Article content

During the final validation and completion of the PFS in the Technical Report, minor adjustments were made to the classification of capital and operating costs of the Clearwater Project. A summary of these changes is shown in the table below, compared to the originally reported figures.

Finalized by the QP’s, the capital expenditure for carbonation is now reclassified to be included with the lithium extraction and purification unit costs. Economic metrics have been slightly adjusted, as the initial working capital has been excluded from the economic assessment and reclassified as a corporate cost. Abandonment costs and major maintenance are now included in capital expenditures rather than operating expenses.

The Technical Report was prepared for E3 Lithium by Daron Abbey, M.Sc., P. Geo of Matrix Solutions Inc; Alex Haluszka, M. Sc., P. Geo of Matrix Solutions Inc; Meghan Klein, P. Eng, of Sproule Associates Limited; Antoine Lefaivre, P. Eng, of Sedgman Canada Ltd.; and Keith Wilson, P. Eng., of Stantec Consulting Inc., each of whom is a “Qualified Person” as defined under NI 43-101 (collectively, the “Qualified Persons”). Each of the Qualified Persons prepared or supervised the preparation of the information that forms the basis of the PFS; has reviewed and approved the technical information in this news release within their area of expertise; and is independent of E3 Lithium.

We encourage readers to review the Technical Report in its entirety, including all assumptions, qualifications, and exclusions.
