Kanmantoo Copper mine ready to go ? For real ?, page-97

"Your concern about the excavated material associated development being gangue doesn't effect the cost calculations as the tonnage used is processed tonnage not excavated tonnage."

Regarding development It is a grey area from a statutory accounting perspective , between what is classified as C1 cost for mining a drive leading to a an ore body , or if it amortised over years as a development /.

With out looking at the annual report These guys probably can amortise development as they are likely to have tax losses carried forward they can use to prevent paying tax initially .

Moving right along , at some point in the process, development cost has to be worked into the all in cost to mine per # of Cu , even if it is not a C1 cost it will be accounted for in the NPV and so for financing purposes .
