INTEGRA SUBMITS DRAFT MINE PLAN OF OPERATIONS FOR THE DELAMAR PROJECT
Vancouver, British Columbia – Integra Resources Corp. (“Integra” or the “Company”) (TSXV: ITR; NYSE
American: ITRG) is pleased to announce that it has submitted the Draft Mine Plan of Operations (“MPO”)
to the U.S. Bureau of Land Management (“BLM”) for the DeLamar and Florida Mountain Project
(“DeLamar” or the “Project”) located in southwestern Idaho.
MPO Highlights:
• The MPO is the culmination of over 3 years of environmental baseline studies, initial engineering
design, and detailed description of mining and reclamation activities proposed for DeLamar.
o The substantive MPO document was compiled over the last 6 months and allow s the
Company to initiate the Draft Environmental Impact Statement (“DEIS”) process and
begin work on the ancillary permits necessary to bring DeLamar to a production decision.
o The MPO submittal will initiate the BLM’s review process, per the United States Code of
Federal Regulations Title 43 Subpart 3809, allowing the BLM to make a completeness
determination and initiate the N ational Environmental Policy Act (“NEPA”) process,
expected to begin in mid-2024.
• The MPO includes information derived from various baseline studies completed between 2020-
2023, including:
o Wildlife
o Vegetation
o Soils
o Air Quality
o Cultural Resources
o Wetlands, Seeps and Springs
o Aquatic Resources
o Surface Water and Groundwater sampling, analysis and hydrologic studies
o Geochemistry
• The submission of the MPO signifies a major step forward in the mine permitting process as it will
utilize information obtained through the baseline studies to establish existing baseline conditions
at the DeLamar site to characterize potential impacts for the proposed mine action.
Integra’s President, CEO & Director, Jason Kosec commented: “We are incredibly proud of the team at
Integra for the submission of the MPO for DeLamar. This not only represents a critical milestone in the
advancement of the Project, but also sets Integra apart from its peers, being one of only a few
development companies in the Western U .S. with a project entering the NEPA permitting process. 2023
marks a pivotal and successful year for Integra with the completion of the merger with Millennial Precious
Metals Corp., announcing the maiden Preliminary Economic Assessment for Wildcat & Mountain View in
Nevada, filing the updated mineral resource estimate at DeLamar including the stockpiles, and finally the

submission of the MPO for DeLamar. These achievements continue to strengthen Integra’s position in the
Great Basin as a multi-asset developer with a pathway to becoming a leading U.S. focused gold and silver
producer.”
Mine Plan of Operations
Integra is dedicated to responsible mine planning that focuses on water quality and quantity, biodiversity
preservation, and community considerations. The submission of the MPO to the BLM is the first major de-
risking event in the mine permitting process and demonstrates the Company’s commitment to advancing
DeLamar towards a production decision. The MPO is an integral part of the NEPA process as it marks the
formal start of engage ment with all cooperating governmental agencies, stakeholders, and the general
public. The NEPA process will cover in -detail project scoping, environmental impact analysis, public
comment periods, and agency coordination. The detailed assessment conducted during this process
ensures a comprehensive understanding of the Project's potential impact on the environment and
surrounding communities.
The MPO includes preliminary engineering and site design to define pit layout, heap leach location ,
development rock storage facility design, and related sequencing. In addition, the MPO includes
placement of ancillary facilities, incorporating access roads, power generation, primary crushing and
processing. Integra’s engineering team has also completed multiple studies and drill programs over the
last 3 years to support the MPO which include geotechnical drilling, heap leach design, material and water
balance details, cover design, clay resource estimates, Kuz-Ram blast fragmentation study, updated mine
plans, and detailed power studies, among others.
Integra completed each of the baseline studies within the proposed outline of the mine features and
access roads in 2023 to support the MPO. The completed list of baseline studies was executed by the
following consultants:
Baseline Study Lead Consultant
Aquatic Resources – Fisheries & Macroinvertebrates EcoAnalysts, Inc. and BioAnalysts, Inc.
Wetlands, Seeps and Springs GeoEngineers Inc. and Haley & Aldrich, Inc.
Cultural Resources Tetra Tech, Inc.
Wildlife Environmental Resources Management, Inc.
Vegetation Cedar Creek Associates, Inc.
Soils Cedar Creek Associates, Inc.
Air Monitoring Ramboll Americas Engineering Solutions, Inc.
Surface Water Hydrology and Quality Arcadis U.S., Inc.
Groundwater Modeling and Quality Arcadis U.S., Inc.
Geochemistry SRK Consulting (U.S.), Inc.
In addition to the completed studies , geochemical characterization of encountered pit lithology and
hydrogeologic modeling studies (including fate and transport modeling) have been underway since 2022.
These studies will also be used to further develop the reclamation and closure plan at DeLamar.
Next Steps
During the MPO review process by the BLM, the Company will continue permitting efforts in anticipation
of the start of the NEPA and DEIS process at DeLamar. The baseline studies and MPO will serve as a basis
for various permits, some that are required to be in place prior to construction, includi ng Point of
Compliance Permitting, Cyanidation Permits , and Air Permitting with the I daho Department of
Environmental Quality as well as Section 404 of the Clean Water Act with the U.S. Army Corps of Engineers.

Upon receipt of a completeness determination from the BLM, Integra will begin the Notice of Intent
process which initiates development of the DEIS in mid-2024.
The Company will also continue Tribal engagement and initiate the Programmatic Agreement (“PA”)
process. The PA is a formal document established between the Company, governmental agencies, and
Tribal Nations. The PA includes framework for identifying, managing, and mitigating any potential impacts
on culturally sensitive areas or historical sites.
Sustainability Report
Integra recently published the latest Sustainability Report for DeLamar which outlines the Company's
commitments and performance in its Environmental, Social and Governance practices. The Sustainability
Report speaks to the vast amount of work various departments of the Company have completed,
advancing Integra’s vision for developing projects that generate an enduring positive legacy for both the
community and shareholders.
