Yeh it does need the cash.

Its focus is Ivanhoe Mines' Oyu Tolgoi, not IVA or SouthGobi.

The proposed sale of its stake by Ivanhoe of SouthGobi to Chalco reflects RIO's priority.

RIO bought into Ivanhoe purely for Oyu Tolgoi.

Given that Oyu Tolgoi needs $4.6b to develop. RIO will need all the money it can get to pay for it, inc. the sale of SouthGobi and IVA.
