Brunswick Exploration doubles lithium corridor at Nuuk

MONTREAL, June 24, 2026 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc.  ( TSX-V: BRW , OTCQB: BRWXF ; FRANKFURT:1XQ ; “ BRW ” or the “ Company ”) is pleased to announce that it has extended the spodumene-bearing corridor at its Nuuk Lithium project near Nuuk, Greenland through the confirmation of an additional spodumene bearing pegmatite over three kilometres from the initial discovery zone. This expansion nearly doubles the scale and width of the mineralized system. Mr. Killian Charles, President and CEO of BRW, commented: “The growing scale of the Nuuk Lithium project highlights the lithium potential in Greenland.

Next steps, including drilling, are currently being evaluated in conjunction with the return of drilling at Mirage and an anticipated Anatacau fall drilling campaign. In addition, our team will embark on a maiden prospecting program on our East Greenland Portfolio starting mid-July. As lithium markets and fundamentals gain momentum, we believe that Greenland remains one of the most exciting and underexplored jurisdictions with significant critical mineral endowment globally.

With first-mover advantage, Brunswick Exploration is the only company exploring for lithium in the country.” Ivisaartoq Pegmatite Field Expanded at Nuuk Lithium The newly discovered spodumene-bearing pegmatite significantly expands the area affected by late-stage, highly evolved lithium-bearing fluids. This corridor now measures approximately four kilometers by one kilometer. As a comparable, the Company’s Mirage project has a corridor of lithium-bearing pegmatites measuring approximately six by three kilometers.

The new LCT pegmatite had returned anomalously low K/Rb ratios, however, spodumene was not immediately identified in the field and a sample was collected for further analysis (see Figure 1). Subsequently, the sample was sent for thin section analysis where the presence of spodumene was rapidly confirmed. Brunswick Exploration awaits results from another potential target which could also expand the corridor of lithium mineralization.

To date, a total of nine spodumene-bearing pegmatites have been discovered in the Ivisaartoq field, measuring up to 400 meters in length and 40 meters in width, with up to 50% visual spodumene (See releases dated October 30, 2024 and August 12, 2025). Hinks, Clavering and Hudson Campaign Brunswick Exploration will complete helicopter-supported prospecting and mapping throughout the East Greenland portfolio starting in mid-July which includes the Hinks, Clavering and Hudson licences (See releases dated March 13, 2025 and February 3, 2026). The entire eastern coast of Greenland has never been prospected for lithium.

Figure 1: Expanded Nuuk Lithium Corridor QAQC Thin section samples were collected in the field by the BRW team and Dr. Donnelly Archibald of St. Francis Xavier (StFX) University, located in Antigonish, Nova Scotia. Rock samples were shipped from Nuuk to Dr. Archibald who cut them into 25mm by 46mm slabs that were shipped to Precision Petrographics in Vancouver, British Columbia for the preparation of polished thin sections. The prepared sections were returned to Dr. Archibald who analyzed them using an Olympus BX53 petrographic microscope at StFX University.

Spodumene was initially identified in thin section at StFX then confirmed using electron probe microanalysis (EPMA) at Memorial University in St. John’s, Newfoundland.
