Iron ore
Prospectivity
Most iron ore production has occurred from the Frances Creek deposits near Pine Creek, which are hydrothermally-enriched hematite deposits within the Pine Creek Orogen. The largest iron ore resources and most current production is located within large oolitic hematite deposits of the Roper iron field in the McArthur Basin.
Large iron ore resources occur in the Roper iron field, hosted in the Roper Group of the McArthur Basin, south of the Roper River. The field contains more than 1 billion tonnes of moderate grade iron ore, with around 85 million tonnes of higher grade direct shipping ore (57-59% Fe) at the Roper Valley and Roper Bar deposits. Mining occurred at Roper Bar in 2013-2014, with export through Bing Bong port. Iron ore in the Roper field varies from massive to oolitic and pisolitic haematite, within the Mesoproterozoic Sherwin Ironstone Member.
Pine Creek Orogen hosts a number of high grade and low tonnage hydrothermally-enriched hematite deposits. This includes the Frances Creek iron ore deposits, which were mined from 1967-1974 and 2007-2014. In June 2021, Linecrest Pty Ltd exported a shipment of iron ore from stockpiles at Frances Creek that had been beneficiated using automated ore sorting technology.
Historical mining of gold- and copper-bearing ironstone at Tennant Creek has produced tailings containing up to 70% magnetite at a number of sites that are located near the Alice Springs-Darwin railway line and existing infrastructure.
