• Follow-up drilling in the location of the 2019 drill program continues to demonstrate the presence of high-grade mineralization in steeply dipping shoots that extend from the volcanics down into the basement granite.
• The 2020 drill program has now identified two parallel mineralized structures 150 m apart that have strike lengths of over 500 m.

Integra Resources Corp. (TSX-V:ITR) (NYSE American: ITRG) is pleased to report a series of high-grade gold-silver drill results from the 2020 drill program at War Eagle Mountain, situated on the DeLamar Project in southwest Idaho.

“The drill results announced today once again demonstrate the occurrence of high-grade gold and silver at War Eagle, highlighting the potential for high-grade resource expansion on the DeLamar Project. These drill results further confirm the presence of a high-grade, steeply dipping mineralized structure in the location of the 2019 drill program. Multiple intersects of high-grade gold and silver were encountered in follow-up drilling and suggest the potential for high-grade gold-silver continuity in the north-northwest striking structure,” noted President and CEO George Salamis. “In addition to follow-up drilling in the location of the 2019 drill program, the Company also discovered a high-grade mineralized zone 400 m to the north of the 2019 drill holes. This second parallel structure has a strike extent of over 500 m and is largely untested. Our exploration team will look to incorporate the data from this exciting 2020 drill program at War Eagle as we further model the high-grade structures and plan an Induced Polarization study and drill testing for 2021 to further identify the target zones at War Eagle.”

War Eagle Drill Highlights:

The following table highlights selected intercepts from the War Eagle Mountain drill holes announced:

(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

2019 Drill Highlights:

The following table highlights selected intercepts from previously announced War Eagle Mountain drill holes. (See news release dated December 10, 2019)

(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)

War Eagle Mountain

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. All holes drilled this year at War Eagle intersected these mineralized zones to varying degrees, highlighting the presence of high-grade gold silver concentrations in the form of 100 m to 200 m strike lengths in steeply plunging shoots. In total, the Company drilled 3,675 m in 10 drill holes at War Eagle in the 2020 campaign.

In 2019, Integra discovered a large geochemical anomaly 300 m east of the 2019 drill campaign. In 2020, the Company drilled 5 drill holes into this anomaly, discovering the second, parallel mineralized structure at War Eagle. This second structure was drilled 400 m to the north of the 2019 drill holes and returned the highest-grade gold and silver assays of the 2020 campaign. This structure is currently modeled to have a strike length of approximately 550 m south-southeast and is largely untested. The geochemical soil anomaly that led the Company to this new structure is interpreted as being lateral leakage outward along the base of the latite flow, presumably emanating from the eastern most structure identified in this year’s drill program.

War Eagle: Next Steps

In 2021, the Company plans to complete an induced polarization survey at War Eagle, as well as further drill testing adjacent to some of the areas where high-grade was intersected in the 2019 and 2020 drill programs. IP has proven to be a valuable targeting tool at Florida Mountain, DeLamar and Blacksheep as it detects disseminated sulphide mineralization in the underlying rock that is in many cases gold and silver bearing. The IP program at War Eagle will follow-up on the geochemical survey completed in 2019 and the two drill programs to date. The majority of drilling thus far has identified mineralization within the capping volcanics. Intersecting high-grade mineralization within the volcanics is encouraging; however, most of the historical mining in the district took place in the underlying granite. The 2021 exploration drill program at War Eagle will focus on better defining the controlling structures in the underlying granite and defining the expected high-grade shoots which are anticipated to underly the diffuse cloud of mineralization present within the overlying volcanics.  

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 Laboratories 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.
