Draft Mine Plan Of Operations For The DeLamar Project

VANCOUVER - Integra Resources Corp. reported 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 located in southwestern Idaho.

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. The substantive MPO document was compiled over the last 6 months and allows 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.

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 National Environmental Policy Act (NEPA) process, expected to begin in mid-2024. The MPO includes information derived from various baseline studies completed between 2020-2023. 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.

President, CEO & Director, Jason Kosec, said, “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.”

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 engagement 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.
