In 2014, DA Smith (formerly Agapito Associates, Inc. Field Services) completed five CSIRO HI Cell stress measurements for SURF on the 4850 Level under the supervision of Jacobs Associates. DA Smith returned in 2017 to core eight 60-meter HQ3 holes on the 4850 Level for Lawrence Berkeley National Laboratory (LBNL). Borehole collars were cased with 304SS HW casing and Reflex LTD tools used to survey completed holes and for rig set ups (azimuth aligner).
