Brunswick Exploration Launches 5,000 Metre Drill Program At Mirage Project, Quebec

Brunswick Exploration Launches 5,000 Metre Drill Program At Mirage Project,

Quebec

MONTREAL, Sept. 07, 2023 -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or the “Company”) is

pleased to announce that a minimum 5,000 metres drill program has begun at the Mirage Project, located in the Eeyou

Istchee-James Bay region of Quebec. The Phase One, 26-hole program, will test continuity and widths of the six widest

spodumene-bearing pegmatite dykes that have been discovered to date on the property (see August 21, 2023 press release)

over a total cumulative strike length of 2,500 metres. Furthermore, the Company wishes to announce that further prospecting

has identified additional spodumene-bearing outcrops approximately 4.5 kilometres northeast of the center of the previously

defined dyke field. The trend of mineralized dykes now extends for about 6 kilometres with the boulder field extending for an

additional 2.7 kilometres to the southwest. Both the extent of the outcrops and boulder train remain open in all directions.

Mr. Killian Charles, President and CEO of BRW, commented: “I am greatly encouraged by the rapid expansion of the

spodumene-bearing dyke field at Mirage. This new discovery confirms the up-ice potential and there remains substantial more

prospecting to be done on the property in the coming weeks. Drilling will start by testing the six most significant dykes

identified to date, and we expect that the next few months will be extremely exciting for BRW shareholders.”

Lithium-bearing outcrops now extend across six kilometres

Several new outcrops have been identified in the existing dyke field exhibiting similar characteristics to known dykes in

respect to mineralogy, spodumene concentration and large crystal sizes. The main dyke field now covers an area measuring

approximately 2,700 by 850 metres. Nearly all the outcrops mapped to date remain open in all directions with few observed

contacts with the basalt host rock.

The additional discovery of a new dyke three kilometres to the northeast reinforces the lithium prospectivity of Mirage. This

dyke has an apparent strike length of at least 175 meters. The width of the dyke remains unknown at this time as the

exposure is limited. In addition, other spodumene-mineralized pegmatite boulders have been found nearly 2 kilometres west of

the main boulder train suggesting additional sources exist further to the west. In total, lithium mineralization on the Mirage

Project has been observed over a total distance of 8.7 kilometres, inclusive of the boulder field. The latter will be the subject of

detailed prospecting in an effort to located new spodumene-bearing outcrops further to the southwest of the main dyke field.
