PRESS RELEASE

Critical Elements Lithium completes drill program at Rose West Discovery and

intercepts multiple, wide spodumene-rich pegmatites

March 13th, 202 4 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX -V: CRE) (US

OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Corporation") is pleased to announce

completion of a 31-hole, 3,670-meter drill program on its 100% owned Rose West Discovery with multiple

spodumene-rich pegmatites intersected.

The Rose West Discovery (“Rose West”) is situated within the Rose and Rose South property blocks

(Figure 1) , which constitute 395 km2, or only 38% of the total 1,050 km2 in the Corporation’s highly

prospective exploration portfolio in Québec.

The 2024 winter drill campaign successfully completed 3 ,670 meters of drilling in 3 1 holes on the

spodumene-bearing pegmatite showings discovered during the 2023 summer prospection campaign,

herein referred to as Rose West. Drilling results demonstrated the continuity of a mineralized pegmatite

body thus far over 450m strike, 370m down dip and to a vertical depth of 140m. In the west, the body is

comprised of multiple near surface mineralized pegmatites that range up to an apparent thickness of 12.4m

individually. These bodies appear to coalesce into a more substantial spodumene-bearing pegmatite in the

east with an apparent width of up to 40.4m . The near surface pegmatites appear to strike northwesterly

with a gentle dip of 15°, while the thicker pegmatite appears to strike easterly with a near -horizontal dip of

13°. The body is still open in all directions, while the greatest exploration potential appears to be to the east.

Mineralized intercepts are summarized in Table 1.

Initial assay results from the drill program have been received for the first two holes, RD-24-01 and RD-24-

02. Both drill holes returned high grade results with 1.61% Li2O and 135ppm Ta2O5 over 6.9m, including

2.17% Li 2O over 4.3m in hole RD-24-01, and 1.00% Li2O and 285 ppm Ta2O5 over 8.65m , including

1.34% Li2O and 376 ppm Ta 2O5 over 4.4m in hole RD-24-02. In addition to these early intersections of

lithium-rich pegmatites, the program also discover ed a different style of mineralization associated with an

aplite dyke with high grade tantalum values, including 571 ppm Ta2O5 over 1.1m. A summary of the assay

results received to date is presented in Table 2.

Jean-Sébastien Lavallée, Chief Executive Officer of the Corporation, stated: “Drill confirmation of high -

grade lithium mineralization at Rose West is the beginning of an important new chapter for Critical

Elements. While management is focused on delivery of a project financing package for the Rose Project

that minimizes shareholder dilution, the resumption of drilling on the Corporation’s extensive land position

should begin to crystalize that position’s value for shareholders . Additional drilling on multiple promising

targets identified on Critical Elements’ large, prospective land position could also yield economically

valuable mineralization later this year. ”

Quality assurance/quality control

Quality assurance and quality control procedures have been implemented to ensure best practices in

sampling and analysis of the drill core samples. Standards, duplicate and blanks were regularly inserted

into the sample stream. The drill core samples were delivered, in secure tagged bags to the ALS Minerals

laboratory facility in Val-d'Or, Quebec. The samples are weighed and identified prior to sample preparation.

The samples are crushed to 70% minus 2 mm, then separated and pulverized to 85% passing 75 μm. All

samples are analyzed using sodium peroxide fusion ME -MS-89L, with full analysis for 52 elements. Value

over 25,000 ppm Li were re -assays using Li -ICP-82b and value over 2,500 ppm Ta 2O5 were re-assays

using Ta-XRF10.

About Critical Elements Lithium Corporation

Critical Elements aspires to become a large, responsible supplier of lithium to the flourishing electric vehicle

and energy storage system industries. To this end, Critical Elements is advancing the wholly owned, high-

purity Rose Lithium-Tantalum project in Québec, the Corporation’s first lithium project to be advanced within

a land portfolio of over 1,050 km 2. On August 29, 2023, the Corporation announced results of a new

Feasibility Study on Rose for the production of spodumene concentrate. The after-tax internal rate of return

for the Project is estimated at 65.7%, with an estimated after -tax net present value of US$2.2B at an 8%
