TORONTO, ON--(Marketwired - November 08, 2016) - HudBay Minerals Inc. ("Hudbay" or the "company") (HBM) today announced it has temporarily suspended operations at its Constancia mine in Peru as a result of trespassers in the open pit area. The decision is necessary for the safety of employees and the people occupying the site.

Many of the trespassers are from the district of Chamaca, about an hour from the mine, which within the last two weeks signed an agreement with national and local governments and Hudbay Peru confirming areas of social co-operation. The trespassers have yet to present specific demands.

Police are present to ensure the safety of people and assets and Hudbay Peru is working with representatives of the national and local governments, as well as other parties toward a goal of resolving the situation peacefully and safely.
