Integra Resources Discovers New Gold Targets at Florida Canyon Mine

VANCOUVER, BC, Sept. 23, 2026 /CourierPR/ -- Integra Resources Corp. has announced the discovery of new gold growth targets at its Florida Canyon Mine in Nevada. The company's ongoing exploration program has identified multiple opportunities to expand the gold resource within and adjacent to the existing mine footprint, including the Madre Shear North Target and areas between active and historical open pits.

The Madre Shear North Target, a northern extension of the Madre Shear zone, has shown promising results. Drill results from this target include: - FCMR26-1284: 0.48 grams per tonne (g/t) gold over 54.9 meters - FCMR26-1279: 0.42 g/t gold over 9.1 meters - FCMR26-1282: 0.32 g/t gold over 6.1 meters

These findings are significant as they represent the first exploration of the northern extension of the Madre Shear zone, which was previously mined only in its southern portion. With the North Dump expected to be mined in future years, access to the underlying Madre Shear North Target is anticipated to improve, potentially enhancing the economics of the material.

Additionally, exploration in the "saddles" and "ridges" areas between the Central Open Pit and Radio Tower Open Pit has continued to demonstrate gold resource potential. Key drill results include: - FCMR26-1250: 1.30 g/t gold over 62.5 meters, including 9.37 g/t gold over 1.5 meters and 14.74 g/t gold over 1.5 meters - FCMR26-1162: 0.59 g/t gold over 167.6 meters - FCMR26-1159: 0.83 g/t gold over 29.0 meters, including 3.23 g/t gold over 4.6 meters - FCMR26-1155: 0.84 g/t gold over 35.1 meters, including 4.04 g/t gold over 1.5 meters and 4.08 g/t gold over 1.5 meters

The North Dump, which was drilled and modeled for inclusion in the updated mine plan, has also shown strong grade and continuity of gold mineralization. Drill results from the North Dump include: - FCMR26-0989: 0.40 g/t gold over 36.6 meters - FCMR26-0988: 0.38 g/t gold over 36.6 meters - FCMR26-1060: 0.39 g/t gold over 45.7 meters, including 6.12 g/t gold over 1.5 meters

The company is planning to test exploration targets outside the Mine footprint, including 7,000 meters of drilling at the Standard Mine area located 8 kilometers south of Florida Canyon. The ongoing, successful drill campaigns initiated since acquiring Florida Canyon continue to confirm the company's belief that there is meaningful potential at Florida Canyon to further grow the resource base and extend mine life, increasing the long-term value of the operation.

The growth and expansion drill program at Florida Canyon is focused on delineating near-surface oxide gold mineralization within and adjacent to existing mining areas that can quickly contribute and extend the mine life of Florida Canyon. The program is designed to support future mineral resource and reserve updates and inform life-of-mine planning.
