Phalaborwa Project – Rainbow Rare Earths

With no need for hard rock mining, crushing and milling, the cost of moving material from the stacks for re-processing will be much lower than those normally associated with mining a primary orebody. Cost of beneficiation to a mixed rare earth carbonate expected to be significantly lower than for a mined mineral rare earth project.
