Snapshot	Sayona’s Abitibi hub, which includes the North American Lithium (NAL) operation and the nearby Authier Lithium Project, is North America’s largest lithium (spodumene) producer with potential for further expansion. Having restarted operations in early 2023, NAL transitioned from commissioning to full-scale production during FY24 and then focused on optimisation and stabilisation in FY25. Environmental baseline studies and engineering assessments were launched to support a brownfield expansion scenario that could increase annual plant throughput beyond its capacity, with initial scoping indicating the expanded output could be achieved through incremental infrastructure upgrades. On 15 Sep 2025, the outcomes of a Scoping Study for the expansion of the NAL operation were announced, targeting increased annual concentrate production, reduced unit operating costs, and a process plant capacity uplift to 6,500 tpd (+44%).

Summary:

North American Lithium’s pegmatite dykes have been delineated over a strike length of approximately 3,550m and to a vertical depth of approximately 700m. Dykes have variable widths up to 70m. The model comprises 117 mineralised dykes which are generally more than 2m in thickness and open at depth.

The project is located in the region of The Archean Preissac-Lacorne syn- to post-tectonic intrusion that was emplaced in the southern Volcanic Zone of the Abitibi Greenstone Belt of the Superior Province of Québec. The rocks are split between granodiorite, volcanics, gabbro and the mineralised pegmatites dykes that are cross-cutting the granodiorite and the volcanics rocks.

Volcanic rocks on the property are represented by dark green mafic metavolcanics and medium grey silicified intermediate volcanics. The mafic rocks are medium grey to dark grey-green, and cryptocrystalline to very fine grained. Both mafic and intermediate volcanic rocks are affected by moderate to strong pervasive silicification, minor chloritisation and patchy to pervasive lithium alteration.

The granodiorite is medium grey to greenish grey, massive, coarse grained to porphyritic, and exhibits a salt- pepper appearance. The main mineral constituents are light grey to greenish white plagioclase (40-45 vol%), dark green to black amphibole, most likely hornblende (15-20 vol%), mica (20 vol%), represented by biotite and muscovite, grey quartz (10-15%vol) and minor epidote, chlorite and disseminated sulphides.
