Integra Identifies New Near-Mine Gold Growth Targets at Florida Canyon, including 1.30 g/t
Au over 62.5 m and 0.59 g/t Au over 167.6 m Inter-Pit and 0.48 g/t Au over 54.9 m in New
Madre Shear North Target
Vancouver, British Columbia - Integra Resources Corp. ("Integra" or the "Company") (TSXV: ITR; NYSE American: ITRG) is pleased to announce additional results from the growth and expansion drill program at the Company's producing Florida Canyon Mine ("Florida Canyon" or the "Mine") located in Nevada. The results announced today continue to demonstrate the potential to further expand the gold resource at Florida Canyon through newly identified targets, including the Madre Shear North Target, as well as underexplored areas between active and historical open pits.
Building on the 74% increase in Mineral Reserves and extended mine life outlined in the updated Florida Canyon life-of-mine plan and technical report1 (the "Technical Report"), Integra's ongoing drill program continues to target near-mine resource growth at Florida Canyon. The drill results announced today highlight multiple opportunities to potentially expand the gold resource at Florida Canyon within and immediately adjacent to the existing Mine footprint, including a newly accessible extension of the previously mined Madre Shear zone.
To date in 2026, the Company has completed 30,140 meters ("m") of reverse circulation ("RC") at Florida Canyon.
Highlights:
• Madre Shear North Target: The Madre Shear North Target represents the northern extension of the Madre Shear zone, a structure associated with gold mineralization. While the southern portion of the Madre Shear was mined by previous operators, its northern extension remained largely unexplored due to its location beneath the North Dump. With mineralized material from the North Dump added to the indicated mineral resource base in the Florida Canyon Technical Report, the potential for future mining activities in the area could provide increased access to the underlying Madre Shear North Target.
• Drill results from the Madre Shear North Target include:
• FCMR26-1284: 0.48 grams per tonne ("g/t") gold ("Au") over 54.9 m
• FCMR26-1279: 0.42 g/t Au over 9.1 m
• FCMR26-1282: 0.32 g/t Au over 6.1 m
• Resource expansion between existing open pits: Exploration drilling in the "saddles" and "ridges" ("Inter-Pit") areas located between active and historical open pits continue to demonstrate gold resource potential adjacent to operating and historic open pits.
• Drill results from the Inter-Pit area between the Central Open Pit and Radio Tower Open Pit (the "Central / Radio Tower Saddle") include:
• FCMR26-1250: 1.30 g/t Au over 62.5 m, including 9.37 g/t Au over 1.5 m and 14.74 g/t Au over 1.5 m
• FCMR26-1162: 0.59 g/t Au over 167.6 m
• FCMR26-1159: 0.83 g/t Au over 29.0 m, including 3.23 g/t Au over 4.6 m
• FCMR26-1155: 0.84 g/t Au over 35.1 m, including 4.04 g/t Au over 1.5 m and 4.08 g/t Au over 1.5 m
• North Dump: Mineralized material from the North Dump was drilled and modeled for inclusion in the updated mine plan outlined in the Technical Report filed in July 20261.
• Drill results from the North Dump include:
• FCMR26-0988: 0.38 g/t Au over 36.6 m
• FCMR26-0989: 0.40 g/t Au over 36.6 m
• FCMR26-1060: 0.39 g/t Au over 45.7 m, including 6.12 g/t Au over 1.5 m
Key Observations:
• The updated Technical Report at Florida Canyon highlighted a 74% increase in Mineral Reserves and the Company's continued commitment to mineral exploration at the Mine is demonstrating the potential for increased resource expansion in multiple areas of Florida Canyon.
• The results announced today are from exploration targets within the footprint of the Mine and have the potential to be included in future mine plans.
• The Company is also planning to test exploration targets outside the Mine footprint, including 7,000 m of drilling at the Standard Mine area located 8 kilometers ("km") south of Florida Canyon.

George Salamis, President and CEO of Integra Resources, commented: "The drill results reported today include some of the best gold intercepts drilled since Integra acquired Florida Canyon. The continued success in exploring the Mine has reinforced our view that the updated Technical Report was not the culmination of the Florida Canyon growth story; rather, it was the start of potential sustained resource growth that can be accomplished through disciplined exploration. Since the drill results announced today occur within or immediately adjacent to the existing mine operations and infrastructure, this gold mineralized material has the potential to positively impact and expand near-term mine plans.
We are particularly excited about the gold potential of the Madre Shear North Target. The Madre Shear is a structure known to host gold mineralization at Florida Canyon; however, due to the location of the North Dump, only the southern extension of the Madre Shear zone was mined previously. With portions of the North Dump expected to be mined in future years as part of the current mine plan, the Company expects to gain increased access to this area while continuing to evaluate opportunities to further drill and investigate its potential for inclusion in future mine plans.
The on-going, successful drill campaigns initiated since acquiring Florida Canyon, along with the 74% increase in Mineral Reserves reported in the updated Technical Report, continue to confirm our 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."
Drilling Overview
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.

The Madre Shear North Target
The Madre Shear zone is a geologic structure that is orthogonal to the highly prospective Range Front Fault, an important structural control associated with gold mineralization at Florida Canyon. The Range Front Fault extends through both the Central Pit and North Dump. Approximately 2,000 m of drilling was completed at the Madre Shear North target in phase one on a 91 m by 47 m grid. An additional 2,000 m of drilling is planned to further evaluate the scale, continuity and resource potential of this new target.
Select gold intercepts from drilling at the Madre Shear North:
- FCMR26-1284: 0.48 g/t Au over 54.9 m
- FCMR26-1279: 0.42 g/t Au over 9.1 m
- FCMR26-1282: 0.32 g/t Au over 6.1 m
Key observations
- The Madre Shear zone is a structure associated with gold mineralization at the Mine with the southern extension of this structure mined by previous operators. Drill results announced today returned broad zones of gold mineralization across multiple holes, demonstrating the potential for a meaningful near-mine resource.
- Mineralization intersected at the Madre Shear North Target is near-surface and will become increasingly accessible as material from the North Dump is mined in the future. Located immediately adjacent to existing mining infrastructure, the target could benefit from shorter haulage distances and lower capital requirements, potentially enhancing its economics relative to more distal mineralization.
- Mining of the southern portion of the Madre Shear zone was completed by previous operators, suggesting the material from the Madre Shear North target is amenable to heap leach processing, subject to ongoing metallurgical testing.

