VANCOUVER, BC, April 23, 2026 /PRNewswire/ - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR) (NYSE American: ITRG) is pleased to provide an interim operational update for the first quarter ended March 31, 2026 (the "first quarter 2026" or "Q1 2026") highlighting continued operational momentum, record mining rates, and a strengthened balance sheet.

The Company plans to release its first quarter 2026 financial results after market close on Monday May 11, 2026, followed by a conference call hosted by senior management on Tuesday, May 12, 2026 at 11:00 AM Eastern Time / 8:00 AM Pacific Time. 

(All amounts in United States ("U.S.") dollars as at March 31, 2026, unless otherwise stated.)

Q1 2026 Operational Highlights:

• The Company mined 3.0 million ("M") tonnes of ore and 3.9 M tonnes of waste at a strip ratio of 1.30 at the Florida Canyon Mine ("Florida Canyon" or the "Mine"). As a result, mining rates averaged 76,800 total tonnes per day ("tpd") which is a record for the Mine and its operations. 
• The Florida Canyon Mine produced 12,635 ounces of gold and sold 12,518 ounces of gold in the quarter.
• The Company commissioned six new Caterpillar 785 haul trucks during the quarter, materially enhancing mining capacity and supporting higher sustained mining rates going forward.
• The Company raised $61 M through a bought deal public offering in Q1 2026 significantly strengthening the Company's balance sheet and funding near-term growth initiatives at the DeLamar Project (the "DeLamar Project" or "DeLamar"). Net proceeds are expected to be used to commence pre-production expenditures at the DeLamar Project and funded the acquisition of a strategic land position near the DeLamar Project.

George Salamis, President, CEO and Director of Integra commented:

"The first quarter of 2026 marked a period of strong operational progress at Florida Canyon, with record mining rates and the successful ramp-up of our Phase IIIB leach pad. While gold production in the quarter reflects temporary constraints, the deferred ounces are expected to be recovered over the balance of the year. Importantly, with these gold ounces expected to be recovered over the balance of the year, we maintained our full-year production guidance, underscoring our confidence in the operation and the improvements we have made to the Mine. In parallel, we significantly strengthened our balance sheet through a $61 M financing and continued to invest in both sustaining capital at Florida Canyon and the advancement of DeLamar. We believe these investments position Integra for a stronger second half of 2026 and reinforce our strategy of building a sustainable, multi-asset gold producer."

Florida Canyon: Demonstrating Strong Operational Momentum with Record Mining Rates

Florida Canyon produced 12,635 ounces of gold in the first quarter 2026, with approximately 3,000 ounces deferred due to temporarily reduced solution flow rates to a specific Phase II leach pad cell. The cell contains fine ore from the newly opened N2 pit, and a blending strategy has been developed to maintain nominal leach rates for this fine material. With this approach, together with the ramp up of the Phase IIIB leach pad, the Company expects to meet its annual gold production guidance of 70,000 to 75,000 ounces, with the majority of deferred first quarter ounces expected to be recovered through ongoing leaching over the remainder of 2026.

Mining activities at Florida Canyon during the first quarter 2026 increased significantly, achieving a record mining rate of 76,800 total tonnes per day and positioning the operation to deliver improved operational flexibility and production consistency in future quarters. This increase was driven by the addition of the six Caterpillar 785 haul trucks commissioned during the quarter, completing the expansion of the fleet since 2025 to include eight Caterpillar 785 haul trucks, one Caterpillar 992HL loader and one Hitachi EX3600 front shovel. With increased haulage capacity and an enhanced mining fleet, the operation is better equipped to manage the historical waste stripping inherited from prior operators.

The Company expects production to trend higher through the balance of 2026 as mining rates remain elevated and leach pad performance continues to normalize.

First Quarter 2026 Consolidated Financial Position: Strengthened Balance Sheet Supports Growth and Development Pipeline

The Company significantly strengthened its cash position in Q1 2026, primarily driven by a $61 M bought deal public offering in February 2026 and positive operating earnings from Florida Canyon. Proceeds from the offering are being used to fund pre-production expenditures at the DeLamar Project and funded the acquisition of a strategic land position near the DeLamar Project in February 2026. This strengthened financial position provides Integra with the flexibility to continue optimizing Florida Canyon while advancing DeLamar without compromising balance sheet discipline.

The first quarter of 2026 continued to mark a capital-intensive period across the Company's portfolio of assets with several key activities during the quarter. These investments reflect a deliberate focus on de-risking the portfolio and positioning the Company for sustainable production growth:

• Florida Canyon: Approximately $12 M was allocated to sustaining and non-sustaining capital including capitalized waste stripping and initial cash payments on new mining equipment.
• DeLamar and Nevada North: Approximately $5 M was allocated towards project expenses such as engineering and permitting work.
• DeLamar pre-production and de-risking activities: Approximately $16.5 M was allocated towards de-risking activities, including a $3.4 M initial deposit to Idaho Power, and $12.5 M spent to acquire a strategic land position near the DeLamar Project.

The financial information presented above is preliminary in nature and subject to completion of the Company's quarter-end financial reporting process. Final unaudited financial results may differ from these amounts and will be reported as part of the Company's quarter-end financial statements. Complete financial results for the first quarter 2026 will be reported and filed on Integra's profile on SEDAR+ at www.sedarplus.ca and EDGAR profile at www.sec.gov on Monday May 11, 2026.
