INTEGRA ANNOUNCES THIRD QUARTER GOLD PRODUCTION OF 17,652 OUNCES, DEMONSTRATING CONTINUED GROWTH IN MINING AND GOLD PRODUCTION AT FLORIDA CANYON

Integra Resources Corp. has provided an interim operational update for the third quarter ended Sept. 30, 2026. The Florida Canyon mine produced 17,652 ounces of gold during the quarter, an 8-per-cent increase from the second quarter of 2026 and a 40-per-cent increase from the first quarter of 2026. Ore mined and placed on the heap-leach pads at Florida Canyon has continued to increase throughout the year with a 21-per-cent increase in ore mined and a 25-per-cent increase in ore placed on the heap-leach pads quarter over quarter. Mining and ore stacking rates continue to improve at Florida Canyon, and the company continues to target its previously announced full-year gold production guidance of 70,000 to 75,000 ounces.

The company plans to release its third quarter 2026 financial results after market close on Wednesday, Nov. 11, 2026, followed by a conference call hosted by senior management on Thursday, Nov. 12, 2026, at 10 a.m. EST/8 a.m. PCT/7 a.m. PST.

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

Q3 2026 operational highlights:

• The company mined 5.3 million tonnes of ore and 3.6 million tonnes of waste at a strip ratio of 0.68 at Florida Canyon. As a result, mining rates averaged 97,428 total tonnes per day, representing another record quarter of tonnes moved at the mine.
• Florida Canyon produced 17,652 ounces of gold and sold 16,760 ounces of gold during the third quarter, an 8-per-cent increase in gold production quarter over quarter.
• The strip ratio at Florida Canyon has decreased 16 per cent from the second quarter of 2026 and 48 per cent from the first quarter of 2026.
• Processed gold grade at the mine has increased 9 per cent from the second quarter of 2026 and 32 per cent from the first quarter of 2026.

George Salamis, president, chief executive officer and director of Integra, commented: "Production in Q3 2026 rose 8 per cent over the second quarter and 40 per cent over the first quarter of 2026. Ore mined and ore placed on the heap-leach pads have continued to increase year to date, and processed grades have improved steadily throughout the year. Mining rates are expected to remain elevated this quarter as we focus on annual production guidance.

"Our goal is to make Florida Canyon a more predictable, cost-effective operation through targeted investments in stripping, leach-pad expansion, mobile fleet and other infrastructure improvements. The Central pit prestripping campaign continues to be a key priority for the site team, with work progressing toward improved access to higher-grade ore in 2027. The Central pit is expected to deliver higher-grade ore to support production in the coming years. Strategic investments at Florida Canyon will continue into 2027 at an expected lower rate.

"With $119-million of cash on hand, we are well positioned to fund ongoing investment at Florida Canyon and growth-focused exploration while advancing our project pipeline. This includes progressing the DeLamar project through permitting toward a final investment decision, expected in the second half of 2027, and completing economic studies and prepermitting work at the Nevada North project."

Florida Canyon produced 17,652 ounces of gold in the third quarter of 2026, with 46,666 ounces of gold produced year to date. Mining activity at Florida Canyon increased 12 per cent over the second quarter of 2026 with approximately 9.0 million total tonnes mined at an average mining rate of approximately 97,428 tonnes per day.

The record tonnes mined this year have increased the ounces stacked on the heap-leach pads, driving quarter-over-quarter production growth. Increased run-of-mine ore placement contributed to a lower blended gold recovery rate, reflecting the lower expected recovery of run-of-mine ore relative to crushed ore. The ore stacking and blending strategy used since Q1 is being monitored closely and refined at these higher mining rates.

The financial information presented above is preliminary in nature and subject to completion of the company's quarterly financial reporting process. Complete financial results for the third quarter of 2026 will be reported and filed on Integra's profile on SEDAR+ and EDGAR on Tuesday, Nov. 10, 2026.
