December 20th, 2023 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX-V: CRE) (US

OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Corporation") is pleased with the progress

being made to advance the unique Rose Lithium -Tantalum Project ( “Rose Project” ) in Eeyou Istchee,

Québec and, ultimately, achieve its vision to become a large -scale, sustainable, and reliable vertically

integrated supplier of lithium for the emerging electric vehicle and energy storage industries .

The Rose Lithium-Tantalum project (“Rose or the “ Project”) is situated within the Rose and Rose South

property blocks (Figure 1), which constitute 395 km2, or only 38% of the Corporation’s highly prospective

1,050 km2 exploration portfolio in Québec.

Summer 2023 Prospecting Results

During the summer of 2023, Critical Elements conducted a prospecting program over several areas,

including the Rose, Rose South, Rose North and Nemaska belt properties. The objective of the field

program was to identify new pegmatite bodies using systematic rock geochemical sampling of all pegmatite

bodies in order to refine the geological interpretation of the properties and prioritize further exploration work

including drilling. A total of 774 rock samples were collected (866 samples including QA/ QC) during the

exploration campaign with 95 samples reporting value s over 100 ppm Ta 2O5 and/or values over 0.10%

Li2O.

As reported on September 12 th, 2023 and in October 17th, 2023, the press releases state several new

outcrop discoveries have been identified in the Rose pegmatite swarm. To date, 4 spodumene -bearing

pegmatite outcrops have been identified in this New Discovery Area. At this early stage, the exact strike

length, width and orientations of these dykes is unknown, but the apparent strike length along the outcrops

exceeds 400m. All results from the summer program have now been received with selected results over

3% Li2O including 3.18% Li2O, 3.00% Li2O, 3.98% Li2O, 3.91% Li2O, and 5.10% Li2O. Full table of best

results is shown in Table 1. The reader is cautioned that grab samples are selective by nature and may not

represent average grades of the mineralization in the pegmatites. Table 1 provides all sample results with

2

values over 100 ppm Ta2O5 and/or values over 0.10% Li2O. Remaining samples did not return significant

values.

Project Financing and Strategic Partner Negotiations

Critical Elements is pleased to provide investors with an update on the ongoing assessment of expressions

of interest for financing and developing the Rose Project in collaboration with potential strategic partners.

Despite expectations for a conclusion ea rlier this year, the Corporation recognizes the intricacy of these

negotiations and due diligence, requiring time and thorough consideration. Investors can be assured of a

continued interest from potential partners, and that the Corporation believes that the process is progressing

positively. Management is committed to securing an optimal outcome for the Rose Project's financing and

development. We appreciate your continued support and patience as we work towards a mutually beneficial

partnership. Additionally, it is crucial to note that this process is progressing in tandem with the overall

development of the Rose Project, as detailed below.

The Rose Project Timeline

Critical Elements continues to work towards a Rose Project timeline that targets commencement of

production of high quality spodumene concentrate for chemical conversion and high purity technical

concentrate for the glass and ceramics industry in 2026. Furthermore, protecting the Rose Project’s timeline

has been a primary objective for management . Significant steps include the change in project scope to

incorporate the construction of our own 500 -worker camp 4km from the proposed mine site (see the

Feasibility Study filed on SEDAR + October 11, 2023 ). In addition, Critical Elements has commenced its

procurement program focused on ensuring long lead time items are available as needed, advanced detailed

engineering, and continued delivery of construction pre-conditions. These pre-conditions are required under

the Pihkuutaau Agreement signed in July 2019, the favorable decision statement from the federal Minister

of the Environment and Climate Change announced August 11, 2021, the Certificate of Authorization under

Section 164 of Québec’s Environment Quality Act announced November 2, 2022, and the mining lease

granted under the Québec Mining Act and announced September 18, 2023. Critical Elements is proud to

have achieved these very important milestones, which collectively ensure that eventual production is

8

achieved at the highest level s of environmental and cultural sustainability , an essential component in our

close relationship with our Cree neighbours in Eeyou Istchee and a unique quality highly valued input in the

global battery value chain.

Procurement Program

Critical Elements announces that following the order to purchase long lead time equipment (315 kV to 25

kV transformers – see press release October 12, 2023), the Corporation has now ordered several batches

of electrical equipment. These include 315 kV circuit breakers from industry -leading GEPR Energy

Canada Inc. (GE). These purchases will secure the start-up of the power station as quickly as possible.

Jean-Sébastien Lavallée, Chief Executive Officer of the Corporation stated: "Once again, Critical Elements

has taken action to reduce the risks related to the Rose Project schedule. We are getting closer and closer

to our goal of becoming a lithium producer for the electric car market."

Detailed Engineering and Construction Pre-Conditions

The Corporation has been working over the last several months to meet extensive pre -construction

requirements under governmental authorizations:

- The fish habitat compensation plan and the wetland compensation plan in Cree territory have been

updated in collaboration with stakeholders and are now submitted to federal and provincial

authorities for approval.

- The new camp location has been confirmed, and the environmental impact assessment with this

new camp and new borrow pits has been completed and filed to the authorities for approval.

- The summer monitoring program and field surveys have been completed.

Detailed engineering continues to progress well, while working to optimize the planned facilities of the Rose

Project:

- Detailed engineering continues to advance with a high degree of confidence consistent with the

Rose Project timeline.

- Following the LIDAR flyover, up to date topographical data was available, which allowed the

engineering team to further refine earthworks design.

- Site-wide water balance and water management strategy has been reviewed with updated data.

This has enabled design optimization of the water storage pond and mine water treatment plant.

- Design of the co -disposition stockpile progressed well, modelling of its phases over time is

completed. Stability analysis is underway.

- Technical specifications were issued for major process equipment, allowing the tendering process

to be initiated. Firm proposals have been received for the first set of equipment and are under

technical and commercial analysis.

- The procurement management program to purchase long lead items is on schedule to support the

Rose Project Concentrator detailed engineering.

Exploration Update

Critical Elements has recently received the required drilling permit and has initiated preparation for a drilling

program on the exciting new discovery discussed above located only 8km west of the Rose Project (see

press release s dated September 12th, 2023 and October 17 th, 2023 ), located within a portion of the

Corporation’s highly prospective 1,050 km 2 exploration portfolio. The objective of the drilling program is to

test, confirm and expand the new zone identified by prospection during the summer. The Corporation plans

to start with a program of approximately 5,000m during its winter program on the new discovery with the

objective to quickly test the dimension and grade of the new zone and assess the potential to expand the

Corporation’s mineral resource inventory. The drilling program will be adjust ed and, potentially, expanded

based on results of the initial drilling results on the new discovery.

Quality assurance/quality control

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

sampling and analysis of the samples. Standards and blanks were regularly inserted into the sample

stream. The 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
