Ann: Half Year Accounts, page-62

I thought with the larger strip ratio costs are higher and it was far more likely lower grade ore and waste to be included in the processing stream despite a guy in the pit directing the operations as to what goes where.
I realise grade is low in the initial stage 1, but as it goes deeper grade is supposed to improve which is why the average grade is higher. A few of the old drill results were showing higher grade shoots at depths of 10m. Shouldn't we be intersecting them by now ?
