Insights

The USFS's authorization of the Stibnite Gold Project marks a significant milestone for Perpetua Resources. With 4.8 million ounces of estimated gold reserves and an expected annual production of 450,000 ounces, this project positions itself as one of the highest-grade open pit gold mines in the U.S. The projected all-in sustaining costs of $450 per gold ounce are notably competitive, potentially leading to strong profit margins.

The dual-commodity nature of the project, producing both gold and antimony, provides a unique advantage. The 148 million pounds of antimony reserves could become strategically crucial given China's impending export restrictions. This positions Perpetua as a key player in the U.S. critical minerals supply chain.

The Stibnite Gold Project presents an intriguing balance between resource extraction and environmental restoration. The plan to restore native fish passage, improve water quality and increase wetland acreage by 63% demonstrates a commitment to environmental stewardship. The project's design to reprocess and safely store legacy tailings, potentially reducing arsenic in rivers by up to 90%, is particularly noteworthy.

However, it's important to monitor the actual implementation and long-term impacts. The 14-year scientific study and rigorous NEPA process provide a solid foundation, but ongoing oversight will be essential to ensure the promised environmental benefits materialize alongside resource extraction.

The Stibnite Gold Project's antimony production capability has significant national security implications. As China dominates global antimony production and is set to restrict exports, securing a domestic supply becomes important for the U.S. Antimony's importance in defense, clean energy and technology applications makes this project strategically vital.

The whole-of-government approach, evidenced by the $75 million Department of Defense award and $1.8 billion EXIM Letter of Interest, underscores the project's national importance. This level of federal support suggests a smoother path for future regulatory and financing hurdles, potentially accelerating the project's timeline and enhancing its economic viability.

U.S. Forest Service to publish Final Environmental Impact Statement and favorable Draft Record of Decision tomorrow.

Stibnite Gold Project is poised to become the next world class gold mine and the only U.S. mined source of the critical mineral antimony.

Decision comes days before China's antimony export restrictions go into effect.

BOISE, Idaho, Sept. 5, 2024 /PRNewswire/ - Perpetua Resources Corp. (Nasdaq: PPTA) (TSX: PPTA) ("Perpetua Resources" or "Perpetua" or the "Company") today announced that the United States Forest Service ("USFS") has completed the Final Environmental Impact Statement ("FEIS") and is issuing a Draft Record of Decision ("DROD") authorizing the Stibnite Gold Project ("Project"). According to a USFS press release, both documents will be published tomorrow, September 6, in the US Federal Register. Based on the USFS schedule published in July 2024, the Final Record of Decision ("ROD") is anticipated by the end of 2024.

The USFS release confirmed that the "Draft Record of Decision outlines the Forest Services' decision to authorize the 2021 Modified Mine Plan". The decision comes after the completion of rigorous interagency permitting review, scientific evaluation, and public input. The Project is designed to provide environmental benefits to an abandoned mine site while producing gold and unlocking the only reserve of antimony within the United States.

"We believe that the Stibnite Gold Project is a win-win-win," said Jon Cherry, President and CEO of Perpetua Resources. "It's a win for Idaho, it's a win for the environment, and it's a win for America's national security. Our independence from Chinese control over antimony is right here in our backyard, and Perpetua Resources is honored to provide a critical part of the solution to the United States' strategic need for antimony, while also delivering an economically robust gold mine that will create new jobs in Idaho. It's time for the Stibnite Gold Project to help secure our future."

Perpetua's Stibnite Gold Project is positioned to be one of the highest-grade open pit gold projects in the United States with 4.8 million ounces of estimated gold reserves. The Project is expected to produce over 450,000 ounces of gold annually over the first four years with all-in sustaining costs under $450 per gold ounce based on the 2020 Feasibility Study.

As a by-product of gold production, the Project has a reserve of 148 million pounds of antimony. Antimony is essential for national defense, clean energy and technology applications, yet no domestically mined supply currently exists. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, has announced that it will restrict antimony exports. The Stibnite Gold Project has one of the largest reserves of antimony not under Chinese influence and the only U.S. domestic reserve.

"The business case is clear," Cherry continued. "Our project has exceptional economics, with an expected payback period of less than 3 years, while providing net environmental benefits and the critical mineral antimony. We have never been closer to unlocking the value of this unparalleled asset."

The Stibnite Gold Project has undergone a rigorous multi-year, science-based review process that balances environmental outcomes, community and national interest and project economics.

Altogether, the Stibnite Gold Project has undergone:

  • 14 years of scientific study, community engagement, and engineering (2010-2024);
  • 8 years in the National Environmental Policy Act ("NEPA") permitting process (2016-2024); and
  • 150 days of formal public comment in which 28,000 letters were received, with approximately 85% expressing support for the Project.

Following the Draft Record of Decision, there will be a required fixed 45-day objection period and another 45-day resolution period prior to the publication of the final Record of Decision, which is expected at the end of the year based on the USFS's published schedule. 

"It is time for the Stibnite Gold Project," said Deb Filler, a resident of Yellow Pine, the closest community to Stibnite. "We want to see Stibnite restored, and the Stibnite Gold Project is going to make our backyard better. Perpetua Resources has been an exceptional community partner, earning our trust and taking the long and high road to make this Project right for Idaho. We are proud of what this Project will do for our nation, and excited for how it will restore our corner of Idaho."

The Stibnite Gold Project is designed to restore a historic mining district abandoned after 100 years of mostly unregulated mining. As part of the proposed mine plan authorized in the draft Record of Decision, Perpetua Resources will:

  • Restore native fish passage, opening miles of pristine spawning habitat that has been inaccessible for 80 years;
  • Improve water quality by reprocessing and safely storing legacy tailings, reducing arsenic in rivers on site up to 90%; and
  • Restore 450 acres of wetlands for a 63% net increase in wetland acres over existing conditions.

There has been a whole-of-government approach to bring antimony production home to the United States. From $75 million in awards from the Department of Defense, to a $1.8 billion Letter of Interest from U.S. EXIM, there is a profound recognition at the highest levels of government that we need domestic antimony production as soon as possible. With a Final EIS and DROD to be published tomorrow and a Final ROD expected this year, Perpetua has engaged RBC Capital Markets and Endeavour Financial to assist with the evaluation of potential strategic and financing opportunities and to support the Company's application process in connection with the U.S. EXIM $1.8 billion Letter of Interest received in April 2024.
