The Sandman Project

advanced exploration & development gold project in Nevada
with near-term production potential

This acquisition marks a major milestone for Borealis, significantly enhancing our future production profile with the addition of the high-quality Sandman gold project. By leveraging the synergies between Borealis and Sandman, we are not only strengthening our Nevada asset base but also optimizing capital efficiency and accelerating our path to meaningful gold production. With a robust portfolio of advanced and exploration stage projects, Borealis is well positioned to deliver long-term value for our shareholders in one of the world’s most prolific jurisdictions. We welcome the new shareholders to the Borealis journey and look forward to advancing Sandman towards a feasibility study and eventual gold production.
