Brunswick Exploration Announces Update at Mirage Project, Quebec
BRUNSWICK EXPLORATION ANNOUNCES UPDATE
AT MIRAGE PROJECT, QUEBEC
Montreal, August 21, 2023 – Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW”
or the “Company”) is pleased to announce that, since the restart of exploration work at the Mirage
Project, located in the Eeyou Istchee- James Bay region of Quebec, field crews have successfully
extended the length of the spodumene -bearing pegmatite boulder field and discovered several
spodumene-bearing pegmatite outcrops. The previously announced boulder field (see June 14, 2023
press release) now extends over 3.0 kilometres in a northeast direction and well- mineralized
pegmatite outcrops have been observed along a 2.7 kilometre-long trend further to the northeast. Both
the extent of the outcrops and boulder train remain open in all directions.
Highlights:
• The spodumene boulder dispersion train is very well defined and now extends for 3.0 km in
NE-SW direction (See Figure 1);
• The spodumene boulder dispersion t rain leads directly to several spodumene-bearing
pegmatite outcrops that are spread over an additional 2.7 km along the same NE-SW trend,
suggesting the geological strike is sub- parallel to glacial dispersion in this area. I n total, the
trend of boulders and outcrops covers over 5.5 kilometres of strike and remains open.
• To date, five significant spodumene-bearing pegmatite dykes have been identified with
apparent widths of 25 to 80 metres. The strike length of these dykes is unknown, and field
measurements with magnetic data suggest structural complexity and possible variable strike
directions to the dykes. Additionally, several thinner mineralized dykes have been identified in
the area;
• Another 13 kilometres of up-ice prospecting and geological mapping remains to be completed
with several more reported pegmatite outcrops (Quebec government SIGEOM data base) to
be examined, none of which have been previously evaluated for spodumene content.
Mr. Killian Charles, President and CEO of BRW, commented: “Today’s announcement is an important
milestone for Brunswick Exploration as the rapid discovery of several spodumene-bearing dykes in
outcrops and a leng thy mineralized boulder trend highlights the excellent potential for a hard-rock
lithium deposit. We expect to receive drill permits imminently and will begin a minimum 4,000 metres
drill campaign in September. Furthermore, there remains multiple highly prospective areas across the
Mirage Project which will be explored shortly.”
Mirage Project Overview
Following the initial discovery of multiple plurimetric spodumene- bearing pegmatite boulders (see
press release dated June 14, 2023), Brunswick Exploration focused its efforts in the SW portion of the
Project. This initial prospecting campaign identified a total of 9 mineralized outcrop clusters with the
largest spodumene-bearing cluster measuring approximately 80 metres wide by 100 metres long; all
clusters remain open along strike (Figure 1) . Most observable dykes are oriented in a SW -NE
directions following a major structural trend that runs along the Project area in a similar SW-NE glacial
direction, although some dykes show variable strike directions . In total, the trend of boulders and
outcrops covers over 5.5 kilometres of strike and remains open in all directions (Figure 1).
The mineralized pegmatitic dykes identified to date are predominantly hosted by meta-basalts and
amphibolite, and consequently the mineralized boulder and outcrop area will be covered by airborne
LiDAR and magnetic surveys in the next three weeks to hopefully outline the unexposed strike extent
of the mineralized dykes.

Lithium mineralization identified in outcrops is similar to the boulders observed to the southwest ,
consisting of well-defined, large, light grey spodumene crystals with mineralization varying between 5
and 50% of the pegmatite. Some of the outcrops have spectacular spodumene mineralization with
crystals reaching a maximum length of 1 metre and, concurrently, widths in excess of 30 centimeters
(Figures 2 and 3).

lithium pegmatite field, examining a spodumene-rich outcrop.
The rest of the Project area remains unexplored and there are several other pegmatite outcrops that
have been noted by government geologists in previous surveys but have not been field checked for
spodumene mineralization. About 13 kilometres of favorable geology up-ice from the current
discoveries remains untested.
Next steps at Mirage will focus on continued pr ospecting, airborne surveys and the initiation of a
drilling program. The Company is targeting a minimum of 4,000 metres of drilling based on available
information starting in September. Prior to the start of drilling, BRW will complete detailed LiDAR and
a high-resolution airborne magnetic survey to further define extent of pegmatite dykes and drill targets.
