Copper Growth

Teck continues to actively advance its industry-leading copper growth portfolio. The approach is driven by balancing growth and return of capital, value-focused de-risking and the optimization of funding sources.

After carefully assessing multiple configurations for the further expansion of QB beyond the construction of QB2, we have determined that the next phase of development will be the Quebrada Blanca Mill Expansion (QBME) which will entail an increase in concentrator throughput of approximately 50%, with the addition of one identical, semi-autogenous grinding line. We believe this configuration optimizes the timeline to progress the development of this world-class orebody, while leveraging existing infrastructure to maximize capital efficiency. The QBME prefeasibility study, including all environmental baseline activities, commenced in the fourth quarter of 2021 with completion targeted in the fourth quarter of 2022. QBME will be a significant contributor to our near-term copper growth portfolio with first production targeted for 2026.

At Zafranal, for which a feasibility study has been completed, we received confirmation of SEIA admissibility in the first quarter of 2022. At San Nicolás, we commenced work on a feasibility study in the first quarter of 2022 with completion targeted in the fourth quarter of 2023. Partnering negotiations for San Nicolás are ongoing and first production is targeted for 2026. At Galore Creek, Fluor was appointed to undertake a prefeasibility study starting in the first quarter of 2022, with completion targeted in the first half of 2023. Strategic, technical and commercial assessments for the advancement of NuevaUnión, Mesaba and Schaft Creek are ongoing.
