Drill Results

BRUNSWICK EXPLORATION INTERCEPTS 26.5 METERS GRADING 1.51% LI2O

IN INITIAL DRILL RESULTS FROM ANATACAU WEST

Montreal, May 24, 2023 – Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or

the “Company”) is pleased t o announce that it has received a first set of results from its recently

completed drilling campaign at the Anatacau West project , located in the Eeyou Istchee-James Bay

region of Quebec. The initial results presented today are from twelve holes with another six pending.

Final assays for the remaining holes are expected in the coming weeks.

Drill result highlights

o 26.5 metres at 1.51% Li2O in drill hole AW-23-01;

o 9.9 metres at 1.03% Li2O in drill hole AW-23-10;

o 10.1 metres at 1.06% Li2O, including 4.9 m at 1.63% Li2O and 12.6 metres at 1.12% Li2O

in drill hole AW-23-14.

Mr. Killian Charles, President and CEO of BRW, commented: “With the start of our pan- Canadian

grassroot lithium exploration campaign, one of the largest lithium exploration initiatives in North

America, we are excited to receive assays confirming the presence of high- grade, near-surface and

thick lithium-bearing pegmatites from our inaugural drilling campaign at Anatacau West . Our drilling

tested the pegmatites to a shallow depth and their remains substantial opportunities for more growth.

With minimal regional prospecting for lithium, we look forward to continue ex panding the lithium

potential both at the Anatacau West and the Anatacau Main project over the coming weeks and

months.”

Anatacau West Drilling Campaign Overview

Following drilling completed to date, BRW believes it has intercepted at least two continuous, distinct

spodumene-bearing pegmatites. All of the pegmatites are oriented north-northeast, are closely spaced

in an on- echelon pattern and dip steeply towards the west. The pegmatites are hosted in

metasedimentary rocks in an east -west deformation corridor similar to Allkem’s neighboring James

Bay Lithium Deposit.

Drilling has initially focused on near surface mineralization with the pegmatites only being drill tested

to a maximum vertical depth of 137 meters. They remain open at depth. Furthermore, potential exists

for repetition of new pegmatites further to the south and to the east.

Lithium mineralization consists predominantly of spodumene with minor lepidolit e. Spodumene

crystals are generally well -formed, decimetric in scale (up to 10cm) and have a white to pale grey

color. Importantly, grade is strongly correlated with visually identified spodumene percentage in core

allowing BRW to rapidly ascertain the lithium potential of mineralized intercepts in exploration drilling.

Next Steps

Starting next week, our exploration campaign in Quebec will begin with regional, helicopter-supported

prospecting at the Anatacau West and Anatacau Main projects from the nearby Wabamisk camp.

Already, BRW has identified more spodumene-bearing pegmatites at Anatacau Main, located 22 km

east from Anatacau West. These pegmatites have been minimally prospected and will be a priority

target. BRW expects to conduct follow -up on stripping and/or drilling on several targets across both

projects once it has completed an initial wave of prospecting.

Concurrent to work at Anatacau West and Anatacau Main, BRW will also be operating a camp at the

PLEX project to the north and a smaller fly-camp at the Mirage project located further east from PLEX.

The Company’s portfolio in the entire Eeyou Istchee-James Bay region includes over 250 untested S-

type pegmatites measuring a minimum strike length of 500 meters (for more information on the BRW’s

regional prospecting plan for the Eeyou Istchee-James Bay region, see NR dated May 11 2023).

Further analysis revealed that mineralization in AW -23-03 was composed of cookeite, a phyllosilicate lithium

mineral and not spodumene.
