Perpetua Resources Advances Construction of the Stibnite Gold Project
Construction ramps up as Idaho Federal Court rejects efforts to stop critical path activities
Company commences Burntlog Route construction
Critical-path activities target on-time delivery of antimony for U.S. defense interests
BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or the “Company”) announced today that the Stibnite Gold Project (“Project”) continues to advance previously planned critical path construction and infrastructure activities following the May 29 decision by the United States District Court of Idaho denying the Project opponents’ motion for a preliminary injunction related to a lawsuit filed in 2025 by special interest groups. In the decision, the Court found that the Plaintiffs failed to show that the planned activities would cause the Plaintiffs irreparable harm.
On Saturday, May 30, Perpetua commenced additional critical path construction activities for the 2026 field season, including initial work associated with the Burntlog Route, a key infrastructure project designed to support safe and efficient access to the Project site while minimizing impacts to nearby communities and sensitive environmental areas. These road upgrades will continue in parallel with additional planned construction of on-site worker housing facilities, selected powerline upgrades, and approved exploration and geotechnical drilling. This new activity builds upon the early works construction Perpetua began in October 2025 and is focused on maintaining construction schedule for 2029 operations and delivery of urgently needed antimony to the United States military.
Perpetua crews begin construction of Burntlog Route, May 30, 2026
“We are focused on responsibly advancing the Project and executing on the important work ahead of us,” said Jon Cherry, President and CEO of Perpetua Resources. “This construction season is narrow and important to advance major infrastructure for the on-time delivery of antimony to support demand from the U.S. military. We also are pleased to continue with important environmental restoration and our commitment to economic development in Idaho.”
The Stibnite Gold Project is designed to redevelop and rehabilitate the abandoned Stibnite mining district, which was largely mined for antimony and tungsten during World War II and the Korean War. The approved project includes extensive environmental restoration measures intended to improve water quality, remove legacy mine waste, reconnect fish habitat, and restore streams and wetlands within the Project area.
Following years of evaluation of alternatives and study of potential environmental impacts, the U.S. Forest Service identified the Burntlog Route as the preferred access road after determining it provides safer travel, limits proximity to sensitive water ways, and reduces impacts on the environment and residents and recreationalists. Perpetua has also placed financial assurances approved by federal and state agencies to ensure reclamation of construction-related impacts.
The U.S. Department of War has identified the Stibnite Gold Project as the only U.S. mine that would be capable of producing antimony volumes sufficient to meet defense demand by 2029. Antimony from the Stibnite Gold Project also provides a domestic source to support growing commercial demand for antimony. Perpetua’s planned construction activities for this construction season target critical items that must be completed in order to keep development on track to commence gold and antimony production in 2029.
In preparation for the summer construction season, Perpetua Resources has engaged local contractors and service providers to support initial construction activities. These contracts represent approximately $45 million in direct work expected for businesses and communities across Idaho.

Export Import Bank of the United States Approves $2.9 Billion Loan for Development of Perpetua Resources’ Stibnite Gold Project
Landmark loan under EXIM’s Make More in America Initiative supports domestic critical mineral supply chain and hundreds of jobs in rural Idaho
Stibnite Gold Project is poised to develop the only domestic reserve of critical mineral antimony
$2.9 billion loan, combined with Perpetua’s cash on hand, is expected to fully fund estimated capital costs for the construction of the Stibnite Gold Project
BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or the “Company”) announced today that the Board of the Export-Import Bank of the United States (“EXIM”) has unanimously approved a $2.9 billion senior secured long-term loan (“Loan”) under the Make More in America Initiative (“MMIA”) to support the development of Perpetua’s Stibnite Gold Project (“Stibnite” or “Project”). EXIM’s approval comes after extensive technical, financial, environmental and social due diligence and a 25-day notice period to Congress.
"It is time to make more in America and today marks not only a key milestone for Perpetua Resources, but a significant step in mineral security for our country,” said Jon Cherry, President and CEO of Perpetua Resources. “When the federal government and private industry work together on a shared national priority, big things are made possible. The $2.9 billion loan positions us to bring the Stibnite Gold Project to life and signals a new day in American mineral independence and responsible mining. We are immensely proud of our role in strengthening America's national security, creating hundreds of jobs in rural Idaho, and reducing our dependence on foreign adversaries for a mineral we cannot do without.”
The Stibnite Gold Project is an ideal candidate for U.S. EXIM financing as it sits at the nexus of EXIM’s highest priority mandates – strengthening America’s industrial manufacturing supply chains, domestic job support, and critical mineral independence to advance both national security and domestic industrial and commercial manufacturing needs.
