Critical Elements Lithium Corporation reported the results of exploration of multiple lithium-tantalum pegmatite trends with positive prospecting sampling results on the Duval and Lemare 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, 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 Quebec and management intends to catalyze the value inherent in this asset. 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 uninterrupted 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. 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% Li2O, 1.54% Li2O and 0.54% Li2O in an angular pegmatite boulder field that may have been transported one kilometres from the main discovery outcrops during glaciation.

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. 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% Li2O.

Recent high-grade results include up to 2.44% Li2O and 1.60% Li2O in situ pegmatite outcrop. This highlights the potential for future drilling to extend the LCT pegmatite trends 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.
