Perpetua Resources selects Hatch as EPCM for Stibnite Gold Project
Boise, Idaho – Perpetua Resources Corp. (Nasdaq: PPTA / TSX: PPTA) (“Perpetua Resources” or “Perpetua” or the “Company”) today announced that it has selected Hatch Ltd. (“Hatch”) as the Engineering, Procurement, and Construction Management (“EPCM”) contractor for the Stibnite Gold Project (“SGP” or “Project”). The appointment of Hatch follows a highly competitive review process and marks a major milestone in Perpetua’s transition from planning to development, ahead of a final investment decision expected in the spring of 2026. The EPCM selection strengthens Perpetua’s readiness to responsibly deliver one of the most strategically important mining projects in the United States.
“Hatch brings the depth, discipline and proven execution capability required to responsibly deliver the Stibnite Gold Project. Their experience with complex mining and metallurgical facilities, including projects in the United States, reinforces our confidence that Stibnite is ready for the next phase of development. Today’s decision reflects our commitment to a disciplined construction strategy that combines best-in-class engineering, commercial rigor, and the national interest.”
— Jon Cherry, president and CEO, Perpetua Resources
Under the EPCM agreement, Hatch will deploy an integrated project team with an extensive track record of delivering complex facilities similar in scale and scope to the Stibnite Gold Project. The Company’s internationally recognized expertise in pressure oxidation technology and decades-long record of successfully executing large-scale mining and processing infrastructure across North America made Hatch the clear partner of choice for the SGP.
“Perpetua’s vision for Stibnite aligns with our belief that world-class projects demand world-class execution. Our team understands the strategic importance of domestic mineral supply chains and the opportunity at Stibnite to bring modern engineering, responsible construction, and operational excellence together in service of U.S. industry and national resilience. We are proud to partner with Perpetua and are committed to safely and efficiently delivering this project.”
— John Bianchini, chair and CEO, Hatch
Under the EPCM model, Hatch will be responsible for:
- Comprehensive process plant and infrastructure engineering and design
- Procurement management for all major equipment and systems
- Construction management across the full process facility scope
- Integrated project controls, reporting, and performance management standard
This comprehensive mandate ensures continuity of execution, transparent governance, and predictable delivery outcomes—key priorities for Perpetua, its stakeholders, and project financing partners.
Perpetua conducted an expedited, yet rigorously governed, selection process guided by a weighted evaluation matrix. Only firms with demonstrated technical depth, commercial competitiveness, and previous engagement with the Stibnite Gold Project were invited to bid. Hatch emerged as the clear leader across commercial, technical, and execution-readiness criteria.
The selection of Hatch advances Perpetua’s construction readiness and supports ongoing financing efforts through the U.S. Export-Import Bank. All current contractors supporting the Project are committed to ensuring a smooth and collaborative transition as Hatch assumes EPCM responsibilities.
Stibnite remains the only known domestic reserve of antimony capable of meeting U.S. defense requirements for munitions. The Project’s unique combination of critical mineral production and legacy mine site restoration positions it as a strategic asset for national supply chain resilience.
