Vision Lithium Inc. Reports High-Grade Cesium Discovery up to 1.94% Cs2O at Sirmac Property

Yves Rougerie, President & CEO comments: "The very high-grade cesium results suggest these dikes are highly fractionated LCT (lithium-cesium-tantalum) pegmatites with the potential of hosting economic cesium mineralization. Although not observed, the mineral pollucite, the principal mineral of cesium, is likely present. These cesium assay results are amongst the highest ever reported in the province of Québec. The provincial database of surface rock samples contains over 80,000 cesium assay results of which only one result is above 1% and less than ten are above 800ppm (ref SIGÉOM)."

Vision's Sirmac property is host to the #5 Dike pegmatite lithium deposit as well as the Clapier lithium occurrence 6 km to the ENE. A new area of mineralized pegmatites was discovered late in 2024 in the southern portion of the property, approximately 10 km SE of the #5 Dike. A single visit to the area led to the discovery of two pegmatite dikes in contact with basalts. The dikes outcrop minimally, and their size and extent are not currently known. However, spodumene was observed in both dikes and representative samples of pegmatite and the host rock basalt were taken from each site with the following results:

The dikes also exhibit highly anomalous values for lithium, tantalum and rubidium. These results are similar in many respects to values reported from the producing Tanco mine in Manitoba and the Case Lake exploration project in eastern Ontario, the two most significant cesium occurrences in Canada.

The highly anomalous values in the basalt samples for cesium and lithium indicate a strong alteration halo surrounding the pegmatite dikes. This suggests the dikes are potentially larger/wider at depth and/or along strike.

The exploration program was coordinated with Innovexplo of Val d'Or, Québec who contributed new interpretations of existing geological models for the property occurrences earlier in the year followed by field work that included outcrop visits and systematic structural measurements and a reinterpretation of pegmatite textures from drill core relogging (mainly from Dike #5). Proposals for new exploration concepts and targets resulted from this work. The new area discovery is also the result of this coordinated effort. Decades-old historical drilling for base metals in the southern area intersected pegmatite dikes which were not sampled at the time. Other dikes are likely present under overburden cover in the vicinity of the new dikes. A whole new corridor/swarm of LCT pegmatite dikes is possible in this area, fertile for both cesium and/or lithium-tantalum economic deposits. Future exploration will focus on this area for this obvious potential.

QA/QC

The sampling program was planned and supervised by InnovExplo Inc. Samples were transported from the Sirmac project to the ALS facility in Val-d'Or, Québec by InnovExplo personnel. The 1.5 to 3 kg grab samples were crushed to 70% less than two millimetres (CRU-31), riffle split, pulverize split to better than 85% passing 75 microns (PUL-31). Samples were assayed for lithium + 33 element by ICP-AES (ME-MS89L).

The scientific and technical information in this release has been reviewed and approved by Yves Rougerie, Geologist, President and CEO of the Company. Mr. Rougerie is a "qualified person" as defined in National Instrument 43-101 - Standards of Disclosure for Mineral Projects. The potential grades of exploration targets disclosed in this news release are conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
