Brunswick Exploration Inc. announces that it has identified the country’s largest spodumene pegmatite trend.
The discovery of multiple new spodumene-bearing pegmatites significantly expands the Ivisaartoq lithium pegmatite field, which was discovered last year on the Nuuk license. This major trend now extends over a strike length of approximately 2 kilometres.
“The discovery of this 2 km by 300 m area of spodumene bearing dykes is a testament to BRW’s systematic and efficient approach,” said Killian Charles, BRW’s President and CEO. “I would like to personally thank the BRW team, Xploration Services Greenland A/S, the Geological Survey of Denmark and Greenland, and the Greenland Mineral Resource Authority for their dedication and support.”
This exploration success reflects the company’s consistent, systematic approach to exploration and Brunswick Exploration is currently designing and evaluating the opportune time to begin a comprehensive drill campaign at Ivisaartoq.
Ivisaartoq Discovery Expansion
BRW has now identified a minimum of eight pegmatite outcrops that occur within a corridor measuring approximately 2000 m long by 300 m wide, which remains open in all directions. This spodumene corridor is within a larger, highly favourable, geochemically anomalous envelope measuring roughly 3 km by 1.5 km. This envelope contains numerous additional, highly fractionated pegmatites. The company believes that there is potential to host additional spodumene pegmatites at surface and at depth within the aforementioned corridor, the larger geochemically anomalous envelope as well as the entire south Ivisaartoq belt, which measures roughly 20 km in strike (see news release October 30, 2024).
The surface expression of the spodumene outcrops range in size from roughly 5 to 400 m in length and 2 to 40 m in width. The lithium mineralisation is predominantly spodumene which varies from sparse to up to 50%, containing white and pale green crystals that range in size from 1 to 40 cm. Other minor lithium bearing minerals include holmquistite in the host rocks, elbaite, as well as lepidolite. The Company is already planning an inaugural drill campaign for Ivisaartoq to test the newly discovered outcrops.
Spodumene mineralisation at the newly discovered outcrops was confirmed by both pXRF and LIBS units. Grab and channel samples are being sent for analysis to ALS in Dublin, Ireland, and thin section samples will be prepared and examined for mineralogical understanding. The size, orientation, and overall grade of the pegmatite outcrops will be better established as the drill campaign progresses.
