FIRST MINING PROVIDES UPDATE ON PICKLE CROW GOLD PROJECT

First Mining Gold Corp.'s joint venture partner at First Mining's Pickle Crow gold project, FireFly Metals Ltd., has agreed to sell its 70-per-cent interest in PC Gold Inc., the entity that holds the project, to Bellavista Resources Ltd. (Australian Securities Exchange: BVR), for 60 million Bellavista shares valued at $45-million (Australian) based on the concurrent financing price (see below) to be distributed to FireFly shareholders and $37.5-million (Australian) in Bellavista performance rights. In addition, Bellavista is seeking to raise $25-million (Australian) at a price of 75 Australian cents per Bellavista share.

The Bellavista team is led by Glenn Jardine as managing director and Peter Canterbury as finance director. Mr. Jardine and Mr. Canterbury are both experienced executives who led De Grey Mining until its successful $3.3-billion (U.S.) sale to Northern Star Resources Ltd. in May, 2025.

"This is a transformative transaction for the Pickle Crow gold project," stated Dan Wilton, chief executive officer of First Mining. "We would like to thank the FireFly team for all the years of hard work put into the project and are very excited to work with the Bellavista team going forward. The Bellavista team have been one of the most successful groups in Australia advancing late-stage gold projects through the development cycle, having sold De Grey for more than $3-billion (U.S.) in 2025. We look forward to seeing the Pickle Crow gold project, one of the largest high-grade gold resources in any Tier 1 jurisdiction, advanced with the significant funding that Bellavista will raise."

The transaction is expected to close in Q2 2026 and Bellavista has indicated its intention to exercise the PC Gold buydown right to increase their ownership to 80 per cent of the project by paying $3-million in cash to First Mining. Upon the exercise, First Mining's ownership interest in PC Gold will be reduced from 30 per cent to 20 per cent and its interest in PC Gold is free carried to a decision to mine at Pickle Crow.
