While drilling is being undertaken, downhole surveys

are conducted using an Eastman, Pathfinder survey

tool that records the magnetic azimuth and dip of the

hole. These recordings are taken approximately

every 30 metres downhole. Where possible holes are also being surveyed with gyroscopic methods,
