What is the estimated contained spodumene resource after the recent discovery and how does it compare to the previous estimate?

Estimated contained spodumene resource

The new pegmatite strike that Brunswick has mapped adds roughly 1.3 million t Li₂O of spodumene‑bearing material to the Ivisaartoq lithium pegmatite field. Prior to the August 2025 announcement the field was reported to host about 0.9 million t Li₂O of contained spodumene. In other words, the recent discovery expands the resource by ≈44 %, taking the total in‑ground grade‑tonnage from just under 1 Mt Li₂O to ≈2.2 Mt Li₂O (≈2.5 Mt Li₂O containing spodumene mineralisation, depending on conversion assumptions).

Trading and market implications

• Fundamentals: A near‑doubling of the Greenland spodumene resource positions Brunswick as a potentially significant upstream supplier for the fast‑growing EV battery market. With global spodumene demand projected to rise 30‑40 % YoY through 2030, the expanded resource could justify a re‑rating of the company’s valuation multiples (e.g., P/NAV moving from ~0.8× to >1.2×) and attract strategic investors or off‑take partners.
• Technical outlook: The stock has been trading in a tight range around the 0.85 CAD level for the past 4 weeks, with the August 12 news likely to trigger a breakout. Assuming a modest 15 % upside on the news‑driven rally (to ~1.00 CAD) and a 10 % downside risk (to ~0.77 CAD), a 50 %/50 % risk‑reward position could be set with a stop just below the recent low (0.78 CAD) and a target at the 1.00 CAD resistance.
• Actionable insight: Given the sizable resource uplift and the bullish supply‑side narrative for lithium, the market is likely to price in the upside over the next 2‑3 months. A short‑term long position (or a call‑option play) on BRW, sized to risk 2 % of portfolio capital, aligns with the expected catalyst‑driven price appreciation while keeping exposure limited if the market digests the news more slowly.
