The run‐of‐mine ore from Authier will be transported to the NAL site, where it will be blended with the NAL ore material using a ratio of 33% Authier / 67% NAL and fed to the primary crusher. The assumptions made for Authier and incorporated in the NAL PFS are compliant with the upcoming Authier feasibility study. Furthermore, the Authier project’s economics remain in line with Sayona’s expectations. The Company will continue to pursue opportunities to optimise and enhance the value of the project, including: Further metallurgical test work to improve processing metallurgical recoveries. The PFS assumes a metallurgical recovery of 67.7% for blended ore from NAL and Authier and 65.8% for NAL ore only; and Completing a Feasibility Study to assess the economic and technical viability of producing lithium hydroxide and/or carbonate from NAL spodumene concentrates at a site to be determined. Further definition of the geological model to be completed. This includes more sampling for lithium and iron grades, as well as modelling and further characterisation of the waste. Sayona has an extensive tenement footprint in the Abitibi area and there is potential to significantly increase its resource base and mine life. Completion of binding offtake agreements with partners that could potentially offer higher spodumene prices in line with current market levels I would welcome any comment in regard to the pricing and ratios mentioned below.

I realise it was at MOU stage only and that things may have changed since May 2022.
