Century was the largest open pit zinc mine in Australia for more than 15 years. Located in NW Queensland, the mine produced both zinc and lead concentrates that were exported via a dedicated port at Karumba, located north of the mine in the Gulf of Carpentaria. The final capital cost for Century was US$500 million. On 28 February 2017, MMG entered into agreements with Century Mine Rehabilitation Project Pty Ltd, which is a subsidiary of Century Bull Pty Ltd. The company specialises in economic rehabilitation of mine sites and will be responsible for the disposal of assets and infrastructure associated with the Century mine. The sale was approved by MMG's board in February.
