In its first phase of operation, from 2004 to 2015, the Savannah Mine was the premier source of copper mining in Western Australia, providing up to 50 percent of the annual production in the state and being the largest producer of the commodity in Western Australia. [22]
Care and maintenance is a term used in the mining industry to describe processes and conditions on a closed mine site at which there is the potential to recommence operations at a later date.

This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground engaging tools. ROM coal can have a large variability of moisture and maximum particle size.
Trona (trisodium hydrogendicarbonate dihydrate, also sodium sesquicarbonate dihydrate, Na 2 CO 3 ·NaHCO 3 ·2H 2 O) is a non-marine evaporite mineral. [4] [6] It is mined as the primary source of sodium carbonate in the United States, where it has replaced the Solvay process used in most of the rest of the world for sodium carbonate production.
