cash cost per ounce, page-2

This is probably just the C1 cost which is the cost of mining and processing. You probably want to know the C3 cost which is the "all up cost". For the C3 cost you need to add Royalty, Depreciation, waste disposal, dencline (if UG), overheads, interest, sustaining CAPEX. Typically these are in $400 - $500/oz range. Other miners have quoted these costs (i.e SLR $415 and NST not broken down but appears to be about the same). RRL should be at the lower end because they have a relatively large resource at a single site.
