cux's lower cost per tonne of ore., page-6

CUX is estimating, subject to confirmation of the scoping study, that total cost of extraction and wet procesing to be in the order of ~$4/tonne.

exactly which presentation is being referred to here????

anyway, wet processing has a total recovery of 68% (including 55% for HREE)

at 289ppm, 1 tonne will recover 0.18/kg of REE

at $4/t, cost is $4 per 0.18/kg or $20.35/kg

then there is the cost of the dry processing

CUX basket price is $58/kg

CUX may produce a 44% concentrate, for which they may receive 40% of the basket price for, due to heavy discounting

looks hopeless to me
