Brunswick Exploration Closes Final Tranche of Non-Brokered Private Placement for Total Gross Proceeds of $5,445,000

MONTREAL, March 23, 2026 - Brunswick Exploration Inc. (TSX-V: BRW; OTCQB: BRWXF; FRANKFURT:1XQ) ("BRW" or the "Corporation") is pleased to announce that it has issued an additional 5,000,000 units of the Corporation (each, a "Unit"), at a price of $0.25 per Unit, for additional gross proceeds of $1,250,000, pursuant to its previously announced non-brokered private placement.

In the aggregate, the Corporation issued 20,780,000 Units and raised gross proceeds in the amount of $5,445,000 under the offering (the "Offering").

Killian Charles, President an CEO of BRW, commented: "With the completion of this financing, we will be accelerating our international plans as our compilation work has identified several highly prospective jurisdictions that have seen limited to no prior lithium exploration. As we continue to expand our reach, we also remain steadfast in growing our high priority projects in Quebec. To that effect, I look forward to releasing first results from our Anatacau drilling campaign very shortly. Alongside our Mirage project, I strongly believe BRW has one of the most exciting exploration portfolios in Quebec."

Each Unit consists of one common share of the Corporation (a "Unit Share") and one half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant entitles the holder thereof to purchase one common share of the Corporation (a "Warrant Share") at a price of $0.35 per Warrant Share for a period of 36 months.

The Corporation intends to use the net proceeds of the Offering for exploration activities at the Corporation's properties in Canada, Saudi Arabia and Greenland, as well as for general corporate purposes and working capital.

In connection with the Offering, the Corporation paid finder's fees to arm's length third parties in an aggregate amount of $278,200 and issued 490,000 non-transferable finder warrants ("Finder Warrants"). Each Finder Warrant is exercisable to purchase one common share of the Corporation (a "Finder Warrant Share") at a price of $0.25 per Finder Warrant Share for a period of 24 months. The Finder Warrants are subject to a restriction period of four month and one day pursuant to applicable Canadian securities laws.

The Offering was completed pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 - Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 - Exemptions from Certain Conditions of the Listed Issuer Financing Exemption (the "Listed Issuer Financing Exemption").
