INTEGRA REPORTS RECORD MINING AND ORE-STACKING RATES AT FLORIDA CANYON, 30% INCREASE IN SECOND QUARTER GOLD PRODUCTION

Integra Resources Corp. has provided an interim operational update for the second quarter ended June 30, 2026. Florida Canyon produced 16,379 ounces of gold during the quarter, a 30-per-cent increase from the first quarter of 2026. The increase in gold production was supported by record total material movement, including a 47-per-cent increase in ore mined and a 45-per-cent increase in ore placed on the heap leach pads quarter over quarter. With significantly more ore being placed on the heap leach pad in the second half of this year, the company expects gold production to increase in the third and fourth quarters, and is maintaining full-year gold production guidance of 70,000 to 75,000 ounces.

The company plans to release its second quarter 2026 financial results after market close on Tuesday, Aug. 11, 2026, followed by a conference call hosted by senior management on Wednesday, Aug. 12, 2026, at 10 a.m. Eastern Time/7 a.m. Pacific Time.

(All amounts are in U.S. dollars as at June 30, 2026, unless otherwise stated.)

Q2 2026 operational highlights:

• Key operating metric improvements quarter over quarter:
  • 30-per-cent increase in gold produced;
  • 16-per-cent increase in total tonnes mined;
  • 47-per-cent increase in ore mined;
  • 45-per-cent increase in ore placed on heap leach pads;
  • 21-per-cent increase in processed grade;
  • 38-per-cent decrease in strip ratio;
  • 8-per-cent decrease in waste mined.
• The company mined 4.4 million tonnes of ore and 3.6 million tonnes of waste at a strip ratio of 0.81 at the Florida Canyon mine. As a result, mining rates averaged 87,867 total tonnes per day, representing a record rate of total material movement at the mine.
• The Florida Canyon mine produced 16,379 ounces of gold and sold 15,794 ounces of gold during the second quarter, a 30-per-cent increase in gold production quarter over quarter. Gold production is expected to continue increasing through the second half of 2026, supported by the implementation of the N2 ore blending strategy, higher mining rates and increased ore stacking rates on the heap leach pads.
• Florida Canyon achieved record mining rates during the second quarter, with total tonnes mined increasing 16 per cent from the first quarter. The higher mining rates reflect the successful integration of new mining equipment into the fleet, positioning the operation for stronger gold production in the second half of 2026.
• The company released an updated feasibility study and life-of-mine plan for Florida Canyon, which highlighted a materially enhanced operation with an eight-year mine life, a 74-per-cent increase in proven and probable mineral reserve, a 17-per-cent increase in annual gold production, and $800-million in after-tax free cash flow.

George Salamis, president, chief executive officer and director of Integra, commented: "Florida Canyon continued to build operational momentum during the second quarter, with gold production increasing 30 per cent from the first quarter and both total material moved and ore placed on the heap leach pads reaching record levels. Approximately 4.2 million tonnes of ore were placed on the heap leach pads during the quarter, a 45-per-cent increase over the first quarter, creating a large inventory of recoverable gold ounces that is expected to support stronger gold production through the balance of this year.

"Beyond 2026, work is under way for the long-term transformation of Florida Canyon. As outlined in the June, 2026, technical report news release, beginning in 2027, the company expects higher annual gold production, lower operating costs and stronger cash flow from an eight-year mine life, creating a stable operation to support the continued advancement of the DeLamar and Nevada North projects."

Florida Canyon produced 16,379 ounces of gold in the second quarter 2026, with 29,014 ounces of gold produced year to date. The blending strategy developed in the first quarter of 2026 for N2 ore continues to leach as expected.

Mining activity at Florida Canyon continued to accelerate during the second quarter, with approximately eight million tonnes mined in total at an average mining rate of approximately 87,867 tpd. Record mining rates were achieved this quarter due to the integration of new mining equipment into the fleet over the past two quarters and shorter haul distances. Subsequent to quarter-end, ore stacking on the heap leach pads has exceeded expectations in July, positioning the operation for stronger gold production over the next two quarters. As a result of these mining rates, the company maintains annual gold production guidance in 2026 of 70,000 to 75,000 ounces, with increased gold production expected over the balance of the year.

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 second quarter 2026 will be reported and filed on Integra's profile on SEDAR+ and EDGAR on Tuesday, Aug. 11, 2026.
