Integra Resources Announce Additional Results From its Drill Program At The Florida Canyon Mine In Nevada; Data Continue To Demonstrate Potential To Further Expand The Established Gold Resource
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
- Drill results from the Madre Shear North Target include:
- 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
- Drill results from the Inter-Pit area between the Central Open Pit and Radio Tower Open Pit (the "Central / Radio Tower Saddle") include:
- 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
- Drill results from the North Dump include:
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.
