PERPETUA RESOURCES PUBLISHES 2024 SUSTAINABILITY REPORT

Perpetua Resources Corp. has released its 2024 sustainability report highlighting the company's key achievements and progress in advancing its environmental, social and governance (ESG) goals. The report, which is the company's 12th annual sustainability report, provides disclosure of ESG (environmental, social and governance) topics and aligns with the Sustainability Accounting Standards Board (SASB) reporting framework for the metals and mining industry.

"This year's sustainability report chronicles a period of significant progress for the company, guided by our dedication to responsible stewardship and investment in the region we're proud to call home," said Jon Cherry, president and chief executive officer of Perpetua Resources. "A highlight of this past year was receiving our final environmental impact statement (FEIS) and a draft record of decision (ROD) in September, 2024, followed by receipt of a final ROD in January, 2025. These achievements propel us ever closer to bringing this important project on line, allowing us to secure critical minerals for America's national security and provide much needed environmental reclamation to the historical Stibnite mining district."

2024 sustainability report highlights:

• 154 months (12-plus years) with no reportable spills;
• 109 months with no lost-time incidents;
• 100 per cent of employees participated in business integrity and compliance-related training;

• Team members spent 1,204 hours serving the community;
• Spent $23.6-million in Idaho in 2024; more than $132-million since 2014.

Perpetua Resources' 2024 sustainability report provides an in-depth look at the company's sustainability achievements over the past year as well as the company's efforts to provide the United States 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.
