The maiden RC drilling programme (announced 25 June 2019) was designed to test down-dip extensions of outcropping lithium-bearing pegmatites where rock-chip samples yielding up to 4.2% Li2O had been identified and lepidolite mineralisation observed in RC drill cuttings.
The drill is operated by a remote compressor that turns the drill pipe and shoe bit, cuts through the bedrock, and allows drill cuttings and any fluids to be removed through the 4-inch to 6-inch diameter borehole and discharged into an on-site storage tank for subsequent removal from the site.
The spectrometer already has participated in thermal-vacuum drill testing at NASA's Glenn Research Center in Cleveland, during which the instrument operated in lunar-like conditions and monitored drill cuttings from H2O-doped lunar simulant for water ice.
