hi ddzx just wondering how you got your Pb metal tonnes of 1011,000 as I got 1141 000
1.8mtpa * 13 years * 6.1% * 80% recovery = 1,142,ooo tonnes LOM and at spot of $2041 a tonne = US$2.3B LOM from Pb
for the mine I get a Pb eq of 13% and have not included Cu in that .
Maybe it would be best to convert to a Pb eq so we are all on the same page ???
