Azimut Further Defines Extensive High-Grade Lithium Pegmatite Field at Wabamisk East, James Bay Region, QuebecInitial core drilling phase cuts multiple spodumene-rich pegmatites LONGUEUIL, Quebec, Dec. 23, 2025 (GLOBE NEWSWIRE) -- Azimut Exploration Inc. (“Azimut” or the “Company”) (TSXV: AZM) (OTCQX: AZMTF) is pleased to announce additional significant exploration progress on the Wabamisk East Property (the “Property”) in the Eeyou Istchee James Bay region of Quebec. The 2025 field program has significantly enhanced the lithium potential of the Property by further defining a high-grade, multi-kilometre-scale spodumene pegmatite field. Wabamisk East, a 100%-owned Property, is regarded by Azimut as offering excellent exploration potential. At least 138 distinct spodumene-bearing outcrops have been identified, with 340 channel and grab samples, returning grades higher than 0.5% Li2O, with an average grade of 1.94% Li2O (see details below). Since the last reported results (see press release of October 9, 2025i), work conducted on the Property comprises: Extensive mechanical stripping;Collection of 280 channel samples; andInitial diamond drilling (5 holes, 615 m) to test surface targets confirmed the down-dip extension of the mineralized outcrops. This work phase has been funded by Rio Tinto Exploration Canada Inc. (“Rio Tinto”), with Azimut acting as the operator. As a result in changes in corporate strategies, Rio Tinto has indicated its intent to terminate its Option to Joint Venture Agreement on the Corvet, Kaanaayaa and Wabamisk East properties on December 31, 2025 (see press release of July 24, 2025ii). Azimut is concurrently advancing two other discoveries on the adjacent Wabamisk Property: the Fortin Antimony-Gold Zone and the Rosa Gold Zone (see press releases dated October 23, 2025iii and November 18, 2025iv). HIGHLIGHTS (see Figures 1 to 6, Table 1, Photos 1 and 2) 205 of the 1-metre-long channel samples collected this field season returned grades higher than 0.5% Li2O, yielding an average grade of 1.66% Li2O: 50 samples with grades from 0.5% to 1.0% Li2O;95 samples with grades from 1.0% to 2.0% Li2O; and60 samples with grades higher than 2.0% Li2O, up to a maximum of 5.63% Li2O Salient channel composite results include: Prospect 1.68% Li2O over 8.0 m Lithos North 1 1.68% Li2O over 7.0 m including 2.46% Li2O over 4.0 m Lithos North 1 1.57% Li2O over 10.0 m Lithos North 1 1.90% Li2O over 11.0 m Lithos North 2 1.72% Li2O over 8.0 m Lithos North 2 1.58% Li2O over 8.0 m Lithos North 2 2.25% Li2O over 5.6 m Lithos South 1.97% Li2O over 7.0 m Lithos South 1.70% Li2O over 4.0 m Lithos South 2.53% Li2O over 7.0 m including 4.02% Li2O over 3.0 m Lithos South – Jumbo 2.12% Li2O over 6.0 m including 2.86% Li2O over 4.0 m Lithos South – Jumbo 2.33% Li2O over 3.0 m Benny 1.42% Li2O over 6.85 m Whale 1.37% Li2O over 4.0 m Whale 1.19% Li2O over 8.0 m Whale Of the 493 samples (162 grabs, 331 channels) collected since 2024, 340 returned grades higher than 0.5% Li2O for an average grade of 1.94% Li2O: 75 samples with grades from 0.5% to 1.0% Li2O;138 samples with grades from 1.0% to 2.0% Li2O; and127 samples with grades higher than 2.0% Li2O, up to a maximum of 7.42% Li2O Grab samples are selective by nature, unlikely to represent average grades, and may not represent true underlying mineralization. Five (5) diamond drill holes (totalling 615 m) have tested three outcropping targets: Lithos North 1, Pierrot and Lithos South. The Company considers this to be a limited initial drill testing phase. Numerous high-grade outcropping targets are drill-ready, and a more substantial follow-up phase is warranted for 2026. Significant spodumene-bearing intervals are as follows (visual observations, downhole lengths, assays pending): Hole WL25-01:One 37.55-metre-thick coarse-grained pegmatite interval with 20 to 30% spodumene from 41.0 m to 78.55 m. This interval includes a 3.75-metre section of amphibolite. Hole WL25-02:Three coarse-grained spodumene pegmatite intervals (7.74 m, 11.75 m, and 24.30 m thick) from 11.7 m to 76.65 m. Amphibolite intercalations are 10.45 and 11.25 metres thick. Spodumene content ranges from 35 to 40%. Hole WL25-03:Four coarse-grained spodumene pegmatite intervals (6.45 m, 3.37m, 0.95 m, and 6.1 m thick) from 43.5 m to 114.1 m. Amphibolite intercalations are 33.8, 2.5 and 16.75 metres thick. Spodumene content generally ranges from 15 to 30%. Hole WL25-04:Five spodumene pegmatite intervals (15.65 m, 4.4 m, 1.95 m, 4.35 m and 1.2 m) from 20.15 m to 154.3 m. Amphibolite intercalations are 67.7, 12.1, 7.9 and 18.9 metres thick. Spodumene content is variable, generally ranging from 10 to 15%. Hole WL25-05:One 5.45-metre interval of coarse-grained pegmatite with 15% spodumene from 49.65 m to 55.1 m. The lithium content of the spodumene mineralization can only be accurately determined by assay analysis. The true widths of the drill intervals are undetermined at this stage.
