Shareholders who participate in householding will continue to have access to and utilize separate proxy voting instructions. We will promptly deliver a separate copy of our Notice or if applicable, our proxy materials to you if you write to our corporate secretary at: 1111 West Hastings Street, 15 th Floor, Vancouver, British Columbia V6E 2J3. If you want to receive your own set of our proxy materials in the future or, if you share an address with another shareholder and together both of you would like to receive only a single set of proxy materials, you should contact your broker or other nominee record holder directly or you may contact us at the above address and phone number. Electronic Delivery of Company Shareholder Communications Most shareholders can elect to view or receive copies of future proxy materials over the Internet instead of receiving paper copies in the mail. You can choose this option and save us the cost of producing and mailing these documents by: • following the instructions provided on your Notice or proxy card; • following the instructions provided when you vote over the Internet; or • going to https://www.cstproxy.com/metals/2025 and following the instructions provided. 8
