Board Recommendation

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 and its affiliates (the “Public Shareholders”) and the Company’s other stakeholders, a special committee (the “Special Committee”) comprised solely of independent directors of the Company, has 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.

To be effective, the Arrangement must be approved by a special resolution passed by (i) at least two-thirds of the votes cast by Company Shareholders (including Hudbay) who are present in person or represented by proxy at the Meeting; and (ii) a majority of the votes cast by Public Shareholders, in accordance with Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions who are present in person or represented by proxy at the Meeting. In addition, the Supreme Court of British Columbia (the “Court”) must approve the Arrangement as a condition to its effectiveness. Among other things, the Court’s final order will include a finding on the fairness of the terms and conditions of the Arrangement to Public Shareholders participating in the Arrangement.
