Wildcat Drilling Program Provides Excellent Data For Future Programs

VANCOUVER - Integra Resources Corp. reported on the infill, geotechnical-metallurgical, and exploration drill program at the Wildcat Deposit located in Nevada. The 2024 drill program consisted of 10 holes, totaling ~1,940 meters ("m"). The drill program was designed to gather data from the heap-leachable material within the existing mineral resource, to test the potential blind high-grade breccia targets which are believed to be the feeder source of gold (Au) mineralization at Wildcat, and to demonstrate the continuity of mineralization.

The drill program significantly improved the team's geological, geotechnical, and metallurgical understanding of the Deposit. The infill and geo-metallurgical holes intersected mineralization and provided excellent data to support a future feasibility study. The drill program also helped to advance permitting efforts at Wildcat and provided valuable insight for future exploration programs. The exploration holes drilled, located ~200m to ~800m outside the main resource area, provide a solid indication of the presence of a potential feeder breccia pipe hidden below post-mineralization basalts. The encouraging geological interpretations from the exploration holes will guide further drilling campaigns aimed at defining the breccia pipe's geometry and potential high-grade zones.

Integra released a Preliminary Economic Assessment (PEA) for the Nevada North Project (comprised of the Wildcat and Mountain View Deposits) in June 2023 which demonstrated the potential for a low-cost, high margin, heap leach operation with robust economics.

A total of 3 infill and geo-metallurgical focused holes were drilled as part of the program. Drilling intercepted significant oxide mineralized material, confirming the excellent grade continuity at Wildcat. Drill intercepts within the 2023 PEA pit shell: WCCD-0017 returned an intercept of 0.52 grams per tonne ("g/t") oxide Au over 62.5m; WCCD-0018 returned an intercept of 0.38 g/t oxide Au over 64.6m; WCCD-0019 returned an intercept of 0.27 g/t oxide Au over 147.5m; Piezometers were installed in the drill holes to gather important data on the water table elevation at Wildcat. Demonstrating the absence of a pit lake is expected to support a simplified future permitting process; A total of 7 highly prospective exploration holes were drilled materially outside the 2023 PEA pit shell and primary mineral resource area: Breccia Pipe: 4 holes (totaling ~1,230m) were targeting the high-grade breccia pipe interpreted from geophysics and perceived to be located below post-mineralization basalts (step-out drilling from ~200m to ~800m north of Main Hill area). Although no significant high-grade interval was intercepted, WCCD-0016 returned 0.25 g/t non-oxide Au over 213.8m with pervasive alteration, hydrothermal brecciation, and visible Quartz veins (1-20 centimeters ("cm")). WCCD-0015 intersected lake sediments beneath post-mineralization basalts, potentially indicating that the hole is within the targeted diatreme. This was followed by an intercept of 0.22 g/t non-oxide Au over 12.2m and ended within post-mineralization felsic dykes. These dykes are believed to exploit pre-existing structures that have the potential to carry high-grade gold mineralization.