EXIM’s decision marks a landmark transaction under the MMIA Initiative and advances American production and manufacturing to be more competitive on the world stage. As the only identified domestic reserve of antimony, EXIM’s investment in the Project advances American critical mineral independence for antimony.
“Idaho’s abundant critical and rare earth minerals are essential to reducing U.S. dependence on foreign suppliers,” said U.S. Senator for Idaho James Risch. “This investment will help expand our domestic critical mineral supply, create high-quality jobs in rural America, and strengthen our national security.”
“This investment strengthens America’s economic and national security by advancing a reliable domestic supply of critical minerals essential to our manufacturing and defense industries,” said U.S. Senator for Idaho Mike Crapo. “The Export-Import Bank’s Make More in America initiative is helping secure the infrastructure needed to reduce our dependence on foreign adversaries, support American workers and reinforce our long-term industrial competitiveness. It is encouraging to see this effort moving forward in Idaho, where it has the potential to create hundreds of high-quality jobs, long-term economic competitiveness and supply chain security.”
The EXIM financing package, combined with Perpetua’s cash on hand, is expected to fully fund the direct construction of the Stibnite Gold Project based on the current capital cost estimates as reported in the Company’s Technical Report Summary as of December 31, 2025. Underpinned by robust economics from gold, the Stibnite Gold Project is designed to responsibly redevelop and restore the abandoned Stibnite Mining District in Idaho to produce gold and the nation’s only reported reserve of the critical mineral antimony. In doing so, the Project would provide investments in environmental cleanup of the historical site, secure a source of antimony for American commercial and defense manufacturing, and create an average of over 700 direct jobs a year over the life of the mine and significant tax revenue for local communities and the state of Idaho.
“There is no better place to deploy US EXIM’s $2.9 billion investment than right here in the heart of Idaho,” said Idaho Governor Brad Little. “The Stibnite Gold Project is exactly the kind of project America needs. It will create hundreds of family-wage jobs and break America’s dependence on our adversaries for the antimony our military and manufacturers need. Thank you to EXIM for this vote of confidence in the Gem State, and congratulations to Perpetua Resources on a milestone that strengthens Idaho and the nation.”
To date, the Stibnite Gold Project has gone through rigorous scientific and public review, was identified as a Transparency Project under the FAST-41 Program and has received substantial support and partnership from the Department of War. Today’s EXIM financing announcement illustrates a whole-of-government approach to advance this project towards production.
The Loan will be available upon completion of definitive documentation and satisfaction of customary conditions precedent, which is expected to occur in the second half of 2026. The Loan is to be structured as a 13-year senior secured credit facility of $2.9 billion, consisting of an upfront facility of $2.4 billion with the remainder to cover capitalized interest during construction and EXIM’s exposure fee. The increase in the principal amount of the Loan compared to the initial EXIM Board review primarily relates to adding an option to move certain planned equipment financing from a third-party financing company into the EXIM Loan.
Interest on the Loan is to be set at the applicable long-dated U.S. Treasury bond rate plus 100 basis points and will be fixed at the time of the first drawdown. Scheduled repayments are anticipated to commence in 2030.
The MMIA Initiative is a Congressionally authorized financing program through EXIM designed to help companies make more in America – especially in sectors critical to national security. The goal of the program is to help American producers obtain financing, compete on a global scale and, in the process, generate economic opportunities for hardworking Americans.
EXIM is an independent Executive Branch agency and the official export credit agency of the United States. EXIM’s mission is to support American jobs by facilitating the export of U.S. goods and services. In 2024, Perpetua Resources submitted a Letter of Interest application to EXIM. After EXIM expressed interest in potential debt financing, Perpetua worked on its application for more than a year, officially submitting it in May 2025. In September 2025, the Company received a preliminary project letter and indicative term sheet from EXIM for financing. Since that time, EXIM has conducted extensive due diligence and legal review, including its own environmental and social evaluation of the Project. The final approval from EXIM’s Board of Directors comes two years after the initial interest application was submitted and a year after Perpetua submitted its formal application.
Advisors
The Company’s transaction advisors for the Loan include Endeavour Financial acting as financial advisor, and Hunton Andrews Kurth LLP serving as legal counsel.

Further, release of funding under the loan would be subject to the satisfaction of certain conditions and covenants by the Company.
Investors should be aware that the Project’s designation as a Transparency Project does not imply endorsement of or support for the Project by the federal government, or create a presumption that the Project will receive federal funding. The designation of a project as a Transparency Project may be reconsidered based on updated information.

