BRUNSWICK EXPLORATION ANNOUNCES 2025 EXPLORATION PLANS FOR GREENLAND AND STAKES ADDITIONAL GROUND NEAR PAAMIUT

Brunswick Exploration Inc. has made plans for a 2025 summer exploration program in Greenland, as well as a mineral licence expansion of the Paamiut project.

Killian Charles, president and chief executive officer of Brunswick Exploration, commented: "Following strong metallurgical results and the start of drilling at the Mirage project in Quebec, we are delighted to announce assay results from the Ivisaartoq discovery near Nuuk, the capital of Greenland. The assays confirm the presence of spodumene throughout the discovery dike and demonstrates that it is part of an evolved trend, which will require significant additional work to fully realize its potential. This highly prospective trend remains underexplored with dozens of pegmatites yet to be visited.

"We are also very pleased and thankful for the Greenlandic government's efforts in locating the original document that identifies the location of an unconfirmed historical spodumene showing, first identified in 1972 and wholly located within our Paamiut project. In light of this new showing, we have significantly increased our licences in the Paamiut region.

"Brunswick Exploration is now one of the largest mineral licence holders in Greenland and is the only company exploring for lithium, leveraging its first-mover advantage in the country. With a strong mining regime alongside prospective geology and excellent outcrop exposure, we believe 2025 will be a key year for lithium in Greenland as we launch one of the largest regional exploration initiatives in the country."

2025 Greenland summer program

Brunswick Exploration will launch an aggressive regional-scale prospecting and mapping initiative on its extensive Greenland portfolio beginning in mid-June, using four crews and two helicopters for six weeks. In June, the team will focus on detailed mapping and sampling around the Ivisaartoq discovery and surrounding areas while the other will focus on the expanded Nuuk and Paamiut licences. Starting in July, the team will focus on follow-up prospecting at the Nuuk and Paamiut projects based on results from June while the other team will focus on the recently acquired Disko Bay and Uummannaq projects (see news release of Nov. 7, 2024). Results from the first six weeks will be used to plan advanced exploration programs in August and September, 2025, across the entire portfolio.

Ivisaartoq discovery results

The company has received grab sample assays from its discovery dike producing up to 2.40 per cent Li2O. The lithium-bearing dike is within an evolved trend measuring roughly three kilometres by 1.5 kilometres and remains open in all directions with low magnesium/lithium and potassium/rubidium ratios. To reiterate, the 2024 first-pass prospecting focused on rapidly producing portable XRF K/Rb analysis on potassium feldspar crystals while the 2025 second pass will focus on detailed mapping and further sampling in the anomalous area. As these pegmatites are kilometric in scale, they will require systematic sampling and detailed mapping.

For whole rock analysis, the Mg/Li ratio is much more indicative of a favourable lithium-bearing outcrop or trend than field-generated feldspar K/Rb ratios. Mg/Li ratios in whole rock samples of less than 10 indicate an evolved pegmatite, and less than 1 indicates the potential to be spodumene bearing with the latest assays outlining over 20 samples with ratios below one. In addition, hundreds of interpreted and mapped pegmatite outcrops in the Ivisaartoq belt were not visited during the limited 2024 field season.

Historical Paamiut lithium reference uncovered

As referenced in the press release dated Oct. 30, 2024, a 10-kilometre greenstone belt hosted an unconfirmed and geographically uncertain historical database spodumene showing with a reported assay of 1.23 per cent Li2O from the early 1970s. After numerous discussions with the Geological Survey of Denmark and Greenland (GEUS), an accurate location for the showing was ascertained to be roughly four kilometres from the previous incorrect location in the database. The area contains several dozen pegmatites which have been never been prospected. During the 2024 first pass, the company sampled an evolved pegmatite (based on K/Rb) roughly one kilometre from the revised location of the historical lithium assay. The company is eager to visit this area in 2025 and has expanded its Paamiut landholdings accordingly.

Paamiut staking

The new licences are located roughly 90 to 130 kilometres from the coastal town of Paamiut, which is approximately 260 km south of the capital Nuuk. Paamiut is home to roughly 1,300 people. The new licence area lies within the North Atlantic craton specifically within the Bjornesund tectonic block. This block is composed of tonalitic and granodioritic orthogneiss, as well as favourable Mesoarchean metavolcanic amphibolite belts. The North Atlantic craton extends westward into northern Labrador, Canada, and eastward into eastern Greenland.

Multiple metavolcanic amphibolite belts were acquired that are up to roughly 1.5 kilometres in width and 15 kilometres in strike length. The new claims have numerous mapped and interpreted pegmatite targets, including nine that are between 500 and 900 metres in strike length, for a total new licence area of 20,785 hectares. Licence applications have been submitted and are awaiting government final approval.
