These are just estimates I got from looking at old financial statements...they are by no means perfect numbers....I would suggest looking at an underground mine producer like AEM to get a closer number to ARU's FDN...
Brarrick had revenue of $ 1,642 Mill 2nd Qtr 2007
Net Income of 396 Mill.....that means they had costs of
$1,246 Mill...they sold 2,006 Mill ounzes= 598 cost per ounce
That is a rough figure as there are a lot of timing differences..
As I said I just estimated the 400 to 500...and I think that is low..
