The Company is not aware of any new information or data that materially affects the information included in the original market announcement. CAUTIONARY STATEMENT; The Company has defined the mineralisation in the field by using hand held pXRF technology to analyse drill samples in real time. This allows for immediate on-site decisions to be made to adjust drilling strategies. While pXRF readings provide a useful indication of mineral content and approximate grades, they are not a substitute for laboratory-derived assay grades and will not be used in any resource estimation. All drill intercepts will be sent to an independent laboratory for accurate analysis, with assay results expected in the current quarter. Portable pXRF results reported are considered semi- quantitative, as such, results from pXRF analysis are stated as indicative only, provide confirmation that mineralisation is present however may not be representative of elemental concentration within the material sampled and are preliminary to subsequent confirmation (or otherwise) by geochemical laboratory analysis. Results of pXRF analyses are included for reference, and laboratory assays will be provided when these become available. Limitations include; very small analysis window, possible inhomogeneous distribution of mineralisation, analytical penetration depth, possible effects from irregular rock surfaces. Results are not considered to be entirely representative of the rock samples, as the analyses were made of what were interpreted to be areas on drill samples with potential to be uranium. The analyses were carried out on drill core specimens and not ground powders. The pXRF is calibrated periodically against prepared standards. The samples that are the subject of this report will be submitted for laboratory assay and some variation from the results presented herein should be expected. Caution should be exercised until the official assay laboratory results have been received. While these preliminary results provide compelling evidence of mineralisation, the Company notes that assay confirmation remains pending and further exploration is required to determine the continuity and thickness of mineralised zones, which will be critical in defining the economic potential of the mineralisation. The Company cautions that visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analysis where concentrates or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The presence of uranium minerals, including uraninite, is based on field observations, pXRF and scintillometer readings only. These indicators are preliminary in nature and should not be considered a substitute for laboratory analysis. The identification of uranium mineralisation remains conceptual until confirmed through geochemical assay and mineralogical reporting from accredited laboratories JORC CODE; It is a requirement of the ASX Listing Rules that the reporting of exploration results, ore reserves and mineral resources in Australia comply with the Joint Ore Reserves Committee’s Australasian Code for Reporting of Mineral Resources and Ore Reserves ("JORC Code"). Investors outside Australia should note that while reporting in this document complies with the JORC Code, they may not comply with the relevant guidelines in other countries. Information contained in this document describing mineral deposits may not be comparable to similar information made public by companies subject to the reporting and disclosure requirements of Canadian or US securities laws.
