Integra Resources Announces 2025 Growth Drilling Results at Florida Canyon Mine

Integra Resources Corp. has announced results from its 2025 growth drilling program at the Florida Canyon Mine in Nevada. The program consists of 16,000 meters of RC and sonic drilling, focused on near-surface oxide potential, expanding in-situ resources, and testing lateral extensions. The drill program is part of a multi-year growth strategy to expand mineral resources and reserves, extend mine life, and enhance the value of Florida Canyon.

VANCOUVER, BC, September 12, 2025 - Integra Resources Corp. (TSXV: ITR; NYSE American: ITRG) has released results from its 2025 growth drilling program at the Florida Canyon Mine in Nevada. The program, which consists of 16,000 meters of reverse circulation (RC) and sonic drilling, is part of a multi-year growth strategy aimed at expanding mineral resources and reserves, extending mine life, and enhancing the value of the Florida Canyon asset.

The drilling program is focused on three key areas: near-surface oxide potential, expanding in-situ resources between existing mine open pits, and testing lateral extensions. As of the announcement, approximately 13,000 meters of drilling have been completed.

Highlights of the 2025 Growth Drilling Program

1. Near-Surface Oxide Potential:
- Drilling is 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.
- The historical dump material presents an immediate opportunity to expand mineral resources and reserves with minimal mining cost.
- Initial drill results from the South Dump have demonstrated the potential for near-term oxide growth at Florida Canyon, with intercepts such as FCM25-0646: 0.21 g/t oxide Au over 73.2 meters.

2. Expanding In-Situ Resources Between Existing Mine Open Pits:
- Drilling is focused on "saddle" and "ridge" areas located between active and historical pits.
- Preliminary metallurgical tests suggest favorable heap leach characteristics for the material gathered from the drill program.
- Top intercepts from the Inter-Pit areas, such as FCM25-0592: 0.48 g/t Au over 76.2 meters, indicate significant upside gold potential.

3. Testing Lateral Extensions:
- The program is also testing lateral extensions and in-pit infill drilling to assess the extent of mineralization beyond the current mining boundaries.
- This phase aims to provide additional data to support a mineral resource and reserve update and a revised life-of-mine plan.

Implications for Integra Resources Corp.

The 2025 growth drilling program is expected to support a mineral resource and reserve update and a revised life-of-mine plan in the first half (H1) of 2026. George Salamis, President, CEO, and Director of Integra, commented, "We are pleased to see additional success from our 2025 near-mine oxide drilling campaign at Florida Canyon. Building on initial results released in August, we continue to see excellent gold-mineralized intercepts in both the historical dump and Inter-Pit areas, which confirm excellent grade continuity and continue to highlight the potential to grow mineral resources and extend mine life."

Conclusion

Integra Resources Corp.'s 2025 growth drilling program at the Florida Canyon Mine demonstrates significant potential for expanding mineral resources and reserves. The drilling results, along with metallurgical tests, indicate favorable characteristics for heap leaching and suggest that the near-surface oxide potential and in-situ resources could provide meaningful growth opportunities for the company.
