Iron Ore Geoscience Australia

2018-12-31  In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
