TORONTO, March 08, 2021 - HudBay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE:HBM) today announced that it has completed its previously announced offering of US$600 million aggregate principal amount of 4.50% senior notes due 2026 (the "New Notes"). The New Notes will be governed by an indenture, dated as of March 8, 2021, among the company, the subsidiaries of the company party thereto as guarantors and U.S. Bank National Association, as trustee.
