Critical Elements' 10,000-Meter Summer Drill Program at Rose West Continues to Deliver Positive Results

MONTRÉAL, QC / ACCESS Newswire / November 10, 2026 / Critical Elements Lithium Corporation (TSX-V:CRE)(OTCQX:CRECF)(FSE:F12) ("Critical Elements"or the "Corporation") is pleased to provide an update on the drilling program, geological interpretation and positive assay results on its Summer 2026 10,000 meters of systematic drilling around the 100% owned Rose West Discovery ("Rose West"), located in Eeyou Istchee, Québec.

Highlights

• The Summer 2026 drill program continues to deliver positive results demonstrating the successful expansion of the Rose West mineralized footprint by adding an additional 350 x 300 m block expanding the mineralization footprint in the North Extension Area, and an additional 200 x 300 m block in the West Target Zone. The mineralization footprint of Rose West has now been expanded over ten-fold since discovery in the winter of 2024.
• Drilling along Lines C and D suggests the continuity of Pegmatite 6 below the Main Target Area, where mineralization has been intersected along a west-dipping zone, over thicknesses ranging from 15 to 37.9 m.
• Combined, these new results and observations are providing key insights on the fine scale geometry of the zones, and the 3D model has been fully revised and updated and is being incorporated into planning for future drill program.
• All assay results have been received for ten additional holes, covering the North Extension Area.
• Since completion of hole RW-26-68, an additional 26 holes were also drilled and are being prepared for assaying.

The Summer 2026 drill program targets the expansion of the mineralized footprint to a potential of approximately 1,250 x 2,000 m and aims to expand the lateral continuity of the seven mineralized pegmatite bodies identified within the system. Previously reported drilling has covered the immediate eastern extension of the Main Target, and since then the program has completed the exploration drilling along the northern and western boundaries of the defined mineralized zones. Current drilling is focussing on infilling gaps in the core of the system in support of a Mineral Resource Estimate ("MRE").

Assay results were received for holes RW-26-59 to RW-26-68 inclusive, and returned some significant lithium and tantalum composite assays, as highlighted below:

• 0.58% Li₂O and 226 ppm Ta₂O₅ over 14.05 m, through Pegmatite 3B, in hole RW-26-59
• 1.35% Li₂O and 160 ppm Ta₂O₅ over 16.20 m (including 1.85% Li₂O and 93 ppm Ta₂O₅ over 9.25 m), through Pegmatite 3B, in hole RW-26-60
• 0.96% Li₂O and 163 ppm Ta₂O₅ over 5.15 m, through Pegmatite 3B, in hole RW-26-61
• 0.93% Li₂O and 162 ppm Ta₂O₅ over 6.30 m (including 3.39% Li₂O and 109 ppm Ta₂O₅ over 1.65 m), through Pegmatite 3B, in hole RW-26-62
• 0.15% Li₂O and 166 ppm Ta₂O₅ over 4.25 m, through Pegmatite 3B, in hole RW-26-63.
• 1.32% Li₂O and 280 ppm Ta₂O₅ over 3.20 m, through Pegmatite 3B, in hole RW-26-64.

* Core length; the true thickness is between 80 to 95% of the core length.

Located approximately 10 km to the west of the 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, now covering an overall footprint of 1,250 m x 1,500 m, (see Press Release dated August 12, 2026), a more than ten-fold increase in surface expression. The lithium-rich pegmatites typically range from 10 to 40 m in thickness and together display a sub-horizontal stacked geometry. Recent drilling has identified three new spodumene-bearing pegmatitic bodies within the target area. The Summer 2026 drill program is designed to further expand this mineralized footprint, and to better define the geometry and extent of the three new mineralized pegmatites intersected during the Winter 2026 Campaign.

The Summer 2026 drill program is designed to reach three specific goals:

1. Expand laterally all around the existing mineralized footprint;
2. Infill drilling along Line C and D, to confirm grade and thickness continuity of the intersected pegmatites;
3. Follow up on both newly discovered mineralized pegmatites (Pegmatites 6 and 7) below the current extent of mineralization.

The drilling program is expected to terminate at the end of November 2026. Figure 1 below presents the collar locations of all drill holes completed thus far, along with the remaining proposed ones. Drilling is now covering the core mineralized area with a systematic 100 m grid approach, while a fence of holes at 200 m spacing has closed off the known mineralized zones in the northern and western areas.

However, both the East Target Zone, where Pegmatite 7 was intersected at a depth of 330 m in hole RW-26-50, as well as the South Area, where Pegmatite 5 and 3 were intersected in holes RW-26-39 to RW-26-41, remain open for exploration.

The assay results reported in this release are from the drill holes meant to cover the North Extension Area, where an offset equivalent of either Pegmatite 3 or 5 had previously been reported in holes RW-26-57 and RW-26-58. The new drilling now confirms the presence of such offset equivalent of the main Pegmatite 3. This new zone, Pegmatite 3B, covers a 300 x 300 m area, while its thickness appears to gradually decrease towards the north.

As part of our systematic drilling approach, the NW Area as well as the West Extension area were also tested during this drilling phase. No significant mineralized zones were intersected apart from holes RW-26-74 and RW-26-75, where relatively thin but potentially mineralized spodumene-bearing pegmatites were intersected.

A last group of holes are planned to be completed by the end of the current drilling campaign. These holes are designed to close off the loop and covering with a similar gridded approach the area immediately East of the Main Target Area, while providing key insights on the potential continuity of mineralization intersected during the Winter in holes RW-26-38 and RW-26-43 to the south, and RW-26-47 and RW-26-48 to the north.
