Notes to Proxy

| 1. | All holders of Class B subordinate voting shares have the right to appoint some other person(s) of their choice, who need not be a shareholder, to participate in and act on their behalf at the Meeting.

| 2. | To participate, ask questions and vote at the Meeting virtually, virtual participants (other than guests) will need a control number (see control number set forth on this proxy) and the following password “teck2025” (case sensitive). If you are appointing a proxyholder other than the persons whose names are printed above and who are appointed by Teck YOU MUST return your proxy by mail or by fax or by email to TSX Trust Company (“TSX Trust”) at the coordinates provided below, or by completing an online form at https://www.tsxtrust.com/control-number-request, by 11:00 a.m. (Pacific Time) on December 5, 2025 and provide TSX Trust with the required information for your proxyholder so that TSX Trust may provide the proxyholder with a 13-digit proxyholder control number. Such 13-digit proxyholder control number will differ from the control number set forth on this proxy and will allow your proxyholder to log in to and vote at the Meeting. Without a 13-digit proxyholder control number your proxyholder will only be able to log in to the Meeting as a guest and will not be able to vote.

| 7. | The securities represented by this proxy will be voted as directed by the shareholder; however, if such a specification is not made in respect of any matter, this proxy will be voted FOR such matter by the Teck Management Nominees or, if you appoint another proxyholder, as that other proxyholder sees fit.

| 8. | The securities represented by this proxy will be voted or withheld from voting in accordance with your instructions on any ballot that may be called for, and if you specify a choice with respect to any of these matters, the securities will be voted accordingly.
