i forgot to mention, total processing (wet & dry) has a recovery of 53% (including 40% HREE recovery)
1 tonne of ore mined at 289ppm produces 0.15kg of REE in concentrate, worth $8.70 pre-discounting or $3.48 with 60% discount
yet the wet processing alone costs $4/kg
then how much for dry processing?
it seems to be already running a loss with the wet processing
