Perpetua Resources, which is developing the open-pit Stibnite gold project in the Stibnite-Yellow Pine district of central Idaho, has tapped Hatch as its engineering, procurement, and construction management (EPCM) contractor following a highly competitive review process.
Perpetua officials said the move is significant in the project’s timeline, as EPCM work will allow it to transition from planning to development ahead of a final investment decision expected in the spring of 2026. It also strengthens Perpetua’s readiness to responsibly deliver the project, the developer said.
Under the EPCM model, Hatch will be responsible for a comprehensive process plant and site infrastructure engineering and design; procurement management for all major site equipment and systems; construction management across the full process facility scope and other site infrastructure; and integrated project controls, reporting, and performance management standards.
The selection of Hatch is ideal for Perpetua in that the contractor firm has global expertise in pressure oxidation technology and metallurgical processing facilities. Hatch, on the other hand, is planning to deploy an integrated project team for Stibnite, which has an extensive track record of delivering mining and metallurgical facilities similar in scale and scope.
“Hatch brings the depth, discipline, and proven execution capability required to responsibly deliver the Stibnite gold project,” said Jon Cherry, president and CEO, Perpetua.
“Their experience with sophisticated mining and metallurgical facilities in the United States will play a critical role in advancing Stibnite to the next phase of development. Today’s decision reflects our commitment to a robust construction strategy that combines top-tier engineering and project management while serving our national interest.”
“Perpetua’s vision for Stibnite aligns with our belief that world-class projects demand world-class execution,” said John Bianchini, Hatch chair and CEO.
“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.”
Stibnite remains the only known domestic reserve of antimony capable of meeting U.S. defense requirements for munitions, according to Perpetua data, and 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.
