september quaterly query

I am in the process of forecasting Decembers Cash flow and have been looking back on the September Quarterly.

I have a query that i am sure someone can answer.

In table 4 Pk Production Costs it lists the total cost at 1.76 per lb.

However in the Consolidated Statement of Cash flow it lists the total production costs at 54,410,000 if you divide that by the total production of 13254 tonnes (29,220,033 Lbs/Cu) you get a Total production cost per/lb of 1.86.

How is this figure of 54,410,000 comprised?

Thanks in advance
