Thanks for that,
@cokelator! Upgrading to 6% will increase Mt Marion's costs - more ore req, more processing, more reagents etc.
@jakers, I heard something about enviro issues at Greenbushes, they are unable to expand outwards so they have to go deeper hence the cost implications. Can anyone verify this?
So the known costs of Australian producers:
TAW: $381/t
GXY: $325/t
NMT/MIN: $355/t
If BGS can produce sub $275/t, that would make for a pretty compelling investment proposition for this landlocked jungle deposit.
