Integra Resources (ITR) Corporate presentation summary

Project transformation and mine plan updates

• Florida Canyon Mine expanded to an 8-year operational life with a 17% increase in annual gold production since 2024, following a $68 million acquisition and significant technical upgrades.

• Mineral reserves increased by 74% to 1.19 Moz, with average annual gold production rising to 82 koz and total gold sold projected at 685 koz over the life of mine.

• Updated mine plan leverages existing infrastructure, expands heap leach capacity, and incorporates modernized fleet and operational enhancements.

• Mine plan informed by two years of operational data, with improved geotechnical modeling, resource definition, and cost assumptions.

• Expansion and modernization efforts include increased slope angles, updated labor and cost models, and proactive maintenance strategies.

Financial performance and economics

• After-tax NPV (5%) is $601M (base case) and $723M (spot), with life-of-mine after-tax free cash flow estimated at $0.8B.

• Project economics are highly sensitive to gold price; a 10% increase in gold price boosts NPV and free cash flow by ~25%.

• Average annual after-tax free cash flow is $90M, supporting self-funding of mine expansion and pipeline projects.

• LOM average cash cost is $1,940/oz and AISC is $2,331/oz, with significant cost reductions after 2027 as capital investments are completed.

• Total sustaining and other capital costs over LOM are $379.7M, with major allocations to equipment, heap leach expansion, and reclamation.

Operational highlights and resource growth

• Heap leach gold operation with 8 years of mine life plus 2 years of residual leaching, using open pit and carbon-in-column recovery.

• 14.6 Mt of ore transferred to heap leach pads annually, with 7.1 Mt crushed and up to 9.3 Mt run-of-mine material.

• Gold recovery averages 56.7%, with heap leach expansion phases planned between 2026-2028 and 2030-2031.

• 50,000 m drilling program in 2026 targets resource growth, mine life extension, and development readiness across Florida Canyon, DeLamar, and Nevada North.

• Opportunities identified for further operational improvements, including increased crushing, haulage, and fleet modernization.
