Central Eyre Iron Project mining lease approved | Updated SARIG platform |

Olympic Dam drill core available online - view images and key mineralogy of cores from South Australia's world class Copper - Gold - Uranium depost

Thirty diamond-core drill holes, through nearly 20 km of rock, were provided by BHP Billiton to represent an effective 14 km cross section of the Olympic Dam deposit. The cores were scanned with HyLogger™ 3-3 (including the Thermal Infrared) and the spectral data processed against spectral libraries to give interpreted mineralogy. Ancillary data including geochemistry, magnetic susceptibility and density downhole logs were provided by BHP Billiton. All data, including high resolution linescan core images, are available for download from the National Virtual Core Library via SARIG or the Auscope Portal.

The spectral results are presented in the form of the 2 or 3 most dominant minerals for every centimetre along the core – these are labelled Min1, Min2 and Min3. Mineral interpretations are available for each of three spectrometers on the HyLogger™ which record wavelengths in the visible, shortwave infrared, and thermal infrared - uTSAV, uTSAS and uTSAT respectively. Plots of groupings of similar minerals are also provided and designated Grp1, Grp2 and Grp3. Estimates of Errors and relative mineral proportions are included with the data (Error, Wt1-3 respectively).
