Teck Provides Update on QBME Regulatory Application

VANCOUVER, Oct. 24, 2023 - Teck Resources Ltd. (TSX: TECK.A and TECK.B, NYSE: TECK) ("Teck") noted that today, following recent receipt of feedback from regulators, it has withdrawn the environmental permit application for the Quebrada Blanca Mill Expansion ("QBME") project to allow time to consider this feedback, better understand the full capability of QB, and submit a revised permit application.

This is part of the ongoing regulatory process, and withdrawing now will allow time to incorporate regulatory feedback and to further optimize the scope of the project. Submission of a revised application would add approximately 12 months to the overall regulatory process from the date of submission. Teck does not anticipate a sanction decision on QBME prior to completion of ramp up and assessment of the full capability of the existing QB asset and receipt of regulatory approval.

The QBME project is a proposed future expansion which would increase QB's throughput, leveraging existing tailings and other infrastructure with minimal additional footprint.
