The Montreal-based explorer Brunswick Exploration Inc. announced a substantive expansion of its Anatacau Main property in the Eeyou-Istchee James Bay region of Quebec. In a press release dated 19/02/2026, the company detailed the identification of seven new unverified spodumene targets and the staking of additional claims immediately west of Anatacau Main. These findings were generated through detailed compilation of historical data, satellite imagery and field-ready target definition ahead of an ongoing drill program.
Management emphasized that the targets sit approximately 22 kilometers east and along strike of a recognized regional lithium-bearing structural corridor that hosts Rio Tinto’s Galaxy Project and Brunswick’s own Anatacau West holdings. According to CEO Killian Charles, these additions materially increase the property’s near-term exploration potential and will guide a focused prospecting campaign once field conditions permit.
The newly mapped targets are organized into three priority clusters: Area A (Anais discovery surroundings), Area B (recently staked western extensions) and Area C (the Pontax trend). Each cluster exhibits compelling characteristics—visible pegmatite densities, size of outcrops and geochemical indicators—that justify follow-up work including ground prospecting and additional drilling.

Anais discovery targets (Area A)
Between two and five kilometers south of the current Anais drill site, Brunswick identified three unverified spodumene showings during its compilation. Satellite mapping revealed in excess of 200 pegmatite outcrops in this sector, with the largest measured at roughly 500 by 200 meters. These concentrations expand the immediate halo around the Anais discovery and provide multiple proximal targets for trenching and sampling once logistics allow.
Newly staked western targets (Area B)
Contiguous to and directly west of Anatacau Main, Brunswick completed staking that secures an additional three unverified spodumene occurrences and about 150 pegmatite outcrops. The most prominent visible outcrop in this block is approximately 800 by 100 meters. The company notes a possibility that southern features in Area A and the showings in Area B may define a secondary trend parallel to the principal corridor—an observation that could expand prospective structural interpretations.
Pontax trend and geochemical indicators
The Pontax trend (Area C) is described as an emergent NE–SW regional corridor that stretches more than 20 kilometers across Anatacau’s southern flank. Within this corridor, Brunswick has identified over 90 pegmatite outcrops and catalogued more than 13 highly fractionated pegmatites displaying favourable geochemistry. In particular, the reported K/Rb ratios fall below 30 and are reported as low as 14, a signature often associated with advanced fractionation in lithium-enriched systems.
The largest visible outcrop in the Pontax sector measures about 200 by 50 meters. These targets neighbor an existing potential spodumene occurrence on Brunswick tenure and align along the same structural trend that hosts third-party projects to the southwest, including Cygnus Metals’ and Li-FT Power’s Pontax projects.
Technical review, next steps and corporate context
All technical content in Brunswick’s announcement was reviewed and approved by Mr. Francois Goulet, Manager Quebec, who is a Professional Geologist registered in Quebec and serves as the company’s qualified person for the release. The company indicated that following completion of the current drill campaign at Anais, it will initiate a targeted prospecting program to rapidly evaluate and ground-truth the newly defined targets as soon as field access conditions are suitable.
Brunswick also positioned Anatacau alongside its broader portfolio, which includes the flagship Mirage project. Mirage underpins one of the company’s most significant assets, a previously reported inferred mineral resource of 52.2 Mt grading 1.08% Li2O. North American and international grassroots assets in Brunswick’s portfolio support its strategy to advance multiple opportunities concurrent with regional exploration.
Implications for exploration and investment
From an exploration standpoint, the combination of numerous visible pegmatites, sizeable outcrops and low K/Rb ratios creates a robust target list that justifies rapid follow-up sampling and drilling. For stakeholders evaluating Brunswick, the news signals an active pipeline of near-term exploration catalysts: ongoing drilling at Anais, imminent prospecting across seven new targets, and a larger regional structural setting that has already attracted major players.
Brunswick’s release dated 19/02/2026 serves as the formal disclosure of these targets. Investors and analysts monitoring the company’s progress should expect updates as ground programs and drilling results are reported.
