Perpetua Resources Idaho, Inc. (PRII) entered into a second amendment to its existing EPCM agreement with Hatch Ltd. The amendment covers the design, engineering, and supply of proprietary equipment, including autoclaves, flash vessels, and vent gas cyclones. The fixed aggregate purchase price for this equipment is $32.1 million. The agreement establishes specific warranty, intellectual property, and liability terms distinct from the broader EPCM services contract. The purchase price excludes on-site supervision, installation, and commissioning, which will be handled via future change orders.
