Brunswick Exploration Acquires More Highly Prospective Lithium Targets in Greenland

MONTREAL, Feb. 03, 2026 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW; OTCQB: BRWXF; Frankfurt: 1XQ) (“BRW” or the “Company”) is pleased to announce the staking of new high-priority lithium targets in Eastern Greenland, known as Clavering and Hudson Land. With these additions to its global lithium portfolio, BRW reinforces its position as one of the most active exploration companies in Greenland and remains the only company in the country exploring for lithium. BRW discovered and controls the only two known Greenlandic lithium discoveries.

Mr. Killian Charles, President and CEO of BRW, commented: “Greenland is one of the most underexplored and geologically prospective jurisdictions globally, presenting a unique opportunity for Brunswick Exploration. As lithium market fundamentals continue to strengthen, we believe now is the optimal time to enhance the Company’s position on a global scale, underpinned by our Mirage project where we recently announced an Inferred Resource of 52.2Mt grading 1.08% Li2O, as well as our burgeoning Anatacau project where drilling is expected to begin shortly. These newly identified targets host some of the most compelling geochemical signatures we have encountered in Greenland, supported by highly favourable geology. While we continue advancing plans for a future drill program at our Nuuk Lithium Project expected in late Q3, we anticipate conducting prospecting activities at both Clavering and Hudson Land and our Hinks Land licence this summer.”

Clavering and Hudson Land Licence

The newly staked licence comprises five blocks and is located approximately 360 kilometres north of the community of Ittoqqortoormiit along the east coast of Greenland and roughly 200 kilometres from Greenland Resources’ Malmbjerg Open Pit Molybdenum Project, which was granted an exploitation permit in 2025. This permitting milestone underscores Greenland’s clear commitment and long-term vision to advance the development of new critical mineral projects (Figure 1).

The licence area hosts dozens of mapped and interpreted pegmatite outcrops, some extending to kilometric scale, covering a total licence area of 13,862 hectares. The broader licence and surrounding region include two-mica granites, gneiss, amphibolite, marble, metasedimentary units, and ultramafic rocks, providing a robust geological framework for lithium-cesium-tantalum (“LCT”) pegmatite systems.

One area within the new claims package is particularly noteworthy due to its exceptionally high rubidium (“Rb”) values identified in historical regional stream-sediment surveys. Elevated Rb values can be an important indicator of highly evolved pegmatite systems which host lithium mineralization. More than 15,600 stream-sediment samples have been collected and analyzed across Greenland by Greenlandic and Danish geological surveys. Of these, only 28 samples rank within the 99.998th percentile for Rb concentration and, notably, 25 of those samples occur within a 15-kilometre-diameter area encompassed by the new licence. These elevated Rb values are accompanied by numerous highly anomalous cesium values and several elevated tantalum values, further strengthening the lithium prospectivity of the area. It is important to note that lithium was not analyzed in the historical surveys.

Licence applications have been formally submitted and are currently awaiting final government approval.

2026 Greenland Exploration Program

Brunswick Exploration plans to visit the Clavering and Hudson Land area in Q3, in conjunction with field activities at its Hinks Land Project. This helicopter-supported program is expected to last approximately two weeks. BRW will then initiate a small drill program at its Nuuk Lithium project to test the spodumene bearing pegmatites identified during the 2025 field season. The drill campaign is expected to start in late Q3 and more information will be released in due course.

The Company would like to thank Xploration Services Greenland A/S for their continued support with licence applications and logistical planning for the 2026 field season.
