native copper - tiptoeing around the topic??, page-8

CDU is in an interesting position, but not a specifically unheard of one.

How come AVB had no trouble JORCing their copper rich prospect where the mineralization was, among other things (such as chalcocite), made up of both native and oxidised copper?

For those who are wondering, the only important difference between oxidised and native copper is that the mineral has reacted with oxygen at some point in time. As a copper nugget, it will have a greenish tinge depending on the degree of oxidization.

There is no doubting that there is 'some' native copper down there at Rocklands because we have seen it with our very eyes in company announcements, but the real question is, 'how much'?

AVB could answer that question. CDU haven't been able to.
