BRW Brunswick Exploration Inc

Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; FRANKFURT:1XQ; “BRW” or the “Company”) is pleased to announce its plans for the 2025 summer exploration program in Greenland as well as a mineral license expansion of the Paamiut project.

Mr. Killian Charles, President and CEO of BRW, 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 dyke 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 licenses in the Paamiut region.

Brunswick Exploration is now one of the largest mineral license 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

BRW will launch an aggressive regional-scale prospecting and mapping initiative on its extensive Greenland portfolio beginning in mid-June, using 4 crews and 2 helicopters for six weeks. In June, one 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 licenses. Starting in July, one team will focus on follow-up prosecting 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 November 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 dyke producing up to 2.40 % Li2O (Figure 1). The lithium-bearing dyke is within an evolved trend measuring roughly 3 kilometers by 1.5 kilometers and remains open in all directions with low Mg/Li and K/Rb 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 favorable Li bearing outcrop or trend than field-generated feldspar K/Rb ratios. Mg/Li ratios in whole rock samples of <10 indicates an evolved pegmatite and <1 indicates the potential to be spodumene bearing with the latest assays outlining over 20 samples with ratios below 1. 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 October 30th, 2024, a 10-kilometer greenstone belt hosted an unconfirmed and geographically uncertain historical database spodumene showing with a reported assay of 1.23% 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 4 kilometers 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 1 kilometer from the revised location of the historical lithium assay (Figure 2). The company is eager to visit this area in 2025 and has expanded its Paamiut land holdings accordingly.

Paamiut Staking

The new licenses are located roughly 90 to 130 km from the coastal town of Paamiut, which is approximately 260 km south of the capital Nuuk (Figure 3). Paamiut is home to roughly 1,300 people. The new license 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 westwards into northern Labrador, Canada and eastwards into eastern Greenland. 

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