HRR - Updated NPV calculation, page-21

So does anyone have an idea of the costs involved in the production of the zinc, copper and lead.

So far what we know is that based on current commodities prices and at full speed they should be bringing in revenue in excess of A$600M per annum assuming the following:

- 70Kt of Zn concentrate at US$3,250 per tonne
- 30Kt of Cu concentrate at US$6,900 per tonne
- 25Kt of Pb concentrate at US$2,400 per tonne.

The whole in figures is the costs of producing/mining these concentrates:

Can anyone help to fill in these gaps?
