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 published the Notice of Intent ("NOI") in the Federal Register initiating the National Environmental Policy Act ("NEPA") review process for the DeLamar Project ("DeLamar" or the "Project") located in Idaho.

The publication of the NOI represents a significant milestone in the advancement of DeLamar, formally commencing preparation of an Environmental Impact Statement ("EIS") and initiating the public scoping and stakeholder engagement process under NEPA. Following public scoping and the associated 30-day comment period, the BLM will conduct its environmental analysis and is expected to publish the final EIS and Record of Decision ("ROD") in the second half of 2027.

Permitting Council and Fast-41 Projects:

DeLamar has been included in the U.S. Federal Permitting Improvement Steering Council's FAST-41 Transparency Projects Program (see news release dated January 14, 2026). This program is a federal permitting framework designed to improve interagency coordination and increase transparency during the NEPA process. Based on the publicly accessible Federal Permitting Dashboard, the federal permitting process anticipates a final EIS and ROD to be published in Q3 2027, establishing a 15-month NEPA process for DeLamar.

Established under Title 41 of the Fixing America's Surface Transportation ("FAST") Act (known as "FAST-41") in 2015, the Permitting Council consists of the Executive Director and Deputy Secretary level representatives from 13 federal agencies as well as the Director of the Office of Management and Budget and the Chair of the Council on Environmental Quality. The Permitting Council brings federal agencies and stakeholders together to improve the permitting process for critical infrastructure projects.

FAST-41 Transparency Projects are projects directed by the Permitting Council Executive Director to be posted on the Federal Permitting Dashboard, a public online resource for information on FAST-41 projects and the environmental review and permitting processes.
