Resources
Australia's total Economic Demonstrated Resources (EDR) of tungsten mine at December 2012 was 391 kilotonnes (kt), a moderate increase from 376 kt in 2011. Increases in EDR were recorded in both Queensland (Qld) and Tasmania (Tas). Australia's EDR are in deposits at Dolphin and Bold Head on King Island in Bass Strait off Tas, Kara and Mount Lindsay in Tas, at Watershed, Mount Carbine and Wolfram Camp in Qld, O'Callaghans, Big Hill and Mount Mulgine in Western Australia (WA) and Molehill in the Northern Territory (NT). The majority of Australia's EDR of tungsten mines are in WA, accounting for about 61%, most of which is in the O'Callaghans deposit (about 50%). Other significant EDR are in Tas which has 21% and Qld with 15.5%.
In 2012, Subeconomic Demonstrated Resources (comprising Para marginal and Sub marginal Resources) were 16 kt, which is equivalent to 4% of the total Demonstrated Resources. Inferred Resources decreased slightly from 107 kt in 2011 to 102 kt in 2012. Queensland accounts for 43% of Inferred Resources, followed by WA with 36%, Tas with 11% and New South Wales (NSW) with 8%.
