[{"type":"text","content":" MONTRÉAL, QUÉBEC / ACCESS Newswire / May 21, 2026 / Critical Elements Lithium Corporation (TSX-V:CRE) (OTCQX:CRECF) (FSE:F12) (\"Critical Elements\" or the \"Corporation\") is pleased to provide the last assay results and an update on its Phase 1 Winter 2026 drill program, at the 100% owned Rose West Discovery (\"Rose West\"), located in Eeyou Istchee, Québec. Highlights The Phase 1 Winter 2026 drill program has delivered positive results demonstrating the successful expansion of the Rose West mineralized footprint from 450 m x 370 m to 1,250 m x 800 m, thicknesses that typically range from 10 to 40 m, and excellent lateral grade continuity. Newly discovered Pegmatite 5 is delivering substantial and laterally continuous intersections in the southern portion of the Main Target Area, part of a stacked and generally flat lying system. The geological model continues to prove to be highly effective and productive. Preparation is underway for an upcoming follow-up Summer 2026 Drilling Program. Assay results were received for the four remaining holes RW-26-38 to 40, and RW-26-43, and returned some significant lithium and tantalum composite assays, as highlighted below: 1.03% Li2O and 233 ppm Ta2O5 over 14.65 m (including 1.68% Li2O and 224 ppm Ta2O5 over 8.25 m), through Pegmatite 2, in hole RW-26-38 1.71% Li2O and 210 ppm Ta2O5 over 14.75 m (including 2.47% Li2O and 165 ppm Ta2O5 over 8.05 m), through Pegmatite 3, in hole RW-26-39 0.98% Li2O and 121 ppm Ta2O5 over 11,20 m, through Pegmatite 5 (new), and1.73% Li2O and 94 ppm Ta2O5 over 15.60 m (including 2.90% Li2O and 106 ppm Ta2O5 over 7.35 m), through Pegmatite 3, in hole RW-26-40 0.47% Li2O and 832 ppm Ta2O5 over 6.25 m (including 2.28% Li2O, 2,796 ppm Ta2O5 and 876 ppm Cs2O over 1.20 m), through Pegmatite 2, in hole RW-26-43 * Core length; the true thickness is between 80 to 95% of the core length. Rose West is situated within 10 km of the highly advanced Rose Lithium-Tantalum Project (\"Rose\"). Rose West is a near surface lithium-rich pegmatite bearing zone, initially intercepted by drilling over a 450 m x 370 m footprint area in the winter of 2024 (see Press Release dated February 3, 2026), now covering an overall footprint of 1,250 m x 800 m. The lithium-rich pegmatites typically range from 10 to 40 m in thickness and display a sub-horizontal geometry. Recent drilling has ide...
