Such statements in this news release include, but are not limited to, statements with respect to the future potential economic viability of the Project,, the estimation of mineral resources, mineral reserves and mineral prices, steps to be taken towards commercialization of the Project, the timing and amount of estimated future production and capital, operating and exploration expenditures and include, for greater certainty, all estimates in the PFS such as the cash, flow, IRR, NPV's, initial capital and life of mine production. Such statements are subject to risks and uncertainties that may cause actual results, performance or developments to differ materially from those contained in the statements. No assurance can be given that any of the events anticipated by the forward-looking statements will occur or, if they do occur, what benefits the Company will obtain from them.

A number of risks and uncertainties could cause our actual results to differ materially from those expressed or implied by the forward-looking statements, including: (1) the mineral resource and mineral reserve estimates relating to the Project could prove to be inaccurate for any reason whatsoever, (2) the Company may be unable to obtain financing for the Project on acceptable terms or at all, (3) prices and demand for nickel, cobalt or battery products could decline, (4) Project costs could differ substantially from those anticipated in the PFS and make any commercialization uneconomic, (5) inferred and indicated resources may not materialize, (6) permits, environmental opposition, government regulation, cost overruns or any of many other factors may prevent the Company from commercializing the Project, (7) additional but currently unforeseen work may be required to advance to the feasibility stage, and (8) even if the Project goes into production, there is no assurance that operations will be profitable.
