An article by Mongabay from 2017 alleges that PT Freeport Indonesia (PTFI) never compensated the Amungme and Kamoro people on the land where it operates its Grasberg gold and copper mine. The article also alleges that PTFI was using land in protected forests without the proper permits. Freeport McMoRan responded that all land used by its subsidiary PTFI has been legally and formally released by customary land owners through a contract with the government.
