Iron Ore | Geoscience Australia
Australia's EDR of iron ore declined from 1994 to 2003 (Figure ) as a result of the combined impacts of increased rates of mine production and mining companies reestimating reserves and resources to comply with the requirements of the JORC Code. Post 2003, EDR increased rapidly to 44 700 Mt in December 2012 (Figure ), due to large increases in magnetite resources .
