About Critical Elements Lithium Corp.

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 Quebec, the corporation's first lithium project to be advanced within a land portfolio of over 1,016 square kilometres. On Aug. 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 $2.2-billion (U.S.) at an 8-per-cent discount rate. In the corporation's view, Quebec is strategically well-positioned for US and EU markets and boasts good infrastructure including a low-cost, low-carbon power grid featuring 94-per-cent hydroelectricity. The project has received approval from the Federal Minister of Environment and Climate Change on the recommendation of the Joint Assessment Committee, comprising representatives from the Impact Assessment Agency of Canada and the Cree Nation government, received the certificate of authorization under the Environment Quality Act from the Quebec Minister of the Environment, the Fight against Climate Change, Wildlife and Parks, and the project mining lease from the Quebec Minister of Natural Resources and Forests under the Quebec Mining Act.
