Integra Resources Receives Final Approval of Exploration Plan of Operations for Wildcat Deposit, Advancing Nevada North Project Toward Pre-Feasibility Study

The approval of the Exploration Plan of Operations for the Wildcat Deposit represents a major permitting milestone for Integra Resources' Nevada North Project, enabling expanded exploration activities and advancing the project from the 2023 Preliminary Economic Assessment stage toward a Pre-Feasibility Study targeted for completion in the second half of 2027.

Company Overview

Integra Resources Corp. (TSXV: ITR | NYSE American: ITRG) is a growing precious metals producer in the Great Basin of the Western United States. The Company's principal operating asset is the Florida Canyon Mine in Nevada. Integra is advancing two flagship development-stage heap leach projects: the past-producing DeLamar Project in southwestern Idaho and the Nevada North Project in western Nevada. The Company creates sustainable value through successful mining operations, efficient project development, disciplined capital allocation, and strategic M&A. 

Wildcat EPO Approval: Regulatory Framework & Operational Flexibility

Integra Resources received the NEPA Decision Record and Reclamation Permit on April 29, 2026, approving the Exploration Plan of Operations (EPO) for the Wildcat Deposit located in Pershing County, Nevada. The NEPA Decision Record, submitted by the United States Department of the Interior Bureau of Land Management (BLM) Humboldt River Field Office, authorises 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), authorises expanded exploration and development activities at Wildcat under a comprehensive EPO and establishes appropriate financial assurance based on an agency-reviewed reclamation cost estimate.

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 programmes. 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 authorisation. This expanded authorisation 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.

Nevada North Project: Dual-Deposit Portfolio & Development Pathway

The Nevada North Project, comprised of the Wildcat and Mountain View deposits, represents a key growth pillar for Integra in Nevada and is situated approximately 26 miles west of the Company's producing Florida Canyon Mine. 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, optimised mine planning, and enhanced Project economics. 

Self-Funded Growth Platform: Florida Canyon Cash Flow Underpinning Multi-Asset Advancement

With the successful transition to gold production following the acquisition of the Florida Canyon Mine, Integra has established a strong, internally funded 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 ongoing technical studies, drilling, and permitting initiatives. This self-funded model is expected to continue underpinning Integra's strategy of advancing multiple high-quality projects within the Great Basin.

George Salamis, President, Chief Executive Officer and Director of Integra, commented:

"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 underway to progress from the 2023 PEA to a PFS, we are well-positioned to continue unlocking value from this emerging gold district."

Salamis continued:

"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, multi-asset gold platform in the US."

Next Steps

Integra is advancing Nevada North from the 2023 PEA stage toward a PFS, with completion targeted for the second half of 2027. The PFS is expected to incorporate updated resource models, optimised mine planning, and enhanced Project economics. Forthcoming modifications to the approved Wildcat EPO will facilitate more in-depth hydrogeologic and other field studies that will build on preliminary data collected under notice-level authorisation. The Company continues to advance technical studies, drilling, and permitting initiatives across its Nevada and Idaho asset portfolio, supported by cash flow generated from the Florida Canyon Mine.
