Perpetua Resources Corp. (Nasdaq: PPTA) (TSX: PPTA) (“Perpetua Resources” or “Perpetua” or the “Company”) strongly supports the Idaho Congressional Delegation’s united call for domestic critical mineral production including the timely completion of permitting reviews necessary for development of Idaho’s critical mineral resources which will bolster our Nation’s economic independence and security amid geopolitical instability and unprecedented supply chain disruptions.

In floor remarks delivered this week, Senators Mike Crapo and Jim Risch along with Congressmen Mike Simpson and Russ Fulcher resolutely called for action on critical mineral supply chains and pointed to the need to advance proposed projects that would tap into Idaho’s vast antimony and cobalt resources. Perpetua Resources’ Stibnite Gold Project has one of the world’s largest resources of antimony not controlled by China or Russia and could provide the only domestically mined source of a critical mineral deemed essential for clean energy battery storage technology and the Nation’s defense needs. 

“While we need to take strong actions on Russia, the reality is that we source many of our raw minerals from them. As we tighten our grip on their financial system and exports, we must prioritize domestic sourcing and reduce our reliance on countries like Russia and China,” said the Idaho delegation. “The time is now for this Administration to take real action to prioritize a strong domestic supply chain for these essential minerals. We do not want to compromise any of our environmental or other standards. We are simply calling on the Administration to prioritize the timely completion of the permits for currently proposed projects so we may take back control of a fundamental piece of many of our essential industries: critical minerals production.”

“The need for responsible domestic mining to secure our economic, defense, and energy future is not lost on the people of Idaho or the American people,” said Laurel Sayer, President & CEO of Perpetua Resources. “Perpetua is fortunate to have a congressional delegation that recognizes a safe, reliable, and responsible supply chain starts right here at home and supports the growing bipartisan unity to encourage domestic mineral production.  Our vision at Perpetua Resources has always been to restore an abandoned mine site while producing the critical resources our Country needs for a more secure and sustainable future. Now, more than ever, turning this vision into reality is vital for our Nation’s success. As we enter the later stages of permitting, we are confident that the robust review process has created improved project outcomes while also prioritizing community and stakeholder transparency.”

Critical Project for the American Future
The Stibnite Gold Project in central Idaho is designed to restore environmental conditions at a legacy mine site while responsibly developing one of the highest-grade, open pit gold resources in the United States and becoming the only domestically mined source of the critical mineral antimony.

With key applications in energy and defense technology, securing a domestic supply of antimony is more important than ever. Antimony is a key component for grid storage battery technology and Perpetua is uniquely positioned to play a vital role in the decarbonization of the world through its supply agreement with Ambri. Vital to defense materials, antimony was listed by the Department of Defense as a shortfall material in the 100-Day Supply Chain Review Report (June 2021). 

The U.S. Geological Survey recently reported that foreign reliance is growing, with China, Russia and Tajikistan controlling 90% of the world supply of antimony and no domestically mined sources (USGS, 2022 Mineral Commodity Summary).    

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 the lowest carbon emissions grid in the nation and a portion of the antimony produced from the Project will be supplied to Ambri, a US-based company commercializing a low-cost liquid metal battery essential for the low-carbon energy transition.  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.
