Key Terms

notice of intent, national environmental policy act, nepa, environmental impact statement, +4 more

8 terms

notice of intent regulatory

"has published the Notice of Intent ("NOI") in the Federal Register"

A notice of intent is a formal written announcement that an organization plans to take a specific action—such as filing legal claims, seeking regulatory approval, issuing securities, or starting a procurement process. For investors it matters because it signals a likely future event that could change a company’s costs, revenues, risk profile or ownership; think of it like a heads-up that a major move is being prepared so stakeholders can anticipate and reassess their positions.

national environmental policy act regulatory

"initiating the National Environmental Policy Act ("NEPA") review process"

A U.S. law that requires federal agencies to evaluate and disclose the likely environmental effects of major projects and decisions before they proceed. For investors, that review can delay approvals, add compliance costs, or change project plans—like a required safety inspection that can uncover problems or require fixes before construction continues—so NEPA processes are a key source of timing, cost and legal risk for projects involving federal permits or funding.

nepa regulatory

"initiating the National Environmental Policy Act ("NEPA") review process"

The National Environmental Policy Act (NEPA) is a U.S. law that requires federal agencies to evaluate and report the environmental impacts of major projects, like permitting, construction, or resource development. For investors, NEPA is important because its reviews and required studies can delay, alter, or block projects—much like a safety inspection that must be passed before a vehicle is allowed on the road—affecting timelines, costs and the potential revenue of affected companies.

environmental impact statement regulatory

"commencing preparation of an Environmental Impact Statement ("EIS")"

An environmental impact statement is a formal report that evaluates the likely effects a proposed project or plan will have on air, water, land, wildlife and local communities; it lays out potential harms, proposed mitigation measures, and alternatives. Think of it as a project’s environmental report card and repair plan: regulators use it to decide permits, and investors use it to assess delays, extra costs, legal risks and reputation exposure tied to environmentally sensitive issues.

record of decision regulatory

"publish the final EIS and Record of Decision ("ROD") in the second half"

A record of decision is an official written statement from a government regulator that explains and finalizes its approval or denial of a proposed project after reviewing environmental and legal factors. For investors, it matters because it removes a major regulatory uncertainty — like a referee’s final whistle — allowing a project to move forward, be funded, or be halted, which can change timelines, costs, and potential liabilities.

fast-41 regulatory

"included in the U.S. Federal Permitting Improvement Steering Council's FAST-41"

A FAST-41 designation comes from a U.S. law that sets up a coordinated, time-lined review process for large federal infrastructure projects, aiming to reduce delays by having agencies work together and meet clear deadlines. For investors, it matters because projects with FAST-41 oversight are likelier to reach permits and construction on schedule, reducing the risk of costly hold-ups much like a traffic controller clearing lanes so a convoy can move without unexpected stops.

federal permitting dashboard regulatory

"Based on the publicly accessible Federal Permitting Dashboard, the federal"

An online system that gathers and shows the status of federal permits and related approvals across multiple government agencies in one place, often with timelines, maps, and contact information. For investors, it acts like a delivery-tracking page for big projects: it reveals where approvals are held up, how long permitting may take, and the regulatory risk and scheduling uncertainty that can affect project costs, revenue timing and investment decisions.

heap leach technical

"establish DeLamar as a premier heap leach project in the Great Basin."

Heap leach is a mining method where crushed ore is piled into a heap and a liquid is dripped or sprayed over it to dissolve valuable metals, which are then collected from the runoff. Investors care because it is a lower-cost, scalable way to produce metals like gold or copper, but it also affects project timelines, recovery rates, capital needs and environmental or regulatory risk — like choosing a cheap, slow way to extract juice from a fruit versus pressing it quickly.

VANCOUVER, BC, May 29, 2026 /PRNewswire/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR) (NYSE American: 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.

U.S. Senator Mike Crapo (Idaho) stated: "Idaho has a long and responsible mining history, and projects like DeLamar can help strengthen America's domestic supply chains while supporting good-paying jobs in rural communities. Today's announcement marks an important step forward in the federal permitting process, and I encourage continued coordination among federal and state agencies, local stakeholders and the community as the review moves forward."

"Today's announcement is a critical step in securing our mineral supply chain and brings us closer to delivering high-quality jobs to Idaho," said U.S. Senator James Risch (Idaho). "While this is a major milestone, it is vital we in Congress work to cut red tape and streamline the permitting process so projects like this can move forward expeditiously."

"The DeLamar Project will advance domestic gold and silver production, create great employment and economic opportunities in Owyhee County, and help reduce our nation's reliance on foreign countries for the minerals essential to our supply chains. I'm pleased to see the Notice of Intent announced for this project, which will help strengthen rural Idaho communities and bolster America's ability to produce critical resources here at home," said U.S. Congressman Russ Fulcher (Idaho-01)

George Salamis, President, Chief Executive Officer and Director of Integra, commented: "The publication of the NOI in the Federal Register is a significant step forward for the Company. This achievement reflects more than seven years of technical work, environmental baseline studies, and ongoing engagement with stakeholders, Tribal Nations, and local communities. Since 2021, the Company has engaged with over 49,000 stakeholders and held more than 1,400 events, tours, and open houses to share our vision for revitalizing DeLamar. The Company looks forward to working alongside federal and state agencies to advance the domestic production of gold and silver in Idaho and establish DeLamar as a premier heap leach project in the Great Basin."

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. More information on FAST-41 projects can be found on the Federal Permitting Dashboard: www.permits.performance.gov
