to fund crucial reinvestment into the mine, while also supporting the Company's broader growth strategy. During the quarter, significant capital was deployed at

Florida Canyon in the areas of capitalized stripping, mining equipment enhancements, and leach pad expansion. Excellent production results from Florida Canyon

combined with the strong gold price environment have allowed Integra to significantly increase its quarter-over-quarter cash balance to

~$81 million

The Florida Canyon Mine ("Florida Canyon") produced 20,653 ounces of gold and sold 20,265 ounces of gold during the third quarter 2025, which is in-line with

the Company's expectations. Strong gold production continues to be supported by the recovery of gold ounces recently placed on the Phase IIIa heap leach pad

and by residual ounces recovered from Phases I and II leach pads. Gold production levels were further supported by increased solution flow rates through the

leach pads and the new carbon-in-column circuit commissioned late in 2024. The Company expects to meet its gold production guidance for 2025.

The increased strip ratio at Florida Canyon during the third quarter 2025 is a result of the Company's stated commitment of reinvestment through increased

capitalized waste stripping and ramping up new mining areas. Waste movement also increased during the third quarter 2025 due to a provisional adjustment of the

mine sequence to overcome dust suppression challenges caused by a temporary water shortage in the dry summer months. The temporary water shortage was

caused by a problematic historic water well, which has since been successfully replaced.

During the third quarter 2025, construction of the Phase IIIb heap leach pad at Florida Canyon continued with commissioning expected in the fourth quarter 2025.

Florida Canyon is also currently undergoing a revitalization of its mining fleet. As part of this effort, refurbishment is underway on haul trucks and loaders currently

on site and orders have been placed for several new key pieces of equipment, including eight new 150 ton Caterpillar haul trucks, a new Caterpillar loader, and a

new Hitachi mining shovel. The mining shovel has arrived on site and will be assembled, commissioned, and put into operation in the fourth quarter 2025. Delivery

of the new haul trucks will commence in the fourth quarter 2025 and continue into the first quarter 2026. The refurbished existing fleet and key new pieces of

equipment are expected to reduce reliance on expensive rental equipment, increase mining productivity, and lower mining cost per ton over the next several years

at Florida Canyon.
