Rainbow Rare Earths Ltd. announced that it has completed an auger drilling programme at the Phalaborwa Rare Earths Project, which was planned to deliver an inferred JORC (2012) resource classification, within the 35 million tonne gypsum stacks. Assay samples have been dispatched to SGS laboratories in South Africa, with results expected during first quarter of 2021. The drilling programme was completed ahead of schedule and under budget. A metallurgical test programme will also be conducted from the drill samples to facilitate process optimisation of the original processing flow sheet, developed by Sasol, which enabled the successful operation of a pilot plant to produce over three tonnes of mixed rare earth carbonate.
