probably irrational to put npvs on a study that wont go to fs/funding for minimum 2 years.  rail studies are are all market driven price and cost assumptions - all you do putting out early npvs is give the eternally uncommitted a kick me sign. same as saying not to talk about a potential fastest route.  potential is potential - it awaits confirmation

sequential reads as Erdenet-Ovoot mirroring Kuragino-Kyzyl line - then later ovoot-Arts Suuri mirroring Kyzyl-Arts Suuri. So an FS to bank with is going to have to incorporate possibly different input assumptions for everthing from steel costs to labour in 2+ yrs time. 

thats the real world - to make big bread all you can do is thumbsuck, knead the dough, measure, knead the dough - till finally you can put it in the oven.  Then you still have to see whether you;ve put it in at the right temp - for all that hard work before
