o IDE-22-228
▪ 4.10 grams per tonne (“g/t”) gold (“Au”) and 446.92 g/t silver (“Ag”) (9.85 g/t gold
equivalent (“AuEq”)) over 26.97 meters (“m”)

• The results from drill hole IDE -22-228 confirm for the first time the presence of a new, Northwest
trending structural zone hosting high-grade gold-silver dipping to the Northeast. All previous drilling
at Sullivan Gulch targeted a North -northwest structure dipping to the Southwest, suggesting these
new intercepts may represent a new, high -grade feeder system that has not been previously
encountered.
• This discovery demonstrates the future resource upside potential at the Project, including the highest-
grade silver intersect to date in drill hole IDM-22-228.
• The drill results reported today further validate the geological interpretation that a high-grade feeder
vein system exist s in conjunction with and amongst the low -grade, disseminated, bulk-tonnage
resource at Sullivan Gulch.
Vancouver, British Columbia – 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 Sullivan Gulch
exploration program that was intended to further define a high-grade gold-silver feeder system in
- 2 -
conjunction with the Sullivan Gulch bulk tonnage resource. Sullivan Gulch, in addition to targets at
DeLamar such as War Eagle, Florida Mountain and BlackSheep, show the future potential at DeLamar for
both resource expansion and mining scenarios.
President and CEO, George Salamis, notes: “The grades announced today are clearly spectacular and
represent some of the highest-grade gold and silver intercepts ever encountered on the project. The
immense value of the De Lamar project was recently highlighted in the February 2022 PFS Resource
Estimate which included a large gold and silver resource. This resource base tied into a robust mine plan
that demonstrated low-cost gold -silver production and a mining s cenario that we believe can be
permitted in a simple and straight-forward manner. As a potential new high-grade discovery, these results
announced today further underscore that resource upside is not at all capped, but in fact further
enhanced by results such as these shown today, as a large measure of today’s intercepts reside outside
of current resource limits and mine plans. The growth opportunities and project optionality remain
omnipresent at DeLamar. This has always been a key hallmark of the project and Integra has been adding
ounces to DeLamar at a discovery cost of approximately $10/oz AuEq. Furthermore, the Company has
increased the total resource on the project by approximately 76%, from no declared resources in 2017 to
those presented in the February 2022 PFS.” Mr. Salamis further adds, “Drilling to date at Sullivan Gulch
has delineated a mineralized zone over a strike length of 1,000 m with a width of 200 m and a depth extent
of up to 350 m. The mineralized area at Sullivan Gulch correlates with a strong Induced Polarization
chargeability footprint. This IP chargeability extends 900 m to the south be yond any existing drilling
completed by the Company, suggesting the mineralization at Sullivan Gulch continues on strike.”

Sullivan Gulch:
The high-grade results announced today build on the previous news releases from 2022 and are
particularly exciting due to the presence of an emerging high-grade vein system at Sullivan Gulch below
the existing low-grade, bulk tonnage resource. To date, drilling by the Company has focused on a North-
northwest trending vein system that dipped to the Southwest. Through geological modeling and
interpretation, the Company noted the possible presence of a Northwest trending vein system dipping to
the Northeast. In drill hole I DE-22-228, the Company turned the drill rig around to test the new vein
orientation and successfully hit both low-grade, bulk tonnage material along with a new high-grade vein
system below the resource. This new vein system at Sullivan Gulch is lithologica lly controlled in quartz
latite and is open to the south, laterally, and at depth.
In general, t he mineralization at Sullivan Gulch is largely hosted by porphyritic rhyolite and latite units,
capped by a banded rhyolite formation, all of which are of mid-Miocene age. The gold-silver mineralization
itself consists of a zone of moderately intense low -sulphidation epithermal veining, clay alteration and
related disseminated sulphides (mostly pyrite). Drilling to date at Sullivan Gulch has delineated
mineralization extending over a strike length of 1,000 m with a width of 200 m and a depth of 350 m. IP
indicates the potential for mineralization to extend a further 900 m to the south of the southern -most
drilled section of Sullivan Gulch.
Additionally, the Company’s success at targeting high-grade at Sullivan Gulch, including the results today
which have encountered a new vein system, suggests further optimization of the high-grade gold-silver
geological model at Sullivan Gulch.

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.
