INTEGRA ANNOUNCES CONSISTENT SECOND QUARTER 2025 GOLD PRODUCTION RESULTS FROM FLORIDA CANYON MINE AND INCREASED CASH BALANCE TO US$63 MILLION

Integra Resources Corp. has provided an interim operational update for the second quarter ended June 30, 2025. The company plans to release its second quarter 2025 financial results after market close on Wednesday, Aug. 13, 2025, followed by a conference call hosted by senior management on Thursday, Aug. 14, 2025, at 11 a.m. Eastern Time/8 a.m. Pacific Time.

(All amounts are in U.S. dollars as at June 30, 2025, unless otherwise stated.)

George Salamis, president, chief executive officer and a director of Integra, commented: "Florida Canyon continues to deliver on our expectations, generating meaningful cash flow to fund significant reinvestment into the mine, while also supporting the company's broader growth strategy. As described in our 2025 guidance, between sustaining and growth capital, the company plans to invest over [approximately] $55-million into Florida Canyon this year -- capital that not only supports near-term improvements but also positions the mine for long-term growth and profitability. Over all, we are very pleased with the consistent operational delivery from Florida Canyon and the momentum it is helping us build across the business."

The Florida Canyon mine produced 18,086 ounces of gold and sold 18,194 ounces of gold during the second quarter of 2025, in line with the company's expectations. Consistent gold production was supported by the recovery of gold ounces placed on the phase IIIa heap-leach pad in the first and second quarters of 2025 as well as residual ounces leached from phase I and phase II heap-leach pads. The increased strip ratio during the second quarter of 2025 is a result of increased capitalized waste stripping as part of the company's reinvestment strategy at Florida Canyon, which was outlined in the company's 2025 guidance. During the second quarter of 2025, construction of the phase IIIb heap-leach pad at Florida Canyon was initiated, with commissioning expected in late 2025.

Complete financial results for the second quarter of 2025 will be reported and filed on Integra's profile on SEDAR+ and EDGAR on Wednesday, Aug. 13, 2025.
