The Ewoyaa Lithium Project as described in the Slides is at the exploration and development stage, and potential investors should understand that mineral exploration, development and mining are high-risk undertakings. The Slides contain statements which may be in the nature of forward-looking statements. CAUTIONARY STATEMENTS The information in the Slides that relates to Ore Reserves, Mineral Resources and Production Targets for the Ewoyaa Lithium Project was reported by the Company in the Definitive Feasibility Study announcement on 29 June 2023 and the updated Mineral Resource Estimate announcement on 1 February 2023. The Company confirms that it is not aware of any new information or data that materially affects the information included in the announcements and that all material assumptions and technical parameters underpinning the Mineral Resource estimates, Ore Reserve estimates, production targets and forecast financial information in the announcements continue to apply and have not materially changed. FORWARD-LOOKING STATEMENTS The Slides contain certain statements and expressions of belief, expectation or opinion which contain 'forward-looking information', and which relate, inter alia, to feasibility studies, the Company's proposed strategy, plans, objectives, performance, outlook, cash flow, projections, targets, and Mineral Resources and Ore Reserves or to the expectations or intentions of the Company's directors. Generally, this forward-looking information can be identified by the use of forward-looking information can be identified by the use of forward- looking terminology such as 'outlook', 'anticipate', 'project', 'target', 'likely', 'believe', 'estimate', 'expect', 'intend', 'may', 'would', 'could', 'should', 'scheduled', 'will', 'plan', 'forecast', 'evolve', and similar expressions.
