INTEGRA ANNOUNCES ADDITIONAL OXIDE DRILL RESULTS FROM STOCKPILE DRILL PROGRAM AT
DELAMAR, INCLUDING 0.70 g/t AuEq OVER 85 M AND 0.60 g/t AuEq OVER 44 M
Vancouver, British Columbia – Integra Resources Corp. (“Integra” or the “Company”) (TSXV: ITR; NYSE
American: ITRG) is pleased to announce drill results from 20 additional drill holes , representing 4,960
meters (“m”), from the recently completed stockpile drill program at the DeLamar Project (“DeLamar” or
the “Project”) located in southwestern Idaho. The Company is also pleased to provide a corporate update
regarding several of its properties located in western Nevada, which were acquired as part of the merger
with Millennial Precious Metals Corp.
The stockpile drill program at DeLamar was designed to test a large portion of the estimated 60 million
tonnes (“Mt”) of mineralized material that was stockpiled and/or used as backfill at the Project . The
Company believes that additional oxide-and-mixed material from the stockpiles and backfill at DeLamar
has the potential to significantly increase the heap leach mine life of the Project in future phases and
further bolster the robust economics presented in the Company’s 2022 Pre-feasibility Study.
Drilling Highlights
• The Company has released 135 drill holes of the 321 drill holes completed during the 12,588 m
stockpile drill program which was completed in April 2023.
• The latest drill results from DeLamar (North DeLamar (“NDM”), Sommercamp, Stockpile 1 and 2 )
include:
o NDM-23-129: 0.40 grams per tonne (“g/t”) gold (“Au”) and 23.67 g/t silver (“Ag”) (0. 70 g/t
gold equivalent (“AuEq”)) over 85.34 m
o NDM-23-049: 0.34 g/t Au and 20.14 g/t Ag (0.60 g/t AuEq) over 44.20 m
o NDM-23-048: 0.26 g/t Au and 20.63 g/t Ag (0.53 g/t AuEq) over 88.39 m
o NDM-23-029: 0.26 g/t Au and 22.89 g/t Ag (0.55 g/t AuEq) over 79.25 m
o WD1-23-061: 0.18 g/t Au and 39.79 g/t Ag (0.69 g/t AuEq) over 21.34 m
• The latest drill results from Florida Mountain (Jacobs Gulch) include:
o JG-23-119: 0.45 g/t Au and 8.45 g/t Ag (0.56 g/t AuEq) over 67.06 m
o JG-23-088: 0.40 g/t Au and 7.55 g/t Ag (0.50 g/t AuEq) over 41.15 m
o JG-23-189: 0.43 g/t Au and 28.88 g/t Ag (0.80 g/t AuEq) over 13.72 m
• The drill results announced today continue to demonstrate excellent gold equivalent grade and drill
intercept widths with strong continuity throughout the stockpiled and backfill mineralized material.
• The Company has 7,368 meters of assays pending.

• Integra is currently focused on achieving several key milestones in 2023, including an updated mineral
resource estimate and the submission of the Mine Plan of Operations at DeLamar, as well as an
updated mineral resource estimate and Preliminary Economic Study at the Wildcat & Mountain View
Projects, located in western Nevada.
Integra’s President, CEO & Director, Jason Kosec commented : “we are pleased to see more successful
drill results from the stockpile drill program which demonstrate the strong continuity of mineralization
within the previously mined material at DeLamar and Florida Mountain. The grade and intervals
intercepted in this drill program have exceeded the team’s expectations and are in-line with or better
than our original estimates, highlighting the potential for this material to significantly increase the heap
leach mine life of the Project in future phases.”

The NDM stockpile cross section demonstrates the strong grade continuity with in the mineralized
stockpiles, with consistent grades above the heap leach cut-off grade. Assays are pending for drill holes
NDM-23-146 and NDM -23-046, however, the Company expects th e results to be in line with the other
drilling completed at the NDM stockpile. The NDM stockpile is estimated to contain approximately 16 Mt
of the approximate 60 Mt of mineralized material that was stockpiled and/or used as backfill by previous
operators. Drill spacing is completed at 60 m with some areas drilled at 30 m spacing to further confirm
continuity. The stockpile drilling, along with additional drilling tha t occurred after the last resource
estimate cut-off date, will be included in an updated resource estimate at the Project.

Cyanide shake analysis is not performed on Florida Mountain samples as g old occurrences in Florida
Mountain material can often be coarse in nature, making comparisons between cyanide shake analyses
and fire assays unreliable. Once pulverized, as per any cyanide shake procedure, all Florida Mountain
material show high recoveries by cyanidation, rendering cyanide shake analysis unreliable for
differentiating between ores that can be heap leached and those requiring gr inding to achieve high
recoveries.

Corporate Update – Final Land Payment for Nevada Properties
On June 6, 2023, the Company completed the final land payment of US$2.5 million to Clover Nevada LLC,
a private company controlled by Waterton Precious Metals Fund II Cayman, LP (“Waterton”), to complete
the acquisition of the Wildcat Property, the Mountain View Property, the Ocelot Property, the Dune
Property, the Eden Property, and the Marr Property (together, the “Nevada Properties”). Following
completion of the final payment, Waterton’s deed of trust encumbering the Nevada Properties was
released and title now resides with the Integra subsidiaries.
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 submit ted 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 fini sh. 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.
Execution of Drill Program – Methodology
The stockpile drill program was executed at 60 m collar spacings with select 30 m infill test holes to further
verify grade variability in future resource estimation and to provide additional metallurgical samples. All
drilling was vertical through the entirety of the stockpiles and backfill material. The drilling was conducted
by a combination of Sonic and traditional reverse circulation (“RC”) with casing advance drilling methods.
Both these drilling methods maintain high sample quality and integrity throughout the drilling process.
Additionally, the two drilling methods provided a basis for continuity comparison. Sampling was
conducted at 1.5 m intervals for the whole of the drilling program with all samples sent to a third -party
lab for analysis. The Sonic Drilling provided material suitable for ongoing comprehensive metallurgical test
work.
