Perpetua Resources Launches Sustainability Roadmap
BOISE, ID – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua”
or the “Company”) launched its Sustainability Roadmap (“Roadmap”) today which outlines 13 goals to
guide the Company as it advances the Stibnite Gold Project (“Project”) towards development. The
Roadmap provides additional transparency and accountability measures for stakeholders, including
community members and employees to track how Perpetua’s E nvironment, Social, and Governance
(“ESG”) commitments will be integrated as the Project advances . Each goal within the Roadmap is
informed by the United Nations’ Sustainable Development Goals ( “UNSDGs”) to align Perpetua’s path
with global objectives to promote a more sustainable future.
“Our actions over the last decade demonstrate our deep commitment to building a company where
responsible redevelopment of the historical Stibnite Mining District can bring environmental, social and
economic benefits” said Laurel Sayer, President and CEO of Perpetua Resources. “Launching Perpetua’s
Sustainability Roadmap provides an additional level of transparency for all of our stakeholders as we
advance the Stibnite Gold Project.”
Perpetua Resources and t he Stibnite Gold Project are uniquely positioned to demonstrate an industry-
leading sustainability approach. The Project is designed to restore an abandoned mine area through
reprocessing and safely storing millions of tons of legacy mine tailings , restoring river habitat and fish
migration access, and improving wetlands . The Project can also support the clean energy transition as
the only domestically mined source of the critical mineral antimony , which is an essential component in
Ambri’s long-duration storage batteries. Additionally, the Perpetua team has prioritized gender diversity
with over 40% female employees and over 65% female senior leadership, led by CEO Laurel Sayer.
“Sustainability has always been a t the forefront for Perpe tua,” said Sayer. “We began by prioritizing
community partnerships, designing for environmental uplift and recruiting a diverse team that represents
some of the best in the industry . Now, we are advancing our efforts by defining a path for responsible
mineral development here at home.”
The Company’s vision to responsibly restore an abandoned mine site, produce critical minerals required
for U.S. security and clean energy, and bring benefits to surrounding communities formed the foundation
for the Roadmap . The goals were developed in alignment with Perpetua’s ESG policy and broader
sustainability strategy and support multiple UNSDGs.
Perpetua Resources’ Sustainability Roadmap goals are:
1. Improve and protect water quality. Perpetua Resources’ Plan of Restoration and Operation is
designed to improve water quality at Stibnite to be better than it is today.
2. Conserve water. Conserving and reusing water are key to minimizing the impacts of the
Stibnite Gold Project.
Responsible Mining. Critical Resources. Clean Future.

3. Limit our footprint. The Company has already reduced the footprint of its Project by 13%
compared to the original design. Additionally, 51% of the footprint is on previously disturbed
land. It is one of the only projects in North America that plans to reprocess previously mined
material to restore a brownfields site.
4. Be a responsible link in the clean energy supply chain. Perpetua signed an agreement to
supply a portion of the antimony produced at Stibnite to Ambri Inc, for the development of
grid-scale storage batteries that can help decarbonize the U.S. energy grid.
5. Work with communities and regulators to refine environmental outcomes of the Stibnite
Gold Project. Public and agency feedback has been essential in the design of the Project.
Perpetua will use this feedback to identify ways to improve the social and environmental
outcomes of our project.
6. Nurture connections with tribal communities and identify opportunities to
collaborate. Perpetua is committed to continuing to work with tribal leadership, staff and their
membership to ensure the Project honors and protects tribal treaty rights.
7. Foster an open and transparent relationship with local communities. The Stibnite Advisory
Council, which was formed by the 2018 Community Agreement, is a vehicle for the Company
to connect directly with the communities closest to our site throughout the life of the Project.
8. Create economic partnerships that sustain beyond the life of the mine. Perpetua
Resources entered into a profit-sharing agreement to fund the Stibnite Foundation. This
locally-run charitable endowment is designed to have a lasting impact by supporting local
social, environmental and health programs.
9. Develop a diverse and inclusive team. The Company is committed to recruiting, building
and retaining a diverse team.
10. Adopt a long-term Environment, Social and Governance reporting framework. Perpetua
Resources will strive to align its ESG disclosure with the SASB reporting framework beginning
with its 2021 sustainability report to be released later this year.
11. Disclose and report current and future GHG emissions. Perpetua plans to report annual
greenhouse gas (GHG) emissions through a certified third-party to ensure transparency in
emissions reporting.
12. Set science-based GHG target. Once a Project design is approved by regulators, the
Company will establish an anticipated baseline for GHG emissions and intends to develop
targets based on feasible offsets, mitigations and reductions.
13. Protect our people and our communities. Perpetua will continue to implement best practices
and set high safety and training standards to keep our people and our communities safe.
Perpetua Resources has published annual sustainability reports since 2013, detailing the Company’s
actions in communities and for the environment and will launch its ninth report later this year . These
reports can be viewed on Perpetua’s website at https://perpetuaresources.com/sustainability/. Perpetua
Resources expects to set more specific and measurable ESG targets based on the final project design
and anticipated outcomes once all permits for the Stibnite Gold Project have been issued.

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-

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
