Teck Resources Limited announced a mechanical issue at its Carmen de Andacollo (CdA) Operations in Chile requiring a maintenance shutdown of the SAG mill. Company estimate that production will be interrupted for approximately one month for repairs. CDA will mitigate the effect of the interruption by rescheduling other planned plant maintenance to coincide with the mill downtime. The company do not expect a material production impact from the downtime, and our previously disclosed guidance for 2025 total annual copper production and 2025 annual copper production for CdA remains unchanged.

Teck also announced an unrelated temporary outage of the shiploader at the Quebrada Blanca (QB) port facility in Northern Chile. Our preliminary estimate is that repairs to the shiploader will take approximately one month. Operations at the QB mine and plant continue as normal and the operation has capacity to ship via alternative ports.

As a result, we do not expect a material sales impact from the outage and previously disclosed guidance for 2025 annual copper production for QB remains unchanged.
