Hudbay Announces Receipt of Section 404 Water Permit for Rosemont

TORONTO, March 08, 2019 - HudBay Minerals Inc. (“Hudbay” or the “company”) (TSX, NYSE: HBM) announced today that the U.S. Army Corps of Engineers ("Army Corps") has issued a Section 404 Water Permit (the “404 Permit”) for Hudbay’s Rosemont Project. Rosemont has already received the Final Record of Decision from the U.S. Forest Service (“USFS”), a process that involved 17 co-operating agencies at various levels of government, 16 hearings, over 1,000 studies, and 245 days of public comment resulting in more than 43,000 comments. Now that the 404 Permit has been issued, Hudbay expects to receive Rosemont’s Mine Plan of Operations from the USFS shortly and looks forward to moving the project into development.

“The receipt of Rosemont’s 404 water permit is a major milestone in our efforts to build a modern mine that will fulfill the requirements of its permits, create jobs and provide benefits for all of our stakeholders,” said Alan Hair, Hudbay’s president and chief executive officer. “There is positive momentum at Rosemont and across our business as we continue to position Hudbay to create long-term and sustainable value for shareholders. We appreciate the diligence that the Army Corps has put into its consideration of Rosemont’s permit application, and look forward to advancing Rosemont into construction.”

Hudbay will continue to execute its plan regarding the Rosemont project and will provide updates as developments warrant.
