All In Sustaining Costs $1325G reports AISC in the range of $894 to $935.
Now, that is a bull$ticks figure. G does not record any green ink this side of $1325 per ounce.
That said, if you take the low end and the high end of their "official" AISC reported to the public and take the median, you need to use a multiple to arrive at the un-BS version.
This is the AISC for G.T
(($894+$935) /2) * 1.45
($1829/2) * 1.45
$914.50 * 1.45
$1326
You have to use a multiplier of 1.45 to get past the BS.
