NEWS RELEASE

U.S. Forest Service Chooses Perpetua Resources’Proposed Stibnite Gold Project as Preferred Alternative

Supplemental Draft Environmental Impact Statementpublished for 75-day public review and comment.

Perpetua’s Proposed Action includes improvementsthat are responsive to public input and designed to improve environmental outcomes.

Perpetua Resources is positioned to providethe only U.S. mined source of antimony, ending reliance on China and Russia for the critical mineral essential to national defense andclean energy transition.

BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or “the Company”) announced today that the United States Forest Service (“USFS”) has released the Supplemental Draft Environmental Impact Statement (“SDEIS”) on the Stibnite Gold Project (“Project”) for public comment and has identified Perpetua’s proposed action, the “Modified Mine Plan,” as the Preferred Alternative. Identification 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 National Environmental Policy Act (“NEPA”) process.

“The Stibnite Gold Project is one step closer to restoring an abandoned mine site, providing hundreds of family-wage jobs for Idahoans, producing the only domestic mined source of antimony to protect our national security, and supporting America’s clean energy transition,” said Laurel Sayer, President and CEO of Perpetua Resources. “Perpetua submitted an initial plan of restoration and operations six years ago and our team has worked tirelessly to develop a responsible, modern mining project that can have a positive impact on Idaho and our nation. We have listened to community feedback and the process has made our plan even better.”

Thorough Permitting Process Improved Project:

In response to public and agency feedback on the Draft Environmental Impact Statement (“DEIS”) released by the USFS in August 2020, Perpetua proposed modifications to the mine plan analyzed in Alternative 2 in the DEIS and submitted a Modified Mine Plan to the USFS in December 2020. The Modified Mine Plan included refinements to reduce the project footprint, improve water quality, and lower water temperature. The USFS chose to advance this modified project design to an SDEIS to further evaluate the project refinements and compare the Company’s proposed site access via Burntlog Route to an alternative option using current roads. Perpetua’s design improvements in the Modified Mine Plan included:

· Decreased on-site disturbance footprint, a 13%<br>reduction from 2016 design
· Reduced mined material by 10% (44 million tons)
--- ---
· Eliminated waste rock storage areas (168 acres)
--- ---
· Reduced volume of Hangar Flats pit by 70% and<br>completely backfilled pit
--- ---
· Added extra geosynthetic covers to protect long-term<br>water quality
--- ---
· Increased riparian vegetation and low flow channels<br>to reduce water temperature
--- ---
· Developed additional habitat feature to replace<br>bull trout habitat
--- ---
· Modified ore processing circuit to improve tailings<br>chemistry
--- ---

Stibnite Gold Project Designed with Solutionsin Mind:

The Stibnite Gold Project is designed to restore the legacy environmental conditions at the abandoned mine site while responsibly redeveloping one of the highest-grade, open pit gold resources in the United States and become the only domestically mined source of the critical mineral antimony, which is essential to the national defense and energy sectors.

The Project plans to address the long-standing environmental issues plaguing the historic mine site. Unconstrained tailings and mine waste left behind from over a century of mining activity have increased metal levels in the ground and surface water at Stibnite and salmon have been blocked from native spawning grounds for more than 80 years. Perpetua’s efforts to combine mineral redevelopment with legacy restoration are expected to improve water quality over existing conditions, leave the river with enhanced habitat, open miles of perennial habitat for salmon, and increase the number of wetland acres on site today.

The Project is expected to produce gold and the critical mineral antimony. The United States Government has made clear that securing a domestic antimony supply is strategically important to our national interests. Today, China, Russia, and Tajikistan control 90% of the global supply of antimony and the United States has no mined source. The Stibnite Gold Project has the only identified reserve of antimony in the United States (USGS, 2021) and could provide a responsible and secure domestic source to satisfy the growing demand from the defense and energy sectors.

Supplemental Draft Environmental Impact StatementMaterials:

Individuals who wish to view the SDEIS have 75 days to submit their comments to the USFS. The document can be found in the Environmental Protection Agency EIS database filed under EIS number 20220154 and will be available on the USFS project page at https://www.fs.usda.gov/project/?project=50516. Additional information on the Project and Perpetua’s plans to redevelop and restore the site, reconnect salmon to their native spawning grounds, produce America’s only source of the critical mineral antimony and contribute to the economic success of Idaho can be found at www.PerpetuaResources.com. Comments on the SDEIS are due by January 10, 2023.

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 be found here.
