Borealis Drills 4.06 g/t Gold over 21.3 Metres

Within 2.25 g/t Gold over 99.1 Metres at

Historical Graben Deposit in Nevada

Toronto, Ontario--(Newsfile Corp. - November 13, 2024) - Borealis Mining Company Limited (TSXV:

BOGO) (FSE: L4B0) (the "

Company

" or "

Borealis

") is pleased to announce the assay results from

several drillholes at the Graben target completed as part of its ongoing ~3,500 metre drill program at its

Borealis Gold Project in the Walker Lane trend of Nevada.

Drilling at the Graben historical gold deposit has demonstrated large widths of highly consistent gold

mineralization within an extremely silicified and sulfidized body.

Highlights include:

DHBM011 which returned 2.25 g/t Au over 99.1 m including 4.06 g/t Au over 21.3 m;

DHBM013 which returned 2.11 g/t Au over 36.6 m including 8.24 g/t Au over 4.6 m, and 2.06 g/t Au

over 27.4 m further downhole; and

DHBM008 which returned 1.58 g/t Au over 45.7 m.

Kelly Malcolm, CEO of Borealis, comments "We're very pleased to see large widths of strong grades of

gold at the Graben historical gold deposit. These intervals confirm and expand upon known historical

results which indicate a large body of near-surface gold mineralization. We intend to return to the Graben

area early in 2025 to test for additional high-grade ore shoots and attempt to grow the system, especially

to the north where it remains wide open. The Graben zone is particularly intriguing in that Borealis is

already permitted to conduct a 55,000 tonne underground bulk sample, which was proposed to be

completed through a ramp in the adjacent Freedom Flats pit.

Borealis is also busy on many other fronts, including continued oxide-focused RC drilling on the western

portion of the Borealis project, geological mapping and sampling, residual leaching of our existing

permitted heap leach pad, and planning and preparing for crushing our 330 thousand tonne stockpile of

oxide mineralization from prior operations and resumption of mining within our fully permitted mine site."

The results in this release are largely related to the Graben historical gold deposit (documented in the

current Borealis NI 43-101 Technical Status Report, filed on SEDAR+). The Graben historical gold

deposit is classified as a high-sulfidation epithermal system. It occurs within Miocene andesite volcanics

below ~130 metres of alluvium and post-mineral sedimentary cover rocks. Gold is closely associated

with pyrite and marcasite, multi-phase hydrothermal breccias, intense silica alteration, and quartz

veining. High-grade pods occur within the large blanket of lower grade mineralization. The Graben

system is situated to the west and northwest of the Freedom Flats pit (

Figure 1

), and may in fact be part

of the same mineralizing system as evident by historic drilling. A number of metallurgical studies have

been conducted on Graben material throughout its history, as detailed in Borealis' current technical

report (filed on SEDAR+), which indicates the material is amenable to flotation and/or oxidation.

Qualified Person and QA&QC

The scientific and technical content of this news release was reviewed, verified, and approved by Kelly

Malcolm, P.Geo., Chief Executive Officer of the Company, and a Qualified Person as defined by

Canadian Securities Administrators' National Instrument 43-101 - Standards of Disclosure for Mineral

Projects.

The quality assurance and quality control protocols in place at Borealis include insertion of blank or

standard samples every 10 samples on average, in addition to the regular insertion of blank duplicate,

and standard samples by the analytical laboratory during the assay process. The assay results

presented herein are derived from both diamond drill core and RC drill chips. For diamond drill core,

geologists mark out samples for geotechnicians to saw in half, from which one half is retained at the

Borealis mine site and the other half is submitted for assay. For RC drilling, geologists supervise riffle

splitting of RC return at the drill site. Samples were submitted to both ALS Global's Reno, NV laboratory

and Paragon Geochemical's Sparks, NV laboratory. At ALS, samples were treated with a 30 gram fire

assay with an AA finish, along with a four-acid multi-element analysis (MS-MS61). At Paragon, samples

were treated either with a 30 gram fire assay with an AA finish or a 300-500 gram PhotonAssay for Au,

and four-acid multi-element analysis (48MA-MS).

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.

About Borealis

Borealis is a gold mining and exploration company focused on exploration and resumption of production

of the Borealis Mine in Nevada. The Borealis Mine is a fully permitted minesite, 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 751 unpatented mining claims of

approximately 20 acres each totalling approximately 15,020 acres and one unpatented mill site claim of

about five acres located in western Nevada, is highly prospective for additional high-sulfidation gold

mineralization. Borealis is led by a strong board and management team, many of whom have founded,

managed, and sold highly successful mining and exploration companies.
