Brunswick Exploration Inc. (TSX-V: BRW, OTCQB:
BRWXF; “
BRW” or the “
Company”) is
pleased to announce inaugural drilling results from the Mirage
Lithium Project, located in the Eeyou Istchee-James Bay region of
Quebec. The initial 5,000 meters drilling campaign outlined four
major spodumene-bearing pegmatite dykes where significant intervals
of continuous lithium mineralization were drilled. All pegmatite
dykes drilled to date start at surface, are open in all directions,
and are located within an area of approximately two by two
kilometers. Several other outcropping dykes and promising targets
have yet to be drilled, including the sizeable boulder train to the
southwest of the dyke swarm.
Highlights include:
- Bonanza grades of 2.57%
over 25.8 meters in drill hole MR-23-02, including
14.2 meters at 3.08% Li2O at a
vertical depth of 28 meters from Dyke MR-1 in the North Zone.
- Thick intercept of 50.6 m
at 1.06% Li2O in drill hole MR-23-07 from Dyke MR-3 in the
Central Zone at a shallow vertical depth of 22 meters.
- Another bonanza
intercept in drill hole MR-23-14: 16.2 m at 2.75%
Li2O including 9.5 meters at 3.30% Li2O
at a vertical depth of 40 meters in Dyke MR-4 from the South
Zone.
- To date, spodumene-bearing
pegmatite dykes have been traced by drilling over a
combined strike extent of at least 1,500 meters and remain
open in all directions.
- Only 60% of the pegmatite outcrops
have been drilled, presenting further drill targets which will be
tested in winter 2024.
- Assays are pending for a further 23
drill holes completed during the fall 2023 program.
Mr. Killian Charles, President and CEO of BRW,
commented: “We are rapidly starting to outline a major discovery in
the Eeyou Istchee-James Bay. This true grassroot discovery was
first identified in August with drilling beginning less than six
weeks later. Already several large mineralized dykes have been
intercepted in shallow drilling with significant bonanza style
grade reported in this first set of assays. Importantly, these
pegmatite dykes remain open in all directions. With the recently
completed $5.7M financing, we are well positioned to substantially
expand the discovery at Mirage with a winter 2024 drill
program.”
Mr. Robert Wares, Founder and Executive
Chairman, also commented: “I am very pleased with these initial
drill results. Mirage already demonstrates potential for a large
lithium-rich dyke field with some of the highest-grade intercepts
reported in Eeyou Istchee-James Bay. Furthermore, I believe the
distribution of the first four mineralized dykes at Mirage does not
explain the three-kilometer long trend of rich spodumene-bearing
boulders that occurs to the southwest. With more outcropping
spodumene-bearing dykes located another 3 kilometers to the
northeast, we have considerable exploration work and drilling to do
to unlock the full potential of this promising property”.

Holes 13 and 15 through 36 are pending
Mirage Drilling Campaign
Overview
The aim of the 2023 drilling campaign was to
test at shallow depths (less than 150 meters vertical depth) the
pegmatite dykes mapped from surface to determine their geometry and
orientation. Thirty-six (36) diamond drill holes were completed
(see Figure 1) for a total of 5,090 meters drilled to date.
Thirty-three (33) of the 36 holes drilled during the 2023 campaign
intercepted mineralized pegmatites.
The mineralized pegmatite dykes discovered at
the Mirage Project are distributed along three major trends in a
NE-SW axis, the North, Central and South Zones, within a two by two
kilometers area (see Figure 1). The mineralized dykes are massive,
very coarse-grained, with a mineralogy consisting of quartz, white
feldspar, minor muscovite and black tourmaline, light grey
spodumene and traces of beryl. The consistently decimetric
spodumene mineralization often reaches up to 50% of the modal
mineral content.
This inaugural drilling campaign has
successfully extended the mineralized pegmatites over a combined
distance of 1.5 km and demonstrates excellent continuity with
several high-grade zones intersected to date. All pegmatite dykes
remain open in all directions. In addition, several other
outcropping spodumene-bearing pegmatites remain to be
drill-tested.

Mirage Project and Drill Holes Completed to Date
Central Zone
The MR-3 pegmatite dyke intercepted in the
Central Zone show significant apparent thicknesses of up to
50.6 meters at 1.06% Li2O
(MR-23-07) with a moderate dip at around 50 degrees towards the
south with true thickness estimated at 95% in all reported holes
(see Figure 2). The main dyke in the Central Zone is oriented NE
and reaches the surface where it can be traced continuously for
more than 400 meters with continuous thickness in excess of 40
meters and grade averaging approximately 1.00%. To date, the main
dyke in the Central Zone is defined by six drill holes (MR-23-05 to
07 and MR-23-09 to 12) and remains open in all directions.
A second, unmapped dyke (MR-3A) was identified
in drill hole MR-23-08, marking the first blind discovery of a
pegmatite dyke at Mirage. The hole only partially intercepted the
margin of the dyke and is not representative of the grade or width
of the MR-3A Dyke. Drill hole MR-23-35 targeted this new dyke and
assays are still pending.

North Zone
North Zone
Four shallow drill holes were carried out in the
North Zone (MR-23-01 to MR-23-04). All holes intercepted two
spodumene bearing pegmatite dykes, MR-1 and MR-2. Two holes
MR-23-01 and MR-23-02 returned bonanza grade interval: 24.5
m at 2.18% Li2O and
25.8 m at 2.57%
Li2O respectfully. The
MR-1 dyke likely dips to the north, and the true thickness is
estimated to be 90% of the core length (see Figure 3). Both dykes
remain open in all directions. Furthermore, another three
spodumene-pegmatite outcrops located up to 1 km further east remain
undrilled in the North Zone..
South Zone
Preliminary results from the South Zone, all
from pegmatite dyke MR-4, also show significant near-surface
bonanza grade mineralization. The dyke has been continuously traced
by drilling over more than 750 meters with a moderate dip of 45
degrees to the south (see Figure 4). Only one drill hole from the
dyke in the South Zone is reported in this news release; MR-23-14
returned 16.2 m at 2.75%
Li2O. Similar
bonanza mineralization has been observed along the entire length of
the dyke and remains open in all directions.

QAQC
All drill core samples were collected under the
supervision of BRW employees and contractors. The drill core was
transported by helicopter and by truck from the drill platform to
the core logging facility in Val-d’Or. Each core was then logged,
photographed, tagged, and split by diamond saw before being
sampled. All pegmatite intervals were sampled at approximately 1m
intervals to ensure representativity, and ¼ core splits were
inserted regularly as duplicates. Samples were bagged, and blanks
and certified reference materials for lithium were inserted at
regular intervals. Groups of samples were placed in larger bags,
sealed with numbered tags, in order to maintain a chain of custody.
The sample bags were transported from BRW contractor facility to
the ALS laboratory in Val-d’Or. All sample preparation and
analytical work was performed by ALS. Samples were crushed in order
for 70% of the material to pass through a 2mm screen (method
CRU-31), a riffle split was made of a 1,000g sub-sample (SPL-21),
and the split sample pulverized (PUL-31) to obtain more than 85% of
the material inferior to 75µm. A 0.2g sub-sample of the pulverized
fraction was dissolved in a sodium peroxide solution, prior to
lithium analysis by ICP-AES according to the ALS method ME-ICP82b.
All results passed the QA/QC screening at the lab and all inserted
standard and blanks returned results that were within acceptable
limits. All reported drill intersections are calculated on the
basis of a lower cutoff grade of 0.10% Li2O, with maximum internal
dilution of 1 metre. Host basalts adjacent to the dykes grade up to
0.3% Li2O but were excluded from the reported intersections.
