BRUNSWICK EXPLORATION ANNOUNCES THE DISCOVERY SPODUMENE-BEARING PEGMATITE AT THE ELROND PROJECT

Following the restart of prospecting across its portfolio in the Eeyou-Istchee James Bay region of Quebec, Brunswick Exploration Inc. has uncovered a new, undocumented spodumene-bearing pegmatite at the Elrond project. The spodumene-bearing pegmatite outcrop, known as the Arwen showing, is exposed over a surface area measuring approximately 250 metres by 100 metres, dipping very shallowly to the north. The pegmatite remains open in all directions.

Killian Charles, president and chief executive officer of Brunswick Exploration, commented: "Following the exciting large-scale lithium discovery at Mirage and building on our exploration success at Anatacau with the Anais showing, I am very pleased that our team have made another spodumene discovery in the James Bay, which is quickly becoming one of the prospective hard-rock lithium regions in the world. Both Anais and Arwen will be drill tested in 2024, concurrent to our ongoing drilling campaign at Mirage."

The Arwen discovery

The Arwen outcrop is well mineralized in spodumene throughout the showing, with an apparent higher-grade zone containing up to 30 per cent spodumene, which has a visible extent of approximately 75 metres by 15 metres. The spodumene crystals are well formed and up to 30 centimetres in length with an off-white colour, and were confirmed through LIBS (laser induced breakdown spectroscopy) analysis.

The discovery is part of a larger trend of fractionated pegmatites that include a number of beryl showings. However, no other occurrences of spodumene have been observed to date elsewhere on the Elrond project.

The Elrond project is part of the Mythril option agreement with Midland Exploration Inc., whereby Brunswick Exploration can earn a maximum of 85-per-cent interest in the project. For further details see the press release dated Nov. 10, 2022.

Mirage drilling update

The company began drilling on Sept. 11, at the Mirage project with a single helicopter-supported drill rig. To date, 15 holes have been drilled with current total metreage over 1,000 metres. Significant spodumene-bearing pegmatites have been intersected in 12 holes over widths ranging up to 52 metres (true thickness presently unknown). The first set of assays from the inaugural drill campaign at Mirage are expected in the second-half of October. Brunswick Exploration will continue drilling as long as fall weather permits. Further drill programs for winter 2024 are currently being planned.
