Executive Summary
This technical report outlines the updated definitive feasibility study for the Authier Lithium Project, owned by Sayona Mining Limited. The project focuses on the extraction of lithium-bearing ore to support regional supply chains.
A key operational aspect of the project is the strategic partnership with the North American Lithium (NAL) operation. Under a memorandum of understanding, the Authier project will mine ore and ship it to the NAL concentrator for processing. Consequently, this specific technical report does not detail on-site processing methods, referring instead to the 2023 NAL Definitive Feasibility Study for milling and recovery specifications.

Executive Summary
This Preliminary Economic Assessment (PEA) outlines the development of the Authier Lithium Property located in Abitibi, Quebec, Canada. The project proposes an open-pit mine processing 803,000 tonnes of ore annually through a conventional lithium flotation process plant. The design targets the production of approximately 103,000 tonnes per year of spodumene concentrate at a grade of 6.0% Li2O. The process circuit includes crushing, grinding, scrubbing, desliming, flotation, magnetic separation, and concentrate dewatering.
The economic analysis assumes a base case spodumene concentrate price of $525/tonne. Sensitivity analysis indicates the project is primarily sensitive to processing recovery and concentrate value. The report recommends additional laboratory and pilot plant tests to validate recovery at lower head grades (0.91% Li2O) compared to the test samples (1.23% Li2O). Infrastructure plans include on-site processing facilities, tailings management, and off-site railway connections for concentrate shipping.
Processing Profile
- Crushing: Jaw Crusher, Cone Crusher
- Milling: Ball Mill
- Flotation: Rougher, Scavenger, Cleaner Cells
