FCX subsidiaries in the Americas currently operate 15 active tailings storage facilities (TSFs), including 13 in the U.S. and 2 in Peru. We also manage 48 TSFs in the U.S. that are inactive or closed and another nine TSFs that were deemed “safely closed” as of January 31, 2023, according to the definition in the Tailings Standard.
FCX invests significant time and resources to monitor its TSFs effectively. This includes a multi-tiered, continuous review and inspection process that results in recommended actions, which we track until implemented and resolved.
TAILINGS STANDARD IMPLENTATION
In August 2020, the co-conveners of the Global Tailings Review, which included ICMM, published the Tailings Standard which is the first global standard for tailings management that can be applied to existing and future tailings storage facilities. The Tailings Standard includes 77 requirements across six key areas – design, construction, operation and monitoring of tailings facilities, management and governance, use of integrated multi-disciplinary knowledge, engaging with affected stakeholders, emergency response and long-term recovery, and public disclosure. As an ICMM member, FCX is committed to implementing the Tailings Standard by August 2023 for all TSFs with “extreme” or “very high” consequence classifications based on credible failure modes and by August 2025 for all other TSFs. Although our existing tailings management system and associated programs have evolved over many years and are mature and robust, in 2022, FCX continued to advance conformance with the Tailings Standard for our Americas TSFs in line with this commitment.
