INTEGRA ANNOUNCES RESULTS FROM NEAR-MINE OXIDE GOLD DRILLING AT FLORIDA CANYON; INITIAL DUMP VOLUME AND GRADE ESTIMATES UNDERSCORE NEAR-TERM GROWTH POTENTIAL

Executive Summary

• Integra reported initial results from its 2025 growth drilling program at Florida Canyon, highlighting significant near‑surface oxide gold intercepts in historic dump material and inter‑pit zones.
• Preliminary volume‑grade estimates suggest the North & South Dumps could contain 34–56 Mt of ore grading 0.11–0.25 g/t Au, representing a sizable near‑term resource growth opportunity.
• High‑grade intercepts were also observed in inter‑pit targets (e.g., 0.81 g/t Au over 76.2 m with a 14.87 g/t Au sub‑interval), supporting potential pit expansion and extended mine life; an updated mineral resource, reserve estimate and LOM plan are slated for H1 2026.

Key Details

• Drilling Program Scope: ~16,000 m planned; ~13,000 m completed to date (RC & sonic).
• Dump Material Results (South Dump):
• FCM25‑0646 – 0.21 g/t Au over 73.2 m
• FCM25‑0652 – 0.20 g/t Au over 68.6 m
• FCM25‑0647 – 0.20 g/t Au over 53.3 m
• ~70% of dump intercepts exceed the mine cut‑off (0.11 g/t Au).
• Preliminary Dump Volume & Grade Estimates:
• North Dump – 19–32 Mt @ 0.11–0.25 g/t Au
• South Dump – 15–24 Mt @ 0.11–0.25 g/t Au
• Combined – 34–56 Mt @ 0.11–0.25 g/t Au
• Inter‑Pit (Saddle/Ridge) Results:
• FCM25‑0592 – 0.48 g/t Au over 76.2 m (incl. 8.03 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 Radio Tower intercepts exceed 0.14 g/t cut‑off; ~29% of other Inter‑Pit intercepts exceed 0.11 g/t cut‑off.
• Metallurgical Testing: Bottle‑roll leach tests underway; early indications show favorable heap‑leach characteristics for dump material.
• Future Outlook: Results will feed an updated NI 43‑101 mineral resource and reserve model and a revised life‑of‑mine plan expected in the first half of 2026.
