The Company previously completed a preliminary economic assessment NI 43-101 technical report on January 6, 2022, effective November 21, 2021 ("PEA"), however, given the exploration work completed since and the new mineral resource estimate of August 28, 2023 and included in the Technical Report, the Company does not consider the PEA current and therefore the Wicheeda REE Project is no longer considered an "advanced property" as that term is defined under applicable securities laws.
