MONTREAL, Oct. 30, 2024 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ; “BRW” or the “Company”) is extremely pleased to announce that it has discovered a lithium-bearing pegmatite containing spodumene within the company’s Nuuk License, located roughly 90 kilometers north-east of Nuuk, the capital of Greenland (Figure 1). The newly discovered pegmatite outcrop is open in all directions and is part of a significant evolved pegmatite field measuring over 20 kilometers long known as the Ivisaartoq Field, marking the first confirmed lithium discovery in the country.

Mr. Killian Charles, President and CEO of BRW, commented: “We are delighted to announce the first hard rock lithium discovery in Greenland. This discovery was made near the end of our field season after spending limited time in the country and leveraged Brunswick’s strong exploration expertise. Prior to our discovery at Ivisaartoq, there were no confirmed showings in Greenland and it demonstrates the strong potential for additional discoveries across the entire country which has never been previously explored for lithium. Importantly, it represents a significant opportunity for the Company as we remain first movers for lithium exploration in Greenland.”

“Outcrop exposure and proximity to tidal water at Ivisaartoq and across our Greenland portfolio is exceptional. The country is one of the best mining and exploration jurisdictions globally with strong community and government support. We are thrilled to make the first of, hopefully, many more discoveries in Greenland alongside our flagship Mirage project with the goal of identifying lithium sources for both the North American and European supply chains.”

Nuuk License - Ivisaartoq Discovery

The Ivisaartoq pegmatite field is part of the larger Nuuk License, hosted within the Ivisaartoq Greenstone Belt. The trend is located roughly 90 kilometers northeast of Nuuk, the capital of Greenland, on the Western central coast of the country. This area of Greenland is part of the North Atlantic Craton that extends into Nunavut and Labrador. The belt is Mesoarchean in age and contains amphibolites, metasediments, ultramafics, genesis, gabbros, granites and pegmatites (Figure 2).

The spodumene-bearing dyke was traced and interpreted to be roughly 400 meters with an exposed width of roughly 5 meters containing up to 50% centimetric green and white spodumene (Figure 3). The spodumene was confirmed by UV light as well as LIBS (“Laser Induced breakdown spectroscopy”). The dyke is open in all directions and is part of a larger evolved dyke field containing several dozen pegmatites that are metric to kilometric in scale which remain to be prospected. The Ivisaartoq belt is divided in two distinct trends: the South trend which is roughly three kilometers wide by approximately 20 kilometers long and the North trend which is roughly 1.5 kilometers wide by 20 kilometers long. Work in 2024 was largely limited to the South trend where the discovery dyke is located due to time constraints. However, both the North and South trend require much more prospecting in 2025 as the discovery was made late in the campaign and hundreds of mapped and interpreted pegmatite outcrops remain untested.
