Perpetua Resources Corp. has made key additions to the company's leadership team, bringing on accomplished industry leaders as the company continues early works construction of the Stibnite gold project ahead of a final investment decision expected in the spring of 2026. Perpetua is excited to welcome Jim Norine as senior vice-president, projects, Tim Kahl as senior vice-president, technical services, Dustin Rissmiller as vice-president, human resources, and Joe Fazzini as vice-president, investor relations. Collectively, the newest team members bring several decades of expertise and diverse experiences that will help Perpetua bring its gold and antimony project in central Idaho to life.

"Our team at Perpetua Resources has always been central to our success," said Jon Cherry, president and chief executive officer of Perpetua Resources. "As we enter our next chapter, we are focused on having the right leaders around the table to help us bring the Stibnite gold project on line, secure American antimony, restore the site and bring new economic opportunities to rural Idaho. We are honoured to welcome some of the brightest minds in the industry to Perpetua Resources. They are committed to our vision and ensuring we deliver on our promises."

Mr. Norine joins the company as senior vice-president, projects, with over 25 years of experience in project construction and engineering, delivering large-scale projects throughout the United States and internationally. Of significant advantage to Perpetua, Mr. Norine brings a record of success in delivering multiple mining and processing projects. Before joining Perpetua, Mr. Norine served as regional director, metals, Western (United States), at Hatch Engineering Ltd., a global multidisciplinary management, engineering and development consultancy firm. Most recently in his time at Hatch, Mr. Norine served in the role of the project director for delivery of the engineering and procurement of the Hermosa project in Arizona under an integrated delivery method. Previously in his career, Mr. Norine held positions at Ausenco Engineering USA, as vice-president, southwest U.S., Sundt Construction as senior project manager and at M3 Engineering as project manager. He holds a professional engineering licence (PE) in the state of Idaho.

Mr. Kahl joins the company as senior vice-president, technical services, with over 30 years of experience in design, construction, commissioning, and operating complex mining and process operations. Throughout his career in North and South America, Mr. Kahl has stewarded projects through construction, commissioning, and into operations and brings invaluable operational readiness experience with both precious and base metals operations. Mr. Kahl has served as a consultant to Perpetua for nearly two years as the operations lead and subject matter expert for processing and pressure oxidation.

Mr. Rissmiller, Perpetua's vice-president of human resources, brings vast experience in building and managing teams across mining and energy projects in domestic and international settings. Mr. Rissmiller's years of experience in talent acquisition will lend immediate value to Perpetua as the company grows its team to meet the demands of construction.

Mr. Fazzini, CA, CPA, CFA, joins the Perpetua team as vice-president of investor relations after 15 years working in both corporate and capital markets roles. Mr. Fazzini brings a diverse background including institutional equity sales, mining equity research and executive management roles at mineral development companies across the Americas. Given his extensive experience in investor engagement and equity sales, Mr. Fazzini's role will focus on direct engagement with global institutional and retail investors.

Michael Wright, vice-president of projects, submitted his resignation on Dec. 3, 2025, for personal family reasons. He and the company have entered into a consulting agreement for Mr. Wright to provide continuing project development support through early March, 2026. The company thanks Mr. Wright for his leadership in moving the Stibnite gold project through the development of a highly qualified owner's delivery team and the completion of basic engineering. Over the last two years, Mr. Wright's work as vice-president, projects, has supported Perpetua Resources in successfully raising over $800-million in equity and in commencing early works construction which began in October, 2025.

About Perpetua Resources Corp. and the Stibnite gold project

Perpetua Resources, 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 Stibnite gold 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. Antimony trisulphide from Stibnite is the only known domestic reserve of antimony that can meet United States defence needs for many small arms, munitions and missile types.

We seek Safe Harbor.
