Western Plains Resources has updated the mineral resource estimates for its flagship Peculiar Knob direct shipping iron ore project, south of Coober Pedy in South Australia, to take into account the results of the 2010 drilling program. This program was aimed mainly at providing additional drill core for metallurgical testwork, which has not yet been completed, but it did also result in a small increase in the resource tonnage. Total DSO resources, calculated at a 55pc Fe cutoff grade, are now 37.6m tonnes at 62.8pc Fe, 8.0pc SiO2, 0.8pc Al2O3, 0.03pc P and 0.7pc LOI.
