Telfer drill core. Upon return from the open pit visit, the group was was taken to the core facility where core from a selection of drill holes was laid out, demonstrating the host succession, the various reefs and associated alteration. They were given the opportunity to study the core and discuss what they saw with Newcrest geologists. Following the core display, the group returned to the function room where one of the tour group delivered a presentation on a major gold deposit in Russia for the benefit of the Newcrest mine and exploration geologists.
