INTEGRA RECEIVES FINAL APPROVAL OF EXPLORATION PLAN OF OPERATIONS FOR THE WILDCAT DEPOSIT, ADVANCING NEVADA NORTH PROJECT TOWARD PRE-FEASIBILITY STUDY

Integra Resources Corp. has received the National Environmental Policy Act (NEPA) decision record and reclamation permit approving its exploration plan of operations (EPO) for the Wildcat deposit, located in Pershing county, Nevada. This approval represents a significant permitting milestone for this component of the company's Nevada North project, which includes both the Wildcat and Mountain View gold deposits, situated approximately 26 miles west of the company's producing Florida Canyon mine.

The NEPA decision record, submitted by the United States Department of the Interior Bureau of Land Management (BLM) Humboldt River Field Office, authorizes the final environmental assessment and the associated finding of no significant impact (FONSI) for the Wildcat deposit. The reclamation permit, granted by the Nevada Division of Environmental Protection's Bureau of Mining Regulation and Reclamation (BMRR), authorizes expanded exploration and development activities at Wildcat under a comprehensive EPO and establishes appropriate financial assurance based on an agency-reviewed reclamation cost estimate. This milestone follows the previously announced approval of an EPO for the Mountain View deposit earlier this year, further demonstrating continued permitting advancement across the broader Nevada North project portfolio.

Highlights:

• Major permitting milestone: Approval of the Wildcat EPO marks a significant step forward in advancing Nevada North toward development.
• Expanded operational flexibility: The EPO allows for a significant increase in the scale and flexibility of permitted exploration disturbance, enabling more efficient and comprehensive exploration and site activities compared with prior, more limited exploration authorizations.
• Advancing toward PFS (prefeasibility study) and advanced permitting: Work is under way to advance Nevada North from the 2023 preliminary economic assessment (PEA) stage toward a PFS, targeted for completion in H2 (second half) 2027.
• Strategic location: Nevada North is located approximately 26 miles west of the Florida Canyon mine, highlighting potential future operational synergies and regional consolidation opportunities.
• Supportive United States regulatory environment: The approval underscores continued progress within a constructive permitting framework in Nevada, one of the world's leading mining jurisdictions.

George Salamis, president, chief executive officer and director of Integra, commented:

"The approval of the exploration plan of operations for Wildcat is a pivotal milestone for Integra and a strong endorsement of the quality and potential of our Nevada North project. Alongside the previously permitted Mountain View deposit, this achievement reflects meaningful and sustained permitting progress in a highly supportive jurisdiction. The project's proximity to our Florida Canyon operation further reinforces the strategic importance of Nevada North within our growing U.S. portfolio. This approval significantly enhances our ability to execute larger-scale, more efficient exploration and development programs at Wildcat as we advance Nevada North toward the next stage of technical and economic evaluation. With work now under way to progress from the 2023 PEA to a PFS, we are well positioned to continue unlocking value from this emerging gold district.

"Importantly, Florida Canyon delivers consistent gold production and cash flow, enabling us to internally fund advancement across our broader portfolio. This includes continued permitting and technical progress at both the DeLamar project and Nevada North, reinforcing our strategy of building a scalable, multiasset gold platform in the U.S."

Nevada North project advancement

The Nevada North project, comprising the Wildcat and Mountain View deposits, represents a key growth pillar for Integra in Nevada. The project was the subject of a PEA completed in 2023, which outlined the potential for a scalable, open-pit, heap leach gold operation.

Integra is currently advancing technical studies and baseline work to support a PFS, with completion targeted for the second half of 2027. The PFS is expected to incorporate updated resource models, optimized mine planning and enhanced project economics.

With the successful transition to gold production with the acquisition of the Florida Canyon mine, Integra has established a strong, internally financed growth platform. Cash flow generated from the Florida Canyon mine is being reinvested into the advancement of the company's key development assets, including the DeLamar project in Idaho and the Nevada North project, supporting continuing technical studies, drilling and permitting initiatives. This self-financed model is expected to continue underpinning Integra's strategy of advancing multiple high-quality projects within the Great basin.

About the Wildcat exploration plan of operations

The approved EPO and reclamation permit provide a comprehensive framework for exploration and site activities at Wildcat, including the construction of drill roads and pads and the execution of expanded drilling programs. The reclamation permit includes an initial phase of disturbance, with provisions for additional phased expansion subject to bonding and regulatory requirements. Forthcoming modifications to the EPO will facilitate more in-depth hydrogeologic and other field studies that will build on preliminary data collected under notice-level authorization.

This expanded authorization represents a meaningful evolution from earlier, more limited exploration permits and is expected to materially improve the company's ability to advance the project efficiently.
