As part of the engagement, Ausenco has retained SLR Consulting ("SLR"), which brings specialized heap leach engineering, metallurgy, and mine planning expertise to the Project. The start of detailed engineering marks a significant step in project development for DeLamar and coincides with the launch of the public scoping and stakeholder engagement period of the National Environmental Policy Act ("NEPA") review process.

The Company announced on May 29, 2026, that the United States Bureau of Land Management ("BLM") has published the Notice of Intent ("NOI") in the Federal Register. The publication of the NOI started the 30-day public scoping and stakeholder engagement period of the NEPA process. Concurrent with the NEPA process, Ausenco and Integra will advance detailed engineering at DeLamar, with the final Environmental Impact Statement ("EIS") and Record of Decision ("ROD") from the BLM anticipated in the second half of 2027.
