VANCOUVER, BC, Sept. 4, 2025 — Integra Resources Corp. (“Integra” or the “Company”) (TSXV: ITR) (NYSE American: ITRG) is pleased to announce that the updated Mine Plan of Operations (“MPO”) for the DeLamar Project (“DeLamar” or the “Project”) has been determined by the United States Bureau of Land Management (“BLM”) to have met the content requirements of Title 43, Subpart 3809 of the Code of Federal Regulations (CFR).
Highlights
- The BLM’s determination of administrative completeness is a critical permitting milestone for DeLamar and reflects nearly three years of environmental baseline studies, initial engineering design, and mine plan optimization. The MPO will serve as the basis for the BLM’s environmental review under the National Environmental Policy Act (NEPA).
- The updated MPO was submitted earlier in 2025 and underwent the initial completeness review prescribed by the CFR. Integra worked closely with the BLM to address comments on the MPO to achieve this milestone.
- The updated MPO incorporates several refinements, including:
- Responses to agency comments and concerns.
- Prioritization of mine features on previously disturbed ground and relocation of selected features to reduce potential impacts to surface and water quality.
- Leveraging processing capacity at Integra’s Florida Canyon Mine to reduce ore processing and electrical power demands at DeLamar.
- Incorporation of Project updates from the ongoing Feasibility Study for DeLamar, with results expected to be announced in Q4 2025.
- Next steps include the BLM developing the Project schedule and publishing the Notice of Intent (“NOI”), which will allow work on the Environmental Impact Statement (“EIS”) to commence. The NOI begins formal engagement with cooperating agencies and stakeholders.
- DeLamar is one of a small number of gold-silver development projects in the Western United States actively advancing through the NEPA mine permitting process, underscoring the Project’s scarcity value.
- Integra recently entered a Relationship Agreement with the Shoshone-Paiute Tribes of the Duck Valley Indian Reservation, establishing a long-term partnership for DeLamar. Details are available here.
George Salamis, President, CEO and Director of Integra, commented: “The acceptance of the updated MPO for DeLamar highlights the quality and scarcity value of the DeLamar Project. Incorporating several years of environmental baseline studies, initial engineering design, and detailed descriptions of mining and reclamation activities, the acceptance of the refined MPO represents a major milestone on the path to permitting mining activities at DeLamar. This permitting achievement, together with the Relationship Agreement with the Shoshone-Paiute Tribes, demonstrates Integra’s commitment to advancing DeLamar toward a production decision. We look forward to continuing to work with the BLM through the NEPA process and remain committed to responsible mining practices, environmental protection, and serving community interests.”
Next Steps
The BLM will publish the NOI in the Federal Register to notify government agencies and the public about the proposed actions at DeLamar. The NOI is a formal announcement of intent to prepare an EIS as defined by NEPA and will be followed by a public scoping process engaging federal, state, and local agencies, Tribal Nations, stakeholders, and the public to identify issues and concerns. After scoping, an EIS document will be prepared.
The EIS will analyze potential environmental effects from project implementation on resources including air, water, wildlife habitat, land use, Native American concerns, socio-economics, visual resources, cultural resources, vegetation, soils, recreation, range resources, and potential human health risks. It will also evaluate reasonable alternatives to the proposed action to minimize adverse effects and prevent undue degradation.
Concurrently, the Company will continue work on various permits required prior to construction, including: a groundwater Point of Compliance Permit, an Idaho Pollution Discharge Elimination System Permit, a Cyanidation Permit, an Air Quality Permit to Construct, and approvals under Section 404 of the Clean Water Act with the U.S. Army Corps of Engineers.
The Company continues to engage Tribal Nations as it advances toward the Programmatic Agreement (“PA”) process. The PA is a formal agreement between the Company, governmental agencies, and Tribal Nations that provides a framework for identifying, managing, and mitigating potential impacts on culturally sensitive areas or historical sites.
