VANCOUVER, BC

,

May 30, 2024

/CNW/ -

Integra Resources Corp. ("Integra" or the "Company")

(TSXV: ITR) (NYSE American: ITRG) is

pleased to provide an overview of the upcoming exploration drill campaign at the Wildcat Deposit ("Wildcat"), which combined with the

Mountain View Deposit form the Nevada North Project (the "Project"). Wildcat is located within the Farrell mining district in northwest Nevada,

56 kilometers ("km") (~35 miles) north of the town of

Lovelock

, in

Pershing County

. The 17,612-acre land package consists of 916 unpatented

claims and 4 patented claims. Mineralization at Wildcat consists of a gold-dominated, low sulphidation, epithermal vein system with

disseminated oxide, transition, and non-oxide mineralization hosted in permeable volcanic and intrusive rocks.

The Company intends to complete a ~2,000 meter ("m") Phase 1 exploration drill program at Wildcat, commencing in

June 2024

. The drill

program is designed to test the oxide mineralization adjacent to the existing mineral resource at Wildcat, while also testing the high-grade

breccia target which is believed to be the feeder source of gold mineralization at Wildcat. The planned drill program is the first time Integra's

team will complete a significant follow up exploration program since the Company acquired the Project as part of the merger with Millennial

Precious Metals Corp. ("Millennial") in 2023. The Company believes that Phase 1 drilling has the potential to significantly increase the existing

mineral resource at Wildcat by testing high-priority targets that could not be drilled previously due to permit restrictions.

Highlights:

Wildcat currently hosts a mineral resource of

746,297 ounces ("oz") of gold ("Au") and 6,437,869 oz of silver ("Ag") or 829,152 oz of

gold equivalent ("AuEq")

in the Measured and Indicated Category ("M&I") (59,872,806 tonnes at 0.39 g/t Au and 3.34 g/t Ag) and

209,662 oz Au and 1,980,129 oz Ag or 235,146 oz AuEq

in the Inferred Category ("Inf.") (22,455,848 tonnes at 0.29 g/t Au and 2.74 g/t

Ag).

The 2023 Nevada North Preliminary Economic Assessment ("PEA") demonstrated strong project economics including an

after-tax

Net Present Value ("NPV")

5%

of

US$310 million

(

C$409 million

1

) and a 37%

after-tax Internal Rate of Return ("IRR")

using

base case metal prices of

US$1,700

/oz Au and

US$21.50

/oz Ag.

2

Using recent metal prices of

US$2,000

/oz Au and

US$23.00

/oz Ag, the Nevada North Project delivers an

after-tax NPV

5%

of

US$490 million

(

C$647 million

) and a ~54% after-tax IRR

.

Previous drilling at Wildcat completed by Millennial focused primarily on the Main Hill target which hosts the existing mineral resource. The

upcoming drill campaign will test multiple underexplored targets outside the Main Hill area at Wildcat, which have demonstrated the

potential to host additional mineralized material at Wildcat.

The 2,000 m Phase 1 exploration drill program will focus on achieving three main objectives:

Oxide resource expansion:

The 2022 exploration program at Wildcat completed by Millennial increased the mineralized footprint

from ~1.5 km by 1.5 km to ~3.0 km by 2.0 km through the collection of ~850 rock samples. Of these samples, ~99% were collected

outside the proposed PEA pit and ~200 were above cut-off grade

2

. Three priority areas were identified within the expanded

mineralized footprint, including the Crossroads, Breccia Pipe, and Rhyolitic Ridge targets. The 2024 drill program will be the first time

the expanded mineralized footprint will be drill tested by the Company with the goal of increasing the oxide mineral resource in future

studies. See Figure 1 for target locations and overview of 2022 grab sample program.

Testing high-grade Breccia Pipe target at depth:

Significant geophysical, magnetic, and chargeability anomalies were interpreted

below post-mineralization basalts

800 m

north from the Main Hill resource. These anomalies are interpreted to be the potential

location of high-grade epithermal feeder veins which will be drilled as part of the Phase 1 program. A discovery at the Breccia Pipe

Target has the potential to materially augment both the size of the mineral resource and potential future economics at Wildcat. See

Figure 2 for Wildcat schematic long sections with geophysics.

Metallurgical and geotechnical testing:

Strategic drilling will be executed within the proposed PEA pit to collect additional material

for future economic studies. Column leach tests completed for the 2023 PEA demonstrated excellent leachability of the tuff material

(~75% of the in-pit mineralized material) with oxide recoveries up to ~80%. Test work planned in 2024 will seek to further optimize

and improve the variability, size sensitivity, and kinetics observed within the tuff material. Further testing will also help the team better

understand recoveries in the granodiorite (~25% of the in-pit mineralized material) which had recoveries of 52% in the 2023 PEA.

2

Integra has observed a strong correlation at Wildcat between the presence of historical mines and the location of mineralization. Of the

~25 historical mines and adits located on the property, only 8 are located within the proposed PEA pits, suggesting a strong potential for

new areas of mineralization at the targets designated for drilling in 2024.

