Brunswick Exploration Inc. has intersected a 202.45-metre-wide spodumene-bearing pegmatite interval containing an estimated 25% spodumene at the Anatacau Main Project in the Eeyou Istchee James Bay region of Quebec.

Drill hole AN-26-15 targeted the Anais Main dyke via a 130-metre down-dip step-out, extending the vertical depth of the dyke to 300 metres. Previous drilling had defined the Anais Main dyke to a vertical depth of 190 metres. The latest intercept represents the single largest pegmatitic intercept drilled by Brunswick Exploration across its portfolio.

The hole encountered several separate spodumene-bearing pegmatite intervals with widths of up to 21.3 metres, containing between 20% and 35% spodumene. The work also extends the Anais Main dyke footprint to the west, which is now traced over 650 by 350 metres. All assay results for drill hole AN-26-15 are currently pending.

While it is atypical for us to release mineralized intervals without assays, we believe the size of this major interval and its implication for the Anatacau Main project is highly material to Brunswick Exploration shareholders as it instantly elevates the Anais dyke to being one of the most exciting discoveries globally. Importantly, this discovery remains open in all directions. We are actively drilling at Anatacau and look forward to expanding this discovery. More details from future work programs at Anatacau will be shared shortly.

Of note, we will be also releasing exciting assays from Mirage in the coming weeks. It is once more an affirmation of our strong exploration focus as we continue to expand our portfolio. Brunswick Exploration has now made two sizeable discoveries, Mirage and Anatacau, and sees more opportunity in Greenland, the Middle East and further abroad.
