Important Notice Regarding the Availability of Proxy Materials for the Meeting

This year we are using "notice and access" to deliver to shareholders the Circular, Hudbay's audited consolidated financial statements for the years ended December 31, 2020 and 2019 and management's discussion and analysis related thereto and any other proxy-related materials (collectively, the "Proxy-Related Materials") by providing electronic access to such documents instead of mailing paper copies. Notice and access is an environmentally friendly and cost-effective way to distribute these materials since it reduces printing, paper and postage.

The Proxy-Related Materials are available on our website at www.hudbayminerals.com/disclosure-centre, on the website of our transfer agent, TSX Trust Company, at https://docs.tsxtrust.com/2219 and under our profile on SEDAR at www.sedar.com and EDGAR at www.sec.gov/edgar.shtml. Please be sure to review the Circular before voting.

Should you wish to receive a paper copy of the Proxy-Related Materials or if you have any questions about notice and access, please contact our transfer agent, TSX Trust Company, by toll-free telephone at 1-866-600-5869 or by email at TMXEInvestorServices@tmx.com. Paper copies of the Proxy-Related Materials will be made available free of charge. A paper copy will be sent to you within three business days of receiving your request if received in advance of the Meeting or within ten calendar days if a request is received on or after the date of the Meeting and within one year of date the Proxy-Related Materials were filed on SEDAR. If you wish to receive a paper copy of any of these documents before the May 13, 2021 voting deadline, please contact TSX Trust Company by May 3, 2021.

Important Notice Regarding the Virtual Meeting

Hudbay is once again 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.

Shareholders may vote their common shares online or by mail according to the directions on the form of proxy or voting instruction form, as applicable. Registered shareholders and duly appointed proxyholders will be able to attend, participate and vote at the Meeting online at https://web.lumiagm.com/266110387. 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 are unable to attend the virtual Meeting are requested to complete, date, sign and return their form of proxy so that as large a representation as possible may be had at the Meeting.

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.

Hudbay's Board of Directors has fixed the close of business on March 29, 2021 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 March 29, 2021 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 1:00 p.m. (Eastern Time) on May 13, 2021 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. Note that non-registered holders should ensure that their voting instruction form is submitted in accordance with the timeline provided therein, which may be a date prior to the deadline on which proxies must be deposited.

DATED at Toronto, Ontario this 31^st day of March, 2021.

By Order of the Board of Directors
