VANCOUVER, BC, Jan. 12, 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 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.

George Salamis, President, CEO and Director of Integra, commented: "The establishment of a BLM-defined federal permitting timeline marks a transformational milestone for both DeLamar and Integra. For the first time, the Project has a clear, accelerated, and fact-based pathway through the NEPA process, materially reducing one of the most significant barriers to mine development in the United States. This schedule is meaningfully shorter than previously anticipated and substantially improves project certainty, capital efficiency, and time-to-value for our shareholders.

Combined with the recently released DeLamar Feasibility Study, this milestone positions the Project among the most advanced and de-risked large-scale precious metals development opportunities in the United States. With strong economics, early free cash flow potential, and a defined federal permitting runway, we believe DeLamar is approaching a build-ready profile and is well positioned to deliver long-term value in a constructive gold and silver market environment."

Permitting Schedule Details and Next Steps

Since the Company's acquisition of the DeLamar Project, nearly a decade of comprehensive environmental baseline data collection, exploration, engineering studies, and mine plan development have been completed. This extensive work has resulted in a Project that is well advanced and well prepared for rigorous environmental review. Ongoing engagement with surrounding communities and regional Tribal Nations has provided valuable input and helped inform multiple iterations of Project refinement as it has progressed through successive review cycles.

Now that the federal permitting schedule has been established, the BLM will move to publish a NOI in the Federal Register to notify government agencies and the public of the proposed action at DeLamar. The NOI formally announces the BLM's intent to prepare an EIS in accordance with NEPA. Following publication of the NOI, a public scoping process will be conducted to engage federal, state, and local agencies, Tribal Nations, and the general public to identify issues and concerns associated with the Project. These issues will guide the development of reasonable alternatives designed to minimize adverse effects and prevent undue degradation.

Once scoping is complete, environmental impact analyses of the Project and a reasonable range of alternatives will be undertaken, culminating in preparation of the EIS. Through this process, elements of the Project may be refined and mitigation measures developed to reduce potential environmental impacts. In the EIS and accompanying ROD, anticipated in the third quarter of 2027, the BLM will identify a Preferred Alternative and any mitigation measures required for Project implementation. This mitigation is expected to include continued engagement with Tribal Nations and the development of a Programmatic Agreement ("PA"), a formal framework established among the Company, governmental agencies, and Tribal Nations to identify, manage, and mitigate potential impacts to culturally sensitive areas and historic properties.

Following completion of the NEPA process, a final revised Mine Plan of Operations ("MPO") will be prepared that incorporates the Preferred Alternative and all required mitigation measures.

While the EIS process is underway, the Company will continue to work with federal, state, and local regulatory agencies to advance the various permits required prior to construction and operation. These permits include a groundwater Point of Compliance Permit to protect beneficial uses of groundwater; an Idaho Pollution Discharge Elimination System Permit governing treated industrial wastewater discharges; a Cyanidation Permit for heap leach operations; an Air Quality Permit to Construct; and a Section 404 Clean Water Act Permit issued by the U.S. Army Corps of Engineers to assess impacts to aquatic resources and implement compensatory mitigation where required. An approved Reclamation Plan, supported by appropriate financial assurance, will also be required. Upon receipt of all necessary permits and posting of required bonding, the Project may proceed to construction.

DeLamar Project Overview

(All amounts in United States ("U.S.") dollars unless otherwise stated)

The past producing DeLamar Project, which includes the adjacent DeLamar and Florida Mountain gold and silver deposits, is located in Owyhee County in southwest Idaho. Since acquiring the Project in 2017, the Company has demonstrated significant resource growth and conversion while providing robust economic studies in its maiden Preliminary Economic Assessment, Pre-feasibility Study, and Feasibility Study ("FS") in late-2025. The 2025 FS for DeLamar confirmed robust economics for a low-cost, large-scale, conventional open pit oxide heap leach operation, with competitive operating costs and high rate of return. The FS outlines total production of 1.1 million ounces of gold equivalent ("AuEq") over a 10-year operating mine life (plus two years of residual leaching), resulting in an average annual production profile of 106,000 ounces AuEq per annum at a co-product mine-site All-in Sustaining Cost of $1,480 per ounce ("/oz") AuEq. The Project generates an after-tax Net Present Value ("NPV5%") of $774 million with an after-tax Internal Rate of Return ("IRR") of 46% at base case gold and silver prices of $3,000/oz and $35/oz, respectively. After-tax NPV5% improves to $1.7 billion and after-tax IRR to 89% using recent gold and silver prices of $4,250/oz and $60/oz, respectively.

Cautionary Note Regarding Non-GAAP Financial Measures

Alternative performance measures in this news release such as "cash cost", "AISC" and "free cash flow" are furnished to provide additional information. These non-GAAP performance measures are included in this news release because these statistics are used as key performance measures that management uses to monitor and assess performance of DeLamar, and to plan and assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standardized meaning within International Financial Reporting Standards ("IFRS") and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Cash Costs

Cash costs include site operating costs (mining, processing, site G&A), refinery costs and royalties, but excludes head office G&A and exploration expenses.  While there is no standardized meaning of the measure across the industry, the Company believes that this measure is useful to external users in assessing operating performance.

All-In Sustaining Cost

Site level AISC includes cash costs and sustaining and expansion capital, but excludes head office G&A and exploration expenses. The Company believes that this measure is useful to external users in assessing operating performance and the Company's ability to generate free cash flow from potential operations.

Free Cash Flow

Free cash flows are revenues net of operating costs, royalties, capital expenditures and cash taxes. The Company believes that this measure is useful to the external users in assessing the Company's ability to generate cash flows from the Project.
