The quarterly will be scrutinised for a lot more than just production.  Yes, good production will help with fixed cost dilution - however, the quarterly will be many times more scrutinised for operational C1 (Brook-Hunt) cost, as well as average price received.  All data points which may not be clearly evident in the quarterly, but which a clever analyst could produce at the snap of a finger.

Hence, dont think that good tonnes will mean a good quarterly and hence an uptick (let alone rerate) in the shareprice.  The three needs to be clearly coming together. Tonnes, Cost, and price received.

Think of it as a three-legged stool.  Without any one of those three,  the stool will topple over.
