This news release contains certain forward-looking statements concerning anticipated developments in PolyMet’s operations in the future. Forward-looking statements are frequently, but not always, identified by words such as “expects,” “anticipates,” “believes,” “intends,” “estimates,” “potential,” “possible,” and similar expressions, or statements that events, conditions or results “will,” “may,” “could,” or “should” occur or be achieved. These forward-looking statements may include statements regarding exploration results and budgets, reserve estimates, mineral resource estimates, work programs, capital expenditures, timelines including timelines for third-party studies and issuance of permits to operate by various government agencies, strategic plans, the market price of metals, costs, or other statements that are not a statement of fact. Forward-looking statements address future events and conditions and therefore involve inherent risks and uncertainties. Actual results may differ materially from those currently anticipated in such statements due to a variety of risks, uncertainties and other factors. PolyMet’s forward-looking statements are based on the beliefs, expectations and opinions of management on the date the statements are made, and PolyMet does not assume any obligation to update forward-looking statements if circumstances or management’s beliefs, expectations and opinions should change.
