CEO.CA Chairman's Briefing

Vancouver, British Columbia--(Newsfile Corp. - August 28, 2024) - Borealis Mining Company Limited (TSXV: BOGO) (the "Company" or "Borealis") is pleased to announce that it has completed its first gold pour of 2024 at its on-site ADR facility. This was achieved through stripping of 2.5 of the Company's 10 carbon columns, which were loaded from residual leaching with a highly dilute cyanide solution. The first pour resulted in doré bars weighing ~651 troy ounces containing 21.968 % Au and 20.169 % Ag, as determined by an independent assay of a pin sample, for approximately 143 troy ounces of gold and 131 troy ounces of silver. Please see Figure 1 for a picture of the pour.

In the near term, Borealis intends to strip the remaining 7.5 carbon columns and then introduce fresh cyanide to a section of the leach pad which has previously not been leached, which should result in a higher gold percentage doré compared to the material generated through residual leaching. The Company also recently submitted a number of super sacks of spent carbon fines to Just Refiners (USA) Inc. of Reno, NV, which contained 76.504 troy ounces of gold and 305.012 troy ounces of silver.

Kelly Malcolm, CEO of Borealis, comments, "We are very pleased to announce our first gold pour of the year, which will now increase in frequency as we strip our remaining carbon columns and start to put fresh cyanide on our leach pad. We are also in the process of seeking contractors to crush our ~330,000 ton stockpile of ore, which should also generate meaningful gold production for the Company and our shareholders. Borealis is unique to many of our peers in the junior exploration sector, in that we are revenue generating and control a fully permitted mine and ADR facility. I'm also glad to announce Lisanna Lewis as our new Chief Financial Officer, who has decades of experience with Nevada mining operations."

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. The property possesses high grade expansion potential with excellent historical drilling results, along with a number of untested regional targets.
