ISS and Glass Lewis recommend Mason Resources Shareholders vote FOR the Plan of Arrangement with Hudbay Minerals

Vancouver, BC, December 4, 2018 - Mason Resources Corp. (TSX: MNR; OTCQB: MSSNF – “Mason” or the “Company”) announces that Institutional Shareholder Services Inc. (“ISS”) and Glass Lewis & Co., LLC (“Glass Lewis”), have both recommended that Mason shareholders vote FOR the previously announced plan of arrangement with Hudbay Minerals Inc. (“Hudbay”) under Part 9, Division 5 of the Business Corporations Act (British Columbia) (the “Arrangement”). Pursuant to the Arrangement, Hudbay will acquire all the outstanding shares of the Company not already owned by Hudbay and its affiliates for C$0.40 per share (the “Consideration”).

Favourable ISS and Glass Lewis Recommendations
Both ISS and Glass Lewis, the two leading independent proxy advisory firms whose recommendations are relied upon by major institutional investment firms and other institutional shareholders, refer to the strong strategic rationale for the Arrangement, the significant premium, certainty of value from the cash Consideration, and favourable market reaction as factors supporting their FOR recommendations.

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. The record date for determining the Company shareholders entitled to receive notice of and vote at the Meeting has been fixed as the close of business on November 16, 2018 (the “Record Date”).

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, 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.



Required Approvals
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 who are present in person or represented by proxy at the Meeting; and (ii) a majority of the votes cast by Public Shareholders 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.

Shareholder Support Agreements
In connection with the Arrangement, all of the directors and senior officers of Mason as well as Mantos Copper (Bermuda) Limited (the “Supporting Shareholders”) entered into customary support agreements with Hudbay pursuant to which they have agreed to vote their shares, representing 19.8% of the issued and outstanding shares, in favour of the Arrangement. Together with Hudbay, the Supporting Shareholders hold 33.7% of the issued and outstanding shares.
