After what we've seen so far it's clearly early days at Mace with lots of drilling out needed , then feasability and approvals .Marda has a defined resource and I think mining approval so Marda and underground at EM to happen well before Mace .(Underground ore starts to come in next quarter to be blended with low grade stockpiles .)
Not to say Mace ore won't be handy but how the hell can it happen short term ?
And of course the grade will need to be shown higher or it just won't be truckable .
