Fourth Quarter & Full Year 2024 Financial and Operating Summary

Total crushed and run-of-mine ("ROM") material to the pad from November 8 to December 31, 2024 was 1.6 million tonnes with a strip ratio of 0.45. The average grade of ore processed during the period was 0.25 grams per tonne ("g/t") gold. Mined and placed material for the fourth quarter exceeded expectations as a result of excellent crusher performance and delivery of more ROM material to the leach pad than planned. Strong production performance in 2024 at Florida Canyon was also supported by the construction and commissioning of the new Phase III-A of the South Heap Leach Pad and enhancements to solution processing systems.

Gold produced from November 8 to December 31, 2024 was 10,984 ounces. Production during the fourth quarter was particularly strong as a result of the newly constructed, carbon-in-column ("CIC") circuit which came online during the quarter. Gold sold from November 8 to December 31, 2024 was 11,382 ounces at an average realized gold price of $2,643 per ounce, for total revenue of $30.4 million. Cash costs and AISC during the period totaled $1,884 and $2,103 per ounce of gold sold, respectively.  For the fiscal year 2024, total sustaining capital at Florida Canyon was $41.3 million, with approximately $30 million towards the heap leach pad expansion and CIC, and approximately $8 million in deferred stripping.

Several optimization studies are underway at Florida Canyon, some of which are expected to be completed in the first half of 2025, while others will continue throughout 2025 and beyond. One of the optimization studies is the review of the mobile equipment fleet, which will require planned component replacement in 2025 and 2026. Other optimization studies are evaluating several components of the mining operation including metallurgy, mine sequencing, and pit slope/geotechnical studies which are aimed at reducing future strip ratio. Lastly, an expanded exploration program at Florida Canyon is expected to be initiated in Q2 2025, which will be focused on drilling extensions to existing mine deposits, with the goal of adding oxide material to the mine plan and potentially extending mine life.

2025 sustaining capital expenditures will include the expansion of the South Heap Leach Pad Phase III-B, which is expected to amount to ~$12 million.

Development Projects – 2024 Expenditures & Highlights

Exploration and project expenditures at DeLamar, Nevada North, and other exploration properties was $14.2 million for the fiscal year 2024. It included $1.0 million in exploration drilling at the Wildcat Deposit (Nevada North) and $8.2 million in engineering and permitting work at DeLamar.

The DeLamar Project 

Engineering

The feasibility study at DeLamar continued to make progress in the fourth quarter of 2024, with final metallurgical and engineering test work completed. Key achievements include:

• Optimization of the heap leach pad footprint, reducing expected capital expenditures and improving infrastructure efficiency.
• Finalization of the gold and silver recovery model, confirming that tertiary crushing is unnecessary based on test work conducted at Forte Laboratory in Denver. Materials from the DeLamar pit with clays requiring agglomeration will be screened at 1" with oversize conveyed to the pad and undersize conveyed to the agglomeration circuit. Materials from Florida Mountain will likely not require agglomeration due to low clay content.
• Advancements in mine sequencing and economic modeling in collaboration with Whittle Consulting.
• The elimination of the need for tertiary crushing opened the opportunity to revert to line power supplied by Idaho Power. The demand below 6MW will require only a transformer upgrade at the DeLamar site substation and a refurbishment of 8 miles of transmission line in the urban Caldwell area. Idaho Power is preparing a Construction Study to establish upgrade costs attributable to Integra.
• No gold/silver refinery is expected to be required at DeLamar. Precipitate from the Merrill Crowe process will be securely shipped to Florida Canyon for final refining. This is expected to positively affect the air quality permitting and reduce capital expenditures and operating expenses.

Permitting

Throughout 2024, significant progress was made on the DeLamar Mine Plan of Operations ("MPO"), including key regulatory milestones, environmental surveys, and coordination with federal and state agencies. The Company focused on refining its operational and permitting strategy, addressing agency concerns, and advancing critical environmental and engineering studies. Key activities include:

• The preliminary MPO was submitted to the U.S Bureau of Land Management ("BLM") in late 2023. In June 2024, the BLM confirmed that the MPO has met the content requirement of the United States Code of Federal Regulations Title 43 Subpart 3809.
• A strategy was developed to incorporate feasibility study design changes into the MPO, with considerations including a direct revision to the MPO, evaluation as alternatives in the Environmental Impact Statement ("EIS"), or a combination of both.
• The Company engaged in ongoing discussions with the BLM, and the BLM continued to review and accept environmental baseline reports for the project, with ongoing responses to agency comments and questions.
• Coordination efforts between agencies, including the Idaho Department of Lands and the Idaho Department of Environmental Quality, were initiated to develop a project-specific Memorandum of Understanding ("MOU").
• Federal regulatory agencies in Washington, DC, were visited in 2024 with the goal of establishing contacts and relationships to support future permitting.

The Nevada North Project 

Drilling

A 10-hole, 1,940-meter drill program was successfully completed at the Wildcat Deposit in Nevada in Q2 and Q3 2024. The objectives were to refine geological, geotechnical, and metallurgical data while testing high-priority exploration targets at the same time. Core samples were sent to both geotechnical and metallurgical laboratories for further analysis. These results will strategically inform the next phase of studies, further refining project development and supporting future mine permitting efforts.

Integra issued an exploration news release dated December 12, 2024 with the following key findings:

• Infill drilling within the 2023 Preliminary Economic Assessment ("PEA") pit shell confirmed excellent oxide gold continuity, with intercepts including:
  • WCCD-0017: 0.52 g/t Au over 62.5m
  • WCCD-0018: 0.38 g/t Au over 64.6m
  • WCCD-0019: 0.27 g/t Au over 147.5m
  • Piezometer installations in key drill holes confirmed that the pit is expected to remain dry, which has the potential to simplify permitting and future operations.
• The exploration drilling performed well outside of the PEA pit shell and under cover rock which blinded the mineralized target, confirmed intense alteration and brecciation, reinforcing the potential for a high-grade breccia feeder system to occur. Hole WCCD-0016 intercepted 213.8m of 0.25 g/t non-oxide Au, with strong hydrothermal brecciation and quartz veining, while WCCD-0015 intersected sediments beneath post-mineralization basalts, suggesting proximity to a targeted diatreme and intersected 12.2m of 0.22 g/t non-oxide Au. For detailed drill results and sampling and QA/QC procedures, please see the Company's news release dated December 12, 2024 available under the Company's SEDAR+ profile at www.sedarplus.ca and the Company's EDGAR profile at www.sec.gov.

Permitting

The Environmental Assessment for the Wildcat Exploration Plan of Operations was completed in 2024. The subsequent Finding of No Significant Impact and the Decision Record is still pending but are anticipated to be received in mid 2025. The first tranche of Sage Grouse Conservation Credits were acquired for the Wildcat Exploration Project in December 2024, achieving compliance with the Nevada Sagebrush Ecosystem Program.
