Integra Resources Corp. announced drill results from 20 additional drill holes, representing 1,009 meters, from the stockpile drill program at the DeLamar Project located in southwestern Idaho. The stockpile drill program at DeLamar was designed to test a large portion of the estimated 60 million tonnes of mineralized material that was stockpiled and/or used as backfill at the Project.

The Company believes that additional oxide-and-mixed material from the stockpiles and backfill at DeLamar has the potential to significantly increase the heap leach mine life of the Project in future phases and further bolster the robust economics presented in the Company’s 2022 Pre-feasibility Study. The latest drilling highlights from DeLamar (North DeLamar, Sommercamp, Stockpile 1 and 2) include: NDM-23-047: 0.30 grams per tonne (“g/t”) gold (“Au”) and 17.38 g/t silver (“Ag”) (0.52 g/t gold equivalent (“AuEq”)) over 111.25 m NDM-23-045: 0.29 g/t Au and 18.54 g/t Ag (0.53 g/t AuEq) over 74.68 m NDM-23-031: 0.25 g/t Au and 16.45 g/t Ag (0.46 g/t AuEq) over 85.34 m WD1-23-168: 0.65 g/t Au and 20.91 g/t Ag (0.92 g/t AuEq) over 39.62 m, including 12.51 g/t Au and 31.04 g/t Ag (12.91 g/t AuEq) over 1.52 m The latest drilling highlights from Florida Mountain (Jacobs Gulch and Tip Top) include: JG-23-046: 0.35 g/t Au and 7.83 g/t Ag (0.45 g/t AuEq) over 35.05 m JG-23-158: 0.42 g/t Au and 7.30 g/t Ag (0.51 g/t AuEq) over 39.62 m JG-23-097: 0.35 g/t Au and 7.34 g/t Ag (0.45 g/t AuEq) over 35.05 m The drill results announced continue to demonstrate excellent gold equivalent grade and drill intercept widths with strong continuity throughout the stockpile and backfill mineralized material. The Company has released 155 drill holes of the 321 drill holes completed during the 12,588 m stockpile drill program which was completed in April 2023.

Following the successful release of the updated mineral resource estimate and Preliminary Economic Assessment (“PEA”) for the Wildcat & Mountain View Projects, the Company is currently focused on delivering an updated mineral resource estimate for DeLamar in Third Quarter 2023, including the stockpile drilling, as well as the submission of the Mine Plan of Operations at DeLamar in Fourth Quarter 2023.
