PRESS RELEASE

CRITICAL ELEMENTS LITHIUM INTERCEPTS 1.04% LI 2O OVER 33.85 METERS IN

DRILLING AT LEMARE

June 20 th , 2023 - M ONTRÉAL ,Q UÉBEC – Critical Elements Lithium Corporation (TSX-V: CRE) (US OTCQX:

CRECF) (FSE: F12) (" Critical Elements " or the " Corporation ") is pleased to report results from the winter

drill program completed on the Lemare Project in th e James Bay region, Eeyou Istchee, Québec. During

winter 2023, the Corporation completed a 5,554-meter drill program, encompassing thirty-one drillholes to

test the known lithium bearing zone on the East-West extension, as well at depth. The best intercepts are

presented in Table 1 and Figure 2.

Selected drill intersection highlights include:

 LE-23-32: 1.04% Li 2O and 67.91 ppm Ta 2O5 over 33.85 m, including

 1.42% Li 2O and 74.24 ppm Ta 2O5 over 18.8 m

 LE-23-33: 0.88% Li 2O and 113.92 ppm Ta 2O5 over 12.90 m

 LE-23-35: 1.63% Li 2O and 104.30 ppm Ta 2O5 over 5.25 m

 LE-23-44: 1.51% Li 2O and 54.15 ppm Ta 2O5 over 4.95 m

 LE-23-48: 0.89% Li2O and 48.89 ppm Ta 2O5 over 7.10 m

 LE-23-49: 0.97% Li2O and 64.43 ppm Ta 2O5 over 8.85 m, including

 1.59% Li 2O and 61.34 ppm Ta 2O5 over 2.40 m.

Critical Elements controls one of the largest hard rock lithium exploration land positions in North America,

totalling 1,050 square kilometres specifically assembled for their geological setting and proximity to roads

and Québec’s 100% renewable energy grid. For exampl e, its land position includes the Corporation’s

advanced Rose lithium-tantalum project (“Rose”) and covers the extrapolated northeast and southwest

structural extensions of the Nemaska Belt, which hosts the Whabouchi mine being developed by Nemaska

Lithium.

Critical Elements has outlined its exploration plans in several news releases, most recently on February 1 ,

May 16 , and May 31 . In addition to demonstrating the value inherent in the Corporation’s exploration land

package, there are three goals:

1. Extend the life of the primary Rose project;

2. Advance the Lemare project toward an initial res ource estimate and technical studies if warranted;

and

3. Demonstrate the potential of new targets highlig hted via machine learning, or artificial intelligence.

The winter 2023 drilling program on the Lemare spodumene project confirmed the 400-metre extension to

the southwest and the 500-metre extension to the no rtheast of the main known spodumene-bearing

pegmatite with variable width and spodumene content . At least two different types of sub-parallel

pegmatites were intersected by the drilling. The ma in spodumene-bearing pegmatite features coarse

quartz-feldspar-muscovite, while the second pegmatite is aphanitic quartzo-feldspathic, is generally l ower

grade, and is only sporadically mineralized. The ma in spodumene-bearing pegmatite is controlled by a

northeast-southwest structure that is recut by at l east two north-south oriented faults. The informati on

collected during the winter drilling program will b e useful to better define the 3D model and better

understand the pinch-and-swell character of the peg matites at Lemare. The confirmed spodumene-

prospective pegmatite strike length at Lemare now e xceeds 2.2 kilometres. However, based on Goldspot

Discoveries’ machine learning methodology and surface sampling results, the LCT pegmatite trend on the

Lemare property has been estimated to extend for over 5 kilometres.

Critical Elements intends to pursue further work on Lemare over the summer with surface mapping and a

sampling program followed by incremental drilling. Lemare is well-situated within 3 kilometres of road

access and is an excellent candidate for initial te chnical studies. At the moment, the Corporation has

temporarily suspended exploration activities on the Nemaska Belt projects in the Eeyou Istchee-James Bay

region of Québec in accordance with a directive fro m the Ministère des Ressources Naturelles et des

Forêts, which has banned forest access on Crown land and closed roads to help combat forest fires across

the province.

Quality assurance/quality control

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

sampling and analysis of the core samples. The drill core was logged and then split, with one-half sent for

assay and the other retained in the core box as a w itness sample. Duplicates, standards and blanks

wereregularly inserted into the sample stream. The core samples were delivered, in secure tagged bags,

directly 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 usi ng 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, hi gh

purity Rose lithium project in Québec, the Corporat ion’s first lithium project to be advanced within a land

portfolio of over 1,050 square kilometers. On June 13 th , 2022, the Corporation announced results of a

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

for the Project is estimated at 82.4%, with an esti mated after-tax net present value of US$1.9 B at an 8%

discount rate. In the Corporation’s view, Québec is strategically well-positioned for US and EU markets and

boasts good infrastructure including a low-cost, low-carbon power grid featuring 94% hydroelectricity. The

project has received approval from the Federal Mini ster of Environment and Climate Change on the

recommendation of the Joint Assessment Committee, c omprised of representatives from the Impact

Assessment Agency of Canada and the Cree Nation Gov ernment and also received the Certificate of

Authorization pursuant to section 164 of Québec's Environment Quality Act from the Québec Minister of the

Environment, the Fight against Climate Change, Wildlife and Parks.

taken”, “occur” or “be achieved”. Forward-looking information contained herein include, without limitation, statements

relating to the results and completion of the 2023 exploration program, the permitting process, the results and outcome

of the Front-End Engineering Design Study, eligibility of equipment required for the Rose Project to the 30% investment

tax credit (ITC) announced by the Federal government in its last budget, as well as the outcome of the formal process

launched by the Corporation in connection with the Project financing. Forward-looking information is b ased on

assumptions management believes to be reasonable at the time such statements are made. There can be no assurance

that such statements will prove to be accurate, as actual results and future events could differ materially from those

anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking information.

from those contained in forward-looking information , there may be other factors that cause results not to be as

anticipated, estimated or intended. Factors that ma y cause actual results to differ materially from ex pected results

described in forward-looking information include, but are not limited to: final and complete results of the Corporation’s

2023 exploration program, the final outcome of the permitting process and the Corporation’s ability to meet all conditions

imposed thereunder, the final results of the Front-End Engineering Design Study and its effects on the development of