Jason Kosec

, President, CEO and Director of Integra commented

: "We are extremely excited to kick off the much-anticipated 2024 drill

program at Wildcat. The planned program is the first significant exploration drilling program at Wildcat since the deposit was explored by

Millennial in 2022, when five new mineralized targets were discovered outside the 2023 PEA pit. We believe this drill program has the potential

to significantly increase the near surface oxide mineral resource which will enhance future economics at Wildcat. Moreover, the discovery of

the main feeder zone could be a potential game changer for Wildcat, altering the scope of what we currently know about the potential size of

the deposit."

Overview of Previous Millennial Exploration at Wildcat

In 2022, Millennial completed both drilling and a detailed mapping and sampling program at Wildcat. The sampling program included detailed

surface mapping, a robust rock chip sampling program (~850 samples, ~23% of samples returned grades above 0.1 g/t Au), and detailed

compilation of historic data. The mapping program successfully increased the mineralized footprint at Wildcat from ~1.5 km by 1.5 km to ~3.0

km by 2.0 km. Infill and metallurgical drilling which took place at Wildcat in 2022 was highly successful, demonstrating strong grade continuity,

minimal overburden coverage, and excellent rock mechanics allowing for favourable pit wall angles and the potential to reduce stripping

volumes and lower mining costs. Wildcat demonstrates an extremely low-strip ratio of 0.28 Life-of-Mine ("LoM"), which is presented in the

2023 PEA (

Nevada North LoM

strip ratio of 1.21). See Figure 3 for a cross section providing an overview of the mineralization at Wildcat.

2024 Exploration Drill Program at Wildcat

The 2024 exploration drill program at Wildcat will test the expanded mineralized footprint at Wildcat identified by Millennial in 2022. The drill

program will focus on greenfield exploration targets that have the potential to expand the oxide mineral resource at Wildcat. Material will also

be collected for metallurgical and geotechnical testing to be used in future studies.

The greenfield portion of the 2024 drilling program will focus on three primary targets:

Breccia Pipe Target

: One of the main objectives for the 2024 program is to drill into the previously untested high-grade Breccia Pipe

target. Located approximately

800 m

north of the Main Hill resource, this target was identified through a combination of conceptual

metallogeny and recompilation of geophysical information. Considering the abundance of rhyolite tuff in the area, a large volcanic

diatreme, which is a strong indicator of highly permeable conduits for gold rich hydrothermal fluid, is not present at surface. The absence

of a diatreme on surface suggests it may be located below the post-mineralization basalts to the north. Using pre-existing geophysical

data, a new 3D model was developed that showed significant magnetic and chargeability anomalies immediately below the basalts.

Magnetic and chargeability anomalies in this area indicate high sulphur content which is generally associated with magnetite, pyrrhotite,

pyrite, or chalcopyrite and can be strongly correlated with gold bearing structures. The first three drill holes of the 2024 campaign are

targeting these anomalies.

Crossroads Target

: The Crossroads target is approximately ~1,300 m by

600 m

in size and is characterized by disseminated

mineralization within silicified tuff breccia. Of the ~36 samples collected at the Crossroads target in 2022, ~69% returned oxide grades

>0.10 g/t Au with values up to 2.44 g/t Au, suggesting that oxide mineralization extends into this target. The Crossroads target geology is

identical to Main Hill, however, most of the granodiorite located below the Crossroads target is not mineralized. This implies that the main

feeder structure of the gold mineralization at the Crossroads target may be a fault located east of the PEA pit. This fault will be tested for

high-grade potential at depth during the 2024 drill program.

Rhyolitic Ridge Target

: The untested Rhyolitic Ridge target consists of multiple large gold geochemical soil and geophysical anomalies.

Located approximately

300 m

east of Main Hill and presenting similar lithologies to the mineral resource area, Rhyolitic Ridge contains

significant soil anomalies with ~55% of the 116 samples tested returning grades above 0.1 g/t Au.

Wildcat Deposit Overview

Wildcat is located within the Farrell mining district in

Nevada

, 56 km north of the town of

Lovelock

within

Pershing County

. The property can be

accessed year-round by roads from

Lovelock

via State Route 399 and Seven Troughs Road. The 17,612-acre land package consists of 916

unpatented claims and 4 patented claims. The claims are located on publicly-owned lands administered by the U.S. Bureau of Land

Management.

Mineralization at Wildcat is genetically related to a mid-Miocene rhyolite dome complex developed during the extensional dominated tectonic

environment of the Nevada Rift. The bulk-tonnage gold mineralization is hosted in tuff breccia that is considered to be the erosional remnant of

a subaerial apron to a phreatomagmatic diatreme vent. The tuff breccia-hosted gold mineralization was fed from low-sulphidation veins in the

underlying Mesozoic granodiorite basement. Additional bulk-tonnage gold mineralization associated with tuff breccia may be present elsewhere

within the district, particularly beneath a post-mineral mafic volcanic cover sequence and within the interpreted main feeder diatreme. Low-

sulphidation epithermal veins beneath the tuff breccia have the potential to host high-grade gold targets.
