Valuable Mineral Assemblage is expressed both as % in ore and % in HM. Ore Reserves are reported as material within pit designs but limited to below a top-of-ore surface generated from consideration of the optimisation value modelling, discard strategy and current geological domain interpretation. Note 1: Tonnages and grades are rounded to reflect the relative uncertainty of the estimate, thus the sum of columns may not equal. Note 2: HM is within the 38µm to 1mm size fraction and reported as a percentage of the total material, slimes is the -38µm fraction and oversize is the +1mm fraction. The Ore Reserve estimate was prepared by Entech Pty Ltd, an experienced and prominent mining engineering consultancy with appropriate mineral sands experience in accordance with the JORC Code (2012 Edition). The Ore Reserve is estimated using all available geological and relevant drill hole and assay data, including mineralogical sampling and test work on mineral recoveries and final product qualities. Measured and Indicated Mineral Resources were converted to Proved and Probable Ore Reserves respectively, subject to mine design, modifying factors and economic evaluation. The Company is not aware of any new information or data that materially affects the information included in the Ore Reserve estimate.
