HUDBAY MINERALS INC.
NOTICE OF ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS
NOTICE IS HEREBY GIVEN that an annual and special meeting of shareholders (the "Meeting") of Hudbay Minerals Inc. ("Hudbay") will be held by way of a virtual meeting, accessible at https://web.lumiagm.com/298892851, on Thursday, May 21, 2020 at 10:00 a.m. (Eastern Time), for the following purposes:
1. to receive Hudbay's audited consolidated financial statements for the years ended December 31, 2019 and 2018 and the auditor's report thereon;
2. to elect the directors of Hudbay;
3. to appoint Deloitte LLP as Hudbay's auditor for the ensuing year and to authorize the Board of Directors, upon the recommendation of the Audit Committee, to fix the auditor's remuneration;
4. to consider and, if deemed appropriate, to approve a non-binding advisory resolution on executive compensation; and
5. to transact such other business as may properly come before the Meeting or any postponement or adjournment thereof.
The specific details of the matters proposed to be put before the Meeting are set forth in the accompanying Management Information Circular (the "Circular"). As described in the Circular, due to the COVID-19 pandemic, shareholders will not be able to attend the Meeting in person, in line with our commitment to taking all prudent precautions to ensure the health and safety of our employees, shareholders and other stakeholders.
Hudbay is holding the Meeting as a completely virtual meeting, which will be conducted via live webcast, where all shareholders regardless of geographic location will have an opportunity to participate at the Meeting.
Registered shareholders and duly appointed proxyholders will be able to attend, participate and vote at the Meeting online at https://web.lumiagm.com/298892851. Non-registered shareholders (being shareholders who hold their Shares through a broker, investment dealer, bank, trust company, custodian, nominee or other intermediary) who have not duly appointed themselves as proxyholder will not be able to vote at the Meeting. However, such non-registered shareholders may still attend the Meeting as guests.
Shareholders who wish to appoint a person other than the management nominees identified on the form of proxy or voting instruction form (including a non-registered shareholder who wishes to appoint themselves to attend) must carefully follow the instructions in the Circular and on their form of proxy or voting instruction form. These instructions include the additional step of registering such proxyholder with our transfer agent, TSX Trust Company, after submitting their form of proxy or voting instruction form. Failure to register the proxyholder with our transfer agent will result in the proxyholder not receiving a Control Number to participate in the Meeting and only being able to attend as a guest.
Shareholders who are unable to attend the virtual Meeting are requested to complete, date, sign and return the enclosed form of proxy so that as large a representation as possible may be had at the Meeting.
Hudbay's Board of Directors has fixed the close of business on April 9, 2020 as the record date, being the date for the determination of the registered holders of Hudbay common shares entitled to receive notice of and vote at the Meeting or any postponement or adjournment thereof. Shareholders who acquire common shares after April 9, 2020 should make arrangements with the selling shareholder to direct how such common shares will be voted at the Meeting.
Proxies to be used or acted upon at the Meeting or any postponement or adjournment thereof must be deposited with Hudbay's transfer agent, TSX Trust Company, by completing and delivering the form of proxy in accordance with the instructions indicated thereon, no later than 10:00 a.m. (Eastern Time) on May 19, 2020 or 48 hours (excluding Saturdays, Sundays and holidays) before any postponement or adjournment of the Meeting. Late proxies may be accepted or rejected by the Chair of the Meeting in his discretion, and the Chair is under no obligation to accept or reject any particular late proxy.
DATED at Toronto, Ontario this 14th day of April, 2020.
By Order of the Board of Directors

Stephen A. Lang, Chair
