Brunswick Exploration Finds New Large Spodumene-Bearing Pegmatite at

Anatacau Main

MONTREAL, July 13, 2023 -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or the “Company”) is

pleased to announce the discovery of a significant lithium pegmatite outcrop, measuring at least 100m long by 15m large, at

the Anatacau Main Project, located in the Eeyou Istchee-James Bay region of Quebec. The outcrop is within a larger cluster of

pegmatite dykes all of which contain high grade lithium mineralization.

Mr. Killian Charles, President and CEO of BRW, comments: “This exciting discovery demonstrates the clear potential of the

Anatacau Main Property which has never been systematically explored for lithium. Both the Anatacau Main and West Projects

remain very prospective for additional pegmatite discoveries. As exploration remains restricted due to forest fire and alongside

the recent discovery of the substantial spodumene-bearing boulder field at Mirage, BRW is now preparing a major drilling

campaign in Q3 across several assets.”

The Anais Spodumene-Bearing Pegmatite Showing

This discovery is located 22km east of BRW’s Anatacau West and Allkem’s James Bay Project along a large-scale E-W

deformation corridor which is host to the known lithium-bearing pegmatite dykes in the region. This structure runs through both

the Anatacau West and Anatacau Main properties over a total of 15.5 km (see Figure 1), all of which has never been explored

for lithium.

The showing consists of several parallel pegmatite dykes with visible spodumene mineralization. The largest dyke found to

date is exposed over a 15m wide by 100m long outcrop (see Figure 2). The mineralization varies between 5% and 50%

spodumene throughout the pegmatite, with quartz, feldspars and accessory muscovite. Spodumene crystals are light grey and

up to 20cm long (see Figure 3). BRW believes the pegmatite dykes are structurally controlled, dip steeply towards the north-

west with gentle folding and stacking.

To date, BRW has collected over 19 surface grab samples across the Anais showing all of which returned high grades values

ranging from 1.2 to 3.8% Li 2O. The majority of the samples graded above 2% Li 2O, among which the highest grades (>3%

Li2O) are found within the Main dyke, in massive spodumene-rich bands. Note that the described samples are selected

samples and thus the values reported above are not representative of the grade of mineralized zones.

BRW will pursue exploration work on its Anatacau West and Main Project once conditions are deemed safe. In the interim,

BRW will immediately apply for necessary permits to support an Autumn 2023 drilling campaign .

About the Anatacau Project

The Anatacau Main and the Anatacau West Projects are under option from Osisko GP, a subsidiary of Osisko Development

whereby BRW can earn a 90% interest in the projects. For further details, please refer to the November 28 2022 NR.

Quality Assurance / Quality Control

Samples are shipped to ALS Canada Ltd.’s preparation facility in Val-d’Or. Pulps are analyzed at the ALS Canada Ltd. facility

in Vancouver. All samples are analyzed by sodium peroxide fusion with ICP-AES/MS finish. Reported drill intersections use a

lower analytical cut off value of 0.1% Li2O.
