Borealis Mining has initiated a detailed engineering, permitting, and technical work programs at its Sandman Gold Project in Humboldt County, Nevada, as the company advances the project toward a future construction decision.
Following the results of its recently completed preliminary economic assessment, Borealis has transitioned Sandman into an execution-focused phase, advancing engineering, metallurgy, and permitting in parallel to systematically de-risk the project and progress it toward a buildable, development-ready gold operation.
“Following the results of our updated preliminary economic assessment, our focus at Sandman is now firmly on execution. We have initiated detailed engineering, drilling, metallurgical, and permitting workstreams with the objective of advancing the project toward a construction decision. Importantly, we are well-financed to complete this phase of work and systematically advance Sandman toward development,” said Kelly Malcolm, president and CEO of Borealis.
“Sandman is a straightforward Nevada heap leach project with strong economics and a clear path to development. As our primary development asset, it complements our ongoing mining and production activities at the Borealis Mine and represents the next stage of growth within our Nevada platform. Our priority is to define a buildable project, de-risk the asset, and position it for a disciplined transition into production,” added Malcolm.
Borealis has engaged a group of leading engineering, technical, and legal firms with extensive Nevada experience to support this next phase of advancement.
M3 Engineering & Technology Corporation has been engaged as lead engineering firm, responsible for overall coordination of engineering design and study activities. RESPEC Company has been engaged to support mining, geology, resource modeling, hydrogeology, geotechnical work, and environmental inputs to the integrated development plan.
Work programs underway are designed to advance Sandman from a scoping-stage project toward a technically defined, buildable gold operation.
In parallel with engineering activities, Borealis has initiated environmental baseline and permitting programs to support a clear pathway toward mine development. Workstreams are focused on environmental data collection, regulatory engagement, and permitting strategy development, positioning the project for efficient advancement through the permitting process.
Borealis is executing a series of parallel workstreams to systematically de-risk Sandman and advance the project toward a construction decision.
Key milestones include:
• Drilling Programs
Targeted drilling campaigns to support conversion of inferred mineral resources to measured and indicated categories, while also testing for resource expansion across the broader property.
• Metallurgical Testwork
Completion of column leach testwork and associated metallurgical programs to further define recoveries, reagent consumption, and processing parameters at a development-ready level.
• Engineering and Mine Planning
Advancement of detailed mine design, pit optimization, infrastructure layout, and process engineering to support a technically robust, buildable operation.
• Environmental Baseline Studies
Ongoing baseline data collection, including hydrology, hydrogeology, geochemistry, and biological studies, to support permitting and environmental assessment. requirements.
• Permitting Advancement
Progression of federal and state permitting pathways, including early engagement with regulatory agencies and advancement of key permits required for construction and operations.
• Integrated Development Strategy
Continued evaluation of development scenarios, including integration with Borealis’ existing ADR facility, with the objective of optimizing capital efficiency and accelerating a potential path to production.
The Sandman Gold Project is a conventional open-pit, heap-leach gold project located in Humboldt County, Nevada, approximately 12 miles northwest of Winnemucca. The project hosts four known deposits-North Hill, Silica Ridge, Southeast Pediment, and Abel Knoll-and benefits from proximity to infrastructure and Borealis’ existing operations.
Borealis Mining is a gold mining and exploration company focused on the advancement of its Nevada-based assets, including ongoing mining and production activities at the Borealis Gold Mine and the development of its Sandman Gold Project. The Borealis Gold Mine is a fully permitted mine site, equipped with active heap leach pads, an ADR facility, and all necessary infrastructure to support a heap leach gold mining operation. Borealis is led by a strong board and management team, many of whom have founded, managed, and sold highly successful mining and exploration companies.
