Approval of the Rehabilitation and Restoration Plan Concerning the Rose Lithium-Tantalum Mining Project

Critical Elements Lithium Corporation (the "Company" or "Critical Elements") (TSXV:CRE)(OTCQX:CRECF)(FSE:F12) is pleased to announce that the Québec Minister of Energy and Natural Resources (the "Minister") has approved the rehabilitation and restoration plan concerning the Rose Lithium-Tantalum Mining Project (the "Rose Lithium-Tantalum Project" or the "Project

The approval of the rehabilitation and restoration plan is a prerequisite to the granting of the mining lease that will be necessary to move forward with the Project. The rehabilitation and restoration plan contains, in particular the description of the rehabilitation and restoration work relating to the Project and a detailed estimate of the expected costs to be incurred for completing the work. Now that the rehabilitation and restoration plan is approved, the Corporation must furnish a guarantee covering the anticipated cost of completing the work required under the rehabilitation and restoration plan, in accordance with the schedule of payments established pursuant to applicable laws.

"We are very pleased with the decision regarding the rehabilitation and restoration plan for the Rose Lithium-Tantalum Project, which is a necessary step toward securing the mining lease," stated Jean-Sébastien Lavallée, CEO of Critical Elements.

With the approval of the plan, the Company is making progress in the overall approval process for the Project. In August 2021, Critical Elements announced that the Federal Minister of Environment and Climate Change had rendered a favourable decision in respect of the proposed Rose Project. In a Decision Statement, which included the conditions to be complied with by the Company, the Minister confirmed that the Project is not likely to cause significant adverse environmental effects when mitigation measures are taken into account (see the Company's news release dated August 11, 2021, for more details). The final remaining step in the Project's approval is the completion of the provincial permitting process, which runs parallel to the federal process. Pursuant to the James Bay and Northern Quebec Agreement (JBNQA), the provincial environmental assessment is conducted jointly by the Cree Nation Government and the Government of Quebec under the Environmental and Social Impact Review Committee ("COMEX"). The provincial assessment is well advanced and has undergone several rounds of questions from COMEX that have been answered by Critical Elements in the normal course of the assessment process. At this time, Critical Elements has received no further questions from COMEX and remains confident in a positive outcome.
