2019 No. 22

Hudbay Will Appeal Unprecedented Rosemont Court Decision

Toronto, Ontario, August 1, 2019 – Hudbay Minerals Inc. (“Hudbay” or the “company”) ( TSX, NYSE: HBM)

announced that late yesterday the U.S. District Court for the District of Arizona (“Court”) issued a ruling in the lawsuits

challenging the U.S. Forest Service ’s issuance of the Final Record of Decision (“FROD”) for the Rosemont project in

Arizona. The Court ruled to vacate and remand the FROD such that Rosemont cannot proceed with construction at

this time. Hudbay believes that the Court has misinterpreted federal mining laws and Forest Service regulations as

they apply to Rosemont. As such the company will be appealing the Court’s decision to the U.S. Ninth Circuit Court of

Appeals. The FROD was issued in June 2017 after a thorough process of ten years involving 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 36,000 comments.

“We are extremely disappointed with the Court’s decision . We strongly believe that the project c onforms to federal

laws and regulations that have been in place for decades .” said Peter Kukielski, Interim President and Chief

Executive Officer. “We will be appealing the decision as we evaluate next steps for the Rosemont Project.”
