Freeport Provides Update on PT Freeport Indonesia Operations

PHOENIX--(BUSINESS WIRE)-- Freeport (NYSE: FCX) announced today an update on the status of the previously reported mud rush incident at the Grasberg Block Cave mine (GBC) in Indonesia.

On September 20, 2025, PT Freeport Indonesia (PTFI) located two team members who were regrettably fatally injured in the September 8^th incident. The Freeport organization extends its deepest condolences to the families of these individuals.

Extensive efforts are ongoing in the search for five PTFI team members who remain missing. Teams are working around the clock clearing mud and debris and are making steady progress to reach the areas where the remaining team members were working at the time of the incident. These efforts remain our highest priority.

Richard C. Adkerson, Chairman of the Board, and Kathleen Quirk, President and Chief Executive Officer, said, “We are grieving for our coworkers lost in this tragic incident and extend our sincere condolences to the families who lost loved ones and who remain missing. We recently visited the site to offer support to the families and express our appreciation for the extraordinary efforts of the PTFI organization and the emergency response team.”

During the incident, a sudden rush of approximately 800,000 metric tons of wet material entered the mine and traveled rapidly to multiple mine levels, including the service level of the mine where the missing team members were conducting development activities.

To prioritize the search, mining operations in the Grasberg minerals district have been temporarily suspended since September 8^th, as previously reported.

PTFI has commenced an investigation to identify the cause of this incident, which is unprecedented in PTFI’s multi-decade history of block cave mining operations. The investigation team includes external experts and will address root cause analysis and recommendations to safeguard against future occurrences. PTFI expects the investigation to be completed by year-end 2025.

PTFI is working closely with Indonesian government authorities who are reviewing the incident and monitoring the search operations.

In parallel, PTFI will complete an assessment of damage to mobile equipment, rail infrastructure, ore chutes, electrical systems, communication systems and supporting infrastructure.

THIRD QUARTER SALES GUIDANCE

For the third quarter of 2025, FCX’s consolidated sales are expected to be approximately 4% lower for copper and approximately 6% lower for gold than July 2025 estimates.

FUTURE PRODUCTION

The GBC ore body represents 50% of PTFI’s estimated proven and probable reserves as of December 31, 2024, and approximately 70% of PTFI’s previously forecast copper and gold production through 2029. The incident occurred in “PB1C”, one of five production blocks in the GBC but resulted in damage to infrastructure required to support other production areas in the GBC.

PTFI is evaluating the impact of the incident on future production plans. Production forecasts will be revised to incorporate scheduling of required repairs and a phased restart and ramp-up of production.

Sufficient information is not currently available to forecast future production estimates. Preliminary assessments indicate that the impacts are likely to result in the deferral of significant production in the near-term (fourth quarter of 2025 and the year 2026) as repairs are completed and a phased restart and ramp-up of operations commences. A return to pre-incident operating rates could potentially be achieved in 2027.

Currently, PTFI expects the unaffected Big Gossan and Deep MLZ mines could restart operations by mid-fourth quarter 2025, with a phased restart and ramp-up of the GBC mine beginning in the first half of 2026. As a result, PTFI fourth quarter 2025 sales of copper and gold would be insignificant (previously estimated sales of 445 million pounds of copper and 345,000 ounces of gold).

In the first half of 2026, a phased restart and ramp-up of GBC could, initially commence in three production blocks - “PB2” and “PB3”, followed by a third production block “PB1S” in the second half of 2026 and the balance of “PB1C” in 2027. This schedule would target the return to pre-incident estimates in 2027.

Under this phased restart and ramp-up scenario, which is subject to a number of factors and could change, PTFI production in 2026 could potentially be approximately 35% lower than pre-incident estimates (previous production estimates for 2026 approximated 1.7 billion pounds of copper and 1.6 million ounces of gold).

PTFI will seek to optimize production plans as further evaluations are completed. Capital projects will be reviewed and managed to prioritize resources necessary to support restoration of safe production.

PTFI intends to seek recovery of damages under its property and business interruption insurance policies, which cover up to $1.0 billion in losses (subject to a limit of $0.7 billion on underground incidents), after a $0.5 billion deductible.

As a result of the incident and impacts on operations, PTFI is notifying commercial counterparties of a force majeure in accordance with the provisions of its contracts.
