BRUNSWICK EXPLORATION DISCOVERS ADDITIONAL SPODUMENE PEGMATITES IN PAAMIUT, GREENLAND

Brunswick Exploration Inc. has confirmed a historical spodumene pegmatite and discovered a second one at its Paamiut project in Greenland. Brunswick Exploration now has two projects with confirmed lithium showings in Greenland and is the only company actively looking for lithium in Greenland.

Killian Charles, president and chief executive officer of Brunswick Exploration, commented: "Following the expansive new discoveries at our Nuuk project, this new Paamiut discovery is a great complement to our unique Greenland portfolio. These additional lithium-bearing pegmatites highlight the team's ability to identify and make new grassroots discoveries. We are evaluating next steps at Paamiut and have already begun planning for a maiden drill program at Nuuk. All of BRW's Greenland discoveries are in proximity to fjord infrastructure, and, with ties to Europe, we are very excited to continue our efforts in Greenland. Combined with an active drill program at its Anatacau Main project and a forthcoming resource estimate at the Mirage project, both in Quebec, BRW is among the most aggressive lithium exploration globally."

Paamiut confirmation and discovery

Brunswick Exploration has confirmed a historical spodumene-bearing pegmatite and discovered a second dike at the company's Paamiut project. The discoveries are approximately 26 kilometres from Paamiut, a coastal community located about 260 kilometres south of Nuuk in western Greenland. The dikes are hosted within a large shear zone and are found within a roughly 10-kilometre-by-two-kilometre greenstone belt (see news release dated Feb. 18, 2025).

The spodumene pegmatites are roughly three to six metres wide and 40 to 60 metres long and are spaced approximately 10 metres apart from one another. Lithium mineralization is primarily spodumene, which varies from 5 to 30 per cent, containing pale green crystals ranging from one to 10 centimetres in size. The company believes that there is potential to host additional spodumene pegmatites within the greenstone belt. Spodumene mineralization was confirmed by both pXRF (portable X-ray fluorescence) and LIBS (laser-induced breakdown spectroscopy) units. Grab samples were sent for analysis to ALS in Dublin, Ireland, and thin-section samples will be prepared for further mineralogical studies.

Greenland portfolio update

During the summer campaign, the team completed first-pass prospecting on all western Greenland licences while advancing both Nuuk and Paamiut. Due to continued exploration successes at Nuuk and Paamiut, additional time was not available to conduct first-pass prospecting at the Hinksland licence located in eastern Greenland. However, the team is already planning the next opportune time to evaluate that licence. Additional spodumene discoveries were not identified outside of the Nuuk and Paamiut areas at this time.

Corporate update

BRW also wishes to announce that Mathieu Savard has resigned as a director of the company in order to focus all of his time and attention on his role as chief executive officer and president of Vior Inc. On behalf of the board and shareholders, Brunswick Exploration would like to thank Mr. Savard for his contributions to the company over the years.
