Integra Resources Reveals Federal Permitting Schedule For Delamar Heap Leach Project; BLM-Defined Schedule Contemplates Publication Of A NOI In The Q2 2026

Integra Resources Corp. ("Integra" or the "Company") (TSXV:ITR) (NYSE:ITRG) is pleased to announce that the United States Bureau of Land Management ("BLM") has formally established a federal permitting schedule under the National Environmental Policy Act ("NEPA") for the Company's DeLamar Heap Leach Project ("DeLamar" or the "Project") located in southwestern Idaho. For the first time, DeLamar benefits from a clearly defined, fact-based NEPA pathway endorsed by the BLM, providing enhanced visibility into the federal permitting process and materially reducing permitting uncertainty.

The BLM-defined schedule contemplates publication of a Notice of Intent ("NOI") in the second quarter of 2026, followed by an anticipated 15-month NEPA review period, culminating in the issuance of an Environmental Impact Statement ("EIS") and Record of Decision ("ROD") in the third quarter of 2027. This timeline is materially more efficient than previously contemplated permitting scenarios and represents a significant advancement in the Project's development trajectory.

When combined with the recently released Feasibility Study, demonstrating robust gold- and silver-driven economics, DeLamar is now materially de-risked and advancing toward a shovel-ready development profile from both a technical and permitting perspective. DeLamar stands out as one of a limited number of advanced-stage gold-silver development projects in the United States currently benefiting from a defined and expedited federal permitting timeline.
