Azimut and SOQUEM Report Excellent Lithium Recoveries and Grades for Metallurgical Test Samples, Galin?e Property, Quebec
LONGUEIL, Quebec, Oct. 17, 2024 (GLOBE NEWSWIRE) -- Azimut Exploration Inc. (“Azimut” or the “Company”) (TSXV: AZM) is pleased to report excellent preliminary metallurgical test results for three (3) representative samples of spodumene-bearing pegmatite from the Galinée Property (the “Property”) in the Eeyou Istchee James Bay region of Quebec, Canada. The Property is a joint venture project between Azimut and SOQUEM Inc., with Azimut acting as the operator.
The test program conducted by SGS Canada Inc. included chemical and mineralogical characterization and metallurgical testing. The objective was to obtain baseline recovery data for a Dense Media Separation (DMS) and magnetic separation flowsheet.
HIGHLIGHTS
- The test program demonstrates excellent lithium recovery through combined DMS and magnetic separation for the three composites (Comp 1 to 3). Lithium recoveries for the three samples are 68%, 79% and 86%, respectively, with spodumene concentrates grading 6.93% Li2O for Comp 1 and 7.10% Li2O for Comp 2 and 3.
- The production of high-grade spodumene concentrates (over 6.90% Li2O) in the 2.95 sink fraction by Heavy Liquid Separation for all samples significantly exceeds the chemical-grade quality required for hydrometallurgical processing.
Testwork Summary
SGS Canada Inc. conducted the tests in their Quebec City laboratory using three representative composite drill core samples of spodumene-bearing pegmatite. The Li2O composition in the material is 1.16%, 2.07%, and 4.52% for Comp 1, Comp 2, and Comp 3, respectively.
Each composite was stage-crushed to P100 passing 9.5 mm, blended, and submitted for chemical and mineralogical analysis. The remaining material from each composite was screened to 850 µm and riffled into charges for metallurgical testwork.
Head Characterization
The program's primary objective was to characterize the composite samples, with a particular emphasis on lithium mineral characterization. This included (see Table 1 below):
- Head analysis;
- Mineralogical analysis;
- Identification of key impurities; and
- Mineralogical analysis on Comp 2 using Tescan Integrated Mineral Analyzer (TIMA-X).
These steps are crucial for developing the metallurgical process, as they significantly influence the operating conditions and approach.
Head Analysis: Representative 75-micron pulverized samples were submitted for an ICP scan analysis. The three samples (Comp 1, Comp 2 and Comp 3) were found to contain silica (69.2% to 80.8%), Al2O3 (12.7% to 21.7%), Fe2O3 (0.86% to 1.93%) and Li2O (1.16% to 4.52%).
Mineralogical Analysis: Quartz, spodumene, albite/plagioclase and elbaite are the main mineralogical phases. XRD analysis revealed that Comp 3 had the highest spodumene content at 56.2%. Hornblende was low in Comp 1 (2.8%) and absent in both Comp 2 and Comp 3.
Detailed Mineralogical Analyses (TIMA-X) performed on Comp 2 indicate excellent spodumene liberation reaching 97.8%. Impurities such as quartz and feldspar also showed high levels of liberation, exceeding 95%.

Metallurgical Testing
Bulk Density Tests: Average density measurements were conducted on five core samples for each composite. The results showed average densities of 2.78, 2.79, and 2.82 g/cm3 for composites 1, 2, and 3, respectively.
Heavy Liquid Separation (HLS) and Magnetic Separation: DMS concentration tests coupled with magnetic separation of the DMS concentrate produced excellent results for all three composite samples.
- A single step of magnetic separation performed at 10,000 Gauss effectively removed the amphibole present in the DMS concentrate for the three composites tested, particularly for Comp 1.
- At a particle size of 9.50 mm, HLS produced high-grade spodumene concentrates (over 6.90% Li2O) in the 2.95 sink fraction for all samples, meeting the chemical grade quality required for hydrometallurgical processing. Lithium recoveries were excellent, at 68%, 79% and 86% for Comp 1, Comp 2 and Comp 3, respectively.
- The concentrates are notably distinguished by their very low impurity levels, with Fe2O3 contents below 1.2% and Cr2O3 contents below 0.01%.
- For Comp 1, magnetic separation was necessary due to the presence of hornblende. Two tests were conducted using the 2.70 and 2.95 sink fractions. In the test performed with the 2.70 sink fraction, the Li₂O concentrate reached a grade of 5.51%, with a lithium recovery of 82.1%. For the 2.95 sink fraction, the Li₂O concentrate reached a grade of 6.93% but with a lower lithium recovery of 68%.
- For Comp 2 and Comp 3, which contain very little amphibole, a simple DMS separation at a density of 2.70, even without a magnetic separation step, could yield Li2O concentrates with purities of 5.99% and 6.76%, with recoveries of 89% and 91%, respectively. This is exceptional and demonstrates the excellent liberation and purity of the lithium-bearing phases of the Galinée mineralized zone.

About the Galinée Property
Galinée (649 claims, 335 km2) is a 50/50 joint venture project between Azimut and SOQUEM. The 36-kilometre-long property lies about 50 kilometres north-northwest of the Renard diamond mine (Stornoway Diamonds (Canada) Inc.) and 60 kilometres south of the Trans-Taiga Road, an all-season regional highway. The region is widely considered an emerging lithium district.
The winter 2023 and spring 2024 drilling program yielded wide intervals of high-grade mineralization in the northernmost part of the Property, notably including (see press release of June 19, 2024):
| 1.62% Li2O over 158.0 m | Hole GAL24-025 | ||
| 2.48% Li2O over 72.7 m | Hole GAL23-001 | ||
| 2.68% Li2O over 54.6 m | Hole GAL24-020 | ||
| 2.13% Li2O over 44.1 m | Hole GAL23-009 | ||
| 1.66% Li2O over 40.4 m | Hole GAL24-018 | ||
| 2.53% Li2O over 25.0 m | Hole GAL24-022 | ||
| 2.02% Li2O over 32.2 m | Hole GAL24-023 | ||
| 1.71% Li2O over 37.0 m | Hole GAL23-011 |
In addition, the summer 2024 program further underscored the project’s strong exploration potential. Extensive lithium targets with a cumulative length of about 18 kilometres have been identified based on systematic till sampling and prospecting. One of the most promising areas, returning up to 2.85% Li₂O in boulders, lies within a 10-kilometre zone in the northwestern part of the Property (see press release of October 10, 2024).
