Integra Intersects 0.74 G/T AuEq Over 38 M and 0.50 G/T AuEq Over 79 at DeLamar, 0.67 G/T AuEq Over 58 M at Florida Mountain in Stockpile Drill Program, Expanding The Potential Heap Leach Oxide Resource at DeLamar

VANCOUVER, British Columbia, April 19, 2023 (GLOBE NEWSWIRE) — Integra Resources Corp. (“Integra” or the “Company”) (TSX-V: ITR; NYSE American: ITRG) is pleased to announce twenty additional drill holes from the expanded stockpile drill program underway at the DeLamar Project (“DeLamar” or the “Project”) located in southwestern Idaho. The drill results announced today are from the North DeLamar backfill, Sommercamp backfill, Stockpile 1, and Stockpile 2 located at the DeLamar Deposit and the Jacobs Gulch stockpile and Tip Top backfill at Florida Mountain. In total, the Company has drilled 11,300 m in 289 drill holes during the stockpile drill program and expects to complete the drill program this month. The consistent gold equivalent grade and drill intercept widths encountered throughout the stockpile drill program provides additional conviction that this material could significantly increase the oxide and mixed heap leach resource at DeLamar and Florida Mountain. Additional oxide-and-mixed material at the Project has the potential to materially increase the heap leach mine life in future phases of the Project and further enhance the robust economics presented in the Company’s 2022 Pre-feasibility Study (“PFS”).
