the Company to complete construction and commence commercial production within the targeted timing

or developments that the Company believes, expects or anticipates will or may occur is forward -looking

information, including statements regarding the potential development of mineral resources and mineral

reserves which may or may not occur. Forward -looking information contained herein is based on certain

assumptions regarding, among other things: general economic and political conditions; the stable and

supportive legislative, regulatory and community environm ent in the jurisdictions where the Company

operates; anticipated trends and effects in respect of the COVID-19 pandemic and post-pandemic; demand

for lithium, including that such demand is supported by growth in the electric vehicle market; the Company’s

market position and future financial and operating performance; the Company’s estimates of mineral

resources and mineral reserves, including whether mineral resources will ever be developed into mineral

reserves; and the Company’s ability to develop and ach ieve production at its mineral projects. Although

management believes that the assumptions and expectations reflected in the forward -looking information

are reasonable, there can be no assurance that these assumptions and expectations will prove to be correct.

Forward-looking information inherently involves and is subject to risks and uncertainties, including but not

limited to that the Company may not develop its mineral projects into a commercial mining operation; the

market prices for lithium may not remain at current levels; and the market for electric vehicles and other large

format batteries currently has limited market share and no assurances can be given for the rate at which this

market will develop, if at all, which could affect the success of the Company and its ability to develop lithium

operations. There can be no assurance that such statements will prove to be accurate, as actual results and

future events could differ materially from those anticipated in such statements. Accordingly, readers should

not place undue reliance on forward-looking information. The Company disclaims any intention or obligation

to update or revise any forward-looking information, whether because of new information, future events or

otherwise, except as required by law. For more information on the risks, uncertainties and assumptions that
