Integra Resources Corp. ("Integra" or the "Company") (TSXV:ITR) (NYSE:ITRG) is pleased to announce results from the 2025 growth drilling program at the Company's primary operating asset, the Florida Canyon Mine ("Florida Canyon") located in Nevada. The drill program marks the first phase of a multi-year growth strategy designed to expand mineral resources and reserves, extend mine life, and enhance the value of Florida Canyon.

The 2025 growth drilling program consists of 16,000 meters ("m") of reverse circulation ("RC") and sonic drilling and is focused on three key areas: (1) Near-surface oxide potential from historical low-grade gold-mineralized waste material that was uneconomic at lower gold prices; (2) Expanding in-situ resources between existing mine open pits; and (3) Testing lateral extensions and in-pit infill drilling. As of the date of this news release ~13,000 m of drilling has been completed.

Highlights:

• Opportunity 1: Near-surface oxide potential from historical dump material: Drilling targeting large volumes of historical, gold-mineralized, low-grade waste material that was below the mining cut-off in a significantly lower gold-price environment. These areas demonstrate a significant near-term opportunity to increase mineral resources and potentially extend mine life at Florida Canyon.
  • Initial results from the South Mine Dump ("South Dump") confirmed near-surface intervals of oxide gold mineralization with consistent gold grades. Top intercepts include (see detailed table below):
    • FCM25-0646: 0.21 grams per tonne ("g/t") oxide gold ("Au") over 73.2 m
    • FCM25-0652: 0.20 g/t oxide Au over 68.6 m
    • FCM25-0647: 0.20 g/t oxide Au over 53.3 m
    • ~70% of drill intercepts exceed the current mine cut-off grade of 0.11 g/t Au
  • Preliminary volume and grade estimates for the North Mine Dump ("North Dump") and South Dump areas (see below for further detail and estimation assumptions):
    • North Dump: Estimated potential volume of ~19 - 32 million tonnes with a grade range of ~0.11 - 0.25 g/t oxide Au
    • South Dump: Estimated potential volume of ~15 - 24 million tonnes with a grade range of ~0.11 - 0.25 g/t oxide Au
    • Combined North and South Dump: Estimated potential volume of ~34 - 56 million tonnes with a grade range of ~0.11 - 0.25 g/t oxide Au
• Opportunity 2: Expand in-situ resources between existing mine open pits: Drilling targeting "saddle" and "ridge" ("Inter-Pit") areas located between active and historical pits. Many of these areas have been sparsely drilled historically and offer meaningful growth potential directly adjacent to current and future mining phases.
  • Continued results from Inter-Pit areas confirmed broad intervals of gold mineralization with consistent gold grades and heap leach potential. Top intercepts include (see detailed table below):
    • FCM25-0592: 0.48 g/t Au over 76.2 m, incl. 8.03 g/t Au over 1.5 m and 3.13 g/t Au over 1.5 m (Central / Radio Tower Saddle)
    • FCM25-0625: 0.81 g/t Au over 76.2 m, incl. 14.87 g/t Au over 1.5 m (Radio Tower Extension)
    • FCM25-0609: 0.28 g/t Au over 100.6 m (Jasperoid Hill Pit)
    • ~16% of drill intercepts within the Radio Tower Pit exceed the current Radio Tower cut-off grade of 0.14 g/t Au
    • ~29% of drill intercepts within the remaining Inter-Pit areas exceed the current mine cut-off grade of 0.11 g/t Au
• Metallurgical bottle roll leach tests are underway on material gathered from the drill program to assess potential gold recoveries and other ore characteristics; preliminary indications suggest favorable heap leach characteristics.
• The 2025 drill program at Florida Canyon is expected to support a mineral resource and reserve update and a revised life-of-mine plan in the first half ("H1") of 2026.
