Forward-looking information includes but is not limited to information concerning the incoming or outgoing boards of HudBay Minerals, the cancelled shareholders’ meeting, the intentions of the incoming or outgoing boards, and the strategy and intentions of HudBay. Generally, forward-looking information can be identified by the use of forward-looking terminology such as “plans”, “expects”, or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, “understands” or “does not anticipate”, or “believes” or variations of such words and phrases or statements that certain actions, events or results “will”, “may”, “could”, “would”, “might”, or “will be taken”, “occur”, or “be achieved”. Forward-looking information is based on the views, opinions, intentions and estimates of management at the date the information is made, and is based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those anticipated or projected in the forward-looking information (including the actions of other parties who have agreed to do certain things and the approval of certain regulatory bodies).

Many of these assumptions are based on factors and events that are not within the control of HudBay and there is no assurance they will prove to be correct.
