Integra Resources Corp. (NYSE American: ITRG) appointed Ausenco Engineering USA South Inc. as lead engineering partner for detailed engineering activities at its DeLamar Project in southwestern Idaho. Ausenco retained SLR Consulting to provide specialized heap leach engineering, metallurgy, and mine planning expertise for the project.

The appointment coincides with the launch of the public scoping and stakeholder engagement period of the National Environmental Policy Act review process. The United States Bureau of Land Management published the Notice of Intent in the Federal Register on May 29, 2026, starting a 30-day public scoping period.

Integra expects the final Environmental Impact Statement and Record of Decision from the BLM in the second half of 2027. Detailed engineering work will continue through the first quarter of 2027, with long-lead procurement activities beginning in the second half of this year.

"Entering the detailed engineering phase at DeLamar is a major milestone for the Company," said George Salamis, president and chief executive officer of Integra. "The appointment of Ausenco strengthens the Company's position to advance DeLamar as the Company progresses through the NEPA process."

Chief Operating Officer Cliff Lafleur stated that the detailed engineering work and expected receipt of regulatory approvals will inform a construction decision for DeLamar.

Under the scope of work, Ausenco will lead detailed engineering and execution readiness activities including engineering design advancement, procurement planning, and project execution planning. SLR recently acquired Forte Analytical and Forte Dynamics, which prepared the feasibility study technical report for DeLamar dated February 2, 2026.

The information is based on a press release statement from the company.
