Teck Notification of Technical and Supplemental Updates to the Separation Transaction Terms

VANCOUVER, April 14, 2023 - Teck Resources Ltd. (TSX: TECK.A and TECK.B, NYSE: TECK) ("Teck") today announced certain technical and supplemental updates to the terms of Teck's proposed reorganization to separate into Teck Metals Corp. ("Teck Metals") and Elk Valley Resources Ltd. ("EVR") to be voted on by shareholders on April 26, 2023.

As described in Teck's management proxy circular dated March 23, 2023, the separation provides Teck Metals with continued access to steelmaking coal cash flows for a transition period, through ownership of preferred shares in the capital of EVR and a royalty. The changes to the terms of the separation proposal include permitting the majority holders of the EVR royalty to require EVR to purchase the royalty upon a breach by EVR of the capital expenditure or indebtedness covenants under the Investment Covenant Agreement or upon failure to pay the EVR royalty, in each case that continues unremedied for 15 days.

In addition, the terms of the EVR preferred shares have been updated to (i) make housekeeping changes to address proposed amendments to the Income Tax Act (Canada) related to share buybacks and to the calculation of Free Cash Flow, and (ii) provide holders the right to retract EVR preferred shares upon a breach by EVR of the capital expenditure or indebtedness covenants under the Investment Covenant Agreement that continues unremedied for 15 days. A copy of the revised preferred share terms of EVR will be attached to an amendment to the arrangement agreement between Teck and EVR, which will be filed under Teck's profile on SEDAR (www.sedar.com) and on EDGAR (www.sec.gov), and on Teck's website (www.teck.com).
