INTEGRA ANNOUNCES SELECTION OF THE DELAMAR HEAP LEACH PROJECT FOR THE FAST-41 PERMITTING TRANSPARENCY PROGRAM

Integra Resources Corp.'s DeLamar heap-leach project located in southwestern Idaho has been selected for inclusion in the U.S. Federal Permitting Improvement Steering Council FAST-41 transparency projects program.

Highlights:

• The FAST-41 transparency projects program is a federal permitting framework designed to improve interagency co-ordination and increase transparency. Key benefits include:
  • Enhanced visibility and predictability: Agencies must develop and maintain a project-specific timetable for all required federal environmental review and permitting actions. Scheduled and actual time frames for these actions are publicly displayed.
  • Improved co-ordination: Project sponsors will be designated with a dedicated project adviser from the permitting council, who will monitor the advancement of the project while maintaining active engagement and co-ordination across federal agencies.
  • Increased accountability: The permitting council provides oversight to ensure that federal agencies adhere to established timetables, including quarterly reports to Congress detailing agency compliance with transparency projects.
• Based on DeLamar's permitting timeline defined by the U.S. Bureau of Land Management (BLM) and posted to the federal permitting dashboard on Jan. 13, 2026, the federal permitting process anticipates a record of decision (ROD) being published in Q3 2027, reflecting an efficient 15-month National Environmental Policy Act (NEPA) process.

George Salamis, president, chief executive officer and a director of Integra, commented: "DeLamar is Integra's flagship gold-silver development asset and a high-quality growth opportunity in a Tier 1 jurisdiction. The project's inclusion on the federal permitting dashboard represents a meaningful milestone in DeLamar's advancement. The company is grateful for the permitting council's selection, which provides enhanced transparency into federal environmental reviews and authorizations. Integra remains committed to a rigorous, inclusive and collaborative NEPA process, supported by many years of stakeholder engagement, environmental baseline studies and technical refinement of the mine plan design. With the BLM's anticipated 15-month NEPA review period, we believe DeLamar is well positioned to advance efficiently through permitting. Once in production, DeLamar is expected to be a cornerstone asset supporting Integra's strategy of building a high-quality portfolio of heap-leach operations in the Great basin of the United States."

Permitting council and FAST-41 projects

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 on-line 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.

DeLamar project overview (all amounts in 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 southwestern 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, prefeasibility 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 a high rate of return. The FS outlines total production of 1.1 million ounces of gold equivalent 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 AuEq. The project generates an after-tax net present value (discounted at 5 per cent) of $774-million with an after-tax internal rate of return (IRR) of 46 per cent at base-case gold and silver prices of $3,000 per ounce and $35 per ounce, respectively. After-tax NPV (discounted at 5 per cent) improves to $1.7-billion and after-tax IRR improves to 89 per cent using recent gold and silver prices of $4,250 per ounce and $60 per ounce, respectively. Refer to the 2025 DeLamar feasibility study announcement news release from Dec. 17, 2025.

The FS technical report will be filed on SEDAR+ and EDGAR by Feb. 2, 2026.
