Critical Elements Lithium Samples Up To 2.22% Li2O At Duval And 2.44% Li2O In The Southwestern Extension Of Lemare

MONTREAL, QC / ACCESSWIRE / September 5, 2023 / Critical Elements Lithium Corporation (TSX-V:CRE)(US OTCQX:CRECF)(FSE:F12) ( "Critical Elements" or the "Corporation" ) is pleased to report the results of exploration of multiple lithium-tantalum pegmatite (" LCT pegmatite" ) trends with positive prospecting sampling results on the Duval ( Table 1 ) and Lemare ( Table 2 ) sites.

Progression of the wholly owned Rose lithium-tantalum deposit toward a final investment decision is Critical Elements' primary goal. Rose is one of the most advanced hardrock lithium development projects in North America (see updated feasibility study results in the news release dated August 29, 2023), with key environmental permits and crucial Impact and Benefits Agreement in place. However, the Corporation also owns over 1,050 square kilometres of concessions that are highly prospective in the Eeyou Istchee region of Québec and management intends to catalyze the value inherent in this asset. To this end, Critical Elements launched a surface exploration program as announced in the news release dated May 31, 2023.

During June 2023, Critical Elements conducted a prospecting program over several areas of the Corporation's Nemaska belt property portfolio using ground-based and helicopter-borne teams of geologists. The program was interrupted for several weeks due to the unprecedented wildfire situation in the region. The Corporation is deeply concerned by the damage caused to the environment, as well as the negative impact on the people of Eeyou Istchee. Our teams have now returned to the field to continue with the planned program. The program's objective is to identify new pegmatite bodies using systematic rock geochemical sampling of ranked LCT-pegmatite targets as defined by ALS Goldspot "SmartTarget" methodology, which combines both expert-driven and machine-learning data-driven targeting approaches to refine the geological interpretation of the properties for further exploration work.

A total of 108 rock samples were collected during the short exploration campaign of June 2023. Prospecting confirms the discovery of the new two-kilometre-long trend of white pegmatite on the Corporation's 100% owned Duval property that hosts several lithium, cesium, and tantalum anomalies. Individual results include 2.22% Li 2 O, 1.54% Li 2 O and 0.54% Li 2 O in an angular pegmatite boulder field that may have been transported one kilometre from the main discovery outcrops during glaciation ( Table 1 and Figure 1 ). These mineralized pegmatites are spatially associated with mafic volcanics along an interpreted regional-scale shear zone that borders the Nemiscau Belt, in a similar geological setting that extends to the Whabouchi lithium deposit, three kilometres off the claims to the northeast ( Figure 3 ). These results begin to show the potential of the Corporation's Nemaska trend properties.

In addition, the Corporation has received sample results confirming the summer 2022 discovery of the extension of the LCT pegmatite trend on the Lemare property marked by a sample grading 0.38% Li 2 O. Recent high-grade results include up to 2.44% Li 2 O and 1.60% Li 2 O ( Table 2 and Figure 2 ) in in situ pegmatite outcrop. This highlights the potential for future drilling to extend the LCT pegmatite trend to over 5 kilometres on the Lemare property.

The reader is cautioned that grab samples are selective by nature and may not represent average grades of the mineralization in the pegmatites.

The surface exploration program with five crews continues to ground-truth several LCT-pegmatite targets. Results will be released in context as the program progresses. Management is currently engaged in designing a significant fall and winter drill program with multiple rigs to drill-test new targets including the Duval discovery, advance the Lemare deposit, and expand the Rose project resource inventory including protential proximal satellite mineralization. Details of this extensive program will be forthcoming near-term.

Quality assurance/quality control

Quality assurance and quality control procedures have 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 witness sample. Duplicates, standards and blanks were regularly 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 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 Ta2O5 were re-assays using Ta-XRF10.

The Corporation has resumed its mineral exploration and development programs as of early August 2023, as the wildfires in the region gradually abate. This includes surface exploration program over the Rose, Rose North and South and Nemaska Belt properties with five crew support by helicopter. Additionally, the corporation is conducting environmental baseline fieldwork, lidar survey and geotechnical work on Rose site to support the advancement of the details engineering work.

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 project in Québec, the Corporation's first lithium project to be advanced within a land portfolio of over 1,050 km2. 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% 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 Minister of Environment and Climate Change on the recommendation of the Joint Assessment Committee, comprised of representatives from the Impact Assessment Agency of Canada and the Cree Nation Government 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.
