MONTREAL, Nov. 17, 2025 (GLOBE NEWSWIRE) -- Brunswick Exploration Inc. (TSX-V: BRW, OTCQB: BRWXF; “BRW” or the “Company”) is pleased to announce inaugural drilling results from its Anatacau Main Project, located in the Eeyou Istchee-James Bay region of Quebec. All drillholes were centered on the Anais showing and intercepted multiple, large spodumene-bearing pegmatites with rich lithium mineralization. The pegmatites are found along a major deformation corridor, reminiscent of the neighboring Galaxy deposit owned by Rio Tinto located 22 kilometers to the West.
Highlights include:
1.66% Li2O over 47.2 meters in drill hole AN-25-05 within a larger package of continuous lithium mineralization (present within both country rock and pegmatites) of 120.7 meters at1.31% Li2O.- Very high cesium values intercepted in multiple secondary sub-parallel dykes including
1.46% Cs2O over 1 meter and0.8% Cs2O over 1 meter. - This latest discovery is now drill traced over 170 meters of strike length and is open in all directions.
Mr. Killian Charles, President and CEO of BRW, commented: “Today’s exciting results underscores the opportunities across our continuously growing portfolio. We are rapidly starting to define a sizeable lithium system at Anatacau Main which, importantly, remains open in all directions. Furthermore, we are seeing mineralization constrained to the same structural corridor that is found at Rio Tinto’s Galaxy project (54.3Mt M&I at
Between these strong results at Anatacau, a forthcoming maiden resource estimate for Mirage, an inaugural drill campaign in Greenland and further growth opportunities beyond the existing portfolio, Brunswick Exploration is among the most exciting companies in the lithium exploration space.”

Results Interpretation
The largest pegmatite outcrop observed at the Anais showing has now been extended to over 170 meters in strike length and to a maximum depth of 98 meters. It remains open in all direction with an apparent thickness of 47.2 meters (DDH AN-25-05) at its widest point. The main pegmatite dyke is interpreted to be dipping 85 degrees to the West. Several other, well-mineralized stacked pegmatite intervals were also intercepted in all holes, demonstrating the potential for more dyke discoveries in the vicinity of the outcrop (Figure 1). The mineralized dykes discovered at Anatacau straddle the southern side of an interpreted major deformation zone, striking northwest-southeast; a structural control that is reminiscent of the Galaxy deposit (Figure 2). The different pegmatite dykes appear to be oriented North-South to Northeast-Southwest.
The pegmatite dykes show excellent continuity in terms and mineralogy and grade, with several high-grade zones intersected to date (Table 1, Figure 3). The mineralized pegmatite dykes typically exhibit massive to coarse crystals (15+centimeters) with a mineralogy consisting of quartz, white K-feldspar, plagioclase, white spodumene, and minor amounts of muscovite, fine-grained tourmaline, and blue apatite. Spodumene crystals are inclusion-free and are consistently white unlike spodumene mineralization found at the Galaxy deposit and Anatacau West which varies from off-white to greenish. Some pegmatite intervals are under the cut-off of
Host rocks consist of greywacke and amphibolite, locally deformed into schist near the deformation zone where pegmatites seem to propagate well into both units. Holmquistite, a lithium amphibole, is commonly observed in all host rocks at varying concentrations (up to
A geometallurgical study is underway at SGS using DMS (Dense Media Separation) with results expected early in 2026.

Anatacau Drilling Campaign Overview
Six (6) diamond drill holes were completed (see Figure 1 and Table 2) for a total of 750 meters. The holes were spaced by 55 to 100m, and all holes intercepted mineralized pegmatites.
The aim of the 2025 drilling campaign was to test at shallow depths (less than 150 meters vertical depth) the pegmatite dykes mapped at surface on the Anaïs showing. The drilling campaign was performed in HQ size to perform a geometallurgical study, planned according to a grant from the Ministry of Natural Resources and Forests of the Quebec Government.
Brunswick exploration discovered the Anais showing in 2023, which consists of several parallel pegmatite dykes with visible spodumene mineralization. The largest dyke found to date is exposed over a 15 m wide by 100m long outcrop. Several grab samples returned high grade values ranging from1.19 to

All drill core samples were collected under the supervision of BRW employees and contractors. The drill core was transported by helicopter to the logging facility at camp Wabamisk. and by truck from the drill platform to the core logging Each core was then logged, photographed, tagged, and then packed to be shipped to Val-d’Or. Core splitting by diamond saw and sampling was done by BRW contractor at their Val-d’Or facility. All pegmatite intervals were sampled at approximately 1m intervals to ensure representativity, excluding all host rock material. Host rock was also sent for analysis 1m before and after each pegmatite interval. Samples were bagged, and blanks, pulp duplicates and certified reference materials for lithium were inserted at regular intervals. Groups of samples were placed in larger bags, sealed with numbered tags, in order to maintain a chain of custody. The sample bags were transported from BRW contractor facility to the Agat laboratory in Val-d’Or. All sample preparation and analytical work was performed by Agat Laboratories. Samples were crushed in order for
