Borealis Completes Second Gold Pour of 2024 and Lists on Frankfurt Stock Exchange

Vancouver, October 3, 2024 - Borealis Mining Company Ltd. (TSXV: BOGO) (FSE: L4B0) (the "Company" or "Borealis") is pleased to announce that it has completed its second gold pour of 2024 at its on-site ADR facility. This was achieved through the stripping of the Company's 10 carbon columns loaded from residual leaching with a highly dilute cyanide solution. This was the last of the residual leaching from the past year with subsequent pours to be derived from previously un-leached ore.

The second pour resulted in doré bars weighing a total of ~1,625 troy ounces containing 14.116% Au and 9.954% Ag, as determined by an independent assay of a pin sample, for approximately 229 troy ounces of gold and 162 troy ounces of silver. Borealis has begun introducing 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 doré from residual leaching. Please see Figure 1 for a photo of the doré bars from the recent pour.

Kelly Malcolm, CEO of Borealis, comments "Borealis continues to generate meaningful revenue through residual leaching of our existing permitted heap leach pads. We have begun treating the balance of our leach pad with fresh cyanide and expect to increase the frequency and gold content of our pours. With gold prices at all-time highs, our internal engineering and geology teams are hard at work with outside consultants to develop a mine restart plan at our fully permitted and fully built Borealis Mine in Nevada. I'm also excited about our new listing on the Frankfurt Stock Exchange, which coupled with several investor awareness programs, which will allow European investors easier access to Borealis common shares and broaden our investment audience."

The Company is also pleased to announce that it has recently listed its common shares on the Frankfurt Stock Exchange under the symbol L4B0.

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.
