Integra Resources Corp. announced additional drill results from the DeLamar Project (DeLamar or the Project) located in southwestern Idaho. The drill results announced on January 10, 2023 are from a metallurgical drill program at DeLamar as well as 24 additional drill holes from the 11,000 m stockpile drill program at the Project.

The stockpile drill program, the results of which continue to exceed expectations, has the potential to extend the heap leach mine life and positively impact the already robust economics of the DeLamar Project. Drill results from DeLamar stockpile drill program include: NDM-22-037: 0.25 grams per tonne (“g/t”) gold (“Au”) and 21.38 g/t silver (“Ag”) (0.52 g/t gold equivalent (“AuEq”)) over 102.11 m; NDM-22-040: 0.34 g/t Au and 18.19 g/t Ag (0.58 g/t AuEq) over 83.82 m; NDM-22-050: 0.28 g/t Au and 53.26 g/t Ag (0.97 g/t AuEq) over 24.38 m; NDM-22-136: 0.32 g/t Au and 14.28 g/t Ag (0.50 g/t AuEq) over 85.34 m NDM-22-147A: 0.32 g/t Au and 19.60 g/t Ag (0.57 g/t AuEq) over 42.68 m; NDM-22-143: 0.23 g/t Au and 19.25 g/t Ag (0.48 g/t AuEq) over 67.06 m. The company also announced drill results from metallurgical drill holes at DeLamar, including: IDM-22-211: 0.41 g/t Au and 75.37 g/t Ag (1.38 g/t AuEq) over 66.90 m Including 0.38 g/t Au and 1,251.00 g/t Ag (16.48 g/t AuEq) over 1.83 m; IDM-22-214: 0.62 g/t Au and 7.85 g/t Ag (0.72 g/t AuEq) over 32.00 m. The 11,000 m stockpile drill program at DeLamar continues to meet or exceed expectations in regard to grade and intercept. In addition, the preliminary test work has demonstrated the potential of this oxidized gold-silver mineralized material to further extend the heap leach mine life.

To date, the company has tested the North DeLamar backfill, Stockpile 1 and Stockpile 2. In total the company has drilled 3,980 m in 86 drill holes as part of this drill program. The remaining stockpiles will be drilled in the coming months. Due to the continued success of this drill program, the Company has increased the number of drills on site to three, including two sonic drill rigs and one RC drill rig at Jacob's Gulch on Florida Mountain.

Stockpile drilling completed has encountered primarily oxide material with some mixed material as well. Hot cyanide shakes are being performed on drilled material and suggest good heap leach recovery potential. Based on past metallurgical work at DeLamar, preliminary test work on mineralized material correlates well with bottle roll tests and column test work which will also be performed on this material in the future.

Work on these drill results at the assay lab shows average Au cyanide shake recoveries of greater than 70%.
