Perpetua Resources Supports Congressional Call to Action on US Critical Mineral
Production
Idaho Congressional Delegation calls for timely permitting for critical mineral projects in response to
Russia’s invasion of Ukraine and America’s overreliance on foreign adversaries.
More than 75% of antimony production controlled by China and Russia.
Stibnite Gold Project is designed to restore an abandoned mine site while responsibly producing gold
and the only domestically mined source of antimony, essential for clean energy and defense materials.
BOISE, ID – 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 develop ment 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 lis ted 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
