Metallurgical Drill Program Intersects At The DeLamar Project

Metallurgical Drill Program Intersects At The DeLamar Project

VANCOUVER – Integra Resources Corp. reported on the 4,597 meter (m) 2023 highwall geotechnical and metallurgical drill program at the DeLamar Project located in southwestern Idaho. The results include 10 drill holes representing 1,376 m from the drill program. The highwall geotechnical and metallurgical drill program was completed in November 2023. The material from this drill program will be used for comprehensive analysis including mineralogical characterization and Crusher Work Index (“CWI”) testing, as well as bottle roll, permeability, and column leach testwork to better understand characteristics for future heap leach mining. In addition, geotechnical drilling was completed in the proposed open pits at the Project to evaluate the stability of high walls and to provide more information for the 3D geotechnical model. The drill program was completed in support of the Draft Mine Plan of Operations (“MPO”) and to gather additional data for a future Feasibility Study on the Project.

The latest drilling highlights from the DeLamar Deposit include: 1) DH-DLM-23-MET22: 0.76 grams per tonne (g/t) gold (Au) and 257.43 g/t silver (Ag) (4.07 g/t gold equivalent (AuEq)) over 41.45 m. 2) DM-23-MET-P11: 0.40 g/t Au and 21.58 g/t Ag (0.67 g/t AuEq) over 54.86 m.  

The latest drilling highlights from the Florida Mountain Deposit include: 1) DH-FLM-23-MET03: 0.74 g/t Au and 13.28 g/t Ag (0.91 g/t AuEq) over 157.43 m. 2) DH-FLM-23-MET04: 0.91 g/t Au and 13.46 g/t Ag (1.09 g/t AuEq) over 69.50 m. 3) DH-FLM-23-MET13: 0.54 g/t Au and 6.62 g/t Ag (0.63 g/t AuEq) over 99.97 m.

The drill results demonstrate the strong continuity of mineralization at DeLamar, including multiple drill holes with mineralization beginning at surface.

President, CEO & Director, Jason Kosec. said, “The drill results announced today come from a program primarily designed to collect additional gold-silver mineralized material for metallurgical and geotechnical testing. Intersecting significant widths of mineralization in metallurgical and geotechnical drilling demonstrates the strong resource continuity at DeLamar. Furthermore, mineralization beginning at surface in multiple drill holes highlights the low-strip ratio at the Project with minimal waste or overburden sitting above in-situ resource. With the MPO submitted to the Bureau of Land Management in December 2023, DeLamar is one of the few precious metal projects in the USA which is entering the National Environmental Policy Act permitting phase and actively being advanced towards a production decision.”
