So just looking at some rough calculations if we do indeed join up with Prince:
We already have 1.5kms long plus 2kms to get to Prince plus 2.2kms at prince
= 5.7kms long at 700mtr wide.
Greenbushes is only 3kms long and 300mtrs wide.
You do the maths but it looks like Kidman could have the largest deposit in the world!!
