Perpetua Resources Announces First Quarter 2022 Highlights

BOISE, Idaho, May 16, 2022 /CNW/ - 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 March 31, 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 through the National Environmental Policy Act ("NEPA") process.

• Zero lost time incidents and zero reportable environmental spills in the first quarter of 2022
• Strengthened Board with appointment of Laura Dove who brings three decades of external affairs and stakeholder management experience
• Promoted Jessica Largent to CFO and hired Chris Fogg as Investor Relations Manager
• Launched Sustainability Roadmap outlining 13 goals that will guide Perpetua
• Released the Company's first annual report as a U.S. domestic issuer
• Continued productive mediation discussions with the Nez Perce Tribe and an extension to the stay on the Clean Water Act matter was recently granted through July 31, 2022
• Prepared contractor competitive bid package for the stream diversion clean up work expected to begin this summer under the Administrative Settlement and Order on Consent ("ASAOC")
• Welcomed Idaho's Congressional Delegation submitting floor remarks and issuing a statement supporting critical mineral independence
• Stibnite Advisory Council began review of the first data collected from the Independent Water Quality Monitoring program

"Perpetua Resources had a productive quarter as we continued to advance our project through the permitting process, further strengthened our team and launched our Sustainability Roadmap," said Laurel Sayer, President and CEO of Perpetua Resources. "I look forward to the public seeing how our project improvements are designed to leave water quality and overall habitat in better shape than today while also responsibly producing critical minerals for our national interests. I remain confident that the additional evaluation of our project will address the concerns raised during the last public review and we are hopeful that it will allow the U.S. Forest Service to designate a preferred project alternative in the third quarter of 2022."

On February 22, 2022, Perpetua announced the U.S. Forest Service ("USFS") is expected to publish the Supplemental Draft Environmental Impact Statement ("SDEIS") for public review early in the third quarter of 2022. In the first quarter of 2022, the USFS completed all of the 17 specialist reports for cooperating agency review and recently circulated the preliminary SDEIS for cooperating agency review. The comprehensive scientific analysis by the USFS and cooperating agencies, combined with the additional public review of the SDEIS, fortify the rigorous process mandated by NEPA.

The Company also advanced work on several ancillary permits in the first quarter of 2022, which are being progressed in parallel with the NEPA process. The Air Permit to Construct draft permit was released for public comment by the Idaho Department of Environmental Quality ("IDEQ") in January 2022. The public comment period closed in March 2022 after a 30 day extension. In addition, the Idaho Pollution Discharge Elimination System ("IPDES") application for industrial outfalls was submitted in January and deemed complete in early March. Perpetua's water rights permit application is continuing through the administrative process after being submitted to the Idaho Department of Water Resources ("IDWR") in 2021.

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.
