Rio Tinto is developing Nammuldi as a brownfield development including the satellite deposits at Silvergrass and Homestead. Lycopodium has been working on this project since 2007 when a number of scoping reports and reviews were undertaken.
In late 2009 Lycopodium commenced work on the Preliminary Engineering Study, followed by the Definitive Engineering Study which was completed in December 2011. In January 2012 Lycopodium, in joint venture with URS Australia, was awarded the EPCM contract for infrastructure on the project.
The $3B Nammuldi expansion included two new pits, storage facilities, additional accommodation and increased the production limit from 8 Mtpa to 25 Mtpa for Nammuldi.
First ore production from below the water table was achieved on schedule and budget in September 2014 quarter. It included a remote primary crushing plant, 3 km overland conveyor and wet processing plant.
