- The 2021 drill results announced today from War Eagle are an extension of areas previously drilled by the Company, indicating the potential for a high-grade gold-silver system in the granites below previous drilling.


VANCOUVER, May 05, 2022 - Integra Resources Corp. (“Integra” or the “Company”) (TSX-V: ITR; NYSE American: ITRG) is pleased to announce drill results from the DeLamar Project (“DeLamar” or the “Project”) located in southwestern Idaho. The results announced today are from the 2021 drill campaign at the War Eagle target, located approximately 3 km southeast from Florida Mountain. War Eagle continues to deliver high-grade gold-silver intercepts which are on extension from previous drilling, suggesting the presence of additional high-grade gold silver mineralization at depth and on strike.

“The vast exploration potential at the DeLamar Project has always been one of the hallmarks of the Project. War Eagle has always been an attractive high-grade target at DeLamar with a rich history of historic underground mining of high-grade gold-silver. The drill results announced today are on extension from previous drilling at War Eagle and continue to demonstrate the high-grade potential at this target. The Company has now identified multiple high-grade gold-silver mineralized structures at War Eagle with strike lengths of up to 500 m,” noted Integra President and CEO George Salamis.

The following table highlights selected intercepts from the 2021 War Eagle drill results announced today:

(1) Downhole thickness: true width varies depending on drill hole dip; most drill holes are aimed at intersecting the vein structures close to perpendicular therefore true widths are close to downhole widths (approximately 70% conversion ratio)
(2) Gold equivalent = g Au/t + (g Ag/t ÷ 77.70)
(3) Intervals reported are uncapped


War Eagle Target:

Drilling at War Eagle has identified two parallel mineralized structures approximately 150 m apart with strike lengths of over 500 m. These principal structures host high-grade gold and silver mineralization associated with quartz-pyrite veinlets within rhyolite breccias and brecciated volcano-sediments. The mineralization identified to date within the volcanics is considered to be within the diffuse cap which sits above the modelled high-grade veins within the underlying granite. The broad distribution of mineralization delineated by the soil geochemical anomalies indicates considerable lateral dispersion of mineralization within the permeable volcanic cap, possibly from a structure several hundred meters east of the known mineralized structures.

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.
