ASX: PMT | TSX: PMET | OTCQX: PMETF | WB: R9GA 22pmet.ca Important Information Although the Company believes its expectations are based upon reasonable assumptions and has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. Key assumptions upon which the Company’s forward -looking information is based include without limitation, assumptions regarding development and exploration activities; the timing, extent, duration and economic viability of such operations, including any mineral resources or reserves identified thereby; the ability to achieve production and the timing thereof; the accuracy and reliability of estimates, projections, forecasts, studies and assessments; the Company's ability to meet or achieve estimates, projections and forecasts; the availability and cost of inputs; the price and market for outputs; foreign exchange rates; taxation levels; the timely receipt of necessary approvals or permits; the ability to meet current and future obligations; the ability to obtain timely financing on reasonable terms when required; the current and future social, economic and political conditions; and other assumptions and factors generally associated with the mining industry. Readers are cautioned that the foregoing list is not exhaustive of all factors and assumptions which may have been used. Forward-looking statements are also subject to risks and uncertainties facing the Company’s business, any of which could have a material adverse effect on the Company’s business, financial condition, results of operations and growth prospects. Some of the risks the Company faces and the uncertainties that could cause actual results to differ materially from those expressed in the forward - looking statements include, among others, requirements for additional capital, operating and technical difficulties in connection with mineral exploration and development activities; actual results of exploration activities, including on the Shaakichiuwaanaan Project ; the estimation or realization of mineral reserves and mineral resources; the timing and results of estimated future production; the costs of production, capital expenditures, the costs and timing of the development of new deposits, requirements for additional capital; future prices of spodumene; changes in general economic conditions; changes in the financial markets and in the demand and market price for commodities; lack of investor interest in future financings; the Company’s ability to secure permits or financing for the completion of construction activities; governmental and environmental approvals; the potential for major economies to encounter a slowdown in economic activity or a recession; and the Company’s ability to execute on plans relating to the Shaakichiuwaanaan Project. In addition, readers should review the detailed risk discussion in the Company’s most recent Annual Information Form filed on SEDAR+, with the ASX and available on the Company’s website for a fuller understanding of the risks and uncertainties that affect the Company’s business and operations. These risks are not exhaustive; however, they should be considered carefully. If any of these risks or uncertainties materialize, actual results may vary materially from those anticipated in the forward -looking statements found herein. Forward-looking statements contained herein are presented for the purpose of assisting investors in understanding the Company’s business plans, financial performance and condition and may not be appropriate for other purposes. The forward-looking statements contained herein are made only as of the date hereof. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by applicable law. The Company qualifies all of its forward-looking statements by these cautionary statements. Non-IFRS and other financial measures This Presentation includes non-IFRS financial measures and non-IFRS financial ratios. The Company believes that these measures provide additional insight, but these measures are not standardized financial measures prescribed under IFRS and therefore should not be confused with, or used as an alternative for, performance measures calculated according to IFRS. Furthermore, these measures should not be compared with similarly titled measures provided or used by other issuers. The non-IFRS financial measures and non -IFRS financial ratios used in this Presentation and common to the mining industry are defined below: ▪ Cash operating costs at site and cash operating costs at site per tonne: Cash operating costs at site is a non-IFRS financial measure which includes mining, processing, and site administration. Cash operating costs at site per tonne is a non-IFRS financial ratio which is calculated as cash operating costs at site divided by anticipated production expressed in tonnes. These measures capture the important components of the Company’s anticipated production and related costs and are used to indicate anticipated cost performance of the Company’s operations. ▪ Total cash operating costs (DAP Grande-Anse as POL) and total cash operating costs per tonne (DAP Grande-Anse as POL): Total cash operating costs (DAP Grande-Anse as POL) is a non-IFRS financial measure which includes mining, processing, site administration, and product transportation to Grande -Anse. Total cash operating costs (DAP Grande-Anse as POL) per tonne is a non -IFRS financial ratio which is calculated as total cash operating costs (DAP Grande - Anse as POL) divided by anticipated production expressed in tonnes. These measures capture the important components of the Company’s anticipated production and related costs and are used to indicate anticipated cost performance of the Company’s operations. ▪ All-in sustaining cost (AISC) and AISC per tonne: All -in sustaining cost is a non- IFRS financial measure which includes mining, processing, site administration, and product transportation to Grande -Anse and sustaining capital. All -in sustaining cost per tonne of spodumene concentrate is a non -IFRS financial ratio which is calculated as all -in sustaining cost divided by anticipated production expressed in tonnes. These measures capture the important components of the Company’s anticipated production and related costs and are used to indicate anticipated cost performance of the Company’s operations. The Company does not currently have operations and therefore does not have historical equivalent measures to compare and cannot therefore reconcile with historical measures.
