INTEGRA ANNOUNCES STRONG FIRST QUARTER 2025 GOLD PRODUCTION RESULTS FROM FLORIDA CANYON MINE AND INCREASED CASH BALANCE TO US$61 MILLION

Integra Resources Corp. has provided an interim operational update for the first quarter ended March 31, 2025. The company plans to release its first quarter 2025 financial results after market close on Wednesday, May 14, 2025, followed by a conference call hosted by senior management on Thursday, May 15, 2025, at 11 a.m. ET (8 a.m. PT). All amounts are in United States dollars as at March 31, 2025, unless otherwise stated.

First quarter 2025 Florida Canyon mine operational update

The Florida Canyon mine produced 19,323 ounces of gold and sold 19,540 ounces of gold during the first quarter of 2025. Gold production exceeded expectations, partly due to the recovery and processing of approximately 2,000 ounces of previously unrecovered gold confined within an electrowinning tank as part of a one-time efficiency improvement project. Strong gold production was further supported by the continued ramp-up of solution flow rates through the heap-leach pads and a new carbon-in-column circuit commissioned in late 2024.

Full financial results for the first quarter 2025 will be reported and filed under Integra's SEDAR+ profile and EDGAR profile Wednesday, May 14, 2025.
