Refer to Sayona Mining ASX announcement "DFS Confirms NAL Value with A$2.2B NPV" dated April 14, 2023, a copy of which can be found on Sayona Mining's website. 33. Production target and economics include the use of inferred mineral resources which have a low level of geological confidence and as such we consider them to be at a scoping study level. Refer to cautionary note on page 3 of this presentation. See Atlantic Lithium announcement "Pre-Feasibility Study Delivers Robust Project Economics" dated September 22, 2022, a copy of which can be found on Atlantic Lithium's website.
