Integra Resources Corp. (TSX-V: ITR) (NYSE American: ITRG) announces drill results from the 2021 Florida Mountain drill program at the DeLamar Project which continue to demonstrate the potential for a high-grade resource below the existing Florida Mountain Deposit. In addition, the Company is pleased to announce that it has received approval from the BLM authorizing an underground development and exploration drill program at Florida Mountain. This underground development and exploration drill program could begin at the Company’s discretion, subject to further on-going studies, and would allow for more efficient delineation of high-grade resources below the Florida Mountain resource envelope.


“The Company is excited that the team at the BLM, working alongside our environmental permitting staff in Boise, Idaho, granted Integra the approval through an EA authorizing an underground development and exploration drill program at Florida Mountain. We are obviously very pleased with this news which we view as a positive endorsement for responsible resource development and exploration at the DeLamar Project. The Company will engage third-party contractors to create a plan to potentially develop, at the Company’s discretion, underground access at Florida Mountain to pursue an underground exploration drill program,” stated Integra President and CEO George Salamis. “An underground exploration drill program, subject to the outcome of on-going studies, would allow the Company to drill the existing high-grade gold-silver structures far more efficiently on tighter drill spacings and with less drill meters than that which could be accomplished from surface drilling alone. Other potential operating efficiencies include the ability to work in all seasons at Florida Mountain, from underground drill stations, as well as to conduct limited bulk sampling on high grade gold-silver mineralization.


Mr. Salamis continued, “Exceptional drill results like those reported today continue to show the potential for resource growth at Florida Mountain. These results include both long runs of higher-grade mineralization within the pit as well as continued high-grade hits below the existing resource envelope at Florida Mountain. The Company has now intersected 110 drill intercepts of 4 g/t AuEq or greater with a minimum width of 1.52 m at Florida Mountain, demonstrating the potential to complement the robust low-grade resource at surface with a high-grade resource at depth. The potential to add a high-grade resource below Florida Mountain, subject to on-going studies, could further enhance the robust economics of the recently released PFS by increasing the grade of the material being processed through the contemplated mill.”

The Florida Mountain Underground Mineral Exploration Plan of Operations


The BLM has conducted an EA (DOI-BLM-ID-B030-2022-0001EA) for Integra Resources’ DeLamar Mining Company’s proposed underground development and exploration drill program at its current operation in Owyhee County, Idaho. The proposed project would include the construction of an underground portal pad in the historic mining area of Blue Gulch, exploration drifting into Florida Mountain, the establishment of drill stations perpendicular to the veins and an underground exploration drill plan. Based upon a review of the EA and DMC’s commitments to minimizing environmental effects during construction, operation, and reclamation of the proposed project, BLM has determined that the Stone Cabin Mine Underground Portal Plan of Operations Amendment was not a major federal action and did not significantly impact the quality of the human environment. As defined by Code of Federal Regulations an environmental impact statement was not needed for this action. A Finding of No Significant Impact was signed allowing the Company to move forward with detailed design and subsequent construction activities.


The Company has now intersected 110 intercepts of 4 g/t AuEq or greater with a minimum width of 1.52 m. The drill success below the existing resource envelope at Florida Mountain continues to demonstrate the potential for a high-grade resource below the Florida Mountain Deposit, which was recently the subject of a PFS. None of these high-grade intercepts have been included in a Resource Estimate to date. Including a high-grade resource into the mine plan laid out in the PFS has the potential to further enhance the economics of the mill. Florida Mountain Non-Oxide material, which includes the high-grade intersects disclosed today, could be processed through the existing mill flow sheet based on known metallurgy. Increasing the grade and material run through the mill has the potential to increase production profile for both gold and silver.


Select intercepts from drill holes FME-21-130, FME-21-132 and FME-21-135 were rushed at the laboratories and previously reported (please see the Company news release dated August 31, 2021). The remaining portions of these drill holes were announced today in the table above.


Current Drill Status


The Company currently has 1 drill rig in operation at Sullivan Gulch. This drill rig is testing the extensions of the Sullivan Gulch target while providing crucial data for further Albion test work.


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.
