[Teck Updates on Chile Operations Maintenance; Annual Guidance Unchanged] Teck Resources Limited announced today that its Carmen de Andacollo (CdA) copper operation in Chile will undergo a maintenance shutdown of its SAG mill due to a mechanical issue. The shutdown is expected to last approximately one month. To mitigate the impact, Teck plans to reschedule other plant maintenance during this period. As a result, the company does not anticipate any material effect on CdA’s or Teck’s overall 2025 annual copper production guidance. Separately, Teck reported an unrelated temporary outage at the shiploader of its Quebrada Blanca (QB) port facility in northern Chile. Repairs are also expected to take about one month. Mine and plant operations at QB remain unaffected, and alternative ports are available for product shipments. Accordingly, the company expects no material impact on QB’s 2025 copper sales or production guidance. Teck reiterated that its full-year copper production and sales forecasts for 2025 remain unchanged, though it cautioned that future outcomes may be subject to risks including repair delays, weather conditions, equipment availability, and logistical constraints.
