PPTA Perpetua Resources Corp

BOISE, Idaho, Nov. 14, 2022 /PRNewswire/ - Perpetua Resources Corp. (Nasdaq: PPTA) (TSX: PPTA) ("Perpetua Resources" or "Perpetua" or the "Company") announced today that its unaudited condensed consolidated financial results for the period ended September 30, 2022 were filed. 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, develop one of the largest and highest-grade open pit gold mines in the country and restore an abandoned brownfield site. Perpetua Resources is focused on advancing the permitting for the Stibnite Gold Project ("Project") through the National Environmental Policy Act ("NEPA") process.

• Zero lost time incidents or reportable environmental spills in the third quarter of 2022
• Completed summer field program including stream diversion activities and the removal of the Defense Minerals Exploration Administration legacy waste rock dump from within and along a tributary to the East Fork of the South Fork of the Salmon River
• Continued productive mediation discussions with the Nez Perce Tribe; an extension to the stay on the Clean Water Act matter was recently granted through January 31, 2023
• Awarded Department of Defense funding to study antimony from Stibnite Gold Project
• Announced the United States Forest Service ("USFS") published the Supplemental Draft Environmental Impact Statement ("SDEIS") which identified Perpetua Resources' proposed action as the Preferred Alternative

"Perpetua Resources continued to advance our project through the permitting process, completed initial stream diversion activities contributing to water quality improvements at site, and progressed productive mediation discussions with the Nez Perce Tribe," said Laurel Sayer, President and CEO of Perpetua Resources. "We are excited to have received two funding grants from the Department of Defense to study production of military-grade antimony trisulfide and that our improved project is now available for public review."

On October 28, 2022, the Company announced the USFS released the Supplemental Draft Environmental Impact Statement on the Stibnite Gold Project for public comment and has identified Perpetua's proposed action, the "Modified Mine Plan," as the Preferred Alternative. The USFS also concluded the Preferred Alternative would reasonably accomplish the purpose and need for consideration of approval of the Stibnite Gold Project, while giving consideration to environmental, economic, and technical factors.

Under NEPA, a "Preferred Alternative" is identified by a Federal agency in a Draft Environmental Impact Statement to let the public know which action the agency is leaning toward selecting as final. Selection of the Preferred Alternative by the USFS is a major milestone in the advancement of the Project and provides clarity for the remainder of the NEPA process.

The SDEIS public review period is set at 75 days, expiring on January 10, 2023 unless extended. Following completion of the comment period and analysis, the Company expects the USFS to provide a schedule update including the expected timing to a Final Environmental Impact Statement ("FEIS") and draft Record of Decision and to a final Record of Decision.

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.

Investors should be aware that the publication of the SDEIS and the identification by the USFS of the Modified Mine Plan as the Preferred Alternative does not indicate any commitments on the part of the USFS with regard to a final decision. In developing the Final Environmental Impact Statement ("FEIS"), the next phase of the NEPA planning process, the USFS may select various actions based on the Modified Mine Plan or each of the alternatives analyzed in the SDEIS. The SDEIS is subject to review and comment by the public through the public review period, which may be extended by the USFS in its sole discretion.
