Drill core at Carrapateena.   After an initiall introduction to the core on display, but mainly following the main presentation, the group was led through a series of drill holes cutting the ore zone and wallrocks by senior OZ Minerals geologists Mick Sawyer (centre of lower-right image) and Bruce Whittaker (second from right, upper-right image). This core was particularly interesting and promoted considerable discussion and comparisons/contrasts to Olympic Dam and kept the group engaged for several hours. The overcast and a brief, sharp storm, tempered the hot summer climate and wet the core.   Photographs by Mike Porter.
