Agnico Eagle to invest $180 million in equity and companies to create a joint technical and exploration advisory committee

 JPMorganChase’s $1.5 trillion Security and Resiliency Initiative to invest $75 million in equity

Perpetua Resources Corp. (Nasdaq: PPTA) (TSX: PPTA) announced that the Company has entered into agreements to raise $255 million in equity investments from Agnico Eagle Mines Limited and JPMorganChase. The Private Placement comes days after Perpetua Resources broke ground on the Stibnite Gold Project. Located in central Idaho, the Project is expected to produce the only domestic reserve of the critical mineral antimony, become one of the highest-grade gold producers in the United States, and provide environmental restoration to an abandoned mine site. The Company believes the Private Placement is a better financing alternative for shareholders than pursuing a gold royalty or stream. Agnico Eagle has agreed to invest $180 million in common shares and receive warrants to purchase up to 2,861,229 common shares priced at 35%, 50% and 65% premiums over one, two, and three year periods, respectively. JPMorganChase has agreed to invest $75 million in common shares and receive warrants to purchase up to 1,192,179 common shares priced at 35%, 50%, and 65% premiums over one, two, and three year periods, respectively. The Private Placement was priced at $23.30 per common share, being the closing price of the Company’s common stock on Nasdaq on Friday, October 24, 2025.

“The investments from Agnico Eagle and JPMorganChase are a vote of confidence in the Stibnite Gold Project and America’s critical mineral strategy,” said Jon Cherry, President and CEO of Perpetua Resources. “Investments from two leading, world-class institutions strengthens our capital position, reduces financing risk, and accelerates the development of one of the nation’s most strategic resource projects.”

The Company plans to use the proceeds of the Private Placement, together with cash on hand and anticipated funding from the previously announced application for up to US$2 billion in project financing submitted to the Export-Import Bank of the United States (“EXIM”) in May 2025, for development of the Project, exploration activities, working capital costs, and general corporate purposes.

Agnico Eagle Investment:

Agnico Eagle, the world’s second largest gold producer, has agreed to purchase 7,725,321 common shares for an aggregate purchase price of $180 million, resulting in a 6.5% equity stake in the Company on a non-diluted basis.

“The Stibnite Gold Project is an excellent opportunity in a premier mining jurisdiction. Our investment in Perpetua aligns with Agnico Eagle’s commitment to disciplined and strategic investments through emerging and high-quality opportunities and provides measured exposure to one of the highest-grade open-pit gold deposits in the United States, with significant exploration upside,” said Ammar Al-Joundi, President and Chief Executive Officer of Agnico Eagle.

Agnico Eagle is an industry leader in responsible mineral development. As part of the investment, Agnico Eagle and Perpetua expect to form a joint technical and exploration advisory committee, which will benefit from Agnico Eagle’s world class project expertise, performance, and values to help advance the Project.

Agnico Eagle will also receive warrants to purchase up to 2,861,229 common shares, exercisable at prices of $31.46, $34.95 and $38.45 for the one, two and three year periods following closing, respectively, for potential proceeds of up to $100 million if all warrants are exercised. After giving effect to the issuance of a total of 10,944,205 common shares to Agnico Eagle and JPMorganChase, and assuming exercise of Agnico Eagle’s warrants in full, Agnico Eagle would own 8.6% of the outstanding shares in Perpetua. Pursuant to an Investor Rights Agreement to be entered into between the Company and Agnico Eagle in connection with the Private Placement, among other things, so long as Agnico Eagle retains at least a 1.5% stake in the Company, Agnico Eagle will have the right to participate in future equity offerings to retain its pro rata equity ownership or reach beneficial ownership of up to 9.99% of the Company’s common shares.
