CDU should be reporting the tonnage and grade of the stockpiles, as the JORC Code is equally applicable to stockpiles. Either report accurately or don't report - but not a halfway house.
To stress again - Rocklands is not a 'unique' style or type of mineralisation. What we are seeing is supergene enrichment (native copper, copper oxides, chalcocite) etc on top of a sulphide dominant hypogene system.
CDU/posters are referring to the native copper dominant mineralisation in the Keweenaw Peninsula in Michigan - this is also native copper dominant (in areas) - but again a different style of mineralisation to CDU. So from a mineralisaion perspective - not a comparable, but on the processing side - some of the historic (native copper) operations would be interesting. TSX Orvana has the advanced (chalcocite dominant) Copperwood project in the area.
