Vancouver, British Columbia – Integra Resources Corp. (“Integra” or the “Company”) (TSX-V: ITR; NYSE American: ITRG) is pleased to provide an update on various permitting activities that have been underway since 2020 in anticipation of the filing of the Mining Plan of Operations in Q4 2023. The review and approval process for the MPO by the BLM constitutes a federal action under the National Environmental Policy Act (“NEPA”) and BLM regulations. The MPO is the basis for the impacts to be analyzed during the NEPA process. Alternatives in the MPO are required for scoping in NEPA process, as well as for geochemical characterization and groundwater modeling. Potential disturbances and anticipated impacts provided in the MPO will be the basis for all federal, state, and local permitting efforts.
“The Company continues to push the DeLamar Project forward on two fronts: de-risking DeLamar through permitting and expanding the resource through drilling. On the permitting front, many key studies are well advanced. The Company has initiated baseline studies designed to ensure data collection and/or monitoring since 2020. These studies, among other items, will be fed into an MPO to be filed in late 2023,” noted President and CEO George Salamis. “On the second front, we are excited to announce that the Company has commenced a drill program on the historic low-grade gold-silver stockpiles that were mined and stored by previous operators. The 11,000 m drill program is aimed at growing the oxide resource to potentially expand future heap leach operations at DeLamar. This material once successfully defined, could result in a significant amount of low-cost gold-silver mineralized material being added to future mine plans at DeLamar. These stockpiles, much of which were to be moved as part of the pre-stripping cost in the Company’s Pre-feasibility Study, have the potential to further enhance both the economics and mine life of DeLamar.”
To date, the Company has completed more than 80% of the required fieldwork for the baseline studies associated with the proposed mine features at DeLamar. These baseline studies have been ongoing since 2020 and the remaining 20% of required study will be finished during the 2023 field season. The baseline studies include:
|Baseline Study||Lead Consultant|
|Aquatic Resources||EcoAnalysts, Inc. and BioAnalysts, Inc.|
|Wetlands, Seeps and Springs||GeoEngineers Inc. and Haley & Aldrich|
|Cultural Resources||Tetra Tech Inc.|
|Vegetation||Cedar Creek Associates, Inc.|
|Soils||Cedar Creek Associates, Inc.|
|Surface Water Hydrology and Quality||Brown and Caldwell|
|Ground Water Modeling and Quality||Brown and Caldwell|
Long lead-time studies, such as groundwater modeling and geochemical characterization, were initiated in 2021. Groundwater and geochemical modeling will aid in the determination of required reclamation activities as well as the basis for various permits required to be in place prior to construction including Idaho Department of Environmental Quality (“IDEQ”) Point of Compliance, Section 404 of the Clean Water Act, and Cyanidation Permit.
Ongoing engineering design is underway and the team is refining the placement of facilities, pit design, mining sequence, geotechnical investigations, and material processing to develop a complete and accurate MPO. Other elements such as transportation, energy needs, and public safety are also under development. The Reclamation Plan, an essential element of the MPO, will be completed in 2023.
The Company has been working closely with the BLM since signing a Memorandum of Understanding with the agency in August 2020 to facilitate the hiring of a dedicated mineral specialist in the Marsing, Idaho BLM office (please refer to the Company’s press release dated August 20, 2020 for further details). SWCA Environmental Consultants has been selected as the third-party consultant to the BLM.
Permitting / Engineering Planned Activities – 2022-2023:
The following activities are on-going or will begin soon for the MPO:
- Continued geotechnical studies
- Continued condemnation drilling
- Waste rock/mineralized material stockpile capacities
- Site-wide water balance determination
- Reclamation and continued identification of closure materials
- Continued Agency coordination on MPO development
Oxide Expansion Drill Program:
The Company has commenced an 11,000 m drill program at DeLamar using a sonic drill rig. The drill program will test approximately 60 million tonnes (“Mt”) of low-grade gold-silver mineralized material that was stockpiled and/or used as backfill by previous mine operators at DeLamar from the 1970s to the late 1990s. The estimated cut-off grade used by previous operators ranged from 0.80 g/t AuEq and 0.90 g/t AuEq, a cut-off significantly above that used in the Company’s Pre-feasibility Study and suggesting that a significant amount of the 60 Mt of stockpiled material could potentially be amenable to heap leaching. As this material has already been mined and segregated close to or within existing planned mining infrastructure, with the associated mining and stripping costs already incurred by the previous mine operators, this material has the potential to be a source of low-cost gold and silver production in future mine plans.
The stockpile drilling program will be executed at 60 m collar spacing with select 30 m infill test holes. All drilling will be vertical through the entirety of the stockpiles. Sampling will be conducted at 1.5 m intervals for the whole of the drilling with all samples sent to a third-party lab for analysis. Bottle roll testing will be conducted on crushed material and column leach testing is planned for select material obtained with the sonic drill.
Integra’s ESP outlines a Social Performance Management approach that is implemented through a set of objectives that, together, constitute the Company’s approach to stakeholder management: 1. Stakeholder Engagement 2. Communications 3. Community Involvement and Support 4. Monitoring and Reporting. The strategies and objectives of the ESP continually evolve as Integra’s staff experience the culture, values, and priorities of the communities surrounding the DeLamar Project. These four primary objectives continue to provide the foundational elements of the Company’s Social Performance Management.
Recent key priorities have focused on establishing formal policies, procedures, and objective metric-tracking mechanisms to bolster the Company’s ESP. These tools establish qualitative Key Performance Indicator (“KPI”) measurement tools which can be tracked year over year to better understand the Company’s performance. Additionally, these tools serve to embed the four tenants of the ESP into the cultural fabric of Integra as a company now and into the future through formal adoption of procedures and Company-wide participation.
With all stakeholder engagement activities, Integra leads with its Core Values of Integrity, Care, and Innovation. Heavy focus is placed on listening to stakeholders and ensuring that programs and partnerships align with the culture, values, and priorities of our diverse stakeholder groups. Integra focuses on being an active partner in the community, directing our efforts towards developing lasting, mutually understanding relationships and generating shared value for all stakeholders, as well as for the DeLamar Project.
Highlighting Integra’s commitment to responsible and long-term stakeholder management, in 2021 the Company brought on a dedicated Community Affairs Manager. This position focuses on direct stakeholder engagement and leads the implementation of Integra’s ESP.
Sampling and QA/QC Procedure
Thorough QA/QC protocols are followed on the DeLamar 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.
