The actual number quoted by PQ was $4010 per day to fund mill operations. I also asked if the $50/ ton figure was accurate or more importantly what did it include/exclude. PQ asked the bean counter on additional over head and it was $30K/month. So the math is 30 times $4,000= 120,000 plus 30,000= $150,000/month.
This of course does not include capital expenditures [smelter, mill upgrade and expansion.]
