Ann: Matilda/Wiluna Production Update, page-83

I would certainly expect that the head grade should improve substantially. Presumably you have to move a lot of low grade dirt to get to the good stuff in an open pit AND this would be made very difficult with wet, boggy earth.

Perhaps there will also be more info on the success or otherwise of the re-modelling of the underground.

Those are the two strangle points at the moment. If progress isn't made in these areas THEN you have to wonder whether their mining assumptions are quite different from what they are actually experiencing. We can only wait.
