Beyond Lithium Inc. announced that recent exploration work at the Company's Cosgrave Lake Project indicate the proximity to the potential discovery of a high-grade lithium spodumene zone. Regional Geological Context: The Cosgrave Lake Project is located in the Georgia Lake District. This district is an active and prolific lithium exploration area with more than 28 lithium occurrences recorded by Ontario Geological Survey that are hosted in five major pegmatite groups including the MNW, the Georgia Lake, the Barbara Lake, the Postogoni Lake, and the Forgan Lake (Breaks 2008).

Beyond Lithium has three projects in the Georgia Lake District: Cosgrave Lake (8,993 ha), Gathering Lake (6,948 ha), and Arrel Lake (3,585 ha). These Projects are located next to: Imagine Lithium's Jackpot Lithium Project which has a historical resource in the Main zone with 2 Mt at 1.09% Li2O. Rock Tech Lithium's Georgia Lake Project which has published a pre-feasibility study in November 2022 with a Mineral Resource estimate of a total indicated mineral resources of 10.6mt grading 0.88% Li2O and a total inferred mineral resource of 4.2mt grading 1.00% Li2O.

Balkan Mining's3 flagship Gorge Lithium Project where they recently commenced drilling. Infrastructure: The Cosgrave Lake Project can be accessed via the Trans-Canada Highway and a network of well- maintained logging roads. The Project is less than 20km north of the town of Nipigon, and about 100km to the northeast of Thunder Bay.

The Project also has excellent nearby infrastructure including ports, powerline, local labor force and equipment, and communications. Geology and Generic LCT Deposit Scientific Model: The host of several well-known fertile plutons namely the MNW pluton, the Barbara Lake pluton, and the Pine Portage pluton. These well-established fertile plutons in the Georgia Lake District are associated with several prolific lithium pegmatite belts including the Imagine Lithium's1 Jackpot Project and Rock Tech Lithium's2 Georgia Lake Project.

Beyond Lithium started its prospecting program at the Cosgrave Lake Project in late May 2023 and discovered a new LCT pegmatite intrusive stock, the Allen Graeme (AG) pluton. The AG Pluton shares similarities with other significant lithium discoveries in the Georgia Lake District, namely the MNW pluton, the Barbara Lake pluton, and the Pine Portage pluton. Worthy of note is that the chemistry of the Cosgrave Lake granite source (the Glacier Lake Batholith) and the AG pluton is quite similar to the concentration in the Tanco source and Tanco pluton located at Bernie Lake, Manitoba.

In other words, the size and geochemical characteristics of the AG Pluton indicate its potential as a source of concentrated fluids, volatiles, lithium, and rare earth minerals, making it an exceptionally promising area for exploration. Beyond Lithium advanced the exploration at the Cosgrave Lake Project to a Phase 2 program after the discovery of the AG pluton. The Phase 2 program focused on the detailed and systematic mapping and sampling of the property starting from the core of the AG pluton and moving outwards in order to identify the mineral fractionation trend for lithium mineralization.

To date, Beyond Lithium has collected a total of 133 grab samples and recorded more than 4,000 field data points of lithology and mineralogy at the Cosgrave Lake Project. The Phase 2 program successfully delineated a mineral zonation around the AG pluton transitioning from a pegmatitic textural border zone to a beryl zone and to a green muscovite zone. Just outside of the green muscovite zone located the furthest away from the AG pluton to the northeast, a grab sample from a pegmatite composed of quartz, feldspar, and alluaudite minerals returned with 0.39% Li2O (1,832ppm Li) and 2.77% Mn.

The mineral zonation at the Cosgrave Lake Project is comparable with the mineral zonation of the MNW lithium occurrence associated with the MNW stock located 2.8km north of Cosgrave Lake Project. The MNW spodumene-bearing pegmatite with up to 5.82% Li2O transitions from beryl-tourmaline at the border zone to muscovite-alluaudite in the intermediate zone then to spodumene-quartz in the core zone (Zayachkivsky 1985). The mineral and lithium grade zonation at the Cosgrave Lake Project resemble the generic lithium-cesium-tantalum ("LCT") pegmatite fractionation scientific model which signifies and proves: The AG pluton is a fertile stock that is concentrated of lithium-bearing volatiles to form LCT pegmatites.

The fractionation trend evolves outwards around the AG pluton and generally follows the overall northeast-southwest granite-metasedimentary contact orientation. The 0.39% Li2O grab sample with 2.77% Mn in pegmatite with alluaudite indicates the pegmatite is highly fractionated supported by the high manganese, Mn, and lower iron ratio (Breaks 2004). The 0.39% Li2O grab sample in pegmatite also implies the proximity to the potential discovery of a higher-grade lithium spodumene zone.

Measuring the ratio variations between potassium (K), cesium (Cs), rubidium (Rb) in samples is a common and useful exploration tool to display the fractionation trend or the relative degree of evolution of S-type, peraluminous granites and related pegmatite granites and the rare-element pegmatite groups that fractionated from the parent granitic rocks. With increasing fractionation of the pegmatite-forming melt, the compositions of the potassium feldspar and mica become more enriched in rubidium and cesium thus the fractionation trend point to the lower left corner in the plot as the higher fractionated area. Generally, pegmatites with the highest degree of fractionation have a K/Rb ratio of less than 30 (Breaks 2004).

The log of K/Cs ratio against the log of K/Rb ratio outlining the higher fractionated samples in the lower left corner of the plot with an average of 167ppm Li and 36 K/Rb and the lower fractionated samples in the top right corner of the plot with an average of 63ppm Li and 170 K/Rb which suggest the H fractionation zone is proximal to the potential spodumene zone. The high (H), moderate (M), and low (L) fractionated samples and the three zones, H, M, and L, outlines coincide with the mineral zonation where the border zone correlates with the low fractionation zone, the beryl zone correlates with the low to moderate fractionation zones, and the green muscovite zone correlates with the moderate to high fractionation zones. This strong correlation between the fractionation trend and the mineral zonation at Cosgrave Lake supports the fertility of the AG Pluton that it has high concentration of lithium volatiles to fractionate.
