in connection with the previously announced mandatory redemption of the Company’s 8% secured convertible debenture notes due 2027 (the “Debentures”), the deadline for the holders of the Debentures (“Debentureholders”) to submit their elections to convert accrued and unpaid interest on the Debentures (the “Interest Election Right”) into common shares of the Company (the “Common Shares”) has been extended to 5:00 pm (EST) on Friday, March 6, 2026 (the “Deadline”).

To exercise their Interest Election Right, registered holders of the Debentures must complete and return a share interest election notice (the “Interest Election Notice”) to i-80 GOLD CORP. c/o TSX Trust Company, 100 Adelaide Street West, Suite 301, Toronto, Ontario M5H 4H1, Attention: Corporation Actions. Email: tmxestaff-corporatetrust@tmx.com by the Deadline. Copies of the Interest Election Notice may be obtained from the Company’s information agent for the redemption, Shorecrest Group.

Debentureholders whose Debentures are registered in the name of an investment dealer, bank, trust company, or other intermediary should immediately contact that intermediary for assistance if they wish to submit an Interest Election Notice in respect of the Debentures they hold in order to take the necessary steps. Intermediaries likely have established cut-off times that are prior to the Deadline. Debentureholders must instruct their brokers or other intermediaries promptly if they wish to submit an Interest Election Notice.

Pursuant to the terms of the indenture for the Debentures dated as of February 22, 2023 between the Company and the TSX Trust Company, as supplemented by the First Supplemental Convertible Debenture Indenture dated as of February 28, 2025 (collectively, the “Indenture”), the conversion price of the Debentures for the purposes of the Interest Election Right will be calculated based on the volume weighted average trading price of the Common Shares on the TSX during the five trading days immediately preceding the date the Debentureholder’s Interest Election Notice is received by the Company c/o TSX Trust Company (in accordance with Section 13.1 of the Indenture), less a discount of 15%, converted into U.S. dollars at the Bank of Canada rate on such date. Debentureholders who do not submit an Interest Election Notice by the Deadline will, pursuant to the terms of the Indenture, be paid in cash for their accrued and unpaid interest on the Debentures.

When submitted, an Interest Election Notice is irrevocable. Debentureholders who have already submitted an Interest Election Notice do not need to take any further action. Interest Election Notices that were previously submitted cannot be withdrawn.

This Current Report on Form 8-K is not a notice of redemption or convertibility of the Debentures. The redemption of the Debentures is being made solely pursuant to the Redemption Notice, dated February 11, 2026, relating to the Debentures.
