well...if I am not wrong I remember that at the time as the zinc price was on its highs (around 2 $/lb)we were talking of a break even around 1 - 1.20 $/lb for to run Perkoa on a profitable level. The decision to put Perkoa on care and maintenance must have been taken at a zinc price level between 0.80 - 1 $/lb. Therefore my conclusion is, that the production cost may be around this level (rather on the lower side). I know hat other operations are producing at lower cost. But as I already said: this question can only be answered by BTR.
