Florida Canyon First Phase Of Multi Year Growth Strategy

VANCOUVER - Integra Resources Corp. announced the initiation of a gold resource growth-focused drill program at the Florida Canyon Mine located in Nevada. The 2025 drill program marks the first phase of a multi-year growth strategy designed to expand mineral reserves and resources, extend mine life, and ultimately maximize the value of Florida Canyon.

The 2025 drill program will consist of ~10,000 meters (m) of reverse circulation ("RC") drilling focused on near-mine targets identified at Florida Canyon, designed to support oxide mineral reserve and resource growth and mine life extension. Drilling commenced in early May and is expected to conclude in the third quarter of 2025, with initial results expected to be released during the summer months of 2025. 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 early 2026.

The program is focused on testing near-mine targets at Florida Canyon in three key areas: 1) Opportunity 1: Near-surface oxide potential from historical dump material (~2,000m): Drilling will target large volumes of historical gold-mineralized backfill and low-grade waste material previously estimated to be below the mining cut-off grade in a significantly lower gold price environment. These areas demonstrate the greatest near-term opportunity to increase mineral resources and potentially extend mine life. 2) Opportunity 2: Expand in-situ resources between existing mine open pits (~5,000m): Drilling will target "saddle" and "ridge" areas located between active and historical pits. Many of these areas have been sparsely drilled historically and offer meaningful oxide growth potential directly adjacent to current and future mining phases. 3) Opportunity 3: Test lateral extensions and in-pit infill drilling (~3,000m): Drilling will target lateral extensions of existing pits as well as infill drilling within areas planned for further pit pushbacks. Potential has been identified to improve resource classification, optimize mine planning, and potentially increase short-term ore feed.

George Salamis, President, CEO and Director, said, "Following a strong start to 2025 with solid operational results from Florida Canyon gold production and a demonstrated ability to generate cash flow, we are pleased to launch a growth-focused drill program. We see this program as a critical step in unlocking the next phase of value at Florida Canyon. We have identified significant potential to not only optimize the mining operation, but also to increase the production scale and mine life of the asset, leading to material value creation for Integra's shareholders. We look forward to sharing our progress."
