Perpetua Resources Applauds Idaho’s SPEED Act to Streamline Permitting and Support

Critical Projects

BOISE, ID – Perpetua Resources Corp. (Nasdax: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or

the “Company”) today praised Idaho Governor Brad Little’s Executive Order 2025 -02, the Strategic

Permitting, Efficiency, and Economic Development (“SPEED”) Act. This landmark measure establishes a

SPEED Council to improve coordination among state agencies, reduce permitting delays, and drive forward

projects that promote energy independence, national security, and economic growth.

The SPEED Act is a testament to Idaho's leadership in responsible resource development and recognition

that streamlined permitting can go hand-in-hand with rigorous environmental standards.

The SPEED Act is a crucial step toward advancing critical projects like the Stibnite Gold Project (“Project”).

Once in operation, the Project is expected to provide an average of 550 jobs to rural Idaho and a reliable

domestic source of the critical minera l antimony, which is vital for defense, technology, and energy

applications. With an estimated reserve of 148 million pounds of antimony, the Project could meet up to

35% of U.S. antimony demand in its initial six years of production, significantly reducing reliance on foreign

supply chains. In late 2024, China — which is responsible for nearly half of all mined antimony output

worldwide — cut off antimony exports to the U.S. The Stibnite Gold Project stands to greatly bolster the

United States’ efforts to reduce its reliance on foreign antimony producers and suppliers and strengthen its

strategic mineral security.

"We are thrilled to see Governor Little take decisive action to streamline permitting without compromising

environmental integrity,” said Jon Cherry, President and CEO of Perpetua Resources. “The SPEED Act aligns

perfectly with Perpetua’s vision to restore an abandoned mine site and responsibly develop domestic

mineral resources for a more secure future."

"The SPEED Act exemplifies Idaho’s common sense, forward -thinking leadership,” said Ben Davenport,

Executive Director of the Idaho Mining Association. “We hope that by improving communication and

coordination, Idaho can help vital projects like the Stibnite Gold Project deliver hundreds of well-paid and

highly-skilled jobs to our rural communities."

"Idaho’s SPEED Act is a model for the nation,” said Mark Compton, Executive Director of the American

Exploration & Mining Association. “With enhanced coordination and reduced inefficiencies, Idaho projects

like the Stibnite Gold Project can better deliver the critical minerals our nation needs while safeguarding

the environment.”

The SPEED Act reflects Idaho’s commitment to balancing economic growth with environmental

responsibility. With Idaho’s vast mineral resources, the state can continue its leadership in supporting

projects that bolster national security and energy independence.

About Perpetua Resources and the Stibnite Gold Project

Perpetua Resources Corp., through its wholly owned subsidiaries, is focused on the exploration, site

restoration and redevelopment of gold-antimony-silver deposits in the Stibnite-Yellow Pine district of central

Idaho that are encompassed by the Stibnite Gold Project. The Project is one of the highest-grade, open pit

gold deposits in the United States and is designed to apply a modern, responsible mining approach to

restore an abandoned mine site and produce both gold and the only mined source of antimony in the United

States. Further advancing Perpetua Resources’ ESG and sustainable mining goals, the Project will be

powered by one of the lowest carbon emissions grids in the nation and a portion of the antimony produced

from the Project will be supplied to Ambri, a U.S. -based company commercializing a low-cost liquid metal

battery essential for the low-carbon energy transition. Perpetua Resources has been awarded a Technology

Investment Agreement (“TIA”) of $59.2 million in Defense Production Act Title III (“DPA”) funding to advance

construction readiness and permitting of the Project. Antimony trisulfide from Stibnite is the only known

domestic source of antimony that can meet U.S. defense needs for many small arms, munitions, and missile

types. In addition to the company’s commitments to transparency, accountability, environmental

stewardship, safety and community engagement, Perpetua Resources adopted formal ESG commitments

which can be found here.
