Special Meeting of Mason Shareholders
A special meeting of Mason shareholders (the “Meeting”) will be held to consider the Arrangement at 10:30 a.m. (Vancouver time) on December 17, 2018 at the offices of Borden Ladner Gervais LLP located at 1200 Waterfront Centre, 200 Burrard Street, Vancouver, British Columbia.

After a thorough and careful review and consideration of the best interests of the Company, the terms of the Arrangement and its impact on Company shareholders, excluding Hudbay, its affiliates and any other persons required to be excluded in accordance with Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions (the “Public Shareholders”) and the Company’s other stakeholders, a special committee (the “Special Committee”) comprised solely of independent directors of the Company, unanimously concluded that the Consideration to be received by the Public Shareholders pursuant to the Arrangement is fair to such Public Shareholders and that the Arrangement is in the best interest of the Company.

ON THE UNANIMOUS RECOMMENDATION OF THE SPECIAL COMMITTEE, THE COMPANY BOARD UNANIMOUSLY RECOMMENDS THAT PUBLIC SHAREHOLDERS VOTE FOR THE ARRANGEMENT RESOLUTION.
