RE: What happened to all the zinc?22 Mar 2019 09:53
The actual recoverable metal may depend on which tailings stockpile is being processed, there's lots of different piles with varying quantities of metals. The initial figures may have been based on one stockpile, and figures yesterday are an estimated average for everything after further testing. Not really enough information to make an informed guess at the moment. But whatever is recoverable it's going to be significant quantities over a long period.
Re the price of vanadium, I've been using Vanadium Pentoxide (V2O5) prices which is what JLP are to be producing, and which is lower than Ferro Vanadium, at $16 lb compared to $70 lb. Both had significant spikes late last year but look to have settled down now. At $16 lb that works out to $35,000 a tonne, producing 1,500 tonnes a year is a pretty significant sum.
