Borealis Mine 

The Borealis mine property, located close to the town of Hawthorne, NV, is fully permitted and equipped for present mine operations and future expansion, with existing open pits, heap leach pads, modern infrastructure, and a functional ADR facility which produces doré bars. The project has historically produced over 600,000 ounces of gold from an open pit heap leach operation. It is an under-explored property and has not been drilled since 2011, aside from Borealis’ efforts in 2024 and 2025. The property possesses high grade expansion potential with excellent historical drilling results, along with a number of untested regional targets.

The Borealis Project holds existing federal and state permits for mining and processing operations. However, certain permit modifications may be required for expanded production, and the timeline for such approvals is subject to regulatory review. The Company cannot guarantee the timing or success of any permit modifications that may be required for future expansions.

About Borealis

Borealis is a gold mining and exploration company focused on exploration and resumption of production of the Borealis Mine in Nevada and the advancement of its Sandman project also in Nevada. The Borealis 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. In addition to the mine, the property, comprised of 815 unpatented mining claims of approximately 20 acres each totaling approximately 16,300 cres and one unpatented mill site claim of about five acres located in western Nevada, is highly prospective for additional high-sulfidation gold mineralization. The Sandman project, recently acquired through the acquisition of Gold Bull Resources Inc., is an advanced exploration project with a recently completed (2021) NI 43-101 compliant resource and a recent (2023) Preliminary Economic Assessment which indicates compelling economics, particularly in light of the increase in commodity prices since publication of the study. Borealis is led by a strong board and management team, many of whom have founded, managed, and sold highly successful mining and exploration companies.
