Regarding The through put rate of Duckhead! it would be blended in with lower grade resource generally from the Pad, so as to not reduce the recovery rate from the higher concentrations... good calc is 95% from ave of 17g/t(you don't want to give the Iron Pigs Gold would you?)
I don't worry myself to much with production rates, so long as the Mill and earth works are trouble free, the oz will take care of itself!
