Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF) is pleased to announce that a minimum 5,000 metres drill program has begun at the Mirage Project, located in the Eeyou Istchee-James Bay region of Quebec. The Phase One, 26-hole program, will test continuity and widths of the six widest spodumene-bearing pegmatite dykes that have been discovered to date on the property (see August 21, 2023 press release) over a total cumulative strike length of 2,500 metres. Furthermore, the Company wishes to announce that further prospecting has identified additional spodumene-bearing outcrops approximately 4.5 kilometres northeast of the center of the previously defined dyke field. The trend of mineralized dykes now extends for about 6 kilometres with the boulder field extending for an additional 2.7 kilometres to the southwest. Both the extent of the outcrops and boulder train remain open in all directions.

Mr. Killian Charles, President and CEO of BRW, commented: “I am greatly encouraged by the rapid expansion of the spodumene-bearing dyke field at Mirage. This new discovery confirms the up-ice potential and there remains substantial more prospecting to be done on the property in the coming weeks. Drilling will start by testing the six most significant dykes identified to date, and we expect that the next few months will be extremely exciting for BRW shareholders.”

Lithium-bearing outcrops now extend across six kilometres

Several new outcrops have been identified in the existing dyke field exhibiting similar characteristics to known dykes in respect to mineralogy, spodumene concentration and large crystal sizes. The main dyke field now covers an area measuring approximately 2,700 by 850 metres. Nearly all the outcrops mapped to date remain open in all directions with few observed contacts with the basalt host rock.

The additional discovery of a new dyke three kilometres to the northeast reinforces the lithium prospectivity of Mirage. This dyke has an apparent strike length of at least 175 meters. The width of the dyke remains unknown at this time as the exposure is limited. In addition, other spodumene-mineralized pegmatite boulders have been found nearly 2 kilometres west of the main boulder train suggesting additional sources exist further to the west. In total, lithium mineralization on the Mirage Project has been observed over a total distance of 8.7 kilometres, inclusive of the boulder field. The latter will be the subject of detailed prospecting in an effort to located new spodumene-bearing outcrops further to the southwest of the main dyke field.
