Brunswick hits a 202-metre pegmatite at Anatacau — no assays yet
A wide spodumene intercept steps the Anais dyke 130 metres deeper. Grades are still visual estimates, and the lab work is pending.
Brunswick Exploration says it drilled through 202.45 metres of spodumene-bearing pegmatite — spodumene is the mineral that carries lithium — in hole AN-26-15 at its Anatacau Main project in Quebec’s James Bay region. That is a genuinely large slab of rock for the district. The company is upfront that it broke its own rule to announce it: the numbers here are visual estimates of roughly 25% spodumene by eye, not lab-confirmed lithium grades. In its own words, releasing an interval without assays is atypical.
Here is why the width still matters. The hole is a stated 130-metre down-dip step-out, drilled at a steep angle so the intercept sits roughly between 135 and 376 metres below surface — and it pushes the Anais dyke to about 300 metres of vertical extent, with the dyke appearing to thicken at depth. The footprint is now traced 650 by 350 metres. That is a real geological signal, backed by an earlier hole pairing and by neighbours: Rio Tinto’s Galaxy lies 20 kilometres away, and a prior Anatacau hole returned 123 metres at 0.72% Li2O. CEO Killian Charles built this company after helping take Integra Gold to its C$590 million sale to Eldorado in 2017; his background is capital markets, not mine-building. The stock rose 5.6% over three months while the lithium benchmark LIT fell 14.5% and base-metals peers dropped 7.4% — a roughly 20-point spread versus the lithium benchmark over the same period.
Now the honest part. There are no assays, so lithium grade is unconfirmed and gram-metres cannot be calculated — width without proven tenor. A table note discloses the 202-metre core may contain up to 25% country rock, so the mineralised width is materially less. True thickness is estimated at about 75% of core length, implying roughly 150 metres true width. Only two holes have been drilled in the Anais sector so far, across about 800 metres, making this a near-isolated result. The cut-off grade is not stated. What to watch: assays from AN-26-15 and the balance of Anatacau holes are promised ‘as quickly as possible,’ Mirage assays in ‘coming weeks,’ and details on future Anatacau work ‘shortly.’ AN-26-16 is drilling now.
