Iron ore

The Northern Territory contains a number of iron ore deposits with three periods of mining from 1967-1974, 2007-2014 and 2020-present producing more than 18 million tonnes of iron ore.

Remaining JORC resources
~100 Mt of DSO iron ore (>55% Fe)

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.

Roper Bar is an open-cut iron ore mine located 55km southeast of Ngukurr in the Roper Group of the McArthur Basin. The mine operated briefly in 2013-15 before closing due to a low iron ore price. Current owners Nathan River Resources Pty Ltd (a subsidiary of British Marine Ltd) recommenced iron ore production in October 2020.

Iron ore from Roper Bar is transported via a 170 km haul road to the Bing Bong load-out facility. Planned annual production is 1.5 million tonnes of iron ore per annum.

Projects

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.

In approvals process

Iron resources also occur as part of TNG Ltd’s Mount Peake vanadium-rich magnetite project in the Aileron Province, where feasibility studies propose the production of high purity Fe2O3 with vanadium pentoxide and titanium dioxide.

Exploration results


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.
