Brunswick Exploration (TSX-V:BRW) has returned 202.45m @ 1.31% lithium oxide (Li₂O) from its Anatacau Main Project in Québec’s Eeyou Istchee James Bay region, Canada, confirming grades within a previously reported pegmatite intersection.
Hole AN-26-15 intersected the Anais dyke from 274.25m, including a ‘higher-grade’ section of 85.75m @ 1.73% Li₂O from 298.4m.
The reported intervals are downhole lengths. Brunswick estimates true thickness at approximately 75% of drilled length and notes the overall interval can contain up to 25% country rock.
CEO Killian Charles says the assays strengthen the company’s assessment of Anais.
“Anais is rapidly improving, not just in width, as the considerable length of the intercept highlights, but also in grade,” Charles says.
“These assay results are extremely encouraging and underscore the potential that exists at Anais.”
The hole also returned separate intervals of 21.5m @ 1.41% Li₂O and 9.2m @ 1.28% Li₂O outside the main dyke.
As previously reported by Mining.com.au, AN-26-15 tested a 130m down-dip step-out, extending Anais to a vertical depth of 300m. The dyke’s footprint was traced over 650m by 350m and remained open in all directions.
Brunswick’s preliminary interpretation suggests the dyke changes from nearly vertical near surface to a shallower 45° dip at depth. Further drilling will test that geometry.
Four holes totalling approximately 1,700m have been completed in the Anais sector, with assays pending from the other three. Drilling continues at Anatacau.
The company also plans metallurgical studies, noting coarse spodumene crystals and low accessory mineral content in the pegmatite.
Brunswick Exploration is a Montréal-based lithium explorer advancing projects in Canada, Greenland, and Saudi Arabia.