The Central / Radio Tower Saddle Target:
Drilling focused on the Central / Radio Tower Saddle Target has identified a zone of consistent mineralization above and adjacent to in-situ gold resources. The drill results announced today, along with those previously announced (please see news release dated August 5, 2025), continue to demonstrate strong resource expansion potential in this area. Additional drilling is planned at the Central / Radio Tower Saddle Target to further test areas with limited previous drilling. Results announced to date show broad, near surface intervals of gold mineralization consistent with existing gold grades at the Mine.
Select gold intercepts from drilling in the Central / Radio Tower Saddle Target:
- FCMR26-1250: 1.30 g/t Au over 62.5 m, including 9.37 g/t Au over 1.5 m and 14.74 g/t Au over 1.5 m
- FCMR26-1159: 0.83 g/t Au over 29.0 m, including 3.23 g/t Au over 4.6 m
- FCMR26-1152: 0.72 g/t Au over 22.9 m; and 7.52 g/t Au over 6.1 m including 28.80 g/t Au over 1.5 m
- FCMR26-1155: 0.84 g/t Au over 35.1 m, including 4.04 g/t Au over 1.5 m and 4.08 g/t Au over 1.5 m
- FCMR26-1147: 0.48 g/t Au over 9.1 m; 0.37 g/t Au over 10.7 m; and 1.60 g/t Au over 10.7 m, including 5.34 g/t Au over 1.5 m
- FCMR26-1162: 0.59 g/t Au over 167.6 m
Key observations
- Converting Inter-Pit areas like the Central / Radio Tower Saddle Target into potential gold resource can provide additional opportunities to expand the known resource at Florida Canyon and provide future mining flexibility due to their location next to existing open pits and infrastructure.
- Multiple drill holes are planned north of the results announced today to confirm continuity in the Central / Radio Tower Saddle Target area and provide data for inclusion of this material in future mine plans.
- Strong thickness-grade relationships exist in the Central / Radio Tower Saddle Target with mineralization occurring at surface, supporting low-strip mining at Florida Canyon.

North Dump Drill Results
Gold mineralized material from the North Dump was modeled and included in the mine plan outlined in the updated Technical Report. Since this material was previously mined, the associated mining cost has already been incurred and its location near processing infrastructure reduces hauling distance and operating expenses related to this material. The drill results announced today demonstrate the strong grade and continuity of material in the North Dump, supporting the Company's decision to include it in the current mine plan.
Select intercepts from drilling in the North Dump include:
- FCMR26-0989: 0.40 g/t Au over 36.6 m
- FCMR26-0988: 0.38 g/t Au over 36.6 m
- FCMR26-1060: 0.39 g/t Au over 45.7 m, including 6.12 g/t Au over 1.5 m
- FCMR26-0979: 0.35 g/t Au over 30.5 m
- FCMR26-1022: 0.34 g/t Au over 54.9 m
- FCMR26-0983: 0.30 g/t Au over 38.1 m
- FCMR26-1045: 0.41 g/t Au over 36.6 m; 0.27 g/t Au over 27.4 m; and 0.26 g/t Au over 12.2 m
Key observations
- The overall cost of including North Dump material in the mine plan is lower than in-situ resource given its location and the fact that it has been previously mined as waste.
- Drilling has shown strong grade continuity within the North Dump that is consistent or above current mining grades.
Strategic Implications
- Near-mine resource growth: Drilling continues to identify broad zones of gold mineralization within and immediately adjacent to the existing Mine footprint, highlighting multiple opportunities to add resources and potentially extend mine life.
- New exploration target: Future mining of the North Dump could provide increased access to the underlying Madre Shear North Target, creating a new near-mine exploration opportunity.
- Inter-Pit resource potential: Continued drill success in Inter-Pit areas like the Central / Radio Tower Saddle Target demonstrates the potential to increase the Mine resource base and contribute to future production.

Sampling and QA/QC Procedure
Reverse circulation samples were collected at 5-foot intervals directly at the drill rig using pre-labeled bags. Samples were submitted to American Assay Laboratories ("AAL") in Reno, Nevada, an ISO/IEC 17025 accredited laboratory. AAL is independent of Integra. Sample preparation involved drying, jaw crushing to >70% passing 2 mm (10 mesh) and pulverizing a 300 g split to >85% passing 75 microns.
Gold analysis was performed on a 30-gram pulp using fire assay with ICP-AES finish. Samples returning >10 ppm Au were re-assayed using a gravimetric finish. Additionally, samples with Au >0.156 ppm underwent cyanide-soluble (0.3% NaCN/0.3%NaOH using a sample to solution ratio of 1:2 or 10g/20mL) analysis and preg-robbing (0.3% NaCN/0.3%NaOH + 1.71ppm/mL Au spike using 1:2 ratio calculates to 3.42ppm in the 10g/20mL) tests to assess metallurgical characteristics. Quality control protocols included the routine insertion of blank samples, certified reference materials (standards), and field and pulp duplicates. Blank material and standards were purchased from Moment Exploration Geochemistry. AAL also inserted internal control samples and duplicates within each batch.
