BRUNSWICK EXPLORATION LAUNCHES MULTINATIONAL EXPLORATION CAMPAIGN

Brunswick Exploration Inc. has started a helicopter-supported prospecting campaign in Quebec with additional programs in Labrador and Greenland to begin in July and August, 2024, respectively. Brunswick Exploration plans to systematically test hundreds of new and outcropping S-type pegmatite targets across its portfolio.

Killian Charles, president and chief executive officer of Brunswick, commented: "While we continue to focus our efforts into the Mirage project, we are thrilled to start new, ambitious grassroots initiatives throughout Eastern Canada and Greenland. These initiatives are a core pillar of BRW's strategy and, as the lithium industry remains ripe for new discoveries, we will continue to leverage our exploration expertise to rapidly identify new targets and explore in sound jurisdictions."

Overview of prospecting programs

Quebec

A regional helicopter-supported prospecting and mapping program began at the Mirage project, outside the main area of known mineralization. As the 2023 exploration campaign was severely shortened due to forest fires, significant portions of the project remain underexplored. The Mirage project has a total surface area of 21,230 hectares with a potential mineralized corridor of more than 12 kilometres. Already, new pegmatite outcrops with low potassium/rubidium ratios have been identified within this corridor and on strike with the existing dikes drilled in the two previous drill campaigns.

In preparation for the summer drill campaign to be announced in the coming weeks, Brunswick Exploration has decided to expand its assaying methodology at Mirage. Work completed to date indicates that mineralized pegmatites have a broad lithium alteration halo which stretches several dozen metres into the host rock, rapidly enriching in proximity to lithium mineralization. Any anomalous lithium content in the host rock could be indicative of new, buried pegmatites. As such, 10 drill holes, two which have intersected mineralization at the start of the hole (MR-23-27 and MR-23-34) as well as another eight holes which did not intersect pegmatite (holes MR-23-23, 24 and MR-24-37, 42, 63, 68, 70 and 71), have been sent for geochemical analysis (full collar table available on the Brunswick Exploration website) with assays pending. Another two historical holes, previously drilled by Osisko Mining in 2017, will also be sent for assaying.

Furthermore, a targeted till program will be conducted in the three-kilometre boulder train to better define potential drill targets. Results will be incorporated into the forthcoming summer drill campaign which will also target the MR-6 dike and sizable lithium mineralization intersected in the neighbouring MR-24-60 drill hole.

Next, a regional prospecting, till and soil program will be conducted at the Anatacau Main project, also located in the James Bay area. The efforts will focus on the Eastmain-Sorbier Shear zone which hosts Brunswick Exploration's Anatacau West project, the 2023 Anais discovery at Anatacau Main and Arcadium's James Bay project (maiden ore reserve of 37.2 million tonnes at 1.3 per cent lithium oxide). These efforts will lead to a maiden drill program at the Anais discovery at Anatacau Main property in H2 of this year.

At Elrond, a six-hole drill program last winter did not intersect significant mineralization within the spodumene-bearing pegmatite. Assays are pending but are not expected to return economic grades or widths. Brunswick Exploration remains focused on delineating its best assets and eliminating targets that do not meet its stringent requirements. It is currently evaluating the next steps at Elrond.

Finally, in early July, the team will complete a 14-day prospecting and mapping program in the Nunavik region, near the community of Kuujjuak, targeting outcropping S-type pegmatites, one of which is reported to contain lepidolite (purple Li-bearing mica). Importantly, this area hosts over 50 outcropping pegmatites located near tidewater and has seen no previous exploration focused on lithium.

Southeast Labrador

Brunswick Exploration's prospecting team will move to the Port Hope Simpson area of Labrador after it has completed all high-priority prospecting in Quebec. The 10-day helicopter-supported prospecting and mapping program will test multiple evolved S-type pegmatites that contain beryl and tourmaline that have not seen any previous exploration.

Greenland

In late July, the company will start a two-week program near Nuuk, followed by a one-week program in Paamiat. The prospecting and mapping initiative will be based out of communities and will target historical beryl and tourmaline-bearing S-type pegmatites, some having anomalous geochemistry typically associated with lithium-bearing pegmatites. These projects are also located near tide water which would facilitate any ensuing drill program.
