Freeport-McMoRan Faces Production Setbacks After Fatal Incident at Indonesian Mine

Sep 25, 2025

Freeport-McMoRan, one of the world's largest copper producers, has announced significant production disruptions at its Grasberg Block Cave mine in Indonesia following a fatal mud flow incident. The accident, which occurred on September 8, 2025, resulted in the deaths of two team members, with five others still missing. The company has expressed its condolences to the affected families and is continuing extensive search efforts.

As a result of the disaster, Freeport has declared force majeure at the Grasberg mine, which is the world's second-largest copper operation. This means the company is unable to fulfill some of its delivery contracts due to circumstances beyond its control. Copper deliveries from the mine have been suspended.

Freeport now expects its copper sales for the third quarter to be about 4% lower than previously forecast, with gold sales down nearly 6%. The drop in supply has triggered a spike in copper prices globally and led to a sharp decline in Freeport's share price, which fell over 15% in a single day. Analysts expect the impact on production to last into 2026.
