Integra Resources Corp. announced the second set of drill results from the 4,597 meter ("m") 2023 highwall geotechnical and metallurgical drill program at the DeLamar Project ("DeLamar" or the "Project") located in southwestern Idaho. The results announced include 20 drill holes representing 2,290 m from the highwall geotechnical and metallurgical drill program which was completed in November 2023.

The core samples from the drill program will be used for comprehensive mineralogical analysis, Crusher Work Index ("CWI") testing and additional heap leach recovery analysis, including bottle roll, permeability and column leach testwork. The metallurgical drill results from the program will be used to develop an advanced geo-metallurgical model that will support future economic studies at the Project. Geotechnical drilling was also completed in the proposed open pits at the Project to further bolster the 3D geotechnical model and to provide additional data for the Draft Mine Plan of Operations ("MPO"), which was submitted to the U.S. Bureau of Land Management ("BLM") in December 2023.

The latest drilling highlights from the Florida Mountain Deposit include: DH-FLM-23-MET02: 1.42 g/t grams per tonne ("g/t") gold ("Au") and 3.36 g/t silver ("Ag") (1.46 g/t gold equivalent ("AuEq")) over 134.11 m, including 103.57 g/t Au and 30.55 g/t Ag (103.96 g/t AuEq) over 1.52 m. Excluding the high-grade intercept, the residual grade of DH-FLM-23-MET02 is 0.25 g/t Au and 3.05 g/t Ag (0.29 g/t AuEq) over 132.59 m, which is above the cut-off grade of 0.17 g/t AuEq DM-FLM-23-MET09: 0.30 g/t Au and 17.03 g/t Ag (0.52 g/t AuEq) over 139.90 m, including 1.49 g/t Au and 437.00 g/t Ag (7.11 g/t AuEq) over 1.53 m. Excluding the high-grade intercept, the residual grade of DH-FLM-23-MET09 is 0.29 g/t Au and 12.39 g/t Ag (0.45 g/t AuEq) over 138.37 m, which is above the cut-off grade of 0.17 g/t AuEq DH-FLM-23-MET12: 0.35 g/t Au and 2.22 g/t Ag (0.38 g/t AuEq) over 80.47 m DH-FLM-23-MET15: 0.28 g/t Au and 3.58 g/t Ag (0.32 g/t AuEq) over 189.89 m The latest drilling highlights from the DeLamar Deposit include: DH-DLM-23-MET23: 0.27 g/t Au and 7.12 g/t Ag (0.36 g/t AuEq) over 84.89 m DH-DLM-23-MET24: 0.74 g/t Au and 115.94 g/t Ag (2.24 g/t AuEq) over 49.99 m, including 1.47 g/t Au and 263.48 g/t Ag (4.87 g/t AuEq) over 15.24 m. Excluding the high-grade intercept, the residual grade of DH-DLM-23-MET24 is 0.42 g/t Au and 51.23 g/t Ag (1.08 g/t AuEq) over 34.75 m, which is above the cut-off grade of 0.17 g/t AuEq. DH-DLM-23-MET33: 0.27 g/t Au and 24.90 g/t Ag (0.59 g/t AuEq) over 52.73 m DH-DLM-23-MET38: 0.45 g/t Au and 14.33 g/t Ag (0.64 g/t AuEq) over 74.98 m.
