Approval To Proceed With Underground Development And Exploration Drill Program At Florida Mountain

VANCOUVER - Integra Resources Corp. reported on 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.

Exceptional drill results like 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.”
