INTEGRA ANNOUNCES FOURTH QUARTER AND FULL YEAR 2025 GOLD PRODUCTION RESULTS FROM FLORIDA CANYON MINE, ACHIEVING PRODUCTION GUIDANCE AND SIGNIFICANT CAPITAL REINVESTMENT

VANCOUVER, BC, Jan. 26, 2026 /PRNewswire/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV:ITR, NYSE:ITRG) is pleased to provide an interim operational update for the fourth quarter ended December 31, 2025 (the "fourth quarter 2025" or "Q4 2025"). The Company plans to release its fourth quarter and full year 2025 financial results after market close on Tuesday, March 24, 2026, followed by a conference call hosted by senior management on Wednesday, March 25, 2026 at 11:00 AM Eastern Time / 8:00 AM Pacific Time.

(All amounts in United States ("U.S.") dollars as at December 31, 2025, unless otherwise stated)

2025 Operational Highlights:

• The Florida Canyon Mine ("Florida Canyon") delivered 70,927 ounces of gold, meeting full year production guidance of 70,000–75,000 gold ounces.
• The Company completed approximately $60 million of planned capital investment at Florida Canyon across mining, infrastructure, equipment, and growth drilling.
• Numerous significant advancements were made relating to mine flexibility, infrastructure, and equipment, positioning Florida Canyon for improved production, consistency, and growth in 2026.
• Cash flow generated by Florida Canyon supported the achievement of several key initiatives in 2025:
  • Major mine reinvestment at Florida Canyon ahead of an updated technical report in mid-2026, incorporating an updated mineral reserve and resource statement and life-of-mine mine plan.
  • Advanced the DeLamar Project ("DeLamar") through Feasibility Study and into Federal mine permitting.
  • Advanced Nevada North Project ("Nevada North") toward a Pre-Feasibility Study and completed important pre-permitting activities.
  • Supported corporate level costs and strengthened balance sheet by significantly increasing annual cash balance and completed full retirement of convertible debt facility.

George Salamis, President, CEO and Director of Integra commented: "2025 marked a pivotal year for Integra as the Company successfully completed its first full year of production at Florida Canyon, while executing a deliberate and capital-intensive reinvestment strategy. In our first full year as a gold producer, we met our annual production guidance while advancing several foundational initiatives, namely a heap leach pad expansion, significant capitalized stripping, growth drilling, and a wide-spanning fleet modernization initiative. These initiatives were specifically designed to improve operational reliability and flexibility, supporting long-term operating performance and growth.

Importantly, cash flow from Florida Canyon funded not only these mine-site investments, but also technical advancement, de-risking and advanced permitting initiatives at DeLamar and Nevada North, validating the strategic rationale behind acquiring Florida Canyon in late 2024. With major capital projects now well underway, Florida Canyon enters 2026 with improved infrastructure, enhanced mining capability, and a stronger platform for consistent production and cash generation to fund other organic growth initiatives.

Following the release of 2026 guidance, expected later in the first quarter, we look forward to sharing our long-term vision for Florida Canyon in mid-2026, supported by an updated reserve and resource estimate and life-of-mine plan, which we believe will highlight an exciting future for the Florida Canyon operation."

Fourth Quarter and Full Year 2025 Florida Canyon Mine Operational Update

Florida Canyon produced 12,864 ounces of gold and sold 12,920 ounces of gold during the fourth quarter 2025. Production during the quarter was derived from gold placed on the Phase IIIa leach pad, together with residual recovery from Phases I and II. Quarterly production reflected a one-time, temporary reduction in solution flow rates resulting from a liner tear in a solution pond identified during the fourth quarter. The liner was fully repaired by mid-November with no solution releases and no environmental impact. Solution flow rates were restored to normal levels prior to year-end. Preventative measures, including an additional protective liner and improved access to the affected area for personnel and equipment, have been implemented for more effective response in the unlikely event this occurs again in the future. Importantly, gold ounces associated with the reduced solution flow during the quarter were deferred, not lost, and are expected to remain recoverable through continued leaching. Based on leach pad inventories and normalized solution flow, the Company expects the majority of ounces deferred during the fourth quarter—estimated at approximately 2,000 to 3,000 ounces—to be recovered through ongoing leaching throughout 2026.

Despite lower fourth quarter production relative to earlier quarters, Florida Canyon delivered 70,927 ounces of gold for the full year, achieving Integra's 2025 gold production guidance. Recovery rates for the year remained consistent with expectations, and the modest fourth quarter variance reflects timing rather than any change in ore quality or metallurgical performance.

Mining activities during the fourth quarter at Florida Canyon were executed in line with plan, with higher ore placement to the leach pads and reduced waste movement following earlier capitalized stripping campaigns. As a result, the strip ratio declined to 0.71 in the fourth quarter, supporting improved mining efficiency as the mine enters 2026.

During the quarter, Florida Canyon completed construction of the Phase IIIb heap leach pad, with regulatory approval to begin leaching expected in the first quarter of 2026. The Company also advanced its fleet revitalization program with refurbishment of legacy haul trucks and loaders, while commissioning four new machines: a Hitachi EX3600 front shovel, a Caterpillar 992HL loader, and two Caterpillar 785 haul trucks. An additional six Caterpillar 785 haul trucks are expected to be commissioned in the first half of 2026. The upgraded fleet is expected to reduce reliance on expensive rental equipment, enhance productivity, and lower mining costs per tonne over the coming years.

The Company also continued its growth focused drilling program at Florida Canyon in the fourth quarter, completing approximately 3,100 meters of reverse circulation and sonic drilling. The 2025 program, originally planned for approximately 10,000 meters, was subsequently expanded to 16,000 meters due to its initial success. Drilling is focused on three key areas: (1) evaluating near-surface oxide potential from historical waste areas; (2) expanding in-situ resources between existing open pits; and (3) testing lateral extensions and conducting in-pit infill drilling. The program was specifically designed to support future mineral resource and reserve updates aiming to extend mine life at Florida Canyon. The 2025 drill program at Florida Canyon will support a mineral resource and reserve update and a revised life-of-mine plan in mid-2026.

The Company expects to release 2026 production and cost guidance for Florida Canyon in late February 2026.

Fourth Quarter 2025 Financial Position

The fourth quarter 2025 marked a capital intensive period across the Company's portfolio of assets and at the corporate level with several key activities during the quarter:

• Florida Canyon: Approximately $20 million was allocated to sustaining and non-sustaining capital including the completion of construction of the Phase IIIb heap leach pad, capitalized waste stripping, initial cash payments on new mining equipment, and an expanded growth drilling program.
• DeLamar and Nevada North: Approximately $6 million was allocated to complete significant de-risking activities including feasibility studies, permitting work, and hydrogeological drilling.
• Corporate: Approximately $8 million was allocated to Florida Canyon tax remittances and corporate activities including accrued interest and standby charges related to the conversion and retirement of the convertible debt facility, and general and administrative expenses.
