Statement

Sample mineralogy was determined by X-ray diffraction and Scanning Electron microscopy (backscattered electron imaging and energy dispersive X-ray spectrometry). Reconnaissance geochemistry was analysed by PXRF. Bulk rock geochemistry by lithium metaborate fusion, nitric acid digestion followed by ICP-MS. Mineral host and leaching behaviour of the REE was determined using a procedure modified from the BCR701 standard sequential extraction methodology. The sequence of extractants was acetic acid (for reactive carbonate hosted), ammonium sulphate solution (for ion exchangable clay hosted), hydrogen peroxide/ammonium acetate (for oxidisable sulphide and organic matter hosted), hydroxylammonium chloride (for reducible oxide hosted). All leachates where analysed using ICP-MS.
