INTEGRA INTERSECTS 1.46 g/t AuEq OVER 134 M IN METALLURGICAL DRILL PROGRAM AT DELAMAR

 

 

 

 

 

Integra Resources Corp. (TSX-V: ITR) (NYSE American: ITRG) is pleased to announce the second set of drill results from the 4,597 meter 2023 highwall geotechnical and metallurgical drill program at the DeLamar Project located in southwestern Idaho. The results announced today 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 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 which was submitted to the U.S. Bureau of Land Management in December 2023.

 

Drilling Highlights:

  • The latest drilling highlights from the Florida Mountain Deposit include:

(1) Cut-off grade described in NI 43-101 technical report titled: “Technical Report and Preliminary Feasibility Study for the DeLamar and Florida Mountain Gold-Silver project, Owyhee County, Idaho, USA”, dated October 31, 2023 with an effective date of August 25, 2023, available under Integra’s SEDAR+ profile at www.sedarplus.ca

 

Integra’s President, CEO & Director, Jason Kosec commented: “The drill results announced today further demonstrate the size, grade, and continuity of the mineral resource at DeLamar. Although the drill program was primarily designed to collect material for heap leach metallurgical testwork and geotechnical studies, we continue to intercept significant mineralized widths at excellent grades throughout the Project, exemplifying the robust nature of DeLamar. The results from this drill program will be used to complete a Feasibility Study at DeLamar in the future and to support on-going permitting work at the Project, following the submission of the MPO to the BLM in December 2023.”

(2) Intervals reported are uncapped.
(3) AuEq = g/t Au + (g/t Ag ÷ 77.70). Rounding may cause minor discrepancies in the AuEq column.
(4) Certain intervals were not sampled because they were utilized for alternative purposes requiring intact core (i.e. – geotechnical analysis, additional metallurgical tests). These unsampled intervals (~1% of the total program footage) have been replaced by ‘zero grade’ for the purposes of this news release.

Sampling and QA/QC Procedure

 

Thorough QA/QC protocols are followed on the Project, including insertion of duplicate, blank and standard samples in the assay stream for all drill holes. The samples are submitted directly to American Assay Labs in Reno, Nevada for preparation and analysis. Analysis of gold is performed using fire assay method with atomic absorption (“AA”) finish on a 1 assay ton aliquot. Gold results over 5 g/t are re-run using a gravimetric finish. Silver analysis is performed using ICP for results up to 100 g/t on a 5-acid digestion, with a fire assay, gravimetric finish for results over 100 g/t silver.
