Brunswick unearths thick, shallow lithium in Quebec

TSX-V-listed Brunswick Exploration (TSX-V:BRW) has drilled thick intercepts of lithium from surface in its recently completed winter campaign at the Mirage Project in Quebec.

The 35-hole program, which was targeting the Central Zone, returned what Brunswick says is the “best interval to date” of 1.59% lithium over 58.1m starting at surface.

That hit extends the flat dipping MR-6 dyke a further 80m to the south, with the target remaining open in all directions, according to Brunswick. 

Other top intercepts featured 31.6m @ 1.71% lithium, including 14m @ 2.32% lithium from 60m vertical depth, 300m east of the MR-6 dyke. 

Brunswick says this provides evidence of ‘significant dyke stacking’.

The Mirage Project is located in the Eeyou Istchee-James Bay region of Quebec, a proven lithium mining province, around 40km south from the Trans-Taiga Road.

Rio Tinto (ASX:RIO) and Newmont are among the majors active in the region, with Rio last year revealing its plans to explore for lithium via its subsidiary Rio Tinto Exploration Canada. 

The project sits 34km northeast of Winsome Resources’ (ASX:WR1) Adina Project, where in early March drilling extended the Main Zone with results including 12.6m @ 1.92% Li2O from 50.4m, as previously reported

Brunswick President and CEO Killian Charles says the MR-6 dyke has proven to be an extremely prospective exploration target with significant potential given it remains open in all directions. 

“On the basis of current and expected results from our winter campaign, we have immediately started preparations and planning for a summer drilling campaign at Mirage. 

Combined with our extensive grassroot exploration across Canada and Greenland, the forthcoming summer promises to be milestone-rich for Brunswick Exploration shareholders.”

Other near-surface intercepts include 18.4m @ 1.03% lithium from 11m and 12m @ 0.93% lithium from hole MR-24-60, where four major dykes have already been intercepted and remain open in every direction.

Brunswick says a spodumene-bearing pegmatite boulder field extends over 3km in a northeast direction and several dozen well-mineralised pegmatite outcrops have been observed along a 2.5km-long trend further to the northeast.

Further drill results will be released from the MR-6 target and the company expects it will be a core part of future drilling campaigns at Mirage.
