Century mine is Australia’s largest open cut zinc mine. It began production in 1999 and is located at Lawn Hill, 250km North West of Mount Isa in the Lower Gulf of Carpentaria. Century’s trans-shipping operation is located at Karumba.

Century produces zinc and lead concentrates at its mining and processing operation at Lawn Hill. Concentrates are then transferred in slurry form via a 304-kilometre underground pipeline to Century’s Port facility at Karumba for shipping to smelters in Australia, Europe and Asia.

Century employs approximately 900 people, approximately 20% of whom are Indigenous people who have connections to the Lower Gulf.

Along with other community benefits, Century invests in a training program that sees all graduates paid by MMG Century, but working with host employers in a wide variety of non-mining jobs in their home communities or in locations where they are happy to work. Century’s ground-breaking training program keeps talent in local communities, and reduces dependence on the mine as a source of jobs.

Century is currently in a transition period as it prepares for the end of open cut zinc production in the third quarter of 2015. Rehabilitation planning has already commenced, and MMG’s intention is to return the lease to its pre-mining use as an area suitable for light cattle grazing.

MMG also continues to examine growth options to utilise Century’s extensive infrastructure in the Gulf, with the infrastructure at Lawn Hill and Karumba to remain in a state of operational readiness for several years after the end of production. Growth options include phosphate production, mining of smaller scale, vein deposits, reprocessing zinc currently located in the tailings dams, and processing ore from the Dugald River project.

2014 production at Century of 465,696 tonnes of zinc in zinc concentrate was within production guidance of 455,000–470,000 tonnes. For more information refer to the latest MMG quarterly production report.
