The Grasberg Block Cave gold mine is managed by PT Freeport Indonesia, a company now majority-owned by the Indonesian government.

In addition to the Grasberg mine, Mimika Regency also houses the Deep Mill Level Zone (DMLZ) gold mine, located in the Grasberg district of Papua.

The DMLZ mine, also managed by PT Freeport Indonesia, contains 77 million tons of identified minerals and an estimated 305 million tons of undetermined minerals. These minerals include a combination of gold, silver, and copper concentrations.

The urban areas that serve as Freeport's centers of activity in Mimika are Tembagapura and Kuala Kencana.
