HudBay Minerals Announces Sale of Fenix Project

Toronto, Ontario – August 5, 2011 – HudBay Minerals Inc. (“HudBay”, the “company”) (TSX/NYSE: HBM) announced that it has entered into a definitive agreement to sell 100% of its interest in the Fenix ferro-nickel project in Guatemala to the Solway Group. Pursuant to the terms of the agreement, HudBay will receive US$140 million in cash at closing and US$30 million upon the satisfaction of certain conditions during the course of Solway’s development of the project.

“While we believe that Fenix is a robust project that warrants development, the project does not fit our strategy of focusing on VMS and porphyry deposits,” said David Garofalo, president and chief executive officer. “We believe that the sale proceeds will further strengthen our balance sheet as we develop our Lalor and Constancia projects. We are also pleased to see the project in the hands of an experienced ferro-nickel operator, such as the Solway Group, which is committed to the development of Fenix.”

HudBay expects to record a non-cash charge related to its investment in Fenix of approximately $212.7 million in its consolidated financial results for the three months ended June 30, 2011.

Closing of the transaction is expected to occur in the third quarter of 2011.

HudBay’s financial and legal advisors on the transaction were Morgan Stanley & Co., Incorporated and Goodmans LLP, respectively.
