Montreal, April 20th, 2023 – Brunswick Exploration Inc. (TSX-V: BRW; “BRW” or the “Company”) is pleased to announce that the Anatacau West maiden drill program has been completed and that drilling has intersected multiple spodumene-bearing pegmatites. The Anatacau West Project is located in the Eeyou Istchee-James Bay region of Quebec near Allkem’s James Bay Lithium Project.
Mr. Killian Charles, President and CEO of BRW, commented: “We are pleased that we have successfully identified significant spodumene mineralization in our maiden drilling campaign. Several lithium pegmatite dykes were intersected that remain open at depth and along strike to the south. While the Anatacau West Project remains poorly explored and merits further work this summer, we remain focused on continuing our ambitious Canada-wide exploration campaign as we seek to delineate new prospective lithium-bearing pegmatites. This phase of drilling at Anatacau West is over and we now look forward to sharing more details on our next drill campaign at the Hearst Project before the end of the month.”
Table 1: Drill Holes with Pegmatite Intersections Greater Than Two Meters
Note: All drill holes are NQ core size and all intervals are core length and presented for all pegmatite intervals greater than 2 metres. True width of intervals is not confirmed. Geological modelling is ongoing; azimuths and dips presented are those ‘planned’ and may vary off collar and downhole; intervals of visible spodumene include minor intervals of non-pegmatite units. Data for drill holes presented herein are based on a combination of preliminary and detailed geological logs and therefore, is considered to be preliminary in nature as there may be variations from the final detailed geological log when completed.
Anatacau West Drill Campaign Overview
A total of 3,712 metres, representing 18 drill holes, was drilled at Anatacau West, targeting extensions of mineralized pegmatites found on Allkem’s neighboring claims. The drilling completed to date has successfully identified several spodumene-bearing pegmatites, two of which have a strike length of over 250 metres. Of the 18 drill holes, 17 drill holes intersected spodumene mineralization. All pegmatite intersections are above 200 metres depth; significant intercepts are listed in Table 1, for which assays are pending.
Following summer prospecting, BRW will evaluate the appropriate next steps at Anatacau West. At this time, no further drilling is planned as the Company wishes to fully evaluate the potential of its extensive portfolio in Quebec across the rest of Canada before proceeding with further drilling.
Following drilling completed to date, BRW believes the pegmatites are oriented north-northeast, are closely spaced in an on-echelon pattern and dip steeply towards the west. The pegmatites are hosted in metasedimentary rocks similar to Allkem’s James Bay Lithium Deposit. Potential exists for repetition of new pegmatites further to the south and to the east.
Lithium mineralization in core was visually identified and consists predominantly of spodumene with minor lepidolite (see Figure 1,2,3). Spodumene crystals are generally well-formed, decimetric in scale (up to 10cm) and have a white to grey color (see Figure 3 for close-up picture of core and spodumene crystals).
The drill program initially consisted of a set of two fences, each spaced approximately 150 meters from each other. Five drill holes were completed in each fence (at ~75 to 100 m spacing). Two scissor holes were also drilled to confirm the geometry of the pegmatite dykes. Mineralization and pegmatite widths are their strongest in the middle of each fence reaching up to 32.9m in width with visible mineralization of Spodumene up to 20% (see Table 1 & Figure 4).
Another three holes targeted pegmatites that were identified through satellite imagery approximately 3 kilometres to the east. Strongly altered pegmatites were intercepted in two of the drill holes with traces of spodumene mineralization.