Perpetua Resources Announces First Quarter 2026 Financial Results
BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or the “Company”) announced today the filing of its unaudited condensed consolidated financial results for the period ended March 31, 2026. For details, please see the Company’s filings available on EDGAR and SEDAR+.
Perpetua Resources’ vision is to provide the U.S. with a domestic source of the critical mineral antimony while developing one of the largest and highest-grade open pit gold mines in the Americas and restoring an abandoned brownfield site. The Company is currently advancing a comprehensive project financing plan along with detailed engineering, long-lead time procurement, early works construction activities and execution planning in anticipation of a final investment and construction decision in the second half of 2026.
“After breaking ground late last year at our Stibnite project, we maintained our momentum in Q1 2026,” said Jon Cherry, President and CEO of Perpetua Resources. “The first quarter saw considerable progress towards securing our comprehensive project financing plans with U.S EXIM and a final vote is expected in the coming weeks. Meanwhile, we significantly advanced detailed engineering, continued early works construction and began procurement for long-lead time items ahead of our Final Investment Decision expected in the second half of 2026.”
First Quarter 2026 and Recent Highlights
The U.S. Export-Import Bank ("U.S. EXIM") Board posted the Congressional notice for an approximately $2.7 billion proposed senior secured loan for the Project. The notification period has since expired, and U.S. EXIM's board has advanced the loan to a final vote anticipated in the second quarter of 2026.
The Company's loan has been placed on the agenda for the U.S. EXIM Board meeting on May 21, 2026, reflecting meaningful progress toward financing approval. The agenda is subject to change by the board of U.S. EXIM at any time, and there can be no assurance that the board will vote to approve the loan at the May 21 meeting, at a different meeting, or at all.
If approved, the loan is expected to consist of approximately $2.2 billion for construction of the Project, financial assurance, and certain discretionary corporate and exploration costs, with the remainder comprising capitalized interest and fees.
If approved by the U.S. EXIM Board in the amount indicated, the Company would have sufficient capital to fully finance the Project's estimated direct capital costs of $2,576 million — combining the U.S. EXIM loan with $669.5 million of cash on hand as of March 31, 2026 — as well as financial assurance and discretionary corporate and exploration costs, consistent with the capital expenditure estimate set forth in the December 31, 2025 Technical Report Summary ("TRS").
The Company maintained an exemplary safety and environmental record during the quarter, with zero lost time incidents and zero reportable environmental spills.
In March 2026, the Company published an updated TRS incorporating revised capital and operating expense estimates that reflect continued advancement in engineering, contracting, and Project development through December 2025. The TRS continued to demonstrate compelling project economics for the Stibnite Gold Project across a wide range of gold and antimony price assumptions.
In January 2026, the Company received the final remaining Stream Alteration Permit from the Idaho Department of Water Resources ("IDWR"), finalizing necessary state approvals for work in various streams and other water resources.
Also in January 2026, the Company received the final Idaho Pollutant Discharge Elimination System ("IPDES") permit for industrial wastewater discharges. This permit is currently subject to an automatic stay under Idaho law until an administrative appeal process is completed.
In April 2026, the Idaho Department of Environmental Quality (“IDEQ”) issued a final modified Clean Water Act Section 401 Water Quality Certification for the Project, advancing a key state water quality approval through a further stage of regulatory review. A contested case proceeding challenging certain aspects of the Certification remains pending, and a new hearing date has not yet been scheduled. The Certification remains valid during the pendency of the contested case proceeding.
The Company anticipates receipt of the second phase cyanidation permit from IDEQ in the second quarter of 2026, advancing regulatory approval of the Project's cyanidation facility. IDEQ released a draft of the second phase permit for public comment in February 2026.
Perpetua is aware that the environmental plaintiffs in the 2025 NEPA challenge in the U.S. District Court in Idaho on May 8, 2026, filed a motion for a preliminary injunction seeking to delay certain construction activities on federal land planned for the Stibnite Gold Project. The motion excludes the early works activities that Perpetua has been advancing under a prior stipulation agreed to by the Company and the plaintiffs, and those activities will continue. The hearing on the motion is set for May 28th, and a ruling is expected shortly thereafter.
The Company successfully transitioned its Engineering, Procurement, and Construction Management ("EPCM") responsibilities for the Project's processing plant and related scopes of work from Ausenco to Hatch, ensuring continuity and strengthening execution capacity as the Project advances toward construction.
