In 2024, the daily production of copper concentrate was 208,365 tons, with the GBC area accounting for 64% [1] - The Grasberg copper mine is an important asset of Freeport - McMoRan, an international mining company headquartered in Phoenix, Arizona, USA [2] - Freeport - McMoRan's Indonesian subsidiary, PT Freeport Indonesia, holds 48.76% of the Grasberg underground mine, and the remaining equity is held by Indonesian state - owned enterprises [3] 2) Production Impact Analysis - After the accident on September 8, all mining operations in the Grasberg mining area stopped.
